+Like other projects, we also have some guidelines to keep to the
+code.  For Git in general, a few rough rules are:
+
+ - Most importantly, we never say "It's in POSIX; we'll happily
+   ignore your needs should your system not conform to it."
+   We live in the real world.
+
+ - However, we often say "Let's stay away from that construct,
+   it's not even in POSIX".
+
+ - In spite of the above two rules, we sometimes say "Although
+   this is not in POSIX, it (is so convenient | makes the code
+   much more readable | has other good characteristics) and
+   practically all the platforms we care about support it, so
+   let's use it".
+
+   Again, we live in the real world, and it is sometimes a
+   judgement call, the decision based more on real world
+   constraints people face than what the paper standard says.
+
+ - Fixing style violations while working on a real change as a
+   preparatory clean-up step is good, but otherwise avoid useless code
+   churn for the sake of conforming to the style.
+
+   "Once it _is_ in the tree, it's not really worth the patch noise to
+   go and fix it up."
+   Cf. http://article.gmane.org/gmane.linux.kernel/943020
+
+Make your code readable and sensible, and don't try to be clever.
+
+As for more concrete guidelines, just imitate the existing code
+(this is a good guideline, no matter which project you are
+contributing to). It is always preferable to match the _local_
+convention. New code added to Git suite is expected to match
+the overall style of existing code. Modifications to existing
+code is expected to match the style the surrounding code already
+uses (even if it doesn't match the overall style of existing code).
+
+But if you must have a list of rules, here they are.
+
+For shell scripts specifically (not exhaustive):
+
+ - We use tabs for indentation.
+
+ - Case arms are indented at the same depth as case and esac lines,
+   like this:
+
+	case "$variable" in
+	pattern1)
+		do this
+		;;
+	pattern2)
+		do that
+		;;
+	esac
+
+ - Redirection operators should be written with space before, but no
+   space after them.  In other words, write 'echo test >"$file"'
+   instead of 'echo test> $file' or 'echo test > $file'.  Note that
+   even though it is not required by POSIX to double-quote the
+   redirection target in a variable (as shown above), our code does so
+   because some versions of bash issue a warning without the quotes.
+
+	(incorrect)
+	cat hello > world < universe
+	echo hello >$world
+
+	(correct)
+	cat hello >world <universe
+	echo hello >"$world"
+
+ - We prefer $( ... ) for command substitution; unlike ``, it
+   properly nests.  It should have been the way Bourne spelled
+   it from day one, but unfortunately isn't.
+
+ - If you want to find out if a command is available on the user's
+   $PATH, you should use 'type <command>', instead of 'which <command>'.
+   The output of 'which' is not machine parseable and its exit code
+   is not reliable across platforms.
+
+ - We use POSIX compliant parameter substitutions and avoid bashisms;
+   namely:
+
+   - We use ${parameter-word} and its [-=?+] siblings, and their
+     colon'ed "unset or null" form.
+
+   - We use ${parameter#word} and its [#%] siblings, and their
+     doubled "longest matching" form.
+
+   - No "Substring Expansion" ${parameter:offset:length}.
+
+   - No shell arrays.
+
+   - No strlen ${#parameter}.
+
+   - No pattern replacement ${parameter/pattern/string}.
+
+ - We use Arithmetic Expansion $(( ... )).
+
+ - Inside Arithmetic Expansion, spell shell variables with $ in front
+   of them, as some shells do not grok $((x)) while accepting $(($x))
+   just fine (e.g. dash older than 0.5.4).
+
+ - We do not use Process Substitution <(list) or >(list).
+
+ - Do not write control structures on a single line with semicolon.
+   "then" should be on the next line for if statements, and "do"
+   should be on the next line for "while" and "for".
+
+	(incorrect)
+	if test -f hello; then
+		do this
+	fi
+
+	(correct)
+	if test -f hello
+	then
+		do this
+	fi
+
+ - We prefer "test" over "[ ... ]".
+
+ - We do not write the noiseword "function" in front of shell
+   functions.
+
+ - We prefer a space between the function name and the parentheses,
+   and no space inside the parentheses. The opening "{" should also
+   be on the same line.
+
+	(incorrect)
+	my_function(){
+		...
+
+	(correct)
+	my_function () {
+		...
+
+ - As to use of grep, stick to a subset of BRE (namely, no \{m,n\},
+   [::], [==], or [..]) for portability.
+
+   - We do not use \{m,n\};
+
+   - We do not use -E;
+
+   - We do not use ? or + (which are \{0,1\} and \{1,\}
+     respectively in BRE) but that goes without saying as these
+     are ERE elements not BRE (note that \? and \+ are not even part
+     of BRE -- making them accessible from BRE is a GNU extension).
+
+ - Use Git's gettext wrappers in git-sh-i18n to make the user
+   interface translatable. See "Marking strings for translation" in
+   po/README.
+
+ - We do not write our "test" command with "-a" and "-o" and use "&&"
+   or "||" to concatenate multiple "test" commands instead, because
+   the use of "-a/-o" is often error-prone.  E.g.
+
+     test -n "$x" -a "$a" = "$b"
+
+   is buggy and breaks when $x is "=", but
+
+     test -n "$x" && test "$a" = "$b"
+
+   does not have such a problem.
+
+
+For C programs:
+
+ - We use tabs to indent, and interpret tabs as taking up to
+   8 spaces.
+
+ - We try to keep to at most 80 characters per line.
+
+ - We try to support a wide range of C compilers to compile Git with,
+   including old ones. That means that you should not use C99
+   initializers, even if a lot of compilers grok it.
+
+ - Variables have to be declared at the beginning of the block.
+
+ - NULL pointers shall be written as NULL, not as 0.
+
+ - When declaring pointers, the star sides with the variable
+   name, i.e. "char *string", not "char* string" or
+   "char * string".  This makes it easier to understand code
+   like "char *string, c;".
+
+ - Use whitespace around operators and keywords, but not inside
+   parentheses and not around functions. So:
+
+        while (condition)
+		func(bar + 1);
+
+   and not:
+
+        while( condition )
+		func (bar+1);
+
+ - We avoid using braces unnecessarily.  I.e.
+
+	if (bla) {
+		x = 1;
+	}
+
+   is frowned upon.  A gray area is when the statement extends
+   over a few lines, and/or you have a lengthy comment atop of
+   it.  Also, like in the Linux kernel, if there is a long list
+   of "else if" statements, it can make sense to add braces to
+   single line blocks.
+
+ - We try to avoid assignments in the condition of an "if" statement.
+
+ - Try to make your code understandable.  You may put comments
+   in, but comments invariably tend to stale out when the code
+   they were describing changes.  Often splitting a function
+   into two makes the intention of the code much clearer.
+
+ - Multi-line comments include their delimiters on separate lines from
+   the text.  E.g.
+
+	/*
+	 * A very long
+	 * multi-line comment.
+	 */
+
+   Note however that a comment that explains a translatable string to
+   translators uses a convention of starting with a magic token
+   "TRANSLATORS: " immediately after the opening delimiter, even when
+   it spans multiple lines.  We do not add an asterisk at the beginning
+   of each line, either.  E.g.
+
+	/* TRANSLATORS: here is a comment that explains the string
+	   to be translated, that follows immediately after it */
+	_("Here is a translatable string explained by the above.");
+
+ - Double negation is often harder to understand than no negation
+   at all.
+
+ - There are two schools of thought when it comes to comparison,
+   especially inside a loop. Some people prefer to have the less stable
+   value on the left hand side and the more stable value on the right hand
+   side, e.g. if you have a loop that counts variable i down to the
+   lower bound,
+
+	while (i > lower_bound) {
+		do something;
+		i--;
+	}
+
+   Other people prefer to have the textual order of values match the
+   actual order of values in their comparison, so that they can
+   mentally draw a number line from left to right and place these
+   values in order, i.e.
+
+	while (lower_bound < i) {
+		do something;
+		i--;
+	}
+
+   Both are valid, and we use both.  However, the more "stable" the
+   stable side becomes, the more we tend to prefer the former
+   (comparison with a constant, "i > 0", is an extreme example).
+   Just do not mix styles in the same part of the code and mimic
+   existing styles in the neighbourhood.
+
+ - There are two schools of thought when it comes to splitting a long
+   logical line into multiple lines.  Some people push the second and
+   subsequent lines far enough to the right with tabs and align them:
+
+        if (the_beginning_of_a_very_long_expression_that_has_to ||
+		span_more_than_a_single_line_of ||
+		the_source_text) {
+                ...
+
+   while other people prefer to align the second and the subsequent
+   lines with the column immediately inside the opening parenthesis,
+   with tabs and spaces, following our "tabstop is always a multiple
+   of 8" convention:
+
+        if (the_beginning_of_a_very_long_expression_that_has_to ||
+	    span_more_than_a_single_line_of ||
+	    the_source_text) {
+                ...
+
+   Both are valid, and we use both.  Again, just do not mix styles in
+   the same part of the code and mimic existing styles in the
+   neighbourhood.
+
+ - When splitting a long logical line, some people change line before
+   a binary operator, so that the result looks like a parse tree when
+   you turn your head 90-degrees counterclockwise:
+
+        if (the_beginning_of_a_very_long_expression_that_has_to
+	    || span_more_than_a_single_line_of_the_source_text) {
+
+   while other people prefer to leave the operator at the end of the
+   line:
+
+        if (the_beginning_of_a_very_long_expression_that_has_to ||
+	    span_more_than_a_single_line_of_the_source_text) {
+
+   Both are valid, but we tend to use the latter more, unless the
+   expression gets fairly complex, in which case the former tends to
+   be easier to read.  Again, just do not mix styles in the same part
+   of the code and mimic existing styles in the neighbourhood.
+
+ - When splitting a long logical line, with everything else being
+   equal, it is preferable to split after the operator at higher
+   level in the parse tree.  That is, this is more preferable:
+
+	if (a_very_long_variable * that_is_used_in +
+	    a_very_long_expression) {
+		...
+
+   than
+
+	if (a_very_long_variable *
+	    that_is_used_in + a_very_long_expression) {
+		...
+
+ - Some clever tricks, like using the !! operator with arithmetic
+   constructs, can be extremely confusing to others.  Avoid them,
+   unless there is a compelling reason to use them.
+
+ - Use the API.  No, really.  We have a strbuf (variable length
+   string), several arrays with the ALLOC_GROW() macro, a
+   string_list for sorted string lists, a hash map (mapping struct
+   objects) named "struct decorate", amongst other things.
+
+ - When you come up with an API, document it.
+
+ - The first #include in C files, except in platform specific compat/
+   implementations, must be either "git-compat-util.h", "cache.h" or
+   "builtin.h".  You do not have to include more than one of these.
+
+ - A C file must directly include the header files that declare the
+   functions and the types it uses, except for the functions and types
+   that are made available to it by including one of the header files
+   it must include by the previous rule.
+
+ - If you are planning a new command, consider writing it in shell
+   or perl first, so that changes in semantics can be easily
+   changed and discussed.  Many Git commands started out like
+   that, and a few are still scripts.
+
+ - Avoid introducing a new dependency into Git. This means you
+   usually should stay away from scripting languages not already
+   used in the Git core command set (unless your command is clearly
+   separate from it, such as an importer to convert random-scm-X
+   repositories to Git).
+
+ - When we pass <string, length> pair to functions, we should try to
+   pass them in that order.
+
+ - Use Git's gettext wrappers to make the user interface
+   translatable. See "Marking strings for translation" in po/README.
+
+For Perl programs:
+
+ - Most of the C guidelines above apply.
+
+ - We try to support Perl 5.8 and later ("use Perl 5.008").
+
+ - use strict and use warnings are strongly preferred.
+
+ - Don't overuse statement modifiers unless using them makes the
+   result easier to follow.
+
+	... do something ...
+	do_this() unless (condition);
+        ... do something else ...
+
+   is more readable than:
+
+	... do something ...
+	unless (condition) {
+		do_this();
+	}
+        ... do something else ...
+
+   *only* when the condition is so rare that do_this() will be almost
+   always called.
+
+ - We try to avoid assignments inside "if ()" conditions.
+
+ - Learn and use Git.pm if you need that functionality.
+
+ - For Emacs, it's useful to put the following in
+   GIT_CHECKOUT/.dir-locals.el, assuming you use cperl-mode:
+
+    ;; note the first part is useful for C editing, too
+    ((nil . ((indent-tabs-mode . t)

+
+For Python scripts:
+
+ - We follow PEP-8 (http://www.python.org/dev/peps/pep-0008/).
+
+ - As a minimum, we aim to be compatible with Python 2.6 and 2.7.
+
+ - Where required libraries do not restrict us to Python 2, we try to
+   also be compatible with Python 3.1 and later.
+
+ - When you must differentiate between Unicode literals and byte string
+   literals, it is OK to use the 'b' prefix.  Even though the Python
+   documentation for version 2.6 does not mention this prefix, it has
+   been supported since version 2.6.0.
+
+Error Messages
+
+ - Do not end error messages with a full stop.
+
+ - Do not capitalize ("unable to open %s", not "Unable to open %s")
+
+ - Say what the error is first ("cannot open %s", not "%s: cannot open")
+
+
+Externally Visible Names
+
+ - For configuration variable names, follow the existing convention:
+
+   . The section name indicates the affected subsystem.
+
+   . The subsection name, if any, indicates which of an unbounded set
+     of things to set the value for.
+
+   . The variable name describes the effect of tweaking this knob.
+
+   The section and variable names that consist of multiple words are
+   formed by concatenating the words without punctuations (e.g. `-`),
+   and are broken using bumpyCaps in documentation as a hint to the
+   reader.
+
+   When choosing the variable namespace, do not use variable name for
+   specifying possibly unbounded set of things, most notably anything
+   an end user can freely come up with (e.g. branch names).  Instead,
+   use subsection names or variable values, like the existing variable
+   branch.<name>.description does.
+
+
+Writing Documentation:
+
+ Most (if not all) of the documentation pages are written in the
+ AsciiDoc format in *.txt files (e.g. Documentation/git.txt), and
+ processed into HTML and manpages (e.g. git.html and git.1 in the
+ same directory).
+
+ The documentation liberally mixes US and UK English (en_US/UK)
+ norms for spelling and grammar, which is somewhat unfortunate.
+ In an ideal world, it would have been better if it consistently
+ used only one and not the other, and we would have picked en_US
+ (if you wish to correct the English of some of the existing
+ documentation, please see the documentation-related advice in the
+ Documentation/SubmittingPatches file).
+
+ Every user-visible change should be reflected in the documentation.
+ The same general rule as for code applies -- imitate the existing
+ conventions.
+
+ A few commented examples follow to provide reference when writing or
+ modifying command usage strings and synopsis sections in the manual
+ pages:
+
+ Placeholders are spelled in lowercase and enclosed in angle brackets:
+   <file>
+   --sort=<key>
+   --abbrev[=<n>]
+
+ If a placeholder has multiple words, they are separated by dashes:
+   <new-branch-name>
+   --template=<template-directory>
+
+ Possibility of multiple occurrences is indicated by three dots:
+   <file>...
+   (One or more of <file>.)
+
+ Optional parts are enclosed in square brackets:
+   [<extra>]
+   (Zero or one <extra>.)
+
+   --exec-path[=<path>]
+   (Option with an optional argument.  Note that the "=" is inside the
+   brackets.)
+
+   [<patch>...]
+   (Zero or more of <patch>.  Note that the dots are inside, not
+   outside the brackets.)
+
+ Multiple alternatives are indicated with vertical bars:
+   [-q | --quiet]
+   [--utf8 | --no-utf8]
+
+ Parentheses are used for grouping:
+   [(<rev> | <range>)...]
+   (Any number of either <rev> or <range>.  Parens are needed to make
+   it clear that "..." pertains to both <rev> and <range>.)
+
+   [(-p <parent>)...]
+   (Any number of option -p, each with one <parent> argument.)
+
+   git remote set-head <name> (-a | -d | <branch>)
+   (One and only one of "-a", "-d" or "<branch>" _must_ (no square
+   brackets) be provided.)
+
+ And a somewhat more contrived example:
+   --diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]
+   Here "=" is outside the brackets, because "--diff-filter=" is a
+   valid usage.  "*" has its own pair of brackets, because it can
+   (optionally) be specified only when one or more of the letters is
+   also provided.
+
+  A note on notation:
+   Use 'git' (all lowercase) when talking about commands i.e. something
+   the user would type into a shell and use 'Git' (uppercase first letter)
+   when talking about the version control system and its properties.
+
+ A few commented examples follow to provide reference when writing or
+ modifying paragraphs or option/command explanations that contain options
+ or commands:
+
+ Literal examples (e.g. use of command-line options, command names, and
+ configuration variables) are typeset in monospace, and if you can use
+ `backticks around word phrases`, do so.
+   `--pretty=oneline`
+   `git rev-list`
+   `remote.pushDefault`
+
+ Word phrases enclosed in `backtick characters` are rendered literally
+ and will not be further expanded. The use of `backticks` to achieve the
+ previous rule means that literal examples should not use AsciiDoc
+ escapes.
+   Correct:
+      `--pretty=oneline`
+   Incorrect:
+      `\--pretty=oneline`
+
+ If some place in the documentation needs to typeset a command usage
+ example with inline substitutions, it is fine to use +monospaced and
+ inline substituted text+ instead of `monospaced literal text`, and with
+ the former, the part that should not get substituted must be
+ quoted/escaped.

-GIT v1.5.1 Release Notes
-========================
-
-Updates since v1.5.0
---------------------
-
-* Deprecated commands and options.
-
-  - git-diff-stages and git-resolve have been removed.
-
-* New commands and options.
-
-  - "git log" and friends take --reverse.  This makes output
-    that typically goes reverse order in chronological order.
-    "git shortlog" usually lists commits in chronological order,
-    but with "--reverse", they are shown in reverse
-    chronological order.
-
-  - "git diff" learned --ignore-space-at-eol.  This is a weaker
-    form of --ignore-space-change.
-
-  - "git diff --no-index pathA pathB" can be used as diff
-    replacement with git specific enhancements.
-
-  - "git diff --pretty=format:<string>" to allow more flexible
-    custom log output.
-
-  - "git name-rev" learned --refs=<pattern>, to limit the tags
-    used for naming the given revisions only to the ones
-    matching the given pattern.
-
-  - "git remote update" is to run "git fetch" for defined remotes
-    to update tracking branches.
-
-  - "git cvsimport" can now take '-d' to talk with a CVS
-    repository different from what are recorded in CVS/Root
-    (overriding it with environment CVSROOT does not work).
-
-  - "git bundle" can help sneaker-netting your changes between
-    repositories.
-
-  - A new configuration "core.symlinks" can be used to disable
-    symlinks on filesystems that do not support them; they are
-    checked out as regular files instead.
-
-
-* Updated behaviour of existing commands.
-
-  - git-svn got almost a rewrite.
-
-  - core.autocrlf configuration, when set to 'true', makes git
-    to convert CRLF at the end of lines in text files to LF when
-    reading from the filesystem, and convert in reverse when
-    writing to the filesystem.  The variable can be set to
-    'input', in which case the conversion happens only while
-    reading from the filesystem but files are written out with
-    LF at the end of lines.  Currently, which paths to consider
-    'text' (i.e. be subjected to the autocrlf mechanism) is
-    decided purely based on the contents, but the plan is to
-    allow users to explicitly override this heuristic based on
-    paths.
-
-  - The behaviour of 'git-apply', when run in a subdirectory,
-    without --index nor --cached were inconsistent with that of
-    the command with these options.  This was fixed to match the
-    behaviour with --index.  A patch that is meant to be applied
-    with -p1 from the toplevel of the project tree can be
-    applied with any custom -p<n> option.  A patch that is not
-    relative to the toplevel needs to be applied with -p<n>
-    option with or without --index (or --cached).
-
-  - "git diff" outputs a trailing HT when pathnames have embedded
-    SP on +++/--- header lines, in order to help "GNU patch" to
-    parse its output.  "git apply" was already updated to accept
-    this modified output format since ce74618d (Sep 22, 2006).
-
-  - "git cvsserver" runs hooks/update and honors its exit status.
-
-  - "git cvsserver" can be told to send everything with -kb.
-
-  - "git diff --check" also honors the --color output option.
-
-  - "git name-rev" used to stress the fact that a ref is a tag too
-    much, by saying something like "v1.2.3^0~22".  It now says
-    "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
-    not talk about an ancestor of the commit that is tagged, which
-    makes sense).
-
-  - "git rev-list --boundary" now shows boundary markers for the
-    commits omitted by --max-age and --max-count condition.
-
-  - The configuration mechanism now reads $(prefix)/etc/gitconfig.
-
-  - "git apply --verbose" shows what preimage lines were wanted
-    when it couldn't find them.
-
-  - "git status" in a read-only repository got a bit saner.
-
-  - "git fetch" (hence "git clone" and "git pull") are less
-    noisy when the output does not go to tty.
-
-* Hooks
-
-  - The sample update hook to show how to send out notification
-    e-mail was updated to show only new commits that appeared in
-    the repository.  Earlier, it showed new commits that appeared
-    on the branch.

+GIT v1.5.1.1 Release Notes
+==========================
+
+Fixes since v1.5.1
+------------------
+
+* Documentation updates
+
+  - The --left-right option of rev-list and friends is documented.
+
+  - The documentation for cvsimport has been majorly improved.
+
+  - "git-show-ref --exclude-existing" was documented.
+
+* Bugfixes
+
+  - The implementation of -p option in "git cvsexportcommit" had
+    the meaning of -C (context reduction) option wrong, and
+    loosened the context requirements when it was told to be
+    strict.
+
+  - "git cvsserver" did not behave like the real cvsserver when
+    client side removed a file from the working tree without
+    doing anything else on the path.  In such a case, it should
+    restore it from the checked out revision.
+
+  - "git fsck" issued an alarming error message on detached
+    HEAD.  It is not an error since at least 1.5.0.
+
+  - "git send-email" produced of References header of unbounded length;
+    fixed this with line-folding.
+
+  - "git archive" to download from remote site should not
+    require you to be in a git repository, but it incorrectly
+    did.
+
+  - "git apply" ignored -p<n> for "diff --git" formatted
+    patches.
+
+  - "git rerere" recorded a conflict that had one side empty
+    (the other side adds) incorrectly; this made merging in the
+    other direction fail to use previously recorded resolution.
+
+  - t4200 test was broken where "wc -l" pads its output with
+    spaces.
+
+  - "git branch -m old new" to rename branch did not work
+    without a configuration file in ".git/config".
+
+  - The sample hook for notification e-mail was misnamed.
+
+  - gitweb did not show type-changing patch correctly in the
+    blobdiff view.
+
+  - git-svn did not error out with incorrect command line options.
+
+  - git-svn fell into an infinite loop when insanely long commit
+    message was found.
+
+  - git-svn dcommit and rebase was confused by patches that were
+    merged from another branch that is managed by git-svn.
+
+  - git-svn used to get confused when globbing remote branch/tag
+    spec (e.g. "branches = proj/branches/*:refs/remotes/origin/*")
+    is used and there was a plain file that matched the glob.

+GIT v1.5.1.2 Release Notes
+==========================
+
+Fixes since v1.5.1.1
+--------------------
+
+* Bugfixes
+
+  - "git clone" over http from a repository that has lost the
+    loose refs by running "git pack-refs" were broken (a code to
+    deal with this was added to "git fetch" in v1.5.0, but it
+    was missing from "git clone").
+
+  - "git diff a/ b/" incorrectly fell in "diff between two
+    filesystem objects" codepath, when the user most likely
+    wanted to limit the extent of output to two tracked
+    directories.
+
+  - git-quiltimport had the same bug as we fixed for
+    git-applymbox in v1.5.1.1 -- it gave an alarming "did not
+    have any patch" message (but did not actually fail and was
+    harmless).
+
+  - various git-svn fixes.
+
+  - Sample update hook incorrectly always refused requests to
+    delete branches through push.
+
+  - git-blame on a very long working tree path had buffer
+    overrun problem.
+
+  - git-apply did not like to be fed two patches in a row that created
+    and then modified the same file.
+
+  - git-svn was confused when a non-project was stored directly under
+    trunk/, branches/ and tags/.
+
+  - git-svn wants the Error.pm module that was at least as new
+    as what we ship as part of git; install ours in our private
+    installation location if the one on the system is older.
+
+  - An earlier update to command line integer parameter parser was
+    botched and made 'update-index --cacheinfo' completely useless.
+
+
+* Documentation updates
+
+  - Various documentation updates from J. Bruce Fields, Frank
+    Lichtenheld, Alex Riesen and others.  Andrew Ruder started a
+    war on undocumented options.

+GIT v1.5.1.3 Release Notes
+==========================
+
+Fixes since v1.5.1.2
+--------------------
+
+* Bugfixes
+
+  - git-add tried to optimize by finding common leading
+    directories across its arguments but botched, causing very
+    confused behaviour.
+
+  - unofficial rpm.spec file shipped with git was letting
+    ETC_GITCONFIG set to /usr/etc/gitconfig.  Tweak the official
+    Makefile to make it harder for distro people to make the
+    same mistake, by setting the variable to /etc/gitconfig if
+    prefix is set to /usr.
+
+  - git-svn inconsistently stripped away username from the URL
+    only when svnsync_props was in use.
+
+  - git-svn got confused when handling symlinks on Mac OS.
+
+  - git-send-email was not quoting recipient names that have
+    period '.' in them.  Also it did not allow overriding
+    envelope sender, which made it impossible to send patches to
+    certain subscriber-only lists.
+
+  - built-in write_tree() routine had a sequence that renamed a
+    file that is still open, which some systems did not like.
+
+  - when memory is very tight, sliding mmap code to read
+    packfiles incorrectly closed the fd that was still being
+    used to read the pack.
+
+  - import-tars contributed front-end for fastimport was passing
+    wrong directory modes without checking.
+
+  - git-fastimport trusted its input too much and allowed to
+    create corrupt tree objects with entries without a name.
+
+  - git-fetch needlessly barfed when too long reflog action
+    description was given by the caller.
+
+Also contains various documentation updates.

+  - "git diff" learned --ignore-space-at-eol.  This is a weaker
+    form of --ignore-space-change.

+  - "git diff --no-index pathA pathB" can be used as diff
+    replacement with git specific enhancements.
+
+  - "git diff --no-index" can read from '-' (standard input).
+
+  - "git diff" also learned --exit-code to exit with non-zero
+    status when it found differences.  In the future we might
+    want to make this the default but that would be a rather big
+    backward incompatible change; it will stay as an option for
+    now.
+
+  - "git diff --quiet" is --exit-code with output turned off,
+    meant for scripted use to quickly determine if there is any
+    tree-level difference.
+
+  - Textual patch generation with "git diff" without -w/-b
+    option has been significantly optimized.  "git blame" got
+    faster because of the same change.
+
+  - "git log" and "git rev-list" has been optimized
+    significantly when they are used with pathspecs.
+
+  - "git branch --track" can be used to set up configuration
+    variables to help it easier to base your work on branches
+    you track from a remote site.
+
+  - "git format-patch --attach" now emits attachments.  Use
+    --inline to get an inlined multipart/mixed.
+
+  - "git name-rev" learned --refs=<pattern>, to limit the tags
+    used for naming the given revisions only to the ones
+    matching the given pattern.
+
+  - "git remote update" is to run "git fetch" for defined remotes
+    to update tracking branches.
+
+  - "git cvsimport" can now take '-d' to talk with a CVS
+    repository different from what are recorded in CVS/Root
+    (overriding it with environment CVSROOT does not work).
+
+  - "git bundle" can help sneaker-netting your changes between
+    repositories.
+
+  - "git mergetool" can help 3-way file-level conflict
+    resolution with your favorite graphical merge tools.
+
+  - A new configuration "core.symlinks" can be used to disable
+    symlinks on filesystems that do not support them; they are
+    checked out as regular files instead.
+
+  - You can name a commit object with its first line of the
+    message.  The syntax to use is ':/message text'.  E.g.
+
+    $ git show ":/object name: introduce ':/<oneline prefix>' notation"
+
+    means the same thing as:
+
+    $ git show 28a4d940443806412effa246ecc7768a21553ec7
+
+  - "git bisect" learned a new command "run" that takes a script
+    to run after each revision is checked out to determine if it
+    is good or bad, to automate the bisection process.
+
+  - "git log" family learned a new traversal option --first-parent,
+    which does what the name suggests.
+
+
+* Updated behavior of existing commands.
+
+  - "git-merge-recursive" used to barf when there are more than
+    one common ancestors for the merge, and merging them had a
+    rename/rename conflict.  This has been fixed.
+
+  - "git fsck" does not barf on corrupt loose objects.
+
+  - "git rm" does not remove newly added files without -f.
+
+  - "git archimport" allows remapping when coming up with git
+    branch names from arch names.
+
+  - git-svn got almost a rewrite.
+
+  - core.autocrlf configuration, when set to 'true', makes git
+    to convert CRLF at the end of lines in text files to LF when
+    reading from the filesystem, and convert in reverse when
+    writing to the filesystem.  The variable can be set to
+    'input', in which case the conversion happens only while
+    reading from the filesystem but files are written out with
+    LF at the end of lines.  Currently, which paths to consider
+    'text' (i.e. be subjected to the autocrlf mechanism) is
+    decided purely based on the contents, but the plan is to
+    allow users to explicitly override this heuristic based on
+    paths.
+
+  - The behavior of 'git-apply', when run in a subdirectory,
+    without --index nor --cached were inconsistent with that of
+    the command with these options.  This was fixed to match the
+    behavior with --index.  A patch that is meant to be applied
+    with -p1 from the toplevel of the project tree can be
+    applied with any custom -p<n> option.  A patch that is not
+    relative to the toplevel needs to be applied with -p<n>
+    option with or without --index (or --cached).
+
+  - "git diff" outputs a trailing HT when pathnames have embedded
+    SP on +++/--- header lines, in order to help "GNU patch" to
+    parse its output.  "git apply" was already updated to accept
+    this modified output format since ce74618d (Sep 22, 2006).
+
+  - "git cvsserver" runs hooks/update and honors its exit status.
+
+  - "git cvsserver" can be told to send everything with -kb.
+
+  - "git diff --check" also honors the --color output option.
+
+  - "git name-rev" used to stress the fact that a ref is a tag too
+    much, by saying something like "v1.2.3^0~22".  It now says
+    "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
+    not talk about an ancestor of the commit that is tagged, which
+    makes sense).
+
+  - "git rev-list --boundary" now shows boundary markers for the
+    commits omitted by --max-age and --max-count condition.
+
+  - The configuration mechanism now reads $(prefix)/etc/gitconfig.
+
+  - "git apply --verbose" shows what preimage lines were wanted
+    when it couldn't find them.
+
+  - "git status" in a read-only repository got a bit saner.
+
+  - "git fetch" (hence "git clone" and "git pull") are less
+    noisy when the output does not go to tty.
+
+  - "git fetch" between repositories with many refs were slow
+    even when there are not many changes that needed
+    transferring.  This has been sped up by partially rewriting
+    the heaviest parts in C.
+
+  - "git mailinfo" which splits an e-mail into a patch and the
+    meta-information was rewritten, thanks to Don Zickus.  It
+    handles nested multipart better.  The command was broken for
+    a brief period on 'master' branch since 1.5.0 but the
+    breakage is fixed now.
+
+  - send-email learned configurable bcc and chain-reply-to.
+
+  - "git remote show $remote" also talks about branches that
+    would be pushed if you run "git push remote".
+
+  - Using objects from packs is now seriously optimized by clever
+    use of a cache.  This should be most noticeable in git-log
+    family of commands that involve reading many tree objects.
+    In addition, traversing revisions while filtering changes
+    with pathspecs is made faster by terminating the comparison
+    between the trees as early as possible.
+
+
+* Hooks
+
+  - The part to send out notification e-mails was removed from
+    the sample update hook, as it was not an appropriate place
+    to do so.  The proper place to do this is the new post-receive
+    hook.  An example hook has been added to contrib/hooks/.
+
+
+* Others
+
+  - git-revert, git-gc and git-cherry-pick are now built-ins.
+
+Fixes since v1.5.0
+------------------
+
+These are all in v1.5.0.x series.
+
+* Documentation updates
+
+  - Clarifications and corrections to 1.5.0 release notes.
+
+  - The main documentation did not link to git-remote documentation.
+
+  - Clarified introductory text of git-rebase documentation.
+
+  - Converted remaining mentions of update-index on Porcelain
+    documents to git-add/git-rm.
+
+  - Some i18n.* configuration variables were incorrectly
+    described as core.*; fixed.
+
+  - added and clarified core.bare, core.legacyheaders configurations.
+
+  - updated "git-clone --depth" documentation.
+
+  - user-manual updates.
+
+  - Options to 'git remote add' were described insufficiently.
+
+  - Configuration format.suffix was not documented.
+
+  - Other formatting and spelling fixes.
+
+  - user-manual has better cross references.
+
+  - gitweb installation/deployment procedure is now documented.
+
+
+* Bugfixes
+
+  - git-upload-pack closes unused pipe ends; earlier this caused
+    many zombies to hang around.
+
+  - git-rerere was recording the contents of earlier hunks
+    duplicated in later hunks.  This prevented resolving the same
+    conflict when performing the same merge the other way around.
+
+  - git-add and git-update-index on a filesystem on which
+    executable bits are unreliable incorrectly reused st_mode
+    bits even when the path changed between symlink and regular
+    file.
+
+  - git-daemon marks the listening sockets with FD_CLOEXEC so
+    that it won't be leaked into the children.
+
+  - segfault from git-blame when the mandatory pathname
+    parameter was missing was fixed; usage() message is given
+    instead.
+
+  - git-rev-list did not read $GIT_DIR/config file, which means
+    that did not honor i18n.logoutputencoding correctly.
+
+  - Automated merge conflict handling when changes to symbolic
+    links conflicted were completely broken.  The merge-resolve
+    strategy created a regular file with conflict markers in it
+    in place of the symbolic link.  The default strategy,
+    merge-recursive was even more broken.  It removed the path
+    that was pointed at by the symbolic link.  Both of these
+    problems have been fixed.
+
+  - 'git diff maint master next' did not correctly give combined
+    diff across three trees.
+
+  - 'git fast-import' portability fix for Solaris.
+
+  - 'git show-ref --verify' without arguments did not error out
+    but segfaulted.
+
+  - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
+    slashes after a/ and b/.
+
+  - 'git format-patch' produced too long filenames if the commit
+    message had too long line at the beginning.
+
+  - Running 'make all' and then without changing anything
+    running 'make install' still rebuilt some files.  This
+    was inconvenient when building as yourself and then
+    installing as root (especially problematic when the source
+    directory is on NFS and root is mapped to nobody).
+
+  - 'git-rerere' failed to deal with two unconflicted paths that
+    sorted next to each other.
+
+  - 'git-rerere' attempted to open(2) a symlink and failed if
+    there was a conflict.  Since a conflicting change to a
+    symlink would not benefit from rerere anyway, the command
+    now ignores conflicting changes to symlinks.
+
+  - 'git-repack' did not like to pass more than 64 arguments
+    internally to underlying 'rev-list' logic, which made it
+    impossible to repack after accumulating many (small) packs
+    in the repository.
+
+  - 'git-diff' to review the combined diff during a conflicted
+    merge were not reading the working tree version correctly
+    when changes to a symbolic link conflicted.  It should have
+    read the data using readlink(2) but read from the regular
+    file the symbolic link pointed at.
+
+  - 'git-remote' did not like period in a remote's name.
+
+  - 'git.el' honors the commit coding system from the configuration.
+
+  - 'blameview' in contrib/ correctly digs deeper when a line is
+    clicked.
+
+  - 'http-push' correctly makes sure the remote side has leading
+    path.  Earlier it started in the middle of the path, and
+    incorrectly.
+
+  - 'git-merge' did not exit with non-zero status when the
+    working tree was dirty and cannot fast forward.  It does
+    now.
+
+  - 'cvsexportcommit' does not lose yet-to-be-used message file.
+
+  - int-vs-size_t typefix when running combined diff on files
+    over 2GB long.
+
+  - 'git apply --whitespace=strip' should not touch unmodified
+    lines.
+
+  - 'git-mailinfo' choke when a logical header line was too long.
+
+  - 'git show A..B' did not error out.  Negative ref ("not A" in
+    this example) does not make sense for the purpose of the
+    command, so now it errors out.
+
+  - 'git fmt-merge-msg --file' without file parameter did not
+    correctly error out.
+
+  - 'git archimport' barfed upon encountering a commit without
+    summary.
+
+  - 'git index-pack' did not protect itself from getting a short
+    read out of pread(2).
+
+  - 'git http-push' had a few buffer overruns.
+
+  - Build dependency fixes to rebuild fetch.o when other headers
+    change.
+
+  - git.el does not add duplicate sign-off lines.
+
+  - git-commit shows the full stat of the resulting commit, not
+    just about the files in the current directory, when run from
+    a subdirectory.
+
+  - "git-checkout -m '@{8 hours ago}'" had a funny failure from
+    eval; fixed.
+
+  - git-merge (hence git-pull) did not refuse fast-forwarding
+    when the working tree had local changes that would have
+    conflicted with it.
+
+  - a handful small fixes to gitweb.
+
+  - build procedure for user-manual is fixed not to require locally
+    installed stylesheets.
+
+  - "git commit $paths" on paths whose earlier contents were
+    already updated in the index were failing out.
+
+
+* Tweaks
+
+  - sliding mmap() inefficiently mmaped the same region of a
+    packfile with an access pattern that used objects in the
+    reverse order.  This has been made more efficient.

+GIT v1.5.2.1 Release Notes
+==========================
+
+Fixes since v1.5.2
+------------------
+
+* Bugfixes
+
+  - Temporary files that are used when invoking external diff
+    programs did not tolerate a long TMPDIR.
+
+  - git-daemon did not notice when it could not write into its
+    pid file.
+
+  - git-status did not honor core.excludesFile configuration like
+    git-add did.
+
+  - git-annotate did not work from a subdirectory while
+    git-blame did.
+
+  - git-cvsserver should have disabled access to a repository
+    with "gitcvs.pserver.enabled = false" set even when
+    "gitcvs.enabled = true" was set at the same time.  It
+    didn't.
+
+  - git-cvsimport did not work correctly in a repository with
+    its branch heads were packed with pack-refs.
+
+  - ident unexpansion to squash "$Id: xxx $" that is in the
+    repository copy removed incorrect number of bytes.
+
+  - git-svn misbehaved when the subversion repository did not
+    provide MD5 checksums for files.
+
+  - git rebase (and git am) misbehaved on commits that have '\n'
+    (literally backslash and en, not a linefeed) in the title.
+
+  - code to decode base85 used in binary patches had one error
+    return codepath wrong.
+
+  - RFC2047 Q encoding output by git-format-patch used '_' for a
+    space, which is not understood by some programs.  It uses =20
+    which is safer.
+
+  - git-fastimport --import-marks was broken; fixed.
+
+  - A lot of documentation updates, clarifications and fixes.

+GIT v1.5.2.2 Release Notes
+==========================
+
+Fixes since v1.5.2.1
+--------------------
+
+* Usability fix
+
+  - git-gui is shipped with its updated blame interface.  It is
+    rumored that the older one was not just unusable but was
+    active health hazard, but this one is actually pretty.
+    Please see for yourself.
+
+* Bugfixes
+
+  - "git checkout fubar" was utterly confused when there is a
+    branch fubar and a tag fubar at the same time.  It correctly
+    checks out the branch fubar now.
+
+  - "git clone /path/foo" to clone a local /path/foo.git
+    repository left an incorrect configuration.
+
+  - "git send-email" correctly unquotes RFC 2047 quoted names in
+    the patch-email before using their values.
+
+  - We did not accept number of seconds since epoch older than
+    year 2000 as a valid timestamp.  We now interpret positive
+    integers more than 8 digits as such, which allows us to
+    express timestamps more recent than March 1973.
+
+  - git-cvsimport did not work when you have GIT_DIR to point
+    your repository at a nonstandard location.
+
+  - Some systems (notably, Solaris) lack hstrerror() to make
+    h_errno human readable; prepare a replacement
+    implementation.
+
+  - .gitignore file listed git-core.spec but what we generate is
+    git.spec, and nobody noticed for a long time.
+
+  - "git-merge-recursive" does not try to run file level merge
+    on binary files.
+
+  - "git-branch --track" did not create tracking configuration
+    correctly when the branch name had slash in it.
+
+  - The email address of the user specified with user.email
+    configuration was overridden by EMAIL environment variable.
+
+  - The tree parser did not warn about tree entries with
+    nonsense file modes, and assumed they must be blobs.
+
+  - "git log -z" without any other request to generate diff still
+    invoked the diff machinery, wasting cycles.
+
+* Documentation
+
+  - Many updates to fix stale or missing documentation.
+
+  - Although our documentation was primarily meant to be formatted
+    with AsciiDoc7, formatting with AsciiDoc8 is supported better.

+GIT v1.5.2.3 Release Notes
+==========================
+
+Fixes since v1.5.2.2
+--------------------
+
+ * Bugfixes
+
+   - Version 2 pack index format was introduced in version 1.5.2
+     to support pack files that has offset that cannot be
+     represented in 32-bit.  The runtime code to validate such
+     an index mishandled such an index for an empty pack.
+
+   - Commit walkers (most notably, fetch over http protocol)
+     tried to traverse commit objects contained in trees (aka
+     subproject); they shouldn't.
+
+   - A build option NO_R_TO_GCC_LINKER was not explained in Makefile
+     comment correctly.
+
+ * Documentation Fixes and Updates
+
+   - git-config --regexp was not documented properly.
+
+   - git-repack -a was not documented properly.
+
+   - git-remote -n was not documented properly.

+GIT v1.5.2 Release Notes
+========================
+
+Updates since v1.5.1
+--------------------
+
+* Plumbing level superproject support.
+
+  You can include a subdirectory that has an independent git
+  repository in your index and tree objects of your project
+  ("superproject").  This plumbing (i.e. "core") level
+  superproject support explicitly excludes recursive behaviour.
+
+  The "subproject" entries in the index and trees of a superproject
+  are incompatible with older versions of git.  Experimenting with
+  the plumbing level support is encouraged, but be warned that
+  unless everybody in your project updates to this release or
+  later, using this feature would make your project
+  inaccessible by people with older versions of git.
+
+* Plumbing level gitattributes support.
+
+  The gitattributes mechanism allows you to add 'attributes' to
+  paths in your project, and affect the way certain git
+  operations work.  Currently you can influence if a path is
+  considered a binary or text (the former would be treated by
+  'git diff' not to produce textual output; the latter can go
+  through the line endings conversion process in repositories
+  with core.autocrlf set), expand and unexpand '$Id$' keyword
+  with blob object name, specify a custom 3-way merge driver,
+  and specify a custom diff driver.  You can also apply
+  arbitrary filter to contents on check-in/check-out codepath
+  but this feature is an extremely sharp-edged razor and needs
+  to be handled with caution (do not use it unless you
+  understand the earlier mailing list discussion on keyword
+  expansion).  These conversions apply when checking files in
+  or out, and exporting via git-archive.
+
+* The packfile format now optionally supports 64-bit index.
+
+  This release supports the "version 2" format of the .idx
+  file.  This is automatically enabled when a huge packfile
+  needs more than 32-bit to express offsets of objects in the
+  pack.
+
+* Comes with an updated git-gui 0.7.1
+
+* Updated gitweb:
+
+  - can show combined diff for merges;
+  - uses font size of user's preference, not hardcoded in pixels;
+  - can now 'grep';
+
+* New commands and options.
+
+  - "git bisect start" can optionally take a single bad commit and
+    zero or more good commits on the command line.
+
+  - "git shortlog" can optionally be told to wrap its output.
+
+  - "subtree" merge strategy allows another project to be merged in as
+    your subdirectory.
+
+  - "git format-patch" learned a new --subject-prefix=<string>
+    option, to override the built-in "[PATCH]".
+
+  - "git add -u" is a quick way to do the first stage of "git
+    commit -a" (i.e. update the index to match the working
+    tree); it obviously does not make a commit.
+
+  - "git clean" honors a new configuration, "clean.requireforce".  When
+    set to true, this makes "git clean" a no-op, preventing you
+    from losing files by typing "git clean" when you meant to
+    say "make clean".  You can still say "git clean -f" to
+    override this.
+
+  - "git log" family of commands learned --date={local,relative,default}
+    option.  --date=relative is synonym to the --relative-date.
+    --date=local gives the timestamp in local timezone.
+
+* Updated behavior of existing commands.
+
+  - When $GIT_COMMITTER_EMAIL or $GIT_AUTHOR_EMAIL is not set
+    but $EMAIL is set, the latter is used as a substitute.
+
+  - "git diff --stat" shows size of preimage and postimage blobs
+    for binary contents.  Earlier it only said "Bin".
+
+  - "git lost-found" shows stuff that are unreachable except
+    from reflogs.
+
+  - "git checkout branch^0" now detaches HEAD at the tip commit
+    on the named branch, instead of just switching to the
+    branch (use "git checkout branch" to switch to the branch,
+    as before).
+
+  - "git bisect next" can be used after giving only a bad commit
+    without giving a good one (this starts bisection half-way to
+    the root commit).  We used to refuse to operate without a
+    good and a bad commit.
+
+  - "git push", when pushing into more than one repository, does
+    not stop at the first error.
+
+  - "git archive" does not insist you to give --format parameter
+    anymore; it defaults to "tar".
+
+  - "git cvsserver" can use backends other than sqlite.
+
+  - "gitview" (in contrib/ section) learned to better support
+    "git-annotate".
+
+  - "git diff $commit1:$path2 $commit2:$path2" can now report
+    mode changes between the two blobs.
+
+  - Local "git fetch" from a repository whose object store is
+    one of the alternates (e.g. fetching from the origin in a
+    repository created with "git clone -l -s") avoids
+    downloading objects unnecessarily.
+
+  - "git blame" uses .mailmap to canonicalize the author name
+    just like "git shortlog" does.
+
+  - "git pack-objects" pays attention to pack.depth
+    configuration variable.
+
+  - "git cherry-pick" and "git revert" does not use .msg file in
+    the working tree to prepare commit message; instead it uses
+    $GIT_DIR/MERGE_MSG as other commands do.
+
+* Builds
+
+  - git-p4import has never been installed; now there is an
+    installation option to do so.
+
+  - gitk and git-gui can be configured out.
+
+  - Generated documentation pages automatically get version
+    information from GIT_VERSION.
+
+  - Parallel build with "make -j" descending into subdirectory
+    was fixed.
+
+* Performance Tweaks
+
+  - Optimized "git-rev-list --bisect" (hence "git-bisect").
+
+  - Optimized "git-add $path" in a large directory, most of
+    whose contents are ignored.
+
+  - Optimized "git-diff-tree" for reduced memory footprint.
+
+  - The recursive merge strategy updated a worktree file that
+    was changed identically in two branches, when one of them
+    renamed it.  We do not do that when there is no rename, so
+    match that behaviour.  This avoids excessive rebuilds.
+
+  - The default pack depth has been increased to 50, as the
+    recent addition of delta_base_cache makes deeper delta chains
+    much less expensive to access.  Depending on the project, it was
+    reported that this reduces the resulting pack file by 10%
+    or so.
+
+
+Fixes since v1.5.1
+------------------
+
+All of the fixes in v1.5.1 maintenance series are included in
+this release, unless otherwise noted.
+
+* Bugfixes
+
+  - Switching branches with "git checkout" refused to work when
+    a path changes from a file to a directory between the
+    current branch and the new branch, in order not to lose
+    possible local changes in the directory that is being turned
+    into a file with the switch.  We now allow such a branch
+    switch after making sure that there is no locally modified
+    file nor un-ignored file in the directory.  This has not
+    been backported to 1.5.1.x series, as it is rather an
+    intrusive change.
+
+  - Merging branches that have a file in one and a directory in
+    another at the same path used to get quite confused.  We
+    handle such a case a bit more carefully, even though that is
+    still left as a conflict for the user to sort out.  This
+    will not be backported to 1.5.1.x series, as it is rather an
+    intrusive change.
+
+  - git-fetch had trouble with a remote with insanely large number
+    of refs.
+
+  - "git clean -d -X" now does not remove non-excluded directories.
+
+  - rebasing (without -m) a series that changes a symlink to a directory
+    in the middle of a path confused git-apply greatly and refused to
+    operate.

+==========================
+
+Fixes since v1.5.3
+------------------
+
+This is solely to fix the generated RPM's dependencies.  We used
+to have git-p4 package but we do not anymore.  As suggested on
+the mailing list, this release makes git-core "Obsolete" git-p4,
+so that yum update would not complain.

+GIT v1.5.3.2 Release Notes
+==========================
+
+Fixes since v1.5.3.1
+--------------------
+
+ * git-push sent thin packs by default, which was not good for
+   the public distribution server (no point in saving transfer
+   while pushing; no point in making the resulting pack less
+   optimum).
+
+ * git-svn sometimes terminated with "Malformed network data" when
+   talking over svn:// protocol.
+
+ * git-send-email re-issued the same message-id about 10% of the
+   time if you fired off 30 messages within a single second.
+
+ * git-stash was not terminating the log message of commits it
+   internally creates with LF.
+
+ * git-apply failed to check the size of the patch hunk when its
+   beginning part matched the remainder of the preimage exactly,
+   even though the preimage recorded in the hunk was much larger
+   (therefore the patch should not have applied), leading to a
+   segfault.
+
+ * "git rm foo && git commit foo" complained that 'foo' needs to
+   be added first, instead of committing the removal, which was a
+   nonsense.
+
+ * git grep -c said "/dev/null: 0".
+
+ * git-add -u failed to recognize a blob whose type changed
+   between the index and the work tree.
+
+ * The limit to rename detection has been tightened a lot to
+   reduce performance problems with a huge change.
+
+ * cvsimport and svnimport barfed when the input tried to move
+   a tag.
+
+ * "git apply -pN" did not chop the right number of directories.
+
+ * "git svnimport" did not like SVN tags with funny characters in them.
+
+ * git-gui 0.8.3, with assorted fixes, including:
+
+   - font-chooser on X11 was unusable with large number of fonts;
+   - a diff that contained a deleted symlink made it barf;
+   - an untracked symbolic link to a directory made it fart;
+   - a file with % in its name made it vomit;
+
+
+Documentation updates
+---------------------
+
+User manual has been somewhat restructured.  I think the new
+organization is much easier to read.

+GIT v1.5.3 Release Notes
+========================
+
+Updates since v1.5.2
+--------------------
+
+* The commit walkers other than http are officially deprecated,
+  but still supported for now.
+
+* The submodule support has Porcelain layer.
+
+  Note that the current submodule support is minimal and this is
+  deliberately so.  A design decision we made is that operations
+  at the supermodule level do not recurse into submodules by
+  default.  The expectation is that later we would add a
+  mechanism to tell git which submodules the user is interested
+  in, and this information might be used to determine the
+  recursive behaviour of certain commands (e.g. "git checkout"
+  and "git diff"), but currently we haven't agreed on what that
+  mechanism should look like.  Therefore, if you use submodules,
+  you would probably need "git submodule update" on the
+  submodules you care about after running a "git checkout" at
+  the supermodule level.
+
+* There are a handful pack-objects changes to help you cope better
+  with repositories with pathologically large blobs in them.
+
+* For people who need to import from Perforce, a front-end for
+  fast-import is in contrib/fast-import/.
+
+* Comes with git-gui 0.8.2.
+
+* Comes with updated gitk.
+
+* New commands and options.
+
+  - "git log --date=<format>" can use more formats: iso8601, rfc2822.
+
+  - The hunk header output from "git diff" family can be customized
+    with the attributes mechanism.  See gitattributes(5) for details.
+
+  - "git stash" allows you to quickly save away your work in
+    progress and replay it later on an updated state.
+
+  - "git rebase" learned an "interactive" mode that let you
+    pick and reorder which commits to rebuild.
+
+  - "git fsck" can save its findings in $GIT_DIR/lost-found, without a
+    separate invocation of "git lost-found" command.  The blobs stored by
+    lost-found are stored in plain format to allow you to grep in them.
+
+  - $GIT_WORK_TREE environment variable can be used together with
+    $GIT_DIR to work in a subdirectory of a working tree that is
+    not located at "$GIT_DIR/..".
+
+  - Giving "--file=<file>" option to "git config" is the same as
+    running the command with GIT_CONFIG=<file> environment.
+
+  - "git log" learned a new option "--follow", to follow
+    renaming history of a single file.
+
+  - "git filter-branch" lets you rewrite the revision history of
+    specified branches. You can specify a number of filters to
+    modify the commits, files and trees.
+
+  - "git cvsserver" learned new options (--base-path, --export-all,
+    --strict-paths) inspired by "git daemon".
+
+  - "git daemon --base-path-relaxed" can help migrating a repository URL
+    that did not use to use --base-path to use --base-path.
+
+  - "git commit" can use "-t templatefile" option and commit.template
+    configuration variable to prime the commit message given to you in the
+    editor.
+
+  - "git submodule" command helps you manage the projects from
+    the superproject that contain them.
+
+  - In addition to core.compression configuration option,
+    core.loosecompression and pack.compression options can
+    independently tweak zlib compression levels used for loose
+    and packed objects.
+
+  - "git ls-tree -l" shows size of blobs pointed at by the
+    tree entries, similar to "/bin/ls -l".
+
+  - "git rev-list" learned --regexp-ignore-case and
+    --extended-regexp options to tweak its matching logic used
+    for --grep filtering.
+
+  - "git describe --contains" is a handier way to call more
+    obscure command "git name-rev --tags".
+
+  - "git gc --aggressive" tells the command to spend more cycles
+    to optimize the repository harder.
+
+  - "git repack" learned a "window-memory" limit which
+    dynamically reduces the window size to stay within the
+    specified memory usage.
+
+  - "git repack" can be told to split resulting packs to avoid
+    exceeding limit specified with "--max-pack-size".
+
+  - "git fsck" gained --verbose option.  This is really really
+    verbose but it might help you identify exact commit that is
+    corrupt in your repository.
+
+  - "git format-patch" learned --numbered-files option.  This
+    may be useful for MH users.
+
+  - "git format-patch" learned format.subjectprefix configuration
+    variable, which serves the same purpose as "--subject-prefix"
+    option.
+
+  - "git tag -n -l" shows tag annotations while listing tags.
+
+  - "git cvsimport" can optionally use the separate-remote layout.
+
+  - "git blame" can be told to see through commits that change
+    whitespaces and indentation levels with "-w" option.
+
+  - "git send-email" can be told not to thread the messages when
+    sending out more than one patches.
+
+  - "git send-email" can also be told how to find whom to cc the
+    message to for each message via --cc-cmd.
+
+  - "git config" learned NUL terminated output format via -z to
+    help scripts.
+
+  - "git add" learned "--refresh <paths>..." option to selectively refresh
+    the cached stat information.
+
+  - "git init -q" makes the command quieter.
+
+  - "git -p command" now has a cousin of opposite sex, "git --no-pager
+    command".
+
+* Updated behavior of existing commands.
+
+  - "gitweb" can offer multiple snapshot formats.
+
+    ***NOTE*** Unfortunately, this changes the format of the
+    $feature{snapshot}{default} entry in the per-site
+    configuration file 'gitweb_config.perl'.  It used to be a
+    three-element tuple that describe a single format; with the
+    new configuration item format, you only have to say the name
+    of the format ('tgz', 'tbz2' or 'zip').  Please update the
+    your configuration file accordingly.
+
+  - "git clone" uses -l (hardlink files under .git) by default when
+    cloning locally.
+
+  - URL used for "git clone" and friends can specify nonstandard SSH port
+    by using ssh://host:port/path/to/repo syntax.
+
+  - "git bundle create" can now create a bundle without negative refs,
+    i.e. "everything since the beginning up to certain points".
+
+  - "git diff" (but not the plumbing level "git diff-tree") now
+    recursively descends into trees by default.
+
+  - "git diff" does not show differences that come only from
+    stat-dirtiness in the form of "diff --git" header anymore.
+    It runs "update-index --refresh" silently as needed.
+
+  - "git tag -l" used to match tags by globbing its parameter as if it
+    has wildcard '*' on both ends, which made "git tag -l gui" to match
+    tag 'gitgui-0.7.0'; this was very annoying.  You now have to add
+    asterisk on the sides you want to wildcard yourself.
+
+  - The editor to use with many interactive commands can be
+    overridden with GIT_EDITOR environment variable, or if it
+    does not exist, with core.editor configuration variable.  As
+    before, if you have neither, environment variables VISUAL
+    and EDITOR are consulted in this order, and then finally we
+    fall back on "vi".
+
+  - "git rm --cached" does not complain when removing a newly
+    added file from the index anymore.
+
+  - Options to "git log" to affect how --grep/--author options look for
+    given strings now have shorter abbreviations.  -i is for ignore case,
+    and -E is for extended regexp.
+
+  - "git log" learned --log-size to show the number of bytes in
+    the log message part of the output to help qgit.
+
+  - "git log --name-status" does not require you to give "-r" anymore.
+    As a general rule, Porcelain commands should recurse when showing
+    diff.
+
+  - "git format-patch --root A" can be used to format everything
+    since the beginning up to A.  This was supported with
+    "git format-patch --root A A" for a long time, but was not
+    properly documented.
+
+  - "git svn dcommit" retains local merge information.
+
+  - "git svnimport" allows an empty string to be specified as the
+    trunk/ directory.  This is necessary to suck data from a SVN
+    repository that doe not have trunk/ branches/ and tags/ organization
+    at all.
+
+  - "git config" to set values also honors type flags like --bool
+    and --int.
+
+  - core.quotepath configuration can be used to make textual git
+    output to emit most of the characters in the path literally.
+
+  - "git mergetool" chooses its backend more wisely, taking
+    notice of its environment such as use of X, Gnome/KDE, etc.
+
+  - "gitweb" shows merge commits a lot nicer than before.  The
+    default view uses more compact --cc format, while the UI
+    allows to choose normal diff with any parent.
+
+  - snapshot files "gitweb" creates from a repository at
+    $path/$project/.git are more useful.  We use $project part
+    in the filename, which we used to discard.
+
+  - "git cvsimport" creates lightweight tags; there is no
+    interesting information we can record in an annotated tag,
+    and the handcrafted ones the old code created was not
+    properly formed anyway.
+
+  - "git push" pretends that you immediately fetched back from
+    the remote by updating corresponding remote tracking
+    branches if you have any.
+
+  - The diffstat given after a merge (or a pull) honors the
+    color.diff configuration.
+
+  - "git commit --amend" is now compatible with various message source
+    options such as -m/-C/-c/-F.
+
+  - "git apply --whitespace=strip" removes blank lines added at
+    the end of the file.
+
+  - "git fetch" over git native protocols with "-v" option shows
+    connection status, and the IP address of the other end, to
+    help diagnosing problems.
+
+  - We used to have core.legacyheaders configuration, when
+    set to false, allowed git to write loose objects in a format
+    that mimics the format used by objects stored in packs.  It
+    turns out that this was not so useful.  Although we will
+    continue to read objects written in that format, we do not
+    honor that configuration anymore and create loose objects in
+    the legacy/traditional format.
+
+  - "--find-copies-harder" option to diff family can now be
+    spelled as "-C -C" for brevity.
+
+  - "git mailsplit" (hence "git am") can read from Maildir
+    formatted mailboxes.
+
+  - "git cvsserver" does not barf upon seeing "cvs login"
+    request.
+
+  - "pack-objects" honors "delta" attribute set in
+    .gitattributes.  It does not attempt to deltify blobs that
+    come from paths with delta attribute set to false.
+
+  - "new-workdir" script (in contrib) can now be used with a
+    bare repository.
+
+  - "git mergetool" learned to use gvimdiff.
+
+  - "gitview" (in contrib) has a better blame interface.
+
+  - "git log" and friends did not handle a commit log message
+    that is larger than 16kB; they do now.
+
+  - "--pretty=oneline" output format for "git log" and friends
+    deals with "malformed" commit log messages that have more
+    than one lines in the first paragraph better.  We used to
+    show the first line, cutting the title at mid-sentence; we
+    concatenate them into a single line and treat the result as
+    "oneline".
+
+  - "git p4import" has been demoted to contrib status.  For
+    a superior option, checkout the "git p4" front end to
+    "git fast-import" (also in contrib).  The man page and p4
+    rpm have been removed as well.
+
+  - "git mailinfo" (hence "am") now tries to see if the message
+    is in utf-8 first, instead of assuming iso-8859-1, if
+    incoming e-mail does not say what encoding it is in.
+
+* Builds
+
+  - old-style function definitions (most notably, a function
+    without parameter defined with "func()", not "func(void)")
+    have been eradicated.
+
+  - "git tag" and "git verify-tag" have been rewritten in C.
+
+* Performance Tweaks
+
+  - "git pack-objects" avoids re-deltification cost by caching
+    small enough delta results it creates while looking for the
+    best delta candidates.
+
+  - "git pack-objects" learned a new heuristic to prefer delta
+    that is shallower in depth over the smallest delta
+    possible.  This improves both overall packfile access
+    performance and packfile density.
+
+  - diff-delta code that is used for packing has been improved
+    to work better on big files.
+
+  - when there are more than one pack files in the repository,
+    the runtime used to try finding an object always from the
+    newest packfile; it now tries the same packfile as we found
+    the object requested the last time, which exploits the
+    locality of references.
+
+  - verifying pack contents done by "git fsck --full" got boost
+    by carefully choosing the order to verify objects in them.
+
+  - "git read-tree -m" to read into an already populated index
+    has been optimized vastly.  The effect of this can be seen
+    when switching branches that have differences in only a
+    handful paths.
+
+  - "git add paths..." and "git commit paths..." has also been
+    heavily optimized.
+
+Fixes since v1.5.2
+------------------
+
+All of the fixes in v1.5.2 maintenance series are included in
+this release, unless otherwise noted.
+
+* Bugfixes
+
+  - "gitweb" had trouble handling non UTF-8 text with older
+    Encode.pm Perl module.
+
+  - "git svn" misparsed the data from the commits in the repository when
+    the user had "color.diff = true" in the configuration.  This has been
+    fixed.
+
+  - There was a case where "git svn dcommit" clobbered changes made on the
+    SVN side while committing multiple changes.
+
+  - "git-write-tree" had a bad interaction with racy-git avoidance and
+    gitattributes mechanisms.
+
+  - "git --bare command" overrode existing GIT_DIR setting and always
+    made it treat the current working directory as GIT_DIR.
+
+  - "git ls-files --error-unmatch" does not complain if you give the
+    same path pattern twice by mistake.
+
+  - "git init" autodetected core.filemode but not core.symlinks, which
+    made a new directory created automatically by "git clone" cumbersome
+    to use on filesystems that require these configurations to be set.
+
+  - "git log" family of commands behaved differently when run as "git
+    log" (no pathspec) and as "git log --" (again, no pathspec).  This
+    inconsistency was introduced somewhere in v1.3.0 series but now has
+    been corrected.
+
+  - "git rebase -m" incorrectly displayed commits that were skipped.

+GIT v1.5.4.3 Release Notes
+==========================
+
+Fixes since v1.5.4.2
+--------------------
+
+ * RPM spec used to pull in everything with 'git'.  This has been

+   This should match end user's expectation better.
+
+ * When some refs failed to update, git-push reported "failure"
+   which was unclear if some other refs were updated or all of
+   them failed atomically (the answer is the former).  Reworded
+   the message to clarify this.
+
+ * "git clone" from a repository whose HEAD was misconfigured
+   did not set up the remote properly.  Now it tries to do
+   better.
+
+ * Updated git-push documentation to clarify what "matching"
+   means, in order to reduce user confusion.
+
+ * Updated git-add documentation to clarify "add -u" operates in
+   the current subdirectory you are in, just like other commands.
+
+ * git-gui updates to work on OSX and Windows better.

+GIT v1.5.4.4 Release Notes
+==========================
+
+Fixes since v1.5.4.3
+--------------------
+
+ * Building and installing with an overtight umask such as 077 made
+   installed templates unreadable by others, while the rest of the install
+   are done in a way that is friendly to umask 022.
+
+ * "git cvsexportcommit -w $cvsdir" misbehaved when GIT_DIR is set to a
+   relative directory.
+
+ * "git http-push" had an invalid memory access that could lead it to
+   segfault.
+
+ * When "git rebase -i" gave control back to the user for a commit that is
+   marked to be edited, it just said "modify it with commit --amend",
+   without saying what to do to continue after modifying it.  Give an
+   explicit instruction to run "rebase --continue" to be more helpful.
+
+ * "git send-email" in 1.5.4.3 issued a bogus empty In-Reply-To: header.
+
+ * "git bisect" showed mysterious "won't bisect on seeked tree" error message.
+   This was leftover from Cogito days to prevent "bisect" starting from a
+   cg-seeked state.  We still keep the Cogito safety, but running "git bisect
+   start" when another bisect was in effect will clean up and start over.
+
+ * "git push" with an explicit PATH to receive-pack did not quite work if
+   receive-pack was not on usual PATH.  We earlier fixed the same issue
+   with "git fetch" and upload-pack, but somehow forgot to do so in the
+   other direction.
+
+ * git-gui's info dialog was not displayed correctly when the user tries
+   to commit nothing (i.e. without staging anything).
+
+ * "git revert" did not properly fail when attempting to run with a
+   dirty index.
+
+ * "git merge --no-commit --no-ff <other>" incorrectly made commits.
+
+ * "git merge --squash --no-ff <other>", which is a nonsense combination
+   of options, was not rejected.
+
+ * "git ls-remote" and "git remote show" against an empty repository
+   failed, instead of just giving an empty result (regression).
+
+ * "git fast-import" did not handle a renamed path whose name needs to be
+   quoted, due to a bug in unquote_c_style() function.
+
+ * "git cvsexportcommit" was confused when multiple files with the same
+   basename needed to be pushed out in the same commit.
+
+ * "git daemon" did not send early errors to syslog.
+
+ * "git log --merge" did not work well with --left-right option.
+
+ * "git svn" prompted for client cert password every time it accessed the
+   server.
+
+ * The reset command in "git fast-import" data stream was documented to
+   end with an optional LF, but it actually required one.
+
+ * "git svn dcommit/rebase" did not honor --rewrite-root option.
+
+Also included are a handful documentation updates.

+GIT v1.5.4.5 Release Notes
+==========================
+
+Fixes since v1.5.4.4
+--------------------
+
+ * "git fetch there" when the URL information came from the Cogito style
+   branches/there file did not update refs/heads/there (regression in
+   1.5.4).
+
+ * Bogus refspec configuration such as "remote.there.fetch = =" were not
+   detected as errors (regression in 1.5.4).
+
+ * You couldn't specify a custom editor whose path contains a whitespace
+   via GIT_EDITOR (and core.editor).
+
+ * The subdirectory filter to "git filter-branch" mishandled a history
+   where the subdirectory becomes empty and then later becomes non-empty.
+
+ * "git shortlog" gave an empty line if the original commit message was
+   malformed (e.g. a botched import from foreign SCM).  Now it finds the
+   first non-empty line and uses it for better information.
+
+ * When the user fails to give a revision parameter to "git svn", an error
+   from the Perl interpreter was issued because the script lacked proper
+   error checking.
+
+ * After "git rebase" stopped due to conflicts, if the user played with
+   "git reset" and friends, "git rebase --abort" failed to go back to the
+   correct commit.
+
+ * Additional work trees prepared with git-new-workdir (in contrib/) did
+   not share git-svn metadata directory .git/svn with the original.
+
+ * "git-merge-recursive" did not mark addition of the same path with
+   different filemodes correctly as a conflict.
+
+ * "gitweb" gave malformed URL when pathinfo stype paths are in use.
+
+ * "-n" stands for "--no-tags" again for "git fetch".
+
+ * "git format-patch" did not detect the need to add 8-bit MIME header
+   when the user used format.header configuration.
+
+ * "rev~" revision specifier used to mean "rev", which was inconsistent
+   with how "rev^" worked.  Now "rev~" is the same as "rev~1" (hence it
+   also is the same as "rev^1"), and "rev~0" is the same as "rev^0"
+   (i.e. it has to be a commit).
+
+ * "git quiltimport" did not grok empty lines, lines in "file -pNNN"
+   format to specify the prefix levels and lines with trailing comments.
+
+ * "git rebase -m" triggered pre-commit verification, which made
+   "rebase --continue" impossible.
+
+As usual, it also comes with many documentation fixes and clarifications.

+GIT v1.5.4.6 Release Notes
+==========================
+
+I personally do not think there is any reason anybody should want to
+run v1.5.4.X series these days, because 'master' version is always
+more stable than any tagged released version of git.
+
+This is primarily to futureproof "git-shell" to accept requests
+without a dash between "git" and subcommand name (e.g. "git
+upload-pack") which the newer client will start to make sometime in
+the future.
+
+Fixes since v1.5.4.5
+--------------------
+
+ * Command line option "-n" to "git-repack" was not correctly parsed.
+
+ * Error messages from "git-apply" when the patchfile cannot be opened
+   have been improved.
+
+ * Error messages from "git-bisect" when given nonsense revisions have
+   been improved.
+
+ * reflog syntax that uses time e.g. "HEAD@{10 seconds ago}:path" did not
+   stop parsing at the closing "}".
+
+ * "git rev-parse --symbolic-full-name ^master^2" printed solitary "^",
+   but it should print nothing.
+
+ * "git apply" did not enforce "match at the beginning" correctly.
+
+ * a path specification "a/b" in .gitattributes file should not match
+   "sub/a/b", but it did.
+
+ * "git log --date-order --topo-order" did not override the earlier
+   date-order with topo-order as expected.
+
+ * "git fast-export" did not export octopus merges correctly.
+
+ * "git archive --prefix=$path/" mishandled gitattributes.
+
+As usual, it also comes with many documentation fixes and clarifications.

+==========================
+
+Fixes since 1.5.4.7
+-------------------
+
+ * Removed support for an obsolete gitweb request URI, whose
+   implementation ran "git diff" Porcelain, instead of using plumbing,
+   which would have run an external diff command specified in the
+   repository configuration as the gitweb user.

+GIT v1.5.4 Release Notes
+========================
+
+Removal
+-------
+
+ * "git svnimport" was removed in favor of "git svn".  It is still there
+   in the source tree (contrib/examples) but unsupported.
+
+ * As git-commit and git-status have been rewritten, "git runstatus"
+   helper script lost all its users and has been removed.
+
+
+Temporarily disabled
+--------------------
+
+ * "git http-push" is known not to work well with cURL library older
+   than 7.16, and we had reports of repository corruption.  It is
+   disabled on such platforms for now.  Unfortunately, 1.5.3.8 shares
+   the same issue.  In other words, this does not mean you will be
+   fine if you stick to an older git release.  For now, please do not
+   use http-push from older git with cURL older than 7.16 if you
+   value your data. A proper fix will hopefully materialize in
+   later versions.
+
+
+Deprecation notices
+-------------------
+
+ * From v1.6.0, git will by default install dashed form of commands
+   (e.g. "git-commit") outside of users' normal $PATH, and will install
+   only selected commands ("git" itself, and "gitk") in $PATH.  This
+   implies:
+
+   - Using dashed forms of git commands (e.g. "git-commit") from the
+     command line has been informally deprecated since early 2006, but
+     now it officially is, and will be removed in the future.  Use
+     dash-less forms (e.g. "git commit") instead.
+
+   - Using dashed forms from your scripts, without first prepending the
+     return value from "git --exec-path" to the scripts' PATH, has been
+     informally deprecated since early 2006, but now it officially is.
+
+   - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
+     PATH" early in your script is not deprecated with this change.
+
+   Users are strongly encouraged to adjust their habits and scripts now
+   to prepare for this change.
+
+ * The post-receive hook was introduced in March 2007 to supersede
+   the post-update hook, primarily to overcome the command line length
+   limitation of the latter.  Use of post-update hook will be deprecated
+   in future versions of git, starting from v1.6.0.
+
+ * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
+   option, and will be removed in the future.
+
+ * "git peek-remote" is deprecated, as "git ls-remote" was written in C
+   and works for all transports; "git peek-remote" will be removed in
+   the future.
+
+ * "git repo-config" which was an old name for "git config" command
+   has been supported without being advertised for a long time.  The
+   next feature release will remove it.
+
+ * From v1.6.0, the repack.usedeltabaseoffset config option will default
+   to true, which will give denser packfiles (i.e. more efficient storage).
+   The downside is that git older than version 1.4.4 will not be able
+   to directly use a repository packed using this setting.
+
+ * From v1.6.0, the pack.indexversion config option will default to 2,
+   which is slightly more efficient, and makes repacking more immune to
+   data corruptions.  Git older than version 1.5.2 may revert to version 1
+   of the pack index with a manual "git index-pack" to be able to directly
+   access corresponding pack files.
+
+
+Updates since v1.5.3
+--------------------
+
+ * Comes with much improved gitk, with i18n.
+
+ * Comes with git-gui 0.9.2 with i18n.
+
+ * gitk is now merged as a subdirectory of git.git project, in
+   preparation for its i18n.
+
+ * progress displays from many commands are a lot nicer to the eye.
+   Transfer commands show throughput data.
+
+ * many commands that pay attention to per-directory .gitignore now do
+   so lazily, which makes the usual case go much faster.
+
+ * Output processing for '--pretty=format:<user format>' has been
+   optimized.
+
+ * Rename detection of diff family while detecting exact matches has
+   been greatly optimized.
+
+ * Rename detection of diff family tries to make more natural looking
+   pairing.  Earlier, if multiple identical rename sources were
+   found in the preimage, the source used was picked pretty much at random.
+
+ * Value "true" for color.diff and color.status configuration used to
+   mean "always" (even when the output is not going to a terminal).
+   This has been corrected to mean the same thing as "auto".
+
+ * "git diff" Porcelain now respects diff.external configuration, which
+   is another way to specify GIT_EXTERNAL_DIFF.
+
+ * "git diff" can be told to use different prefixes other than
+   "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".
+
+ * "git diff" sometimes did not quote paths with funny
+   characters properly.
+
+ * "git log" (and any revision traversal commands) misbehaved
+   when --diff-filter is given but was not asked to actually
+   produce diff.
+
+ * HTTP proxy can be specified per remote repository using
+   remote.*.httpproxy configuration, or global http.proxy configuration
+   variable.
+
+ * Various Perforce importer updates.
+
+ * Example update and post-receive hooks have been improved.
+
+ * Any command that wants to take a commit object name can now use
+   ":/string" syntax to name a commit.
+
+ * "git reset" is now built-in and its output can be squelched with -q.
+
+ * "git reset --hard" does not make any sense in a bare
+   repository, but did not error out; fixed.
+
+ * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
+
+ * "git rebase" learned --whitespace option.
+
+ * In "git rebase", when you decide not to replay a particular change
+   after the command stopped with a conflict, you can say "git rebase
+   --skip" without first running "git reset --hard", as the command now
+   runs it for you.
+
+ * "git rebase --interactive" mode can now work on detached HEAD.
+
+ * Other minor to serious bugs in "git rebase -i" have been fixed.
+
+ * "git rebase" now detaches head during its operation, so after a
+   successful "git rebase" operation, the reflog entry branch@{1} for
+   the current branch points at the commit before the rebase was
+   started.
+
+ * "git rebase -i" also triggers rerere to help your repeated merges.
+
+ * "git merge" can call the "post-merge" hook.
+
+ * "git pack-objects" can optionally run deltification with multiple
+   threads.
+
+ * "git archive" can optionally substitute keywords in files marked with
+   export-subst attribute.
+
+ * "git cherry-pick" made a misguided attempt to repeat the original
+   command line in the generated log message, when told to cherry-pick a
+   commit by naming a tag that points at it.  It does not anymore.
+
+ * "git for-each-ref" learned %(xxxdate:<date-format>) syntax to show the
+   various date fields in different formats.
+
+ * "git gc --auto" is a low-impact way to automatically run a variant of
+   "git repack" that does not lose unreferenced objects (read: safer
+   than the usual one) after the user accumulates too many loose
+   objects.
+
+ * "git clean" has been rewritten in C.
+
+ * You need to explicitly set clean.requireForce to "false" to allow
+   "git clean" without -f to do any damage (lack of the configuration
+   variable used to mean "do not require -f option to lose untracked
+   files", but we now use the safer default).
+
+ * The kinds of whitespace errors "git diff" and "git apply" notice (and
+   fix) can be controlled via 'core.whitespace' configuration variable
+   and 'whitespace' attribute in .gitattributes file.
+
+ * "git push" learned --dry-run option to show what would happen if a
+   push is run.
+
+ * "git push" does not update a tracking ref on the local side when the
+   remote refused to update the corresponding ref.
+
+ * "git push" learned --mirror option.  This is to push the local refs
+   one-to-one to the remote, and deletes refs from the remote that do
+   not exist anymore in the repository on the pushing side.
+
+ * "git push" can remove a corrupt ref at the remote site with the usual
+   ":ref" refspec.
+
+ * "git remote" knows --mirror mode.  This is to set up configuration to
+   push into a remote repository to store local branch heads to the same
+   branch on the remote side, and remove branch heads locally removed
+   from local repository at the same time.  Suitable for pushing into a
+   back-up repository.
+
+ * "git remote" learned "rm" subcommand.
+
+ * "git cvsserver" can be run via "git shell".  Also, "cvs" is
+   recognized as a synonym for "git cvsserver", so that CVS users
+   can be switched to git just by changing their login shell.
+
+ * "git cvsserver" acts more like receive-pack by running post-receive
+   and post-update hooks.
+
+ * "git am" and "git rebase" are far less verbose.
+
+ * "git pull" learned to pass --[no-]ff option to underlying "git
+   merge".
+
+ * "git pull --rebase" is a different way to integrate what you fetched
+   into your current branch.
+
+ * "git fast-export" produces data-stream that can be fed to fast-import
+   to reproduce the history recorded in a git repository.
+
+ * "git add -i" takes pathspecs to limit the set of files to work on.
+
+ * "git add -p" is a short-hand to go directly to the selective patch
+   subcommand in the interactive command loop and to exit when done.
+
+ * "git add -i" UI has been colorized.  The interactive prompt
+   and menu can be colored by setting color.interactive
+   configuration.  The diff output (including the hunk picker)
+   are colored with color.diff configuration.
+
+ * "git commit --allow-empty" allows you to create a single-parent
+   commit that records the same tree as its parent, overriding the usual
+   safety valve.
+
+ * "git commit --amend" can amend a merge that does not change the tree
+   from its first parent.
+
+ * "git commit" used to unconditionally strip comment lines that
+   began with '#' and removed excess blank lines.  This behavior has
+   been made configurable.
+
+ * "git commit" has been rewritten in C.
+
+ * "git stash random-text" does not create a new stash anymore.  It was
+   a UI mistake.  Use "git stash save random-text", or "git stash"
+   (without extra args) for that.
+
+ * "git stash clear extra-text" does not clear the whole stash
+   anymore.  It is tempting to expect "git stash clear stash@{2}"
+   to drop only a single named stash entry, and it is rude to
+   discard everything when that is asked (but not provided).
+
+ * "git prune --expire <time>" can exempt young loose objects from
+   getting pruned.
+
+ * "git branch --contains <commit>" can list branches that are
+   descendants of a given commit.
+
+ * "git log" learned --early-output option to help interactive GUI
+   implementations.
+
+ * "git bisect" learned "skip" action to mark untestable commits.
+
+ * "git bisect visualize" learned a shorter synonym "git bisect view".
+
+ * "git bisect visualize" runs "git log" in a non-windowed
+   environments.  It also can be told what command to run (e.g. "git
+   bisect visualize tig").
+
+ * "git format-patch" learned "format.numbered" configuration variable
+   to automatically turn --numbered option on when more than one commits
+   are formatted.
+
+ * "git ls-files" learned "--exclude-standard" to use the canned set of
+   exclude files.
+
+ * "git tag -a -f existing" begins the editor session using the existing
+   annotation message.
+
+ * "git tag -m one -m bar" (multiple -m options) behaves similarly to
+   "git commit"; the parameters to -m options are formatted as separate
+   paragraphs.
+
+ * The format "git show" outputs an annotated tag has been updated to
+   include "Tagger: " and "Date: " lines from the tag itself.  Strictly
+   speaking this is a backward incompatible change, but this is a
+   reasonable usability fix and people's scripts shouldn't have been
+   relying on the exact output from "git show" Porcelain anyway.
+
+ * "git cvsimport" did not notice errors from underlying "cvsps"
+   and produced a corrupt import silently.
+
+ * "git cvsexportcommit" learned -w option to specify and switch to the
+   CVS working directory.
+
+ * "git checkout" from a subdirectory learned to use "../path" to allow
+   checking out a path outside the current directory without cd'ing up.
+
+ * "git checkout" from and to detached HEAD leaves a bit more
+   information in the reflog.
+
+ * "git send-email --dry-run" shows full headers for easier diagnosis.
+
+ * "git merge-ours" is now built-in.
+
+ * "git svn" learned "info" and "show-externals" subcommands.
+
+ * "git svn" run from a subdirectory failed to read settings from the
+   .git/config.
+
+ * "git svn" learned --use-log-author option, which picks up more
+   descriptive name from From: and Signed-off-by: lines in the commit
+   message.
+
+ * "git svn" wasted way too much disk to record revision mappings
+   between svn and git; a new representation that is much more compact
+   for this information has been introduced to correct this.
+
+ * "git svn" left temporary index files it used without cleaning them
+   up; this was corrected.
+
+ * "git status" from a subdirectory now shows relative paths, which
+   makes copy-and-pasting for git-checkout/git-add/git-rm easier.  The
+   traditional behavior to show the full path relative to the top of
+   the work tree can be had by setting status.relativepaths
+   configuration variable to false.
+
+ * "git blame" kept text for each annotated revision in core needlessly;
+   this has been corrected.
+
+ * "git shortlog" learned to default to HEAD when the standard input is
+   a terminal and the user did not give any revision parameter.
+
+ * "git shortlog" learned "-e" option to show e-mail addresses as well as
+   authors' names.
+
+ * "git help" learned "-w" option to show documentation in browsers.
+
+ * In addition there are quite a few internal clean-ups. Notably:
+
+   - many fork/exec have been replaced with run-command API,
+     brought from the msysgit effort.
+
+   - introduction and more use of the option parser API.
+
+   - enhancement and more use of the strbuf API.
+
+ * Makefile tweaks to support HP-UX is in.
+
+Fixes since v1.5.3
+------------------
+
+All of the fixes in v1.5.3 maintenance series are included in
+this release, unless otherwise noted.
+
+These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
+series.
+
+ * The way "git diff --check" behaves is much more consistent with the way
+   "git apply --whitespace=warn" works.
+
+ * "git svn" talking with the SVN over HTTP will correctly quote branch
+   and project names.
+
+ * "git config" did not work correctly on platforms that define
+   REG_NOMATCH to an even number.
+
+ * Recent versions of AsciiDoc 8 has a change to break our
+   documentation; a workaround has been implemented.
+
+ * "git diff --color-words" colored context lines in a wrong color.

+GIT v1.5.5.5 Release Notes
+==========================
+
+I personally do not think there is any reason anybody should want to
+run v1.5.5.X series these days, because 'master' version is always
+more stable than any tagged released version of git.
+
+This is primarily to futureproof "git-shell" to accept requests
+without a dash between "git" and subcommand name (e.g. "git
+upload-pack") which the newer client will start to make sometime in
+the future.

+GIT v1.5.5 Release Notes
+========================
+
+Updates since v1.5.4
+--------------------
+
+(subsystems)
+
+ * Comes with git-gui 0.10.1
+
+(portability)
+
+ * We shouldn't ask for BSD group ownership semantics by setting g+s bit
+   on directories on older BSD systems that refuses chmod() by non root
+   users.  BSD semantics is the default there anyway.
+
+ * Bunch of portability improvement patches coming from an effort to port
+   to Solaris has been applied.
+
+(performance)
+
+ * On platforms with suboptimal qsort(3) implementation, there
+   is an option to use more reasonable substitute we ship with
+   our software.
+
+ * New configuration variable "pack.packsizelimit" can be used
+   in place of command line option --max-pack-size.
+
+ * "git fetch" over the native git protocol used to make a
+   connection to find out the set of current remote refs and
+   another to actually download the pack data.  We now use only
+   one connection for these tasks.
+
+ * "git commit" does not run lstat(2) more than necessary
+   anymore.
+
+(usability, bells and whistles)
+
+ * Bash completion script (in contrib) are aware of more commands and
+   options.
+
+ * You can be warned when core.autocrlf conversion is applied in
+   such a way that results in an irreversible conversion.
+
+ * A catch-all "color.ui" configuration variable can be used to
+   enable coloring of all color-capable commands, instead of
+   individual ones such as "color.status" and "color.branch".
+
+ * The commands refused to take absolute pathnames where they
+   require pathnames relative to the work tree or the current
+   subdirectory.  They now can take absolute pathnames in such a
+   case as long as the pathnames do not refer outside of the
+   work tree.  E.g. "git add $(pwd)/foo" now works.
+
+ * Error messages used to be sent to stderr, only to get hidden,
+   when $PAGER was in use.  They now are sent to stdout along
+   with the command output to be shown in the $PAGER.
+
+ * A pattern "foo/" in .gitignore file now matches a directory
+   "foo".  Pattern "foo" also matches as before.
+
+ * bash completion's prompt helper function can talk about
+   operation in-progress (e.g. merge, rebase, etc.).
+
+ * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
+   used to tell "git-fetch" and "git-push" to use different URL than what
+   is given from the command line.
+
+ * "git add -i" behaves better even before you make an initial commit.
+
+ * "git am" refused to run from a subdirectory without a good reason.
+
+ * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
+   a line before the fix can appear as a context or preimage line in a
+   later patch, causing the patch not to apply.  The command now knows to
+   see through whitespace fixes done to context lines to successfully
+   apply such a patch series.
+
+ * "git branch" (and "git checkout -b") to branch from a local branch can
+   optionally set "branch.<name>.merge" to mark the new branch to build on
+   the other local branch, when "branch.autosetupmerge" is set to
+   "always", or when passing the command line option "--track" (this option
+   was ignored when branching from local branches).  By default, this does
+   not happen when branching from a local branch.
+
+ * "git checkout" to switch to a branch that has "branch.<name>.merge" set
+   (i.e. marked to build on another branch) reports how much the branch
+   and the other branch diverged.
+
+ * When "git checkout" has to update a lot of paths, it used to be silent
+   for 4 seconds before it showed any progress report.  It is now a bit
+   more impatient and starts showing progress report early.
+
+ * "git commit" learned a new hook "prepare-commit-msg" that can
+   inspect what is going to be committed and prepare the commit
+   log message template to be edited.
+
+ * "git cvsimport" can now take more than one -M options.
+
+ * "git describe" learned to limit the tags to be used for
+   naming with --match option.
+
+ * "git describe --contains" now barfs when the named commit
+   cannot be described.
+
+ * "git describe --exact-match" describes only commits that are tagged.
+
+ * "git describe --long" describes a tagged commit as $tag-0-$sha1,
+   instead of just showing the exact tagname.
+
+ * "git describe" warns when using a tag whose name and path contradict
+   with each other.
+
+ * "git diff" learned "--relative" option to limit and output paths
+   relative to the current directory when working in a subdirectory.
+
+ * "git diff" learned "--dirstat" option to show birds-eye-summary of
+   changes more concisely than "--diffstat".
+
+ * "git format-patch" learned --cover-letter option to generate a cover
+   letter template.
+
+ * "git gc" learned --quiet option.
+
+ * "git gc" now automatically prunes unreachable objects that are two
+   weeks old or older.
+
+ * "git gc --auto" can be disabled more easily by just setting gc.auto
+   to zero.  It also tolerates more packfiles by default.
+
+ * "git grep" now knows "--name-only" is a synonym for the "-l" option.
+
+ * "git help <alias>" now reports "'git <alias>' is alias to <what>",
+   instead of saying "No manual entry for git-<alias>".
+
+ * "git help" can use different backends to show manual pages and this can
+   be configured using "man.viewer" configuration.
+
+ * "gitk" does not restore window position from $HOME/.gitk anymore (it
+   still restores the size).
+
+ * "git log --grep=<what>" learned "--fixed-strings" option to look for
+   <what> without treating it as a regular expression.
+
+ * "git gui" learned an auto-spell checking.
+
+ * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
+   expected; they push the current branch (and only the current branch).
+   In addition, HEAD can be written as the value of "remote.<there>.push"
+   configuration variable.
+
+ * When the configuration variable "pack.threads" is set to 0, "git
+   repack" auto detects the number of CPUs and uses that many threads.
+
+ * "git send-email" learned to prompt for passwords
+   interactively.
+
+ * "git send-email" learned an easier way to suppress CC
+   recipients.
+
+ * "git stash" learned "pop" command, that applies the latest stash and
+   removes it from the stash, and "drop" command to discard the named
+   stash entry.
+
+ * "git submodule" learned a new subcommand "summary" to show the
+   symmetric difference between the HEAD version and the work tree version
+   of the submodule commits.
+
+ * Various "git cvsimport", "git cvsexportcommit", "git cvsserver",
+   "git svn" and "git p4" improvements.
+
+(internal)
+
+ * Duplicated code between git-help and git-instaweb that
+   launches user's preferred browser has been refactored.
+
+ * It is now easier to write test scripts that records known
+   breakages.
+
+ * "git checkout" is rewritten in C.
+
+ * "git remote" is rewritten in C.
+
+ * Two conflict hunks that are separated by a very short span of common
+   lines are now coalesced into one larger hunk, to make the result easier
+   to read.
+
+ * Run-command API's use of file descriptors is documented clearer and
+   is more consistent now.
+
+ * diff output can be sent to FILE * that is different from stdout.  This
+   will help reimplementing more things in C.
+
+Fixes since v1.5.4
+------------------
+
+All of the fixes in v1.5.4 maintenance series are included in
+this release, unless otherwise noted.
+
+ * "git-http-push" did not allow deletion of remote ref with the usual
+   "push <remote> :<branch>" syntax.
+
+ * "git-rebase --abort" did not go back to the right location if
+   "git-reset" was run during the "git-rebase" session.
+
+ * "git imap-send" without setting imap.host did not error out but
+   segfaulted.

+GIT v1.5.6.1 Release Notes
+==========================
+
+Fixes since v1.5.6
+------------------
+
+* Last minute change broke loose object creation on AIX.
+
+* (performance fix) We used to make $GIT_DIR absolute path early in the
+  programs but keeping it relative to the current directory internally
+  gives 1-3 per-cent performance boost.
+
+* bash completion knows the new --graph option to git-log family.
+
+
+* git-diff -c/--cc showed unnecessary "deletion" lines at the context
+  boundary.
+
+* git-for-each-ref ignored %(object) and %(type) requests for tag
+  objects.
+
+* git-merge usage had a typo.
+
+* Rebuilding of git-svn metainfo database did not take rewriteRoot
+  option into account.
+
+* Running "git-rebase --continue/--skip/--abort" before starting a
+  rebase gave nonsense error messages.

+GIT v1.5.6.2 Release Notes
+==========================
+
+Futureproof
+-----------
+
+ * "git-shell" accepts requests without a dash between "git" and
+   subcommand name (e.g. "git upload-pack") which the newer client will
+   start to make sometime in the future.
+
+Fixes since v1.5.6.1
+--------------------
+
+* "git clone" from a remote that is named with url.insteadOf setting in
+  $HOME/.gitconfig did not work well.
+
+* "git describe --long --tags" segfaulted when the described revision was
+  tagged with a lightweight tag.
+
+* "git diff --check" did not report the result via its exit status
+  reliably.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+  it has branch 'foo/bar', it refuses to lose the existing remote tracking
+  branch and its reflog.  The error message has been improved to suggest
+  pruning the remote if the user wants to proceed and get the latest set
+  of branches from the remote, including such 'foo/bar'.
+
+* "git reset file" should mean the same thing as "git reset HEAD file",
+  but we required disambiguating -- even when "file" is not ambiguous.
+
+* "git show" segfaulted when an annotated tag that points at another
+  annotated tag was given to it.
+
+* Optimization for a large import via "git-svn" introduced in v1.5.6 had a
+  serious memory and temporary file leak, which made it unusable for
+  moderately large import.
+
+* "git-svn" mangled remote nickname used in the configuration file
+  unnecessarily.

+GIT v1.5.6.3 Release Notes
+==========================
+
+Fixes since v1.5.6.2
+--------------------
+
+* Setting core.sharedrepository to traditional "true" value was supposed to make
+  the repository group writable but should not affect permission for others.
+  However, since 1.5.6, it was broken to drop permission for others when umask is
+  022, making the repository unreadable by others.
+
+* Setting GIT_TRACE will report spawning of external process via run_command().
+
+* Using an object with very deep delta chain pinned memory needed for extracting
+  intermediate base objects unnecessarily long, leading to excess memory usage.
+
+* Bash completion script did not notice '--' marker on the command
+  line and tried the relatively slow "ref completion" even when
+  completing arguments after one.
+
+* Registering a non-empty blob racily and then truncating the working
+  tree file for it confused "racy-git avoidance" logic into thinking
+  that the path is now unchanged.
+
+* The section that describes attributes related to git-archive were placed
+  in a wrong place in the gitattributes(5) manual page.
+
+* "git am" was not helpful to the users when it detected that the committer
+  information is not set up properly yet.
+
+* "git clone" had a leftover debugging fprintf().
+
+* "git clone -q" was not quiet enough as it used to and gave object count
+  and progress reports.
+
+* "git clone" marked downloaded packfile with .keep; this could be a
+  good thing if the remote side is well packed but otherwise not,
+  especially for a project that is not really big.
+
+* "git daemon" used to call syslog() from a signal handler, which
+  could raise signals of its own but generally is not reentrant.  This
+  was fixed by restructuring the code to report syslog() after the handler
+  returns.
+
+* When "git push" tries to remove a remote ref, and corresponding
+  tracking ref is missing, we used to report error (i.e. failure to
+  remove something that does not exist).
+
+* "git mailinfo" (hence "git am") did not handle commit log messages in a
+  MIME multipart mail correctly.
+
+Contains other various documentation fixes.

+GIT v1.5.6.4 Release Notes
+==========================
+
+Fixes since v1.5.6.3
+--------------------
+
+* Various commands could overflow its internal buffer on a platform
+  with small PATH_MAX value in a repository that has contents with
+  long pathnames.
+
+* There wasn't a way to make --pretty=format:%<> specifiers to honor
+  .mailmap name rewriting for authors and committers.  Now you can with
+  %aN and %cN.
+
+* Bash completion wasted too many cycles; this has been optimized to be
+  usable again.
+
+* Bash completion lost ref part when completing something like "git show
+  pu:Makefile".
+
+* "git-cvsserver" did not clean up its temporary working area after annotate
+  request.
+
+* "git-daemon" called syslog() from its signal handler, which was a
+  no-no.
+
+* "git-fetch" into an empty repository used to remind that the fetch will
+   be huge by saying "no common commits", but this was an unnecessary
+   noise; it is already known by the user anyway.
+
+* "git-http-fetch" would have segfaulted when pack idx file retrieved
+  from the other side was corrupt.
+
+* "git-index-pack" used too much memory when dealing with a deep delta chain.
+
+* "git-mailinfo" (hence "git-am") did not correctly handle in-body [PATCH]
+  line to override the commit title taken from the mail Subject header.
+
+* "git-rebase -i -p" lost parents that are not involved in the history
+  being rewritten.
+
+* "git-rm" lost track of where the index file was when GIT_DIR was
+  specified as a relative path.
+
+* "git-rev-list --quiet" was not quiet as advertised.
+
+Contains other various documentation fixes.

+GIT v1.5.6 Release Notes
+========================
+
+Updates since v1.5.5
+--------------------
+
+(subsystems)
+
+* Comes with updated gitk and git-gui.
+
+(portability)
+
+* git will build on AIX better than before now.
+
+* core.ignorecase configuration variable can be used to work better on
+  filesystems that are not case sensitive.
+
+* "git init" now autodetects the case sensitivity of the filesystem and
+  sets core.ignorecase accordingly.
+
+* cpio is no longer used; neither "curl" binary (libcurl is still used).
+
+(documentation)
+
+* Many freestanding documentation pages have been converted and made
+  available to "git help" (aka "man git<something>") as section 7 of
+  the manual pages. This means bookmarks to some HTML documentation
+  files may need to be updated (eg "tutorial.html" became
+  "gittutorial.html").
+
+(performance)
+
+* "git clone" was rewritten in C.  This will hopefully help cloning a
+  repository with insane number of refs.
+
+* "git rebase --onto $there $from $branch" used to switch to the tip of
+  $branch only to immediately reset back to $from, smudging work tree
+  files unnecessarily.  This has been optimized.
+
+* Object creation codepath in "git-svn" has been optimized by enhancing
+  plumbing commands git-cat-file and git-hash-object.
+
+(usability, bells and whistles)
+
+* "git add -p" (and the "patch" subcommand of "git add -i") can choose to
+  apply (or not apply) mode changes independently from contents changes.
+
+* "git bisect help" gives longer and more helpful usage information.
+
+* "git bisect" does not use a special branch "bisect" anymore; instead, it
+  does its work on a detached HEAD.
+
+* "git branch" (and "git checkout -b") can be told to set up
+  branch.<name>.rebase automatically, so that later you can say "git pull"
+  and magically cause "git pull --rebase" to happen.
+
+* "git branch --merged" and "git branch --no-merged" can be used to list
+  branches that have already been merged (or not yet merged) to the
+  current branch.
+
+* "git cherry-pick" and "git revert" can add a sign-off.
+
+* "git commit" mentions the author identity when you are committing
+  somebody else's changes.
+
+* "git diff/log --dirstat" output is consistent between binary and textual
+  changes.
+
+* "git filter-branch" rewrites signed tags by demoting them to annotated.
+
+* "git format-patch --no-binary" can produce a patch that lack binary
+  changes (i.e. cannot be used to propagate the whole changes) meant only
+  for reviewing.
+
+* "git init --bare" is a synonym for "git --bare init" now.
+
+* "git gc --auto" honors a new pre-auto-gc hook to temporarily disable it.
+
+* "git log --pretty=tformat:<custom format>" gives a LF after each entry,
+  instead of giving a LF between each pair of entries which is how
+  "git log --pretty=format:<custom format>" works.
+
+* "git log" and friends learned the "--graph" option to show the ancestry
+  graph at the left margin of the output.
+
+* "git log" and friends can be told to use date format that is different
+  from the default via 'log.date' configuration variable.
+
+* "git send-email" now can send out messages outside a git repository.
+
+* "git send-email --compose" was made aware of rfc2047 quoting.
+
+* "git status" can optionally include output from "git submodule
+  summary".
+
+* "git svn" learned --add-author-from option to propagate the authorship
+  by munging the commit log message.
+
+* new object creation and looking up in "git svn" has been optimized.
+
+* "gitweb" can read from a system-wide configuration file.
+
+(internal)
+
+* "git unpack-objects" and "git receive-pack" is now more strict about
+  detecting breakage in the objects they receive over the wire.
+
+
+Fixes since v1.5.5
+------------------
+
+All of the fixes in v1.5.5 maintenance series are included in
+this release, unless otherwise noted.
+
+And there are too numerous small fixes to otherwise note here ;-)

+GIT v1.6.0.2 Release Notes
+==========================
+
+Fixes since v1.6.0.1
+--------------------
+
+* Installation on platforms that needs .exe suffix to git-* programs were
+  broken in 1.6.0.1.
+
+* Installation on filesystems without symbolic links support did not
+  work well.
+
+* In-tree documentations and test scripts now use "git foo" form to set a
+  better example, instead of the "git-foo" form (which is an acceptable
+  form if you have "PATH=$(git --exec-path):$PATH" in your script)
+
+* Many commands did not use the correct working tree location when used
+  with GIT_WORK_TREE environment settings.
+
+* Some systems need to use compatibility fnmatch and regex libraries
+  independent from each other; the compat/ area has been reorganized to
+  allow this.
+
+
+* "git apply --unidiff-zero" incorrectly applied a -U0 patch that inserts
+  a new line before the second line.
+
+* "git blame -c" did not exactly work like "git annotate" when range
+  boundaries are involved.
+
+* "git checkout file" when file is still unmerged checked out contents from
+  a random high order stage, which was confusing.
+
+* "git clone $there $here/" with extra trailing slashes after explicit
+  local directory name $here did not work as expected.
+
+* "git diff" on tracked contents with CRLF line endings did not drive "less"
+  intelligently when showing added or removed lines.
+
+* "git diff --dirstat -M" did not add changes in subdirectories up
+  correctly for renamed paths.
+
+* "git diff --cumulative" did not imply "--dirstat".
+
+* "git for-each-ref refs/heads/" did not work as expected.
+
+* "git gui" allowed users to feed patch without any context to be applied.
+
+* "git gui" botched parsing "diff" output when a line that begins with two
+  dashes and a space gets removed or a line that begins with two pluses
+  and a space gets added.
+
+* "git gui" translation updates and i18n fixes.
+
+* "git index-pack" is more careful against disk corruption while completing
+  a thin pack.
+
+* "git log -i --grep=pattern" did not ignore case; neither "git log -E
+  --grep=pattern" triggered extended regexp.
+
+* "git log --pretty="%ad" --date=short" did not use short format when
+  showing the timestamp.
+
+* "git log --author=author" match incorrectly matched with the
+  timestamp part of "author " line in commit objects.
+
+* "git log -F --author=author" did not work at all.
+
+* Build procedure for "git shell" that used stub versions of some
+  functions and globals was not understood by linkers on some platforms.
+
+* "git stash" was fooled by a stat-dirty but otherwise unmodified paths
+  and refused to work until the user refreshed the index.
+
+* "git svn" was broken on Perl before 5.8 with recent fixes to reduce
+  use of temporary files.
+
+* "git verify-pack -v" did not work correctly when given more than one
+  packfile.
+
+Also contains many documentation updates.

+GIT v1.6.0.3 Release Notes
+==========================
+
+Fixes since v1.6.0.2
+--------------------
+
+* "git archive --format=zip" did not honor core.autocrlf while
+  --format=tar did.
+
+* Continuing "git rebase -i" was very confused when the user left modified
+  files in the working tree while resolving conflicts.
+
+* Continuing "git rebase -i" was also very confused when the user left
+  some staged changes in the index after "edit".
+
+* "git rebase -i" now honors the pre-rebase hook, just like the
+  other rebase implementations "git rebase" and "git rebase -m".
+
+* "git rebase -i" incorrectly aborted when there is no commit to replay.
+
+* Behaviour of "git diff --quiet" was inconsistent with "diff --exit-code"
+  with the output redirected to /dev/null.
+
+* "git diff --no-index" on binary files no longer outputs a bogus
+  "diff --git" header line.
+
+* "git diff" hunk header patterns with multiple elements separated by LF
+  were not used correctly.
+
+* Hunk headers in "git diff" default to using extended regular
+  expressions, fixing some of the internal patterns on non-GNU
+  platforms.
+
+* New config "diff.*.xfuncname" exposes extended regular expressions
+  for user specified hunk header patterns.
+
+* "git gc" when ejecting otherwise unreachable objects from packfiles into
+  loose form leaked memory.
+
+* "git index-pack" was recently broken and mishandled objects added by
+  thin-pack completion processing under memory pressure.
+
+* "git index-pack" was recently broken and misbehaved when run from inside
+  .git/objects/pack/ directory.
+
+* "git stash apply sash@{1}" was fixed to error out.  Prior versions
+  would have applied stash@{0} incorrectly.
+
+* "git stash apply" now offers a better suggestion on how to continue
+  if the working tree is currently dirty.
+
+* "git for-each-ref --format=%(subject)" fixed for commits with no
+  no newline in the message body.
+
+* "git remote" fixed to protect printf from user input.
+
+* "git remote show -v" now displays all URLs of a remote.
+
+* "git checkout -b branch" was confused when branch already existed.
+
+* "git checkout -q" once again suppresses the locally modified file list.
+
+* "git clone -q", "git fetch -q" asks remote side to not send
+  progress messages, actually making their output quiet.
+
+* Cross-directory renames are no longer used when creating packs.  This
+  allows more graceful behavior on filesystems like sshfs.
+
+* Stale temporary files under $GIT_DIR/objects/pack are now cleaned up
+  automatically by "git prune".
+
+* "git merge" once again removes directories after the last file has
+  been removed from it during the merge.
+
+* "git merge" did not allocate enough memory for the structure itself when
+  enumerating the parents of the resulting commit.
+
+* "git blame -C -C" no longer segfaults while trying to pass blame if
+   it encounters a submodule reference.
+
+* "git rm" incorrectly claimed that you have local modifications when a
+  path was merely stat-dirty.
+
+* "git svn" fixed to display an error message when 'set-tree' failed,
+   instead of a Perl compile error.
+
+* "git submodule" fixed to handle checking out a different commit
+  than HEAD after initializing the submodule.
+
+* The "git commit" error message when there are still unmerged
+  files present was clarified to match "git write-tree".
+
+* "git init" was confused when core.bare or core.sharedRepository are set
+  in system or user global configuration file by mistake.  When --bare or
+  --shared is given from the command line, these now override such
+  settings made outside the repositories.
+
+* Some segfaults due to uncaught NULL pointers were fixed in multiple
+  tools such as apply, reset, update-index.
+
+* Solaris builds now default to OLD_ICONV=1 to avoid compile warnings;
+  Solaris 8 does not define NEEDS_LIBICONV by default.
+
+* "Git.pm" tests relied on unnecessarily more recent version of Perl.
+
+* "gitweb" triggered undef warning on commits without log messages.
+
+* "gitweb" triggered undef warnings on missing trees.
+
+* "gitweb" now removes PATH_INFO from its URLs so users don't have
+  to manually set the URL in the gitweb configuration.
+
+* Bash completion removed support for legacy "git-fetch", "git-push"
+  and "git-pull" as these are no longer installed.  Dashless form
+  ("git fetch") is still however supported.
+
+Many other documentation updates.

+
+* "git diff" always allowed GIT_EXTERNAL_DIFF and --no-ext-diff was no-op for

+* "git push $there" when the remote $there is defined in $GIT_DIR/branches/$there
+  behaves more like what cg-push from Cogito used to work.
+
+* when giving up resolving a conflicted merge, "git reset --hard" failed
+  to remove new paths from the working tree.
+
+* "git tag" did not complain when given mutually incompatible set of options.
+
+* The message constructed in the internal editor was discarded when "git
+  tag -s" failed to sign the message, which was often caused by the user
+  not configuring GPG correctly.
+
+* "make check" cannot be run without sparse; people may have meant to say
+  "make test" instead, so suggest that.
+
+* Internal diff machinery had a corner case performance bug that choked on
+  a large file with many repeated contents.
+
+* "git repack" used to grab objects out of packs marked with .keep
+  into a new pack.
+
+* Many unsafe call to sprintf() style varargs functions are corrected.
+
+* Also contains quite a few documentation updates.

+GIT v1.6.0.6 Release Notes
+==========================
+
+Fixes since 1.6.0.5
+-------------------
+
+ * "git fsck" had a deep recursion that wasted stack space.
+
+ * "git fast-export" and "git fast-import" choked on an old style
+   annotated tag that lack the tagger information.
+
+ * "git mergetool -- file" did not correctly skip "--" marker that
+   signals the end of options list.
+
+ * "git show $tag" segfaulted when an annotated $tag pointed at a
+   nonexistent object.
+
+ * "git show 2>error" when the standard output is automatically redirected
+   to the pager redirected the standard error to the pager as well; there
+   was no need to.
+
+ * "git send-email" did not correctly handle list of addresses when
+   they had quoted comma (e.g. "Lastname, Givenname" <mail@addre.ss>).
+
+ * Logic to discover branch ancestry in "git svn" was unreliable when
+   the process to fetch history was interrupted.
+
+ * Removed support for an obsolete gitweb request URI, whose
+   implementation ran "git diff" Porcelain, instead of using plumbing,
+   which would have run an external diff command specified in the
+   repository configuration as the gitweb user.
+
+Also contains numerous documentation typofixes.

+GIT v1.6.0 Release Notes
+========================
+
+User visible changes
+--------------------
+
+With the default Makefile settings, most of the programs are now
+installed outside your $PATH, except for "git", "gitk" and
+some server side programs that need to be accessible for technical
+reasons.  Invoking a git subcommand as "git-xyzzy" from the command
+line has been deprecated since early 2006 (and officially announced in
+1.5.4 release notes); use of them from your scripts after adding
+output from "git --exec-path" to the $PATH is still supported in this
+release, but users are again strongly encouraged to adjust their
+scripts to use "git xyzzy" form, as we will stop installing
+"git-xyzzy" hardlinks for built-in commands in later releases.
+
+An earlier change to page "git status" output was overwhelmingly unpopular
+and has been reverted.
+
+Source changes needed for porting to MinGW environment are now all in the
+main git.git codebase.
+
+By default, packfiles created with this version uses delta-base-offset
+encoding introduced in v1.4.4.  Pack idx files are using version 2 that
+allows larger packs and added robustness thanks to its CRC checking,
+introduced in v1.5.2 and v1.4.4.5.  If you want to keep your repositories
+backwards compatible past these versions, set repack.useDeltaBaseOffset
+to false or pack.indexVersion to 1, respectively.
+
+We used to prevent sample hook scripts shipped in templates/ from
+triggering by default by relying on the fact that we install them as
+unexecutable, but on some filesystems, this approach does not work.
+They are now shipped with ".sample" suffix.  If you want to activate
+any of these samples as-is, rename them to drop the ".sample" suffix,
+instead of running "chmod +x" on them.  For example, you can rename
+hooks/post-update.sample to hooks/post-update to enable the sample
+hook that runs update-server-info, in order to make repositories
+friendly to dumb protocols (i.e. HTTP).
+
+GIT_CONFIG, which was only documented as affecting "git config", but
+actually affected all git commands, now only affects "git config".
+GIT_LOCAL_CONFIG, also only documented as affecting "git config" and
+not different from GIT_CONFIG in a useful way, is removed.
+
+The ".dotest" temporary area "git am" and "git rebase" use is now moved
+inside the $GIT_DIR, to avoid mistakes of adding it to the project by
+accident.
+
+An ancient merge strategy "stupid" has been removed.
+
+
+Updates since v1.5.6
+--------------------
+
+(subsystems)
+
+* git-p4 in contrib learned "allowSubmit" configuration to control on
+  which branch to allow "submit" subcommand.
+
+* git-gui learned to stage changes per-line.
+
+(portability)
+
+* Changes for MinGW port have been merged, thanks to Johannes Sixt and
+  gangs.
+
+* Sample hook scripts shipped in templates/ are now suffixed with
+  *.sample.
+
+* perl's in-place edit (-i) does not work well without backup files on Windows;
+  some tests are rewritten to cope with this.
+
+(documentation)
+
+* Updated howto/update-hook-example
+
+* Got rid of usage of "git-foo" from the tutorial and made typography
+  more consistent.
+
+* Disambiguating "--" between revs and paths is finally documented.
+
+(performance, robustness, sanity etc.)
+
+* index-pack used too much memory when dealing with a deep delta chain.
+  This has been optimized.
+
+* reduced excessive inlining to shrink size of the "git" binary.
+
+* verify-pack checks the object CRC when using version 2 idx files.
+
+* When an object is corrupt in a pack, the object became unusable even
+  when the same object is available in a loose form,  We now try harder to
+  fall back to these redundant objects when able.  In particular, "git
+  repack -a -f" can be used to fix such a corruption as long as necessary
+  objects are available.
+
+* Performance of "git-blame -C -C" operation is vastly improved.
+
+* git-clone does not create refs in loose form anymore (it behaves as
+  if you immediately ran git-pack-refs after cloning).  This will help
+  repositories with insanely large number of refs.
+
+* core.fsyncobjectfiles configuration can be used to ensure that the loose
+  objects created will be fsync'ed (this is only useful on filesystems
+  that does not order data writes properly).
+
+* "git commit-tree" plumbing can make Octopus with more than 16 parents.
+  "git commit" has been capable of this for quite some time.
+
+(usability, bells and whistles)
+
+* even more documentation pages are now accessible via "man" and "git help".
+
+* A new environment variable GIT_CEILING_DIRECTORIES can be used to stop
+  the discovery process of the toplevel of working tree; this may be useful
+  when you are working in a slow network disk and are outside any working tree,
+  as bash-completion and "git help" may still need to run in these places.
+
+* By default, stash entries never expire.  Set reflogexpire in [gc
+  "refs/stash"] to a reasonable value to get traditional auto-expiration
+  behaviour back
+
+* Longstanding latency issue with bash completion script has been
+  addressed.  This will need to be backmerged to 'maint' later.
+
+* pager.<cmd> configuration variable can be used to enable/disable the
+  default paging behaviour per command.
+
+* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
+  manually.
+
+* git-am records the original tip of the branch in ORIG_HEAD before it
+  starts applying patches.
+
+* git-apply can handle a patch that touches the same path more than once
+  much better than before.
+
+* git-apply can be told not to trust the line counts recorded in the input
+  patch but recount, with the new --recount option.
+
+* git-apply can be told to apply a patch to a path deeper than what the
+  patch records with --directory option.
+
+* git-archive can be told to omit certain paths from its output using
+  export-ignore attributes.
+
+* git-archive uses the zlib default compression level when creating
+  zip archive.
+
+* git-archive's command line options --exec and --remote can take their
+  parameters as separate command line arguments, similar to other commands.
+  IOW, both "--exec=path" and "--exec path" are now supported.
+
+* With -v option, git-branch describes the remote tracking statistics
+  similar to the way git-checkout reports by how many commits your branch
+  is ahead/behind.
+
+* git-branch's --contains option used to always require a commit parameter
+  to limit the branches with; it now defaults to list branches that
+  contains HEAD if this parameter is omitted.
+
+* git-branch's --merged and --no-merged option used to always limit the
+  branches relative to the HEAD, but they can now take an optional commit
+  argument that is used in place of HEAD.
+
+* git-bundle can read the revision arguments from the standard input.
+
+* git-cherry-pick can replay a root commit now.
+
+* git-clone can clone from a remote whose URL would be rewritten by
+  configuration stored in $HOME/.gitconfig now.
+
+* "git-clone --mirror" is a handy way to set up a bare mirror repository.
+
+* git-cvsserver learned to respond to "cvs co -c".
+
+* git-diff --check now checks leftover merge conflict markers.
+
+* "git-diff -p" learned to grab a better hunk header lines in
+  BibTex, Pascal/Delphi, and Ruby files and also pays attention to
+  chapter and part boundary in TeX documents.
+
+* When remote side used to have branch 'foo' and git-fetch finds that now
+  it has branch 'foo/bar', it refuses to lose the existing remote tracking
+  branch and its reflog.  The error message has been improved to suggest
+  pruning the remote if the user wants to proceed and get the latest set
+  of branches from the remote, including such 'foo/bar'.
+
+* fast-export learned to export and import marks file; this can be used to
+  interface with fast-import incrementally.
+
+* fast-import and fast-export learned to export and import gitlinks.
+
+* "gitk" left background process behind after being asked to dig very deep
+  history and the user killed the UI; the process is killed when the UI goes
+  away now.
+
+* git-rebase records the original tip of branch in ORIG_HEAD before it is
+  rewound.
+
+* "git rerere" can be told to update the index with auto-reused resolution
+  with rerere.autoupdate configuration variable.
+
+* git-rev-parse learned $commit^! and $commit^@ notations used in "log"
+  family.  These notations are available in gitk as well, because the gitk
+  command internally uses rev-parse to interpret its arguments.
+
+* git-rev-list learned --children option to show child commits it
+  encountered during the traversal, instead of showing parent commits.
+
+* git-send-mail can talk not just over SSL but over TLS now.
+
+* git-shortlog honors custom output format specified with "--pretty=format:".
+
+* "git-stash save" learned --keep-index option.  This lets you stash away the
+  local changes and bring the changes staged in the index to your working
+  tree for examination and testing.
+
+* git-stash also learned branch subcommand to create a new branch out of
+  stashed changes.
+
+* git-status gives the remote tracking statistics similar to the way
+  git-checkout reports by how many commits your branch is ahead/behind.
+
+* "git-svn dcommit" is now aware of auto-props setting the subversion user
+  has.
+
+* You can tell "git status -u" to even more aggressively omit checking
+  untracked files with --untracked-files=no.
+
+* Original SHA-1 value for "update-ref -d" is optional now.
+
+* Error codes from gitweb are made more descriptive where possible, rather
+  than "403 forbidden" as we used to issue everywhere.
+
+(internal)
+
+* git-merge has been reimplemented in C.
+
+
+Fixes since v1.5.6
+------------------
+
+All of the fixes in v1.5.6 maintenance series are included in
+this release, unless otherwise noted.
+
+ * git-clone ignored its -u option; the fix needs to be backported to
+   'maint';
+
+ * git-mv used to lose the distinction between changes that are staged
+   and that are only in the working tree, by staging both in the index
+   after moving such a path.
+
+ * "git-rebase -i -p" rewrote the parents to wrong ones when amending
+   (either edit or squash) was involved, and did not work correctly
+   when fast forwarding.

+GIT v1.6.1.1 Release Notes
+==========================
+
+Fixes since v1.6.1
+------------------
+
+* "git add frotz/nitfol" when "frotz" is a submodule should have errored
+  out, but it didn't.
+
+* "git apply" took file modes from the patch text and updated the mode
+  bits of the target tree even when the patch was not about mode changes.
+
+* "git bisect view" on Cygwin did not launch gitk
+
+* "git checkout $tree" did not trigger an error.
+
+* "git commit" tried to remove COMMIT_EDITMSG from the work tree by mistake.
+
+* "git describe --all" complained when a commit is described with a tag,
+  which was nonsense.
+
+* "git diff --no-index --" did not trigger no-index (aka "use git-diff as
+  a replacement of diff on untracked files") behaviour.
+
+* "git format-patch -1 HEAD" on a root commit failed to produce patch
+  text.
+
+* "git fsck branch" did not work as advertised; instead it behaved the same
+  way as "git fsck".
+
+* "git log --pretty=format:%s" did not handle a multi-line subject the
+  same way as built-in log listers (i.e. shortlog, --pretty=oneline, etc.)
+
+* "git daemon", and "git merge-file" are more careful when freopen fails
+  and barf, instead of going on and writing to unopened filehandle.
+
+* "git http-push" did not like some RFC 4918 compliant DAV server
+  responses.
+
+* "git merge -s recursive" mistakenly overwritten an untracked file in the
+  work tree upon delete/modify conflict.
+
+* "git merge -s recursive" didn't leave the index unmerged for entries with
+  rename/delete conflicts.
+
+* "git merge -s recursive" clobbered untracked files in the work tree.
+
+* "git mv -k" with more than one erroneous paths misbehaved.
+
+* "git read-tree -m -u" hence branch switching incorrectly lost a
+  subdirectory in rare cases.
+
+* "git rebase -i" issued an unnecessary error message upon a user error of
+  marking the first commit to be "squash"ed.
+
+* "git shortlog" did not format a commit message with multi-line
+  subject correctly.
+
+Many documentation updates.

+GIT v1.6.1.2 Release Notes
+==========================
+
+Fixes since v1.6.1.1
+--------------------
+
+* The logic for rename detection in internal diff used by commands like
+  "git diff" and "git blame" has been optimized to avoid loading the same
+  blob repeatedly.
+
+* We did not allow writing out a blob that is larger than 2GB for no good
+  reason.
+
+* "git format-patch -o $dir", when $dir is a relative directory, used it
+  as relative to the root of the work tree, not relative to the current
+  directory.
+
+* v1.6.1 introduced an optimization for "git push" into a repository (A)
+  that borrows its objects from another repository (B) to avoid sending
+  objects that are available in repository B, when they are not yet used
+  by repository A.  However the code on the "git push" sender side was
+  buggy and did not work when repository B had new objects that are not
+  known by the sender.  This caused pushing into a "forked" repository
+  served by v1.6.1 software using "git push" from v1.6.1 sometimes did not
+  work.  The bug was purely on the "git push" sender side, and has been
+  corrected.
+
+* "git status -v" did not paint its diff output in colour even when
+  color.ui configuration was set.
+
+* "git ls-tree" learned --full-tree option to help Porcelain scripts that
+  want to always see the full path regardless of the current working
+  directory.
+
+* "git grep" incorrectly searched in work tree paths even when they are
+  marked as assume-unchanged.  It now searches in the index entries.
+
+* "git gc" with no grace period needlessly ejected packed but unreachable
+  objects in their loose form, only to delete them right away.

+GIT v1.6.1.3 Release Notes
+==========================
+

+
+* "git diff --binary | git apply" pipeline did not work well when

+
+* Some combinations of -b/-w/--ignore-space-at-eol to "git diff" did
+  not work as expected.
+
+* "git grep" did not pass the -I (ignore binary) option when

+--------------------
+
+* .gitignore learned to handle backslash as a quoting mechanism for
+  comment introduction character "#".
+  This fix was first merged to 1.6.2.1.
+
+* "git fast-export" produced wrong output with some parents missing from
+  commits, when the history is clock-skewed.
+
+* "git fast-import" sometimes failed to read back objects it just wrote

+
+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+  deciding to descend into a subdirectory but they did not match the
+  individual paths correctly.  This caused pathspecs "abc/d ab" to match
+  "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+  and then "ab" incorrectly matched "abc/0" when it shouldn't).
+  This fix was first merged to 1.6.2.3.

+  This fix was first merged to 1.6.2.2.

+  to prevent them from being repacked.
+  This fix was first merged to 1.6.2.3.

+GIT v1.6.1 Release Notes
+========================
+
+Updates since v1.6.0
+--------------------
+
+When some commands (e.g. "git log", "git diff") spawn pager internally, we
+used to make the pager the parent process of the git command that produces
+output.  This meant that the exit status of the whole thing comes from the
+pager, not the underlying git command.  We swapped the order of the
+processes around and you will see the exit code from the command from now
+on.
+
+(subsystems)
+
+* gitk can call out to git-gui to view "git blame" output; git-gui in turn
+  can run gitk from its blame view.
+
+* Various git-gui updates including updated translations.
+
+* Various gitweb updates from repo.or.cz installation.
+
+* Updates to emacs bindings.
+
+(portability)
+
+* A few test scripts used nonportable "grep" that did not work well on
+  some platforms, e.g. Solaris.
+
+* Sample pre-auto-gc script has OS X support.
+
+* Makefile has support for (ancient) FreeBSD 4.9.
+
+(performance)
+
+* Many operations that are lstat(3) heavy can be told to pre-execute
+  necessary lstat(3) in parallel before their main operations, which
+  potentially gives much improved performance for cold-cache cases or in
+  environments with weak metadata caching (e.g. NFS).
+
+* The underlying diff machinery to produce textual output has been
+  optimized, which would result in faster "git blame" processing.
+
+* Most of the test scripts (but not the ones that try to run servers)
+  can be run in parallel.
+
+* Bash completion of refnames in a repository with massive number of
+  refs has been optimized.
+
+* Cygwin port uses native stat/lstat implementations when applicable,
+  which leads to improved performance.
+
+* "git push" pays attention to alternate repositories to avoid sending
+  unnecessary objects.
+
+* "git svn" can rebuild an out-of-date rev_map file.
+
+(usability, bells and whistles)
+
+* When you mistype a command name, git helpfully suggests what it guesses
+  you might have meant to say.  help.autocorrect configuration can be set
+  to a non-zero value to accept the suggestion when git can uniquely
+  guess.
+
+* The packfile machinery hopefully is more robust when dealing with
+  corrupt packs if redundant objects involved in the corruption are
+  available elsewhere.
+
+* "git add -N path..." adds the named paths as an empty blob, so that
+  subsequent "git diff" will show a diff as if they are creation events.
+
+* "git add" gained a built-in synonym for people who want to say "stage
+  changes" instead of "add contents to the staging area" which amounts
+  to the same thing.
+
+* "git apply" learned --include=paths option, similar to the existing
+  --exclude=paths option.
+
+* "git bisect" is careful about a user mistake and suggests testing of
+  merge base first when good is not a strict ancestor of bad.
+
+* "git bisect skip" can take a range of commits.
+
+* "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
+  by default.
+
+* "git check-attr --stdin" can check attributes for multiple paths.
+
+* "git checkout --track origin/hack" used to be a syntax error.  It now
+  DWIMs to create a corresponding local branch "hack", i.e. acts as if you
+  said "git checkout --track -b hack origin/hack".
+
+* "git checkout --ours/--theirs" can be used to check out one side of a
+  conflicting merge during conflict resolution.
+
+* "git checkout -m" can be used to recreate the initial conflicted state
+  during conflict resolution.
+
+* "git cherry-pick" can also utilize rerere for conflict resolution.
+
+* "git clone" learned to be verbose with -v
+
+* "git commit --author=$name" can look up author name from existing
+  commits.
+
+* output from "git commit" has been reworded in a more concise and yet
+  more informative way.
+
+* "git count-objects" reports the on-disk footprint for packfiles and
+  their corresponding idx files.
+
+* "git daemon" learned --max-connections=<count> option.
+
+* "git daemon" exports REMOTE_ADDR to record client address, so that
+  spawned programs can act differently on it.
+
+* "git describe --tags" favours closer lightweight tags than farther
+  annotated tags now.
+
+* "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
+  configuration option.
+
+* "git diff" learned to put more sensible hunk headers for Python,
+  HTML and ObjC contents.
+
+* "git diff" learned to vary the a/ vs b/ prefix depending on what are
+  being compared, controlled by diff.mnemonicprefix configuration.
+
+* "git diff" learned --dirstat-by-file to count changed files, not number
+  of lines, when summarizing the global picture.
+
+* "git diff" learned "textconv" filters --- a binary or hard-to-read
+  contents can be munged into human readable form and the difference
+  between the results of the conversion can be viewed (obviously this
+  cannot produce a patch that can be applied, so this is disabled in
+  format-patch among other things).
+
+* "--cached" option to "git diff has an easier to remember synonym "--staged",
+  to ask "what is the difference between the given commit and the
+  contents staged in the index?"
+
+* "git for-each-ref" learned "refname:short" token that gives an
+  unambiguously abbreviated refname.
+
+* Auto-numbering of the subject lines is the default for "git
+  format-patch" now.
+
+* "git grep" learned to accept -z similar to GNU grep.
+
+* "git help" learned to use GIT_MAN_VIEWER environment variable before
+  using "man" program.
+
+* "git imap-send" can optionally talk SSL.
+
+* "git index-pack" is more careful against disk corruption while
+  completing a thin pack.
+
+* "git log --check" and "git log --exit-code" passes their underlying diff
+  status with their exit status code.
+
+* "git log" learned --simplify-merges, a milder variant of --full-history;
+  "gitk --simplify-merges" is easier to view than with --full-history.
+
+* "git log" learned "--source" to show what ref each commit was reached
+  from.
+
+* "git log" also learned "--simplify-by-decoration" to show the
+  birds-eye-view of the topology of the history.
+
+* "git log --pretty=format:" learned "%d" format element that inserts
+  names of tags that point at the commit.
+
+* "git merge --squash" and "git merge --no-ff" into an unborn branch are
+  noticed as user errors.
+
+* "git merge -s $strategy" can use a custom built strategy if you have a
+  command "git-merge-$strategy" on your $PATH.
+
+* "git pull" (and "git fetch") can be told to operate "-v"erbosely or
+  "-q"uietly.
+
+* "git push" can be told to reject deletion of refs with receive.denyDeletes
+  configuration.
+
+* "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
+
+* "git rebase -p" uses interactive rebase machinery now to preserve the merges.
+
+* "git reflog expire branch" can be used in place of "git reflog expire
+  refs/heads/branch".
+
+* "git remote show $remote" lists remote branches one-per-line now.
+
+* "git send-email" can be given revision range instead of files and
+  maildirs on the command line, and automatically runs format-patch to
+  generate patches for the given revision range.
+
+* "git submodule foreach" subcommand allows you to iterate over checked
+  out submodules.
+
+* "git submodule sync" subcommands allows you to update the origin URL
+  recorded in submodule directories from the toplevel .gitmodules file.
+
+* "git svn branch" can create new branches on the other end.
+
+* "gitweb" can use more saner PATH_INFO based URL.
+
+(internal)
+
+* "git hash-object" learned to lie about the path being hashed, so that
+  correct gitattributes processing can be done while hashing contents
+  stored in a temporary file.
+
+* various callers of git-merge-recursive avoid forking it as an external
+  process.
+
+* Git class defined in "Git.pm" can be subclasses a bit more easily.
+
+* We used to link GNU regex library as a compatibility layer for some
+  platforms, but it turns out it is not necessary on most of them.
+
+* Some path handling routines used fixed number of buffers used alternately
+  but depending on the call depth, this arrangement led to hard to track
+  bugs.  This issue is being addressed.
+
+
+Fixes since v1.6.0
+------------------
+
+All of the fixes in v1.6.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+* Porcelains implemented as shell scripts were utterly confused when you
+  entered to a subdirectory of a work tree from sideways, following a
+  symbolic link (this may need to be backported to older releases later).
+
+* Tracking symbolic links would work better on filesystems whose lstat()
+  returns incorrect st_size value for them.
+
+* "git add" and "git update-index" incorrectly allowed adding S/F when S
+  is a tracked symlink that points at a directory D that has a path F in
+  it (we still need to fix a similar nonsense when S is a submodule and F
+  is a path in it).
+
+* "git am" after stopping at a broken patch lost --whitespace, -C, -p and
+  --3way options given from the command line initially.
+
+* "git diff --stdin" used to take two trees on a line and compared them,
+  but we dropped support for such a use case long time ago.  This has
+  been resurrected.
+
+* "git filter-branch" failed to rewrite a tag name with slashes in it.
+
+* "git http-push" did not understand URI scheme other than opaquelocktoken
+  when acquiring a lock from the server (this may need to be backported to
+  older releases later).
+
+* After "git rebase -p" stopped with conflicts while replaying a merge,
+ "git rebase --continue" did not work (may need to be backported to older
+  releases).
+
+* "git revert" records relative to which parent a revert was made when
+  reverting a merge.  Together with new documentation that explains issues
+  around reverting a merge and merging from the updated branch later, this
+  hopefully will reduce user confusion (this may need to be backported to
+  older releases later).
+
+* "git rm --cached" used to allow an empty blob that was added earlier to
+  be removed without --force, even when the file in the work tree has
+  since been modified.
+
+* "git push --tags --all $there" failed with generic usage message without
+  telling saying these two options are incompatible.
+
+* "git log --author/--committer" match used to potentially match the
+  timestamp part, exposing internal implementation detail.  Also these did
+  not work with --fixed-strings match at all.
+
+* "gitweb" did not mark non-ASCII characters imported from external HTML fragments
+  correctly.

+GIT v1.6.2.2 Release Notes
+==========================
+
+Fixes since v1.6.2.1
+--------------------
+
+* A longstanding confusing description of what --pickaxe option of
+  git-diff does has been clarified in the documentation.
+
+* "git-blame -S" did not quite work near the commits that were given
+  on the command line correctly.
+
+* "git diff --pickaxe-regexp" did not count overlapping matches
+  correctly.
+
+* "git diff" did not feed files in work-tree representation to external
+  diff and textconv.
+
+* "git-fetch" in a repository that was not cloned from anywhere said
+  it cannot find 'origin', which was hard to understand for new people.
+
+* "git-format-patch --numbered-files --stdout" did not have to die of
+  incompatible options; it now simply ignores --numbered-files as no files
+  are produced anyway.
+
+* "git-ls-files --deleted" did not work well with GIT_DIR&GIT_WORK_TREE.
+
+* "git-read-tree A B C..." without -m option has been broken for a long
+  time.
+
+* git-send-email ignored --in-reply-to when --no-thread was given.
+
+* 'git-submodule add' did not tolerate extra slashes and ./ in the path it
+  accepted from the command line; it now is more lenient.
+
+* git-svn misbehaved when the project contained a path that began with
+  two dashes.
+
+* import-zips script (in contrib) did not compute the common directory
+  prefix correctly.
+
+* miscompilation of negated enum constants by old gcc (2.9) affected the
+  codepaths to spawn subprocesses.
+
+Many small documentation updates are included as well.

+
+* git-repack (invoked from git-gc) did not work as nicely as it should in

+  to prevent them from being repacked.

+GIT v1.6.2.4 Release Notes
+==========================

+
+* The configuration parser had a buffer overflow while parsing an overlong
+  value.
+
+* pruning reflog entries that are unreachable from the tip of the ref
+  during "git reflog prune" (hence "git gc") was very inefficient.
+
+* "git-add -p" lacked a way to say "q"uit to refuse staging any hunks for

+
+* "git-checkout <tree-ish> <submodule>" did not update the index entry at
+  the named path; it now does.
+
+* "git-fast-export" choked when seeing a tag that does not point at commit.
+
+* "git init" segfaulted when given an overlong template location via
+  the --template= option.
+
+* "git-ls-tree" and "git-diff-tree" used a pathspec correctly when
+  deciding to descend into a subdirectory but they did not match the
+  individual paths correctly.  This caused pathspecs "abc/d ab" to match
+  "abc/0" ("abc/d" made them decide to descend into the directory "abc/",
+  and then "ab" incorrectly matched "abc/0" when it shouldn't).
+
+* "git-merge-recursive" was broken when a submodule entry was involved in
+  a criss-cross merge situation.
+
+Many small documentation updates are included as well.

+GIT v1.6.2 Release Notes
+========================
+
+With the next major release, "git push" into a branch that is
+currently checked out will be refused by default.  You can choose
+what should happen upon such a push by setting the configuration
+variable receive.denyCurrentBranch in the receiving repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing.  Please refer to:
+
+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning.  You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+
+Updates since v1.6.1
+--------------------
+
+(subsystems)
+
+* git-svn updates.
+
+* gitweb updates, including a new patch view and RSS/Atom feed
+  improvements.
+
+* (contrib/emacs) git.el now has commands for checking out a branch,
+  creating a branch, cherry-picking and reverting commits; vc-git.el
+  is not shipped with git anymore (it is part of official Emacs).
+
+(performance)
+
+* pack-objects autodetects the number of CPUs available and uses threaded
+  version.
+
+(usability, bells and whistles)
+
+* automatic typo correction works on aliases as well
+
+* @{-1} is a way to refer to the last branch you were on.  This is
+  accepted not only where an object name is expected, but anywhere
+  a branch name is expected and acts as if you typed the branch name.
+  E.g. "git branch --track mybranch @{-1}", "git merge @{-1}", and
+  "git rev-parse --symbolic-full-name @{-1}" would work as expected.
+
+* When refs/remotes/origin/HEAD points at a remote tracking branch that
+  has been pruned away, many git operations issued warning when they
+  internally enumerated the refs.  We now warn only when you say "origin"
+  to refer to that pruned branch.
+
+* The location of .mailmap file can be configured, and its file format was
+  enhanced to allow mapping an incorrect e-mail field as well.
+
+* "git add -p" learned 'g'oto action to jump directly to a hunk.
+
+* "git add -p" learned to find a hunk with given text with '/'.
+
+* "git add -p" optionally can be told to work with just the command letter
+  without Enter.
+
+* when "git am" stops upon a patch that does not apply, it shows the
+  title of the offending patch.
+
+* "git am --directory=<dir>" and "git am --reject" passes these options
+  to underlying "git apply".
+
+* "git am" learned --ignore-date option.
+
+* "git blame" aligns author names better when they are spelled in
+  non US-ASCII encoding.
+
+* "git clone" now makes its best effort when cloning from an empty
+  repository to set up configuration variables to refer to the remote
+  repository.
+
+* "git checkout -" is a shorthand for "git checkout @{-1}".
+
+* "git cherry" defaults to whatever the current branch is tracking (if
+  exists) when the <upstream> argument is not given.
+
+* "git cvsserver" can be told not to add extra "via git-CVS emulator" to
+  the commit log message it serves via gitcvs.commitmsgannotation
+  configuration.
+
+* "git cvsserver" learned to handle 'noop' command some CVS clients seem
+  to expect to work.
+
+* "git diff" learned a new option --inter-hunk-context to coalesce close
+  hunks together and show context between them.
+
+* The definition of what constitutes a word for "git diff --color-words"
+  can be customized via gitattributes, command line or a configuration.
+
+* "git diff" learned --patience to run "patience diff" algorithm.
+
+* "git filter-branch" learned --prune-empty option that discards commits
+  that do not change the contents.
+
+* "git fsck" now checks loose objects in alternate object stores, instead
+  of misreporting them as missing.
+
+* "git gc --prune" was resurrected to allow "git gc --no-prune" and
+  giving non-default expiration period e.g. "git gc --prune=now".
+
+* "git grep -w" and "git grep" for fixed strings have been optimized.
+
+* "git mergetool" learned -y(--no-prompt) option to disable prompting.
+
+* "git rebase -i" can transplant a history down to root to elsewhere
+  with --root option.
+
+* "git reset --merge" is a new mode that works similar to the way
+  "git checkout" switches branches, taking the local changes while
+  switching to another commit.
+
+* "git submodule update" learned --no-fetch option.
+
+* "git tag" learned --contains that works the same way as the same option
+  from "git branch".
+
+
+Fixes since v1.6.1
+------------------
+
+All of the fixes in v1.6.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.1.X series.
+
+* "git-add sub/file" when sub is a submodule incorrectly added the path to
+  the superproject.
+
+* "git bundle" did not exclude annotated tags even when a range given
+  from the command line wanted to.
+
+* "git filter-branch" unnecessarily refused to work when you had
+  checked out a different commit from what is recorded in the superproject
+  index in a submodule.
+
+* "git filter-branch" incorrectly tried to update a nonexistent work tree
+  at the end when it is run in a bare repository.
+
+* "git gc" did not work if your repository was created with an ancient git
+  and never had any pack files in it before.
+
+* "git mergetool" used to ignore autocrlf and other attributes
+  based content rewriting.
+
+* branch switching and merges had a silly bug that did not validate
+  the correct directory when making sure an existing subdirectory is
+  clean.
+
+* "git -p cmd" when cmd is not a built-in one left the display in funny state
+  when killed in the middle.

+GIT v1.6.3.2 Release Notes
+==========================
+
+Fixes since v1.6.3.1
+--------------------
+
+ * A few codepaths picked up the first few bytes from an sha1[] by
+   casting the (char *) pointer to (int *); GCC 4.4 did not like this,
+   and aborted compilation.
+
+ * Some unlink(2) failures went undiagnosed.
+
+ * The "recursive" merge strategy misbehaved when faced rename/delete
+   conflicts while coming up with an intermediate merge base.
+
+ * The low-level merge algorithm did not handle a degenerate case of
+   merging a file with itself using itself as the common ancestor
+   gracefully.  It should produce the file itself, but instead
+   produced an empty result.
+
+ * GIT_TRACE mechanism segfaulted when tracing a shell-quoted aliases.
+
+ * OpenBSD also uses st_ctimspec in "struct stat", instead of "st_ctim".
+
+ * With NO_CROSS_DIRECTORY_HARDLINKS, "make install" can be told not to
+   create hardlinks between $(gitexecdir)/git-$builtin_commands and
+   $(bindir)/git.
+
+ * command completion code in bash did not reliably detect that we are
+   in a bare repository.
+
+ * "git add ." in an empty directory complained that pathspec "." did not
+   match anything, which may be technically correct, but not useful.  We
+   silently make it a no-op now.
+
+ * "git add -p" (and "patch" action in "git add -i") was broken when
+   the first hunk that adds a line at the top was split into two and
+   both halves are marked to be used.
+
+ * "git blame path" misbehaved at the commit where path became file
+   from a directory with some files in it.
+
+ * "git for-each-ref" had a segfaulting bug when dealing with a tag object
+   created by an ancient git.
+
+ * "git format-patch -k" still added patch numbers if format.numbered
+   configuration was set.
+
+ * "git grep --color ''" did not terminate.  The command also had
+   subtle bugs with its -w option.
+
+ * http-push had a small use-after-free bug.
+
+ * "git push" was converting OFS_DELTA pack representation into less
+   efficient REF_DELTA representation unconditionally upon transfer,
+   making the transferred data unnecessarily larger.
+
+ * "git remote show origin" segfaulted when origin was still empty.
+
+Many other general usability updates around help text, diagnostic messages
+and documentation are included as well.

+
+ * "git remote show" did not show all the URLs associated with the named
+   remote, even though "git remote -v" did.  Made them consistent by
+   making the former show all URLs.
+
+ * "whitespace" attribute that is set was meant to detect all errors known

+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning.  You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+When the user does not tell "git push" what to push, it has always
+pushed matching refs.  For some people it is unexpected, and a new
+configuration variable push.default has been introduced to allow
+changing a different default behaviour.  To advertise the new feature,
+a big warning is issued if this is not configured and a git push without
+arguments is attempted.
+
+
+Updates since v1.6.2
+--------------------
+
+(subsystems)
+
+* various git-svn updates.
+
+* git-gui updates, including an update to Russian translation, and a
+  fix to an infinite loop when showing an empty diff.
+
+* gitk updates, including an update to Russian translation and improved Windows
+  support.
+
+(performance)
+
+* many uses of lstat(2) in the codepath for "git checkout" have been
+  optimized out.
+
+(usability, bells and whistles)
+
+* Boolean configuration variable yes/no can be written as on/off.
+
+* rsync:/path/to/repo can be used to run git over rsync for local
+  repositories.  It may not be useful in practice; meant primarily for
+  testing.
+
+* http transport learned to prompt and use password when fetching from or
+  pushing to http://user@host.xz/ URL.
+
+* (msysgit) progress output that is sent over the sideband protocol can
+  be handled appropriately in Windows console.
+
+* "--pretty=<style>" option to the log family of commands can now be
+  spelled as "--format=<style>".  In addition, --format=%formatstring
+  is a short-hand for --pretty=tformat:%formatstring.
+
+* "--oneline" is a synonym for "--pretty=oneline --abbrev-commit".
+
+* "--graph" to the "git log" family can draw the commit ancestry graph
+  in colors.
+
+* If you realize that you botched the patch when you are editing hunks
+  with the 'edit' action in git-add -i/-p, you can abort the editor to
+  tell git not to apply it.
+
+* @{-1} is a new way to refer to the last branch you were on introduced in
+  1.6.2, but the initial implementation did not teach this to a few
+  commands.  Now the syntax works with "branch -m @{-1} newname".
+
+* git-archive learned --output=<file> option.
+
+* git-archive takes attributes from the tree being archived; strictly
+  speaking, this is an incompatible behaviour change, but is a good one.
+  Use --worktree-attributes option to allow it to read attributes from
+  the work tree as before (deprecated git-tar tree command always reads
+  attributes from the work tree).
+
+* git-bisect shows not just the number of remaining commits whose goodness
+  is unknown, but also shows the estimated number of remaining rounds.
+
+* You can give --date=<format> option to git-blame.
+
+* "git-branch -r" shows HEAD symref that points at a remote branch in
+  interest of each tracked remote repository.
+
+* "git-branch -v -v" is a new way to get list of names for branches and the
+  "upstream" branch for them.
+
+* git-config learned -e option to open an editor to edit the config file
+  directly.
+
+* git-clone runs post-checkout hook when run without --no-checkout.
+
+* git-difftool is now part of the officially supported command, primarily
+  maintained by David Aguilar.
+
+* git-for-each-ref learned a new "upstream" token.
+
+* git-format-patch can be told to use attachment with a new configuration,
+  format.attach.
+
+* git-format-patch can be told to produce deep or shallow message threads.
+
+* git-format-patch can be told to always add sign-off with a configuration
+  variable.
+
+* git-format-patch learned format.headers configuration to add extra
+  header fields to the output.  This behaviour is similar to the existing
+  --add-header=<header> option of the command.
+
+* git-format-patch gives human readable names to the attached files, when
+  told to send patches as attachments.
+
+* git-grep learned to highlight the found substrings in color.
+
+* git-imap-send learned to work around Thunderbird's inability to easily
+  disable format=flowed with a new configuration, imap.preformattedHTML.
+
+* git-rebase can be told to rebase the series even if your branch is a
+  descendant of the commit you are rebasing onto with --force-rebase
+  option.
+
+* git-rebase can be told to report diffstat with the --stat option.
+
+* Output from git-remote command has been vastly improved.
+
+* "git remote update --prune $remote" updates from the named remote and
+  then prunes stale tracking branches.
+
+* git-send-email learned --confirm option to review the Cc: list before
+  sending the messages out.
+
+(developers)
+
+* Test scripts can be run under valgrind.
+
+* Test scripts can be run with installed git.
+
+* Makefile learned 'coverage' option to run the test suites with
+  coverage tracking enabled.
+
+* Building the manpages with docbook-xsl between 1.69.1 and 1.71.1 now
+  requires setting DOCBOOK_SUPPRESS_SP to work around a docbook-xsl bug.
+  This workaround used to be enabled by default, but causes problems
+  with newer versions of docbook-xsl.  In addition, there are a few more
+  knobs you can tweak to work around issues with various versions of the
+  docbook-xsl package.  See comments in Documentation/Makefile for details.
+
+* Support for building and testing a subset of git on a system without a
+  working perl has been improved.
+
+
+Fixes since v1.6.2
+------------------
+
+All of the fixes in v1.6.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.2.X series.
+
+* "git-apply" rejected a patch that swaps two files (i.e. renames A to B
+  and B to A at the same time).  May need to be backported by cherry
+  picking d8c81df and then 7fac0ee).
+
+* The initial checkout did not read the attributes from the .gitattribute
+  file that is being checked out.
+
+* git-gc spent excessive amount of time to decide if an object appears
+  in a locally existing pack (if needed, backport by merging 69e020a).

+GIT v1.6.4.1 Release Notes
+==========================
+
+Fixes since v1.6.4
+------------------
+
+ * An unquoted value in the configuration file, when it contains more than
+   one whitespaces in a row, got them replaced with a single space.
+
+ * "git am" used to accept a single piece of e-mail per file (not a mbox)
+   as its input, but multiple input format support in v1.6.4 broke it.
+   Apparently many people have been depending on this feature.
+
+ * The short help text for "git filter-branch" command was a single long
+   line, wrapped by terminals, and was hard to read.
+
+ * The "recursive" strategy of "git merge" segfaulted when a merge has
+   more than one merge-bases, and merging of these merge-bases involves
+   a rename/rename or a rename/add conflict.
+
+ * "git pull --rebase" did not use the right fork point when the
+   repository has already fetched from the upstream that rewinds the
+   branch it is based on in an earlier fetch.
+
+ * Explain the concept of fast-forward more fully in "git push"
+   documentation, and hint to refer to it from an error message when the
+   command refuses an update to protect the user.
+
+ * The default value for pack.deltacachesize, used by "git repack", is now
+   256M, instead of unbounded.  Otherwise a repack of a moderately sized
+   repository would needlessly eat into swap.
+
+ * Document how "git repack" (hence "git gc") interacts with a repository
+   that borrows its objects from other repositories (e.g. ones created by
+   "git clone -s").
+
+ * "git show" on an annotated tag lacked a delimiting blank line between
+   the tag itself and the contents of the object it tags.
+
+ * "git verify-pack -v" erroneously reported number of objects with too
+   deep delta depths as "chain length 0" objects.
+
+ * Long names of authors and committers outside US-ASCII were sometimes
+   incorrectly shown in "gitweb".
+
+Other minor documentation updates are included.

+GIT v1.6.4.2 Release Notes
+==========================
+
+Fixes since v1.6.4.1
+--------------------
+
+* --date=relative output between 1 and 5 years ago rounded the number of
+    years when saying X years Y months ago, instead of rounding it down.
+
+* "git add -p" did not handle changes in executable bits correctly
+  (a regression around 1.6.3).
+
+* "git apply" did not honor GNU diff's convention to mark the creation/deletion
+  event with UNIX epoch timestamp on missing side.
+
+* "git checkout" incorrectly removed files in a directory pointed by a
+  symbolic link during a branch switch that replaces a directory with
+  a symbolic link.
+
+* "git clean -d -f" happily descended into a subdirectory that is managed by a
+  separate git repository.  It now requires two -f options for safety.
+
+* "git fetch/push" over http transports had two rather grave bugs.
+
+* "git format-patch --cover-letter" did not prepare the cover letter file
+  for use with non-ASCII strings when there are the series contributors with
+  non-ASCII names.
+
+* "git pull origin branch" and "git fetch origin && git merge origin/branch"
+  left different merge messages in the resulting commit.
+
+Other minor documentation updates are included.

+GIT v1.6.4.3 Release Notes
+==========================
+
+Fixes since v1.6.4.2
+--------------------
+
+* "git clone" from an empty repository gave unnecessary error message,
+  even though it did everything else correctly.
+
+* "git cvsserver" invoked git commands via "git-foo" style, which has long
+  been deprecated.
+
+* "git fetch" and "git clone" had an extra sanity check to verify the
+  presence of the corresponding *.pack file before downloading *.idx
+  file by issuing a HEAD request.  Github server however sometimes
+  gave 500 (Internal server error) response to HEAD even if a GET
+  request for *.pack file to the same URL would have succeeded, and broke
+  clone over HTTP from some of their repositories.  As a workaround, this
+  verification has been removed (as it is not absolutely necessary).
+
+* "git grep" did not like relative pathname to refer outside the current
+  directory when run from a subdirectory.
+
+* an error message from "git push" was formatted in a very ugly way.
+
+* "git svn" did not quote the subversion user name correctly when

+
+Other minor documentation updates are included.

+--------------------
+
+* The workaround for Github server that sometimes gave 500 (Internal server
+  error) response to HEAD requests in 1.6.4.3 introduced a regression that

+* "git pull" on an unborn branch used to consider anything in the work
+  tree and the index discardable.
+
+* "git diff -b/w" did not work well on the incomplete line at the end of
+  the file, due to an incorrect hashing of lines in the low-level xdiff
+  routines.
+
+* "git checkout-index --prefix=$somewhere" used to work when $somewhere is
+  a symbolic link to a directory elsewhere, but v1.6.4.2 broke it.
+
+* "git unpack-objects --strict", invoked when receive.fsckobjects

+GIT v1.6.4 Release Notes
+========================
+
+With the next major release, "git push" into a branch that is
+currently checked out will be refused by default.  You can choose
+what should happen upon such a push by setting the configuration
+variable receive.denyCurrentBranch in the receiving repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing.  Please refer to:
+
+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning.  You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+
+Updates since v1.6.3
+--------------------
+
+(subsystems)
+
+ * gitweb Perl style clean-up.
+
+ * git-svn updates, including a new --authors-prog option to map author
+   names by invoking an external program, 'git svn reset' to unwind
+   'git svn fetch', support for more than one branches, documenting
+   of the useful --minimize-url feature, new "git svn gc" command, etc.
+
+(portability)
+
+ * We feed iconv with "UTF-8" instead of "utf8"; the former is
+   understood more widely.  Similarly updated test scripts to use
+   encoding names more widely understood (e.g. use "ISO8859-1" instead
+   of "ISO-8859-1").
+
+ * Various portability fixes/workarounds for different vintages of
+   SunOS, IRIX, and Windows.
+
+ * Git-over-ssh transport on Windows supports PuTTY plink and TortoisePlink.
+
+(performance)
+
+ * Many repeated use of lstat() are optimized out in "checkout" codepath.
+
+ * git-status (and underlying git-diff-index --cached) are optimized
+   to take advantage of cache-tree information in the index.
+
+(usability, bells and whistles)
+
+ * "git add --edit" lets users edit the whole patch text to fine-tune what
+   is added to the index.
+
+ * "git am" accepts StGIT series file as its input.
+
+ * "git bisect skip" skips to a more randomly chosen place in the hope
+   to avoid testing a commit that is too close to a commit that is
+   already known to be untestable.
+
+ * "git cvsexportcommit" learned -k option to stop CVS keywords expansion
+
+ * "git fast-export" learned to handle history simplification more
+   gracefully.
+
+ * "git fast-export" learned an option --tag-of-filtered-object to handle
+   dangling tags resulting from history simplification more usefully.
+
+ * "git grep" learned -p option to show the location of the match using the
+   same context hunk marker "git diff" uses.
+
+ * https transport can optionally be told that the used client
+   certificate is password protected, in which case it asks the
+   password only once.
+
+ * "git imap-send" is IPv6 aware.
+
+ * "git log --graph" draws graphs more compactly by using horizontal lines
+   when able.
+
+ * "git log --decorate" shows shorter refnames by stripping well-known
+   refs/* prefix.
+
+ * "git push $name" honors remote.$name.pushurl if present before
+   using remote.$name.url.  In other words, the URL used for fetching
+   and pushing can be different.
+
+ * "git send-email" understands quoted aliases in .mailrc files (might
+   have to be backported to 1.6.3.X).
+
+ * "git send-email" can fetch the sender address from the configuration
+   variable "sendmail.from" (and "sendmail.<identity>.from").
+
+ * "git show-branch" can color its output.
+
+ * "add" and "update" subcommands to "git submodule" learned --reference
+   option to use local clone with references.
+
+ * "git submodule update" learned --rebase option to update checked
+   out submodules by rebasing the local changes.
+
+ * "gitweb" can optionally use gravatar to adorn author/committer names.
+
+(developers)
+
+ * A major part of the "git bisect" wrapper has moved to C.
+
+ * Formatting with the new version of AsciiDoc 8.4.1 is now supported.
+
+Fixes since v1.6.3
+------------------
+
+All of the fixes in v1.6.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.3.X series.
+
+ * "git diff-tree -r -t" used to omit new or removed directories from
+   the output.  df533f3 (diff-tree -r -t: include added/removed
+   directories in the output, 2009-06-13) may need to be cherry-picked
+   to backport this fix.
+
+ * The way Git.pm sets up a Repository object was not friendly to callers
+   that chdir around.  It now internally records the repository location
+   as an absolute path when autodetected.
+
+ * Removing a section with "git config --remove-section", when its
+   section header has a variable definition on the same line, lost
+   that variable definition.
+
+ * "git rebase -p --onto" used to always leave side branches of a merge
+   intact, even when both branches are subject to rewriting.
+
+ * "git repack" used to faithfully follow grafts and considered true
+   parents recorded in the commit object unreachable from the commit.
+   After such a repacking, you cannot remove grafts without corrupting
+   the repository.
+
+ * "git send-email" did not detect erroneous loops in alias expansion.

+
+ * "git diff --color-words -U0" didn't work correctly.
+
+ * The handling of blank lines at the end of file by "git diff/apply

+   They are now colored, warned against, and fixed the same way as others.
+
+ * There was no way to allow blank lines at the end of file without
+   allowing extra blanks at the end of lines.  You can use blank-at-eof
+   and blank-at-eol whitespace error class to specify them separately.
+   The old trailing-space error class is now a short-hand to set both.
+

+
+ * "git imap-send" did not compile cleanly with newer OpenSSL.
+
+ * "git help -a" outside of a git repository was broken.

+ * "git ls-files -i" was supposed to be inverse of "git ls-files" without -i
+   with respect to exclude patterns, but it was broken since 1.6.5.2.
+
+ * "git ls-remote" outside of a git repository over http was broken.
+
+ * "git rebase -i" gave bogus error message when the command word was

+   command now runs "gc --auto" and "u-s-i" by setting receive.autogc
+   and receive.updateserverinfo configuration variables, respectively.
+
+ * Release notes spelled the package name with incorrect capitalization.
+
+ * "gitweb" did not escape non-ascii characters correctly in the URL.
+

+   any other branch to merge, it shouldn't be mistaken as such.  We will
+   remove the old style "git merge <message> HEAD <commit>..."  syntax in
+   future versions, but not in this release,
+
+ * "git merge -m <message> <branch>..." added the standard merge message
+   on its own after user-supplied message, which should have overridden the
+   standard one.
+
+Other minor documentation updates are included.

+Git v1.6.5.5 Release Notes
+==========================
+
+Fixes since v1.6.5.4
+--------------------
+
+ * Manual pages can be formatted with older xmlto again.
+
+ * GREP_OPTIONS exported from user's environment could have broken
+   our scripted commands.
+
+ * In configuration files, a few variables that name paths can begin with
+   ~/ and ~username/ and they are expanded as expected.  This is not a
+   bugfix but 1.6.6 will have this and without backporting users cannot
+   easily use the same ~/.gitconfig across versions.
+
+ * "git diff -B -M" did the same computation to hash lines of contents
+   twice, and held onto memory after it has used the data in it
+   unnecessarily before it freed.
+
+ * "git diff -B" and "git diff --dirstat" was not counting newly added
+   contents correctly.
+
+ * "git format-patch revisions... -- path" issued an incorrect error
+   message that suggested to use "--" on the command line when path
+   does not exist in the current work tree (it is a separate matter if
+   it makes sense to limit format-patch with pathspecs like that
+   without using the --full-diff option).
+
+ * "git grep -F -i StRiNg" did not work as expected.
+
+ * Enumeration of available merge strategies iterated over the list of
+   commands in a wrong way, sometimes producing an incorrect result.
+
+ * "git shortlog" did not honor the "encoding" header embedded in the
+   commit object like "git log" did.
+
+ * Reading progress messages that come from the remote side while running
+   "git pull" is given precedence over reading the actual pack data to
+   prevent garbled progress message on the user's terminal.
+
+ * "git rebase" got confused when the log message began with certain
+   strings that looked like Subject:, Date: or From: header.
+
+ * "git reset" accidentally run in .git/ directory checked out the
+   work tree contents in there.
+
+
+Other minor documentation updates are included.

+Git v1.6.5.6 Release Notes
+==========================
+
+Fixes since v1.6.5.5
+--------------------
+
+ * "git add -p" had a regression since v1.6.5.3 that broke deletion of
+   non-empty files.
+
+ * "git archive -o o.zip -- Makefile" produced an archive in o.zip
+   but in POSIX tar format.
+
+ * Error message given to "git pull --rebase" when the user didn't give
+   enough clue as to what branch to integrate with still talked about
+   "merging with" the branch.
+
+ * Error messages given by "git merge" when the merge resulted in a
+   fast-forward still were in plumbing lingo, even though in v1.6.5
+   we reworded messages in other cases.
+
+ * The post-upload-hook run by upload-pack in response to "git fetch" has
+   been removed, due to security concerns (the hook first appeared in
+   1.6.5).

+GIT v1.6.5 Release Notes
+========================
+
+In git 1.7.0, which was planned to be the release after 1.6.5, "git
+push" into a branch that is currently checked out will be refused by
+default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyCurrentBranch in the receiving
+repository.
+
+Also, "git push $there :$killed" to delete the branch $killed in a remote
+repository $there, when $killed branch is the current branch pointed at by
+its HEAD, will be refused by default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyDeleteCurrent in the receiving
+repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing.  Please refer to:
+
+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+Updates since v1.6.4
+--------------------
+
+(subsystems)
+
+ * various updates to gitk, git-svn and gitweb.
+
+(portability)
+
+ * more improvements on mingw port.
+
+ * mingw will also give FRSX as the default value for the LESS
+   environment variable when the user does not have one.
+
+ * initial support to compile git on Windows with MSVC.
+
+(performance)
+
+ * On major platforms, the system can be compiled to use with Linus's
+   block-sha1 implementation of the SHA-1 hash algorithm, which
+   outperforms the default fallback implementation we borrowed from
+   Mozilla.
+
+ * Unnecessary inefficiency in deepening of a shallow repository has
+   been removed.
+
+ * "git clone" does not grab objects that it does not need (i.e.
+   referenced only from refs outside refs/heads and refs/tags
+   hierarchy) anymore.
+
+ * The "git" main binary used to link with libcurl, which then dragged
+   in a large number of external libraries.  When using basic plumbing
+   commands in scripts, this unnecessarily slowed things down.  We now
+   implement http/https/ftp transfer as a separate executable as we
+   used to.
+
+ * "git clone" run locally hardlinks or copies the files in .git/ to
+   newly created repository.  It used to give new mtime to copied files,
+   but this delayed garbage collection to trigger unnecessarily in the
+   cloned repository.  We now preserve mtime for these files to avoid
+   this issue.
+
+(usability, bells and whistles)
+
+ * Human writable date format to various options, e.g. --since=yesterday,
+   master@{2000.09.17}, are taught to infer some omitted input properly.
+
+ * A few programs gave verbose "advice" messages to help uninitiated
+   people when issuing error messages.  An infrastructure to allow
+   users to squelch them has been introduced, and a few such messages
+   can be silenced now.
+
+ * refs/replace/ hierarchy is designed to be usable as a replacement
+   of the "grafts" mechanism, with the added advantage that it can be
+   transferred across repositories.
+
+ * "git am" learned to optionally ignore whitespace differences.
+
+ * "git am" handles input e-mail files that has CRLF line endings sensibly.
+
+ * "git am" learned "--scissors" option to allow you to discard early part
+   of an incoming e-mail.
+
+ * "git archive -o output.zip" works without being told what format to
+   use with an explicit "--format=zip".option.
+
+ * "git checkout", "git reset" and "git stash" learned to pick and
+   choose to use selected changes you made, similar to "git add -p".
+
+ * "git clone" learned a "-b" option to pick a HEAD to check out
+   different from the remote's default branch.
+
+ * "git clone" learned --recursive option.
+
+ * "git clone" from a local repository on a different filesystem used to
+   copy individual object files without preserving the old timestamp, giving
+   them extra lifetime in the new repository until they gc'ed.
+
+ * "git commit --dry-run $args" is a new recommended way to ask "what would
+   happen if I try to commit with these arguments."
+
+ * "git commit --dry-run" and "git status" shows conflicted paths in a
+   separate section to make them easier to spot during a merge.
+
+ * "git cvsimport" now supports password-protected pserver access even
+   when the password is not taken from ~/.cvspass file.
+
+ * "git fast-export" learned --no-data option that can be useful when
+   reordering commits and trees without touching the contents of
+   blobs.
+
+ * "git fast-import" has a pair of new front-end in contrib/ area.
+
+ * "git init" learned to mkdir/chdir into a directory when given an
+   extra argument (i.e. "git init this").
+
+ * "git instaweb" optionally can use mongoose as the web server.
+
+ * "git log --decorate" can optionally be told with --decorate=full to
+   give the reference name in full.
+
+ * "git merge" issued an unnecessarily scary message when it detected
+   that the merge may have to touch the path that the user has local
+   uncommitted changes to. The message has been reworded to make it
+   clear that the command aborted, without doing any harm.
+
+ * "git push" can be told to be --quiet.
+
+ * "git push" pays attention to url.$base.pushInsteadOf and uses a URL
+   that is derived from the URL used for fetching.
+
+ * informational output from "git reset" that lists the locally modified
+   paths is made consistent with that of "git checkout $another_branch".
+
+ * "git submodule" learned to give submodule name to scripts run with
+   "foreach" subcommand.
+
+ * various subcommands to "git submodule" learned --recursive option.
+
+ * "git submodule summary" learned --files option to compare the work
+   tree vs the commit bound at submodule path, instead of comparing
+   the index.
+
+ * "git upload-pack", which is the server side support for "git clone" and
+   "git fetch", can call a new post-upload-pack hook for statistics purposes.
+
+(developers)
+
+ * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
+   source directory; using tmpfs may give faster turnaround.
+
+ * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
+   build for one location, and install into another location to tar it
+   up.
+
+Fixes since v1.6.4
+------------------
+
+All of the fixes in v1.6.4.X maintenance series are included in this
+release, unless otherwise noted.

+Git v1.6.6 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * In this release, "git fsck" defaults to "git fsck --full" and
+   checks packfiles, and because of this it will take much longer to
+   complete than before.  If you prefer a quicker check only on loose
+   objects (the old default), you can say "git fsck --no-full".  This
+   has been supported by 1.5.4 and newer versions of git, so it is
+   safe to write it in your script even if you use slightly older git
+   on some of your machines.
+
+Preparing yourselves for compatibility issues in 1.7.0
+------------------------------------------------------
+
+In git 1.7.0, which is planned to be the release after 1.6.6, there will
+be a handful of behaviour changes that will break backward compatibility.
+
+These changes were discussed long time ago and existing behaviours have
+been identified as more problematic to the userbase than keeping them for
+the sake of backward compatibility.
+
+When necessary, a transition strategy for existing users has been designed
+not to force them running around setting configuration variables and
+updating their scripts in order to either keep the traditional behaviour
+or adjust to the new behaviour, on the day their sysadmin decides to install
+the new version of git.  When we switched from "git-foo" to "git foo" in
+1.6.0, even though the change had been advertised and the transition
+guide had been provided for a very long time, the users procrastinated
+during the entire transition period, and ended up panicking on the day
+their sysadmins updated their git installation.  We are trying to avoid
+repeating that unpleasantness in the 1.7.0 release.
+
+For changes decided to be in 1.7.0, commands that will be affected
+have been much louder to strongly discourage such procrastination, and
+they continue to be in this release.  If you have been using recent
+versions of git, you would have seen warnings issued when you used
+features whose behaviour will change, with a clear instruction on how
+to keep the existing behaviour if you want to.  You hopefully are
+already well prepared.
+
+Of course, we have also been giving "this and that will change in
+1.7.0; prepare yourselves" warnings in the release notes and
+announcement messages for the past few releases.  Let's see how well
+users will fare this time.
+
+ * "git push" into a branch that is currently checked out (i.e. pointed by
+   HEAD in a repository that is not bare) will be refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.  Versions of git
+   since 1.6.2 have issued a loud warning when you tried to do these
+   operations without setting the configuration, so repositories of
+   people who still need to be able to perform such a push should
+   already have been future proofed.
+
+   Please refer to:
+
+   http://git.or.cz/gitwiki/GitFaq#non-bare
+   http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+   for more details on the reason why this change is needed and the
+   transition process that already took place so far.
+
+ * "git send-email" will not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.  Git 1.6.6 (this
+   release) will issue a warning about the upcoming default change, when
+   it uses the traditional "deep threading" behaviour as the built-in
+   default.  To squelch the warning but still use the "deep threading"
+   behaviour, give --chain-reply-to option or set sendemail.chainreplyto
+   to true.
+
+   It has been possible to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.
+   The only thing 1.7.0 release will do is to change the default when
+   you haven't configured that variable.
+
+ * "git status" will not be "git commit --dry-run".  This change does not
+   affect you if you run the command without pathspec.
+
+   Nobody sane found the current behaviour of "git status Makefile" useful
+   nor meaningful, and it confused users.  "git commit --dry-run" has been
+   provided as a way to get the current behaviour of this command since
+   1.6.5.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   amount of whitespace and nothing else.  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In 1.7.0, the "ignore whitespaces" will affect the semantics of the
+   diff operation itself.  A change that does not affect anything but
+   whitespaces will be reported with zero exit status when run with
+   --exit-code, and there will not be "diff --git" header for such a
+   change.
+
+
+Updates since v1.6.5
+--------------------
+
+(subsystems)
+
+ * various gitk updates including use of themed widgets under Tk 8.5,
+   Japanese translation, a fix to a bug when running "gui blame" from
+   a subdirectory, etc.
+
+ * various git-gui updates including new translations, wm states fixes,
+   Tk bug workaround after quitting, improved heuristics to trigger gc,
+   etc.
+
+ * various git-svn updates.
+
+ * "git fetch" over http learned a new mode that is different from the
+   traditional "dumb commit walker".
+
+(portability)
+
+ * imap-send can be built on mingw port.
+
+(performance)
+
+ * "git diff -B" has smaller memory footprint.
+
+(usability, bells and whistles)
+
+ * The object replace mechanism can be bypassed with --no-replace-objects
+   global option given to the "git" program.
+
+ * In configuration files, a few variables that name paths can begin with ~/
+   and ~username/ and they are expanded as expected.
+
+ * "git subcmd -h" now shows short usage help for many more subcommands.
+
+ * "git bisect reset" can reset to an arbitrary commit.
+
+ * "git checkout frotz" when there is no local branch "frotz" but there
+   is only one remote tracking branch "frotz" is taken as a request to
+   start the named branch at the corresponding remote tracking branch.
+
+ * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
+   to ignore authorship information in the commit it is taking the message
+   from.
+
+ * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
+
+ * "git diff" learned --submodule option to show a list of one-line logs
+   instead of differences between the commit object names.
+
+ * "git diff" learned to honor diff.color.func configuration to paint
+   function name hint printed on the hunk header "@@ -j,k +l,m @@" line
+   in the specified color.
+
+ * "git fetch" learned --all and --multiple options, to run fetch from
+   many repositories, and --prune option to remove remote tracking
+   branches that went stale.  These make "git remote update" and "git
+   remote prune" less necessary (there is no plan to remove "remote
+   update" nor "remote prune", though).
+
+ * "git fsck" by default checks the packfiles (i.e. "--full" is the
+   default); you can turn it off with "git fsck --no-full".
+
+ * "git grep" can use -F (fixed strings) and -i (ignore case) together.
+
+ * import-tars contributed fast-import frontend learned more types of
+   compressed tarballs.
+
+ * "git instaweb" knows how to talk with mod_cgid to apache2.
+
+ * "git log --decorate" shows the location of HEAD as well.
+
+ * "git log" and "git rev-list" learned to take revs and pathspecs from
+   the standard input with the new "--stdin" option.
+
+ * "--pretty=format" option to "log" family of commands learned:
+
+   . to wrap text with the "%w()" specifier.
+   . to show reflog information with "%g[sdD]" specifier.
+
+ * "git notes" command to annotate existing commits.
+
+ * "git merge" (and "git pull") learned --ff-only option to make it fail
+   if the merge does not result in a fast-forward.
+
+ * "git mergetool" learned to use p4merge.
+
+ * "git rebase -i" learned "reword" that acts like "edit" but immediately
+   starts an editor to tweak the log message without returning control to
+   the shell, which is done by "edit" to give an opportunity to tweak the
+   contents.
+
+ * "git send-email" can be told with "--envelope-sender=auto" to use the
+   same address as "From:" address as the envelope sender address.
+
+ * "git send-email" will issue a warning when it defaults to the
+   --chain-reply-to behaviour without being told by the user and
+   instructs to prepare for the change of the default in 1.7.0 release.
+
+ * In "git submodule add <repository> <path>", <path> is now optional and
+   inferred from <repository> the same way "git clone <repository>" does.
+
+ * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
+
+ * "git svn" learned to recreate empty directories tracked only by SVN.
+
+ * "gitweb" can optionally render its "blame" output incrementally (this
+   requires JavaScript on the client side).
+
+ * Author names shown in gitweb output are links to search commits by the
+   author.
+
+Fixes since v1.6.5
+------------------
+
+All of the fixes in v1.6.5.X maintenance series are included in this
+release, unless otherwise noted.

+Git v1.7.0.1 Release Notes
+==========================
+
+Fixes since v1.7.0
+------------------
+
+ * In a freshly created repository "rev-parse HEAD^0" complained that
+   it is dangling symref, even though "rev-parse HEAD" didn't.
+
+ * "git show :no-such-name" tried to access the index without bounds
+   check, leading to a potential segfault.
+
+ * Message from "git cherry-pick" was harder to read and use than necessary
+   when it stopped due to conflicting changes.
+
+ * We referred to ".git/refs/" throughout the documentation when we
+   meant to talk about abstract notion of "ref namespace".  Because
+   people's repositories often have packed refs these days, this was
+   confusing.
+
+ * "git diff --output=/path/that/cannot/be/written" did not correctly
+   error out.
+
+ * "git grep -e -pattern-that-begin-with-dash paths..." could not be
+   spelled as "git grep -- -pattern-that-begin-with-dash paths..." which
+   would be a GNU way to use "--" as "end of options".
+
+ * "git grep" compiled with threading support tried to access an
+   uninitialized mutex on boxes with a single CPU.
+
+ * "git stash pop -q --index" failed because the unnecessary --index
+   option was propagated to "git stash drop" that is internally run at the
+   end.
+
+And other minor fixes and documentation updates.

+Git v1.7.0.2 Release Notes
+==========================
+
+Fixes since v1.7.0.1
+--------------------
+
+ * GIT_PAGER was not honored consistently by some scripted Porcelains, most
+   notably "git am".
+
+ * updating working tree files after telling git to add them to the
+   index and while it is still working created garbage object files in
+   the repository without diagnosing it as an error.
+
+ * "git bisect -- pathspec..." did not diagnose an error condition properly when
+   the simplification with given pathspec made the history empty.
+
+ * "git rev-list --cherry-pick A...B" now has an obvious optimization when the
+   histories haven't diverged (i.e. when one end is an ancestor of the other).
+
+ * "git diff --quiet -w" did not work as expected.
+
+ * "git fast-import" didn't work with a large input, as it lacked support
+   for producing the pack index in v2 format.
+
+ * "git imap-send" didn't use CRLF line endings over the imap protocol
+   when storing its payload to the draft box, violating RFC 3501.
+
+ * "git log --format='%w(x,y,z)%b'" and friends that rewrap message
+   has been optimized for utf-8 payload.
+
+ * Error messages generated on the receiving end did not come back to "git
+   push".
+
+ * "git status" in 1.7.0 lacked the optimization we used to have in 1.6.X series
+   to speed up scanning of large working tree.
+
+ * "gitweb" did not diagnose parsing errors properly while reading tis configuration
+   file.

+Git v1.7.0 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * "git push" into a branch that is currently checked out (i.e. pointed at by
+   HEAD in a repository that is not bare) is refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.
+
+ * "git send-email" does not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.
+
+   It has been possible already to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.  The
+   only thing this release does is to change the default when you haven't
+   configured that variable.
+
+ * "git status" is not "git commit --dry-run" anymore.  This change does
+   not affect you if you run the command without argument.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   amount of whitespace and nothing else;  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In this release, the "ignore whitespaces" options affect the semantics
+   of the diff operation.  A change that does not affect anything but
+   whitespaces is reported with zero exit status when run with
+   --exit-code, and there is no "diff --git" header for such a change.
+
+ * External diff and textconv helpers are now executed using the shell.
+   This makes them consistent with other programs executed by git, and
+   allows you to pass command-line parameters to the helpers. Any helper
+   paths containing spaces or other metacharacters now need to be
+   shell-quoted.  The affected helpers are GIT_EXTERNAL_DIFF in the
+   environment, and diff.*.command and diff.*.textconv in the config
+   file.
+
+ * The --max-pack-size argument to 'git repack', 'git pack-objects', and
+   'git fast-import' was assuming the provided size to be expressed in MiB,
+   unlike the corresponding config variable and other similar options accepting
+   a size value.  It is now expecting a size expressed in bytes, with a possible
+   unit suffix of 'k', 'm', or 'g'.
+
+Updates since v1.6.6
+--------------------
+
+(subsystems)
+
+ * "git fast-import" updates; adds "option" and "feature" to detect the
+   mismatch between fast-import and the frontends that produce the input
+   stream.
+
+ * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
+
+ * "gitk" and "git gui" translation updates.
+
+ * "gitweb" updates (code clean-up, load checking etc.)
+
+(portability)
+
+ * Some more MSVC portability patches for msysgit port.
+
+ * Minimum Pthreads emulation for msysgit port.
+
+(performance)
+
+ * More performance improvement patches for msysgit port.
+
+(usability, bells and whistles)
+
+ * More commands learned "--quiet" and "--[no-]progress" options.
+
+ * Various commands given by the end user (e.g. diff.type.textconv,
+   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
+   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
+
+ * "sparse checkout" feature allows only part of the work tree to be
+   checked out.
+
+ * HTTP transfer can use authentication scheme other than basic
+   (i.e./e.g. digest).
+
+ * Switching from a version of superproject that used to have a submodule
+   to another version of superproject that no longer has it did not remove
+   the submodule directory when it should (namely, when you are not
+   interested in the submodule at all and didn't clone/checkout).
+
+ * A new attribute conflict-marker-size can be used to change the size of
+   the conflict markers from the default 7; this is useful when tracked
+   contents (e.g. git-merge documentation) have strings that resemble the
+   conflict markers.
+
+ * A new syntax "<branch>@{upstream}" can be used on the command line to
+   substitute the name of the "upstream" of the branch.  Missing branch
+   defaults to the current branch, so "git fetch && git merge @{upstream}"
+   will be equivalent to "git pull".
+
+ * "git am --resolved" has a synonym "git am --continue".
+
+ * "git branch --set-upstream" can be used to update the (surprise!) upstream,
+   i.e. where the branch is supposed to pull and merge from (or rebase onto).
+
+ * "git checkout A...B" is a way to detach HEAD at the merge base between
+   A and B.
+
+ * "git checkout -m path" to reset the work tree file back into the
+   conflicted state works even when you already ran "git add path" and
+   resolved the conflicts.
+
+ * "git commit --date='<date>'" can be used to override the author date
+   just like "git commit --author='<name> <email>'" can be used to
+   override the author identity.
+
+ * "git commit --no-status" can be used to omit the listing of the index
+   and the work tree status in the editor used to prepare the log message.
+
+ * "git commit" warns a bit more aggressively until you configure user.email,
+   whose default value almost always is not (and fundamentally cannot be)
+   what you want.
+
+ * "git difftool" has been extended to make it easier to integrate it
+   with gitk.
+
+ * "git fetch --all" can now be used in place of "git remote update".
+
+ * "git grep" does not rely on external grep anymore.  It can use more than
+   one thread to accelerate the operation.
+
+ * "git grep" learned "--quiet" option.
+
+ * "git log" and friends learned "--glob=heads/*" syntax that is a more
+   flexible way to complement "--branches/--tags/--remotes".
+
+ * "git merge" learned to pass options specific to strategy-backends.  E.g.
+
+    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
+      strategy how much to shift the trees explicitly.
+
+    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
+      while discarding your own changes and taking merged version in
+      conflicted regions.
+
+ * "git push" learned "git push origin --delete branch", a syntactic sugar
+   for "git push origin :branch".
+
+ * "git push" learned "git push --set-upstream origin forker:forkee" that
+   lets you configure your "forker" branch to later pull from "forkee"
+   branch at "origin".
+
+ * "git rebase --onto A...B" means the history is replayed on top of the
+   merge base between A and B.
+
+ * "git rebase -i" learned new action "fixup" that squashes the change
+   but does not affect existing log message.
+
+ * "git rebase -i" also learned --autosquash option that is useful
+   together with the new "fixup" action.
+
+ * "git remote" learned set-url subcommand that updates (surprise!) url
+   for an existing remote nickname.
+
+ * "git rerere" learned "forget path" subcommand.  Together with "git
+   checkout -m path" it will be useful when you recorded a wrong
+   resolution.
+
+ * Use of "git reset --merge" has become easier when resetting away a
+   conflicted mess left in the work tree.
+
+ * "git rerere" had rerere.autoupdate configuration but there was no way
+   to countermand it from the command line; --no-rerere-autoupdate option
+   given to "merge", "revert", etc. fixes this.
+
+ * "git status" learned "-s(hort)" output format.
+
+(developers)
+
+ * The infrastructure to build foreign SCM interface has been updated.
+
+ * Many more commands are now built-in.
+
+ * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
+   compression will always take advantage of it.
+
+Fixes since v1.6.6
+------------------
+
+All of the fixes in v1.6.6.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git branch -d branch" used to refuse deleting the branch even when
+   the branch is fully merged to its upstream branch if it is not merged
+   to the current branch.  It now deletes it in such a case.
+
+ * "filter-branch" command incorrectly said --prune-empty and --filter-commit
+   were incompatible; the latter should be read as --commit-filter.
+
+ * When using "git status" or asking "git diff" to compare the work tree
+   with something, they used to consider that a checked-out submodule with
+   uncommitted changes is not modified; this could cause people to forget
+   committing these changes in the submodule before committing in the
+   superproject. They now consider such a change as a modification and
+   "git diff" will append a "-dirty" to the work tree side when generating
+   patch output or when used with the --submodule option.

+Git v1.7.1.1 Release Notes
+==========================
+
+Fixes since v1.7.1
+------------------
+
+ * Authentication over http transport can now be made lazily, in that the
+   request can first go to a URL without username, get a 401 response and
+   then the client will ask for the username to use.
+
+ * We used to mistakenly think "../work" is a subdirectory of the current
+   directory when we are in "../work-xyz".
+
+ * The attribute mechanism now allows an entry that uses an attribute
+   macro that set/unset one attribute, immediately followed by an
+   overriding setting; this makes attribute macros much easier to use.
+
+ * We didn't recognize timezone "Z" as a synonym for "UTC" (75b37e70).
+
+ * In 1.7.0, read-tree and user commands that use the mechanism such as
+   checkout and merge were fixed to handle switching between branches one
+   of which has a file while the other has a directory at the same path
+   correctly even when there are some "confusing" pathnames in them.  But
+   the algorithm used for this fix was suboptimal and had a terrible
+   performance degradation especially in larger trees.
+
+ * "git am -3" did not show diagnosis when the patch in the message was corrupt.
+
+ * After "git apply --whitespace=fix" removed trailing blank lines in an
+   patch in a patch series, it failed to apply later patches that depend
+   on the presence of such blank lines.
+
+ * "git bundle --stdin" segfaulted.
+
+ * "git checkout" and "git rebase" overwrote paths that are marked "assume
+   unchanged".
+
+ * "git commit --amend" on a commit with an invalid author-name line that
+   lacks the display name didn't work.
+
+ * "git describe" did not tie-break tags that point at the same commit
+   correctly; newer ones are preferred by paying attention to the
+   tagger date now.
+
+ * "git diff" used to tell underlying xdiff machinery to work very hard to
+   minimize the output, but this often was spending too many extra cycles
+   for very little gain.
+
+ * "git diff --color" did not paint extended diff headers per line
+   (i.e. the coloring escape sequence didn't end at the end of line),
+   which confused "less -R".
+
+ * "git fetch" over HTTP verifies the downloaded packfiles more robustly.
+
+ * The memory usage by "git index-pack" (run during "git fetch" and "git
+   push") got leaner.
+
+ * "GIT_DIR=foo.git git init --bare bar.git" created foo.git instead of bar.git.
+
+ * "git log --abbrev=$num --format='%h' ignored --abbrev=$num.
+
+ * "git ls-files ../out/side/cwd" refused to work.
+
+ * "git merge --log" used to replace the custom message given by "-m" with
+   the shortlog, instead of appending to it.
+
+ * "git notes copy" without any other argument segfaulted.
+
+ * "git pull" accepted "--dry-run", gave it to underlying "git fetch" but
+   ignored the option itself, resulting in a bogus attempt to merge
+   unrelated commit.
+
+ * "git rebase" did not faithfully reproduce a malformed author ident, that
+   is often seen in a repository converted from foreign SCMs.
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+   a nonstandard location is in use got confused.
+
+ * "git send-email" lacked a way to specify the domainname used in the
+   EHLO/HELO exchange, causing rejected connection from picky servers.
+   It learned --smtp-domain option to solve this issue.
+
+ * "git send-email" did not declare a content-transfer-encoding and
+   content-type even when its payload needs to be sent in 8-bit.
+
+ * "git show -C -C" and other corner cases lost diff metainfo output
+   in 1.7.0.
+
+ * "git stash" incorrectly lost paths in the working tree that were
+   previously removed from the index.
+
+ * "git status" stopped refreshing the index by mistake in 1.7.1.
+
+ * "git status" showed excess "hints" even when advice.statusHints is set to false.
+
+And other minor fixes and documentation updates.

+Git v1.7.1 Release Notes
+========================
+
+Updates since v1.7.0
+--------------------
+
+ * Eric Raymond is the maintainer of updated CIAbot scripts, in contrib/.
+
+ * gitk updates.
+
+ * Some commands (e.g. svn and http interfaces) that interactively ask
+   for a password can be told to use an external program given via
+   GIT_ASKPASS.
+
+ * Conflict markers that lead the common ancestor in diff3-style output
+   now have a label, which hopefully would help third-party tools that
+   expect one.
+
+ * Comes with an updated bash-completion script.
+
+ * "git am" learned "--keep-cr" option to handle inputs that are
+   a mixture of changes to files with and without CRLF line endings.
+
+ * "git cvsimport" learned -R option to leave revision mapping between
+   CVS revisions and resulting git commits.
+
+ * "git diff --submodule" notices and describes dirty submodules.
+
+ * "git for-each-ref" learned %(symref), %(symref:short) and %(flag)
+   tokens.
+
+ * "git hash-object --stdin-paths" can take "--no-filters" option now.
+
+ * "git init" can be told to look at init.templatedir configuration
+   variable (obviously that has to come from either /etc/gitconfig or
+   $HOME/.gitconfig).
+
+ * "git grep" learned "--no-index" option, to search inside contents that
+   are not managed by git.
+
+ * "git grep" learned --color=auto/always/never.
+
+ * "git grep" learned to paint filename and line-number in colors.
+
+ * "git log -p --first-parent -m" shows one-parent diff for merge
+   commits, instead of showing combined diff.
+
+ * "git merge-file" learned to use custom conflict marker size and also
+   to use the "union merge" behaviour.
+
+ * "git notes" command has been rewritten in C and learned many commands
+   and features to help you carry notes forward across rebases and amends.
+
+ * "git request-pull" identifies the commit the request is relative to in
+   a more readable way.
+
+ * "git reset" learned "--keep" option that lets you discard commits
+   near the tip while preserving your local changes in a way similar
+   to how "git checkout branch" does.
+
+ * "git status" notices and describes dirty submodules.
+
+ * "git svn" should work better when interacting with repositories
+   with CRLF line endings.
+
+ * "git imap-send" learned to support CRAM-MD5 authentication.
+
+ * "gitweb" installation procedure can use "minified" js/css files
+   better.
+
+ * Various documentation updates.
+
+Fixes since v1.7.0
+------------------
+
+All of the fixes in v1.7.0.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git add frotz/nitfol" did not complain when the entire frotz/ directory
+   was ignored.
+
+ * "git diff --stat" used "int" to count the size of differences,
+   which could result in overflowing.
+
+ * "git rev-list --pretty=oneline" didn't terminate a record with LF for
+   commits without any message.
+
+ * "git rev-list --abbrev-commit" defaulted to 40-byte abbreviations, unlike
+   newer tools in the git toolset.

+Git v1.7.10.1 Release Notes
+===========================
+
+Additions since v1.7.10
+-----------------------
+
+Localization message files for Danish and German have been added.
+
+
+Fixes since v1.7.10
+-------------------
+
+ * "git add -p" is not designed to deal with unmerged paths but did
+   not exclude them and tried to apply funny patches only to fail.
+
+ * "git blame" started missing quite a few changes from the origin
+   since we stopped using the diff minimization by default in v1.7.2
+   era.
+
+ * When PATH contains an unreadable directory, alias expansion code
+   did not kick in, and failed with an error that said "git-subcmd"
+   was not found.
+
+ * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
+   working trees of independent git repositories that exist in the
+   current project working tree from getting removed, but the
+   protection applied only to such working trees that are at the
+   top-level of the current project by mistake.
+
+ * "git commit --author=$name" did not tell the name that was being
+   recorded in the resulting commit to hooks, even though it does do
+   so when the end user overrode the authorship via the
+   "GIT_AUTHOR_NAME" environment variable.
+
+ * When "git commit --template F" errors out because the user did not
+   touch the message, it claimed that it aborts due to "empty
+   message", which was utterly wrong.
+
+ * The regexp configured with diff.wordregex was incorrectly reused
+   across files.
+
+ * An age-old corner case bug in combine diff (only triggered with -U0
+   and the hunk at the beginning of the file needs to be shown) has
+   been fixed.
+
+ * Rename detection logic used to match two empty files as renames
+   during merge-recursive, leading to unnatural mismerges.
+
+ * The parser in "fast-import" did not diagnose ":9" style references
+   that is not followed by required SP/LF as an error.
+
+ * When "git fetch" encounters repositories with too many references,
+   the command line of "fetch-pack" that is run by a helper
+   e.g. remote-curl, may fail to hold all of them. Now such an
+   internal invocation can feed the references through the standard
+   input of "fetch-pack".
+
+ * "git fetch" that recurses into submodules on demand did not check
+   if it needs to go into submodules when non branches (most notably,
+   tags) are fetched.
+
+ * "log -p --graph" used with "--stat" had a few formatting error.
+
+ * Running "notes merge --commit" failed to perform correctly when run
+   from any directory inside $GIT_DIR/.  When "notes merge" stops with
+   conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
+   to resolve it.
+
+ * The 'push to upstream' implementation was broken in some corner
+   cases. "git push $there" without refspec, when the current branch
+   is set to push to a remote different from $there, used to push to
+   $there using the upstream information to a remote unreleated to
+   $there.
+
+ * Giving "--continue" to a conflicted "rebase -i" session skipped a
+   commit that only results in changes to submodules.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.2 Release Notes
+===========================
+
+Fixes since v1.7.10.1
+---------------------
+
+ * The test scaffolding for git-daemon was flaky.
+
+ * The test scaffolding for fast-import was flaky.
+
+ * The filesystem boundary was not correctly reported when .git directory
+   discovery stopped at a mount point.
+
+ * HTTP transport that requires authentication did not work correctly when
+   multiple connections are used simultaneously.
+
+ * Minor memory leak during unpack_trees (hence "merge" and "checkout"
+   to check out another branch) has been plugged.
+
+ * In the older days, the header "Conflicts:" in "cherry-pick" and "merge"
+   was separated by a blank line from the list of paths that follow for
+   readability, but when "merge" was rewritten in C, we lost it by
+   mistake. Remove the newline from "cherry-pick" to make them match
+   again.
+
+ * The command line parser choked "git cherry-pick $name" when $name can
+   be both revision name and a pathname, even though $name can never be a
+   path in the context of the command.
+
+ * The "include.path" facility in the configuration mechanism added in
+   1.7.10 forgot to interpret "~/path" and "~user/path" as it should.
+
+ * "git config --rename-section" to rename an existing section into a
+   bogus one did not check the new name.
+
+ * The "diff --no-index" codepath used limited-length buffers, risking
+   pathnames getting truncated.  Update it to use the strbuf API.
+
+ * The report from "git fetch" said "new branch" even for a non branch
+   ref.
+
+ * The http-backend (the server side of the smart http transfer) used
+   to overwrite GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL with the
+   value obtained from REMOTE_USER unconditionally, making it
+   impossible for the server side site-specific customization to use
+   different identity sources to affect the names logged. It now uses
+   REMOTE_USER only as a fallback value.
+
+ * "log --graph" was not very friendly with "--stat" option and its
+   output had line breaks at wrong places.
+
+ * Octopus merge strategy did not reduce heads that are recorded in the
+   final commit correctly.
+
+ * "git push" over smart-http lost progress output a few releases ago;
+   this release resurrects it.
+
+ * The error and advice messages given by "git push" when it fails due
+   to non-ff were not very helpful to new users; it has been broken
+   into three cases, and each is given a separate advice message.
+
+ * The insn sheet given by "rebase -i" did not make it clear that the
+   insn lines can be re-ordered to affect the order of the commits in
+   the resulting history.
+
+ * "git repack" used to write out unreachable objects as loose objects
+   when repacking, even if such loose objects will immediately pruned
+   due to its age.
+
+ * A contrib script "rerere-train" did not work out of the box unless
+   user futzed with her $PATH.
+
+ * "git rev-parse --show-prefix" used to emit nothing when run at the
+   top-level of the working tree, but now it gives a blank line.
+
+ * The i18n of error message "git stash save" was not properly done.
+
+ * "git submodule" used a sed script that some platforms mishandled.
+
+ * When using a Perl script on a system where "perl" found on user's
+   $PATH could be ancient or otherwise broken, we allow builders to
+   specify the path to a good copy of Perl with $PERL_PATH.  The
+   gitweb test forgot to use that Perl when running its test.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.3 Release Notes
+===========================
+
+Fixes since v1.7.10.2
+---------------------
+
+ * The message file for German translation has been updated a bit.
+
+ * Running "git checkout" on an unborn branch used to corrupt HEAD.
+
+ * When checking out another commit from an already detached state, we
+   used to report all commits that are not reachable from any of the
+   refs as lossage, but some of them might be reachable from the new
+   HEAD, and there is no need to warn about them.
+
+ * Some time ago, "git clone" lost the progress output for its
+   "checkout" phase; when run without any "--quiet" option, it should
+   give progress to the lengthy operation.
+
+ * The directory path used in "git diff --no-index", when it recurses
+   down, was broken with a recent update after v1.7.10.1 release.
+
+ * "log -z --pretty=tformat:..." did not terminate each record with
+   NUL.  The fix is not entirely correct when the output also asks for
+   --patch and/or --stat, though.
+
+ * The DWIM behaviour for "log --pretty=format:%gd -g" was somewhat
+   broken and gave undue precedence to configured log.date, causing
+   "git stash list" to show "stash@{time stamp string}".
+
+ * "git status --porcelain" ignored "--branch" option by mistake.  The
+   output for "git status --branch -z" was also incorrect and did not
+   terminate the record for the current branch name with NUL as asked.
+
+ * When a submodule repository uses alternate object store mechanism,
+   some commands that were started from the superproject did not
+   notice it and failed with "No such object" errors.  The subcommands
+   of "git submodule" command that recursed into the submodule in a
+   separate process were OK; only the ones that cheated and peeked
+   directly into the submodule's repository from the primary process
+   were affected.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10 Release Notes
+=========================
+
+Compatibility Notes
+-------------------
+
+ * From this release on, the "git merge" command in an interactive
+   session will start an editor when it automatically resolves the
+   merge for the user to explain the resulting commit, just like the
+   "git commit" command does when it wasn't given a commit message.
+
+   If you have a script that runs "git merge" and keeps its standard
+   input and output attached to the user's terminal, and if you do not
+   want the user to explain the resulting merge commits, you can
+   export GIT_MERGE_AUTOEDIT environment variable set to "no", like
+   this:
+
+	#!/bin/sh
+	GIT_MERGE_AUTOEDIT=no
+	export GIT_MERGE_AUTOEDIT
+
+   to disable this behavior (if you want your users to explain their
+   merge commits, you do not have to do anything).  Alternatively, you
+   can give the "--no-edit" option to individual invocations of the
+   "git merge" command if you know everybody who uses your script has
+   Git v1.7.8 or newer.
+
+ * The "--binary/-b" options to "git am" have been a no-op for quite a
+   while and were deprecated in mid 2008 (v1.6.0).  When you give these
+   options to "git am", it will now warn and ask you not to use them.
+
+ * When you do not tell which branches and tags to push to the "git
+   push" command in any way, the command used "matching refs" rule to
+   update remote branches and tags with branches and tags with the
+   same name you locally have.  In future versions of Git, this will
+   change to push out only your current branch according to either the
+   "upstream" or the "current" rule.  Although "upstream" may be more
+   powerful once the user understands Git better, the semantics
+   "current" gives is simpler and easier to understand for beginners
+   and may be a safer and better default option.  We haven't decided
+   yet which one to switch to.
+
+
+Updates since v1.7.9
+--------------------
+
+UI, Workflows & Features
+
+ * various "gitk" updates.
+   - show the path to the top level directory in the window title
+   - update preference edit dialog
+   - display file list correctly when directories are given on command line
+   - make "git-describe" output in the log message into a clickable link
+   - avoid matching the UNIX timestamp part when searching all fields
+   - give preference to symbolic font names like sans & monospace
+   - allow comparing two commits using a mark
+   - "gitk" honors log.showroot configuration.
+
+ * Teams for localizing the messages from the Porcelain layer of
+   commands are starting to form, thanks to Jiang Xin who volunteered
+   to be the localization coordinator.  Translated messages for
+   simplified Chinese, Swedish and Portuguese are available.
+
+ * The configuration mechanism learned an "include" facility; an
+   assignment to the include.path pseudo-variable causes the named
+   file to be included in-place when Git looks up configuration
+   variables.
+
+ * A content filter (clean/smudge) used to be just a way to make the
+   recorded contents "more useful", and allowed to fail; a filter can
+   now optionally be marked as "required".
+
+ * Options whose names begin with "--no-" (e.g. the "--no-verify"
+   option of the "git commit" command) can be negated by omitting
+   "no-" from its name, e.g. "git commit --verify".
+
+ * "git am" learned to pass "-b" option to underlying "git mailinfo", so
+   that a bracketed string other than "PATCH" at the beginning can be kept.
+
+ * "git clone" learned "--single-branch" option to limit cloning to a
+   single branch (surprise!); tags that do not point into the history
+   of the branch are not fetched.
+
+ * "git clone" learned to detach the HEAD in the resulting repository
+   when the user specifies a tag with "--branch" (e.g., "--branch=v1.0").
+   Clone also learned to print the usual "detached HEAD" advice in such
+   a case, similar to "git checkout v1.0".
+
+ * When showing a patch while ignoring whitespace changes, the context
+   lines are taken from the postimage, in order to make it easier to
+   view the output.
+
+ * "git diff --stat" learned to adjust the width of the output on
+   wider terminals, and give more columns to pathnames as needed.
+
+ * "diff-highlight" filter (in contrib/) was updated to produce more
+   aesthetically pleasing output.
+
+ * "fsck" learned "--no-dangling" option to omit dangling object
+   information.
+
+ * "git log -G" and "git log -S" learned to pay attention to the "-i"
+   option.  With "-i", "log -G" ignores the case when finding patch
+   hunks that introduce or remove a string that matches the given
+   pattern.  Similarly with "-i", "log -S" ignores the case when
+   finding the commit the given block of text appears or disappears
+   from the file.
+
+ * "git merge" in an interactive session learned to spawn the editor
+   by default to let the user edit the auto-generated merge message,
+   to encourage people to explain their merges better. Legacy scripts
+   can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior.
+   Both "git merge" and "git pull" can be given --no-edit from the
+   command line to accept the auto-generated merge message.
+
+ * The advice message given when the user didn't give enough clue on
+   what to merge to "git pull" and "git merge" has been updated to
+   be more concise and easier to understand.
+
+ * "git push" learned the "--prune" option, similar to "git fetch".
+
+ * The whole directory that houses a top-level superproject managed by
+   "git submodule" can be moved to another place.
+
+ * "git symbolic-ref" learned the "--short" option to abbreviate the
+   refname it shows unambiguously.
+
+ * "git tag --list" can be given "--points-at <object>" to limit its
+   output to those that point at the given object.
+
+ * "gitweb" allows intermediate entries in the directory hierarchy
+   that leads to a project to be clicked, which in turn shows the
+   list of projects inside that directory.
+
+ * "gitweb" learned to read various pieces of information for the
+   repositories lazily, instead of reading everything that could be
+   needed (including the ones that are not necessary for a specific
+   task).
+
+ * Project search in "gitweb" shows the substring that matched in the
+   project name and description highlighted.
+
+ * HTTP transport learned to authenticate with a proxy if needed.
+
+ * A new script "diffall" is added to contrib/; it drives an
+   external tool to perform a directory diff of two Git revisions
+   in one go, unlike "difftool" that compares one file at a time.
+
+Foreign Interface
+
+ * Improved handling of views, labels and branches in "git-p4" (in contrib).
+
+ * "git-p4" (in contrib) suffered from unnecessary merge conflicts when
+   p4 expanded the embedded $RCS$-like keywords; it can be now told to
+   unexpand them.
+
+ * Some "git-svn" updates.
+
+ * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
+   support incremental imports.
+
+ * "git difftool/mergetool" learned to drive DeltaWalker.
+
+Performance
+
+ * Unnecessary calls to parse_object() "git upload-pack" makes in
+   response to "git fetch", have been eliminated, to help performance
+   in repositories with excessive number of refs.
+
+Internal Implementation (please report possible regressions)
+
+ * Recursive call chains in "git index-pack" to deal with long delta
+   chains have been flattened, to reduce the stack footprint.
+
+ * Use of add_extra_ref() API is now gone, to make it possible to
+   cleanly restructure the overall refs API.
+
+ * The command line parser of "git pack-objects" now uses parse-options
+   API.
+
+ * The test suite supports the new "test_pause" helper function.
+
+ * Parallel to the test suite, there is a beginning of performance
+   benchmarking framework.
+
+ * t/Makefile is adjusted to prevent newer versions of GNU make from
+   running tests in seemingly random order.
+
+ * The code to check if a path points at a file beyond a symbolic link
+   has been restructured to be thread-safe.
+
+ * When pruning directories that has become empty during "git prune"
+   and "git prune-packed", call closedir() that iterates over a
+   directory before rmdir() it.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.9
+------------------
+
+Unless otherwise noted, all the fixes since v1.7.9 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * Build with NO_PERL_MAKEMAKER was broken and Git::I18N did not work
+   with versions of Perl older than 5.8.3.
+   (merge 5eb660e ab/perl-i18n later to maint).
+
+ * "git tag -s" honored "gpg.program" configuration variable since
+   1.7.9, but "git tag -v" and "git verify-tag" didn't.
+   (merge a2c2506 az/verify-tag-use-gpg-config later to maint).
+
+ * "configure" script learned to take "--with-sane-tool-path" from the
+   command line to record SANE_TOOL_PATH (used to avoid broken platform
+   tools in /usr/bin) in config.mak.autogen.  This may be useful for
+   people on Solaris who have saner tools outside /usr/xpg[46]/bin.
+
+ * zsh port of bash completion script needed another workaround.

+Git v1.7.11.2 Release Notes
+===========================
+
+Fixes since v1.7.11.1
+---------------------
+
+ * On Cygwin, the platform pread(2) is not thread safe, just like our
+   own compat/ emulation, and cannot be used in the index-pack
+   program.  Makefile variable NO_THREAD_SAFE_PREAD can be defined to
+   avoid use of this function in a threaded program.
+
+ * "git add" allows adding a regular file to the path where a
+   submodule used to exist, but "git update-index" does not allow an
+   equivalent operation to Porcelain writers.
+
+ * "git archive" incorrectly computed the header checksum; the symptom
+   was observed only when using pathnames with hi-bit set.
+
+ * "git blame" did not try to make sure that the abbreviated commit
+   object names in its output are unique.
+
+ * Running "git bundle verify" on a bundle that records a complete
+   history said "it requires these 0 commits".
+
+ * "git clone --single-branch" to clone a single branch did not limit
+   the cloning to the specified branch.
+
+ * "git diff --no-index" did not correctly handle relative paths and
+   did not correctly give exit codes when run under "--quiet" option.
+
+ * "git diff --no-index" did not work with pagers correctly.
+
+ * "git diff COPYING HEAD:COPYING" gave a nonsense error message that
+   claimed that the tree-ish HEAD did not have COPYING in it.
+
+ * When "git log" gets "--simplify-merges/by-decoration" together with
+   "--first-parent", the combination of these options makes the
+   simplification logic to use in-core commit objects that haven't
+   been examined for relevance, either producing incorrect result or
+   taking too long to produce any output.  Teach the simplification
+   logic to ignore commits that the first-parent traversal logic
+   ignored when both are in effect to work around the issue.
+
+ * "git ls-files --exclude=t -i" did not consider anything under t/ as
+   excluded, as it did not pay attention to exclusion of leading paths
+   while walking the index.  Other two users of excluded() are also
+   updated.
+
+ * "git request-pull $url dev" when the tip of "dev" branch was tagged
+   with "ext4-for-linus" used the contents from the tag in the output
+   but still asked the "dev" branch to be pulled, not the tag.
+
+Also contains minor typofixes and documentation updates.

+Git v1.7.11.3 Release Notes
+===========================
+
+Fixes since v1.7.11.3
+---------------------
+
+ * The error message from "git push $there :bogo" (and its equivalent
+   "git push $there --delete bogo") mentioned that we tried and failed
+   to guess what ref is being deleted based on the LHS of the refspec,
+   which we don't.
+
+ * A handful of files and directories we create had tighter than
+   necessary permission bits when the user wanted to have group
+   writability (e.g. by setting "umask 002").
+
+ * "commit --amend" used to refuse amending a commit with an empty log
+   message, with or without "--allow-empty-message".
+
+ * "git commit --amend --only --" was meant to allow "Clever" people to
+   rewrite the commit message without making any change even when they
+   have already changes for the next commit added to their index, but
+   it never worked as advertised since it was introduced in 1.3.0 era.
+
+ * Even though the index can record pathnames longer than 1<<12 bytes,
+   in some places we were not comparing them in full, potentially
+   replacing index entries instead of adding.
+
+ * "git show"'s auto-walking behaviour was an unreliable and
+   unpredictable hack; it now behaves just like "git log" does when it
+   walks.
+
+ * "git diff", "git status" and anything that internally uses the
+   comparison machinery was utterly broken when the difference
+   involved a file with "-" as its name.  This was due to the way "git
+   diff --no-index" was incorrectly bolted on to the system, making
+   any comparison that involves a file "-" at the root level
+   incorrectly read from the standard input.
+
+ * We did not have test to make sure "git rebase" without extra options
+   filters out an empty commit in the original history.
+
+ * "git fast-export" produced an input stream for fast-import without
+   properly quoting pathnames when they contain SPs in them.
+
+ * "git checkout --detach", when you are still on an unborn branch,
+   should be forbidden, but it wasn't.
+
+ * Some implementations of Perl terminates "lines" with CRLF even when
+   the script is operating on just a sequence of bytes.  Make sure to
+   use "$PERL_PATH", the version of Perl the user told Git to use, in
+   our tests to avoid unnecessary breakages in tests.
+
+Also contains minor typofixes and documentation updates.

+Git v1.7.11.4 Release Notes
+===========================

+Fixes since v1.7.11.3
+---------------------
+
+ * "$GIT_DIR/COMMIT_EDITMSG" file that is used to hold the commit log
+   message user edits was not documented.
+
+ * The advise() function did not use varargs correctly to format
+   its message.
+
+ * When "git am" failed, old timers knew to check .git/rebase-apply/patch
+   to see what went wrong, but we never told the users about it.
+
+ * "git commit-tree" learned a more natural "-p <parent> <tree>" order
+   of arguments long time ago, but recently forgot it by mistake.
+
+ * "git diff --no-ext-diff" did not output anything for a typechange
+   filepair when GIT_EXTERNAL_DIFF is in effect.
+
+ * In 1.7.9 era, we taught "git rebase" about the raw timestamp format
+   but we did not teach the same trick to "filter-branch", which rolled
+   a similar logic on its own.
+
+ * When "git submodule add" clones a submodule repository, it can get
+   confused where to store the resulting submodule repository in the
+   superproject's .git/ directory when there is a symbolic link in the
+   path to the current directory.

+Git v1.7.11.6 Release Notes
+===========================
+
+Fixes since v1.7.11.5
+---------------------
+
+ * "ciabot" script (in contrib/) has been updated with extensive
+   documentation.
+
+ * "git foo" errored out with "Not a directory" when the user had a
+   non-directory on $PATH, and worse yet it masked an alias "foo" from
+   running.
+
+ * When the user exports a non-default IFS without HT, scripts that
+   rely on being able to parse "ls-files -s | while read a b c..."
+   started to fail.  Protect them from such a misconfiguration.
+
+ * When the user gives an argument that can be taken as both a
+   revision name and a pathname without disambiguating with "--", we
+   used to give a help message "Use '--' to separate".  The message
+   has been clarified to show where that '--' goes on the command
+   line.
+
+ * Documentation for the configuration file format had a confusing
+   example.
+
+ * Older parts of the documentation described as if having a regular
+   file in .git/refs/ hierarchy were the only way to have branches and
+   tags, which is not true for quite some time.
+
+ * It was generally understood that "--long-option"s to many of our
+   subcommands can be abbreviated to the unique prefix, but it was not
+   easy to find it described for new readers of the documentation set.
+
+ * The "--topo-order", "--date-order" (and the lack of either means
+   the default order) options to "rev-list" and "log" family of
+   commands were poorly described in the documentation.
+
+ * "git commit --amend" let the user edit the log message and then
+   died when the human-readable committer name was given
+   insufficiently by getpwent(3).
+
+ * The exit status code from "git config" was way overspecified while
+   being incorrect.  The implementation has been updated to give the
+   documented status for a case that was documented, and introduce a
+   new code for "all other errors".
+
+ * The output from "git diff -B" for a file that ends with an
+   incomplete line did not put "\ No newline..." on a line of its own.
+
+ * "git diff" had a confusion between taking data from a path in the
+   working tree and taking data from an object that happens to have
+   name 0{40} recorded in a tree.
+
+ * The "--rebase" option to "git pull" can be abbreviated to "-r",
+   but we didn't document it.
+
+ * When "git push" triggered the automatic gc on the receiving end, a
+   message from "git prune" that said it was removing cruft leaked to
+   the standard output, breaking the communication protocol.
+
+ * The reflog entries left by "git rebase" and "git rebase -i" were
+   inconsistent (the interactive one gave an abbreviated object name).
+
+ * "git send-email" did not unquote encoded words that appear on the
+   header correctly, and lost "_" from strings.
+
+ * "git stash apply/pop" did not trigger "rerere" upon conflicts
+   unlike other mergy operations.
+
+ * "git submodule <cmd> path" did not error out when the path to the
+   submodule was misspelt.
+
+ * "git submodule update -f" did not update paths in the working tree
+   that has local changes.
+   (merge 01d4721 sz/submodule-force-update later to maint).
+
+ * "gitweb" when used with PATH_INFO failed to notice directories with
+   SP (and other characters that need URL-style quoting) in them.
+
+ * Fallback 'getpass' implementation made unportable use of stdio API.
+
+ * A utility shell function test_seq has been added as a replacement
+   for the 'seq' utility found on some platforms.

+Git v1.7.11.7 Release Notes
+===========================

+---------------------
+
+ * The synopsis said "checkout [-B branch]" to make it clear the
+   branch name is a parameter to the option, but the heading for the
+   option description was "-B::", not "-B branch::", making the
+   documentation misleading.
+
+ * Git ships with a fall-back regexp implementation for platforms with
+   buggy regexp library, but it was easy for people to keep using their
+   platform regexp.  A new test has been added to check this.
+
+ * "git apply -p0" did not parse pathnames on "diff --git" line
+   correctly.  This caused patches that had pathnames in no other
+   places to be mistakenly rejected (most notably, binary patch that
+   does not rename nor change mode).  Textual patches, renames or mode
+   changes have preimage and postimage pathnames in different places
+   in a form that can be parsed unambiguously and did not suffer from
+   this problem.
+
+ * After "gitk" showed the contents of a tag, neither "Reread
+   references" nor "Reload" did not update what is shown as the
+   contents of it, when the user overwrote the tag with "git tag -f".
+
+ * "git for-each-ref" did not currectly support more than one --sort
+   option.
+
+ * "git log .." errored out saying it is both rev range and a path
+   when there is no disambiguating "--" is on the command line.
+   Update the command line parser to interpret ".." as a path in such
+   a case.
+
+ * Pushing to smart HTTP server with recent Git fails without having
+   the username in the URL to force authentication, if the server is
+   configured to allow GET anonymously, while requiring authentication
+   for POST.
+
+ * "git show --format='%ci'" did not give timestamp correctly for
+   commits created without human readable name on "committer" line.
+   (merge e27ddb6 jc/maint-ident-missing-human-name later to maint).
+
+ * "git show --quiet" ought to be a synonym for "git show -s", but

+Git v1.7.11 Release Notes
+=========================
+
+Updates since v1.7.10
+---------------------
+
+UI, Workflows & Features
+
+ * A new mode for push, "simple", which is a cross between "current"
+   and "upstream", has been introduced. "git push" without any refspec
+   will push the current branch out to the same name at the remote
+   repository only when it is set to track the branch with the same
+   name over there.  The plan is to make this mode the new default
+   value when push.default is not configured.
+
+ * A couple of commands learned the "--column" option to produce
+   columnar output.
+
+ * A third-party tool "git subtree" is distributed in contrib/
+
+ * A remote helper that acts as a proxy and caches ssl session for the
+   https:// transport is added to the contrib/ area.
+
+ * Error messages given when @{u} is used for a branch without its
+   upstream configured have been clarified.
+
+ * Even with the "-q"uiet option, "checkout" used to report setting up
+   tracking.  Also "branch" learned the "-q"uiet option to squelch
+   informational message.
+
+ * Your build platform may support hardlinks but you may prefer not to
+   use them, e.g. when installing to DESTDIR to make a tarball and
+   untarring on a filesystem that has poor support for hardlinks.
+   There is a Makefile option NO_INSTALL_HARDLINKS for you.
+
+ * The smart-http backend used to always override GIT_COMMITTER_*
+   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
+   now preserved when set.
+
+ * "git am" learned the "--include" option, which is an opposite of
+   existing the "--exclude" option.
+
+ * When "git am -3" needs to fall back to an application of the patch
+   to a synthesized preimage followed by a 3-way merge, the paths that
+   needed such treatment are now reported to the end user, so that the
+   result in them can be eyeballed with extra care.
+
+ * The output from "diff/log --stat" used to always allocate 4 columns
+   to show the number of modified lines, but not anymore.
+
+ * "git difftool" learned the "--dir-diff" option to spawn external
+   diff tools that can compare two directory hierarchies at a time
+   after populating two temporary directories, instead of running an
+   instance of the external tool once per a file pair.
+
+ * The "fmt-merge-msg" command learned to list the primary contributors
+   involved in the side topic you are merging in a comment in the merge
+   commit template.
+
+ * "git rebase" learned to optionally keep commits that do not
+   introduce any change in the original history.
+
+ * "git push --recurse-submodules" learned to optionally look into the
+   histories of submodules bound to the superproject and push them
+   out.
+
+ * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
+   based on the commit date.
+
+ * "gitweb" learned to highlight the patch it outputs even more.
+
+Foreign Interface
+
+ * "git svn" used to die with unwanted SIGPIPE when talking with an HTTP
+   server that uses keep-alive.
+
+ * "git svn" learned to use platform specific authentication
+   providers, e.g. gnome-keyring, kwallet, etc.
+
+ * "git p4" has been moved out of the contrib/ area and has seen more
+   work on importing labels as tags from (and exporting tags as labels
+   to) p4.
+
+Performance and Internal Implementation (please report possible regressions)
+
+ * Bash completion script (in contrib/) have been cleaned up to make
+   future work on it simpler.
+
+ * An experimental "version 4" format of the index file has been
+   introduced to reduce on-disk footprint and I/O overhead.
+
+ * "git archive" learned to produce its output without reading the
+   blob object it writes out in memory in its entirety.
+
+ * "git index-pack" that runs when fetching or pushing objects to
+   complete the packfile on the receiving end learned to use multiple
+   threads to do its job when available.
+
+ * The code to compute hash values for lines used by the internal diff
+   engine was optimized on little-endian machines, using the same
+   trick the kernel folks came up with.
+
+ * "git apply" had some memory leaks plugged.
+
+ * Setting up a revision traversal with many starting points was
+   inefficient as these were placed in a date-order priority queue
+   one-by-one.  Now they are collected in the queue unordered first,
+   and sorted immediately before getting used.
+
+ * More lower-level commands learned to use the streaming API to read
+   from the object store without keeping everything in core.
+
+ * The weighting parameters to suggestion command name typo have been
+   tweaked, so that "git tags" will suggest "tag?" and not "stage?".
+
+ * Because "sh" on the user's PATH may be utterly broken on some
+   systems, run-command API now uses SHELL_PATH, not /bin/sh, when
+   spawning an external command (not applicable to Windows port).
+
+ * The API to iterate over the refs/ hierarchy has been tweaked to
+   allow walking only a subset of it more efficiently.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.10
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * "git submodule init" used to report "registered for path ..."
+   even for submodules that were registered earlier.
+   (cherry-pick c1c259e jl/submodule-report-new-path-once later to maint).
+
+ * "git diff --stat" used to fully count a binary file with modified
+   execution bits whose contents is unmodified, which was not quite
+   right.

+
+ * "git commit --amend" let the user edit the log message and then

+ * Pushing to smart HTTP server with recent Git fails without having
+   the username in the URL to force authentication, if the server is
+   configured to allow GET anonymously, while requiring authentication
+   for POST.
+
+ * The reflog entries left by "git rebase" and "git rebase -i" were
+   inconsistent (the interactive one gave an abbreviated object name).
+
+ * When "git push" triggered the automatic gc on the receiving end, a
+   message from "git prune" that said it was removing cruft leaked to
+   the standard output, breaking the communication protocol.
+
+ * "git show --quiet" ought to be a synonym for "git show -s", but
+   wasn't.
+
+ * "git show --format='%ci'" did not give timestamp correctly for
+   commits created without human readable name on "committer" line.
+
+ * "git send-email" did not unquote encoded words that appear on the
+   header correctly, and lost "_" from strings.
+
+ * The interactive prompt "git send-email" gives was error prone. It
+   asked "What e-mail address do you want to use?" with the address it
+   guessed (correctly) the user would want to use in its prompt,
+   tempting the user to say "y". But the response was taken as "No,
+   please use 'y' as the e-mail address instead", which is most
+   certainly not what the user meant.
+
+ * "gitweb" when used with PATH_INFO failed to notice directories with
+   SP (and other characters that need URL-style quoting) in them.
+
+ * When the user gives an argument that can be taken as both a
+   revision name and a pathname without disambiguating with "--", we
+   used to give a help message "Use '--' to separate".  The message
+   has been clarified to show where that '--' goes on the command
+   line.
+
+ * When the user exports a non-default IFS without HT, scripts that
+   rely on being able to parse "ls-files -s | while read a b c..."
+   started to fail.  Protect them from such a misconfiguration.
+
+ * The attribute system may be asked for a path that itself or its
+   leading directories no longer exists in the working tree, and it is
+   fine if we cannot open .gitattribute file in such a case.  Failure
+   to open per-directory .gitattributes with error status other than
+   ENOENT and ENOTDIR should be diagnosed, but it wasn't.
+
+ * After "gitk" showed the contents of a tag, neither "Reread
+   references" nor "Reload" did not update what is shown as the
+   contents of it, when the user overwrote the tag with "git tag -f".
+
+ * "ciabot" script (in contrib/) has been updated with extensive
+   documentation.
+
+ * "git-jump" script (in contrib/) did not work well when
+   diff.noprefix or diff.mnemonicprefix is in effect.
+
+ * Older parts of the documentation described as if having a regular
+   file in .git/refs/ hierarchy were the only way to have branches and
+   tags, which is not true for quite some time.
+
+ * A utility shell function test_seq has been added as a replacement
+   for the 'seq' utility found on some platforms.
+
+ * Compatibility wrapper to learn the maximum number of file
+   descriptors we can open around sysconf(_SC_OPEN_MAX) and
+   getrlimit(RLIMIT_NO_FILE) has been introduced for portability.
+
+ * We used curl_easy_strerror() without checking version of cURL,
+   breaking the build for versions before curl 7.12.0.
+
+ * Code to work around MacOS X UTF-8 gotcha has been cleaned up.
+
+ * Fallback 'getpass' implementation made unportable use of stdio API.
+
+ * The "--rebase" option to "git pull" can be abbreviated to "-r",
+   but we didn't document it.
+
+ * It was generally understood that "--long-option"s to many of our
+   subcommands can be abbreviated to the unique prefix, but it was not
+   easy to find it described for new readers of the documentation set.
+
+ * The synopsis said "checkout [-B branch]" to make it clear the
+   branch name is a parameter to the option, but the heading for the
+   option description was "-B::", not "-B branch::", making the
+   documentation misleading.
+
+Also contains numerous documentation updates.

+Git 1.7.12.2 Release Notes
+==========================
+
+Fixes since v1.7.12.1
+---------------------
+
+ * When "git am" is fed an input that has multiple "Content-type: ..."
+   header, it did not grok charset= attribute correctly.
+
+ * Even during a conflicted merge, "git blame $path" always meant to
+   blame uncommitted changes to the "working tree" version; make it
+   more useful by showing cleanly merged parts as coming from the other
+   branch that is being merged.
+
+ * "git blame MAKEFILE" run in a history that has "Makefile" but not
+   "MAKEFILE" should say "No such file MAKEFILE in HEAD", but got
+   confused on a case insensitive filesystem and failed to do so.
+
+ * "git fetch --all", when passed "--no-tags", did not honor the
+   "--no-tags" option while fetching from individual remotes (the same
+   issue existed with "--tags", but combination "--all --tags" makes
+   much less sense than "--all --no-tags").
+
+ * "git log/diff/format-patch --stat" showed the "N line(s) added"
+   comment in user's locale and caused careless submitters to send
+   patches with such a line in them to projects whose project language
+   is not their language, mildly irritating others. Localization to
+   the line has been disabled for now.
+
+ * "git log --all-match --grep=A --grep=B" ought to show commits that
+   mention both A and B, but when these three options are used with
+   --author or --committer, it showed commits that mention either A or
+   B (or both) instead.
+
+ * The subcommand to remove the definition of a remote in "git remote"
+   was named "rm" even though all other subcommands were spelled out.
+   Introduce "git remote remove" to remove confusion, and keep "rm" as
+   a backward compatible synonym.
+
+Also contains a handful of documentation updates.

+Git 1.7.12.3 Release Notes
+==========================
+
+Fixes since v1.7.12.2
+---------------------
+
+ * "git am" mishandled a patch attached as application/octet-stream
+   (e.g. not text/*); Content-Transfer-Encoding (e.g. base64) was not
+   honored correctly.
+
+ * It was unclear in the documentation for "git blame" that it is
+   unnecessary for users to use the "--follow" option.
+
+ * A repository created with "git clone --single" had its fetch
+   refspecs set up just like a clone without "--single", leading the
+   subsequent "git fetch" to slurp all the other branches, defeating
+   the whole point of specifying "only this branch".
+
+ * "git fetch" over http had an old workaround for an unlikely server
+   misconfiguration; it turns out that this hurts debuggability of the
+   configuration in general, and has been reverted.
+
+ * "git fetch" over http advertised that it supports "deflate", which
+   is much less common, and did not advertise the more common "gzip" on
+   its Accept-Encoding header.
+
+ * "git receive-pack" (the counterpart to "git push") did not give
+   progress output while processing objects it received to the puser
+   when run over the smart-http protocol.
+
+ * "git status" honored the ignore=dirty settings in .gitmodules but
+   "git commit" didn't.
+
+Also contains a handful of documentation updates.

+
+ * It was possible to give specific paths for "asciidoc" and other
+   tools in the documentation toolchain, but not for "xmlto".
+
+ * "gitweb" did not give the correct committer timezone in its feed
+   output due to a typo.
+
+ * The "-Xours" (and similarly -Xtheirs) backend option to "git
+   merge -s recursive" was ignored for binary files.  Now it is
+   honored.
+
+ * The "binary" synthetic attribute made "diff" to treat the path as
+   binary, but not "merge".
+
+Also contains many documentation updates.

+Git v1.7.12 Release Notes
+=========================
+
+Updates since v1.7.11
+---------------------
+
+UI, Workflows & Features
+
+ * Git can be told to normalize pathnames it read from readdir(3) and
+   all arguments it got from the command line into precomposed UTF-8
+   (assuming that they come as decomposed UTF-8), in order to work
+   around issues on Mac OS.
+
+   I think there still are other places that need conversion
+   (e.g. paths that are read from stdin for some commands), but this
+   should be a good first step in the right direction.
+
+ * Per-user $HOME/.gitconfig file can optionally be stored in
+   $HOME/.config/git/config instead, which is in line with XDG.
+
+ * The value of core.attributesfile and core.excludesfile default to
+   $HOME/.config/git/attributes and $HOME/.config/git/ignore respectively
+   when these files exist.
+
+ * Logic to disambiguate abbreviated object names have been taught to
+   take advantage of object types that are expected in the context,
+   e.g. XXXXXX in the "git describe" output v1.2.3-gXXXXXX must be a
+   commit object, not a blob nor a tree.  This will help us prolong
+   the lifetime of abbreviated object names.
+
+ * "git apply" learned to wiggle the base version and perform three-way
+   merge when a patch does not exactly apply to the version you have.
+
+ * Scripted Porcelain writers now have access to the credential API via
+   the "git credential" plumbing command.
+
+ * "git help" used to always default to "man" format even on platforms
+   where "man" viewer is not widely available.
+
+ * "git clone --local $path" started its life as an experiment to
+   optionally use link/copy when cloning a repository on the disk, but
+   we didn't deprecate it after we made the option a no-op to always
+   use the optimization.  The command learned "--no-local" option to
+   turn this off, as a more explicit alternative over use of file://
+   URL.
+
+ * "git fetch" and friends used to say "remote side hung up
+   unexpectedly" when they failed to get response they expect from the
+   other side, but one common reason why they don't get expected
+   response is that the remote repository does not exist or cannot be
+   read. The error message in this case was updated to give better
+   hints to the user.
+
+ * "git help -w $cmd" can show HTML version of documentation for
+   "git-$cmd" by setting help.htmlpath to somewhere other than the
+   default location where the build procedure installs them locally;
+   the variable can even point at a http:// URL.
+
+ * "git rebase [-i] --root $tip" can now be used to rewrite all the
+   history leading to "$tip" down to the root commit.
+
+ * "git rebase -i" learned "-x <cmd>" to insert "exec <cmd>" after
+   each commit in the resulting history.
+
+ * "git status" gives finer classification to various states of paths
+   in conflicted state and offer advice messages in its output.
+
+ * "git submodule" learned to deal with nested submodule structure
+   where a module is contained within a module whose origin is
+   specified as a relative URL to its superproject's origin.
+
+ * A rather heavy-ish "git completion" script has been split to create
+   a separate "git prompting" script, to help lazy-autoloading of the
+   completion part while making prompting part always available.
+
+ * "gitweb" pays attention to various forms of credits that are
+   similar to "Signed-off-by:" lines in the commit objects and
+   highlights them accordingly.
+
+
+Foreign Interface
+
+ * "mediawiki" remote helper (in contrib/) learned to handle file
+   attachments.
+
+ * "git p4" now uses "Jobs:" and "p4 move" when appropriate.
+
+ * vcs-svn has been updated to clean-up compilation, lift 32-bit
+   limitations, etc.
+
+
+Performance, Internal Implementation, etc. (please report possible regressions)
+
+ * Some tests showed false failures caused by a bug in ecryptofs.
+
+ * We no longer use AsciiDoc7 syntax in our documentation and favor a
+   more modern style.
+
+ * "git am --rebasing" codepath was taught to grab authorship, log
+   message and the patch text directly out of existing commits.  This
+   will help rebasing commits that have confusing "diff" output in
+   their log messages.
+
+ * "git index-pack" and "git pack-objects" use streaming API to read
+   from the object store to avoid having to hold a large blob object
+   in-core while they are doing their thing.
+
+ * Code to match paths with exclude patterns learned to avoid calling
+   fnmatch() by comparing fixed leading substring literally when
+   possible.
+
+ * "git log -n 1 -- rarely-touched-path" was spending unnecessary
+   cycles after showing the first change to find the next one, only to
+   discard it.
+
+ * "git svn" got a large-looking code reorganization at the last
+   minute before the code freeze.
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.11
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.11 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * "git submodule add" was confused when the superproject did not have
+   its repository in its usual place in the working tree and GIT_DIR
+   and GIT_WORK_TREE was used to access it.
+
+ * "git commit --amend" let the user edit the log message and then died
+   when the human-readable committer name was given insufficiently by
+   getpwent(3).

+==========================
+
+Fixes since v1.7.2
+------------------
+
+ * "git instaweb" wasn't useful when your Apache was installed under a

+
+ * Similarly, "git web--browse" (invoked by "git help -w") learned that
+   chrome browser is sometimes called google-chrome.
+
+ * An overlong line after ".gitdir: " in a git file caused out of bounds

+
+ * "git config --path conf.var" to attempt to expand a variable conf.var
+   that uses "~/" short-hand segfaulted when $HOME environment variable
+   was not set.
+
+ * Documentation on Cygwin failed to build.
+
+ * The error message from "git pull blarg" when 'blarg' is an unknown

+
+ * When people try insane things such as delta-compressing 4GiB files, we

+ * "git fetch --tags" did not fetch tags when remote.<nick>.tagopt was set

+

+
+ * "git gc" incorrectly pruned a rerere record that was created long

+
+ * "git log --follow -M -p" was seriously broken in 1.7.2, reporting

+
+ * Running "git log" with an incorrect option started pager nevertheless,
+   forcing the user to dismiss it.
+
+ * "git rebase" did not work well when the user has diff.renames
+   configuration variable set.
+
+ * An earlier (and rather old) fix to "git rebase" against a rebased
+   upstream broke a more normal, non rebased upstream case rather badly,
+   attempting to re-apply patches that are already accepted upstream.
+
+ * "git submodule sync" forgot to update the superproject's config file

+
+ * "git pack-refs --all --prune" did not remove a directory that has

+Git v1.7.2 Release Notes
+========================
+
+Updates since v1.7.1
+--------------------
+
+ * core.eol configuration and text/eol attributes are the new way to control
+   the end of line conventions for files in the working tree.
+
+ * core.autocrlf has been made safer - it will now only handle line
+   endings for new files and files that are LF-only in the
+   repository. To normalize content that has been checked in with
+   CRLF, use the new eol/text attributes.
+
+ * The whitespace rules used in "git apply --whitespace" and "git diff"
+   gained a new member in the family (tab-in-indent) to help projects with
+   policy to indent only with spaces.
+
+ * When working from a subdirectory, by default, git does not look for its
+   metadirectory ".git" across filesystems, primarily to help people who
+   have invocations of git in their custom PS1 prompts, as being outside
+   of a git repository would look for ".git" all the way up to the root
+   directory, and NFS mounts are often slow.  DISCOVERY_ACROSS_FILESYSTEM
+   environment variable can be used to tell git not to stop at a
+   filesystem boundary.
+
+ * Usage help messages generated by parse-options library (i.e. most
+   of the Porcelain commands) are sent to the standard output now.
+
+ * ':/<string>' notation to look for a commit now takes regular expression
+   and it is not anchored at the beginning of the commit log message
+   anymore (this is a backward incompatible change).
+
+ * "git" wrapper learned "-c name=value" option to override configuration
+   variable from the command line.
+
+ * Improved portability for various platforms including older SunOS,
+   HP-UX 10/11, AIX, Tru64, etc. and platforms with Python 2.4.
+
+ * The message from "git am -3" has been improved when conflict
+   resolution ended up making the patch a no-op.
+
+ * "git blame" applies the textconv filter to the contents it works
+   on, when available.
+
+ * "git checkout --orphan newbranch" is similar to "-b newbranch" but
+   prepares to create a root commit that is not connected to any existing
+   commit.
+
+ * "git cherry-pick" learned to pick a range of commits
+   (e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git
+   revert"; these do not support the nicer sequencing control "rebase
+   [-i]" has, though.
+
+ * "git cherry-pick" and "git revert" learned --strategy option to specify
+   the merge strategy to be used when performing three-way merges.
+
+ * "git cvsserver" can be told to use pserver; its password file can be
+   stored outside the repository.
+
+ * The output from the textconv filter used by "git diff" can be cached to
+   speed up their reuse.
+
+ * "git diff --word-diff=<mode>" extends the existing "--color-words"
+   option, making it more useful in color-challenged environments.
+
+ * The regexp to detect function headers used by "git diff" for PHP has
+   been enhanced for visibility modifiers (public, protected, etc.) to
+   better support PHP5.
+
+ * "diff.noprefix" configuration variable can be used to implicitly
+   ask for "diff --no-prefix" behaviour.
+
+ * "git for-each-ref" learned "%(objectname:short)" that gives the object
+   name abbreviated.
+
+ * "git format-patch" learned --signature option and format.signature
+   configuration variable to customize the e-mail signature used in the
+   output.
+
+ * Various options to "git grep" (e.g. --count, --name-only) work better
+   with binary files.
+
+ * "git grep" learned "-Ovi" to open the files with hits in your editor.
+
+ * "git help -w" learned "chrome" and "chromium" browsers.
+
+ * "git log --decorate" shows commit decorations in various colours.
+
+ * "git log --follow <path>" follows across copies (it used to only follow
+   renames).  This may make the processing more expensive.
+
+ * "git log --pretty=format:<template>" specifier learned "% <something>"
+   magic that inserts a space only when %<something> expands to a
+   non-empty string; this is similar to "%+<something>" magic, but is
+   useful in a context to generate a single line output.
+
+ * "git notes prune" learned "-n" (dry-run) and "-v" options, similar to
+   what "git prune" has.
+
+ * "git patch-id" can be fed a mbox without getting confused by the
+   signature line in the format-patch output.
+
+ * "git remote" learned "set-branches" subcommand.
+
+ * "git rev-list A..B" learned --ancestry-path option to further limit
+   the result to the commits that are on the ancestry chain between A and
+   B (i.e. commits that are not descendants of A are excluded).
+
+ * "git show -5" is equivalent to "git show --do-walk 5"; this is similar
+   to the update to make "git show master..next" walk the history,
+   introduced in 1.6.4.
+
+ * "git status [-s] --ignored" can be used to list ignored paths.
+
+ * "git status -s -b" shows the current branch in the output.
+
+ * "git status" learned "--ignore-submodules" option.
+
+ * Various "gitweb" enhancements and clean-ups, including syntax
+   highlighting, "plackup" support for instaweb, .fcgi suffix to run
+   it as FastCGI script, etc.
+
+ * The test harness has been updated to produce TAP-friendly output.
+
+ * Many documentation improvement patches are also included.
+
+
+Fixes since v1.7.1
+------------------
+
+All of the fixes in v1.7.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * We didn't URL decode "file:///path/to/repo" correctly when path/to/repo
+   had percent-encoded characters (638794c, 9d2e942, ce83eda, 3c73a1d).
+
+ * "git clone" did not configure remote.origin.url correctly for bare
+   clones (df61c889).
+
+ * "git diff --graph" works better with "--color-words" and other options
+   (81fa024..4297c0a).
+
+ * "git diff" could show ambiguous abbreviation of blob object names on
+   its "index" line (3e5a188).
+
+ * "git reset --hard" started from a wrong directory and a working tree in
+   a nonstandard location is in use got confused (560fb6a1).
+
+ * "git read-tree -m A B" used to switch to branch B while retaining
+   local changes added an incorrect cache-tree information (b1f47514).

+Git v1.7.3.3 Release Notes
+==========================
+
+In addition to the usual fixes, this release also includes support for
+the new "add.ignoreErrors" name given to the existing "add.ignore-errors"
+configuration variable.
+
+The next version, Git 1.7.4, and future versions, will support both
+old and incorrect name and the new corrected name, but without this
+backport, users who want to use the new name "add.ignoreErrors" in
+their repositories cannot use older versions of Git.
+
+Fixes since v1.7.3.2
+--------------------
+
+ * "git apply" segfaulted when a bogus input is fed to it.
+
+ * Running "git cherry-pick --ff" on a root commit segfaulted.
+
+ * "diff", "blame" and friends incorrectly applied textconv filters to
+   symlinks.
+
+ * Highlighting of whitespace breakage in "diff" output was showing
+   incorrect amount of whitespaces when blank-at-eol is set and the line
+   consisted only of whitespaces and a TAB.
+
+ * "diff" was overly inefficient when trying to find the line to use for
+   the function header (i.e. equivalent to --show-c-function of GNU diff).
+
+ * "git imap-send" depends on libcrypto but our build rule relied on the
+   linker to implicitly link it via libssl, which was wrong.
+
+ * "git merge-file" can be called from within a subdirectory now.
+
+ * "git repack -f" expanded and recompressed non-delta objects in the
+   existing pack, which was wasteful.  Use new "-F" option if you really
+   want to (e.g. when changing the pack.compression level).
+
+ * "git rev-list --format="...%x00..." incorrectly chopped its output
+   at NUL.
+
+ * "git send-email" did not correctly remove duplicate mail addresses from
+   the Cc: header that appear on the To: header.
+
+ * The completion script (in contrib/completion) ignored lightweight tags
+   in __git_ps1().
+
+ * "git-blame" mode (in contrib/emacs) didn't say (require 'format-spec)
+   even though it depends on it; it didn't work with Emacs 22 or older
+   unless Gnus is used.
+
+ * "git-p4" (in contrib/) did not correctly handle deleted files.
+
+Other minor fixes and documentation updates are also included.

+Git v1.7.3.4 Release Notes
+==========================
+
+Fixes since v1.7.3.3
+--------------------
+
+ * Smart HTTP transport used to incorrectly retry redirected POST
+   request with GET request.
+
+ * "git apply" did not correctly handle patches that only change modes
+   if told to apply while stripping leading paths with -p option.
+
+ * "git apply" can deal with patches with timezone formatted with a
+   colon between the hours and minutes part (e.g. "-08:00" instead of
+   "-0800").
+
+ * "git checkout" removed an untracked file "foo" from the working
+   tree when switching to a branch that contains a tracked path
+   "foo/bar".  Prevent this, just like the case where the conflicting
+   path were "foo" (c752e7f..7980872d).
+
+ * "git cherry-pick" or "git revert" refused to work when a path that
+   would be modified by the operation was stat-dirty without a real
+   difference in the contents of the file.
+
+ * "git diff --check" reported an incorrect line number for added
+   blank lines at the end of file.
+
+ * "git imap-send" failed to build under NO_OPENSSL.
+
+ * Setting log.decorate configuration variable to "0" or "1" to mean
+   "false" or "true" did not work.
+
+ * "git push" over dumb HTTP protocol did not work against WebDAV
+   servers that did not terminate a collection name with a slash.
+
+ * "git tag -v" did not work with GPG signatures in rfc1991 mode.
+
+ * The post-receive-email sample hook was accidentally broken in 1.7.3.3
+   update.
+
+ * "gitweb" can sometimes be tricked into parrotting a filename argument
+   given in a request without properly quoting.
+
+Other minor fixes and documentation updates are also included.

+Git 1.7.3.5 Release Notes
+=========================
+
+ * The xfuncname pattern used by "git diff" and "git grep" to show the
+   last notable line in context were broken for python and ruby for a long
+   time.
+
+ * "git merge" into an unborn branch removed an untracked file "foo" from
+   the working tree when merged branch had "foo" (this fix was already in
+   1.7.3.3 but was omitted from the release notes by mistake).
+
+ * "git status -s" did not quote unprintable characters in paths as
+   documented.
+
+ * "git am --abort" used to always reset to the commit at the beginning of
+   the last "am" invocation that has stopped, losing any unrelated commits
+   that may have been made since then.  Now it refrains from doing so and
+   instead issues a warning.
+
+ * "git blame" incorrectly reused bogusly cached result of textconv
+   filter for files from the working tree.
+
+ * "git commit" used to abort after the user edited the log message
+   when the committer information was not correctly set up.  It now
+   aborts before starting the editor.
+
+ * "git commit --date=invalid" used to silently ignore the incorrectly
+   specified date; it is now diagnosed as an error.
+
+ * "git rebase --skip" to skip the last commit in a series used to fail
+   to run post-rewrite hook and to copy notes from old commits that have
+   successfully been rebased so far.  Now it do (backmerge ef88ad2).
+
+ * "gitweb" tried to show a wrong feed logo when none was specified.

+Git v1.7.3 Release Notes
+========================
+
+Updates since v1.7.2
+--------------------
+
+ * git-gui, now at version 0.13.0, got various updates and a new
+   maintainer, Pat Thoyts.
+
+ * Gitweb allows its configuration to change per each request; it used to
+   read the configuration once upon startup.
+
+ * When git finds a corrupt object, it now reports the file that contains
+   it.
+
+ * "git checkout -B <it>" is a shorter way to say "git branch -f <it>"
+   followed by "git checkout <it>".
+
+ * When "git checkout" or "git merge" refuse to proceed in order to
+   protect local modification to your working tree, they used to stop
+   after showing just one path that might be lost.  They now show all,
+   in a format that is easier to read.
+
+ * "git clean" learned "-e" ("--exclude") option.
+
+ * Hunk headers produced for C# files by "git diff" and friends show more
+   relevant context than before.
+
+ * diff.ignoresubmodules configuration variable can be used to squelch the
+   differences in submodules reported when running commands (e.g. "diff",
+   "status", etc.) at the superproject level.
+
+ * http.useragent configuration can be used to lie who you are to your
+   restrictive firewall.
+
+ * "git rebase --strategy <s>" learned "-X" option to pass extra options
+   that are understood by the chosen merge strategy.
+
+ * "git rebase -i" learned "exec" that you can insert into the insn sheet
+   to run a command between its steps.
+
+ * "git rebase" between branches that have many binary changes that do
+   not conflict should be faster.
+
+ * "git rebase -i" peeks into rebase.autosquash configuration and acts as
+   if you gave --autosquash from the command line.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.2
+------------------
+
+All of the fixes in v1.7.2.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git merge -s recursive" (which is the default) did not handle cases
+   where a directory becomes a file (or vice versa) very well.
+
+ * "git fetch" and friends were accidentally broken for url with "+" in
+   its path, e.g. "git://git.gnome.org/gtk+".
+
+ * "git fetch $url" (i.e. without refspecs) was broken for quite some
+   time, if the current branch happen to be tracking some remote.
+
+ * "git ls-tree dir dirgarbage", when "dir" was a directory,
+   incorrectly recursed into "dir".
+
+ * "git note remove" created unnecessary extra commit when named object
+   did not have any note to begin with.
+
+ * "git rebase" did not work well if you had diff.noprefix configured.
+
+ * "git -c foo=bar subcmd" did not work well for subcmd that is not
+   implemented as a built-in command.

+==========================
+
+Fixes since v1.7.4.1
+--------------------
+
+ * Many documentation updates to match "git cmd -h" output and the
+   git-cmd manual page.
+
+ * We used to keep one file descriptor open for each and every packfile
+   that we have a mmap window on it (read: "in use"), even when for very
+   tiny packfiles.  We now close the file descriptor early when the entire
+   packfile fits inside one mmap window.
+
+ * "git bisect visualize" tried to run "gitk" in windowing
+   environments even when "gitk" is not installed, resulting in a
+   strange error message.
+
+ * "git clone /no/such/path" did not fail correctly.
+
+ * "git commit" did not correctly error out when the user asked to use a
+   non existent file as the commit message template.
+
+ * "git diff --stat -B" ran on binary files counted the changes in lines,
+   which was nonsensical.
+
+ * "git diff -M" opportunistically detected copies, which was not
+   necessarily a good thing, especially when it is internally run by
+   recursive merge.
+
+ * "git difftool" didn't tell (g)vimdiff that the files it is reading are
+   to be opened read-only.
+
+ * "git merge" didn't pay attention to prepare-commit-msg hook, even
+   though if a merge is conflicted and manually resolved, the subsequent
+   "git commit" would have triggered the hook, which was inconsistent.
+
+ * "git patch-id" (and commands like "format-patch --ignore-in-upstream"
+   that use it as their internal logic) handled changes to files that end
+   with incomplete lines incorrectly.
+
+ * The official value to tell "git push" to push the current branch back
+   to update the upstream branch it forked from is now called "upstream".
+   The old name "tracking" is and will be supported.
+
+ * "git submodule update" used to honor the --merge/--rebase option (or
+   corresponding configuration variables) even for a newly cloned
+   subproject, which made no sense (so/submodule-no-update-first-time).
+
+ * gitweb's "highlight" interface mishandled tabs.
+
+ * gitweb didn't understand timezones with GMT offset that is not
+   multiple of a whole hour.
+
+ * gitweb had a few forward-incompatible syntactic constructs and
+   also used incorrect variable when showing the file mode in a diff.
+
+And other minor fixes and documentation updates.

+Git v1.7.4 Release Notes
+========================
+
+Updates since v1.7.3
+--------------------
+
+ * The documentation Makefile now assumes by default asciidoc 8 and
+   docbook-xsl >= 1.73. If you have older versions, you can set
+   ASCIIDOC7 and ASCIIDOC_ROFF, respectively.
+
+ * The option parsers of various commands that create new branches (or
+   rename existing ones to a new name) were too loose and users were
+   allowed to give a branch a name that begins with a dash by creative
+   abuse of their command line options, which only led to burning
+   themselves.  The name of a branch cannot begin with a dash now.
+
+ * System-wide fallback default attributes can be stored in
+   /etc/gitattributes; the core.attributesfile configuration variable can
+   be used to customize the path to this file.
+
+ * The thread structure generated by "git send-email" has changed
+   slightly.  Setting the cover letter of the latest series as a reply
+   to the cover letter of the previous series with --in-reply-to used
+   to make the new cover letter and all the patches replies to the
+   cover letter of the previous series; this has been changed to make
+   the patches in the new series replies to the new cover letter.
+
+ * The Bash completion script in contrib/ has been adjusted to be usable with
+   Bash 4 (options with '=value' didn't complete).  It has been also made
+   usable with zsh.
+
+ * Different pagers can be chosen depending on which subcommand is
+   being run under the pager, using the "pager.<subcommand>" variable.
+
+ * The hardcoded tab-width of 8 that is used in whitespace breakage checks is now
+   configurable via the attributes mechanism.
+
+ * Support of case insensitive filesystems (i.e. "core.ignorecase") has
+   been improved.  For example, the gitignore mechanism didn't pay attention
+   to case insensitivity.
+
+ * The <tree>:<path> syntax for naming a blob in a tree, and the :<path>
+   syntax for naming a blob in the index (e.g. "master:Makefile",
+   ":hello.c") have been extended.  You can start <path> with "./" to
+   implicitly have the (sub)directory you are in prefixed to the
+   lookup.  Similarly, ":../Makefile" from a subdirectory would mean
+   "the Makefile of the parent directory in the index".
+
+ * "git blame" learned the --show-email option to display the e-mail
+   addresses instead of the names of authors.
+
+ * "git commit" learned the --fixup and --squash options to help later invocation
+   of interactive rebase.
+
+ * Command line options to "git cvsimport" whose names are in capital
+   letters (-A, -M, -R and -S) can now be specified as the default in
+   the .git/config file by their longer names (cvsimport.authorsFile,
+   cvsimport.mergeRegex, cvsimport.trackRevisions, cvsimport.ignorePaths).
+
+ * "git daemon" can be built in the MinGW environment.
+
+ * "git daemon" can take more than one --listen option to listen to
+   multiple addresses.
+
+ * "git describe --exact-match" was optimized not to read commit
+   objects unnecessarily.
+
+ * "git diff" and "git grep" learned what functions and subroutines
+   in Fortran, Pascal and Perl look like.
+
+ * "git fetch" learned the "--recurse-submodules" option.
+
+ * "git mergetool" tells vim/gvim to show a three-way diff by default
+   (use vimdiff2/gvimdiff2 as the tool name for old behavior).
+
+ * "git log -G<pattern>" limits the output to commits whose change has
+   added or deleted lines that match the given pattern.
+
+ * "git read-tree" with no argument as a way to empty the index is
+   deprecated; we might want to remove it in the future.  Users can
+   use the new --empty option to be more explicit instead.
+
+ * "git repack -f" does not spend cycles to recompress objects in the
+   non-delta representation anymore (use -F if you really mean it
+   e.g. after you changed the core.compression variable setting).
+
+ * "git merge --log" used to limit the resulting merge log to 20
+   entries; this is now customizable by giving e.g. "--log=47".
+
+ * "git merge" may work better when all files were moved out of a
+   directory in one branch while a new file is created in place of that
+   directory in the other branch.
+
+ * "git merge" learned the "--abort" option, synonymous to
+   "git reset --merge" when a merge is in progress.
+
+ * "git notes" learned the "merge" subcommand to merge notes refs.
+   In addition to the default manual conflict resolution, there are
+   also several notes merge strategies for automatically resolving
+   notes merge conflicts.
+
+ * "git rebase --autosquash" can use SHA-1 object names to name the
+   commit which is to be fixed up (e.g. "fixup! e83c5163").
+
+ * The default "recursive" merge strategy learned the --rename-threshold
+   option to influence the rename detection, similar to the -M option
+   of "git diff".  From the "git merge" frontend, the "-X<strategy option>"
+   interface, e.g. "git merge -Xrename-threshold=50% ...", can be used
+   to trigger this.
+
+ * The "recursive" strategy also learned to ignore various whitespace
+   changes; the most notable is -Xignore-space-at-eol.
+
+ * "git send-email" learned "--to-cmd", similar to "--cc-cmd", to read
+   the recipient list from a command output.
+
+ * "git send-email" learned to read and use "To:" from its input files.
+
+ * you can extend "git shell", which is often used on boxes that allow
+   git-only login over ssh as login shell, with a custom set of
+   commands.
+
+ * The current branch name in "git status" output can be colored differently
+   from the generic header color by setting the "color.status.branch" variable.
+
+ * "git submodule sync" updates metainformation for all submodules,
+   not just the ones that have been checked out.
+
+ * gitweb can use a custom 'highlight' command with its configuration file.
+
+ * other gitweb updates.
+
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.3
+------------------
+
+All of the fixes in the v1.7.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git log --author=me --author=her" did not find commits written by
+   me or by her; instead it looked for commits written by me and by
+   her, which is impossible.
+
+ * "git push --progress" shows progress indicators now.
+
+ * "git rebase -i" showed a confusing error message when given a
+   branch name that does not exist.
+
+ * "git repack" places its temporary packs under $GIT_OBJECT_DIRECTORY/pack
+   instead of $GIT_OBJECT_DIRECTORY/ to avoid cross directory renames.
+
+ * "git submodule update --recursive --other-flags" passes flags down
+   to its subinvocations.

+Git v1.7.5.1 Release Notes
+==========================
+
+Fixes since v1.7.5
+------------------
+
+ * When an object "$tree:$path" does not exist, if $path does exist in the
+   subtree of $tree that corresponds to the subdirectory the user is in,
+   git now suggests using "$tree:./$path" in addition to the advice to use
+   the full path from the root of the working tree.
+
+ * The "--date=relative" output format used to say "X years, 12 months"
+   when it should have said "X+1 years".
+
+ * The smart-HTTP transfer was broken in 1.7.5 when the client needs
+   to issue a small POST (which uses content-length) and then a large
+   POST (which uses chunked) back to back.
+
+ * "git clean" used to fail on an empty directory that is not readable,
+   even though rmdir(2) could remove such a directory.  Now we attempt it
+   as the last resort.
+
+ * The "--dirstat" option of "diff" family of commands used to totally
+   ignore a change that only rearranged lines within a file.  Such a
+   change now counts as at least a minimum but non zero change.
+
+ * The "--dirstat" option of "diff" family of commands used to use the
+   pathname in the original, instead of the pathname in the result,
+   when renames are involved.
+
+ * "git pack-object" did not take core.bigfilethreashold into account
+   (unlike fast-import); now it does.
+
+ * "git reflog" ignored options like "--format=.." on the command line.
+
+ * "git stash apply" used to refuse to work if there was any change in
+   the working tree, even when the change did not overlap with the change
+   the stash recorded.
+
+ * "git stash apply @{99999}" was not diagnosed as an error, even when you
+   did not have that many stash entries.
+
+ * An error message from "git send-email" to diagnose a broken SMTP
+   connection configuration lacked a space between "hello=<smtp-domain>"
+   and "port=<smtp-server-port>".
+
+And other minor fixes and documentation updates.

+Git v1.7.5.2 Release Notes
+==========================
+
+The release notes to 1.7.5.1 forgot to mention:
+
+ * "git stash -p --no-keep-index" and "git stash --no-keep-index -p" now
+   mean the same thing.
+
+ * "git upload-pack" (hence "git push" over git native protocol) had a
+   subtle race condition that could lead to a deadlock.
+
+Fixes since v1.7.5.1
+--------------------
+
+ * "git add -p" did not work correctly when a hunk is split and then
+   one of them was given to the editor.
+
+ * "git add -u" did not resolve a conflict where our history deleted and
+   their history modified the same file, and the working tree resolved to
+   keep a file.
+
+ * "git cvsimport" did not know that CVSNT stores its password file in a
+   location different from the traditional CVS.
+
+ * "git diff-files" did not show the mode information from the working
+   tree side of an unmerged path correctly.
+
+ * "git diff -M --cached" used to use unmerged path as a possible rename
+   source candidate, which made no sense.
+
+ * The option name parser in "git fast-import" used prefix matches for
+   some options where it shouldn't, and accepted non-existent options,
+   e.g. "--relative-marksmith" or "--forceps".
+
+ * "git format-patch" did not quote RFC822 special characters in the
+   email address (e.g From: Junio C. Hamano <jch@example.com>, not
+   From: "Junio C. Hamano" <jch@example.com>).
+
+ * "git format-patch" when run with "--quiet" option used to produce a
+   nonsense result that consists of alternating empty output.
+
+ * In "git merge", per-branch branch.<name>.mergeoptions configuration
+   variables did not override the fallback default merge.<option>
+   configuration variables such as merge.ff, merge.log, etc.
+
+ * "git merge-one-file" did not honor GIT_WORK_TREE settings when
+   handling a "both sides added, differently" conflict.
+
+ * "git mergetool" did not handle conflicted submoudules gracefully.
+
+ * "git-p4" (in contrib) used a wrong base image while merge a file that
+   was added on both branches differently.
+
+ * "git rebase -i -p" failed to preserve the history when there is a
+   redundant merge created with the --no-ff option.
+
+And other minor fixes and documentation updates.

+Git v1.7.5.3 Release Notes
+==========================
+
+Fixes since v1.7.5.2
+--------------------
+
+ * The bash completion scripts should correctly work using zsh's bash
+   completion emulation layer now.
+
+ * Setting $(prefix) in config.mak did not affect where etc/gitconfig
+   file is read from, even though passing it from the command line of
+   $(MAKE) did.
+
+ * The logic to handle "&" (expand to UNIX username) in GECOS field
+   miscounted the length of the name it formatted.
+
+ * "git cherry-pick -s resolve" failed to cherry-pick a root commit.
+
+ * "git diff --word-diff" misbehaved when diff.suppress-blank-empty was
+   in effect.
+
+ * "git log --stdin path" with an input that has additional pathspec
+   used to corrupt memory.
+
+ * "git send-pack" (hence "git push") over smalt-HTTP protocol could
+   deadlock when the client side pack-object died early.
+
+ * Compressed tarball gitweb generates used to be made with the timestamp
+   of the tarball generation; this was bad because snapshot from the same
+   tree should result in a same tarball.
+
+And other minor fixes and documentation updates.

+Git v1.7.5.4 Release Notes
+==========================
+

+--------------------
+
+ * The single-key mode of "git add -p" was easily fooled into thinking

+   mistake.
+
+ * Setting a git command that uses custom configuration via "-c var=val"
+   as an alias caused a crash due to a realloc(3) failure.
+
+ * "git diff -C -C" used to disable the rename detection entirely when
+   there are too many copy candidate paths in the tree; now it falls
+   back to "-C" when doing so would keep the copy candidate paths
+   under the rename detection limit.
+
+ * "git rerere" did not diagnose a corrupt MERGE_RR file in some cases.
+
+And other minor fixes and documentation updates.

+Git v1.7.5 Release Notes
+========================
+
+Updates since v1.7.4
+--------------------
+
+ * Various MinGW portability fixes.
+
+ * Various git-p4 enhancements (in contrib).
+
+ * Various vcs-svn, git-svn and gitk enhancements and fixes.
+
+ * Various git-gui updates (0.14.0).
+
+ * Update to more modern HP-UX port.
+
+ * The codebase is getting prepared for i18n/l10n; no translated
+   strings nor translation mechanism in the code yet, but the strings
+   are being marked for l10n.
+
+ * The bash completion script can now complete symmetric difference
+   for "git diff" command, e.g. "git diff ...bra<TAB>".
+
+ * The default minimum length of abbreviated and unique object names
+   can now be configured by setting the core.abbrev configuration
+   variable.
+
+ * "git apply -v" reports offset lines when the patch does not apply at
+   the exact location recorded in the diff output.
+
+ * "git config" used to be also known as "git repo-config", but the old
+   name is now officially deprecated.
+
+ * "git checkout --detach <commit>" is a more user friendly synonym for
+   "git checkout <commit>^0".
+
+ * "git checkout" performed on detached HEAD gives a warning and
+   advice when the commit being left behind will become unreachable from
+   any branch or tag.
+
+ * "git cherry-pick" and "git revert" can be told to use a custom merge
+   strategy, similar to "git rebase".
+
+ * "git cherry-pick" remembers which commit failed to apply when it is
+   stopped by conflicts, making it unnecessary to use "commit -c $commit"
+   to conclude it.
+
+ * "git cvsimport" bails out immediately when the cvs server cannot be
+   reached, without spewing unnecessary error messages that complain about
+   the server response it never got.
+
+ * "git fetch" vs "git upload-pack" transfer learned 'no-done'
+   protocol extension to save one round-trip after the content
+   negotiation is done. This saves one HTTP RPC, reducing the overall
+   latency for a trivial fetch.
+
+ * "git fetch" can be told to recursively fetch submodules on-demand.
+
+ * "git grep -f <filename>" learned to treat "-" as "read from the
+   standard input stream".
+
+ * "git grep --no-index" did not honor pathspecs correctly, returning
+   paths outside the specified area.
+
+ * "git init" learned the --separate-git-dir option to allow the git
+   directory for a new repository created elsewhere and linked via the
+   gitdir mechanism. This is primarily to help submodule support later
+   to switch between a branch of superproject that has the submodule
+   and another that does not.
+
+ * "git log" type commands now understand globbing pathspecs.  You
+   can say "git log -- '*.txt'" for example.
+
+ * "git log" family of commands learned --cherry and --cherry-mark
+   options that can be used to view two diverged branches while omitting
+   or highlighting equivalent changes that appear on both sides of a
+   symmetric difference (e.g. "log --cherry A...B").
+
+ * A lazy "git merge" that didn't say what to merge used to be an error.
+   When run on a branch that has an upstream defined, however, the command
+   now merges from the configured upstream.
+
+ * "git mergetool" learned how to drive "beyond compare 3" as well.
+
+ * "git rerere forget" without pathspec used to forget all the saved
+   conflicts that relate to the current merge; it now requires you to
+   give it pathspecs.
+
+ * "git rev-list --objects $revs -- $pathspec" now limits the objects listed
+   in its output properly with the pathspec, in preparation for narrow
+   clones.
+
+ * "git push" with no parameters gives better advice messages when
+   "tracking" is used as the push.default semantics or there is no remote
+   configured yet.
+
+ * A possible value to the "push.default" configuration variable,
+   'tracking', gained a synonym that more naturally describes what it
+   does, 'upstream'.
+
+ * "git rerere" learned a new subcommand "remaining" that is similar to
+   "status" and lists the paths that had conflicts which are known to
+   rerere, but excludes the paths that have already been marked as
+   resolved in the index from its output.  "git mergetool" has been
+   updated to use this facility.
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.4
+------------------
+
+All of the fixes in the v1.7.4.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git fetch" from a client that is mostly following the remote
+   needlessly told all of its refs to the server for both sides to
+   compute the set of objects that need to be transferred efficiently,
+   instead of stopping when the server heard enough. In a project with
+   many tags, this turns out to be extremely wasteful, especially over
+   the smart HTTP transport (sp/maint-{upload,fetch}-pack-stop-early~1).
+
+ * "git fetch" run from a repository that uses the same repository as
+   its alternate object store as the repository it is fetching from
+   did not tell the server that it already has access to objects
+   reachable from the refs in their common alternate object store,
+   causing it to fetch unnecessary objects (jc/maint-fetch-alt).
+
+ * "git remote add --mirror" created a configuration that is suitable for
+   doing both a mirror fetch and a mirror push at the same time, which
+   made little sense.  We now warn and require the command line to specify
+   either --mirror=fetch or --mirror=push.

+Git v1.7.6.1 Release Notes
+==========================
+
+Fixes since v1.7.6
+------------------
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+   functions can compress or uncompress more than 4GB data in one call on
+   platforms with 64-bit long, which has been corrected.
+
+ * "git unexecutable" reported that "unexecutable" was not found, even
+   though the actual error was that "unexecutable" was found but did
+   not have a proper she-bang line to be executed.
+
+ * Error exits from $PAGER were silently ignored.
+
+ * "git checkout -b <branch>" was confused when attempting to create a
+   branch whose name ends with "-g" followed by hexadecimal digits,
+   and refused to work.
+
+ * "git checkout -b <branch>" sometimes wrote a bogus reflog entry,
+   causing later "git checkout -" to fail.
+
+ * "git diff --cc" learned to correctly ignore binary files.
+
+ * "git diff -c/--cc" mishandled a deletion that resolves a conflict, and
+   looked in the working tree instead.
+
+ * "git fast-export" forgot to quote pathnames with unsafe characters
+   in its output.
+
+ * "git fetch" over smart-http transport used to abort when the
+   repository was updated between the initial connection and the
+   subsequent object transfer.
+
+ * "git fetch" did not recurse into submodules in subdirectories.
+
+ * "git ls-tree" did not error out when asked to show a corrupt tree.
+
+ * "git pull" without any argument left an extra whitespace after the
+   command name in its reflog.
+
+ * "git push --quiet" was not really quiet.
+
+ * "git rebase -i -p" incorrectly dropped commits from side branches.
+
+ * "git reset [<commit>] paths..." did not reset the index entry correctly
+   for unmerged paths.
+
+ * "git submodule add" did not allow a relative repository path when
+   the superproject did not have any default remote url.
+
+ * "git submodule foreach" failed to correctly give the standard input to
+   the user-supplied command it invoked.
+
+ * submodules that the user has never showed interest in by running
+   "git submodule init" was incorrectly marked as interesting by "git
+   submodule sync".
+
+ * "git submodule update --quiet" was not really quiet.
+
+  * "git tag -l <glob>..." did not take multiple glob patterns from the
+   command line.

+Git v1.7.6 Release Notes
+========================
+
+Updates since v1.7.5
+--------------------
+
+ * Various git-svn updates.
+
+ * Updates the way content tags are handled in gitweb.  Also adds
+   a UI to choose common timezone for displaying the dates.
+
+ * Similar to branch names, tagnames that begin with "-" are now
+   disallowed.
+
+ * Clean-up of the C part of i18n (but not l10n---please wait)
+   continues.
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Pushing and pulling from a repository with large number of refs that
+   point to identical commits are optimized by not listing the same commit
+   during the common ancestor negotiation exchange with the other side.
+
+ * Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
+   using "git add" will send the contents straight to a packfile without
+   having to hold it and its compressed representation both at the same
+   time in memory.
+
+ * Processes spawned by "[alias] <name> = !process" in the configuration
+   can inspect GIT_PREFIX environment variable to learn where in the
+   working tree the original command was invoked.
+
+ * A magic pathspec ":/" tells a command that limits its operation to
+   the current directory when ran from a subdirectory to work on the
+   entire working tree. In general, ":/path/to/file" would be relative
+   to the root of the working tree hierarchy.
+
+   After "git reset --hard; edit Makefile; cd t/", "git add -u" would
+   be a no-op, but "git add -u :/" would add the updated contents of
+   the Makefile at the top level. If you want to name a path in the
+   current subdirectory whose unusual name begins with ":/", you can
+   name it by "./:/that/path" or by "\:/that/path".
+
+ * "git blame" learned "--abbrev[=<n>]" option to control the minimum
+   number of hexdigits shown for commit object names.
+
+ * "git blame" learned "--line-porcelain" that is less efficient but is
+   easier to parse.
+
+ * Aborting "git commit --interactive" discards updates to the index
+   made during the interactive session.
+
+ * "git commit" learned a "--patch" option to directly jump to the
+   per-hunk selection UI of the interactive mode.
+
+ * "git diff" and its family of commands learned --dirstat=0 to show
+   directories that contribute less than 0.1% of changes.
+
+ * "git diff" and its family of commands learned --dirstat=lines mode to
+   assess damage to the directory based on number of lines in the patch
+   output, not based on the similarity numbers.
+
+ * "git format-patch" learned "--quiet" option to suppress the output of
+   the names of generated files.
+
+ * "git format-patch" quotes people's names when it has RFC822 special
+   characters in it, e.g. "Junio C. Hamano" <jch@example.com>.  Earlier
+   it was up to the user to do this when using its output.
+
+ * "git format-patch" can take an empty --subject-prefix now.
+
+ * "git grep" learned the "-P" option to take pcre regular expressions.
+
+ * "git log" and friends learned a new "--notes" option to replace the
+   "--show-notes" option.  Unlike "--show-notes", "--notes=<ref>" does
+   not imply showing the default notes.
+
+ * They also learned a log.abbrevCommit configuration variable to augment
+   the --abbrev-commit command line option.
+
+ * "git ls-remote" learned "--exit-code" option to consider it a
+   different kind of error when no remote ref to be shown.
+
+ * "git merge" learned "-" as a short-hand for "the previous branch", just
+   like the way "git checkout -" works.
+
+ * "git merge" uses "merge.ff" configuration variable to decide to always
+   create a merge commit (i.e. --no-ff, aka merge.ff=no), refuse to create
+   a merge commit (i.e. --ff-only, aka merge.ff=only). Setting merge.ff=yes
+   (or not setting it at all) restores the default behaviour of allowing
+   fast-forward to happen when possible.
+
+ * p4-import (from contrib) learned a new option --preserve-user.
+
+ * "git read-tree -m" learned "--dry-run" option that reports if a merge
+   would fail without touching the index nor the working tree.
+
+ * "git rebase" that does not specify on top of which branch to rebase
+   the current branch now uses @{upstream} of the current branch.
+
+ * "git rebase" finished either normally or with --abort did not
+   update the reflog for HEAD to record the event to come back to
+   where it started from.
+
+ * "git remote add -t only-this-branch --mirror=fetch" is now allowed. Earlier
+   a fetch-mode mirror meant mirror everything, but now it only means refs are
+   not renamed.
+
+ * "git rev-list --count" used with "--cherry-mark" counts the cherry-picked
+   commits separately, producing more a useful output.
+
+ * "git submodule update" learned "--force" option to get rid of local
+   changes in submodules and replace them with the up-to-date version.
+
+ * "git status" and friends ignore .gitmodules file while the file is
+   still in a conflicted state during a merge, to avoid using information
+   that is not final and possibly corrupt with conflict markers.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.5
+------------------
+
+Unless otherwise noted, all the fixes in 1.7.5.X maintenance track are
+included in this release.
+
+ * "git config" used to choke with an insanely long line.
+   (merge ef/maint-strbuf-init later)
+
+ * "git diff --quiet" did not work well with --diff-filter.
+   (merge jk/diff-not-so-quick later)
+
+ * "git status -z" did not default to --porcelain output format.
+   (merge bc/maint-status-z-to-use-porcelain later)

+Git v1.7.7.1 Release Notes
+==========================
+
+Fixes since v1.7.7
+------------------
+
+ * On some BSD systems, adding +s bit on directories is detrimental
+   (it is not necessary on BSD to begin with). "git init --shared"
+   has been updated to take this into account without extra makefile
+   settings on platforms the Makefile knows about.
+
+ * After incorrectly written third-party tools store a tag object in
+   HEAD, git diagnosed it as a repository corruption and refused to
+   proceed in order to avoid spreading the damage. We now gracefully
+   recover from such a situation by pretending as if the commit that
+   is pointed at by the tag were in HEAD.
+
+ * "git apply --whitespace=error" did not bother to report the exact
+   line number in the patch that introduced new blank lines at the end
+   of the file.
+
+ * "git apply --index" did not check corrupted patch.
+
+ * "git checkout $tree $directory/" resurrected paths locally removed or
+   modified only in the working tree in $directory/ that did not appear
+   in $directory of the given $tree. They should have been kept intact.
+
+ * "git diff $tree $path" used to apply the pathspec at the output stage,
+   reading the whole tree, wasting resources.
+
+ * The code to check for updated submodules during a "git fetch" of the
+   superproject had an unnecessary quadratic loop.
+
+ * "git fetch" from a large bundle did not enable the progress output.
+
+ * When "git fsck --lost-and-found" found that an empty blob object in the
+   object store is unreachable, it incorrectly reported an error after
+   writing the lost blob out successfully.
+
+ * "git filter-branch" did not refresh the index before checking that the
+   working tree was clean.
+
+ * "git grep $tree" when run with multiple threads had an unsafe access to
+   the object database that should have been protected with mutex.
+
+ * The "--ancestry-path" option to "git log" and friends misbehaved in a
+   history with complex criss-cross merges and showed an uninteresting
+   side history as well.
+
+ * Test t1304 assumed LOGNAME is always set, which may not be true on
+   some systems.
+
+ * Tests with --valgrind failed to find "mergetool" scriptlets.
+
+ * "git patch-id" miscomputed the patch-id in a patch that has a line longer
+   than 1kB.
+
+ * When an "exec" insn failed after modifying the index and/or the working
+   tree during "rebase -i", we now check and warn that the changes need to
+   be cleaned up.

+Git v1.7.7.2 Release Notes
+==========================
+
+Fixes since v1.7.7.1
+--------------------
+
+ * We used to drop error messages from libcurl on certain kinds of
+   errors.
+
+ * Error report from smart HTTP transport, when the connection was
+   broken in the middle of a transfer, showed a useless message on
+   a corrupt packet.
+
+ * "git fetch --prune" was unsafe when used with refspecs from the
+   command line.
+
+ * The attribute mechanism did not use case insensitive match when
+   core.ignorecase was set.
+
+ * "git bisect" did not notice when it failed to update the working tree
+   to the next commit to be tested.
+
+ * "git config --bool --get-regexp" failed to separate the variable name
+   and its value "true" when the variable is defined without "= true".
+
+ * "git remote rename $a $b" were not careful to match the remote name
+   against $a (i.e. source side of the remote nickname).
+
+ * "git mergetool" did not use its arguments as pathspec, but as a path to
+   the file that may not even have any conflict.
+
+ * "git diff --[num]stat" used to use the number of lines of context
+   different from the default, potentially giving different results from
+   "git diff | diffstat" and confusing the users.
+
+ * "git pull" and "git rebase" did not work well even when GIT_WORK_TREE is
+   set correctly with GIT_DIR if the current directory is outside the working
+   tree.
+
+ * "git send-email" did not honor the configured hostname when restarting
+   the HELO/EHLO exchange after switching TLS on.
+
+ * "gitweb" used to produce a non-working link while showing the contents
+   of a blob, when JavaScript actions are enabled.

+

+   html/manpage are no longer in the source repository.
+
+ * The logic to optimize the locality of the data in a pack introduced in
+   1.7.7 was grossly inefficient.
+
+ * The logic to filter out forked projects in the project list in
+   "gitweb" was broken for some time.
+
+ * "git branch -m/-M" advertised to update RENAME_REF ref in the
+   commit log message that introduced the feature but not anywhere in
+   the documentation, and never did update such a ref anyway. This
+   undocumented misfeature that did not exist has been excised.

+Git v1.7.7 Release Notes
+========================
+
+Updates since v1.7.6
+--------------------
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Interix, Cygwin and Minix ports got updated.
+
+ * Various updates to git-p4 (in contrib/), fast-import, and git-svn.
+
+ * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
+   before reading from gitweb_config.perl or from /etc/gitweb.conf
+   (this last one is read only when per-repository gitweb_config.perl
+   does not exist).
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+   functions can compress or uncompress more than 4GB data in one call on
+   platforms with 64-bit long, which has been corrected.
+
+ * Git now recognizes loose objects written by other implementations that
+   use a non-standard window size for zlib deflation (e.g. Agit running on
+   Android with 4kb window). We used to reject anything that was not
+   deflated with 32kb window.
+
+ * Interaction between the use of pager and coloring of the output has
+   been improved, especially when a command that is not built-in was
+   involved.
+
+ * "git am" learned to pass the "--exclude=<path>" option through to underlying
+   "git apply".
+
+ * You can now feed many empty lines before feeding an mbox file to
+   "git am".
+
+ * "git archive" can be told to pass the output to gzip compression and
+   produce "archive.tar.gz".
+
+ * "git bisect" can be used in a bare repository (provided that the test
+   you perform per each iteration does not need a working tree, of
+   course).
+
+ * The length of abbreviated object names in "git branch -v" output
+   now honors the core.abbrev configuration variable.
+
+ * "git check-attr" can take relative paths from the command line.
+
+ * "git check-attr" learned an "--all" option to list the attributes for a
+   given path.
+
+ * "git checkout" (both the code to update the files upon checking out a
+   different branch and the code to checkout a specific set of files) learned
+   to stream the data from object store when possible, without having to
+   read the entire contents of a file into memory first. An earlier round
+   of this code that is not in any released version had a large leak but
+   now it has been plugged.
+
+ * "git clone" can now take a "--config key=value" option to set the
+   repository configuration options that affect the initial checkout.
+
+ * "git commit <paths>..." now lets you feed relative pathspecs that
+   refer to outside your current subdirectory.
+
+ * "git diff --stat" learned a --stat-count option to limit the output of
+   a diffstat report.
+
+ * "git diff" learned a "--histogram" option to use a different diff
+   generation machinery stolen from jgit, which might give better
+   performance.
+
+ * "git diff" had a weird worst case behaviour that can be triggered
+   when comparing files with potentially many places that could match.
+
+ * "git fetch", "git push" and friends no longer show connection
+   errors for addresses that couldn't be connected to when at least one
+   address succeeds (this is arguably a regression but a deliberate
+   one).
+
+ * "git grep" learned "--break" and "--heading" options, to let users mimic
+   the output format of "ack".
+
+ * "git grep" learned a "-W" option that shows wider context using the same
+   logic used by "git diff" to determine the hunk header.
+
+ * Invoking the low-level "git http-fetch" without "-a" option (which
+   git itself never did---normal users should not have to worry about
+   this) is now deprecated.
+
+ * The "--decorate" option to "git log" and its family learned to
+   highlight grafted and replaced commits.
+
+ * "git rebase master topci" no longer spews usage hints after giving
+   the "fatal: no such branch: topci" error message.
+
+ * The recursive merge strategy implementation got a fairly large
+   fix for many corner cases that may rarely happen in real world
+   projects (it has been verified that none of the 16000+ merges in
+   the Linux kernel history back to v2.6.12 is affected with the
+   corner case bugs this update fixes).
+
+ * "git stash" learned an "--include-untracked option".
+
+ * "git submodule update" used to stop at the first error updating a
+   submodule; it now goes on to update other submodules that can be
+   updated, and reports the ones with errors at the end.
+
+ * "git push" can be told with the "--recurse-submodules=check" option to
+   refuse pushing of the supermodule, if any of its submodules'
+   commits hasn't been pushed out to their remotes.
+
+ * "git upload-pack" and "git receive-pack" learned to pretend that only a
+   subset of the refs exist in a repository. This may help a site to
+   put many tiny repositories into one repository (this would not be
+   useful for larger repositories as repacking would be problematic).
+
+ * "git verify-pack" has been rewritten to use the "index-pack" machinery
+   that is more efficient in reading objects in packfiles.
+
+ * test scripts for gitweb tried to run even when CGI-related perl modules
+   are not installed; they now exit early when the latter are unavailable.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.6
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
+included in this release.
+
+ * "git branch -m" and "git checkout -b" incorrectly allowed the tip
+   of the branch that is currently checked out updated.

+
+ * "git apply --check" did not error out when given an empty input
+   without any patch.

+   fell into an infinite loop with a rare input.
+
+ * The function header pattern for files with "diff=cpp" attribute did
+   not consider "type *funcname(type param1,..." as the beginning of a
+   function.
+
+ * The error message from "git diff" and "git status" when they fail
+   to inspect changes in submodules did not report which submodule they
+   had trouble with.
+
+ * After fetching from a remote that has very long refname, the reporting
+   output could have corrupted by overrunning a static buffer.
+
+ * "git pack-objects" avoids creating cyclic dependencies among deltas
+   when seeing a broken packfile that records the same object in both
+   the deflated form and as a delta.

+Git v1.7.8.2 Release Notes
+==========================
+
+Fixes since v1.7.8.1
+--------------------
+
+ * Porcelain commands like "git reset" did not distinguish deletions
+   and type-changes from ordinary modification, and reported them with
+   the same 'M' moniker. They now use 'D' (for deletion) and 'T' (for
+   type-change) to match "git status -s" and "git diff --name-status".
+
+ * The configuration file parser used for sizes (e.g. bigFileThreshold)
+   did not correctly interpret 'g' suffix.
+
+ * The replacement implementation for snprintf used on platforms with
+   native snprintf that is broken did not use va_copy correctly.
+
+ * LF-to-CRLF streaming filter replaced all LF with CRLF, which might
+   be technically correct but not friendly to people who are trying
+   to recover from earlier mistakes of using CRLF in the repository
+   data in the first place. It now refrains from doing so for LF that
+   follows a CR.
+
+ * git native connection going over TCP (not over SSH) did not set
+   SO_KEEPALIVE option which failed to receive link layer errors.
+
+ * "git branch -m <current branch> HEAD" is an obvious no-op but was not
+   allowed.
+
+ * "git checkout -m" did not recreate the conflicted state in a "both
+   sides added, without any common ancestor version" conflict
+   situation.
+
+ * "git cherry-pick $commit" (not a range) created an unnecessary
+   sequencer state and interfered with valid workflow to use the
+   command during a session to cherry-pick multiple commits.
+
+ * You could make "git commit" segfault by giving the "--no-message"
+   option.
+
+ * "fast-import" did not correctly update an existing notes tree,
+   possibly corrupting the fan-out.
+
+ * "git fetch-pack" accepted unqualified refs that do not begin with
+   refs/ by mistake and compensated it by matching the refspec with
+   tail-match, which was doubly wrong. This broke fetching from a
+   repository with a funny named ref "refs/foo/refs/heads/master" and a
+   'master' branch with "git fetch-pack refs/heads/master", as the
+   command incorrectly considered the former a "match".
+
+ * "git log --follow" did not honor the rename threshold score given
+   with the -M option (e.g. "-M50%").
+
+ * "git mv" gave suboptimal error/warning messages when it overwrites
+   target files. It also did not pay attention to "-v" option.
+
+ * Authenticated "git push" over dumb HTTP were broken with a recent
+   change and failed without asking for password when username is
+   given.
+
+ * "git push" to an empty repository over HTTP were broken with a
+   recent change to the ref handling.
+
+ * "git push -v" forgot how to be verbose by mistake. It now properly
+   becomes verbose when asked to.
+
+ * When a "reword" action in "git rebase -i" failed to run "commit --amend",
+   we did not give the control back to the user to resolve the situation, and
+   instead kept the original commit log message.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8 Release Notes
+========================
+
+Updates since v1.7.7
+--------------------
+
+ * Some git-svn, git-gui, git-p4 (in contrib) and msysgit updates.
+
+ * Updates to bash completion scripts.
+
+ * The build procedure has been taught to take advantage of computed
+   dependency automatically when the compiler supports it.
+
+ * The date parser now accepts timezone designators that lack minutes
+   part and also has a colon between "hh:mm".
+
+ * The contents of the /etc/mailname file, if exists, is used as the
+   default value of the hostname part of the committer/author e-mail.
+
+ * "git am" learned how to read from patches generated by Hg.
+
+ * "git archive" talking with a remote repository can report errors
+   from the remote side in a more informative way.
+
+ * "git branch" learned an explicit --list option to ask for branches
+   listed, optionally with a glob matching pattern to limit its output.
+
+ * "git check-attr" learned "--cached" option to look at .gitattributes
+   files from the index, not from the working tree.
+
+ * Variants of "git cherry-pick" and "git revert" that take multiple
+   commits learned to "--continue" and "--abort".
+
+ * "git daemon" gives more human readable error messages to clients
+   using ERR packets when appropriate.
+
+ * Errors at the network layer is logged by "git daemon".
+
+ * "git diff" learned "--minimal" option to spend extra cycles to come
+   up with a minimal patch output.
+
+ * "git diff" learned "--function-context" option to show the whole
+   function as context that was affected by a change.
+
+ * "git difftool" can be told to skip launching the tool for a path by
+   answering 'n' to its prompt.
+
+ * "git fetch" learned to honor transfer.fsckobjects configuration to
+   validate the objects that were received from the other end, just like
+   "git receive-pack" (the receiving end of "git push") does.
+
+ * "git fetch" makes sure that the set of objects it received from the
+   other end actually completes the history before updating the refs.
+   "git receive-pack" (the receiving end of "git push") learned to do the
+   same.
+
+ * "git fetch" learned that fetching/cloning from a regular file on the
+   filesystem is not necessarily a request to unpack a bundle file; the
+   file could be ".git" with "gitdir: <path>" in it.
+
+ * "git for-each-ref" learned "%(contents:subject)", "%(contents:body)"
+   and "%(contents:signature)". The last one is useful for signed tags.
+
+ * "git grep" used to incorrectly pay attention to .gitignore files
+   scattered in the directory it was working in even when "--no-index"
+   option was used. It no longer does this. The "--exclude-standard"
+   option needs to be given to explicitly activate the ignore
+   mechanism.
+
+ * "git grep" learned "--untracked" option, where given patterns are
+    searched in untracked (but not ignored) files as well as tracked
+    files in the working tree, so that matches in new but not yet
+    added files do not get missed.
+
+ * The recursive merge backend no longer looks for meaningless
+   existing merges in submodules unless in the outermost merge.
+
+ * "git log" and friends learned "--children" option.
+
+ * "git ls-remote" learned to respond to "-h"(elp) requests.
+
+ * "mediawiki" remote helper can interact with (surprise!) MediaWiki
+   with "git fetch" & "git push".
+
+ * "git merge" learned the "--edit" option to allow users to edit the
+   merge commit log message.
+
+ * "git rebase -i" can be told to use special purpose editor suitable
+   only for its insn sheet via sequence.editor configuration variable.
+
+ * "git send-email" learned to respond to "-h"(elp) requests.
+
+ * "git send-email" allows the value given to sendemail.aliasfile to begin
+   with "~/" to refer to the $HOME directory.
+
+ * "git send-email" forces use of Authen::SASL::Perl to work around
+   issues between Authen::SASL::Cyrus and AUTH PLAIN/LOGIN.
+
+ * "git stash" learned "--include-untracked" option to stash away
+   untracked/ignored cruft from the working tree.
+
+ * "git submodule clone" does not leak an error message to the UI
+   level unnecessarily anymore.
+
+ * "git submodule update" learned to honor "none" as the value for
+   submodule.<name>.update to specify that the named submodule should
+   not be checked out by default.
+
+ * When populating a new submodule directory with "git submodule init",
+   the $GIT_DIR metainformation directory for submodules is created inside
+   $GIT_DIR/modules/<name>/ directory of the superproject and referenced
+   via the gitfile mechanism. This is to make it possible to switch
+   between commits in the superproject that has and does not have the
+   submodule in the tree without re-cloning.
+
+ * "gitweb" leaked unescaped control characters from syntax hiliter
+   outputs.
+
+ * "gitweb" can be told to give custom string at the end of the HTML
+   HEAD element.
+
+ * "gitweb" now has its own manual pages.
+
+
+Also contains other documentation updates and minor code cleanups.
+
+
+Fixes since v1.7.7
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.7.X maintenance track are
+included in this release.
+
+ * HTTP transport did not use pushurl correctly, and also did not tell
+   what host it is trying to authenticate with when asking for
+   credentials.
+   (merge deba493 jk/http-auth later to maint).
+
+ * "git blame" was aborted if started from an uncommitted content and
+   the path had the textconv filter in effect.
+   (merge 8518088 ss/blame-textconv-fake-working-tree later to maint).
+
+ * Adding many refs to the local repository in one go (e.g. "git fetch"
+   that fetches many tags) and looking up a ref by name in a repository
+   with too many refs were unnecessarily slow.
+   (merge 17d68a54d jp/get-ref-dir-unsorted later to maint).
+
+ * Report from "git commit" on untracked files was confused under
+   core.ignorecase option.
+   (merge 395c7356 jk/name-hash-dirent later to maint).
+
+ * "git merge" did not understand ":/<pattern>" as a way to name a commit.
+
+ " "git push" on the receiving end used to call post-receive and post-update
+   hooks for attempted removal of non-existing refs.
+   (merge 160b81ed ph/push-to-delete-nothing later to maint).
+
+ * Help text for "git remote set-url" and "git remote set-branches"
+   were misspelled.
+   (merge c49904e fc/remote-seturl-usage-fix later to maint).
+   (merge 656cdf0 jc/remote-setbranches-usage-fix later to maint).

+Git v1.7.9.1 Release Notes
+==========================
+
+Fixes since v1.7.9
+------------------
+
+ * The makefile allowed environment variable X seep into it result in
+   command names suffixed with unnecessary strings.
+
+ * The set of included header files in compat/inet-{ntop,pton}
+   wrappers was updated for Windows some time ago, but in a way that
+   broke Solaris build.
+
+ * rpmbuild noticed an unpackaged but installed *.mo file and failed.
+
+ * Subprocesses spawned from various git programs were often left running
+   to completion even when the top-level process was killed.
+
+ * "git add -e" learned not to show a diff for an otherwise unmodified
+   submodule that only has uncommitted local changes in the patch
+   prepared by for the user to edit.
+
+ * Typo in "git branch --edit-description my-tpoic" was not diagnosed.
+
+ * Using "git grep -l/-L" together with options -W or --break may not
+   make much sense as the output is to only count the number of hits
+   and there is no place for file breaks, but the latter options made
+   "-l/-L" to miscount the hits.
+
+ * "git log --first-parent $pathspec" did not stay on the first parent
+   chain and veered into side branch from which the whole change to the
+   specified paths came.
+
+ * "git merge --no-edit $tag" failed to honor the --no-edit option.
+
+ * "git merge --ff-only $tag" failed because it cannot record the
+   required mergetag without creating a merge, but this is so common
+   operation for branch that is used _only_ to follow the upstream, so
+   it was changed to allow fast-forwarding without recording the mergetag.
+
+ * "git mergetool" now gives an empty file as the common base version
+   to the backend when dealing with the "both sides added, differently"
+   case.
+
+ * "git push -q" was not sufficiently quiet.
+
+ * When "git push" fails to update any refs, the client side did not
+   report an error correctly to the end user.
+
+ * "rebase" and "commit --amend" failed to work on commits with ancient
+   timestamps near year 1970.
+
+ * When asking for a tag to be pulled, "request-pull" did not show the
+   name of the tag prefixed with "tags/", which would have helped older
+   clients.
+
+ * "git submodule add $path" forgot to recompute the name to be stored
+   in .gitmodules when the submodule at $path was once added to the
+   superproject and already initialized.
+
+ * Many small corner case bugs on "git tag -n" was corrected.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9.2 Release Notes
+==========================
+
+Fixes since v1.7.9.1
+--------------------
+
+ * Bash completion script (in contrib/) did not like a pattern that
+   begins with a dash to be passed to __git_ps1 helper function.
+
+ * Adaptation of the bash completion script (in contrib/) for zsh
+   incorrectly listed all subcommands when "git <TAB><TAB>" was given
+   to ask for list of porcelain subcommands.
+
+ * The build procedure for profile-directed optimized binary was not
+   working very well.
+
+ * Some systems need to explicitly link -lcharset to get locale_charset().
+
+ * t5541 ignored user-supplied port number used for HTTP server testing.
+
+ * The error message emitted when we see an empty loose object was
+   not phrased correctly.
+
+ * The code to ask for password did not fall back to the terminal
+   input when GIT_ASKPASS is set but does not work (e.g. lack of X
+   with GUI askpass helper).
+
+ * We failed to give the true terminal width to any subcommand when
+   they are invoked with the pager, i.e. "git -p cmd".
+
+ * map_user() was not rewriting its output correctly, which resulted
+   in the user visible symptom that "git blame -e" sometimes showed
+   excess '>' at the end of email addresses.
+
+ * "git checkout -b" did not allow switching out of an unborn branch.
+
+ * When you have both .../foo and .../foo.git, "git clone .../foo" did not
+   favor the former but the latter.
+
+ * "git commit" refused to create a commit when entries added with
+   "add -N" remained in the index, without telling Git what their content
+   in the next commit should be. We should have created the commit without
+   these paths.
+
+ * "git diff --stat" said "files", "insertions", and "deletions" even
+   when it is showing one "file", one "insertion" or one "deletion".
+
+ * The output from "git diff --stat" for two paths that have the same
+   amount of changes showed graph bars of different length due to the
+   way we handled rounding errors.
+
+ * "git grep" did not pay attention to -diff (hence -binary) attribute.
+
+ * The transport programs (fetch, push, clone)ignored --no-progress
+   and showed progress when sending their output to a terminal.
+
+ * Sometimes error status detected by a check in an earlier phase of
+   "git receive-pack" (the other end of "git push") was lost by later
+   checks, resulting in false indication of success.
+
+ * "git rev-list --verify" sometimes skipped verification depending on
+   the phase of the moon, which dates back to 1.7.8.x series.
+
+ * Search box in "gitweb" did not accept non-ASCII characters correctly.
+
+ * Search interface of "gitweb" did not show multiple matches in the same file
+   correctly.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9.3 Release Notes
+==========================
+
+Fixes since v1.7.9.2
+--------------------
+
+ * "git p4" (in contrib/) submit the changes to a wrong place when the
+   "--use-client-spec" option is set.
+
+ * The config.mak.autogen generated by optional autoconf support tried
+   to link the binary with -lintl even when libintl.h is missing from
+   the system.
+
+ * When the filter driver exits before reading the content before the
+   main git process writes the contents to be filtered to the pipe to
+   it, the latter could be killed with SIGPIPE instead of ignoring
+   such an event as an error.
+
+ * "git add --refresh <pathspec>" used to warn about unmerged paths
+   outside the given pathspec.
+
+ * The bulk check-in codepath in "git add" streamed contents that
+   needs smudge/clean filters without running them, instead of punting
+   and delegating to the codepath to run filters after slurping
+   everything to core.
+
+ * "git branch --with $that" assumed incorrectly that the user will never
+   ask the question with nonsense value in $that.
+
+ * "git bundle create" produced a corrupt bundle file upon seeing
+   commits with excessively long subject line.
+
+ * When a remote helper exits before reading the blank line from the
+   main git process to signal the end of commands, the latter could be
+   killed with SIGPIPE. Instead we should ignore such event as a
+   non-error.
+
+ * The commit log template given with "git merge --edit" did not have
+   a short instructive text like what "git commit" gives.
+
+ * "git rev-list --verify-objects -q" omitted the extra verification
+   it needs to do over "git rev-list --objects -q" by mistake.
+
+ * "gitweb" used to drop warnings in the log file when "heads" view is
+   accessed in a repository whose HEAD does not point at a valid
+   branch.
+
+ * An invalid regular expression pattern given by an end user made
+   "gitweb" to return garbled response.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9.4 Release Notes

+
+ * "git bundle" did not record boundary commits correctly when there

+
+ * "git diff-index" and its friends at the plumbing level showed the

+   info is dirty without actual difference when asked to produce a
+   patch. This was a longstanding bug that we could have fixed long
+   time ago.
+
+ * "gitweb" did use quotemeta() to prepare search string when asked to
+   do a fixed-string project search, but did not use it by mistake and
+   used the user-supplied string instead.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9 Release Notes
+========================
+
+Updates since v1.7.8
+--------------------
+
+ * gitk updates accumulated since early 2011.
+
+ * git-gui updated to 0.16.0.
+
+ * git-p4 (in contrib/) updates.
+
+ * Git uses gettext to translate its most common interface messages
+   into the user's language if translations are available and the
+   locale is appropriately set. Distributors can drop new PO files
+   in po/ to add new translations.
+
+ * The code to handle username/password for HTTP transactions used in
+   "git push" & "git fetch" learned to talk "credential API" to
+   external programs to cache or store them, to allow integration with
+   platform native keychain mechanisms.
+
+ * The input prompts in the terminal use our own getpass() replacement
+   when possible. HTTP transactions used to ask for the username without
+   echoing back what was typed, but with this change you will see it as
+   you type.
+
+ * The internals of "revert/cherry-pick" have been tweaked to prepare
+   building more generic "sequencer" on top of the implementation that
+   drives them.
+
+ * "git rev-parse FETCH_HEAD" after "git fetch" without specifying
+   what to fetch from the command line will now show the commit that
+   would be merged if the command were "git pull".
+
+ * "git add" learned to stream large files directly into a packfile
+   instead of writing them into individual loose object files.
+
+ * "git checkout -B <current branch> <elsewhere>" is a more intuitive
+   way to spell "git reset --keep <elsewhere>".
+
+ * "git checkout" and "git merge" learned "--no-overwrite-ignore" option
+   to tell Git that untracked and ignored files are not expendable.
+
+ * "git commit --amend" learned "--no-edit" option to say that the
+   user is amending the tree being recorded, without updating the
+   commit log message.
+
+ * "git commit" and "git reset" re-learned the optimization to prime
+   the cache-tree information in the index, which makes it faster to
+   write a tree object out after the index entries are updated.
+
+ * "git commit" detects and rejects an attempt to stuff NUL byte in
+   the commit log message.
+
+ * "git commit" learned "-S" to GPG-sign the commit; this can be shown
+   with the "--show-signature" option to "git log".
+
+ * fsck and prune are relatively lengthy operations that still go
+   silent while making the end-user wait. They learned to give progress
+   output like other slow operations.
+
+ * The set of built-in function-header patterns for various languages
+   knows MATLAB.
+
+ * "git log --format='<format>'" learned new %g[nNeE] specifiers to
+   show information from the reflog entries when walking the reflog
+   (i.e. with "-g").
+
+ * "git pull" can be used to fetch and merge an annotated/signed tag,
+   instead of the tip of a topic branch. The GPG signature from the
+   signed tag is recorded in the resulting merge commit for later
+   auditing.
+
+ * "git log" learned "--show-signature" option to show the signed tag
+   that was merged that is embedded in the merge commit. It also can
+   show the signature made on the commit with "git commit -S".
+
+ * "git branch --edit-description" can be used to add descriptive text
+   to explain what a topic branch is about.
+
+ * "git fmt-merge-msg" learned to take the branch description into
+   account when preparing a merge summary that "git merge" records
+   when merging a local branch.
+
+ * "git request-pull" has been updated to convey more information
+   useful for integrators to decide if a topic is worth merging and
+   what is pulled is indeed what the requestor asked to pull,
+   including:
+
+   - the tip of the branch being requested to be merged;
+   - the branch description describing what the topic is about;
+   - the contents of the annotated tag, when requesting to pull a tag.
+
+ * "git pull" learned to notice 'pull.rebase' configuration variable,
+   which serves as a global fallback for setting 'branch.<name>.rebase'
+   configuration variable per branch.
+
+ * "git tag" learned "--cleanup" option to control how the whitespaces
+   and empty lines in tag message are cleaned up.
+
+ * "gitweb" learned to show side-by-side diff.
+
+Also contains minor documentation updates and code clean-ups.
+

+Git v1.8.0.1 Release Notes
+==========================
+
+Fixes since v1.8.0
+------------------
+
+ * The configuration parser had an unnecessary hardcoded limit on
+   variable names that was not checked consistently.
+
+ * The "say" function in the test scaffolding incorrectly allowed
+   "echo" to interpret "\a" as if it were a C-string asking for a
+   BEL output.
+
+ * "git mergetool" feeds /dev/null as a common ancestor when dealing
+   with an add/add conflict, but p4merge backend cannot handle
+   it. Work it around by passing a temporary empty file.
+
+ * "git log -F -E --grep='<ere>'" failed to use the given <ere>
+   pattern as extended regular expression, and instead looked for the
+   string literally.
+
+ * "git grep -e pattern <tree>" asked the attribute system to read
+   "<tree>:.gitattributes" file in the working tree, which was
+   nonsense.
+
+ * A symbolic ref refs/heads/SYM was not correctly removed with "git
+   branch -d SYM"; the command removed the ref pointed by SYM
+   instead.
+
+ * Earlier we fixed documentation to hyphenate "remote-tracking branch"
+   to clarify that these are not a remote entity, but unhyphenated
+   spelling snuck in to a few places since then.
+
+ * "git pull --rebase" run while the HEAD is detached tried to find
+   the upstream branch of the detached HEAD (which by definition
+   does not exist) and emitted unnecessary error messages.
+
+ * The refs/replace hierarchy was not mentioned in the
+   repository-layout docs.
+
+ * Sometimes curl_multi_timeout() function suggested a wrong timeout
+   value when there is no file descriptors to wait on and the http
+   transport ended up sleeping for minutes in select(2) system call.
+   A workaround has been added for this.
+
+ * Various rfc2047 quoting issues around a non-ASCII name on the
+   From: line in the output from format-patch have been corrected.
+
+ * "git diff -G<pattern>" did not honor textconv filter when looking
+   for changes.
+
+ * Bash completion script (in contrib/) did not correctly complete a
+   lazy "git checkout $name_of_remote_tracking_branch_that_is_unique"
+   command line.
+
+ * RSS feed from "gitweb" had a xss hole in its title output.
+
+ * "git config --path $key" segfaulted on "[section] key" (a boolean
+   "true" spelled without "=", not "[section] key = true").
+
+ * "git checkout -b foo" while on an unborn branch did not say
+   "Switched to a new branch 'foo'" like other cases.
+
+Also contains other minor fixes and documentation updates.

+Git v1.8.0.2 Release Notes
+==========================
+
+Fixes since v1.8.0.1
+--------------------
+
+ * Various codepaths have workaround for a common misconfiguration to
+   spell "UTF-8" as "utf8", but it was not used uniformly.  Most
+   notably, mailinfo (which is used by "git am") lacked this support.
+
+ * We failed to mention a file without any content change but whose
+   permission bit was modified, or (worse yet) a new file without any
+   content in the "git diff --stat" output.
+
+ * When "--stat-count" hides a diffstat for binary contents, the total
+   number of added and removed lines at the bottom was computed
+   incorrectly.
+
+ * When "--stat-count" hides a diffstat for unmerged paths, the total
+   number of affected files at the bottom of the "diff --stat" output
+   was computed incorrectly.
+
+ * "diff --shortstat" miscounted the total number of affected files
+   when there were unmerged paths.
+
+ * "git p4" used to try expanding malformed "$keyword$" that spans
+   across multiple lines.
+
+ * "git update-ref -d --deref SYM" to delete a ref through a symbolic
+   ref that points to it did not remove it correctly.
+
+ * Syntax highlighting in "gitweb" was not quite working.
+
+Also contains other minor fixes and documentation updates.

+Git v1.8.0 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+In the next major release (not *this* one), we will change the
+behavior of the "git push" command.
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  We will use the "simple" semantics that pushes the
+current branch to the branch with the same name, only when the current
+branch is set to integrate with that remote branch.  There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable in this release.
+
+"git branch --set-upstream" is deprecated and may be removed in a
+relatively distant future.  "git branch [-u|--set-upstream-to]" has
+been introduced with a saner order of arguments.
+
+
+Updates since v1.7.12
+---------------------
+
+UI, Workflows & Features
+
+ * A credential helper for Win32 to allow access to the keychain of
+   the logged-in user has been added.
+
+ * An initial port to HP NonStop.
+
+ * A credential helper to allow access to the Gnome keyring has been
+   added.
+
+ * When "git am" sanitizes the "Subject:" line, we strip the prefix from
+   "Re: subject" and also from a less common "re: subject", but left
+   the even less common "RE: subject" intact.  Now we strip that too.
+
+ * It was tempting to say "git branch --set-upstream origin/master",
+   but that tells Git to arrange the local branch "origin/master" to
+   integrate with the currently checked out branch, which is highly
+   unlikely what the user meant.  The option is deprecated; use the
+   new "--set-upstream-to" (with a short-and-sweet "-u") option
+   instead.
+
+ * "git cherry-pick" learned the "--allow-empty-message" option to
+   allow it to replay a commit without any log message.
+
+ * After "git cherry-pick -s" gave control back to the user asking
+   help to resolve conflicts, concluding "git commit" used to need to
+   be run with "-s" if the user wants to sign it off; now the command
+   leaves the sign-off line in the log template.
+
+ * "git daemon" learned the "--access-hook" option to allow an
+   external command to decline service based on the client address,
+   repository path, etc.
+
+ * "git difftool --dir-diff" learned to use symbolic links to prepare
+   a temporary copy of the working tree when available.
+
+ * "git grep" learned to use a non-standard pattern type by default if
+   a configuration variable tells it to.
+
+ * Accumulated updates to "git gui" has been merged.
+
+ * "git log -g" learned the "--grep-reflog=<pattern>" option to limit
+   its output to commits with a reflog message that matches the given
+   pattern.
+
+ * "git merge-base" learned the "--is-ancestor A B" option to tell if A is
+   an ancestor of B.  The result is indicated by its exit status code.
+
+ * "git mergetool" now allows users to override the actual command used
+   with the mergetool.$name.cmd configuration variable even for built-in
+   mergetool backends.
+
+ * "git rebase -i" learned the "--edit-todo" option to open an editor
+   to edit the instruction sheet.
+
+
+Foreign Interface
+
+ * "git svn" has been updated to work with SVN 1.7.
+
+ * "git p4" learned the "--conflicts" option to specify what to do when
+   encountering a conflict during "p4 submit".
+
+
+Performance, Internal Implementation, etc.
+
+ * Git ships with a fall-back regexp implementation for platforms with
+   buggy regexp library, but it was easy for people to keep using their
+   platform regexp by mistake.  A new test has been added to check this.
+
+ * The "check-docs" build target has been updated and greatly
+   simplified.
+
+ * The test suite is run under MALLOC_CHECK_ when running with a glibc
+   that supports the feature.
+
+ * The documentation in the TeXinfo format was using indented output
+   for materials meant to be examples that are better typeset in
+   monospace.
+
+ * Compatibility wrapper around some mkdir(2) implementations that
+   reject parameters with trailing slash has been introduced.
+
+ * Compatibility wrapper for systems that lack usable setitimer() has
+   been added.
+
+ * The option parsing of "git checkout" had error checking, dwim and
+   defaulting missing options, all mixed in the code, and issuing an
+   appropriate error message with useful context was getting harder.
+   The code has been reorganized to allow giving a proper diagnosis
+   when the user says "git checkout -b -t foo bar" (e.g. "-t" is not a
+   good name for a branch).
+
+ * Many internal uses of a "git merge-base" equivalent were only to see
+   if one commit fast-forwards to the other, which did not need the
+   full set of merge bases to be computed. They have been updated to
+   use less expensive checks.
+
+ * The heuristics to detect and silently convert latin1 to utf8 when
+   we were told to use utf-8 in the log message has been transplanted
+   from "mailinfo" to "commit" and "commit-tree".
+
+ * Messages given by "git <subcommand> -h" from many subcommands have
+   been marked for translation.
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.12
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.12 in the
+maintenance track are contained in this release (see release notes
+to them for details).
+
+ * The attribute system may be asked for a path that itself or its
+   leading directories no longer exists in the working tree, and it is
+   fine if we cannot open .gitattribute file in such a case.  Failure
+   to open per-directory .gitattributes with error status other than
+   ENOENT and ENOTDIR should be diagnosed, but it wasn't.
+
+ * When looking for $HOME/.gitconfig etc., it is OK if we cannot read
+   them because they do not exist, but we did not diagnose existing
+   files that we cannot read.
+
+ * When "git am" is fed an input that has multiple "Content-type: ..."
+   header, it did not grok charset= attribute correctly.
+
+ * "git am" mishandled a patch attached as application/octet-stream
+   (e.g. not text/*); Content-Transfer-Encoding (e.g. base64) was not
+   honored correctly.
+
+ * "git blame MAKEFILE" run in a history that has "Makefile" but not
+   "MAKEFILE" should say "No such file MAKEFILE in HEAD", but got
+   confused on a case insensitive filesystem and failed to do so.
+
+ * Even during a conflicted merge, "git blame $path" always meant to
+   blame uncommitted changes to the "working tree" version; make it
+   more useful by showing cleanly merged parts as coming from the other
+   branch that is being merged.
+
+ * It was unclear in the documentation for "git blame" that it is
+   unnecessary for users to use the "--follow" option.
+
+ * Output from "git branch -v" contains "(no branch)" that could be
+   localized, but the code to align it along with the names of
+   branches was counting in bytes, not in display columns.
+
+ * "git cherry-pick A C B" used to replay changes in A and then B and
+   then C if these three commits had committer timestamps in that
+   order, which is not what the user who said "A C B" naturally
+   expects.
+
+ * A repository created with "git clone --single" had its fetch
+   refspecs set up just like a clone without "--single", leading the
+   subsequent "git fetch" to slurp all the other branches, defeating
+   the whole point of specifying "only this branch".
+
+ * Documentation talked about "first line of commit log" when it meant
+   the title of the commit.  The description was clarified by defining
+   how the title is decided and rewording the casual mention of "first
+   line" to "title".
+
+ * "git cvsimport" did not thoroughly cleanse tag names that it
+   inferred from the names of the tags it obtained from CVS, which
+   caused "git tag" to barf and stop the import in the middle.
+
+ * Earlier we made the diffstat summary line that shows the number of
+   lines added/deleted localizable, but it was found irritating having
+   to see them in various languages on a list whose discussion language
+   is English, and this change has been reverted.
+
+ * "git fetch --all", when passed "--no-tags", did not honor the
+   "--no-tags" option while fetching from individual remotes (the same
+   issue existed with "--tags", but the combination "--all --tags" makes
+   much less sense than "--all --no-tags").
+
+ * "git fetch" over http had an old workaround for an unlikely server
+   misconfiguration; it turns out that this hurts debuggability of the
+   configuration in general, and has been reverted.
+
+ * "git fetch" over http advertised that it supports "deflate", which
+   is much less common, and did not advertise the more common "gzip" on
+   its Accept-Encoding header.
+
+ * "git fetch" over the dumb-http revision walker could segfault when
+   curl's multi interface was used.
+
+ * "git gc --auto" notified the user that auto-packing has triggered
+    even under the "--quiet" option.
+
+ * After "gitk" showed the contents of a tag, neither "Reread
+   references" nor "Reload" updated what is shown as the
+   contents of it when the user overwrote the tag with "git tag -f".
+
+ * "git log --all-match --grep=A --grep=B" ought to show commits that
+   mention both A and B, but when these three options are used with
+   --author or --committer, it showed commits that mention either A or
+   B (or both) instead.
+
+ * The "-Xours" backend option to "git merge -s recursive" was ignored
+   for binary files.
+
+ * "git p4", when "--use-client-spec" and "--detect-branches" are used
+   together, misdetected branches.
+
+ * "git receive-pack" (the counterpart to "git push") did not give
+   progress output while processing objects it received to the puser
+   when run over the smart-http protocol.
+
+ * When you misspell the command name you give to the "exec" action in
+   the "git rebase -i" instruction sheet you were told that 'rebase' is not a
+   git subcommand from "git rebase --continue".
+
+ * The subcommand in "git remote" to remove a defined remote was
+   "rm" and the command did not take a fully-spelled "remove".
+
+ * The interactive prompt that "git send-email" gives was error prone. It
+   asked "What e-mail address do you want to use?" with the address it
+   guessed (correctly) the user would want to use in its prompt,
+   tempting the user to say "y". But the response was taken as "No,
+   please use 'y' as the e-mail address instead", which is most
+   certainly not what the user meant.
+
+ * "git show --format='%ci'" did not give the timestamp correctly for
+   commits created without human readable name on the "committer" line.
+
+ * "git show --quiet" ought to be a synonym for "git show -s", but
+   wasn't.
+
+ * "git submodule frotz" was not diagnosed as "frotz" being an unknown
+   subcommand to "git submodule"; the user instead got a complaint
+   that "git submodule status" was run with an unknown path "frotz".
+
+ * "git status" honored the ignore=dirty settings in .gitmodules but
+   "git commit" didn't.
+
+ * "gitweb" did not give the correct committer timezone in its feed
+   output due to a typo.

+Git 1.8.1.1 Release Notes
+=========================
+
+Fixes since v1.8.1
+------------------
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.
+
+ * When attempting to read the XDG-style $HOME/.config/git/config and
+   finding that $HOME/.config/git is a file, we gave a wrong error
+   message, instead of treating the case as "a custom config file does
+   not exist there" and moving on.
+
+ * After failing to create a temporary file using mkstemp(), failing
+   pathname was not reported correctly on some platforms.
+
+ * http transport was wrong to ask for the username when the
+   authentication is done by certificate identity.
+
+ * The behaviour visible to the end users was confusing, when they
+   attempt to kill a process spawned in the editor that was in turn
+   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
+   signal and die.  We ignore these signals now.
+
+ * A child process that was killed by a signal (e.g. SIGINT) was
+   reported in an inconsistent way depending on how the process was
+   spawned by us, with or without a shell in between.
+
+ * After "git add -N" and then writing a tree object out of the
+   index, the cache-tree data structure got corrupted.
+
+ * "git apply" misbehaved when fixing whitespace breakages by removing
+   excess trailing blank lines in some corner cases.
+
+ * A tar archive created by "git archive" recorded a directory in a
+   way that made NetBSD's implementation of "tar" sometimes unhappy.
+
+ * When "git clone --separate-git-dir=$over_there" is interrupted, it
+   failed to remove the real location of the $GIT_DIR it created.
+   This was most visible when interrupting a submodule update.
+
+ * "git fetch --mirror" and fetch that uses other forms of refspec
+   with wildcard used to attempt to update a symbolic ref that match
+   the wildcard on the receiving end, which made little sense (the
+   real ref that is pointed at by the symbolic ref would be updated
+   anyway).  Symbolic refs no longer are affected by such a fetch.
+
+ * The "log --graph" codepath fell into infinite loop in some
+   corner cases.
+
+ * "git merge" started calling prepare-commit-msg hook like "git
+   commit" does some time ago, but forgot to pay attention to the exit
+   status of the hook.
+
+ * "git pack-refs" that ran in parallel to another process that
+   created new refs had a race that can lose new ones.
+
+ * When a line to be wrapped has a solid run of non space characters
+   whose length exactly is the wrap width, "git shortlog -w" failed
+   to add a newline after such a line.
+
+ * The way "git svn" asked for password using SSH_ASKPASS and
+   GIT_ASKPASS was not in line with the rest of the system.
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * When autoconf is used, any build on a different commit always ran
+   "config.status --recheck" even when unnecessary.
+
+ * Some scripted programs written in Python did not get updated when
+   PYTHON_PATH changed.
+
+ * We have been carrying a translated and long-unmaintained copy of an
+   old version of the tutorial; removed.
+
+ * Portability issues in many self-test scripts have been addressed.
+
+
+Also contains other minor fixes and documentation updates.

+Git 1.8.1.2 Release Notes
+=========================
+
+Fixes since v1.8.1.1
+--------------------
+
+ * An element on GIT_CEILING_DIRECTORIES list that does not name the
+   real path to a directory (i.e. a symbolic link) could have caused
+   the GIT_DIR discovery logic to escape the ceiling.
+
+ * Command line completion for "tcsh" emitted an unwanted space
+   after completing a single directory name.
+
+ * Command line completion leaked an unnecessary error message while
+   looking for possible matches with paths in <tree-ish>.
+
+ * "git archive" did not record uncompressed size in the header when
+   streaming a zip archive, which confused some implementations of unzip.
+
+ * When users spelled "cc:" in lowercase in the fake "header" in the
+   trailer part, "git send-email" failed to pick up the addresses from
+   there. As e-mail headers field names are case insensitive, this
+   script should follow suit and treat "cc:" and "Cc:" the same way.

+Git 1.8.1.3 Release Notes
+=========================
+
+Fixes since v1.8.1.2
+--------------------
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.  The fix for this in 1.8.1.2 had
+   performance degradations.
+
+ * Command line completion code was inadvertently made incompatible with
+   older versions of bash by using a newer array notation.
+
+ * Scripts to test bash completion was inherently flaky as it was
+   affected by whatever random things the user may have on $PATH.
+
+ * A fix was added to the build procedure to work around buggy
+   versions of ccache broke the auto-generation of dependencies, which
+   unfortunately is still relevant because some people use ancient
+   distros.
+
+ * We used to stuff "user@" and then append what we read from
+   /etc/mailname to come up with a default e-mail ident, but a bug
+   lost the "user@" part.
+
+ * "git am" did not parse datestamp correctly from Hg generated patch,
+   when it is run in a locale outside C (or en).
+
+ * Attempt to "branch --edit-description" an existing branch, while
+   being on a detached HEAD, errored out.
+
+ * "git cherry-pick" did not replay a root commit to an unborn branch.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+   killing "git log --show-signature" on a long history.
+
+ * "git rebase --preserve-merges" lost empty merges in recent versions
+   of Git.
+
+ * Rebasing the history of superproject with change in the submodule
+   has been broken since v1.7.12.
+
+ * A failure to push due to non-ff while on an unborn branch
+   dereferenced a NULL pointer when showing an error message.
+
+Also contains various documentation fixes.

+=========================
+
+Fixes since v1.8.1.4
+--------------------
+
+ * Given a string with a multi-byte character that begins with '-' on
+   the command line where an option is expected, the option parser
+   used just one byte of the unknown letter when reporting an error.
+
+ * In v1.8.1, the attribute parser was tightened too restrictive to
+   error out upon seeing an entry that begins with an ! (exclamation),
+   which may confuse users to expect a "negative match", which does
+   not exist.  This has been demoted to a warning; such an entry is
+   still ignored.
+
+ * "git apply --summary" has been taught to make sure the similarity
+   value shown in its output is sensible, even when the input had a
+   bogus value.
+
+ * "git clean" showed what it was going to do, but sometimes ended
+   up finding that it was not allowed to do so, which resulted in a
+   confusing output (e.g. after saying that it will remove an
+   untracked directory, it found an embedded git repository there
+   which it is not allowed to remove).  It now performs the actions
+   and then reports the outcome more faithfully.
+
+ * "git clone" used to allow --bare and --separate-git-dir=$there
+   options at the same time, which was nonsensical.
+
+ * "git cvsimport" mishandled timestamps at DST boundary.
+
+ * We used to have an arbitrary 32 limit for combined diff input,
+   resulting in incorrect number of leading colons shown when showing
+   the "--raw --cc" output.
+
+ * The smart HTTP clients forgot to verify the content-type that comes
+   back from the server side to make sure that the request is being
+   handled properly.
+
+ * "git help remote-helpers" failed to find the documentation.
+
+ * "gitweb" pages served over HTTPS, when configured to show picon or
+   gravatar, referred to these external resources to be fetched via
+   HTTP, resulting in mixed contents warning in browsers.

+Git 1.8.1.6 Release Notes
+=========================
+
+Fixes since v1.8.1.5
+--------------------
+
+ * An earlier change to the attribute system introduced at v1.8.1.2 by
+   mistake stopped a pattern "dir" (without trailing slash) from
+   matching a directory "dir" (it only wanted to allow pattern "dir/"
+   to also match).
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems can get confused upon a
+   hash collision between these pathnames and looped forever.
+
+ * When the "--prefix" option is used to "checkout-index", the code
+   did not pick the correct output filter based on the attribute
+   setting.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+   correctly to the ls-remote and fetch with recent version of Git.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+Also contains various documentation fixes.

+Git v1.8.1 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+In the next major release (not *this* one), we will change the
+behavior of the "git push" command.
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  We will use the "simple" semantics that pushes the
+current branch to the branch with the same name, only when the current
+branch is set to integrate with that remote branch.  There is a user
+preference configuration variable "push.default" to change this, and
+"git push" will warn about the upcoming change until you set this
+variable in this release.
+
+"git branch --set-upstream" is deprecated and may be removed in a
+relatively distant future.  "git branch [-u|--set-upstream-to]" has
+been introduced with a saner order of arguments to replace it.
+
+
+Updates since v1.8.0
+--------------------
+
+UI, Workflows & Features
+
+ * Command-line completion scripts for tcsh and zsh have been added.
+
+ * "git-prompt" scriptlet (in contrib/completion) can be told to paint
+   pieces of the hints in the prompt string in colors.
+
+ * Some documentation pages that used to ship only in the plain text
+   format are now formatted in HTML as well.
+
+ * We used to have a workaround for a bug in ancient "less" that
+   causes it to exit without any output when the terminal is resized.
+   The bug has been fixed in "less" version 406 (June 2007), and the
+   workaround has been removed in this release.
+
+ * When "git checkout" checks out a branch, it tells the user how far
+   behind (or ahead) the new branch is relative to the remote tracking
+   branch it builds upon.  The message now also advises how to sync
+   them up by pushing or pulling.  This can be disabled with the
+   advice.statusHints configuration variable.
+
+ * "git config --get" used to diagnose presence of multiple
+   definitions of the same variable in the same configuration file as
+   an error, but it now applies the "last one wins" rule used by the
+   internal configuration logic.  Strictly speaking, this may be an
+   API regression but it is expected that nobody will notice it in
+   practice.
+
+ * A new configuration variable "diff.context" can be used to
+   give the default number of context lines in the patch output, to
+   override the hardcoded default of 3 lines.
+
+ * "git format-patch" learned the "--notes=<ref>" option to give
+   notes for the commit after the three-dash lines in its output.
+
+ * "git log -p -S<string>" now looks for the <string> after applying
+   the textconv filter (if defined); earlier it inspected the contents
+   of the blobs without filtering.
+
+ * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
+   configuration set to "perl".
+
+ * "git replace -d <object>" now interprets <object> as an extended
+   SHA-1 (e.g. HEAD~4 is allowed), instead of only accepting full hex
+   object name.
+
+ * "git rm $submodule" used to punt on removing a submodule working
+   tree to avoid losing the repository embedded in it.  Because
+   recent git uses a mechanism to separate the submodule repository
+   from the submodule working tree, "git rm" learned to detect this
+   case and removes the submodule working tree when it is safe to do so.
+
+ * "git send-email" used to prompt for the sender address, even when
+   the committer identity is well specified (e.g. via user.name and
+   user.email configuration variables).  The command no longer gives
+   this prompt when not necessary.
+
+ * "git send-email" did not allow non-address garbage strings to
+   appear after addresses on Cc: lines in the patch files (and when
+   told to pick them up to find more recipients), e.g.
+
+     Cc: Stable Kernel <stable@k.org> # for v3.2 and up
+
+   The command now strips " # for v3.2 and up" part before adding the
+   remainder of this line to the list of recipients.
+
+ * "git submodule add" learned to add a new submodule at the same
+   path as the path where an unrelated submodule was bound to in an
+   existing revision via the "--name" option.
+
+ * "git submodule sync" learned the "--recursive" option.
+
+ * "diff.submodule" configuration variable can be used to give custom
+   default value to the "git diff --submodule" option.
+
+ * "git symbolic-ref" learned the "-d $symref" option to delete the
+   named symbolic ref, which is more intuitive way to spell it than
+   "update-ref -d --no-deref $symref".
+
+
+Foreign Interface
+
+ * "git cvsimport" can be told to record timezones (other than GMT)
+   per-author via its author info file.
+
+ * The remote helper interface to interact with subversion
+   repositories (one of the GSoC 2012 projects) has been merged.
+
+ * A new remote-helper interface for Mercurial has been added to
+   contrib/remote-helpers.
+
+ * The documentation for git(1) was pointing at a page at an external
+   site for the list of authors that no longer existed.  The link has
+   been updated to point at an alternative site.
+
+
+Performance, Internal Implementation, etc.
+
+ * Compilation on Cygwin with newer header files are supported now.
+
+ * A couple of low-level implementation updates on MinGW.
+
+ * The logic to generate the initial advertisement from "upload-pack"
+   (i.e. what is invoked by "git fetch" on the other side of the
+   connection) to list what refs are available in the repository has
+   been optimized.
+
+ * The logic to find set of attributes that match a given path has
+   been optimized.
+
+ * Use preloadindex in "git diff-index" and "git update-index", which
+   has a nice speedup on systems with slow stat calls (and even on
+   Linux).
+
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.0
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * The configuration parser had an unnecessary hardcoded limit on
+   variable names that was not checked consistently.
+
+ * The "say" function in the test scaffolding incorrectly allowed
+   "echo" to interpret "\a" as if it were a C-string asking for a
+   BEL output.
+
+ * "git mergetool" feeds /dev/null as a common ancestor when dealing
+   with an add/add conflict, but p4merge backend cannot handle
+   it. Work it around by passing a temporary empty file.
+
+ * "git log -F -E --grep='<ere>'" failed to use the given <ere>
+   pattern as extended regular expression, and instead looked for the
+   string literally.
+
+ * "git grep -e pattern <tree>" asked the attribute system to read
+   "<tree>:.gitattributes" file in the working tree, which was
+   nonsense.
+
+ * A symbolic ref refs/heads/SYM was not correctly removed with "git
+   branch -d SYM"; the command removed the ref pointed by SYM
+   instead.
+
+ * Update "remote tracking branch" in the documentation to
+   "remote-tracking branch".
+
+ * "git pull --rebase" run while the HEAD is detached tried to find
+   the upstream branch of the detached HEAD (which by definition
+   does not exist) and emitted unnecessary error messages.
+
+ * The refs/replace hierarchy was not mentioned in the
+   repository-layout docs.
+
+ * Various rfc2047 quoting issues around a non-ASCII name on the
+   From: line in the output from format-patch have been corrected.
+
+ * Sometimes curl_multi_timeout() function suggested a wrong timeout
+   value when there is no file descriptor to wait on and the http
+   transport ended up sleeping for minutes in select(2) system call.
+   A workaround has been added for this.
+
+ * For a fetch refspec (or the result of applying wildcard on one),
+   we always want the RHS to map to something inside "refs/"
+   hierarchy, but the logic to check it was not exactly right.
+   (merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
+
+ * "git diff -G<pattern>" did not honor textconv filter when looking
+   for changes.
+
+ * Some HTTP servers ask for auth only during the actual packing phase
+   (not in ls-remote phase); this is not really a recommended
+   configuration, but the clients used to fail to authenticate with
+   such servers.
+   (merge 2e736fd jk/maint-http-half-auth-fetch later to maint).
+
+ * "git p4" used to try expanding malformed "$keyword$" that spans
+   across multiple lines.
+
+ * Syntax highlighting in "gitweb" was not quite working.
+
+ * RSS feed from "gitweb" had a xss hole in its title output.
+
+ * "git config --path $key" segfaulted on "[section] key" (a boolean
+   "true" spelled without "=", not "[section] key = true").
+
+ * "git checkout -b foo" while on an unborn branch did not say
+   "Switched to a new branch 'foo'" like other cases.
+
+ * Various codepaths have workaround for a common misconfiguration to
+   spell "UTF-8" as "utf8", but it was not used uniformly.  Most
+   notably, mailinfo (which is used by "git am") lacked this support.
+
+ * We failed to mention a file without any content change but whose
+   permission bit was modified, or (worse yet) a new file without any
+   content in the "git diff --stat" output.
+
+ * When "--stat-count" hides a diffstat for binary contents, the total
+   number of added and removed lines at the bottom was computed
+   incorrectly.
+
+ * When "--stat-count" hides a diffstat for unmerged paths, the total
+   number of affected files at the bottom of the "diff --stat" output
+   was computed incorrectly.
+
+ * "diff --shortstat" miscounted the total number of affected files
+   when there were unmerged paths.
+
+ * "update-ref -d --deref SYM" to delete a ref through a symbolic ref
+   that points to it did not remove it correctly.

+Git v1.8.2.1 Release Notes
+==========================
+
+Fixes since v1.8.2
+------------------
+
+ * An earlier change to the attribute system introduced at v1.8.1.2 by
+   mistake stopped a pattern "dir" (without trailing slash) from
+   matching a directory "dir" (it only wanted to allow pattern "dir/"
+   to also match).
+
+ * Verification of signed tags were not done correctly when not in C
+   or en/US locale.
+
+ * 'git commit -m "$msg"' used to add an extra newline even when
+   $msg already ended with one.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+   "--all" to allow refs that are not annotated tags to be used as a
+   base of description, did not restrict the output from the command
+   to those that match the given pattern.
+
+ * An aliased command spawned from a bare repository that does not say
+   it is bare with "core.bare = yes" is treated as non-bare by mistake.
+
+ * When "format-patch" quoted a non-ascii strings on the header files,
+   it incorrectly applied rfc2047 and chopped a single character in
+   the middle of it.
+
+ * "git archive" reports a failure when asked to create an archive out
+   of an empty tree.  It would be more intuitive to give an empty
+   archive back in such a case.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+   creating a new tag (i.e. not overwriting nor updating).
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+   instead the parser kept reading beyond the end of the string.
+
+ * Annotated tags outside refs/tags/ hierarchy were not advertised
+   correctly to the ls-remote and fetch with recent version of Git.
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems can get confused upon a
+   hash collision between these pathnames and looped forever.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * "git submodule update", when recursed into sub-submodules, did not
+   accumulate the prefix paths.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+   filenames read from the maildir/ in a way that is more likely to
+   sort messages in the order the writing MUA meant to, by sorting
+   numeric segment in numeric order and non-numeric segment in
+   alphabetical order.
+
+ * When export-subst is used, "zip" output recorded incorrect
+   size of the file.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+   most official "UTF-8" when the system does not understand the
+   user-supplied encoding name that are the common alternative
+   spellings of UTF-8.
+
+ * "git branch" did not bother to check nonsense command line
+   parameters and issue errors in many cases.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+   informational message when the translated version of it was too
+   long.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+   command line to "git push" does not say these explicitly.
+
+ * In "git reflog expire", REACHABLE bit was not cleared from the
+   correct objects.
+
+ * The "--color=<when>" argument to the commands in the diff family
+   was described poorly.
+
+ * The arguments given to pre-rebase hook were not documented.
+
+ * The v4 index format was not documented.
+
+ * The "--match=<pattern>" argument "git describe" takes uses glob
+   pattern but it wasn't obvious from the documentation.
+
+ * Some sources failed to compile on systems that lack NI_MAXHOST in
+   their system header (e.g. z/OS).
+
+ * Add an example use of "--env-filter" in "filter-branch"
+   documentation.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+ * In the v1.8.0 era, we changed symbols that do not have to be global
+   to file scope static, but a few functions in graph.c were used by
+   CGit from sideways bypassing the entry points of the API the
+   in-tree users use.
+
+ * "git merge-tree" had a typo in the logic to detect d/f conflicts,
+   which caused it to segfault in some cases.

+Git v1.8.2.2 Release Notes
+==========================
+
+Fixes since v1.8.2.1
+--------------------
+
+ * Zsh completion forgot that '%' character used to signal untracked
+   files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+   crashed some code that trusted that a name, an email and an
+   timestamp can always be found in it.
+
+ * The new core.commentchar configuration was not applied to a few
+   places.
+
+ * "git pull --rebase" did not pass "-v/-q" options to underlying
+   "git rebase".
+
+ * When receive-pack detects error in the pack header it received in
+   order to decide which of unpack-objects or index-pack to run, it
+   returned without closing the error stream, which led to a hang
+   sideband thread.
+
+ * "git diff --diff-algorithm=algo" was understood by the command line
+   parser, but "git diff --diff-algorithm algo" was not.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+   there was no way to disable this.  Make it honor --no-textconv
+   option.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+   "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+   not pay much attention to the annotated tag payload.  Make the code
+   notice the type of the tag object, in addition to the dwim_ref()
+   based classification the current code uses (i.e. the name appears
+   in refs/tags/) to decide when to special case merging of tags.
+
+ * "git cherry-pick" and "git revert" can take more than one commit
+   on the command line these days, but it was not mentioned on the usage
+   text.
+
+ * Perl scripts like "git-svn" closed (not redirecting to /dev/null)
+   the standard error stream, which is not a very smart thing to do.
+   Later open may return file descriptor #2 for unrelated purpose, and
+   error reporting code may write into them.
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+   longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+
+ * "git diff/log --cc" did not work well with options that ignore
+   whitespace changes.
+
+ * Documentation on setting up a http server that requires
+   authentication only on the push but not fetch has been clarified.
+
+ * A few bugfixes to "git rerere" working on corner case merge
+   conflicts have been applied.
+
+ * "git bundle" did not like a bundle created using a commit without
+   any message as its one of the prerequisites.

+   names in error output.
+
+ * When "git difftool" drove "kdiff3", it mistakenly passed --auto

+Git v1.8.2 Release Notes
+========================
+
+Backward compatibility notes (this release)
+-------------------------------------------
+
+"git push $there tag v1.2.3" used to allow replacing a tag v1.2.3
+that already exists in the repository $there, if the rewritten tag
+you are pushing points at a commit that is a descendant of a commit
+that the old tag v1.2.3 points at.  This was found to be error prone
+and starting with this release, any attempt to update an existing
+ref under refs/tags/ hierarchy will fail, without "--force".
+
+When "git add -u" and "git add -A" that does not specify what paths
+to add on the command line is run from inside a subdirectory, the
+scope of the operation has always been limited to the subdirectory.
+Many users found this counter-intuitive, given that "git commit -a"
+and other commands operate on the entire tree regardless of where you
+are.  In this release, these commands give a warning message that
+suggests the users to use "git add -u/-A ." when they want to limit
+the scope to the current directory; doing so will squelch the message,
+while training their fingers.
+
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes the current branch to the branch with the same
+name, only when the current branch is set to integrate with that
+remote branch.  There is a user preference configuration variable
+"push.default" to change this.  If you are an old-timer who is used
+to the "matching" semantics, you can set it to "matching" to keep the
+traditional behaviour.  If you want to live in the future early,
+you can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" and "git add -A", that does not specify what paths
+to add on the command line is run from inside a subdirectory, these
+commands will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands. Because there will be no
+mechanism to make "git add -u" behave as if "git add -u .", it is
+important for those who are used to "git add -u" (without pathspec)
+updating the index only for paths in the current subdirectory to start
+training their fingers to explicitly say "git add -u ." when they mean
+it before Git 2.0 comes.
+
+
+Updates since v1.8.1
+--------------------
+
+UI, Workflows & Features
+
+ * Initial ports to QNX and z/OS UNIX System Services have started.
+
+ * Output from the tests is coloured using "green is okay, yellow is
+   questionable, red is bad and blue is informative" scheme.
+
+ * Mention of "GIT/Git/git" in the documentation have been updated to
+   be more uniform and consistent.  The name of the system and the
+   concept it embodies is "Git"; the command the users type is "git".
+   All-caps "GIT" was merely a way to imitate "Git" typeset in small
+   caps in our ASCII text only documentation and to be avoided.
+
+ * The completion script (in contrib/completion) used to let the
+   default completer to suggest pathnames, which gave too many
+   irrelevant choices (e.g. "git add" would not want to add an
+   unmodified path).  It learnt to use a more git-aware logic to
+   enumerate only relevant ones.
+
+ * In bare repositories, "git shortlog" and other commands now read
+   mailmap files from the tip of the history, to help running these
+   tools in server settings.
+
+ * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the
+   "--format=" option of "git log" and friends can be disabled when
+   the output is not sent to a terminal by prefixing them with
+   "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)".
+
+ * Scripts can ask Git that wildcard patterns in pathspecs they give do
+   not have any significance, i.e. take them as literal strings.
+
+ * The patterns in .gitignore and .gitattributes files can have **/,
+   as a pattern that matches 0 or more levels of subdirectory.
+   E.g. "foo/**/bar" matches "bar" in "foo" itself or in a
+   subdirectory of "foo".
+
+ * When giving arguments without "--" disambiguation, object names
+   that come earlier on the command line must not be interpretable as
+   pathspecs and pathspecs that come later on the command line must
+   not be interpretable as object names.  This disambiguation rule has
+   been tweaked so that ":/" (no other string before or after) is
+   always interpreted as a pathspec; "git cmd -- :/" is no longer
+   needed, you can just say "git cmd :/".
+
+ * Various "hint" lines Git gives when it asks the user to edit
+   messages in the editor are commented out with '#' by default. The
+   core.commentchar configuration variable can be used to customize
+   this '#' to a different character.
+
+ * "git add -u" and "git add -A" without pathspec issues warning to
+   make users aware that they are only operating on paths inside the
+   subdirectory they are in.  Use ":/" (everything from the top) or
+   "." (everything from the $cwd) to disambiguate.
+
+ * "git blame" (and "git diff") learned the "--no-follow" option.
+
+ * "git branch" now rejects some nonsense combinations of command line
+   arguments (e.g. giving more than one branch name to rename) with
+   more case-specific error messages.
+
+ * "git check-ignore" command to help debugging .gitignore files has
+   been added.
+
+ * "git cherry-pick" can be used to replay a root commit to an unborn
+   branch.
+
+ * "git commit" can be told to use --cleanup=whitespace by setting the
+   configuration variable commit.cleanup to 'whitespace'.
+
+ * "git diff" and other Porcelain commands can be told to use a
+   non-standard algorithm by setting diff.algorithm configuration
+   variable.
+
+ * "git fetch --mirror" and fetch that uses other forms of refspec
+   with wildcard used to attempt to update a symbolic ref that match
+   the wildcard on the receiving end, which made little sense (the
+   real ref that is pointed at by the symbolic ref would be updated
+   anyway).  Symbolic refs no longer are affected by such a fetch.
+
+ * "git format-patch" now detects more cases in which a whole branch
+   is being exported, and uses the description for the branch, when
+   asked to write a cover letter for the series.
+
+ * "git format-patch" learned "-v $count" option, and prepends a
+   string "v$count-" to the names of its output files, and also
+   automatically sets the subject prefix to "PATCH v$count". This
+   allows patches from rerolled series to be stored under different
+   names and makes it easier to reuse cover letter messages.
+
+ * "git log" and friends can be told with --use-mailmap option to
+   rewrite the names and email addresses of people using the mailmap
+   mechanism.
+
+ * "git log --cc --graph" now shows the combined diff output with the
+   ancestry graph.
+
+ * "git log --grep=<pattern>" honors i18n.logoutputencoding to look
+   for the pattern after fixing the log message to the specified
+   encoding.
+
+ * "git mergetool" and "git difftool" learned to list the available
+   tool backends in a more consistent manner.
+
+ * "git mergetool" is aware of TortoiseGitMerge now and uses it over
+   TortoiseMerge when available.
+
+ * "git push" now requires "-f" to update a tag, even if it is a
+   fast-forward, as tags are meant to be fixed points.
+
+ * Error messages from "git push" when it stops to prevent remote refs
+   from getting overwritten by mistake have been improved to explain
+   various situations separately.
+
+ * "git push" will stop without doing anything if the new "pre-push"
+   hook exists and exits with a failure.
+
+ * When "git rebase" fails to generate patches to be applied (e.g. due
+   to oom), it failed to detect the failure and instead behaved as if
+   there were nothing to do.  A workaround to use a temporary file has
+   been applied, but we probably would want to revisit this later, as
+   it hurts the common case of not failing at all.
+
+ * Input and preconditions to "git reset" has been loosened where
+   appropriate.  "git reset $fromtree Makefile" requires $fromtree to
+   be any tree (it used to require it to be a commit), for example.
+   "git reset" (without options or parameters) used to error out when
+   you do not have any commits in your history, but it now gives you
+   an empty index (to match non-existent commit you are not even on).
+
+ * "git status" says what branch is being bisected or rebased when
+   able, not just "bisecting" or "rebasing".
+
+ * "git submodule" started learning a new mode to integrate with the
+   tip of the remote branch (as opposed to integrating with the commit
+   recorded in the superproject's gitlink).
+
+ * "git upload-pack" which implements the service "ls-remote" and
+   "fetch" talk to can be told to hide ref hierarchies the server
+   side internally uses (and that clients have no business learning
+   about) with transfer.hiderefs configuration.
+
+
+Foreign Interface
+
+ * "git fast-export" has been updated for its use in the context of
+   the remote helper interface.
+
+ * A new remote helper to interact with bzr has been added to contrib/.
+
+ * "git p4" got various bugfixes around its branch handling.  It is
+   also made usable with Python 2.4/2.5.  In addition, its various
+   portability issues for Cygwin have been addressed.
+
+ * The remote helper to interact with Hg in contrib/ has seen a few
+   fixes.
+
+
+Performance, Internal Implementation, etc.
+
+ * "git fsck" has been taught to be pickier about entries in tree
+   objects that should not be there, e.g. ".", ".git", and "..".
+
+ * Matching paths with common forms of pathspecs that contain wildcard
+   characters has been optimized further.
+
+ * We stopped paying attention to $GIT_CONFIG environment that points
+   at a single configuration file from any command other than "git config"
+   quite a while ago, but "git clone" internally set, exported, and
+   then unexported the variable during its operation unnecessarily.
+
+ * "git reset" internals has been reworked and should be faster in
+   general. We tried to be careful not to break any behaviour but
+   there could be corner cases, especially when running the command
+   from a conflicted state, that we may have missed.
+
+ * The implementation of "imap-send" has been updated to reuse xml
+   quoting code from http-push codepath, and lost a lot of unused
+   code.
+
+ * There is a simple-minded checker for the test scripts in t/
+   directory to catch most common mistakes (it is not enabled by
+   default).
+
+ * You can build with USE_WILDMATCH=YesPlease to use a replacement
+   implementation of pattern matching logic used for pathname-like
+   things, e.g. refnames and paths in the repository.  This new
+   implementation is not expected change the existing behaviour of Git
+   in this release, except for "git for-each-ref" where you can now
+   say "refs/**/master" and match with both refs/heads/master and
+   refs/remotes/origin/master.  We plan to use this new implementation
+   in wider places (e.g. "git ls-files '**/Makefile' may find Makefile
+   at the top-level, and "git log '**/t*.sh'" may find commits that
+   touch a shell script whose name begins with "t" at any level) in
+   future versions of Git, but we are not there yet.  By building with
+   USE_WILDMATCH, using the resulting Git daily and reporting when you
+   find breakages, you can help us get closer to that goal.
+
+ * Some reimplementations of Git do not write all the stat info back
+   to the index due to their implementation limitations (e.g. jgit).
+   A configuration option can tell Git to ignore changes to most of
+   the stat fields and only pay attention to mtime and size, which
+   these implementations can reliably update.  This can be used to
+   avoid excessive revalidation of contents.
+
+ * Some platforms ship with old version of expat where xmlparse.h
+   needs to be included instead of expat.h; the build procedure has
+   been taught about this.
+
+ * "make clean" on platforms that cannot compute header dependencies
+   on the fly did not work with implementations of "rm" that do not
+   like an empty argument list.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.8.1
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.1 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * An element on GIT_CEILING_DIRECTORIES list that does not name the
+   real path to a directory (i.e. a symbolic link) could have caused
+   the GIT_DIR discovery logic to escape the ceiling.
+
+ * When attempting to read the XDG-style $HOME/.config/git/config and
+   finding that $HOME/.config/git is a file, we gave a wrong error
+   message, instead of treating the case as "a custom config file does
+   not exist there" and moving on.
+
+ * The behaviour visible to the end users was confusing, when they
+   attempt to kill a process spawned in the editor that was in turn
+   launched by Git with SIGINT (or SIGQUIT), as Git would catch that
+   signal and die.  We ignore these signals now.
+   (merge 0398fc34 pf/editor-ignore-sigint later to maint).
+
+ * A child process that was killed by a signal (e.g. SIGINT) was
+   reported in an inconsistent way depending on how the process was
+   spawned by us, with or without a shell in between.
+
+ * After failing to create a temporary file using mkstemp(), failing
+   pathname was not reported correctly on some platforms.
+
+ * We used to stuff "user@" and then append what we read from
+   /etc/mailname to come up with a default e-mail ident, but a bug
+   lost the "user@" part.
+
+ * The attribute mechanism didn't allow limiting attributes to be
+   applied to only a single directory itself with "path/" like the
+   exclude mechanism does.  The initial implementation of this that
+   was merged to 'maint' and 1.8.1.2 was with a severe performance
+   degradations and needs to merge a fix-up topic.
+
+ * The smart HTTP clients forgot to verify the content-type that comes
+   back from the server side to make sure that the request is being
+   handled properly.
+
+ * "git am" did not parse datestamp correctly from Hg generated patch,
+   when it is run in a locale outside C (or en).
+
+ * "git apply" misbehaved when fixing whitespace breakages by removing
+   excess trailing blank lines.
+
+ * "git apply --summary" has been taught to make sure the similarity
+   value shown in its output is sensible, even when the input had a
+   bogus value.
+
+ * A tar archive created by "git archive" recorded a directory in a
+   way that made NetBSD's implementation of "tar" sometimes unhappy.
+
+ * "git archive" did not record uncompressed size in the header when
+   streaming a zip archive, which confused some implementations of unzip.
+
+ * "git archive" did not parse configuration values in tar.* namespace
+   correctly.
+   (merge b3873c3 jk/config-parsing-cleanup later to maint).
+
+ * Attempt to "branch --edit-description" an existing branch, while
+   being on a detached HEAD, errored out.
+
+ * "git clean" showed what it was going to do, but sometimes end up
+   finding that it was not allowed to do so, which resulted in a
+   confusing output (e.g. after saying that it will remove an
+   untracked directory, it found an embedded git repository there
+   which it is not allowed to remove).  It now performs the actions
+   and then reports the outcome more faithfully.
+
+ * When "git clone --separate-git-dir=$over_there" is interrupted, it
+   failed to remove the real location of the $GIT_DIR it created.
+   This was most visible when interrupting a submodule update.
+
+ * "git cvsimport" mishandled timestamps at DST boundary.
+
+ * We used to have an arbitrary 32 limit for combined diff input,
+   resulting in incorrect number of leading colons shown when showing
+   the "--raw --cc" output.
+
+ * "git fetch --depth" was broken in at least three ways.  The
+   resulting history was deeper than specified by one commit, it was
+   unclear how to wipe the shallowness of the repository with the
+   command, and documentation was misleading.
+   (merge cfb70e1 nd/fetch-depth-is-broken later to maint).
+
+ * "git log --all -p" that walked refs/notes/textconv/ ref can later
+   try to use the textconv data incorrectly after it gets freed.
+
+ * We forgot to close the file descriptor reading from "gpg" output,
+   killing "git log --show-signature" on a long history.
+
+ * The way "git svn" asked for password using SSH_ASKPASS and
+   GIT_ASKPASS was not in line with the rest of the system.
+
+ * The --graph code fell into infinite loop when asked to do what the
+   code did not expect.
+
+ * http transport was wrong to ask for the username when the
+   authentication is done by certificate identity.
+
+ * "git pack-refs" that ran in parallel to another process that
+   created new refs had a nasty race.
+
+ * Rebasing the history of superproject with change in the submodule
+   has been broken since v1.7.12.
+
+ * After "git add -N" and then writing a tree object out of the
+   index, the cache-tree data structure got corrupted.
+
+ * "git clone" used to allow --bare and --separate-git-dir=$there
+   options at the same time, which was nonsensical.
+
+ * "git rebase --preserve-merges" lost empty merges in recent versions
+   of Git.
+
+ * "git merge --no-edit" computed who were involved in the work done
+   on the side branch, even though that information is to be discarded
+   without getting seen in the editor.
+
+ * "git merge" started calling prepare-commit-msg hook like "git
+   commit" does some time ago, but forgot to pay attention to the exit
+   status of the hook.
+
+ * A failure to push due to non-ff while on an unborn branch
+   dereferenced a NULL pointer when showing an error message.
+
+ * When users spell "cc:" in lowercase in the fake "header" in the
+   trailer part, "git send-email" failed to pick up the addresses from
+   there. As e-mail headers field names are case insensitive, this
+   script should follow suit and treat "cc:" and "Cc:" the same way.
+
+ * Output from "git status --ignored" showed an unexpected interaction
+   with "--untracked".
+
+ * "gitweb", when sorting by age to show repositories with new
+   activities first, used to sort repositories with absolutely
+   nothing in it early, which was not very useful.
+
+ * "gitweb"'s code to sanitize control characters before passing it to
+   "highlight" filter lost known-to-be-safe control characters by
+   mistake.
+
+ * "gitweb" pages served over HTTPS, when configured to show picon or
+   gravatar, referred to these external resources to be fetched via
+   HTTP, resulting in mixed contents warning in browsers.
+
+ * When a line to be wrapped has a solid run of non space characters
+   whose length exactly is the wrap width, "git shortlog -w" failed
+   to add a newline after such a line.
+
+ * Command line completion leaked an unnecessary error message while
+   looking for possible matches with paths in <tree-ish>.
+
+ * Command line completion for "tcsh" emitted an unwanted space
+   after completing a single directory name.
+
+ * Command line completion code was inadvertently made incompatible with
+   older versions of bash by using a newer array notation.
+
+ * "git push" was taught to refuse updating the branch that is
+   currently checked out long time ago, but the user manual was left
+   stale.
+   (merge 50995ed wk/man-deny-current-branch-is-default-these-days later to maint).
+
+ * Some shells do not behave correctly when IFS is unset; work it
+   around by explicitly setting it to the default value.
+
+ * Some scripted programs written in Python did not get updated when
+   PYTHON_PATH changed.
+   (cherry-pick 96a4647fca54031974cd6ad1 later to maint).
+
+ * When autoconf is used, any build on a different commit always ran
+   "config.status --recheck" even when unnecessary.
+
+ * A fix was added to the build procedure to work around buggy
+   versions of ccache broke the auto-generation of dependencies, which
+   unfortunately is still relevant because some people use ancient
+   distros.
+
+ * The autoconf subsystem passed --mandir down to generated
+   config.mak.autogen but forgot to do the same for --htmldir.
+   (merge 55d9bf0 ct/autoconf-htmldir later to maint).
+
+ * A change made on v1.8.1.x maintenance track had a nasty regression
+   to break the build when autoconf is used.
+   (merge 7f1b697 jn/less-reconfigure later to maint).
+
+ * We have been carrying a translated and long-unmaintained copy of an
+   old version of the tutorial; removed.
+
+ * t0050 had tests expecting failures from a bug that was fixed some
+   time ago.
+
+ * t4014, t9502 and t0200 tests had various portability issues that
+   broke on OpenBSD.
+
+ * t9020 and t3600 tests had various portability issues.
+
+ * t9200 runs "cvs init" on a directory that already exists, but a
+   platform can configure this fail for the current user (e.g. you
+   need to be in the cvsadmin group on NetBSD 6.0).
+
+ * t9020 and t9810 had a few non-portable shell script construct.
+
+ * Scripts to test bash completion was inherently flaky as it was
+   affected by whatever random things the user may have on $PATH.
+
+ * An element on GIT_CEILING_DIRECTORIES could be a "logical" pathname
+   that uses a symbolic link to point at somewhere else (e.g. /home/me
+   that points at /net/host/export/home/me, and the latter directory
+   is automounted). Earlier when Git saw such a pathname e.g. /home/me
+   on this environment variable, the "ceiling" mechanism did not take
+   effect. With this release (the fix has also been merged to the
+   v1.8.1.x maintenance series), elements on GIT_CEILING_DIRECTORIES
+   are by default checked for such aliasing coming from symbolic
+   links. As this needs to actually resolve symbolic links for each
+   element on the GIT_CEILING_DIRECTORIES, you can disable this
+   mechanism for some elements by listing them after an empty element
+   on the GIT_CEILING_DIRECTORIES. e.g. Setting /home/me::/home/him to
+   GIT_CEILING_DIRECTORIES makes Git resolve symbolic links in
+   /home/me when checking if the current directory is under /home/me,
+   but does not do so for /home/him.
+   (merge 7ec30aa mh/maint-ceil-absolute later to maint).

+------------------
+
+ * When $HOME is misconfigured to point at an unreadable directory, we

+--------------------
+
+ * Cloning with "git clone --depth N" while fetch.fsckobjects (or
+   transfer.fsckobjects) is set to true did not tell the cut-off
+   points of the shallow history to the process that validates the
+   objects and the history received, causing the validation to fail.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+   not pay attention to the fact that the merge base between A and B
+   was the bottom of the range being specified.
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+   another hunk immediately begins where the earlier one ends.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+   incorrectly when your previous branch was "frotz" (it should be
+   rewritten to "git merge frotz~22" instead).
+
+ * "git commit --allow-empty-message -m ''" should not start an
+   editor.
+
+ * "git push --[no-]verify" was not documented.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+   can take in the HTML documentation was made into a clickable link
+   by mistake.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+   work due to slight differences in array variable notation between
+   these two shells.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+   being rebased when "rebase -i/-m/-p" modes are in use, but not the
+   plain vanilla "rebase".
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+   it was easy to flip it around while push is still going on and push
+   out a branch that the user did not originally intended when the
+   command was started.
+
+ * "difftool --dir-diff" did not copy back changes made by the
+   end-user in the diff tool backend to the working tree in some

+   other than Git, incorrectly.  This is an old breakage in v1.7.11.

+   we updated the auth material after handing it to a call.
+
+ * "git pull" into nothing trashed "local changes" that were in the

+
+ * Many "git submodule" operations did not work on a submodule at a
+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in its error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
+ * "gitweb" forgot to clear a global variable $search_regexp upon each
+   request, mistakenly carrying over the previous search to a new one
+   when used as a persistent CGI.
+
+ * The wildmatch engine did not honor WM_CASEFOLD option correctly.
+
+ * "git log -c --follow $path" segfaulted upon hitting the commit that

+
+ * When a reflog notation is used for implicit "current branch",
+   e.g. "git log @{u}", we did not say which branch and worse said

+
+ * Mac OS X does not like to write(2) more than INT_MAX number of
+   bytes; work it around by chopping write(2) into smaller pieces.
+
+ * Newer MacOS X encourages the programs to compile and link with
+   their CommonCrypto, not with OpenSSL.
+
+Also contains various minor documentation updates.

+Git v1.8.3 Release Notes
+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes only the current branch to the branch with the same
+name, and only when the current branch is set to integrate with that
+remote branch.  Use the user preference configuration variable
+"push.default" to change this.  If you are an old-timer who is used
+to the "matching" semantics, you can set the variable to "matching"
+to keep the traditional behaviour.  If you want to live in the future
+early, you can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+
+Updates since v1.8.2
+--------------------
+
+Foreign interface
+
+ * remote-hg and remote-bzr helpers (in contrib/ since v1.8.2) have
+   been updated; especially, the latter has been done in an
+   accelerated schedule (read: we may not have merged to this release
+   if we were following the usual "cook sufficiently in next before
+   unleashing it to the world" workflow) in order to help Emacs folks,
+   whose primary SCM seems to be stagnating.
+
+
+UI, Workflows & Features
+
+ * A handful of updates applied to gitk, including an addition of
+   "revert" action, showing dates in tags in a nicer way, making
+   colors configurable, and support for -G'pickaxe' search.
+
+ * The prompt string generator (in contrib/completion/) learned to
+   show how many changes there are in total and how many have been
+   replayed during a "git rebase" session.
+
+ * "git branch --vv" learned to paint the name of the branch it
+   integrates with in a different color (color.branch.upstream,
+   which defaults to blue).
+
+ * In a sparsely populated working tree, "git checkout <pathspec>" no
+   longer unmarks paths that match the given pathspec that were
+   originally ignored with "--sparse" (use --ignore-skip-worktree-bits
+   option to resurrect these paths out of the index if you really want
+   to).
+
+ * "git log --format" specifier learned %C(auto) token that tells Git
+   to use color when interpolating %d (decoration), %h (short commit
+   object name), etc. for terminal output.
+
+ * "git bisect" leaves the final outcome as a comment in its bisect
+   log file.
+
+ * "git clone --reference" can now refer to a gitfile "textual symlink"
+   that points at the real location of the repository.
+
+ * "git count-objects" learned "--human-readable" aka "-H" option to
+   show various large numbers in Ki/Mi/GiB scaled as necessary.
+
+ * "git cherry-pick $blob" and "git cherry-pick $tree" are nonsense,
+   and a more readable error message e.g. "can't cherry-pick a tree"
+   is given (we used to say "expected exactly one commit").
+
+ * The "--annotate" option to "git send-email" can be turned on (or
+   off) by default with sendemail.annotate configuration variable (you
+   can use --no-annotate from the command line to override it).
+
+ * The "--cover-letter" option to "git format-patch" can be turned on
+   (or off) by default with format.coverLetter configuration
+   variable. By setting it to 'auto', you can turn it on only for a
+   series with two or more patches.
+
+ * The bash completion support (in contrib/) learned that cherry-pick
+   takes a few more options than it already knew about.
+
+ * "git help" learned "-g" option to show the list of guides just like
+   list of commands are given with "-a".
+
+ * A triangular "pull from one place, push to another place" workflow
+   is supported better by new remote.pushdefault (overrides the
+   "origin" thing) and branch.*.pushremote (overrides the
+   branch.*.remote) configuration variables.
+
+ * "git status" learned to report that you are in the middle of a
+   revert session, just like it does for a cherry-pick and a bisect
+   session.
+
+ * The handling by "git branch --set-upstream-to" against various forms
+   of erroneous inputs was suboptimal and has been improved.
+
+ * When the interactive access to git-shell is not enabled, it issues
+   a message meant to help the system administrator to enable it.  An
+   explicit way has been added to issue custom messages to refuse an
+   access over the network to help the end users who connect to the
+   service expecting an interactive shell.
+
+ * In addition to the case where the user edits the log message with
+   the "e)dit" option of "am -i", replace the "Applying: this patch"
+   message with the final log message contents after applymsg hook
+   munges it.
+
+ * "git status" suggests users to look into using --untracked=no option
+   when it takes too long.
+
+ * "git status" shows a bit more information during a rebase/bisect
+   session.
+
+ * "git fetch" learned to fetch a commit at the tip of an unadvertised
+   ref by specifying a raw object name from the command line when the
+   server side supports this feature.
+
+ * Output from "git log --graph" works better with submodule log
+   output now.
+
+ * "git count-objects -v" learned to report leftover temporary
+   packfiles and other garbage in the object store.
+
+ * A new read-only credential helper (in contrib/) to interact with
+   the .netrc/.authinfo files has been added.
+
+ * "git send-email" can be used with the credential helper system.
+
+ * There was no Porcelain way to say "I no longer am interested in
+   this submodule", once you express your interest in a submodule with
+   "submodule init".  "submodule deinit" is the way to do so.
+
+ * "git pull --rebase" learned to pass "-v/-q" options to underlying
+   "git rebase".
+
+ * The new "--follow-tags" option tells "git push" to push relevant
+   annotated tags when pushing branches out.
+
+ * "git merge" and "git pull" can optionally be told to inspect and
+   reject when merging a commit that does not carry a trusted GPG
+   signature.
+
+ * "git mergetool" now feeds files to the "p4merge" backend in the
+   order that matches the p4 convention, where "theirs" is usually
+   shown on the left side, which is the opposite from what other backends
+   expect.
+
+ * "show/log" now honors gpg.program configuration just like other
+   parts of the code that use GnuPG.
+
+ * "git log" that shows the difference between the parent and the
+   child has been optimized somewhat.
+
+ * "git difftool" allows the user to write into the temporary files
+   being shown; if the user makes changes to the working tree at the
+   same time, it now refrains from overwriting the copy in the working
+   tree and leaves the temporary file so that changes can be merged
+   manually.
+
+ * There was no good way to ask "I have a random string that came from
+   outside world. I want to turn it into a 40-hex object name while
+   making sure such an object exists".  A new peeling suffix ^{object}
+   can be used for that purpose, together with "rev-parse --verify".
+
+
+Performance, Internal Implementation, etc.
+
+ * Updates for building under msvc.
+
+ * A handful of issues in the code that traverses the working tree to find
+   untracked and/or ignored files have been fixed, and the general
+   codepath involved in "status -u" and "clean" have been cleaned up
+   and optimized.
+
+ * The stack footprint of some codepaths that access an object from a
+   pack has been shrunk.
+
+ * The logic to coalesce the same lines removed from the parents in
+   the output from "diff -c/--cc" has been updated, but with O(n^2)
+   complexity, so this might turn out to be undesirable.
+
+ * The code to enforce permission bits on files in $GIT_DIR/ for
+   shared repositories has been simplified.
+
+ * A few codepaths know how much data they need to put in the
+   hashtables they use when they start, but still began with small tables
+   and repeatedly grew and rehashed them.
+
+ * The API to walk reflog entries from the latest to older, which was
+   necessary for operations such as "git checkout -", was cumbersome
+   to use correctly and also inefficient.
+
+ * Codepaths that inspect log-message-to-be and decide when to add a
+   new Signed-off-by line in various commands have been consolidated.
+
+ * The pkt-line API, implementation and its callers have been cleaned
+   up to make them more robust.
+
+ * The Cygwin port has a faster-but-lying lstat(2) emulation whose
+   incorrectness does not matter in practice except for a few
+   codepaths, and setting permission bits on directories is a codepath
+   that needs to use a more correct one.
+
+ * "git checkout" had repeated pathspec matches on the same paths,
+   which have been consolidated.  Also a bug in "git checkout dir/"
+   that is started from an unmerged index has been fixed.
+
+ * A few bugfixes to "git rerere" working on corner case merge
+   conflicts have been applied.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.2
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.2 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * Recent versions of File::Temp (used by "git svn") started blowing
+   up when its tempfile sub is called as a class method; updated the
+   callsite to call it as a plain vanilla function to fix it.
+   (merge eafc2dd hb/git-pm-tempfile later to maint).
+
+ * Various subcommands of "git remote" simply ignored extraneous
+   command line arguments instead of diagnosing them as errors.
+
+ * When receive-pack detects an error in the pack header it received in
+   order to decide which of unpack-objects or index-pack to run, it
+   returned without closing the error stream, which led to a hung
+   sideband thread.
+
+ * Zsh completion forgot that the '%' character used to signal untracked
+   files needs to be escaped with another '%'.
+
+ * A commit object whose author or committer ident are malformed
+   crashed some code that trusted that a name, an email and a
+   timestamp can always be found in it.
+
+ * When "upload-pack" fails while generating a pack in response to
+   "git fetch" (or "git clone"), the receiving side had
+   a programming error that triggered the die handler
+   recursively.
+
+ * "rev-list --stdin" and friends kept bogus pointers into the input
+   buffer around as human readable object names.  This was not a huge
+   problem but was exposed by a new change that uses these names in
+   error output.
+
+ * Smart-capable HTTP servers were not restricted via the
+   GIT_NAMESPACE mechanism when talking with commit-walking clients,
+   like they are when talking with smart HTTP clients.
+   (merge 6130f86 jk/http-dumb-namespaces later to maint).
+
+ * "git merge-tree" did not omit a merge result that is identical to
+   the "our" side in certain cases.
+   (merge aacecc3 jk/merge-tree-added-identically later to maint).
+
+ * Perl scripts like "git-svn" closed (instead of redirecting to /dev/null)
+   the standard error stream, which is not a very smart thing to do.
+   A later open may return file descriptor #2 for an unrelated purpose, and
+   error reporting code may write into it.
+
+ * "git show-branch" was not prepared to show a very long run of
+   ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.
+
+ * "git diff --diff-algorithm algo" is also understood as "git diff
+   --diff-algorithm=algo".
+
+ * The new core.commentchar configuration was not applied in a few
+   places.
+
+ * "git bundle" erroneously bailed out when parsing a valid bundle
+   containing a prerequisite commit without a commit message.
+
+ * "git log -S/-G" started paying attention to textconv filter, but
+   there was no way to disable this.  Make it honor the --no-textconv
+   option.
+
+ * When used with the "-d temporary-directory" option, "git filter-branch"
+   failed to come back to the original working tree to perform the
+   final clean-up procedure.
+
+ * "git merge $(git rev-parse v1.8.2)" behaved quite differently from
+   "git merge v1.8.2", as if v1.8.2 were written as v1.8.2^0 and did
+   not pay much attention to the annotated tag payload.  Make the code
+   notice the type of the tag object, in addition to the dwim_ref()
+   based classification the current code uses (i.e. the name appears
+   in refs/tags/) to decide when to special-case tag merging.
+
+ * Fix a 1.8.1.x regression that stopped matching "dir" (without a
+   trailing slash) to a directory "dir".
+
+ * "git apply --whitespace=fix" was not prepared to see a line getting
+   longer after fixing whitespaces (e.g. tab-in-indent aka Python).
+
+ * The prompt string generator (in contrib/completion/) did not notice
+   when we are in a middle of a "git revert" session.
+
+ * "submodule summary --summary-limit" option did not support the
+   "--option=value" form.
+
+ * "index-pack --fix-thin" used an uninitialized value to compute
+   the delta depths of objects it appends to the resulting pack.
+
+ * "index-pack --verify-stat" used a few counters outside the protection
+   of a mutex, possibly showing incorrect numbers.
+
+ * The code to keep track of what directory names are known to Git on
+   platforms with case insensitive filesystems could get confused upon a
+   hash collision between these pathnames and would loop forever.
+
+ * Annotated tags outside the refs/tags/ hierarchy were not advertised
+   correctly to ls-remote and fetch with recent versions of Git.
+
+ * Recent optimizations broke shallow clones.
+
+ * "git cmd -- ':(top'" was not diagnosed as an invalid syntax, and
+   instead the parser kept reading beyond the end of the string.
+
+ * "git tag -f <tag>" always said "Updated tag '<tag>'" even when
+   creating a new tag (i.e. neither overwriting nor updating).
+
+ * "git p4" did not behave well when the path to the root of the P4
+   client was not its real path.
+   (merge bbd8486 pw/p4-symlinked-root later to maint).
+
+ * "git archive" reported a failure when asked to create an archive out
+   of an empty tree.  It is more intuitive to give an empty
+   archive back in such a case.
+
+ * When "format-patch" quoted a non-ascii string in header files,
+   it incorrectly applied rfc2047 and chopped a single character in
+   the middle of the string.
+
+ * An aliased command spawned from a bare repository that does not say
+   it is bare with "core.bare = yes" was treated as non-bare by mistake.
+
+ * In "git reflog expire", the REACHABLE bit was not cleared from the
+   correct objects.
+
+ * The logic used by "git diff -M --stat" to shorten the names of
+   files before and after a rename did not work correctly when the
+   common prefix and suffix between the two filenames overlapped.
+
+ * The "--match=<pattern>" option of "git describe", when used with
+   "--all" to allow refs that are not annotated tags to be a
+   base of description, did not restrict the output from the command
+   to those refs that match the given pattern.
+
+ * Clarify in the documentation "what" gets pushed to "where" when the
+   command line to "git push" does not say these explicitly.
+
+ * The "--color=<when>" argument to the commands in the diff family
+   was described poorly.
+
+ * The arguments given to the pre-rebase hook were not documented.
+
+ * The v4 index format was not documented.
+
+ * The "--match=<pattern>" argument "git describe" takes uses glob
+   pattern but it wasn't obvious from the documentation.
+
+ * Some sources failed to compile on systems that lack NI_MAXHOST in
+   their system header (e.g. z/OS).
+
+ * Add an example use of "--env-filter" in "filter-branch"
+   documentation.
+
+ * "git bundle verify" did not say "records a complete history" for a
+   bundle that does not have any prerequisites.
+
+ * In the v1.8.0 era, we changed symbols that do not have to be global
+   to file scope static, but a few functions in graph.c were used by
+   CGit sideways, bypassing the entry points of the API the
+   in-tree users use.
+
+ * "git update-index -h" did not do the usual "-h(elp)" thing.
+
+ * "git index-pack" had a buffer-overflow while preparing an
+   informational message when the translated version of it was too
+   long.
+
+ * 'git commit -m "$msg"' used to add an extra newline even when
+   $msg already ended with one.
+
+ * The SSL peer verification done by "git imap-send" did not ask for
+   Server Name Indication (RFC 4366), failing to connect to SSL/TLS
+   sites that serve multiple hostnames on a single IP.
+
+ * perl/Git.pm::cat_blob slurped everything in core only to write it
+   out to a file descriptor, which was not a very smart thing to do.
+
+ * "git branch" did not bother to check nonsense command line
+   parameters.  It now issues errors in many cases.
+
+ * Verification of signed tags was not done correctly when not in C
+   or en/US locale.
+
+ * Some platforms and users spell UTF-8 differently; retry with the
+   most official "UTF-8" when the system does not understand the
+   user-supplied encoding name that is a common alternative
+   spelling of UTF-8.
+
+ * When export-subst is used, "zip" output recorded an incorrect
+   size of the file.
+
+ * "git am $maildir/" applied messages in an unexpected order; sort
+   filenames read from the maildir/ in a way that is more likely to
+   sort the messages in the order the writing MUA meant to, by sorting
+   numeric segments in numeric order and non-numeric segments in
+   alphabetical order.
+
+ * "git submodule update", when recursed into sub-submodules, did not
+   accumulate the prefix paths.

+Git v1.8.4.1 Release Notes
+========================
+
+Fixes since v1.8.4
+------------------
+
+ * Some old versions of bash do not grok some constructs like
+   'printf -v varname' which the prompt and completion code started
+   to use recently.  The completion and prompt scripts have been
+   adjusted to work better with these old versions of bash.
+
+ * In FreeBSD's and NetBSD's "sh", a return in a dot script in a
+   function returns from the function, not only in the dot script,
+   breaking "git rebase" on these platforms (regression introduced
+   in 1.8.4-rc1).
+
+ * "git rebase -i" and other scripted commands were feeding a
+   random, data dependant error message to 'echo' and expecting it
+   to come out literally.
+
+ * Setting the "submodule.<name>.path" variable to the empty
+   "true" caused the configuration parser to segfault.
+
+ * Output from "git log --full-diff -- <pathspec>" looked strange
+   because comparison was done with the previous ancestor that
+   touched the specified <pathspec>, causing the patches for paths
+   outside the pathspec to show more than the single commit has
+   changed.
+
+ * The auto-tag-following code in "git fetch" tries to reuse the
+   same transport twice when the serving end does not cooperate and
+   does not give tags that point to commits that are asked for as
+   part of the primary transfer.  Unfortunately, Git-aware transport
+   helper interface is not designed to be used more than once, hence
+   this did not work over smart-http transfer.  Fixed.
+
+ * Send a large request to read(2)/write(2) as a smaller but still
+   reasonably large chunks, which would improve the latency when the
+   operation needs to be killed and incidentally works around broken
+   64-bit systems that cannot take a 2GB write or read in one go.
+
+ * A ".mailmap" file that ends with an incomplete line, when read
+   from a blob, was not handled properly.
+
+ * The recent "short-cut clone connectivity check" topic broke a
+   shallow repository when a fetch operation tries to auto-follow
+   tags.
+
+ * When send-email comes up with an error message to die with upon
+   failure to start an SSL session, it tried to read the error
+   string from a wrong place.
+
+ * A call to xread() was used without a loop to cope with short
+   read in the codepath to stream large blobs to a pack.
+
+ * On platforms with fgetc() and friends defined as macros, the
+   configuration parser did not compile.
+
+ * New versions of MediaWiki introduced a new API for returning
+   more than 500 results in response to a query, which would cause
+   the MediaWiki remote helper to go into an infinite loop.
+
+ * Subversion's serf access method (the only one available in
+   Subversion 1.8) for http and https URLs in skelta mode tells its
+   caller to open multiple files at a time, which made "git svn
+   fetch" complain that "Temp file with moniker 'svn_delta' already
+   in use" instead of fetching.
+
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4.2 Release Notes
+========================
+
+Fixes since v1.8.4.1
+--------------------
+
+ * "git clone" gave some progress messages to the standard output, not
+   to the standard error, and did not allow suppressing them with the
+   "--no-progress" option.
+
+ * "format-patch --from=<whom>" forgot to omit unnecessary in-body
+   from line, i.e. when <whom> is the same as the real author.
+
+ * "git shortlog" used to choke and die when there is a malformed
+   commit (e.g. missing authors); it now simply ignore such a commit
+   and keeps going.
+
+ * "git merge-recursive" did not parse its "--diff-algorithm=" command
+   line option correctly.
+
+ * "git branch --track" had a minor regression in v1.8.3.2 and later
+   that made it impossible to base your local work on anything but a
+   local branch of the upstream repository you are tracking from.
+
+ * "git ls-files -k" needs to crawl only the part of the working tree
+   that may overlap the paths in the index to find killed files, but
+   shared code with the logic to find all the untracked files, which
+   made it unnecessarily inefficient.
+
+ * When there is no sufficient overlap between old and new history
+   during a "git fetch" into a shallow repository, objects that the
+   sending side knows the receiving end has were unnecessarily sent.
+
+ * When running "fetch -q", a long silence while the sender side
+   computes the set of objects to send can be mistaken by proxies as
+   dropped connection.  The server side has been taught to send a
+   small empty messages to keep the connection alive.
+
+ * When the webserver responds with "405 Method Not Allowed", "git
+   http-backend" should tell the client what methods are allowed with
+   the "Allow" header.
+
+ * "git cvsserver" computed the permission mode bits incorrectly for
+   executable files.
+
+ * The implementation of "add -i" has a crippling code to work around
+   ActiveState Perl limitation but it by mistake also triggered on Git
+   for Windows where MSYS perl is used.
+
+ * We made sure that we notice the user-supplied GIT_DIR is actually a
+   gitfile, but did not do the same when the default ".git" is a
+   gitfile.
+
+ * When an object is not found after checking the packfiles and then
+   loose object directory, read_sha1_file() re-checks the packfiles to
+   prevent racing with a concurrent repacker; teach the same logic to
+   has_sha1_file().
+
+ * "git commit --author=$name", when $name is not in the canonical
+   "A. U. Thor <au.thor@example.xz>" format, looks for a matching name
+   from existing history, but did not consult mailmap to grab the
+   preferred author name.
+
+ * The commit object names in the insn sheet that was prepared at the
+   beginning of "rebase -i" session can become ambiguous as the
+   rebasing progresses and the repository gains more commits. Make
+   sure the internal record is kept with full 40-hex object names.
+
+ * "git rebase --preserve-merges" internally used the merge machinery
+   and as a side effect, left merge summary message in the log, but
+   when rebasing, there should not be a need for merge summary.
+
+ * "git rebase -i" forgot that the comment character can be
+   configurable while reading its insn sheet.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4.3 Release Notes
+========================
+
+Fixes since v1.8.4.2
+--------------------
+
+ * The interaction between use of Perl in our test suite and NO_PERL
+   has been clarified a bit.
+
+ * A fast-import stream expresses a pathname with funny characters by
+   quoting them in C style; remote-hg remote helper (in contrib/)
+   forgot to unquote such a path.
+
+ * One long-standing flaw in the pack transfer protocol used by "git
+   clone" was that there was no way to tell the other end which branch
+   "HEAD" points at, and the receiving end needed to guess.  A new
+   capability has been defined in the pack protocol to convey this
+   information so that cloning from a repository with more than one
+   branches pointing at the same commit where the HEAD is at now
+   reliably sets the initial branch in the resulting repository.
+
+ * We did not handle cases where http transport gets redirected during
+   the authorization request (e.g. from http:// to https://).
+
+ * "git rev-list --objects ^v1.0^ v1.0" gave v1.0 tag itself in the
+   output, but "git rev-list --objects v1.0^..v1.0" did not.
+
+ * The fall-back parsing of commit objects with broken author or
+   committer lines were less robust than ideal in picking up the
+   timestamps.
+
+ * Bash prompting code to deal with an SVN remote as an upstream
+   were coded in a way not supported by older Bash versions (3.x).
+
+ * "git checkout topic", when there is not yet a local "topic" branch
+   but there is a unique remote-tracking branch for a remote "topic"
+   branch, pretended as if "git checkout -t -b topic remote/$r/topic"
+   (for that unique remote $r) was run. This hack however was not
+   implemented for "git checkout topic --".
+
+ * Coloring around octopus merges in "log --graph" output was screwy.
+
+ * We did not generate HTML version of documentation to "git subtree"
+   in contrib/.
+
+ * The synopsis section of "git unpack-objects" documentation has been
+   clarified a bit.
+
+ * An ancient How-To on serving Git repositories on an HTTP server
+   lacked a warning that it has been mostly superseded with more
+   modern way.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.

+Git v1.8.4.4 Release Notes
+========================
+

+--------------------
+
+ * The fix in v1.8.4.3 to the pack transfer protocol to propagate
+   the target of symbolic refs broke "git clone/git fetch" from a

+==========================
+
+Fixes since v1.8.4.4
+--------------------
+
+ * Recent update to remote-hg that attempted to make it work better

+Git v1.8.4 Release Notes
+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics that pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+
+Updates since v1.8.3
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * Cygwin port has been updated for more recent Cygwin 1.7.
+
+ * "git rebase -i" now honors --strategy and -X options.
+
+ * Git-gui has been updated to its 0.18.0 version.
+
+ * MediaWiki remote helper (in contrib/) has been updated to use the
+   credential helper interface from Git.pm.
+
+ * Update build for Cygwin 1.[57].  Torsten Bögershausen reports that
+   this is fine with Cygwin 1.7 ($gmane/225824) so let's try moving it
+   ahead.
+
+ * The credential helper to talk to keychain on OS X (in contrib/) has
+   been updated to kick in not just when talking http/https but also
+   imap(s) and smtp.
+
+ * Remote transport helper has been updated to report errors and
+   maintain ref hierarchy used to keep track of its own state better.
+
+ * With "export" remote-helper protocol, (1) a push that tries to
+   update a remote ref whose name is different from the pushing side
+   does not work yet, and (2) the helper may not know how to do
+   --dry-run; these problematic cases are disabled for now.
+
+ * git-remote-hg/bzr (in contrib/) updates.
+
+ * git-remote-mw (in contrib/) hints users to check the certificate,
+   when https:// connection failed.
+
+ * git-remote-mw (in contrib/) adds a command to allow previewing the
+   contents locally before pushing it out, when working with a
+   MediaWiki remote.
+
+
+UI, Workflows & Features
+
+ * Sample "post-receive-email" hook script got an enhanced replacement
+   "multimail" (in contrib/).
+
+ * Also in contrib/ is a new "contacts" script that runs "git blame"
+   to find out the people who may be interested in a set of changes.
+
+ * "git clean" command learned an interactive mode.
+
+ * The "--head" option to "git show-ref" was only to add "HEAD" to the
+   list of candidate refs to be filtered by the usual rules
+   (e.g. "--heads" that only show refs under refs/heads).  The meaning
+   of the option has been changed to always show "HEAD" regardless of
+   what filtering will be applied to any other ref.
+
+   This is a backward incompatible change and might cause breakages to
+   people's existing scripts.
+
+ * "git show -s" was less discoverable than it should have been.  It
+   now has a natural synonym "git show --no-patch".
+
+ * "git check-mailmap" is a new command that lets you map usernames
+   and e-mail addresses through the mailmap mechanism, just like many
+   built-in commands do.
+
+ * "git name-rev" learned to name an annotated tag object back to its
+   tagname; "git name-rev $(git rev-parse v1.0.0)" gives "tags/v1.0.0",
+   for example.
+
+ * "git cat-file --batch-check=<format>" is added, primarily to allow
+   on-disk footprint of objects in packfiles (often they are a lot
+   smaller than their true size, when expressed as deltas) to be
+   reported.
+
+ * "git rebase [-i]" used to leave just "rebase" as its reflog messages
+   for some operations. They have been reworded to be more informative.
+
+ * In addition to the choice from "rebase, merge, or checkout-detach",
+   "submodule update" can allow a custom command to be used in to
+   update the working tree of submodules via the "submodule.*.update"
+   configuration variable.
+
+ * "git submodule update" can optionally clone the submodule
+   repositories shallowly.
+
+ * "git format-patch" learned "--from[=whom]" option, which sets the
+   "From: " header to the specified person (or the person who runs the
+   command, if "=whom" part is missing) and move the original author
+   information to an in-body From: header as necessary.
+
+ * The configuration variable "merge.ff" was cleary a tri-state to
+   choose one from "favor fast-forward when possible", "always create
+   a merge even when the history could fast-forward" and "do not
+   create any merge, only update when the history fast-forwards", but
+   the command line parser did not implement the usual convention of
+   "last one wins, and command line overrides the configuration"
+   correctly.
+
+ * "gitweb" learned to optionally place extra links that point at the
+   levels higher than the Gitweb pages themselves in the breadcrumbs,
+   so that it can be used as part of a larger installation.
+
+ * "git log --format=" now honors i18n.logoutputencoding configuration
+   variable.
+
+ * The "push.default=simple" mode of "git push" has been updated to
+   behave like "current" without requiring a remote tracking
+   information, when you push to a remote that is different from where
+   you fetch from (i.e. a triangular workflow).
+
+ * Having multiple "fixup!" on a line in the rebase instruction sheet
+   did not work very well with "git rebase -i --autosquash".
+
+ * "git log" learned the "--author-date-order" option, with which the
+   output is topologically sorted and commits in parallel histories
+   are shown intermixed together based on the author timestamp.
+
+ * Various subcommands of "git submodule" refused to run from anywhere
+   other than the top of the working tree of the superproject, but
+   they have been taught to let you run from a subdirectory.
+
+ * "git diff" learned a mode that ignores hunks whose change consists
+   only of additions and removals of blank lines, which is the same as
+   "diff -B" (ignore blank lines) of GNU diff.
+
+ * "git rm" gives a single message followed by list of paths to report
+   multiple paths that cannot be removed.
+
+ * "git rebase" can be told with ":/look for this string" syntax commits
+   to replay the changes onto and where the work to be replayed begins.
+
+ * Many tutorials teach users to set "color.ui" to "auto" as the first
+   thing after you set "user.name/email" to introduce yourselves to
+   Git.  Now the variable defaults to "auto".
+
+ * On Cygwin, "cygstart" is now recognised as a possible way to start
+   a web browser (used in "help -w" and "instaweb" among others).
+
+ * "git status" learned status.branch and status.short configuration
+   variables to use --branch and --short options by default (override
+   with --no-branch and --no-short options from the command line).
+
+ * "git cmd <name>", when <name> happens to be a 40-hex string,
+   directly uses the 40-hex string as an object name, even if a ref
+   "refs/<some hierarchy>/<name>" exists.  This disambiguation order
+   is unlikely to change, but we should warn about the ambiguity just
+   like we warn when more than one refs/ hierarchies share the same
+   name.
+
+ * "git rebase" learned "--[no-]autostash" option to save local
+   changes instead of refusing to run (to which people's normal
+   response was to stash them and re-run).  This introduced a corner
+   case breakage to "git am --abort" but it has been fixed.
+
+ * "check-ignore" (new feature since 1.8.2) has been updated to work
+   more like "check-attr" over bidi-pipes.
+
+ * "git describe" learned "--first-parent" option to limit its closest
+   tagged commit search to the first-parent chain.
+
+ * "git merge foo" that might have meant "git merge origin/foo" is
+   diagnosed with a more informative error message.
+
+ * "git log -L<line>,<range>:<filename>" has been added.  This may
+   still have leaks and rough edges, though.
+
+ * We used the approxidate() parser for "--expire=<timestamp>" options
+   of various commands, but it is better to treat --expire=all and
+   --expire=now a bit more specially than using the current timestamp.
+   "git gc" and "git reflog" have been updated with a new parsing
+   function for expiry dates.
+
+ * Updates to completion (both bash and zsh) helpers.
+
+ * The behaviour of the "--chain-reply-to" option of "git send-email"
+   have changed at 1.7.0, and we added a warning/advice message to
+   help users adjust to the new behaviour back then, but we kept it
+   around for too long.  The message has finally been removed.
+
+ * "git fetch origin master" unlike "git fetch origin" or "git fetch"
+   did not update "refs/remotes/origin/master"; this was an early
+   design decision to keep the update of remote tracking branches
+   predictable, but in practice it turns out that people find it more
+   convenient to opportunistically update them whenever we have a
+   chance, and we have been updating them when we run "git push" which
+   already breaks the original "predictability" anyway.
+
+ * The configuration variable core.checkstat was advertised in the
+   documentation but the code expected core.statinfo instead.
+   For now, we accept both core.checkstat and core.statinfo, but the
+   latter will be removed in the longer term.
+
+
+Performance, Internal Implementation, etc.
+
+ * On Cygwin, we used to use our own lstat(2) emulation that is
+   allegedly faster than the platform one in codepaths where some of
+   the information it returns did not matter, but it started to bite
+   us in a few codepaths where the trick it uses to cheat does show
+   breakages. This emulation has been removed and we use the native
+   lstat(2) emulation supplied by Cygwin now.
+
+ * The function attributes extensions are used to catch mistakes in
+   use of our own variadic functions that use NULL sentinel at the end
+   (i.e. like execl(3)) and format strings (i.e. like printf(3)).
+
+ * The code to allow configuration data to be read from in-tree blob
+   objects is in.  This may help working in a bare repository and
+   submodule updates.
+
+ * Fetching between repositories with many refs employed O(n^2)
+   algorithm to match up the common objects, which has been corrected.
+
+ * The original way to specify remote repository using .git/branches/
+   used to have a nifty feature.  The code to support the feature was
+   still in a function but the caller was changed not to call it 5
+   years ago, breaking that feature and leaving the supporting code
+   unreachable.  The dead code has been removed.
+
+ * "git pack-refs" that races with new ref creation or deletion have
+   been susceptible to lossage of refs under right conditions, which
+   has been tightened up.
+
+ * We read loose and packed references in two steps, but after
+   deciding to read a loose ref but before actually opening it to read
+   it, another process racing with us can unlink it, which would cause
+   us to barf.  The codepath has been updated to retry when such a
+   race is detected, instead of outright failing.
+
+ * Uses of the platform fnmatch(3) function (many places in the code,
+   matching pathspec, .gitignore and .gitattributes to name a few)
+   have been replaced with wildmatch, allowing "foo/**/bar" that would
+   match foo/bar, foo/a/bar, foo/a/b/bar, etc.
+
+ * Memory ownership and lifetime rules for what for-each-ref feeds to
+   its callbacks have been clarified (in short, "you do not own it, so
+   make a copy if you want to keep it").
+
+ * The revision traversal logic to improve culling of irrelevant
+   parents while traversing a mergy history has been updated.
+
+ * Some leaks in unpack-trees (used in merge, cherry-pick and other
+   codepaths) have been plugged.
+
+ * The codepath to read from marks files in fast-import/export did not
+   have to accept anything but 40-hex representation of the object
+   name.  Further, fast-export did not need full in-core object
+   representation to have parsed wen reading from them.  These
+   codepaths have been optimized by taking advantage of these access
+   patterns.
+
+ * Object lookup logic, when the object hashtable starts to become
+   crowded, has been optimized.
+
+ * When TEST_OUTPUT_DIRECTORY setting is used, it was handled somewhat
+   inconsistently between the test framework and t/Makefile, and logic
+   to summarize the results looked at a wrong place.
+
+ * "git clone" uses a lighter-weight implementation when making sure
+   that the history behind refs are complete.
+
+ * Many warnings from sparse source checker in compat/ area has been
+   squelched.
+
+ * The code to reading and updating packed-refs file has been updated,
+   correcting corner case bugs.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.3
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.3 in the maintenance
+track are contained in this release (see release notes to them for
+details).
+
+ * Newer Net::SMTP::SSL module does not want the user programs to use
+   the default behaviour to let server certificate go without
+   verification, so by default enable the verification with a
+   mechanism to turn it off if needed.
+   (merge 35035bb rr/send-email-ssl-verify later to maint).
+
+ * When "git" is spawned in such a way that any of the low 3 file
+   descriptors is closed, our first open() may yield file descriptor 2,
+   and writing error message to it would screw things up in a big way.
+   (merge a11c396 tr/protect-low-3-fds later to maint).
+
+ * The mailmap mechanism unnecessarily downcased the e-mail addresses
+   in the output, and also ignored the human name when it is a single
+   character name.
+   (merge bd23794 jc/mailmap-case-insensitivity later to maint).
+
+ * In two places we did not check return value (expected to be a file
+   descriptor) correctly.
+   (merge a77f106 tr/fd-gotcha-fixes later to maint).
+
+ * Logic to auto-detect character encodings in the commit log message
+   did not reject overlong and invalid UTF-8 characters.
+   (merge 81050ac bc/commit-invalid-utf8 later to maint).
+
+ * Pass port number as a separate argument when "send-email" initializes
+   Net::SMTP, instead of as a part of the hostname, i.e. host:port.
+   This allows GSSAPI codepath to match with the hostname given.
+   (merge 1a741bf bc/send-email-use-port-as-separate-param later to maint).
+
+ * "git diff" refused to even show difference when core.safecrlf is
+   set to true (i.e. error out) and there are offending lines in the
+   working tree files.
+   (merge 5430bb2 jc/maint-diff-core-safecrlf later to maint).
+
+ * A test that should have failed but didn't revealed a bug that needs
+   to be corrected.
+   (merge 94d75d1 jc/t1512-fix later to maint).
+
+ * An overlong path to a .git directory may have overflown the
+   temporary path buffer used to create a name for lockfiles.
+   (merge 2fbd4f9 mh/maint-lockfile-overflow later to maint).
+
+ * Invocations of "git checkout" used internally by "git rebase" were
+   counted as "checkout", and affected later "git checkout -" to the
+   the user to an unexpected place.
+   (merge 3bed291 rr/rebase-checkout-reflog later to maint).
+
+ * The configuration variable column.ui was poorly documented.
+   (merge 5e62cc1 rr/column-doc later to maint).
+
+ * "git name-rev --refs=tags/v*" were forbidden, which was a bit
+   inconvenient (you had to give a pattern to match refs fully, like
+   --refs=refs/tags/v*).
+   (merge 98c5c4a nk/name-rev-abbreviated-refs later to maint).
+
+ * "git apply" parsed patches that add new files, generated by
+   programs other than Git, incorrectly.  This is an old breakage in
+   v1.7.11 and will need to be merged down to the maintenance tracks.
+
+ * Older cURL wanted piece of memory we call it with to be stable, but
+   we updated the auth material after handing it to a call.
+
+ * "git pull" into nothing trashed "local changes" that were in the
+   index, and this avoids it.
+
+ * Many "git submodule" operations do not work on a submodule at a
+   path whose name is not in ASCII.
+
+ * "cherry-pick" had a small leak in an error codepath.
+
+ * Logic used by git-send-email to suppress cc mishandled names like
+   "A U. Thor" <author@example.xz>, where the human readable part
+   needs to be quoted (the user input may not have the double quotes
+   around the name, and comparison was done between quoted and
+   unquoted strings).  It also mishandled names that need RFC2047
+   quoting.
+
+ * Call to discard_cache/discard_index (used when we use different
+   contents of the index in-core, in many operations like commit,
+   apply, and merge) used to leak memory that held the array of index
+   entries, which has been plugged.
+   (merge a0fc4db rs/discard-index-discard-array later to maint).
+
+ * "gitweb" forgot to clear a global variable $search_regexp upon each
+   request, mistakenly carrying over the previous search to a new one
+   when used as a persistent CGI.
+
+ * The wildmatch engine did not honor WM_CASEFOLD option correctly.
+
+ * "git log -c --follow $path" segfaulted upon hitting the commit that
+   renamed the $path being followed.
+
+ * When a reflog notation is used for implicit "current branch", we
+   did not say which branch and worse said "branch ''".
+
+ * "difftool --dir-diff" did not copy back changes made by the
+   end-user in the diff tool backend to the working tree in some
+   cases.
+
+ * "git push $there HEAD:branch" did not resolve HEAD early enough, so
+   it was easy to flip it around while push is still going on and push
+   out a branch that the user did not originally intended when the
+   command was started.
+
+ * The bash prompt code (in contrib/) displayed the name of the branch
+   being rebased when "rebase -i/-m/-p" modes are in use, but not the
+   plain vanilla "rebase".
+
+ * Handling of negative exclude pattern for directories "!dir" was
+   broken in the update to v1.8.3.
+
+ * zsh prompt script that borrowed from bash prompt script did not
+   work due to slight differences in array variable notation between
+   these two shells.
+
+ * An entry for "file://" scheme in the enumeration of URL types Git
+   can take in the HTML documentation was made into a clickable link
+   by mistake.
+
+ * "git push --[no-]verify" was not documented.
+
+ * Stop installing the git-remote-testpy script that is only used for
+   testing.
+
+ * "git commit --allow-empty-message -m ''" should not start an
+   editor.
+
+ * "git merge @{-1}~22" was rewritten to "git merge frotz@{1}~22"
+   incorrectly when your previous branch was "frotz" (it should be
+   rewritten to "git merge frotz~22" instead).
+
+ * "git diff -c -p" was not showing a deleted line from a hunk when
+   another hunk immediately begins where the earlier one ends.
+
+ * "git log --ancestry-path A...B" did not work as expected, as it did
+   not pay attention to the fact that the merge base between A and B
+   was the bottom of the range being specified.
+
+ * Mac OS X does not like to write(2) more than INT_MAX number of
+   bytes; work it around by chopping write(2) into smaller pieces.
+
+ * Newer MacOS X encourages the programs to compile and link with
+   their CommonCrypto, not with OpenSSL.
+
+ * "git clone foo/bar:baz" cannot be a request to clone from a remote
+   over git-over-ssh specified in the scp style.  This case is now
+   detected and clones from a local repository at "foo/bar:baz".
+
+ * When $HOME is misconfigured to point at an unreadable directory, we
+   used to complain and die. Loosen the check.
+
+ * "git subtree" (in contrib/) had one codepath with loose error
+   checks to lose data at the remote side.
+
+ * "git fetch" into a shallow repository from a repository that does
+   not know about the shallow boundary commits (e.g. a different fork
+   from the repository the current shallow repository was cloned from)
+   did not work correctly.
+
+ * "git checkout foo" DWIMs the intended "upstream" and turns it into
+   "git checkout -t -b foo remotes/origin/foo". This codepath has been
+   updated to correctly take existing remote definitions into account.

+Git v1.8.5.4 Release Notes
+==========================
+
+Fixes since v1.8.5.3
+--------------------
+
+ * "git fetch --depth=0" was a no-op, and was silently ignored.
+   Diagnose it as an error.
+
+ * Remote repository URL expressed in scp-style host:path notation are
+   parsed more carefully (e.g. "foo/bar:baz" is local, "[::1]:/~user" asks
+   to connect to user's home directory on host at address ::1.
+
+ * SSL-related options were not passed correctly to underlying socket
+   layer in "git send-email".
+
+ * "git commit -v" appends the patch to the log message before
+   editing, and then removes the patch when the editor returned
+   control. However, the patch was not stripped correctly when the
+   first modified path was a submodule.
+
+ * "git mv A B/", when B does not exist as a directory, should error
+   out, but it didn't.
+
+ * When we figure out how many file descriptors to allocate for
+   keeping packfiles open, a system with non-working getrlimit() could
+   cause us to die(), but because we make this call only to get a
+   rough estimate of how many is available and we do not even attempt
+   to use up all file descriptors available ourselves, it is nicer to
+   fall back to a reasonable low value rather than dying.
+
+ * "git log --decorate" did not handle a tag pointed by another tag
+   nicely.
+
+ * "git add -A" (no other arguments) in a totally empty working tree
+   used to emit an error.
+
+ * There is no reason to have a hardcoded upper limit of the number of
+   parents for an octopus merge, created via the graft mechanism, but
+   there was.
+
+ * The implementation of 'git stash $cmd "stash@{...}"' did not quote
+   the stash argument properly and left it split at IFS whitespace.
+
+ * The documentation to "git pull" hinted there is an "-m" option
+   because it incorrectly shared the documentation with "git merge".
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v1.8.5.5 Release Notes
+==========================
+
+Fixes since v1.8.5.4
+--------------------
+
+ * The pathspec matching code, while comparing two trees (e.g. "git
+   diff A B -- path1 path2") was too aggressive and failed to match
+   some paths when multiple pathspecs were involved.
+
+ * "git repack --max-pack-size=8g" stopped being parsed correctly when
+   the command was reimplemented in C.
+
+ * A recent update to "git send-email" broke platforms where
+   /etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path
+   (e.g. Fedora rawhide).
+
+ * A handful of bugs around interpreting $branch@{upstream} notation
+   and its lookalike, when $branch part has interesting characters,
+   e.g. "@", and ":", have been fixed.
+
+ * "git clone" would fail to clone from a repository that has a ref
+   directly under "refs/", e.g. "refs/stash", because different
+   validation paths do different things on such a refname.  Loosen the
+   client side's validation to allow such a ref.
+
+ * "git log --left-right A...B" lost the "leftness" of commits
+   reachable from A when A is a tag as a side effect of a recent
+   bugfix.  This is a regression in 1.8.4.x series.
+
+ * "git merge-base --octopus" used to leave cleaning up suboptimal
+   result to the caller, but now it does the clean-up itself.
+
+ * "git mv A B/", when B does not exist as a directory, should error
+   out, but it didn't.

+Git v1.8.5.6 Release Notes
+==========================
+
+Fixes since v1.8.5.5
+--------------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v1.8.5 Release Notes
+========================
+
+Backward compatibility notes (for Git 2.0)
+------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics, which pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+The default prefix for "git svn" will change in Git 2.0.  For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it will place them under refs/remotes/origin/ unless
+it is told otherwise with its --prefix option.
+
+
+Updates since v1.8.4
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * "git-svn" has been taught to use the serf library, which is the
+   only option SVN 1.8.0 offers us when talking the HTTP protocol.
+
+ * "git-svn" talking over an https:// connection using the serf library
+   dumped core due to a bug in the serf library that SVN uses.  Work
+   around it on our side, even though the SVN side is being fixed.
+
+ * On MacOS X, we detected if the filesystem needs the "pre-composed
+   unicode strings" workaround, but did not automatically enable it.
+   Now we do.
+
+ * remote-hg remote helper misbehaved when interacting with a local Hg
+   repository relative to the home directory, e.g. "clone hg::~/there".
+
+ * imap-send ported to OS X uses Apple's security framework instead of
+   OpenSSL's.
+
+ * "git fast-import" treats an empty path given to "ls" as the root of
+   the tree.
+
+
+UI, Workflows & Features
+
+ * xdg-open can be used as a browser backend for "git web-browse"
+   (hence to show "git help -w" output), when available.
+
+ * "git grep" and "git show" pay attention to the "--textconv" option
+   when these commands are told to operate on blob objects (e.g. "git
+   grep -e pattern --textconv HEAD:Makefile").
+
+ * "git replace" helper no longer allows an object to be replaced with
+   another object of a different type to avoid confusion (you can
+   still manually craft such a replacement using "git update-ref", as an
+   escape hatch).
+
+ * "git status" no longer prints the dirty status information of
+   submodules for which submodule.$name.ignore is set to "all".
+
+ * "git rebase -i" honours core.abbrev when preparing the insn sheet
+   for editing.
+
+ * "git status" during a cherry-pick shows which original commit is
+   being picked.
+
+ * Instead of typing four capital letters "HEAD", you can say "@" now,
+   e.g. "git log @".
+
+ * "git check-ignore" follows the same rule as "git add" and "git
+   status" in that the ignore/exclude mechanism does not take effect
+   on paths that are already tracked.  With the "--no-index" option, it
+   can be used to diagnose which paths that should have been ignored
+   have been mistakenly added to the index.
+
+ * Some irrelevant "advice" messages that are shared with "git status"
+   output have been removed from the commit log template.
+
+ * "update-refs" learned a "--stdin" option to read multiple update
+   requests and perform them in an all-or-none fashion.
+
+ * Just like "make -C <directory>", "git -C <directory> ..." tells Git
+   to go there before doing anything else.
+
+ * Just like "git checkout -" knows to check out, and "git merge -"
+   knows to merge, the branch you were previously on, "git cherry-pick"
+   now understands "git cherry-pick -" to pick from the previous
+   branch.
+
+ * "git status" now omits the prefix to make its output a comment in a
+   commit log editor, which is not necessary for human consumption.
+   Scripts that parse the output of "git status" are advised to use
+   "git status --porcelain" instead, as its format is stable and easier
+   to parse.
+
+ * The ref syntax "foo^{tag}" (with the literal string "{tag}") peels a
+   tag ref to itself, i.e. it's a no-op., and fails if
+   "foo" is not a tag.  "git rev-parse --verify v1.0^{tag}" is
+   a more convenient way than "test $(git cat-file -t v1.0) = tag" to
+   check if v1.0 is a tag.
+
+ * "git branch -v -v" (and "git status") did not distinguish among a
+   branch that is not based on any other branch, a branch that is in
+   sync with its upstream branch, and a branch that is configured with an
+   upstream branch that no longer exists.
+
+ * Earlier we started rejecting any attempt to add the 0{40} object name to
+   the index and to tree objects, but it sometimes is necessary to
+   allow this to be able to use tools like filter-branch to correct such
+   broken tree objects.  "filter-branch" can again be used to do this.
+
+ * "git config" did not provide a way to set or access numbers larger
+   than a native "int" on the platform; it now provides 64-bit signed
+   integers on all platforms.
+
+ * "git pull --rebase" always chose to do the bog-standard flattening
+   rebase.  You can tell it to run "rebase --preserve-merges" with
+   "git pull --rebase=preserve" or by
+   setting "pull.rebase" configuration to "preserve".
+
+ * "git push --no-thin" actually disables the "thin pack transfer"
+   optimization.
+
+ * Magic pathspecs like ":(icase)makefile" (matches both Makefile
+   and makefile) and ":(glob)foo/**/bar" (matches "bar" in "foo"
+   and any subdirectory of "foo") can be used in more places.
+
+ * The "http.*" variables can now be specified for individual URLs.
+   For example,
+
+   [http]
+       sslVerify = true
+   [http "https://weak.example.com/"]
+       sslVerify = false
+
+   would flip http.sslVerify off only when talking to that specific
+   site.
+
+ * "git mv A B" when moving a submodule has been taught to
+   relocate the submodule's working tree and to adjust the paths in the
+   .gitmodules file.
+
+ * "git blame" can now take more than one -L option to discover the
+   origin of multiple blocks of lines.
+
+ * The http transport clients can optionally ask to save cookies
+   with the http.savecookies configuration variable.
+
+ * "git push" learned a more fine grained control over a blunt
+   "--force" when requesting a non-fast-forward update with the
+   "--force-with-lease=<refname>:<expected object name>" option.
+
+ * "git diff --diff-filter=<classes of changes>" can now take
+   lowercase letters (e.g. "--diff-filter=d") to mean "show
+   everything but these classes".  "git diff-files -q" is now a
+   deprecated synonym for "git diff-files --diff-filter=d".
+
+ * "git fetch" (hence "git pull" as well) learned to check
+   "fetch.prune" and "remote.*.prune" configuration variables and
+   to behave as if the "--prune" command line option was given.
+
+ * "git check-ignore -z" applied the NUL termination to both its input
+   (with --stdin) and its output, but "git check-attr -z" ignored the
+   option on the output side. Make both honor -z on the input and
+   output side the same way.
+
+ * "git whatchanged" may still be used by old timers, but mention of
+   it in documents meant for new users will only waste readers' time
+   wondering what the difference is between it and "git log".  Make it
+   less prominent in the general part of the documentation and explain
+   that it is merely a "git log" with different default behaviour in
+   its own document.
+
+
+Performance, Internal Implementation, etc.
+
+ * "git for-each-ref" when asking for merely the object name does not
+   have to parse the object pointed at by the refs; the codepath has
+   been optimized.
+
+ * The HTTP transport will try to use TCP keepalive when able.
+
+ * "git repack" is now written in C.
+
+ * Build procedure for MSVC has been updated.
+
+ * If a build-time fallback is set to "cat" instead of "less", we
+   should apply the same "no subprocess or pipe" optimization as we
+   apply to user-supplied GIT_PAGER=cat.
+
+ * Many commands use a --dashed-option as an operation mode selector
+   (e.g. "git tag --delete") that excludes other operation modes
+   (e.g. "git tag --delete --verify" is nonsense) and that cannot be
+   negated (e.g. "git tag --no-delete" is nonsense).  The parse-options
+   API learned a new OPT_CMDMODE macro to make it easier to implement
+   such a set of options.
+
+ * OPT_BOOLEAN() in the parse-options API was misdesigned to be "counting
+   up" but many subcommands expect it to behave as "on/off". Update
+   them to use OPT_BOOL() which is a proper boolean.
+
+ * "git gc" exits early without doing any work when it detects
+   that another instance of itself is already running.
+
+ * Under memory pressure and/or file descriptor pressure, we used to
+   close pack windows that are not used and also closed filehandles to
+   open but unused packfiles. These are now controlled separately
+   to better cope with the load.
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.4
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.4 in the maintenance
+track are contained in this release (see the maintenance releases' notes for
+details).
+
+ * An ancient How-To on serving Git repositories on an HTTP server
+   lacked a warning that it has been mostly superseded with a more
+   modern way.
+   (merge 6d52bc3 sc/doc-howto-dumb-http later to maint).
+
+ * The interaction between the use of Perl in our test suite and NO_PERL
+   has been clarified a bit.
+   (merge f8fc0ee jn/test-prereq-perl-doc later to maint).
+
+ * The synopsis section of the "git unpack-objects" documentation has been
+   clarified a bit.
+   (merge 61e2e22 vd/doc-unpack-objects later to maint).
+
+ * We did not generate the HTML version of the documentation to "git subtree"
+   in contrib/.
+   (merge 95c62fb jk/subtree-install-fix later to maint).
+
+ * A fast-import stream expresses a pathname with funny characters by
+   quoting them in C style; the remote-hg remote helper forgot to unquote
+   such a path.
+   (merge 1136265 ap/remote-hg-unquote-cquote later to maint).
+
+ * "git reset -p HEAD" has a codepath to special-case it to behave
+   differently from resetting to contents of other commits, but a
+   recent change broke it.
+
+ * Coloring around octopus merges in "log --graph" output was screwy.
+   (merge 339c17b hn/log-graph-color-octopus later to maint).
+
+ * "git checkout topic", when there is not yet a local "topic" branch
+   but there is a unique remote-tracking branch for a remote "topic"
+   branch, pretended as if "git checkout -t -b topic remote/$r/topic"
+   (for that unique remote $r) was run. This hack however was not
+   implemented for "git checkout topic --".
+   (merge bca3969 mm/checkout-auto-track-fix later to maint).
+
+ * One long-standing flaw in the pack transfer protocol used by "git
+   clone" was that there was no way to tell the other end which branch
+   "HEAD" points at, and the receiving end needed to guess.  A new
+   capability has been defined in the pack protocol to convey this
+   information so that cloning from a repository with more than one
+   branch pointing at the same commit where the HEAD is at now
+   reliably sets the initial branch in the resulting repository.
+   (merge 360a326 jc/upload-pack-send-symref later to maint).
+
+ * We did not handle cases where the http transport gets redirected during
+   the authorization request (e.g. from http:// to https://).
+   (merge 70900ed jk/http-auth-redirects later to maint).
+
+ * Bash prompting code to deal with an SVN remote as an upstream
+   was coded in a way unsupported by older Bash versions (3.x).
+   (merge 52ec889 sg/prompt-svn-remote-fix later to maint).
+
+ * The fall-back parsing of commit objects with broken author or
+   committer lines was less robust than ideal in picking up the
+   timestamps.
+   (merge 03818a4 jk/split-broken-ident later to maint).
+
+ * "git rev-list --objects ^v1.0^ v1.0" gave the v1.0 tag itself in the
+   output, but "git rev-list --objects v1.0^..v1.0" did not.
+   (merge 895c5ba jc/revision-range-unpeel later to maint).
+
+ * "git clone" wrote some progress messages to standard output, not
+   to standard error, and did not suppress them with the
+   --no-progress option.
+   (merge 643f918 jk/clone-progress-to-stderr later to maint).
+
+ * "format-patch --from=<whom>" forgot to omit an unnecessary in-body
+   from line, i.e. when <whom> is the same as the real author.
+   (merge 662cc30 jk/format-patch-from later to maint).
+
+ * "git shortlog" used to choke and die when there is a malformed
+   commit (e.g. missing authors); it now simply ignores such a commit
+   and keeps going.
+   (merge cd4f09e jk/shortlog-tolerate-broken-commit later to maint).
+
+ * "git merge-recursive" did not parse its "--diff-algorithm=" command
+   line option correctly.
+   (merge 6562928 jk/diff-algo later to maint).
+
+ * When running "fetch -q", a long silence while the sender side
+   computes the set of objects to send can be mistaken by proxies as
+   dropped connection.  The server side has been taught to send a
+   small empty messages to keep the connection alive.
+   (merge 115dedd jk/upload-pack-keepalive later to maint).
+
+ * "git rebase" had a portability regression in v1.8.4 that triggered a
+   bug in some BSD shell implementations.
+   (merge 99855dd mm/rebase-continue-freebsd-WB later to maint).
+
+ * "git branch --track" had a minor regression in v1.8.3.2 and later
+   that made it impossible to base your local work on anything but a
+   local branch of the upstream repository you are tracking.
+   (merge b0f49ff jh/checkout-auto-tracking later to maint).
+
+ * When the web server responds with "405 Method Not Allowed", "git
+   http-backend" should tell the client what methods are allowed with
+   the "Allow" header.
+   (merge 9247be0 bc/http-backend-allow-405 later to maint).
+
+ * When there is no sufficient overlap between old and new history
+   during a "git fetch" into a shallow repository, objects that the
+   sending side knows the receiving end has were unnecessarily sent.
+   (merge f21d2a7 nd/fetch-into-shallow later to maint).
+
+ * "git cvsserver" computed the permission mode bits incorrectly for
+   executable files.
+   (merge 1b48d56 jc/cvsserver-perm-bit-fix later to maint).
+
+ * When send-email obtains an error message to die with upon
+   failure to start an SSL session, it tried to read the error string
+   from a wrong place.
+   (merge 6cb0c88 bc/send-email-ssl-die-message-fix later to maint).
+
+ * The implementation of "add -i" has some crippling code to work around an
+   ActiveState Perl limitation but it by mistake also triggered on Git
+   for Windows where MSYS perl is used.
+   (merge df17e77 js/add-i-mingw later to maint).
+
+ * We made sure that we notice when the user-supplied GIT_DIR is actually a
+   gitfile, but did not do the same when the default ".git" is a
+   gitfile.
+   (merge 487a2b7 nd/git-dir-pointing-at-gitfile later to maint).
+
+ * When an object is not found after checking the packfiles and the
+   loose object directory, read_sha1_file() re-checks the packfiles to
+   prevent racing with a concurrent repacker; teach the same logic to
+   has_sha1_file().
+   (merge 45e8a74 jk/has-sha1-file-retry-packed later to maint).
+
+ * "git commit --author=$name", when $name is not in the canonical
+   "A. U. Thor <au.thor@example.xz>" format, looks for a matching name
+   from existing history, but did not consult mailmap to grab the
+   preferred author name.
+   (merge ea16794 ap/commit-author-mailmap later to maint).
+
+ * "git ls-files -k" needs to crawl only the part of the working tree
+   that may overlap the paths in the index to find killed files, but
+   shared code with the logic to find all the untracked files, which
+   made it unnecessarily inefficient.
+   (merge 680be04 jc/ls-files-killed-optim later to maint).
+
+ * The shortened commit object names in the insn sheet that is prepared at the
+   beginning of a "rebase -i" session can become ambiguous as the
+   rebasing progresses and the repository gains more commits. Make
+   sure the internal record is kept with full 40-hex object names.
+   (merge 75c6976 es/rebase-i-no-abbrev later to maint).
+
+ * "git rebase --preserve-merges" internally used the merge machinery
+   and as a side effect left the merge summary message in the log, but
+   when rebasing there is no need for the merge summary.
+   (merge a9f739c rt/rebase-p-no-merge-summary later to maint).
+
+ * A call to xread() was used without a loop around it to cope with short
+   reads in the codepath to stream new contents to a pack.
+   (merge e92527c js/xread-in-full later to maint).
+
+ * "git rebase -i" forgot that the comment character is
+   configurable while reading its insn sheet.
+   (merge 7bca7af es/rebase-i-respect-core-commentchar later to maint).
+
+ * The mailmap support code read past the allocated buffer when the
+   mailmap file ended with an incomplete line.
+   (merge f972a16 jk/mailmap-incomplete-line later to maint).
+
+ * We used to send a large request to read(2)/write(2) as a single
+   system call, which was bad from the latency point of view when
+   the operation needs to be killed, and also triggered an error on
+   broken 64-bit systems that refuse to read or write more than 2GB
+   in one go.
+   (merge a487916 sp/clip-read-write-to-8mb later to maint).
+
+ * "git fetch" that auto-followed tags incorrectly reused the
+   connection with Git-aware transport helper (like the sample "ext::"
+   helper shipped with Git).
+   (merge 0f73f8b jc/transport-do-not-use-connect-twice-in-fetch later to maint).
+
+ * "git log --full-diff -- <pathspec>" showed a huge diff for paths
+   outside the given <pathspec> for each commit, instead of showing
+   the change relative to the parent of the commit.  "git reflog -p"
+   had a similar problem.
+   (merge 838f9a1 tr/log-full-diff-keep-true-parents later to maint).

+ * Setting a submodule.*.path configuration variable to true (without
+   giving "= value") caused Git to segfault.
+   (merge 4b05440 jl/some-submodule-config-are-not-boolean later to maint).
+
+ * "git rebase -i" (there could be others, as the root cause is pretty
+   generic) fed a random, data dependent string to 'echo' and
+   expected it to come out literally, corrupting its error message.
+   (merge 89b0230 mm/no-shell-escape-in-die-message later to maint).
+
+ * Some people still use rather old versions of bash, which cannot
+   grok some constructs like 'printf -v varname' which the prompt and
+   completion code started to use recently.
+   (merge a44aa69 bc/completion-for-bash-3.0 later to maint).
+
+ * Code to read configuration from a blob object did not compile on
+   platforms with fgetc() etc. implemented as macros.
+   (merge 49d6cfa hv/config-from-blob later to maint-1.8.3).
+
+ * The recent "short-cut clone connectivity check" topic broke a
+   shallow repository when a fetch operation tries to auto-follow tags.
+   (merge 6da8bdc nd/fetch-pack-shallow-fix later to maint-1.8.3).

+Git v1.9.0 Release Notes
+========================
+
+Backward compatibility notes
+----------------------------
+
+"git submodule foreach $cmd $args" used to treat "$cmd $args" the same
+way "ssh" did, concatenating them into a single string and letting the
+shell unquote. Careless users who forget to sufficiently quote $args
+get their argument split at $IFS whitespaces by the shell, and got
+unexpected results due to this. Starting from this release, the
+command line is passed directly to the shell, if it has an argument.
+
+Read-only support for experimental loose-object format, in which users
+could optionally choose to write their loose objects for a short
+while between v1.4.3 and v1.5.3 era, has been dropped.
+
+The meanings of the "--tags" option to "git fetch" has changed; the
+command fetches tags _in addition to_ what is fetched by the same
+command line without the option.
+
+The way "git push $there $what" interprets the $what part given on the
+command line, when it does not have a colon that explicitly tells us
+what ref at the $there repository is to be updated, has been enhanced.
+
+A handful of ancient commands that have long been deprecated are
+finally gone (repo-config, tar-tree, lost-found, and peek-remote).
+
+
+Backward compatibility notes (for Git 2.0.0)
+--------------------------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default will change to the "simple"
+semantics, which pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+Use the user preference configuration variable "push.default" to
+change this.  If you are an old-timer who is used to the "matching"
+semantics, you can set the variable to "matching" to keep the
+traditional behaviour.  If you want to live in the future early, you
+can set it to "simple" today without waiting for Git 2.0.
+
+When "git add -u" (and "git add -A") is run inside a subdirectory and
+does not specify which paths to add on the command line, it
+will operate on the entire tree in Git 2.0 for consistency
+with "git commit -a" and other commands.  There will be no
+mechanism to make plain "git add -u" behave like "git add -u .".
+Current users of "git add -u" (without a pathspec) should start
+training their fingers to explicitly say "git add -u ."
+before Git 2.0 comes.  A warning is issued when these commands are
+run without a pathspec and when you have local changes outside the
+current directory, because the behaviour in Git 2.0 will be different
+from today's version in such a situation.
+
+In Git 2.0, "git add <path>" will behave as "git add -A <path>", so
+that "git add dir/" will notice paths you removed from the directory
+and record the removal.  Versions before Git 2.0, including this
+release, will keep ignoring removals, but the users who rely on this
+behaviour are encouraged to start using "git add --ignore-removal <path>"
+now before 2.0 is released.
+
+The default prefix for "git svn" will change in Git 2.0.  For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it will place them under refs/remotes/origin/ unless
+it is told otherwise with its --prefix option.
+
+
+Updates since v1.8.5
+--------------------
+
+Foreign interfaces, subsystems and ports.
+
+ * The HTTP transport, when talking GSS-Negotiate, uses "100
+   Continue" response to avoid having to rewind and resend a large
+   payload, which may not be always doable.
+
+ * Various bugfixes to remote-bzr and remote-hg (in contrib/).
+
+ * The build procedure is aware of MirBSD now.
+
+ * Various "git p4", "git svn" and "gitk" updates.
+
+
+UI, Workflows & Features
+
+ * Fetching from a shallowly-cloned repository used to be forbidden,
+   primarily because the codepaths involved were not carefully vetted
+   and we did not bother supporting such usage. This release attempts
+   to allow object transfer out of a shallowly-cloned repository in a
+   more controlled way (i.e. the receiver becomes a shallow repository
+   with a truncated history).
+
+ * Just like we give a reasonable default for "less" via the LESS
+   environment variable, we now specify a reasonable default for "lv"
+   via the "LV" environment variable when spawning the pager.
+
+ * Two-level configuration variable names in "branch.*" and "remote.*"
+   hierarchies, whose variables are predominantly three-level, were
+   not completed by hitting a <TAB> in bash and zsh completions.
+
+ * Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol'
+   remote-tracking branch from an earlier fetch was still there, would
+   error out, primarily because the command was not told that it is
+   allowed to lose any information on our side.  "git fetch --prune"
+   now can be used to remove 'frotz/nitfol' to make room for fetching and
+   storing the 'frotz' remote-tracking branch.
+
+ * "diff.orderfile=<file>" configuration variable can be used to
+   pretend as if the "-O<file>" option were given from the command
+   line of "git diff", etc.
+
+ * The negative pathspec syntax allows "git log -- . ':!dir'" to tell
+   us "I am interested in everything but 'dir' directory".
+
+ * "git difftool" shows how many different paths there are in total,
+   and how many of them have been shown so far, to indicate progress.
+
+ * "git push origin master" used to push our 'master' branch to update
+   the 'master' branch at the 'origin' repository.  This has been
+   enhanced to use the same ref mapping "git push origin" would use to
+   determine what ref at the 'origin' to be updated with our 'master'.
+   For example, with this configuration
+
+   [remote "origin"]
+      push = refs/heads/*:refs/review/*
+
+   that would cause "git push origin" to push out our local branches
+   to corresponding refs under refs/review/ hierarchy at 'origin',
+   "git push origin master" would update 'refs/review/master' over
+   there.  Alternatively, if push.default is set to 'upstream' and our
+   'master' is set to integrate with 'topic' from the 'origin' branch,
+   running "git push origin" while on our 'master' would update their
+   'topic' branch, and running "git push origin master" while on any
+   of our branches does the same.
+
+ * "gitweb" learned to treat ref hierarchies other than refs/heads as
+   if they are additional branch namespaces (e.g. refs/changes/ in
+   Gerrit).
+
+ * "git for-each-ref --format=..." learned a few formatting directives;
+   e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)".
+
+ * The command string given to "git submodule foreach" is passed
+   directly to the shell, without being eval'ed.  This is a backward
+   incompatible change that may break existing users.
+
+ * "git log" and friends learned the "--exclude=<glob>" option, to
+   allow people to say "list history of all branches except those that
+   match this pattern" with "git log --exclude='*/*' --branches".
+
+ * "git rev-parse --parseopt" learned a new "--stuck-long" option to
+   help scripts parse options with an optional parameter.
+
+ * The "--tags" option to "git fetch" no longer tells the command to
+   fetch _only_ the tags. It instead fetches tags _in addition to_
+   what are fetched by the same command line without the option.
+
+
+Performance, Internal Implementation, etc.
+
+ * When parsing a 40-hex string into the object name, the string is
+   checked to see if it can be interpreted as a ref so that a warning
+   can be given for ambiguity. The code kicked in even when the
+   core.warnambiguousrefs is set to false to squelch this warning, in
+   which case the cycles spent to look at the ref namespace were an
+   expensive no-op, as the result was discarded without being used.
+
+ * The naming convention of the packfiles has been updated; it used to
+   be based on the enumeration of names of the objects that are
+   contained in the pack, but now it also depends on how the packed
+   result is represented---packing the same set of objects using
+   different settings (or delta order) would produce a pack with
+   different name.
+
+ * "git diff --no-index" mode used to unnecessarily attempt to read
+   the index when there is one.
+
+ * The deprecated parse-options macro OPT_BOOLEAN has been removed;
+   use OPT_BOOL or OPT_COUNTUP in new code.
+
+ * A few duplicate implementations of prefix/suffix string comparison
+   functions have been unified to starts_with() and ends_with().
+
+ * The new PERLLIB_EXTRA makefile variable can be used to specify
+   additional directories Perl modules (e.g. the ones necessary to run
+   git-svn) are installed on the platform when building.
+
+ * "git merge-base" learned the "--fork-point" mode, that implements
+   the same logic used in "git pull --rebase" to find a suitable fork
+   point out of the reflog entries for the remote-tracking branch the
+   work has been based on.  "git rebase" has the same logic that can be
+   triggered with the "--fork-point" option.
+
+ * A third-party "receive-pack" (the responder to "git push") can
+   advertise the "no-thin" capability to tell "git push" not to use
+   the thin-pack optimization. Our receive-pack has always been
+   capable of accepting and fattening a thin-pack, and will continue
+   not to ask "git push" to use a non-thin pack.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v1.8.5
+------------------
+
+Unless otherwise noted, all the fixes since v1.8.5 in the maintenance
+track are contained in this release (see the maintenance releases' notes
+for details).
+
+ * The pathspec matching code, while comparing two trees (e.g. "git
+   diff A B -- path1 path2") was too aggressive and failed to match
+   some paths when multiple pathspecs were involved.
+
+ * "git repack --max-pack-size=8g" stopped being parsed correctly when
+   the command was reimplemented in C.
+
+ * An earlier update in v1.8.4.x to "git rev-list --objects" with
+   negative ref had a performance regression.
+   (merge 200abe7 jk/mark-edges-uninteresting later to maint).
+
+ * A recent update to "git send-email" broke platforms where
+   /etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path
+   (e.g. Fedora rawhide).
+
+ * A handful of bugs around interpreting $branch@{upstream} notation
+   and its lookalike, when $branch part has interesting characters,
+   e.g. "@", and ":", have been fixed.
+
+ * "git clone" would fail to clone from a repository that has a ref
+   directly under "refs/", e.g. "refs/stash", because different
+   validation paths do different things on such a refname.  Loosen the
+   client side's validation to allow such a ref.
+
+ * "git log --left-right A...B" lost the "leftness" of commits
+   reachable from A when A is a tag as a side effect of a recent
+   bugfix.  This is a regression in 1.8.4.x series.
+
+ * documentations to "git pull" hinted there is an "-m" option because
+   it incorrectly shared the documentation with "git merge".
+
+ * "git diff A B submod" and "git diff A B submod/" ought to have done
+   the same for a submodule "submod", but didn't.
+
+ * "git clone $origin foo\bar\baz" on Windows failed to create the
+   leading directories (i.e. a moral-equivalent of "mkdir -p").
+
+ * "submodule.*.update=checkout", when propagated from .gitmodules to
+   .git/config, turned into a "submodule.*.update=none", which did not
+   make much sense.
+   (merge efa8fd7 fp/submodule-checkout-mode later to maint).
+
+ * The implementation of 'git stash $cmd "stash@{...}"' did not quote
+   the stash argument properly and left it split at IFS whitespace.
+
+ * The "--[no-]informative-errors" options to "git daemon" were parsed
+   a bit too loosely, allowing any other string after these option
+   names.
+
+ * There is no reason to have a hardcoded upper limit for the number of
+   parents of an octopus merge, created via the graft mechanism, but
+   there was.
+
+ * The basic test used to leave unnecessary trash directories in the
+   t/ directory.
+   (merge 738a8be jk/test-framework-updates later to maint).
+
+ * "git merge-base --octopus" used to leave cleaning up suboptimal
+   result to the caller, but now it does the clean-up itself.
+
+ * A "gc" process running as a different user should be able to stop a
+   new "gc" process from starting, but it didn't.
+
+ * An earlier "clean-up" introduced an unnecessary memory leak.
+
+ * "git add -A" (no other arguments) in a totally empty working tree
+   used to emit an error.
+
+ * "git log --decorate" did not handle a tag pointed by another tag
+   nicely.
+
+ * When we figure out how many file descriptors to allocate for
+   keeping packfiles open, a system with non-working getrlimit() could
+   cause us to die(), but because we make this call only to get a
+   rough estimate of how many are available and we do not even attempt
+   to use up all available file descriptors ourselves, it is nicer to
+   fall back to a reasonable low value rather than dying.
+
+ * read_sha1_file(), that is the workhorse to read the contents given
+   an object name, honoured object replacements, but there was no
+   corresponding mechanism to sha1_object_info() that was used to
+   obtain the metainfo (e.g. type & size) about the object.  This led
+   callers to weird inconsistencies.
+   (merge 663a856 cc/replace-object-info later to maint).
+
+ * "git cat-file --batch=", an admittedly useless command, did not
+   behave very well.
+
+ * "git rev-parse <revs> -- <paths>" did not implement the usual
+   disambiguation rules the commands in the "git log" family used in
+   the same way.
+
+ * "git mv A B/", when B does not exist as a directory, should error
+   out, but it didn't.
+
+ * A workaround to an old bug in glibc prior to glibc 2.17 has been
+   retired; this would remove a side effect of the workaround that
+   corrupts system error messages in non-C locales.
+
+ * SSL-related options were not passed correctly to underlying socket
+   layer in "git send-email".
+
+ * "git commit -v" appends the patch to the log message before
+   editing, and then removes the patch when the editor returned
+   control. However, the patch was not stripped correctly when the
+   first modified path was a submodule.
+
+ * "git fetch --depth=0" was a no-op, and was silently ignored.
+   Diagnose it as an error.
+
+ * Remote repository URLs expressed in scp-style host:path notation are
+   parsed more carefully (e.g. "foo/bar:baz" is local, "[::1]:/~user" asks
+   to connect to user's home directory on host at address ::1.
+
+ * "git diff -- ':(icase)makefile'" was unnecessarily rejected at the
+   command line parser.
+
+ * "git cat-file --batch-check=ok" did not check the existence of
+   the named object.
+
+ * "git am --abort" sometimes complained about not being able to write
+   a tree with an 0{40} object in it.
+
+ * Two processes creating loose objects at the same time could have
+   failed unnecessarily when the name of their new objects started
+   with the same byte value, due to a race condition.

+Git v1.9.1 Release Notes
+========================
+
+Fixes since v1.9.0
+------------------
+
+ * "git clean -d pathspec" did not use the given pathspec correctly
+   and ended up cleaning too much.
+
+ * "git difftool" misbehaved when the repository is bound to the
+   working tree with the ".git file" mechanism, where a textual file
+   ".git" tells us where it is.
+
+ * "git push" did not pay attention to branch.*.pushremote if it is
+   defined earlier than remote.pushdefault; the order of these two
+   variables in the configuration file should not matter, but it did
+   by mistake.
+
+ * Codepaths that parse timestamps in commit objects have been
+   tightened.
+
+ * "git diff --external-diff" incorrectly fed the submodule directory
+   in the working tree to the external diff driver when it knew it is
+   the same as one of the versions being compared.
+
+ * "git reset" needs to refresh the index when working in a working
+   tree (it can also be used to match the index to the HEAD in an
+   otherwise bare repository), but it failed to set up the working
+   tree properly, causing GIT_WORK_TREE to be ignored.
+
+ * "git check-attr" when working on a repository with a working tree
+   did not work well when the working tree was specified via the
+   --work-tree (and obviously with --git-dir) option.
+
+ * "merge-recursive" was broken in 1.7.7 era and stopped working in
+   an empty (temporary) working tree, when there are renames
+   involved.  This has been corrected.
+
+ * "git rev-parse" was loose in rejecting command line arguments
+   that do not make sense, e.g. "--default" without the required
+   value for that option.
+
+ * include.path variable (or any variable that expects a path that
+   can use ~username expansion) in the configuration file is not a
+   boolean, but the code failed to check it.
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+   correct status value.
+
+ * Attempting to deepen a shallow repository by fetching over smart
+   HTTP transport failed in the protocol exchange, when no-done
+   extension was used.  The fetching side waited for the list of
+   shallow boundary commits after the sending end stopped talking to
+   it.
+
+ * Allow "git cmd path/", when the 'path' is where a submodule is
+   bound to the top-level working tree, to match 'path', despite the
+   extra and unnecessary trailing slash (such a slash is often
+   given by command line completion).

+Git v1.9.2 Release Notes
+========================
+
+Fixes since v1.9.1
+------------------
+
+ * Documentation and in-code comments had many instances of mistaken
+   use of "nor", which have been corrected.
+
+ * "git fetch --prune", when the right-hand-side of multiple fetch
+   refspecs overlap (e.g. storing "refs/heads/*" to
+   "refs/remotes/origin/*", while storing "refs/frotz/*" to
+   "refs/remotes/origin/fr/*"), aggressively thought that lack of
+   "refs/heads/fr/otz" on the origin site meant we should remove
+   "refs/remotes/origin/fr/otz" from us, without checking their
+   "refs/frotz/otz" first.
+
+   Note that such a configuration is inherently unsafe (think what
+   should happen when "refs/heads/fr/otz" does appear on the origin
+   site), but that is not a reason not to be extra careful.
+
+ * "git update-ref --stdin" did not fail a request to create a ref
+   when the ref already existed.
+
+ * "git diff --no-index -Mq a b" fell into an infinite loop.
+
+ * When it is not necessary to edit a commit log message (e.g. "git
+   commit -m" is given a message without specifying "-e"), we used to
+   disable the spawning of the editor by overriding GIT_EDITOR, but
+   this means all the uses of the editor, other than to edit the
+   commit log message, are also affected.
+
+ * "git status --porcelain --branch" showed its output with labels
+   "ahead/behind/gone" translated to the user's locale.
+
+ * "git mv" that moves a submodule forgot to adjust the array that
+   uses to keep track of which submodules were to be moved to update
+   its configuration.
+
+ * Length limit for the pathname used when removing a path in a deep
+   subdirectory has been removed to avoid buffer overflows.
+
+ * The test helper lib-terminal always run an actual test_expect_*
+   when included, which screwed up with the use of skil-all that may
+   have to be done later.
+
+ * "git index-pack" used a wrong variable to name the keep-file in an
+   error message when the file cannot be written or closed.
+
+ * "rebase -i" produced a broken insn sheet when the title of a commit
+   happened to contain '\n' (or ended with '\c') due to a careless use
+   of 'echo'.
+
+ * There were a few instances of 'git-foo' remaining in the
+   documentation that should have been spelled 'git foo'.
+
+ * Serving objects from a shallow repository needs to write a
+   new file to hold the temporary shallow boundaries but it was not
+   cleaned when we exit due to die() or a signal.
+
+ * When "git stash pop" stops after failing to apply the stash
+   (e.g. due to conflicting changes), the stash is not dropped. State
+   that explicitly in the output to let the users know.
+
+ * The labels in "git status" output that describe the nature of
+   conflicts (e.g. "both deleted") were limited to 20 bytes, which was
+   too short for some l10n (e.g. fr).

+Git v1.9.5 Release Notes
+========================
+
+Fixes since v1.9.4
+------------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.0 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+When "git push [$there]" does not say what to push, we have used the
+traditional "matching" semantics so far (all your branches were sent
+to the remote as long as there already are branches of the same name
+over there).  In Git 2.0, the default is now the "simple" semantics,
+which pushes:
+
+ - only the current branch to the branch with the same name, and only
+   when the current branch is set to integrate with that remote
+   branch, if you are pushing to the same remote as you fetch from; or
+
+ - only the current branch to the branch with the same name, if you
+   are pushing to a remote that is not where you usually fetch from.
+
+You can use the configuration variable "push.default" to change
+this.  If you are an old-timer who wants to keep using the
+"matching" semantics, you can set the variable to "matching", for
+example.  Read the documentation for other possibilities.
+
+When "git add -u" and "git add -A" are run inside a subdirectory
+without specifying which paths to add on the command line, they
+operate on the entire tree for consistency with "git commit -a" and
+other commands (these commands used to operate only on the current
+subdirectory).  Say "git add -u ." or "git add -A ." if you want to
+limit the operation to the current directory.
+
+"git add <path>" is the same as "git add -A <path>" now, so that
+"git add dir/" will notice paths you removed from the directory and
+record the removal.  In older versions of Git, "git add <path>" used
+to ignore removals.  You can say "git add --ignore-removal <path>" to
+add only added or modified paths in <path>, if you really want to.
+
+The "-q" option to "git diff-files", which does *NOT* mean "quiet",
+has been removed (it told Git to ignore deletion, which you can do
+with "git diff-files --diff-filter=d").
+
+"git request-pull" lost a few "heuristics" that often led to mistakes.
+
+The default prefix for "git svn" has changed in Git 2.0.  For a long
+time, "git svn" created its remote-tracking branches directly under
+refs/remotes, but it now places them under refs/remotes/origin/ unless
+it is told otherwise with its "--prefix" option.
+
+
+Updates since v1.9 series
+-------------------------
+
+UI, Workflows & Features
+
+ * The "multi-mail" post-receive hook (in contrib/) has been updated
+   to a more recent version from upstream.
+
+ * The "remote-hg/bzr" remote-helper interfaces (used to be in
+   contrib/) are no more.  They are now maintained separately as
+   third-party plug-ins in their own repositories.
+
+ * "git gc --aggressive" learned "--depth" option and
+   "gc.aggressiveDepth" configuration variable to allow use of a less
+   insane depth than the built-in default value of 250.
+
+ * "git log" learned the "--show-linear-break" option to show where a
+   single strand-of-pearls is broken in its output.
+
+ * The "rev-parse --parseopt" mechanism used by scripted Porcelains to
+   parse command-line options and to give help text learned to take
+   the argv-help (the placeholder string for an option parameter,
+   e.g. "key-id" in "--gpg-sign=<key-id>").
+
+ * The pattern to find where the function begins in C/C++ used in
+   "diff" and "grep -p" has been updated to improve viewing C++
+   sources.
+
+ * "git rebase" learned to interpret a lone "-" as "@{-1}", the
+   branch that we were previously on.
+
+ * "git commit --cleanup=<mode>" learned a new mode, scissors.
+
+ * "git tag --list" output can be sorted using "version sort" with
+   "--sort=version:refname".
+
+ * Discard the accumulated "heuristics" to guess from which branch the
+   result wants to be pulled from and make sure that what the end user
+   specified is not second-guessed by "git request-pull", to avoid
+   mistakes.  When you pushed out your 'master' branch to your public
+   repository as 'for-linus', use the new "master:for-linus" syntax to
+   denote the branch to be pulled.
+
+ * "git grep" learned to behave in a way similar to native grep when
+   "-h" (no header) and "-c" (count) options are given.
+
+ * "git push" via transport-helper interface has been updated to
+   allow forced ref updates in a way similar to the natively
+   supported transports.
+
+ * The "simple" mode is the default for "git push".
+
+ * "git add -u" and "git add -A", when run without any pathspec, is a
+   tree-wide operation even when run inside a subdirectory of a
+   working tree.
+
+ * "git add <path>" is the same as "git add -A <path>" now.
+
+ * "core.statinfo" configuration variable, which is a
+   never-advertised synonym to "core.checkstat", has been removed.
+
+ * The "-q" option to "git diff-files", which does *NOT* mean
+   "quiet", has been removed (it told Git to ignore deletion, which
+   you can do with "git diff-files --diff-filter=d").
+
+ * Server operators can loosen the "tips of refs only" restriction for
+   the remote archive service with the uploadarchive.allowUnreachable
+   configuration option.
+
+ * The progress indicators from various time-consuming commands have
+   been marked for i18n/l10n.
+
+ * "git notes -C <blob>" diagnoses as an error an attempt to use an
+   object that is not a blob.
+
+ * "git config" learned to read from the standard input when "-" is
+   given as the value to its "--file" parameter (attempting an
+   operation to update the configuration in the standard input is
+   rejected, of course).
+
+ * Trailing whitespaces in .gitignore files, unless they are quoted
+   for fnmatch(3), e.g. "path\ ", are warned and ignored.  Strictly
+   speaking, this is a backward-incompatible change, but very unlikely
+   to bite any sane user and adjusting should be obvious and easy.
+
+ * Many commands that create commits, e.g. "pull" and "rebase",
+   learned to take the "--gpg-sign" option on the command line.
+
+ * "git commit" can be told to always GPG sign the resulting commit
+   by setting the "commit.gpgsign" configuration variable to "true"
+   (the command-line option "--no-gpg-sign" should override it).
+
+ * "git pull" can be told to only accept fast-forward by setting the
+   new "pull.ff" configuration variable.
+
+ * "git reset" learned the "-N" option, which does not reset the index
+   fully for paths the index knows about but the tree-ish the command
+   resets to does not (these paths are kept as intend-to-add entries).
+
+
+Performance, Internal Implementation, etc.
+
+ * The compilation options to port to AIX and to MSVC have been
+   updated.
+
+ * We started using wildmatch() in place of fnmatch(3) a few releases
+   ago; complete the process and stop using fnmatch(3).
+
+ * Uses of curl's "multi" interface and "easy" interface do not mix
+   well when we attempt to reuse outgoing connections.  Teach the RPC
+   over HTTP code, used in the smart HTTP transport, not to use the
+   "easy" interface.
+
+ * The bitmap-index feature from JGit has been ported, which should
+   significantly improve performance when serving objects from a
+   repository that uses it.
+
+ * The way "git log --cc" shows a combined diff against multiple
+   parents has been optimized.
+
+ * The prefixcmp() and suffixcmp() functions are gone.  Use
+   starts_with() and ends_with(), and also consider if skip_prefix()
+   suits your needs better when using the former.
+
+
+Also contains various documentation updates and code clean-ups.  Many
+of them came from flurry of activities as GSoC candidate microproject
+exercises.
+
+
+Fixes since v1.9 series
+-----------------------
+
+Unless otherwise noted, all the fixes since v1.9 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git p4" was broken in 1.9 release to deal with changes in binary
+   files.
+   (merge 749b668 cl/p4-use-diff-tree later to maint).
+
+ * The shell prompt script (in contrib/), when using the PROMPT_COMMAND
+   interface, used an unsafe construct when showing the branch name in
+   $PS1.
+   (merge 1e4119c8 rh/prompt-pcmode-avoid-eval-on-refname later to maint).
+
+ * "git rebase" used a POSIX shell construct FreeBSD's /bin/sh does not
+   work well with.
+   (merge 8cd6596 km/avoid-non-function-return-in-rebase later to maint).
+
+ * zsh prompt (in contrib/) leaked unnecessary error messages.
+
+ * Bash completion (in contrib/) did not complete the refs and remotes
+   correctly given "git pu<TAB>" when "pu" is aliased to "push".
+
+ * Some more Unicode code points, defined in Unicode 6.3 as having zero
+   width, have been taught to our display column counting logic.
+   (merge d813ab9 tb/unicode-6.3-zero-width later to maint).
+
+ * Some tests used shell constructs that did not work well on FreeBSD
+   (merge ff7a1c6 km/avoid-bs-in-shell-glob later to maint).
+   (merge 00764ca km/avoid-cp-a later to maint).
+
+ * "git update-ref --stdin" did not fail a request to create a ref
+   when the ref already existed.
+   (merge b9d56b5 mh/update-ref-batch-create-fix later to maint).
+
+ * "git diff --no-index -Mq a b" fell into an infinite loop.
+   (merge ad1c3fb jc/fix-diff-no-index-diff-opt-parse later to maint).
+
+ * "git fetch --prune", when the right-hand side of multiple fetch
+   refspecs overlap (e.g. storing "refs/heads/*" to
+   "refs/remotes/origin/*", while storing "refs/frotz/*" to
+   "refs/remotes/origin/fr/*"), aggressively thought that lack of
+   "refs/heads/fr/otz" on the origin site meant we should remove
+   "refs/remotes/origin/fr/otz" from us, without checking their
+   "refs/frotz/otz" first.
+
+   Note that such a configuration is inherently unsafe (think what
+   should happen when "refs/heads/fr/otz" does appear on the origin
+   site), but that is not a reason not to be extra careful.
+   (merge e6f6371 cn/fetch-prune-overlapping-destination later to maint).
+
+ * "git status --porcelain --branch" showed its output with labels
+   "ahead/behind/gone" translated to the user's locale.
+   (merge 7a76c28 mm/status-porcelain-format-i18n-fix later to maint).
+
+ * A stray environment variable $prefix could have leaked into and
+   affected the behaviour of the "subtree" script (in contrib/).
+
+ * When it is not necessary to edit a commit log message (e.g. "git
+   commit -m" is given a message without specifying "-e"), we used to
+   disable the spawning of the editor by overriding GIT_EDITOR, but
+   this means all the uses of the editor, other than to edit the
+   commit log message, are also affected.
+   (merge b549be0 bp/commit-p-editor later to maint).
+
+ * "git mv" that moves a submodule forgot to adjust the array that
+   uses to keep track of which submodules were to be moved to update
+   its configuration.
+   (merge fb8a4e8 jk/mv-submodules-fix later to maint).
+
+ * Length limit for the pathname used when removing a path in a deep
+   subdirectory has been removed to avoid buffer overflows.
+   (merge 2f29e0c mh/remove-subtree-long-pathname-fix later to maint).
+
+ * The test helper lib-terminal always run an actual test_expect_*
+   when included, which screwed up with the use of skil-all that may
+   have to be done later.
+   (merge 7e27173 jk/lib-terminal-lazy later to maint).
+
+ * "git index-pack" used a wrong variable to name the keep-file in an
+   error message when the file cannot be written or closed.
+   (merge de983a0 nd/index-pack-error-message later to maint).
+
+ * "rebase -i" produced a broken insn sheet when the title of a commit
+   happened to contain '\n' (or ended with '\c') due to a careless use
+   of 'echo'.
+   (merge cb1aefd us/printf-not-echo later to maint).
+
+ * There were a few instances of 'git-foo' remaining in the
+   documentation that should have been spelled 'git foo'.
+   (merge 3c3e6f5 rr/doc-merge-strategies later to maint).
+
+ * Serving objects from a shallow repository needs to write a
+   new file to hold the temporary shallow boundaries, but it was not
+   cleaned when we exit due to die() or a signal.
+   (merge 7839632 jk/shallow-update-fix later to maint).
+
+ * When "git stash pop" stops after failing to apply the stash
+   (e.g. due to conflicting changes), the stash is not dropped. State
+   that explicitly in the output to let the users know.
+   (merge 2d4c993 jc/stash-pop-not-popped later to maint).
+
+ * The labels in "git status" output that describe the nature of
+   conflicts (e.g. "both deleted") were limited to 20 bytes, which was
+   too short for some l10n (e.g. fr).
+   (merge c7cb333 jn/wt-status later to maint).
+
+ * "git clean -d pathspec" did not use the given pathspec correctly
+   and ended up cleaning too much.
+   (merge 1f2e108 jk/clean-d-pathspec later to maint).
+
+ * "git difftool" misbehaved when the repository is bound to the
+   working tree with the ".git file" mechanism, where a textual file
+   ".git" tells us where it is.
+   (merge fcfec8b da/difftool-git-files later to maint).
+
+ * "git push" did not pay attention to "branch.*.pushremote" if it is
+   defined earlier than "remote.pushdefault"; the order of these two
+   variables in the configuration file should not matter, but it did
+   by mistake.
+   (merge 98b406f jk/remote-pushremote-config-reading later to maint).
+
+ * Code paths that parse timestamps in commit objects have been
+   tightened.
+   (merge f80d1f9 jk/commit-dates-parsing-fix later to maint).
+
+ * "git diff --external-diff" incorrectly fed the submodule directory
+   in the working tree to the external diff driver when it knew that it
+   is the same as one of the versions being compared.
+   (merge aba4727 tr/diff-submodule-no-reuse-worktree later to maint).
+
+ * "git reset" needs to refresh the index when working in a working
+   tree (it can also be used to match the index to the HEAD in an
+   otherwise bare repository), but it failed to set up the working
+   tree properly, causing GIT_WORK_TREE to be ignored.
+   (merge b7756d4 nd/reset-setup-worktree later to maint).
+
+ * "git check-attr" when working on a repository with a working tree
+   did not work well when the working tree was specified via the
+   "--work-tree" (and obviously with "--git-dir") option.
+   (merge cdbf623 jc/check-attr-honor-working-tree later to maint).
+
+ * "merge-recursive" was broken in 1.7.7 era and stopped working in
+   an empty (temporary) working tree, when there are renames
+   involved.  This has been corrected.
+   (merge 6e2068a bk/refresh-missing-ok-in-merge-recursive later to maint.)
+
+ * "git rev-parse" was loose in rejecting command-line arguments
+   that do not make sense, e.g. "--default" without the required
+   value for that option.
+   (merge a43219f ds/rev-parse-required-args later to maint.)
+
+ * "include.path" variable (or any variable that expects a path that
+   can use ~username expansion) in the configuration file is not a
+   boolean, but the code failed to check it.
+   (merge 67beb60 jk/config-path-include-fix later to maint.)
+
+ * Commands that take pathspecs on the command line misbehaved when
+   the pathspec is given as an absolute pathname (which is a
+   practice not particularly encouraged) that points at a symbolic
+   link in the working tree.
+   (merge 6127ff6 mw/symlinks later to maint.)
+
+ * "git diff --quiet -- pathspec1 pathspec2" sometimes did not return
+   the correct status value.
+   (merge f34b205 nd/diff-quiet-stat-dirty later to maint.)
+
+ * Attempting to deepen a shallow repository by fetching over smart
+   HTTP transport failed in the protocol exchange, when the no-done
+   extension was used.  The fetching side waited for the list of
+   shallow boundary commits after the sending side stopped talking to
+   it.
+   (merge 0232852 nd/http-fetch-shallow-fix later to maint.)
+
+ * Allow "git cmd path/", when the 'path' is where a submodule is
+   bound to the top-level working tree, to match 'path', despite the
+   extra and unnecessary trailing slash (such a slash is often
+   given by command-line completion).
+   (merge 2e70c01 nd/submodule-pathspec-ending-with-slash later to maint.)
+
+ * Documentation and in-code comments had many instances of mistaken
+   use of "nor", which have been corrected.
+   (merge 235e8d5 jl/nor-or-nand-and later to maint).

+Git v2.0.1 Release Notes
+========================
+
+ * We used to unconditionally disable the pager in the pager process
+   we spawn to feed out output, but that prevented people who want to
+   run "less" within "less" from doing so.
+
+ * Tools that read diagnostic output in our standard error stream do
+   not want to see terminal control sequence (e.g. erase-to-eol).
+   Detect them by checking if the standard error stream is connected
+   to a tty.
+ * Reworded the error message given upon a failure to open an existing
+   loose object file due to e.g. permission issues; it was reported as
+   the object being corrupt, but that is not quite true.
+
+ * "git log -2master" is a common typo that shows two commits starting
+   from whichever random branch that is not 'master' that happens to
+   be checked out currently.
+
+ * The "%<(10,trunc)%s" pretty format specifier in the log family of
+   commands is used to truncate the string to a given length (e.g. 10
+   in the example) with padding to column-align the output, but did
+   not take into account that number of bytes and number of display
+   columns are different.
+
+ * The "mailmap.file" configuration option did not support the tilde
+   expansion (i.e. ~user/path and ~/path).
+
+ * The completion scripts (in contrib/) did not know about quite a few
+   options that are common between "git merge" and "git pull", and a
+   couple of options unique to "git merge".
+
+ * "--ignore-space-change" option of "git apply" ignored the spaces
+   at the beginning of line too aggressively, which is inconsistent
+   with the option of the same name "diff" and "git diff" have.
+
+ * "git blame" miscounted number of columns needed to show localized
+   timestamps, resulting in jaggy left-side-edge of the source code
+   lines in its output.
+
+ * "git blame" assigned the blame to the copy in the working-tree if
+   the repository is set to core.autocrlf=input and the file used CRLF
+   line endings.
+
+ * "git commit --allow-empty-message -C $commit" did not work when the
+   commit did not have any log message.
+
+ * "git diff --find-copies-harder" sometimes pretended as if the mode
+   bits have changed for paths that are marked with assume-unchanged
+   bit.
+
+ * "git format-patch" did not enforce the rule that the "--follow"
+   option from the log/diff family of commands must be used with
+   exactly one pathspec.
+
+ * "git gc --auto" was recently changed to run in the background to
+   give control back early to the end-user sitting in front of the
+   terminal, but it forgot that housekeeping involving reflogs should
+   be done without other processes competing for accesses to the refs.
+
+ * "git grep -O" to show the lines that hit in the pager did not work
+   well with case insensitive search.  We now spawn "less" with its
+   "-I" option when it is used as the pager (which is the default).
+
+ * We used to disable threaded "git index-pack" on platforms without
+   thread-safe pread(); use a different workaround for such
+   platforms to allow threaded "git index-pack".
+
+ * The error reporting from "git index-pack" has been improved to
+   distinguish missing objects from type errors.
+
+ * "git mailinfo" used to read beyond the end of header string while
+   parsing an incoming e-mail message to extract the patch.
+
+ * On a case insensitive filesystem, merge-recursive incorrectly
+   deleted the file that is to be renamed to a name that is the same
+   except for case differences.
+
+ * "git pack-objects" unnecessarily copied the previous contents when
+   extending the hashtable, even though it will populate the table
+   from scratch anyway.
+
+ * "git rerere forget" did not work well when merge.conflictstyle
+   was set to a non-default value.
+
+ * "git remote rm" and "git remote prune" can involve removing many
+   refs at once, which is not a very efficient thing to do when very
+   many refs exist in the packed-refs file.
+
+ * "git log --exclude=<glob> --all | git shortlog" worked as expected,
+   but "git shortlog --exclude=<glob> --all", which is supposed to be
+   identical to the above pipeline, was not accepted at the command
+   line argument parser level.
+
+ * The autostash mode of "git rebase -i" did not restore the dirty
+   working tree state if the user aborted the interactive rebase by
+   emptying the insn sheet.
+
+ * "git show -s" (i.e. show log message only) used to incorrectly emit
+   an extra blank line after a merge commit.
+
+ * "git status", even though it is a read-only operation, tries to
+   update the index with refreshed lstat(2) info to optimize future
+   accesses to the working tree opportunistically, but this could
+   race with a "read-write" operation that modify the index while it
+   is running.  Detect such a race and avoid overwriting the index.
+
+ * "git status" (and "git commit") behaved as if changes in a modified
+   submodule are not there if submodule.*.ignore configuration is set,
+   which was misleading.  The configuration is only to unclutter diff
+   output during the course of development, and should not to hide
+   changes in the "status" output to cause the users forget to commit
+   them.
+
+ * The mode to run tests with HTTP server tests disabled was broken.

+Git v2.0.2 Release Notes
+========================
+
+ * Documentation for "git submodule sync" forgot to say that the subcommand
+   can take the "--recursive" option.
+
+ * Mishandling of patterns in .gitignore that has trailing SPs quoted
+   with backslashes (e.g. ones that end with "\ ") have been
+   corrected.
+
+ * Recent updates to "git repack" started to duplicate objects that
+   are in packfiles marked with .keep flag into the new packfile by
+   mistake.
+
+ * "git clone -b brefs/tags/bar" would have mistakenly thought we were
+   following a single tag, even though it was a name of the branch,
+   because it incorrectly used strstr().
+
+ * "%G" (nothing after G) is an invalid pretty format specifier, but
+   the parser did not notice it as garbage.
+
+ * Code to avoid adding the same alternate object store twice was
+   subtly broken for a long time, but nobody seems to have noticed.
+
+ * A handful of code paths had to read the commit object more than
+   once when showing header fields that are usually not parsed.  The
+   internal data structure to keep track of the contents of the commit
+   object has been updated to reduce the need for this double-reading,
+   and to allow the caller find the length of the object.
+
+ * During "git rebase --merge", a conflicted patch could not be
+   skipped with "--skip" if the next one also conflicted.

+Git v2.0.3 Release Notes
+========================
+
+ * An ancient rewrite passed a wrong pointer to a curl library
+   function in a rarely used code path.
+
+ * "filter-branch" left an empty single-parent commit that results when
+   all parents of a merge commit gets mapped to the same commit, even
+   under "--prune-empty".
+
+ * "log --show-signature" incorrectly decided the color to paint a
+   mergetag that was and was not correctly validated.
+
+ * "log --show-signature" did not pay attention to "--graph" option.
+
+Also a lot of fixes to the tests and some updates to the docs are
+included.

+Git v2.0.5 Release Notes
+========================
+
+Fixes since v2.0.4
+------------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.1 Release Notes
+======================
+
+Backward compatibility notes
+----------------------------
+
+ * The default value we give to the environment variable LESS has been
+   changed from "FRSX" to "FRX", losing "S" (chop long lines instead
+   of wrapping).  Existing users who prefer not to see line-wrapped
+   output may want to set
+
+     $ git config core.pager "less -S"
+
+   to restore the traditional behaviour.  It is expected that people
+   find output from most subcommands easier to read with the new
+   default, except for "blame" which tends to produce really long
+   lines.  To override the new default only for "git blame", you can
+   do this:
+
+     $ git config pager.blame "less -S"
+
+ * A few disused directories in contrib/ have been retired.
+
+
+Updates since v2.0
+------------------
+
+UI, Workflows & Features
+
+ * Since the very beginning of Git, we gave the LESS environment a
+   default value "FRSX" when we spawn "less" as the pager.  "S" (chop
+   long lines instead of wrapping) has been removed from this default
+   set of options, because it is more or less a personal taste thing,
+   as opposed to the others that have good justifications (i.e. "R" is
+   very much justified because many kinds of output we produce are
+   colored and "FX" is justified because output we produce is often
+   shorter than a page).
+
+ * The logic and data used to compute the display width needed for
+   UTF-8 strings have been updated to match Unicode 7.0 better.
+
+ * HTTP-based transports learned to better propagate the error messages from
+   the webserver to the client coming over the HTTP transport.
+
+ * The completion script for bash (in contrib/) has been updated to
+   better handle aliases that define a complex sequence of commands.
+
+ * The "core.preloadindex" configuration variable is enabled by default,
+   allowing modern platforms to take advantage of their
+   multiple cores.
+
+ * "git clone" applies the "if cloning from a local disk, physically
+   copy the repository using hardlinks, unless otherwise told not to with
+   --no-local" optimization when the url.*.insteadOf mechanism rewrites a
+   remote-repository "git clone $URL" into a
+   clone from a local disk.
+
+ * "git commit --date=<date>" option learned more
+   timestamp formats, including "--date=now".
+
+ * The `core.commentChar` configuration variable is used to specify a
+   custom comment character (other than the default "#") for
+   the commit message editor.  This can be set to `auto` to attempt to
+   choose a different character that does not conflict with any that
+   already starts a line in the message being edited, for cases like
+   "git commit --amend".
+
+ * "git format-patch" learned --signature-file=<file> to add the contents
+   of a file as a signature to the mail message it produces.
+
+ * "git grep" learned the grep.fullname configuration variable to force
+   "--full-name" to be the default.  This may cause regressions for
+   scripted users who do not expect this new behaviour.
+
+ * "git imap-send" learned to ask the credential helper for auth
+   material.
+
+ * "git log" and friends now understand the value "auto" for the
+   "log.decorate" configuration variable to enable the "--decorate"
+   option automatically when the output is sent to tty.
+
+ * "git merge" without an argument, even when there is an upstream
+   defined for the current branch, refused to run until
+   merge.defaultToUpstream is set to true.  Flip the default of that
+   configuration variable to true.
+
+ * "git mergetool" learned to drive the vimdiff3 backend.
+
+ * mergetool.prompt used to default to 'true', always asking "do you
+   really want to run the tool on this path?".  The default has been
+   changed to 'false'.  However, the prompt will still appear if
+   mergetool used its autodetection system to guess which tool to use.
+   Users who explicitly specify or configure a tool will no longer see
+   the prompt by default.
+
+   Strictly speaking, this is a backward incompatible change and
+   users need to explicitly set the variable to 'true' if they want
+   to be prompted to confirm running the tool on each path.
+
+ * "git replace" learned the "--edit" subcommand to create a
+   replacement by editing an existing object.
+
+ * "git replace" learned a "--graft" option to rewrite the parents of a
+   commit.
+
+ * "git send-email" learned "--to-cover" and "--cc-cover" options, to
+   tell it to copy To: and Cc: headers found in the first input file
+   when emitting later input files.
+
+ * "git svn" learned to cope with malformed timestamps with only one
+   digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted
+   by some broken subversion server implementations.
+
+ * "git tag" when editing the tag message shows the name of the tag
+   being edited as a comment in the editor.
+
+ * "git tag" learned to pay attention to "tag.sort" configuration, to
+   be used as the default sort order when no --sort=<value> option
+   is given.
+
+ * A new "git verify-commit" command, to check GPG signatures in signed
+   commits, in a way similar to "git verify-tag" is used to check
+   signed tags, was added.
+
+
+Performance, Internal Implementation, etc.
+
+ * Build procedure for 'subtree' (in contrib/) has been cleaned up.
+
+ * Support for the profile-feedback build, which has
+   bit-rotted for quite a while, has been updated.
+
+ * An experimental format to use two files (the base file and
+   incremental changes relative to it) to represent the index has been
+   introduced; this may reduce I/O cost of rewriting a large index
+   when only small part of the working tree changes.
+
+ * Effort to shrink the size of patches Windows folks maintain on top
+   by upstreaming them continues.  More tests that are not applicable
+   to the Windows environment are identified and either skipped or
+   made more portable.
+
+ * Eradication of "test $condition -a $condition" from our scripts
+   continues.
+
+ * The `core.deltabasecachelimit` used to default to 16 MiB , but this
+   proved to be too small, and has been bumped to 96 MiB.
+
+ * "git blame" has been optimized greatly by reorganising the data
+   structure that is used to keep track of the work to be done.
+
+ * "git diff" that compares 3-or-more trees (e.g. parents and the
+   result of a merge) has been optimized.
+
+ * The API to update/delete references are being converted to handle
+   updates to multiple references in a transactional way.  As an
+   example, "update-ref --stdin [-z]" has been updated to use this
+   API.
+
+ * skip_prefix() and strip_suffix() API functions are used a lot more
+   widely throughout the codebase now.
+
+ * Parts of the test scripts can be skipped by using a range notation,
+   e.g. "sh t1234-test.sh --run='1-4 6 8-'" to omit test piece 5 and 7
+   and run everything else.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.0
+----------------
+
+Unless otherwise noted, all the fixes since v2.0 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * We used to unconditionally disable the pager in the pager process
+   we spawn to feed out output, but that prevented people who want to
+   run "less" within "less" from doing so.
+   (merge c0459ca je/pager-do-not-recurse later to maint).
+
+ * Tools that read diagnostic output in our standard error stream do
+   not want to see terminal control sequence (e.g. erase-to-eol).
+   Detect them by checking if the standard error stream is connected
+   to a tty.
+   (merge 38de156 mn/sideband-no-ansi later to maint).
+
+ * Mishandling of patterns in .gitignore that have trailing SPs quoted
+   with backslashes (e.g. ones that end with "\ ") has been
+   corrected.
+   (merge 97c1364be6b pb/trim-trailing-spaces later to maint).
+
+ * Reworded the error message given upon a failure to open an existing
+   loose object file due to e.g. permission issues; it was reported as
+   the object being corrupt, but that is not quite true.
+   (merge d6c8a05 jk/report-fail-to-read-objects-better later to maint).
+
+ * "git log -2master" is a common typo that shows two commits starting
+   from whichever random branch that is not 'master' that happens to
+   be checked out currently.
+   (merge e3fa568 jc/revision-dash-count-parsing later to maint).
+
+ * Code to avoid adding the same alternate object store twice was
+   subtly broken for a long time, but nobody seems to have noticed.
+   (merge 80b4785 rs/fix-alt-odb-path-comparison later to maint).
+   (merge 539e750 ek/alt-odb-entry-fix later to maint).
+
+ * The "%<(10,trunc)%s" pretty format specifier in the log family of
+   commands is used to truncate the string to a given length (e.g. 10
+   in the example) with padding to column-align the output, but did
+   not take into account that number of bytes and number of display
+   columns are different.
+   (merge 7d50987 as/pretty-truncate later to maint).
+
+ * "%G" (nothing after G) is an invalid pretty format specifier, but
+   the parser did not notice it as garbage.
+   (merge 958b2eb jk/pretty-G-format-fixes later to maint).
+
+ * A handful of code paths had to read the commit object more than
+   once when showing header fields that are usually not parsed.  The
+   internal data structure to keep track of the contents of the commit
+   object has been updated to reduce the need for this double-reading,
+   and to allow the caller find the length of the object.
+   (merge 218aa3a jk/commit-buffer-length later to maint).
+
+ * The "mailmap.file" configuration option did not support tilde
+   expansion (i.e. ~user/path and ~/path).
+   (merge 9352fd5 ow/config-mailmap-pathname later to maint).
+
+ * The completion scripts (in contrib/) did not know about quite a few
+   options that are common between "git merge" and "git pull", and a
+   couple of options unique to "git merge".
+   (merge 8fee872 jk/complete-merge-pull later to maint).
+
+ * The unix-domain socket used by the sample credential cache daemon
+   tried to unlink an existing stale one at a wrong path, if the path
+   to the socket was given as an overlong path that does not fit in
+   the sun_path member of the sockaddr_un structure.
+   (merge 2869b3e rs/fix-unlink-unix-socket later to maint).
+
+ * An ancient rewrite passed a wrong pointer to a curl library
+   function in a rarely used code path.
+   (merge 479eaa8 ah/fix-http-push later to maint).
+
+ * "--ignore-space-change" option of "git apply" ignored the spaces
+   at the beginning of lines too aggressively, which is inconsistent
+   with the option of the same name that "diff" and "git diff" have.
+   (merge 14d3bb4 jc/apply-ignore-whitespace later to maint).
+
+ * "git blame" miscounted the number of columns needed to show localized
+   timestamps, resulting in a jaggy left-side-edge for the source code
+   lines in its output.
+   (merge dd75553 jx/blame-align-relative-time later to maint).
+
+ * "git blame" assigned the blame to the copy in the working-tree if
+   the repository is set to core.autocrlf=input and the file used CRLF
+   line endings.
+   (merge 4d4813a bc/blame-crlf-test later to maint).
+
+ * "git clone -b brefs/tags/bar" would have mistakenly thought we were
+   following a single tag, even though it was a name of the branch,
+   because it incorrectly used strstr().
+   (merge 60a5f5f jc/fix-clone-single-starting-at-a-tag later to maint).
+
+ * "git commit --allow-empty-message -C $commit" did not work when the
+   commit did not have any log message.
+   (merge 076cbd6 jk/commit-C-pick-empty later to maint).
+
+ * "git diff --find-copies-harder" sometimes pretended as if the mode
+   bits have changed for paths that are marked with the assume-unchanged
+   bit.
+   (merge 5304810 jk/diff-files-assume-unchanged later to maint).
+
+ * "filter-branch" left an empty single-parent commit that results when
+   all parents of a merge commit get mapped to the same commit, even
+   under "--prune-empty".
+   (merge 79bc4ef cb/filter-branch-prune-empty-degenerate-merges later to maint).
+
+ * "git format-patch" did not enforce the rule that the "--follow"
+   option from the log/diff family of commands must be used with
+   exactly one pathspec.
+   (merge dd63f16 jk/diff-follow-must-take-one-pathspec later to maint).
+
+ * "git gc --auto" was recently changed to run in the background to
+   give control back early to the end-user sitting in front of the
+   terminal, but it forgot that housekeeping involving reflogs should
+   be done without other processes competing for accesses to the refs.
+   (merge 62aad18 nd/daemonize-gc later to maint).
+
+ * "git grep -O" to show the lines that hit in the pager did not work
+   well with case insensitive search.  We now spawn "less" with its
+   "-I" option when it is used as the pager (which is the default).
+   (merge f7febbe sk/spawn-less-case-insensitively-from-grep-O-i later to maint).
+
+ * We used to disable threaded "git index-pack" on platforms without
+   thread-safe pread(); use a different workaround for such
+   platforms to allow threaded "git index-pack".
+   (merge 3953949 nd/index-pack-one-fd-per-thread later to maint).
+
+ * The error reporting from "git index-pack" has been improved to
+   distinguish missing objects from type errors.
+   (merge 77583e7 jk/index-pack-report-missing later to maint).
+
+ * "log --show-signature" incorrectly decided the color to paint a
+   mergetag that was and was not correctly validated.
+   (merge 42c55ce mg/fix-log-mergetag-color later to maint).
+
+ * "log --show-signature" did not pay attention to the "--graph" option.
+   (merge cf3983d zk/log-graph-showsig later to maint).
+
+ * "git mailinfo" used to read beyond the ends of header strings while
+   parsing an incoming e-mail message to extract the patch.
+   (merge b1a013d rs/mailinfo-header-cmp later to maint).
+
+ * On a case insensitive filesystem, merge-recursive incorrectly
+   deleted the file that is to be renamed to a name that is the same
+   except for case differences.
+   (merge baa37bf dt/merge-recursive-case-insensitive later to maint).
+
+ * Merging changes into a file that ends in an incomplete line made the
+   last line into a complete one, even when the other branch did not
+   change anything around the end of file.
+   (merge ba31180 mk/merge-incomplete-files later to maint).
+
+ * "git pack-objects" unnecessarily copied the previous contents when
+   extending the hashtable, even though it will populate the table
+   from scratch anyway.
+   (merge fb79947 rs/pack-objects-no-unnecessary-realloc later to maint).
+
+ * Recent updates to "git repack" started to duplicate objects that
+   are in packfiles marked with the .keep flag into the new packfile by
+   mistake.
+   (merge d078d85 jk/repack-pack-keep-objects later to maint).
+
+ * "git rerere forget" did not work well when merge.conflictstyle
+   was set to a non-default value.
+   (merge de3d8bb fc/rerere-conflict-style later to maint).
+
+ * "git remote rm" and "git remote prune" can involve removing many
+   refs at once, which is not a very efficient thing to do when very
+   many refs exist in the packed-refs file.
+   (merge e6bea66 jl/remote-rm-prune later to maint).
+
+ * "git log --exclude=<glob> --all | git shortlog" worked as expected,
+   but "git shortlog --exclude=<glob> --all", which is supposed to be
+   identical to the above pipeline, was not accepted at the command
+   line argument parser level.
+   (merge eb07774 jc/shortlog-ref-exclude later to maint).
+
+ * The autostash mode of "git rebase -i" did not restore the dirty
+   working tree state if the user aborted the interactive rebase by
+   emptying the insn sheet.
+   (merge ddb5432 rr/rebase-autostash-fix later to maint).
+
+ * "git rebase --fork-point" did not filter out patch-identical
+   commits correctly.
+
+ * During "git rebase --merge", a conflicted patch could not be
+   skipped with "--skip" if the next one also conflicted.
+   (merge 95104c7 bc/fix-rebase-merge-skip later to maint).
+
+ * "git show -s" (i.e. show log message only) used to incorrectly emit
+   an extra blank line after a merge commit.
+   (merge ad2f725 mk/show-s-no-extra-blank-line-for-merges later to maint).
+
+ * "git status", even though it is a read-only operation, tries to
+   update the index with refreshed lstat(2) info to optimize future
+   accesses to the working tree opportunistically, but this could
+   race with a "read-write" operation that modifies the index while it
+   is running.  Detect such a race and avoid overwriting the index.
+   (merge 426ddee ym/fix-opportunistic-index-update-race later to maint).
+
+ * "git status" (and "git commit") behaved as if changes in a modified
+   submodule are not there if submodule.*.ignore configuration is set,
+   which was misleading.  The configuration is only to unclutter diff
+   output during the course of development, and not to hide
+   changes in the "status" output to cause the users forget to commit
+   them.
+   (merge c215d3d jl/status-added-submodule-is-never-ignored later to maint).
+
+ * Documentation for "git submodule sync" forgot to say that the subcommand
+   can take the "--recursive" option.
+   (merge 9393ae7 mc/doc-submodule-sync-recurse later to maint).
+
+ * "git update-index --cacheinfo" in 2.0 release crashed on a
+   malformed command line.
+   (merge c8e1ee4 jc/rev-parse-argh-dashed-multi-words later to maint).
+
+ * The mode to run tests with HTTP server tests disabled was broken.
+   (merge afa53fe na/no-http-test-in-the-middle later to maint).

+Git v2.1.1 Release Notes
+========================
+
+ * Git 2.0 had a regression where "git fetch" into a shallowly
+   cloned repository from a repository with bitmap object index
+   enabled did not work correctly.  This has been corrected.
+
+ * Git 2.0 had a regression which broke (rarely used) "git diff-tree
+   -t".  This has been corrected.
+
+ * "git log --pretty/format=" with an empty format string did not
+   mean the more obvious "No output whatsoever" but "Use default
+   format", which was counterintuitive.  Now it means "nothing shown
+   for the log message part".
+
+ * "git -c section.var command" and "git -c section.var= command"
+   should pass the configuration differently (the former should be a
+   boolean true, the latter should be an empty string), but they
+   didn't work that way.  Now it does.
+
+ * Applying a patch not generated by Git in a subdirectory used to
+   check the whitespace breakage using the attributes for incorrect
+   paths. Also whitespace checks were performed even for paths
+   excluded via "git apply --exclude=<path>" mechanism.
+
+ * "git bundle create" with date-range specification were meant to
+   exclude tags outside the range, but it did not work correctly.
+
+ * "git add x" where x that used to be a directory has become a
+   symbolic link to a directory misbehaved.
+
+ * The prompt script checked $GIT_DIR/ref/stash file to see if there
+   is a stash, which was a no-no.
+
+ * "git checkout -m" did not switch to another branch while carrying
+   the local changes forward when a path was deleted from the index.
+
+ * With sufficiently long refnames, fast-import could have overflown
+   an on-stack buffer.
+
+ * After "pack-refs --prune" packed refs at the top-level, it failed
+   to prune them.
+
+ * "git gc --auto" triggered from "git fetch --quiet" was not quiet.

+========================
+
+ * "git push" over HTTP transport had an artificial limit on number of
+   refs that can be pushed imposed by the command line length.
+
+ * When receiving an invalid pack stream that records the same object
+   twice, multiple threads got confused due to a race.

+ * Some MUAs mangled a line in a message that begins with "From " to
+   ">From " when writing to a mailbox file and feeding such an input to
+   "git am" used to lose such a line.
+
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly
+   use the hostname even when gethostbyname() reported that the given
+   hostname is not found.
+
+ * Newer versions of 'meld' breaks the auto-detection we use to see if
+   they are new enough to support the `--output` option.
+
+ * "git pack-objects" forgot to disable the codepath to generate
+   object recheability bitmap when it needs to split the resulting
+   pack.
+
+ * "gitweb" used deprecated CGI::startfrom, which was removed from
+   CGI.pm as of 4.04; use CGI::start_from instead.
+
+ * "git log" documentation had an example section marked up not
+   quite correctly, which passed AsciiDoc but failed with
+   AsciiDoctor.
+
+Also contains some documentation updates.

+Git v2.1.4 Release Notes
+========================
+
+Fixes since v2.1.3
+------------------
+
+ * We used to allow committing a path ".Git/config" with Git that is
+   running on a case sensitive filesystem, but an attempt to check out
+   such a path with Git that runs on a case insensitive filesystem
+   would have clobbered ".git/config", which is definitely not what
+   the user would have expected.  Git now prevents you from tracking
+   a path with ".Git" (in any case combination) as a path component.
+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.2 Release Notes
+======================
+
+Updates since v2.1
+------------------
+
+Ports
+
+ * Building on older MacOS X systems automatically sets
+   the necessary NO_APPLE_COMMON_CRYPTO build-time option.
+
+ * Building with NO_PTHREADS has been resurrected.
+
+ * Compilation options have been updated a bit to better support the
+   z/OS port.
+
+
+UI, Workflows & Features
+
+ * "git archive" learned to filter what gets archived with a pathspec.
+
+ * "git config --edit --global" starts from a skeletal per-user
+   configuration file contents, instead of a total blank, when the
+   user does not already have any global config.  This immediately
+   reduces the need to later ask "Have you forgotten to set
+   core.user?", and we can add more to the template as we gain
+   more experience.
+
+ * "git stash list -p" used to be almost always a no-op because each
+   stash entry is represented as a merge commit.  It learned to show
+   the difference between the base commit version and the working tree
+   version, which is in line with what "git stash show" gives.
+
+ * Sometimes users want to report a bug they experience on their
+   repository, but they are not at liberty to share the contents of
+   the repository.  "fast-export" was taught an "--anonymize" option
+   to replace blob contents, names of people, paths and log
+   messages with bland and simple strings to help them.
+
+ * "git difftool" learned an option to stop feeding paths to the
+   diff backend when it exits with a non-zero status.
+
+ * "git grep" learned to paint (or not paint) partial matches on
+   context lines when showing "grep -C<num>" output in color.
+
+ * "log --date=iso" uses a slight variant of the ISO 8601 format that is
+   more human readable.  A new "--date=iso-strict" option gives
+   datetime output that conforms more strictly.
+
+ * The logic "git prune" uses is more resilient against various corner
+   cases.
+
+ * A broken reimplementation of Git could write an invalid index that
+   records both stage #0 and higher-stage entries for the same path.
+   We now notice and reject such an index, as there is no sensible
+   fallback (we do not know if the broken tool wanted to resolve and
+   forgot to remove the higher-stage entries, or if it wanted to unresolve
+   and forgot to remove the stage #0 entry).
+
+ * The temporary files "git mergetool" uses are renamed to avoid too
+   many dots in them (e.g. a temporary file for "hello.c" used to be
+   named e.g. "hello.BASE.4321.c" but now uses underscore instead,
+   e.g. "hello_BASE_4321.c", to allow us to have multiple variants).
+
+ * The temporary files "git mergetool" uses can be placed in a newly
+   created temporary directory, instead of the current directory, by
+   setting the mergetool.writeToTemp configuration variable.
+
+ * "git mergetool" understands "--tool bc" now, as version 4 of
+   BeyondCompare can be driven the same way as its version 3 and it
+   feels awkward to say "--tool bc3" to run version 4.
+
+ * The "pre-receive" and "post-receive" hooks are no longer required
+   to consume their input fully (not following this requirement used
+   to result in intermittent errors in "git push").
+
+ * The pretty-format specifier "%d", which expands to " (tagname)"
+   for a tagged commit, gained a cousin "%D" that just gives the
+   "tagname" without frills.
+
+ * "git push" learned "--signed" push, that allows a push (i.e.
+   request to update the refs on the other side to point at a new
+   history, together with the transmission of necessary objects) to be
+   signed, so that it can be verified and audited, using the GPG
+   signature of the person who pushed, that the tips of branches at a
+   public repository really point the commits the pusher wanted to,
+   without having to "trust" the server.
+
+ * "git interpret-trailers" is a new filter to programmatically edit
+   the tail end of the commit log messages, e.g. "Signed-off-by:".
+
+ * "git help everyday" shows the "Everyday Git in 20 commands or so"
+   document, whose contents have been updated to match more modern
+   Git practice.
+
+ * On the "git svn" front, work progresses to reduce memory consumption and
+   to improve handling of mergeinfo.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * The API to manipulate the "refs" has been restructured to make it
+   more transactional, with the eventual goal to allow all-or-none
+   atomic updates and migrating the storage to something other than
+   the traditional filesystem based one (e.g. databases).
+
+ * The lockfile API and its users have been cleaned up.
+
+ * We no longer attempt to keep track of individual dependencies to
+   the header files in the build procedure, relying instead on automated
+   dependency generation support from modern compilers.
+
+ * In tests, we have been using NOT_{MINGW,CYGWIN} test prerequisites
+   long before negated prerequisites e.g. !MINGW were invented.
+   The former has been converted to the latter to avoid confusion.
+
+ * Optimized looking up a remote's configuration in a repository with very many
+   remotes defined.
+
+ * There are cases where you lock and open to write a file, close it
+   to show the updated contents to an external processes, and then have
+   to update the file again while still holding the lock; now the
+   lockfile API has support for such an access pattern.
+
+ * The API to allocate the structure to keep track of commit
+   decoration has been updated to make it less cumbersome to use.
+
+ * An in-core caching layer to let us avoid reading the same
+   configuration files several times has been added.  A few commands
+   have been converted to use this subsystem.
+
+ * Various code paths have been cleaned up and simplified by using
+   the "strbuf", "starts_with()", and "skip_prefix()" APIs more.
+
+ * A few codepaths that died when large blobs that would not fit in
+   core are involved in their operation have been taught to punt
+   instead, by e.g. marking a too-large blob as not to be diffed.
+
+ * A few more code paths in "commit" and "checkout" have been taught
+   to repopulate the cache-tree in the index, to help speed up later
+   "write-tree" (used in "commit") and "diff-index --cached" (used in
+   "status").
+
+ * A common programming mistake to assign the same short option name
+   to two separate options is detected by the parse_options() API to help
+   developers.
+
+ * The code path to write out the packed-refs file has been optimized,
+   which especially matters in a repository with a large number of
+   refs.
+
+ * The check to see if a ref $F can be created by making sure no
+   existing ref has $F/ as its prefix has been optimized, which
+   especially matters in a repository with a large number of existing
+   refs.
+
+ * "git fsck" was taught to check the contents of tag objects a bit more.
+
+ * "git hash-object" was taught a "--literally" option to help
+   debugging.
+
+ * When running a required clean filter, we do not have to mmap the
+   original before feeding the filter.  Instead, stream the file
+   contents directly to the filter and process its output.
+
+ * The scripts in the test suite can be run with the "-x" option to show
+   a shell-trace of each command they run.
+
+ * The "run-command" API learned to manage the argv and environment
+   arrays for child process, alleviating the need for the callers to
+   allocate and deallocate them.
+
+ * Some people use AsciiDoctor, instead of AsciiDoc, to format our
+   documentation set; the documentation has been adjusted to be usable
+   by both, as AsciiDoctor is pickier than AsciiDoc about its input
+   mark-up.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.1
+----------------
+
+Unless otherwise noted, all the fixes since v2.1 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git log --pretty/format=" with an empty format string did not
+   mean the more obvious "No output whatsoever" but "Use default
+   format", which was counterintuitive.
+
+ * "git -c section.var command" and "git -c section.var= command"
+   should pass the configuration value differently (the former should be a
+   boolean true, the latter should be an empty string).
+
+ * Applying a patch not generated by Git in a subdirectory used to
+   check for whitespace breakage using the attributes of incorrect
+   paths. Also whitespace checks were performed even for paths
+   excluded via the "git apply --exclude=<path>" mechanism.
+
+ * "git bundle create" with a date-range specification was meant to
+   exclude tags outside the range, but it didn't.
+
+ * "git add x" where x used to be a directory and is now a
+   symbolic link to a directory misbehaved.
+
+ * The prompt script checked the $GIT_DIR/ref/stash file to see if there
+   is a stash, which was a no-no.
+
+ * Pack-protocol documentation had a minor typo.
+
+ * "git checkout -m" did not switch to another branch while carrying
+   the local changes forward when a path was deleted from the index.
+
+ * "git daemon" (with NO_IPV6 build configuration) used to incorrectly
+   use the hostname even when gethostbyname() reported that the given
+   hostname is not found.
+   (merge 107efbe rs/daemon-fixes later to maint).
+
+ * With sufficiently long refnames, "git fast-import" could have
+   overflowed an on-stack buffer.
+
+ * After "pack-refs --prune" packed refs at the top-level, it failed
+   to prune them.
+
+ * Progress output from "git gc --auto" was visible in "git fetch -q".
+
+ * We used to pass -1000 to poll(2), expecting it to also mean "no
+   timeout", which should be spelled as -1.
+
+ * "git rebase" documentation was unclear that it is required to
+   specify on what <upstream> the rebase is to be done when telling it
+   to first check out <branch>.
+   (merge 95c6826 so/rebase-doc later to maint).
+
+ * "git push" over HTTP transport had an artificial limit on the number of
+   refs that can be pushed, imposed by the command line length.
+   (merge 26be19b jk/send-pack-many-refspecs later to maint).
+
+ * When receiving an invalid pack stream that records the same object
+   twice, multiple threads got confused due to a race.
+   (merge ab791dd jk/index-pack-threading-races later to maint).
+
+ * An attempt to remove the entire tree in the "git fast-import" input
+   stream caused it to misbehave.
+   (merge 2668d69 mb/fast-import-delete-root later to maint).
+
+ * Reachability check (used in "git prune" and friends) did not add a
+   detached HEAD as a starting point to traverse objects still in use.
+   (merge c40fdd0 mk/reachable-protect-detached-head later to maint).
+
+ * "git config --add section.var val" when section.var already has an
+   empty-string value used to lose the empty-string value.
+   (merge c1063be ta/config-add-to-empty-or-true-fix later to maint).
+
+ * "git fsck" failed to report that it found corrupt objects via its
+   exit status in some cases.
+   (merge 30d1038 jk/fsck-exit-code-fix later to maint).
+
+ * Use of the "--verbose" option used to break "git branch --merged".
+   (merge 12994dd jk/maint-branch-verbose-merged later to maint).
+
+ * Some MUAs mangle a line in a message that begins with "From " to
+   ">From " when writing to a mailbox file, and feeding such an input
+   to "git am" used to lose such a line.
+   (merge 85de86a jk/mbox-from-line later to maint).
+
+ * "rev-parse --verify --quiet $name" is meant to quietly exit with a
+   non-zero status when $name is not a valid object name, but still
+   gave error messages in some cases.
+
+ * A handful of C source files have been updated to include
+   "git-compat-util.h" as the first thing, to conform better to our
+   coding guidelines.
+   (merge 1c4b660 da/include-compat-util-first-in-c later to maint).
+
+ * The t7004 test, which tried to run Git with small stack space, has been
+   updated to use a bit larger stack to avoid false breakage on some
+   platforms.
+   (merge b9a1907 sk/tag-contains-wo-recursion later to maint).
+
+ * A few documentation pages had example sections marked up not quite
+   correctly, which passed AsciiDoc but failed with AsciiDoctor.
+   (merge c30c43c bc/asciidoc-pretty-formats-fix later to maint).
+   (merge f8a48af bc/asciidoc later to maint).
+
+ * "gitweb" used deprecated CGI::startfrom, which was removed from
+   CGI.pm as of 4.04; use CGI::start_from instead.
+   (merge 4750f4b rm/gitweb-start-form later to maint).
+
+ * Newer versions of 'meld' break the auto-detection we use to see if
+   they are new enough to support the `--output` option.
+   (merge b12d045 da/mergetool-meld later to maint).
+
+ * "git pack-objects" forgot to disable the codepath to generate the
+   object reachability bitmap when it needs to split the resulting
+   pack.
+   (merge 2113471 jk/pack-objects-no-bitmap-when-splitting later to maint).
+
+ * The code to use cache-tree trusted the on-disk data too much and
+   fell into an infinite loop upon seeing an incorrectly recorded
+   index file.
+   (merge 729dbbd jk/cache-tree-protect-from-broken-libgit2 later to maint).
+
+ * "git fetch" into a repository where branch B was deleted earlier,
+   back when it had reflog enabled, and then branch B/C is fetched
+   into it without reflog enabled, which is arguably an unlikely
+   corner case, unnecessarily failed.
+   (merge aae828b jk/fetch-reflog-df-conflict later to maint).
+
+ * "git log --first-parent -L..." used to crash.
+   (merge a8787c5 tm/line-log-first-parent later to maint).

+   running on a case sensitive filesystem, but an attempt to check out

+   would have clobbered ".git/config", which is definitely not what

+
+ * On Windows, certain path components that are different from ".git"
+   are mapped to ".git", e.g. "git~1/config" is treated as if it were
+   ".git/config".  HFS+ has a similar issue, where certain unicode
+   codepoints are ignored, e.g. ".g\u200cit/config" is treated as if
+   it were ".git/config".  Pathnames with these potential issues are
+   rejected on the affected systems.  Git on systems that are not
+   affected by this issue (e.g. Linux) can also be configured to
+   reject them to ensure cross platform interoperability of the hosted
+   projects.
+
+ * "git fsck" notices a tree object that records such a path that can
+   be confused with ".git", and with receive.fsckObjects configuration
+   set to true, an attempt to "git push" such a tree object will be
+   rejected.  Such a path may not be a problem on a well behaving
+   filesystem but in order to protect those on HFS+ and on case
+   insensitive filesystems, this check is enabled on all platforms.
+
+A big "thanks!" for bringing this issue to us goes to our friends in
+the Mercurial land, namely, Matt Mackall and Augie Fackler.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.2.2 Release Notes
+========================
+
+Fixes since v2.2.1
+------------------
+
+ * "git checkout $treeish $path", when $path in the index and the
+   working tree already matched what is in $treeish at the $path,
+   still overwrote the $path unnecessarily.
+
+ * "git config --get-color" did not parse its command line arguments
+   carefully.
+
+ * open() emulated on Windows platforms did not give EISDIR upon
+   an attempt to open a directory for writing.
+
+ * A few code paths used abs() when they should have used labs() on
+   long integers.
+
+ * "gitweb" used to depend on a behaviour recent CGI.pm deprecated.
+
+ * "git init" (hence "git clone") initialized the per-repository
+   configuration file .git/config with x-bit by mistake.
+
+ * Git 2.0 was supposed to make the "simple" mode for the default of
+   "git push", but it didn't.
+
+ * "Everyday" document had a broken link.
+
+ * The build procedure did not bother fixing perl and python scripts
+   when NO_PERL and NO_PYTHON build-time configuration changed.
+
+ * The code that reads the reflog from the newer to the older entries
+   did not handle an entry that crosses a boundary of block it uses to
+   read them correctly.
+
+ * "git apply" was described in the documentation to take --ignore-date
+   option, which it does not.
+
+ * Traditionally we tried to avoid interpreting date strings given by
+   the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
+   used early November 2014 was taken as "October 12, 2014" because it
+   is likely that a date in the future, December 10, is a mistake.
+   This heuristics has been loosened to allow people to express future
+   dates (most notably, --until=<date> may want to be far in the
+   future) and we no longer tiebreak by future-ness of the date when
+
+    (1) ISO-like format is used, and
+    (2) the string can make sense interpreted as both y-m-d and y-d-m.
+
+   Git may still have to use the heuristics to tiebreak between dd/mm/yy
+   and mm/dd/yy, though.
+
+ * The code to abbreviate an object name to its short unique prefix
+   has been optimized when no abbreviation was requested.
+
+ * "git add --ignore-errors ..." did not ignore an error to
+   give a file that did not exist.
+
+ * Git did not correctly read an overlong refname from a packed refs
+   file.

+Git v2.3 Release Notes
+======================
+
+This one ended up to be a release with lots of small corrections and
+improvements without big uncomfortably exciting features.  The recent
+security fix that went to 2.2.1 and older maintenance tracks is also
+contained in this update.
+
+
+Updates since v2.2
+------------------
+
+Ports
+
+ * Recent gcc toolchain on Cygwin started throwing compilation warning,
+   which has been squelched.
+
+ * A few updates to build on platforms that lack tv_nsec,
+   clock_gettime, CLOCK_MONOTONIC and HMAC_CTX_cleanup (e.g. older
+   RHEL) have been added.
+
+
+UI, Workflows & Features
+
+ * It was cumbersome to use "GIT_SSH" mechanism when the user wanted
+   to pass an extra set of arguments to the underlying ssh.  A new
+   environment variable GIT_SSH_COMMAND can be used for this.
+
+ * A request to store an empty note via "git notes" meant to remove
+   note from the object but with --allow-empty we will store a
+   (surprise!)  note that is empty.
+
+ * "git interpret-trailers" learned to properly handle the
+   "Conflicts:" block at the end.
+
+ * "git am" learned "--message-id" option to copy the message ID of
+   the incoming e-mail to the log message of resulting commit.
+
+ * "git clone --reference=<over there>" learned the "--dissociate"
+   option to go with it; it borrows objects from the reference object
+   store while cloning only to reduce network traffic and then
+   dissociates the resulting clone from the reference by performing
+   local copies of borrowed objects.
+
+ * "git send-email" learned "--transfer-encoding" option to force a
+   non-fault Content-Transfer-Encoding header (e.g. base64).
+
+ * "git send-email" normally identifies itself via X-Mailer: header in
+   the message it sends out.  A new command line flag --no-xmailer
+   allows the user to squelch the header.
+
+ * "git push" into a repository with a working tree normally refuses
+   to modify the branch that is checked out.  The command learned to
+   optionally do an equivalent of "git reset --hard" only when there
+   is no change to the working tree and the index instead, which would
+   be useful to "deploy" by pushing into a repository.
+
+ * "git new-workdir" (in contrib/) can be used to populate an empty
+   and existing directory now.
+
+ * Credential helpers are asked in turn until one of them give
+   positive response, which is cumbersome to turn off when you need to
+   run Git in an automated setting.  The credential helper interface
+   learned to allow a helper to say "stop, don't ask other helpers."
+   Also GIT_TERMINAL_PROMPT environment can be set to false to disable
+   our built-in prompt mechanism for passwords.
+
+ * "git branch -d" (delete) and "git branch -m" (move) learned to
+   honor "-f" (force) flag; unlike many other subcommands, the way to
+   force these have been with separate "-D/-M" options, which was
+   inconsistent.
+
+ * "diff-highlight" filter (in contrib/) allows its color output to be
+   customized via configuration variables.
+
+ * "git imap-send" learned to take "-v" (verbose) and "-q" (quiet)
+   command line options.
+
+ * "git remote add $name $URL" is now allowed when "url.$URL.insteadOf"
+   is already defined.
+
+ * "git imap-send" now can be built to use cURL library to talk to
+   IMAP servers (if the library is recent enough, of course).
+   This allows you to use authenticate method other than CRAM-MD5,
+   among other things.
+
+ * "git imap-send" now allows GIT_CURL_VERBOSE environment variable to
+   control the verbosity when talking via the cURL library.
+
+ * The prompt script (in contrib/) learned to optionally hide prompt
+   when in an ignored directory by setting GIT_PS1_HIDE_IF_PWD_IGNORED
+   shell variable.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Earlier we made "rev-list --object-edge" more aggressively list the
+   objects at the edge commits, in order to reduce number of objects　
+   fetched into a shallow repository, but the change affected cases
+   other than "fetching into a shallow repository" and made it
+   unusably slow (e.g. fetching into a normal repository should not
+   have to suffer the overhead from extra processing).  Limit it to a
+   more specific case by introducing --objects-edge-aggressive, a new
+   option to rev-list.
+
+ * Squelched useless compiler warnings on Mac OS X regarding the
+   crypto API.
+
+ * The procedure to generate unicode table has been simplified.
+
+ * Some filesystems assign filemodes in a strange way, fooling then
+   automatic "filemode trustability" check done during a new
+   repository creation.  The initialization codepath has been hardened
+   against this issue.
+
+ * The codepath in "git remote update --prune" to drop many refs has
+   been optimized.
+
+ * The API into get_merge_bases*() family of functions was easy to
+   misuse, which has been corrected to make it harder to do so.
+
+ * Long overdue departure from the assumption that S_IFMT is shared by
+   everybody made in 2005, which was necessary to port to z/OS.
+
+ * "git push" and "git fetch" did not communicate an overlong refname
+   correctly.  Now it uses 64kB sideband to accommodate longer ones.
+
+ * Recent GPG changes the keyring format and drops support for RFC1991
+   formatted signatures, breaking our existing tests.
+
+ * "git-prompt" (in contrib/) used a variable from the global scope,
+   possibly contaminating end-user's namespace.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.2
+----------------
+
+Unless otherwise noted, all the fixes since v2.2 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git http-push" over WebDAV (aka dumb http-push) was broken in
+   v2.2.2 when parsing a symbolic ref, resulting in a bogus request
+   that gets rejected by recent versions of cURL library.
+   (merge f6786c8 jk/http-push-symref-fix later to maint).
+
+ * The logic in "git bisect bad HEAD" etc. to avoid forcing the test
+   of the common ancestor of bad and good commits was broken.
+   (merge 07913d5 cc/bisect-rev-parsing later to maint).
+
+ * "git checkout-index --temp=$target $path" did not work correctly
+   for paths outside the current subdirectory in the project.
+   (merge 74c4de5 es/checkout-index-temp later to maint).
+
+ * The report from "git checkout" on a branch that builds on another
+   local branch by setting its branch.*.merge to branch name (not a
+   full refname) incorrectly said that the upstream is gone.
+   (merge 05e7368 jc/checkout-local-track-report later to maint).
+
+ * With The git-prompt support (in contrib/), using the exit status of
+   the last command in the prompt, e.g.  PS1='$(__git_ps1) $? ', did
+   not work well, because the helper function stomped on the exit
+   status.
+   (merge 6babe76 tf/prompt-preserve-exit-status later to maint).
+
+ * Recent update to "git commit" broke amending an existing commit
+   with bogus author/committer lines without a valid e-mail address.
+   (merge c83a509 jk/commit-date-approxidate later to maint).
+
+ * The lockfile API used to get confused which file to clean up when
+   the process moved the $cwd after creating a lockfile.
+   (merge fa137f6 nd/lockfile-absolute later to maint).
+
+ * Traditionally we tried to avoid interpreting date strings given by
+   the user as future dates, e.g. GIT_COMMITTER_DATE=2014-12-10 when
+   used early November 2014 was taken as "October 12, 2014" because it
+   is likely that a date in the future, December 10, is a mistake.
+   This heuristics has been loosened to allow people to express future
+   dates (most notably, --until=<date> may want to be far in the
+   future) and we no longer tiebreak by future-ness of the date when
+
+    (1) ISO-like format is used, and
+    (2) the string can make sense interpreted as both y-m-d and y-d-m.
+
+   Git may still have to use the heuristics to tiebreak between dd/mm/yy
+   and mm/dd/yy, though.
+   (merge d372395 jk/approxidate-avoid-y-d-m-over-future-dates later to maint).
+
+ * Git did not correctly read an overlong refname from a packed refs
+   file.
+   (merge ea41783 jk/read-packed-refs-without-path-max later to maint).
+
+ * "git apply" was described in the documentation to take --ignore-date
+   option, which it does not.
+   (merge 0cef4e7 rw/apply-does-not-take-ignore-date later to maint).
+
+ * "git add -i" did not notice when the interactive command input
+   stream went away and kept asking the same question.
+   (merge a8bec7a jk/add-i-read-error later to maint).
+
+ * "git send-email" did not handle RFC 2047 encoded headers quite
+   right.
+   (merge ab47e2a rd/send-email-2047-fix later to maint).
+
+ * New tag object format validation added in 2.2 showed garbage after
+   a tagname it reported in its error message.
+   (merge a1e920a js/fsck-tag-validation later to maint).
+
+ * The code that reads the reflog from the newer to the older entries
+   did not handle an entry that crosses a boundary of block it uses to
+   read them correctly.
+   (merge 69216bf jk/for-each-reflog-ent-reverse later to maint).
+
+ * "git diff -B -M" after making a new copy B out of an existing file
+   A and then editing A extensively ought to report that B was created
+   by copying A and A was modified, which is what "git diff -C"
+   reports, but it instead said A was renamed to B and A was edited
+   heavily in place.  This was not just incoherent but also failed to
+   apply with "git apply".  The report has been corrected to match what
+   "git diff -C" produces for this case.
+   (merge 6936b58 jc/diff-b-m later to maint).
+
+ * In files we pre-populate for the user to edit with commented hints,
+   a line of hint that is indented with a tab used to show as '#' (or
+   any comment char), ' ' (space), and then the hint text that began
+   with the tab, which some editors flag as an indentation error (tab
+   following space).  We now omit the space after the comment char in
+   such a case.
+   (merge d55aeb7 jc/strbuf-add-lines-avoid-sp-ht-sequence later to maint).
+
+ * "git ls-tree" does not support path selection based on negative
+   pathspecs, but did not error out when negative pathspecs are given.
+   (merge f1f6224 nd/ls-tree-pathspec later to maint).
+
+ * The function sometimes returned a non-freeable memory and some
+   other times returned a piece of memory that must be freed, leading
+   to inevitable leaks.
+   (merge 59362e5 jc/exec-cmd-system-path-leak-fix later to maint).
+
+ * The code to abbreviate an object name to its short unique prefix
+   has been optimized when no abbreviation was requested.
+   (merge 61e704e mh/find-uniq-abbrev later to maint).
+
+ * "git add --ignore-errors ..." did not ignore an error to
+   give a file that did not exist.
+   (merge 1d31e5a mg/add-ignore-errors later to maint).
+
+ * "git checkout $treeish $path", when $path in the index and the
+   working tree already matched what is in $treeish at the $path,
+   still overwrote the $path unnecessarily.
+   (merge c5326bd jk/checkout-from-tree later to maint).
+
+ * "git config --get-color" did not parse its command line arguments
+   carefully.
+   (merge cb35722 jk/colors-fix later to maint).
+
+ * open() emulated on Windows platforms did not give EISDIR upon
+   an attempt to open a directory for writing.
+   (merge ba6fad0 js/windows-open-eisdir-error later to maint).
+
+ * A few code paths used abs() when they should have used labs() on
+   long integers.
+   (merge 83915ba rs/maint-config-use-labs later to maint).
+   (merge 31a8aa1 rs/receive-pack-use-labs later to maint).
+
+ * "gitweb" used to depend on a behaviour recent CGI.pm deprecated.
+   (merge 13dbf46 jk/gitweb-with-newer-cgi-multi-param later to maint).
+
+ * "git init" (hence "git clone") initialized the per-repository
+   configuration file .git/config with x-bit by mistake.
+   (merge 1f32ecf mh/config-flip-xbit-back-after-checking later to maint).
+
+ * Recent update in Git 2.2 started creating objects/info/packs and
+   info/refs files with permission bits tighter than user's umask.
+   (merge d91175b jk/prune-packed-server-info later to maint).
+
+ * Git 2.0 was supposed to make the "simple" mode for the default of
+   "git push", but it didn't.
+   (merge 00a6fa0 jk/push-simple later to maint).
+
+ * "Everyday" document had a broken link.
+   (merge 366c8d4 po/everyday-doc later to maint).
+
+ * A few test fixes.
+   (merge 880ef58 jk/no-perl-tests later to maint).
+
+ * The build procedure did not bother fixing perl and python scripts
+   when NO_PERL and NO_PYTHON build-time configuration changed.
+   (merge ca2051d jk/rebuild-perl-scripts-with-no-perl-seting-change later to maint).
+
+ * The usage string of "git log" command was marked incorrectly for
+   l10n.
+   (merge e66dc0c km/log-usage-string-i18n later to maint).
+
+ * "git for-each-ref" mishandled --format="%(upstream:track)" when a
+   branch is marked to have forked from a non-existing branch.
+   (merge b6160d9 rc/for-each-ref-tracking later to maint).

+Git v2.3.1 Release Notes
+========================
+
+Fixes since v2.3
+----------------
+
+ * The interactive "show a list and let the user choose from it"
+   interface "add -i" used showed and prompted to the user even when
+   the candidate list was empty, against which the only "choice" the
+   user could have made was to choose nothing.
+
+ * "git apply --whitespace=fix" used to under-allocate the memory
+   when the fix resulted in a longer text than the original patch.
+
+ * "git log --help" used to show rev-list options that are irrelevant
+   to the "log" command.
+
+ * The error message from "git commit", when a non-existing author
+   name was given as value to the "--author=" parameter, has been
+   reworded to avoid misunderstanding.
+
+ * A broken pack .idx file in the receiving repository prevented the
+   dumb http transport from fetching a good copy of it from the other
+   side.
+
+ * The documentation incorrectly said that C(opy) and R(ename) are the
+   only ones that can be followed by the score number in the output in
+   the --raw format.
+
+ * Fix a misspelled conditional that is always true.
+
+ * Code to read branch name from various files in .git/ directory
+   would have misbehaved if the code to write them left an empty file.
+
+ * The "git push" documentation made the "--repo=<there>" option
+   easily misunderstood.
+
+ * After attempting and failing a password-less authentication
+   (e.g. kerberos), libcURL refuses to fall back to password based
+   Basic authentication without a bit of help/encouragement.
+
+ * Setting diff.submodule to 'log' made "git format-patch" produce
+   broken patches.
+
+ * "git rerere" (invoked internally from many mergy operations) did
+   not correctly signal errors when told to update the working tree
+   files and failed to do so for whatever reason.
+
+ * "git blame HEAD -- missing" failed to correctly say "HEAD" when it
+   tried to say "No such path 'missing' in HEAD".
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+Git v2.3.10 Release Notes
+=========================
+
+Fixes since v2.3.9
+------------------
+
+ * xdiff code we use to generate diffs is not prepared to handle
+   extremely large files.  It uses "int" in many places, which can
+   overflow if we have a very large number of lines or even bytes in
+   our input files, for example.  Cap the input size to soemwhere
+   around 1GB for now.
+
+ * Some protocols (like git-remote-ext) can execute arbitrary code
+   found in the URL.  The URLs that submodules use may come from
+   arbitrary sources (e.g., .gitmodules files in a remote
+   repository), and can hurt those who blindly enable recursive
+   fetch.  Restrict the allowed protocols to well known and safe
+   ones.

+Git v2.3.2 Release Notes
+========================
+
+Fixes since v2.3.1
+------------------
+
+ * "update-index --refresh" used to leak when an entry cannot be
+   refreshed for whatever reason.
+
+ * "git fast-import" used to crash when it could not close and
+   conclude the resulting packfile cleanly.
+
+ * "git blame" died, trying to free an uninitialized piece of memory.
+
+ * "git merge-file" did not work correctly in a subdirectory.
+
+ * "git submodule add" failed to squash "path/to/././submodule" to
+   "path/to/submodule".
+
+ * In v2.2.0, we broke "git prune" that runs in a repository that
+   borrows from an alternate object store.
+
+ * Certain older vintages of cURL give irregular output from
+   "curl-config --vernum", which confused our build system.
+
+ * An earlier workaround to squelch unhelpful deprecation warnings
+   from the compiler on Mac OSX unnecessarily set minimum required
+   version of the OS, which the user might want to raise (or lower)
+   for other reasons.
+
+ * Longstanding configuration variable naming rules has been added to
+   the documentation.
+
+ * The credential helper for Windows (in contrib/) used to mishandle
+   a user name with an at-sign in it.
+
+ * Older GnuPG implementations may not correctly import the keyring
+   material we prepare for the tests to use.
+
+ * Clarify in the documentation that "remote.<nick>.pushURL" and
+   "remote.<nick>.URL" are there to name the same repository accessed
+   via different transports, not two separate repositories.
+
+ * The pack bitmap support did not build with older versions of GCC.
+
+ * Reading configuration from a blob object, when it ends with a lone
+   CR, use to confuse the configuration parser.
+
+ * We didn't format an integer that wouldn't fit in "int" but in
+   "uintmax_t" correctly.
+
+ * "git push --signed" gave an incorrectly worded error message when
+   the other side did not support the capability.
+
+ * "git fetch" over a remote-helper that cannot respond to "list"
+   command could not fetch from a symbolic reference e.g. HEAD.
+
+ * The insn sheet "git rebase -i" creates did not fully honor
+   core.abbrev settings.
+
+ * The tests that wanted to see that file becomes unreadable after
+   running "chmod a-r file", and the tests that wanted to make sure it
+   is not run as root, we used "can we write into the / directory?" as
+   a cheap substitute, but on some platforms that is not a good
+   heuristics.  The tests and their prerequisites have been updated to
+   check what they really require.
+
+ * The configuration variable 'mailinfo.scissors' was hard to
+   discover in the documentation.
+
+ * Correct a breakage to git-svn around v2.2 era that triggers
+   premature closing of FileHandle.
+
+ * Even though we officially haven't dropped Perl 5.8 support, the
+   Getopt::Long package that came with it does not support "--no-"
+   prefix to negate a boolean option; manually add support to help
+   people with older Getopt::Long package.
+
+Also contains typofixes, documentation updates and trivial code clean-ups.

+ * The borrowed code in kwset API did not follow our usual convention
+   to use "unsigned char" to store values that range from 0-255.
+
+ * Description given by "grep -h" for its --exclude-standard option
+   was phrased poorly.

+   to override it.
+
+ * "git diff --shortstat --dirstat=changes" showed a dirstat based on
+   lines that was never asked by the end user in addition to the
+   dirstat that the user asked for.
+
+ * The interaction between "git submodule update" and the
+   submodule.*.update configuration was not clearly documented.
+
+ * "git apply" was not very careful about reading from, removing,
+   updating and creating paths outside the working tree (under
+   --index/--cached) or the current directory (when used as a
+   replacement for GNU patch).
+
+ * "git daemon" looked up the hostname even when "%CH" and "%IP"
+   interpolations are not requested, which was unnecessary.
+
+ * The "interpolated-path" option of "git daemon" inserted any string
+   client declared on the "host=" capability request without checking.

+   status, we spawned the pager regardless.  Stop doing that.
+
+ * Recommend format-patch and send-email for those who want to submit

+
+ * An failure early in the "git clone" that started creating the

+   and files left without getting cleaned up.
+
+ * "git fetch" that fetches a commit using the allow-tip-sha1-in-want
+   extension could have failed to fetch all the requested refs.
+
+ * The split-index mode introduced at v2.3.0-rc0~41 was broken in the
+   codepath to protect us against a broken reimplementation of Git
+   that writes an invalid index with duplicated index entries, etc.
+
+ * "git prune" used to largely ignore broken refs when deciding which

+   damage and make it a larger one.
+
+ * "git tag -h" used to show the "--column" and "--sort" options

+========================
+
+Fixes since v2.3.8
+------------------
+
+ * A handful of codepaths that used to use fixed-sized arrays to hold
+   pathnames have been corrected to use strbuf and other mechanisms to

+Git 2.4 Release Notes
+=====================
+
+Backward compatibility warning(s)
+---------------------------------
+
+This release has a few changes in the user-visible output from
+Porcelain commands. These are not meant to be parsed by scripts, but
+users still may want to be aware of the changes:
+
+ * The output from "git log --decorate" (and, more generally, the "%d"
+   format specifier used in the "--format=<string>" parameter to the
+   "git log" family of commands) has changed. It used to list "HEAD"
+   just like other branches; e.g.,
+
+     $ git log --decorate -1 master
+     commit bdb0f6788fa5e3cacc4315e9ff318a27b2676ff4 (HEAD, master)
+     ...
+
+   This release changes the output slightly when HEAD refers to a
+   branch whose name is also shown in the output. The above is now
+   shown as:
+
+     $ git log --decorate -1 master
+     commit bdb0f6788fa5e3cacc4315e9ff318a27b2676ff4 (HEAD -> master)
+     ...
+
+ * The phrasing "git branch" uses to describe a detached HEAD has been
+   updated to agree with the phrasing used by "git status":
+
+    - When HEAD is at the same commit as when it was originally
+      detached, they now both show "detached at <commit object name>".
+
+    - When HEAD has moved since it was originally detached, they now
+      both show "detached from <commit object name>".
+
+   Previously, "git branch" always used "from".
+
+
+Updates since v2.3
+------------------
+
+Ports
+
+ * Our default I/O size (8 MiB) for large files was too large for some
+   platforms with smaller SSIZE_MAX, leading to read(2)/write(2)
+   failures.
+
+ * We did not check the curl library version before using the
+   CURLOPT_PROXYAUTH feature, which did not exist in older versions of
+   the library.
+
+ * We now detect number of CPUs on older BSD-derived systems.
+
+ * Portability fixes and workarounds for shell scripts have been added
+   to help BSD-derived systems.
+
+
+UI, Workflows & Features
+
+ * The command usage info strings given by "git cmd -h" and in
+   documentation have been tweaked for consistency.
+
+ * The "sync" subcommand of "git p4" now allows users to exclude
+   subdirectories like its "clone" subcommand does.
+
+ * "git log --invert-grep --grep=WIP" will show only commits that do
+   not have the string "WIP" in their messages.
+
+ * "git push" has been taught an "--atomic" option that makes a push
+   that updates more than one ref an "all-or-none" affair.
+
+ * Extending the "push to deploy" feature that was added in 2.3, the
+   behaviour of "git push" when updating the branch that is checked
+   out can now be tweaked by a "push-to-checkout" hook.
+
+ * HTTP-based transports now send Accept-Language when making
+   requests. The languages to accept are inferred from environment
+   variables on the client side (LANGUAGE, etc).
+
+ * "git send-email" used to accept a mistaken "y" (or "yes") as an
+   answer to "What encoding do you want to use [UTF-8]?" without
+   questioning. Now it asks for confirmation when the answer looks too
+   short to be a valid encoding name.
+
+ * When "git apply --whitespace=fix" fixed whitespace errors in the
+   common context lines, the command reports that it did so.
+
+ * "git status" now allows the "-v" option to be given twice, in which
+   case it also shows the differences in the working tree that are not
+   staged to be committed.
+
+ * "git cherry-pick" used to clean up the log message even when it is
+   merely replaying an existing commit. It now replays the message
+   verbatim unless you are editing the message of the resulting
+   commit.
+
+ * "git archive" can now be told to set the 'text' attribute in the
+   resulting zip archive.
+
+ * Output from "git log --decorate" now distinguishes between a
+   detached HEAD vs. a HEAD that points at a branch.
+
+   This is a potentially backward-incompatible change; see above for
+   more information.
+
+ * When HEAD was detached when at commit xyz and hasn't been moved
+   since it was detached, "git status" would report "detached at xyz"
+   whereas "git branch" would report "detached from xyz". Now the
+   output of "git branch" agrees with that of "git status".
+
+   This is a potentially backward-incompatible change; see above for
+   more information.
+
+ * "git -C '' subcmd" now works in the current directory (analogously
+   to "cd ''") rather than dying with an error message.
+   (merge 6a536e2 kn/git-cd-to-empty later to maint).
+
+ * The versionsort.prereleaseSuffix configuration variable can be used
+   to specify that, for example, v1.0-pre1 comes before v1.0.
+
+ * A new "push.followTags" configuration turns the "--follow-tags"
+   option on by default for the "git push" command.
+
+ * "git log --graph --no-walk A B..." is a nonsensical combination of
+   options: "--no-walk" requests discrete points in the history, while
+   "--graph" asks to draw connections between these discrete points.
+   Forbid the use of these options together.
+
+ * "git rev-list --bisect --first-parent" does not work (yet) and can
+   even cause SEGV; forbid it. "git log --bisect --first-parent" would
+   not be useful until "git bisect --first-parent" materializes, so
+   also forbid it for now.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * Slightly change the implementation of the N_() macro to help us
+   detect mistakes.
+
+ * Restructure the implementation of "reflog expire" to fit better
+   with the recently updated reference API.
+
+ * The transport-helper did not pass transport options such as
+   verbosity, progress, cloning, etc. to import and export based
+   helpers, like it did for fetch and push based helpers, robbing them
+   of the chance to honor the wish of the end-users better.
+
+ * The tests that wanted to see that a file becomes unreadable after
+   running "chmod a-r file", and the tests that wanted to make sure
+   that they are not run as root, used "can we write into the /
+   directory?" as a cheap substitute. But on some platforms that is
+   not a good heuristic. The tests and their prerequisites have been
+   updated to check what they really require.
+   (merge f400e51 jk/sanity later to maint).
+
+ * Various issues around "reflog expire", e.g. using --updateref when
+   expiring a reflog for a symbolic reference, have been corrected
+   and/or made saner.
+
+ * The documentation for the strbuf API had been split between the API
+   documentation and the header file. Consolidate the documentation in
+   strbuf.h.
+
+ * The error handling functions and conventions are now documented in
+   the API manual (in api-error-handling.txt).
+
+ * Optimize gitattribute look-up, mostly useful in "git grep" on a
+   project that does not use many attributes, by avoiding it when we
+   (should) know that the attributes are not defined in the first
+   place.
+
+ * Typofix in comments.
+   (merge ef2956a ak/git-pm-typofix later to maint).
+
+ * Code clean-up.
+   (merge 0b868f0 sb/hex-object-name-is-at-most-41-bytes-long later to maint).
+   (merge 5d30851 dp/remove-duplicated-header-inclusion later to maint).
+
+ * Simplify the ref transaction API for verifying that "the ref should
+   be pointing at this object".
+
+ * Simplify the code in "git daemon" that parses out and holds
+   hostnames used in request interpolation.
+
+ * Restructure the "git push" codepath to make it easier to add new
+   configuration bits.
+
+ * The run-command interface made it easy to make a pipe for us to
+   read from a process, wait for the process to finish, and then
+   attempt to read its output. But this pattern can lead to deadlock.
+   So introduce a helper to do this correctly (i.e., first read, and
+   then wait the process to finish) and also add code to prevent such
+   abuse in the run-command helper.
+
+ * People often forget to chain the commands in their test together
+   with &&, letting a failure from an earlier command in the test go
+   unnoticed. The new GIT_TEST_CHAIN_LINT mechanism allows you to
+   catch such a mistake more easily.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.3
+----------------
+
+Unless otherwise noted, all the fixes since v2.3 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git blame HEAD -- missing" failed to correctly say "HEAD" when it
+   tried to say "No such path 'missing' in HEAD".
+   (merge a46442f jk/blame-commit-label later to maint).
+
+ * "git rerere" (invoked internally from many mergy operations) did
+   not correctly signal errors when it attempted to update the working
+   tree files but failed for whatever reason.
+   (merge 89ea903 jn/rerere-fail-on-auto-update-failure later to maint).
+
+ * Setting diff.submodule to 'log' made "git format-patch" produce
+   broken patches.
+   (merge 339de50 dk/format-patch-ignore-diff-submodule later to maint).
+
+ * After attempting and failing a password-less authentication (e.g.,
+   Kerberos), libcURL refuses to fall back to password-based Basic
+   authentication without a bit of help/encouragement.
+   (merge 4dbe664 bc/http-fallback-to-password-after-krb-fails later to maint).
+
+ * The "git push" documentation for the "--repo=<there>" option was
+   easily misunderstood.
+   (merge 57b92a7 mg/push-repo-option-doc later to maint).
+
+ * Code to read a branch name from various files in the .git/
+   directory would have overrun array limits if asked to read an empty
+   file.
+   (merge 66ec904 jk/status-read-branch-name-fix later to maint).
+
+ * Remove a superfluous conditional that is always true.
+   (merge 94ee8e2 jk/remote-curl-an-array-in-struct-cannot-be-null later to maint).
+
+ * The "git diff --raw" documentation incorrectly implied that C(opy)
+   and R(ename) are the only statuses that can be followed by a score
+   number.
+   (merge ac1c2d9 jc/diff-format-doc later to maint).
+
+ * A broken pack .idx file in the receiving repository prevented the
+   dumb http transport from fetching a good copy of it from the other
+   side.
+   (merge 8b9c2dd jk/dumb-http-idx-fetch-fix later to maint).
+
+ * The error message from "git commit", when a non-existing author
+   name was given as value to the "--author=" parameter, has been
+   reworded to avoid misunderstanding.
+   (merge 1044b1f mg/commit-author-no-match-malformed-message later to maint).
+
+ * "git log --help" used to show rev-list options that are irrelevant
+   to the "log" command.
+   (merge 3cab02d jc/doc-log-rev-list-options later to maint).
+
+ * "git apply --whitespace=fix" used to under-allocate memory when the
+   fix resulted in a longer text than the original patch.
+   (merge 407a792 jc/apply-ws-fix-expands later to maint).
+
+ * The interactive "show a list and let the user choose from it"
+   interface used by "git add -i" unnecessarily prompted the user even
+   when the candidate list was empty, against which the only "choice"
+   the user could have made was to choose nothing.
+   (merge a9c4641 ak/add-i-empty-candidates later to maint).
+
+ * The todo list created by "git rebase -i" did not fully honor
+   core.abbrev settings.
+   (merge edb72d5 ks/rebase-i-abbrev later to maint).
+
+ * "git fetch" over a remote-helper that cannot respond to the "list"
+   command could not fetch from a symbolic reference (e.g., HEAD).
+   (merge 33cae54 mh/deref-symref-over-helper-transport later to maint).
+
+ * "git push --signed" gave an incorrectly worded error message when
+   the other side did not support the capability.
+
+ * The "git push --signed" protocol extension did not limit what the
+   "nonce" (a server-chosen string) could contain nor how long it
+   could be, which was unnecessarily lax. Limit both the length and
+   the alphabet to a reasonably small space that can still have enough
+   entropy.
+   (merge afcb6ee jc/push-cert later to maint).
+
+ * The completion script (in contrib/) clobbered the shell variable $x
+   in the global shell namespace.
+   (merge 852ff1c ma/bash-completion-leaking-x later to maint).
+
+ * We incorrectly formatted a "uintmax_t" integer that doesn't fit in
+   "int".
+   (merge d306f3d jk/decimal-width-for-uintmax later to maint).
+
+ * The configuration parser used to be confused when reading
+   configuration from a blob object that ends with a lone CR.
+   (merge 1d0655c jk/config-no-ungetc-eof later to maint).
+
+ * The pack bitmap support did not build with older versions of GCC.
+   (merge bd4e882 jk/pack-bitmap later to maint).
+
+ * The documentation wasn't clear that "remote.<nick>.pushURL" and
+   "remote.<nick>.URL" are there to name the same repository accessed
+   via different transports, not two separate repositories.
+   (merge 697f652 jc/remote-set-url-doc later to maint).
+
+ * Older GnuPG implementations may not correctly import the keyring
+   material we prepare for the tests to use.
+   (merge 1f985d6 ch/new-gpg-drops-rfc-1991 later to maint).
+
+ * The credential helper for Windows (in contrib/) used to mishandle
+   user names that contain an at-sign.
+   (merge 13d261e av/wincred-with-at-in-username-fix later to maint).
+
+ * "diff-highlight" (in contrib/) used to show byte-by-byte
+   differences, which could cause multi-byte characters to be chopped
+   in the middle. It learned to pay attention to character boundaries
+   (assuming UTF-8).
+   (merge 8d00662 jk/colors later to maint).
+
+ * Document longstanding configuration variable naming rules in
+   CodingGuidelines.
+   (merge 35840a3 jc/conf-var-doc later to maint).
+
+ * An earlier workaround to squelch unhelpful deprecation warnings
+   from the compiler on OS X unnecessarily set a minimum required
+   version of the OS, which the user might want to raise (or lower)
+   for other reasons.
+   (merge 88c03eb es/squelch-openssl-warnings-on-macosx later to maint).
+
+ * Certain older vintages of cURL give irregular output from
+   "curl-config --vernum", which confused our build system.
+   (merge 3af6792 tc/curl-vernum-output-broken-in-7.11 later to maint).
+
+ * In v2.2.0, we broke "git prune" that runs in a repository that
+   borrows from an alternate object store.
+   (merge b0a4264 jk/prune-mtime later to maint).
+
+ * "git submodule add" failed to squash "path/to/././submodule" to
+   "path/to/submodule".
+   (merge 8196e72 ps/submodule-sanitize-path-upon-add later to maint).
+
+ * "git merge-file" did not work correctly when invoked in a
+   subdirectory.
+   (merge 204a8ff ab/merge-file-prefix later to maint).
+
+ * "git blame" could die trying to free an uninitialized piece of
+   memory.
+   (merge e600592 es/blame-commit-info-fix later to maint).
+
+ * "git fast-import" used to crash when it could not close and
+   finalize the resulting packfile cleanly.
+   (merge 5e915f3 jk/fast-import-die-nicely-fix later to maint).
+
+ * "update-index --refresh" used to leak memory when an entry could
+   not be refreshed for whatever reason.
+   (merge bc1c2ca sb/plug-leak-in-make-cache-entry later to maint).
+
+ * The "interpolated-path" option of "git daemon" inserted any string
+   the client declared on the "host=" capability request without
+   checking. Sanitize and limit %H and %CH to a saner and a valid DNS
+   name.
+   (merge b485373 jk/daemon-interpolate later to maint).
+
+ * "git daemon" unnecessarily looked up the hostname even when "%CH"
+   and "%IP" interpolations were not requested.
+   (merge dc8edc8 rs/daemon-interpolate later to maint).
+
+ * We relied on "--no-" prefix handling in Perl's Getopt::Long
+   package, even though that support didn't exist in Perl 5.8 (which
+   we still support). Manually add support to help people with older
+   Getopt::Long packages.
+   (merge f471494 km/send-email-getopt-long-workarounds later to maint).
+
+ * "git apply" was not very careful about reading from, removing,
+   updating and creating paths outside the working tree (under
+   --index/--cached) or the current directory (when used as a
+   replacement for GNU patch).
+   (merge e0d201b jc/apply-beyond-symlink later to maint).
+
+ * Correct a breakage in git-svn, introduced around the v2.2 era, that
+   can cause FileHandles to be closed prematurely.
+   (merge e426311 ew/svn-maint-fixes later to maint).
+
+ * We did not parse usernames followed by literal IPv6 addresses
+   correctly in SSH transport URLs; e.g.,
+   ssh://user@[2001:db8::1]:22/repo.git.
+   (merge 6b6c5f7 tb/connect-ipv6-parse-fix later to maint).
+
+ * The configuration variable 'mailinfo.scissors' was hard to
+   discover in the documentation.
+   (merge afb5de7 mm/am-c-doc later to maint).
+
+ * The interaction between "git submodule update" and the
+   submodule.*.update configuration was not clearly documented.
+   (merge 5c31acf ms/submodule-update-config-doc later to maint).
+
+ * "git diff --shortstat" used together with "--dirstat=changes" or
+   "--dirstat=files" incorrectly output dirstat information twice.
+   (merge ab27389 mk/diff-shortstat-dirstat-fix later to maint).
+
+ * The manpage for "git remote add" mentioned "--tags" and "--no-tags"
+   but did not explain what happens if neither option is provided.
+   (merge aaba0ab mg/doc-remote-tags-or-not later to maint).
+
+ * The description of "--exclude-standard option" in the output of
+   "git grep -h" was phrased poorly.
+   (merge 77fdb8a nd/grep-exclude-standard-help-fix later to maint).
+
+ * "git rebase -i" recently started to include the number of commits
+   in the todo list, but that output included extraneous whitespace on
+   a platform that prepends leading whitespaces to its "wc -l" output.
+   (merge 2185d3b es/rebase-i-count-todo later to maint).
+
+ * The borrowed code in the kwset API did not follow our usual
+   convention to use "unsigned char" to store values that range from
+   0-255.
+   (merge 189c860 bw/kwset-use-unsigned later to maint).
+
+ * A corrupt input to "git diff -M" used to cause it to segfault.
+   (merge 4d6be03 jk/diffcore-rename-duplicate later to maint).
+
+ * Certain builds of GPG triggered false breakages in a test.
+   (merge 3f88c1b mg/verify-commit later to maint).
+
+ * "git imap-send" learned to optionally talk with an IMAP server via
+   libcURL. Because there is no other option when Git is built with
+   the NO_OPENSSL option, use libcURL by default in that case.
+   (merge dcd01ea km/imap-send-libcurl-options later to maint).
+
+ * "git log --decorate" did not reset colors correctly around the
+   branch names.
+   (merge 5ee8758 jc/decorate-leaky-separator-color later to maint).
+
+ * The code that reads from the ctags file in the completion script
+   (in contrib/) did not spell ${param/pattern/string} substitution
+   correctly, which happened to work with bash but not with zsh.
+   (merge db8d750 js/completion-ctags-pattern-substitution-fix later to maint).
+
+ * The transfer.hiderefs support did not quite work for smart-http
+   transport.
+   (merge 8ddf3ca jk/smart-http-hide-refs later to maint).
+
+ * In the "git tag -h" output, move the documentation for the
+   "--column" and "--sort" options to the "Tag listing options"
+   section.
+   (merge dd059c6 jk/tag-h-column-is-a-listing-option later to maint).
+
+ * "git prune" used to largely ignore broken refs when deciding which
+   objects are still being used, which could cause reference
+   corruption to lead to object loss.
+   (merge ea56c4e jk/prune-with-corrupt-refs later to maint).
+
+ * The split-index mode introduced in v2.3.0-rc0~41 was broken in the
+   codepath to protect us against a broken reimplementation of Git
+   that writes an invalid index with duplicated index entries, etc.
+   (merge 03f15a7 tg/fix-check-order-with-split-index later to maint).
+
+ * "git fetch", when fetching a commit using the
+   allow-tip-sha1-in-want extension, could have failed to fetch all of
+   the requested refs.
+   (merge 32d0462 jk/fetch-pack later to maint).
+
+ * An failure early in the "git clone" that started creating the
+   working tree and repository could have resulted in the failure to
+   clean up some directories and files.
+   (merge 16eff6c jk/cleanup-failed-clone later to maint).
+
+ * Recommend format-patch and send-email for those who want to submit
+   patches to this project.
+   (merge b25c469 jc/submitting-patches-mention-send-email later to maint).
+
+ * Do not spawn the pager when "git grep" is run with "--quiet".
+   (merge c2048f0 ws/grep-quiet-no-pager later to maint).
+
+ * The prompt script (in contrib/) did not show the untracked sign
+   when working in a subdirectory without any untracked files.
+   (merge 9bdc517 ct/prompt-untracked-fix later to maint).
+
+ * An earlier update to the URL parser broke an address that contains
+   a colon but an empty string for the port number, like
+   ssh://example.com:/path/to/repo.
+   (merge 6b6c5f7 tb/connect-ipv6-parse-fix later to maint).
+
+ * Code cleanups and documentation updates.
+   (merge 2ce63e9 rs/simple-cleanups later to maint).
+   (merge 33baa69 rj/no-xopen-source-for-cygwin later to maint).
+   (merge 817d03e jc/diff-test-updates later to maint).

+Git v2.4.1 Release Notes
+========================
+
+Fixes since v2.4
+----------------
+
+ * The usual "git diff" when seeing a file turning into a directory
+   showed a patchset to remove the file and create all files in the
+   directory, but "git diff --no-index" simply refused to work.  Also,
+   when asked to compare a file and a directory, imitate POSIX "diff"
+   and compare the file with the file with the same name in the
+   directory, instead of refusing to run.
+
+ * The default $HOME/.gitconfig file created upon "git config --global"
+   that edits it had incorrectly spelled user.name and user.email
+   entries in it.
+
+ * "git commit --date=now" or anything that relies on approxidate lost
+   the daylight-saving-time offset.
+
+ * "git cat-file bl $blob" failed to barf even though there is no
+   object type that is "bl".
+
+ * Teach the codepaths that read .gitignore and .gitattributes files
+   that these files encoded in UTF-8 may have UTF-8 BOM marker at the
+   beginning; this makes it in line with what we do for configuration
+   files already.
+
+ * Access to objects in repositories that borrow from another one on a
+   slow NFS server unnecessarily got more expensive due to recent code
+   becoming more cautious in a naive way not to lose objects to pruning.
+
+ * We avoid setting core.worktree when the repository location is the
+   ".git" directory directly at the top level of the working tree, but
+   the code misdetected the case in which the working tree is at the
+   root level of the filesystem (which arguably is a silly thing to
+   do, but still valid).
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.4.10 Release Notes
+=========================
+
+Fixes since v2.4.9
+------------------
+
+ * xdiff code we use to generate diffs is not prepared to handle
+   extremely large files.  It uses "int" in many places, which can
+   overflow if we have a very large number of lines or even bytes in
+   our input files, for example.  Cap the input size to soemwhere
+   around 1GB for now.
+
+ * Some protocols (like git-remote-ext) can execute arbitrary code
+   found in the URL.  The URLs that submodules use may come from
+   arbitrary sources (e.g., .gitmodules files in a remote
+   repository), and can hurt those who blindly enable recursive
+   fetch.  Restrict the allowed protocols to well known and safe
+   ones.

+Git v2.4.2 Release Notes
+========================
+
+Fixes since v2.4.1
+------------------
+
+ * "git rev-list --objects $old --not --all" to see if everything that
+   is reachable from $old is already connected to the existing refs
+   was very inefficient.
+
+ * "hash-object --literally" introduced in v2.2 was not prepared to
+   take a really long object type name.
+
+ * "git rebase --quiet" was not quite quiet when there is nothing to
+   do.
+
+ * The completion for "log --decorate=" parameter value was incorrect.
+
+ * "filter-branch" corrupted commit log message that ends with an
+   incomplete line on platforms with some "sed" implementations that
+   munge such a line.  Work it around by avoiding to use "sed".
+
+ * "git daemon" fails to build from the source under NO_IPV6
+   configuration (regression in 2.4).
+
+ * "git stash pop/apply" forgot to make sure that not just the working
+   tree is clean but also the index is clean. The latter is important
+   as a stash application can conflict and the index will be used for
+   conflict resolution.
+
+ * We have prepended $GIT_EXEC_PATH and the path "git" is installed in
+   (typically "/usr/bin") to $PATH when invoking subprograms and hooks
+   for almost eternity, but the original use case the latter tried to
+   support was semi-bogus (i.e. install git to /opt/foo/git and run it
+   without having /opt/foo on $PATH), and more importantly it has
+   become less and less relevant as Git grew more mainstream (i.e. the
+   users would _want_ to have it on their $PATH).  Stop prepending the
+   path in which "git" is installed to users' $PATH, as that would
+   interfere the command search order people depend on (e.g. they may
+   not like versions of programs that are unrelated to Git in /usr/bin
+   and want to override them by having different ones in /usr/local/bin
+   and have the latter directory earlier in their $PATH).
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.4.3 Release Notes
+========================
+
+Fixes since v2.4.3
+------------------
+
+ * Error messages from "git branch" called remote-tracking branches as
+   "remote branches".
+
+ * "git rerere forget" in a repository without rerere enabled gave a
+   cryptic error message; it should be a silent no-op instead.
+
+ * "git pull --log" and "git pull --no-log" worked as expected, but
+   "git pull --log=20" did not.
+
+ * The pull.ff configuration was supposed to override the merge.ff
+   configuration, but it didn't.
+
+ * The code to read pack-bitmap wanted to allocate a few hundred
+   pointers to a structure, but by mistake allocated and leaked memory
+   enough to hold that many actual structures.  Correct the allocation
+   size and also have it on stack, as it is small enough.
+
+ * Various documentation mark-up fixes to make the output more
+   consistent in general and also make AsciiDoctor (an alternative
+   formatter) happier.
+
+ * "git bundle verify" did not diagnose extra parameters on the
+   command line.
+
+ * Multi-ref transaction support we merged a few releases ago
+   unnecessarily kept many file descriptors open, risking to fail with
+   resource exhaustion.
+
+ * The ref API did not handle cases where 'refs/heads/xyzzy/frotz' is
+   removed at the same time as 'refs/heads/xyzzy' is added (or vice
+   versa) very well.
+
+ * The "log --decorate" enhancement in Git 2.4 that shows the commit
+   at the tip of the current branch e.g. "HEAD -> master", did not
+   work with --decorate=full.
+
+ * There was a commented-out (instead of being marked to expect
+   failure) test that documented a breakage that was fixed since the
+   test was written; turn it into a proper test.
+
+ * core.excludesfile (defaulting to $XDG_HOME/git/ignore) is supposed
+   to be overridden by repository-specific .git/info/exclude file, but
+   the order was swapped from the beginning. This belatedly fixes it.
+
+ * The connection initiation code for "ssh" transport tried to absorb
+   differences between the stock "ssh" and Putty-supplied "plink" and
+   its derivatives, but the logic to tell that we are using "plink"
+   variants were too loose and falsely triggered when "plink" appeared
+   anywhere in the path (e.g. "/home/me/bin/uplink/ssh").
+
+ * "git rebase -i" moved the "current" command from "todo" to "done" a
+   bit too prematurely, losing a step when a "pick" did not even start.
+
+ * "git add -e" did not allow the user to abort the operation by
+   killing the editor.
+
+ * Git 2.4 broke setting verbosity and progress levels on "git clone"
+   with native transports.
+
+ * Some time ago, "git blame" (incorrectly) lost the convert_to_git()
+   call when synthesizing a fake "tip" commit that represents the
+   state in the working tree, which broke folks who record the history
+   with LF line ending to make their project portabile across
+   platforms while terminating lines in their working tree files with
+   CRLF for their platform.
+
+ * Code clean-up for xdg configuration path support.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.4.4 Release Notes
+========================
+
+Fixes since v2.4.3
+------------------
+
+ * l10n updates for German.
+
+ * An earlier leakfix to bitmap testing code was incomplete.
+
+ * "git clean pathspec..." tried to lstat(2) and complain even for
+   paths outside the given pathspec.
+
+ * Communication between the HTTP server and http_backend process can
+   lead to a dead-lock when relaying a large ref negotiation request.
+   Diagnose the situation better, and mitigate it by reading such a
+   request first into core (to a reasonable limit).
+
+ * The clean/smudge interface did not work well when filtering an
+   empty contents (failed and then passed the empty input through).
+   It can be argued that a filter that produces anything but empty for
+   an empty input is nonsense, but if the user wants to do strange
+   things, then why not?
+
+ * Make "git stash something --help" error out, so that users can
+   safely say "git stash drop --help".
+
+ * Clarify that "log --raw" and "log --format=raw" are unrelated
+   concepts.
+
+ * Catch a programmer mistake to feed a pointer not an array to
+   ARRAY_SIZE() macro, by using a couple of GCC extensions.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.4.5 Release Notes
+========================

+------------------
+
+ * The setup code used to die when core.bare and core.worktree are set

+
+ * There was a dead code that used to handle "git pull --tags" and
+   show special-cased error message, which was made irrelevant when

+ * "color.diff.plain" was a misnomer; give it 'color.diff.context' as

+
+ * The configuration reader/writer uses mmap(2) interface to access
+   the files; when we find a directory, it barfed with "Out of memory?".
+
+ * Recent "git prune" traverses young unreachable objects to safekeep
+   old objects in the reachability chain from them, which sometimes

+Git v2.4.7 Release Notes
+========================
+
+Fixes since v2.4.6
+------------------
+
+ * A minor regression to "git fsck" in v2.2 era was fixed; it
+   complained about a body-less tag object when it lacked a
+   separator empty line after its header to separate it with a
+   non-existent body.
+
+ * We used to ask libCURL to use the most secure authentication method
+   available when talking to an HTTP proxy only when we were told to
+   talk to one via configuration variables.  We now ask libCURL to
+   always use the most secure authentication method, because the user
+   can tell libCURL to use an HTTP proxy via an environment variable
+   without using configuration variables.
+
+ * When you say "!<ENTER>" while running say "git log", you'd confuse
+   yourself in the resulting shell, that may look as if you took
+   control back to the original shell you spawned "git log" from but
+   that isn't what is happening.  To that new shell, we leaked
+   GIT_PAGER_IN_USE environment variable that was meant as a local
+   communication between the original "Git" and subprocesses that was
+   spawned by it after we launched the pager, which caused many
+   "interesting" things to happen, e.g. "git diff | cat" still paints
+   its output in color by default.
+
+   Stop leaking that environment variable to the pager's half of the
+   fork; we only need it on "Git" side when we spawn the pager.
+
+ * Avoid possible ssize_t to int truncation.
+
+ * "git config" failed to update the configuration file when the
+   underlying filesystem is incapable of renaming a file that is still
+   open.
+
+ * A minor bugfix when pack bitmap is used with "rev-list --count".
+
+ * An ancient test framework enhancement to allow color was not
+   entirely correct; this makes it work even when tput needs to read
+   from the ~/.terminfo under the user's real HOME directory.
+
+ * Fix a small bug in our use of umask() return value.
+
+ * "git rebase" did not exit with failure when format-patch it invoked
+   failed for whatever reason.
+
+ * Disable "have we lost a race with competing repack?" check while
+   receiving a huge object transfer that runs index-pack.
+
+Also contains typofixes, documentation updates and trivial code

+Git 2.5 Release Notes
+=====================
+
+Updates since v2.4
+------------------
+
+UI, Workflows & Features
+
+ * The bash completion script (in contrib/) learned a few options that
+   "git revert" takes.
+
+ * Whitespace breakages in deleted and context lines can also be
+   painted in the output of "git diff" and friends with the new
+   --ws-error-highlight option.
+
+ * List of commands shown by "git help" are grouped along the workflow
+   elements to help early learners.
+
+ * "git p4" now detects the filetype (e.g. binary) correctly even when
+   the files are opened exclusively.
+
+ * git p4 attempts to better handle branches in Perforce.
+
+ * "git p4" learned "--changes-block-size <n>" to read the changes in
+   chunks from Perforce, instead of making one call to "p4 changes"
+   that may trigger "too many rows scanned" error from Perforce.
+
+ * More workaround for Perforce's row number limit in "git p4".
+
+ * Unlike "$EDITOR" and "$GIT_EDITOR" that can hold the path to the
+   command and initial options (e.g. "/path/to/emacs -nw"), 'git p4'
+   did not let the shell interpolate the contents of the environment
+   variable that name the editor "$P4EDITOR" (and "$EDITOR", too).
+   This release makes it in line with the rest of Git, as well as with
+   Perforce.
+
+ * A new short-hand <branch>@{push} denotes the remote-tracking branch
+   that tracks the branch at the remote the <branch> would be pushed
+   to.
+
+ * "git show-branch --topics HEAD" (with no other arguments) did not
+   do anything interesting.  Instead, contrast the given revision
+   against all the local branches by default.
+
+ * A replacement for contrib/workdir/git-new-workdir that does not
+   rely on symbolic links and make sharing of objects and refs safer
+   by making the borrowee and borrowers aware of each other.
+
+   Consider this as still an experimental feature; its UI is still
+   likely to change.
+
+ * Tweak the sample "store" backend of the credential helper to honor
+   XDG configuration file locations when specified.
+
+ * A heuristic we use to catch mistyped paths on the command line
+   "git <cmd> <revs> <pathspec>" is to make sure that all the non-rev
+   parameters in the later part of the command line are names of the
+   files in the working tree, but that means "git grep $str -- \*.c"
+   must always be disambiguated with "--", because nobody sane will
+   create a file whose name literally is asterisk-dot-see.  Loosen the
+   heuristic to declare that with a wildcard string the user likely
+   meant to give us a pathspec.
+
+ * "git merge FETCH_HEAD" learned that the previous "git fetch" could
+   be to create an Octopus merge, i.e. recording multiple branches
+   that are not marked as "not-for-merge"; this allows us to lose an
+   old style invocation "git merge <msg> HEAD $commits..." in the
+   implementation of "git pull" script; the old style syntax can now
+   be deprecated (but not removed yet).
+
+ * Filter scripts were run with SIGPIPE disabled on the Git side,
+   expecting that they may not read what Git feeds them to filter.
+   We however treated a filter that does not read its input fully
+   before exiting as an error.  We no longer do and ignore EPIPE
+   when writing to feed the filter scripts.
+
+   This changes semantics, but arguably in a good way.  If a filter
+   can produce its output without fully consuming its input using
+   whatever magic, we now let it do so, instead of diagnosing it
+   as a programming error.
+
+ * Instead of dying immediately upon failing to obtain a lock, the
+   locking (of refs etc) retries after a short while with backoff.
+
+ * Introduce http.<url>.SSLCipherList configuration variable to tweak
+   the list of cipher suite to be used with libcURL when talking with
+   https:// sites.
+
+ * "git subtree" script (in contrib/) used "echo -n" to produce
+   progress messages in a non-portable way.
+
+ * "git subtree" script (in contrib/) does not have --squash option
+   when pushing, but the documentation and help text pretended as if
+   it did.
+
+ * The Git subcommand completion (in contrib/) no longer lists credential
+   helpers among candidates; they are not something the end user would
+   invoke interactively.
+
+ * The index file can be taught with "update-index --untracked-cache"
+   to optionally remember already seen untracked files, in order to
+   speed up "git status" in a working tree with tons of cruft.
+
+ * "git mergetool" learned to drive WinMerge as a backend.
+
+ * "git upload-pack" that serves "git fetch" can be told to serve
+   commits that are not at the tip of any ref, as long as they are
+   reachable from a ref, with uploadpack.allowReachableSHA1InWant
+   configuration variable.
+
+ * "git cat-file --batch(-check)" learned the "--follow-symlinks"
+   option that follows an in-tree symbolic link when asked about an
+   object via extended SHA-1 syntax, e.g. HEAD:RelNotes that points at
+   Documentation/RelNotes/2.5.0.txt.  With the new option, the command
+   behaves as if HEAD:Documentation/RelNotes/2.5.0.txt was given as
+   input instead.
+
+   Consider this as still an experimental and incomplete feature:
+
+    - We may want to do the same for in-index objects, e.g.
+      asking for :RelNotes with this option should give
+      :Documentation/RelNotes/2.5.0.txt, too
+
+    - "git cat-file --follow-symlinks blob HEAD:RelNotes"
+      may also be something we want to allow in the future.
+
+ * "git send-email" learned the alias file format used by the sendmail
+   program (in a simplified form; we obviously do not feed pipes).
+
+ * Traditionally, external low-level 3-way merge drivers are expected
+   to produce their results based solely on the contents of the three
+   variants given in temporary files named by %O, %A and %B on their
+   command line.  Additionally allow them to look at the final path
+   (given by %P).
+
+ * "git blame" learned blame.showEmail configuration variable.
+
+ * "git apply" cannot diagnose a patch corruption when the breakage is
+   to mark the length of the hunk shorter than it really is on the
+   hunk header line "@@ -l,k +m,n @@"; one special case it could is
+   when the hunk becomes no-op (e.g. k == n == 2 for two-line context
+   patch output), and it learned to do so in this special case.
+
+ * Add the "--allow-unknown-type" option to "cat-file" to allow
+   inspecting loose objects of an experimental or a broken type.
+
+ * Many long-running operations show progress eye-candy, even when
+   they are later backgrounded.  Hide the eye-candy when the process
+   is sent to the background instead.
+   (merge a4fb76c lm/squelch-bg-progress later to maint).
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * "unsigned char [20]" used throughout the code to represent object
+   names are being converted into a semi-opaque "struct object_id".
+   This effort is expected to interfere with other topics in flight,
+   but hopefully will give us one extra level of abstraction in the
+   end, when completed.
+
+ * for_each_ref() callback functions were taught to name the objects
+   not with "unsigned char sha1[20]" but with "struct object_id".
+
+ * Catch a programmer mistake to feed a pointer not an array to
+   ARRAY_SIZE() macro, by using a couple of GCC extensions.
+
+ * Some error messages in "git config" were emitted without calling
+   the usual error() facility.
+
+ * When "add--interactive" splits a hunk into two overlapping hunks
+   and then let the user choose only one, it sometimes feeds an
+   incorrect patch text to "git apply".  Add tests to demonstrate
+   this.
+
+   I have a slight suspicion that this may be $gmane/87202 coming back
+   and biting us (I seem to have said "let's run with this and see
+   what happens" back then).
+
+ * More line-ending tests.
+
+ * An earlier rewrite to use strbuf_getwholeline() instead of fgets(3)
+   to read packed-refs file revealed that the former is unacceptably
+   inefficient.  It has been optimized by using getdelim(3) when
+   available.
+
+ * The refs API uses ref_lock struct which had its own "int fd", even
+   though the same file descriptor was in the lock struct it contains.
+   Clean-up the code to lose this redundant field.
+
+ * There was a dead code that used to handle "git pull --tags" and
+   show special-cased error message, which was made irrelevant when
+   the semantics of the option changed back in Git 1.9 days.
+   (merge 19d122b pt/pull-tags-error-diag later to maint).
+
+ * Help us to find broken test script that splits the body part of the
+   test by mistaken use of wrong kind of quotes.
+   (merge d93d5d5 jc/test-prereq-validate later to maint).
+
+ * Developer support to automatically detect broken &&-chain in the
+   test scripts is now turned on by default.
+   (merge 92b269f jk/test-chain-lint later to maint).
+
+ * Error reporting mechanism used in "refs" API has been made more
+   consistent.
+
+ * "git pull" has more test coverage now.
+
+ * "git pull" has become more aware of the options meant for
+   underlying "git fetch" and then learned to use parse-options
+   parser.
+
+ * Clarify in the Makefile a guideline to decide use of USE_NSEC.
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.4
+----------------
+
+Unless otherwise noted, all the fixes since v2.4 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * Git 2.4 broke setting verbosity and progress levels on "git clone"
+   with native transports.
+   (merge 822f0c4 mh/clone-verbosity-fix later to maint).
+
+ * "git add -e" did not allow the user to abort the operation by
+   killing the editor.
+   (merge cb64800 jk/add-e-kill-editor later to maint).
+
+ * Memory usage of "git index-pack" has been trimmed by tens of
+   per-cent.
+   (merge f0e7f11 nd/slim-index-pack-memory-usage later to maint).
+
+ * "git rev-list --objects $old --not --all" to see if everything that
+   is reachable from $old is already connected to the existing refs
+   was very inefficient.
+   (merge b6e8a3b jk/still-interesting later to maint).
+
+ * "hash-object --literally" introduced in v2.2 was not prepared to
+   take a really long object type name.
+   (merge 1427a7f jc/hash-object later to maint).
+
+ * "git rebase --quiet" was not quite quiet when there is nothing to
+   do.
+   (merge 22946a9 jk/rebase-quiet-noop later to maint).
+
+ * The completion for "log --decorate=" parameter value was incorrect.
+   (merge af16bda sg/complete-decorate-full-not-long later to maint).
+
+ * "filter-branch" corrupted commit log message that ends with an
+   incomplete line on platforms with some "sed" implementations that
+   munge such a line.  Work it around by avoiding to use "sed".
+   (merge df06201 jk/filter-branch-use-of-sed-on-incomplete-line later to maint).
+
+ * "git daemon" fails to build from the source under NO_IPV6
+   configuration (regression in 2.4).
+   (merge d358f77 jc/daemon-no-ipv6-for-2.4.1 later to maint).
+
+ * Some time ago, "git blame" (incorrectly) lost the convert_to_git()
+   call when synthesizing a fake "tip" commit that represents the
+   state in the working tree, which broke folks who record the history
+   with LF line ending to make their project portable across platforms
+   while terminating lines in their working tree files with CRLF for
+   their platform.
+   (merge 4bf256d tb/blame-resurrect-convert-to-git later to maint).
+
+ * We avoid setting core.worktree when the repository location is the
+   ".git" directory directly at the top level of the working tree, but
+   the code misdetected the case in which the working tree is at the
+   root level of the filesystem (which arguably is a silly thing to
+   do, but still valid).
+   (merge 84ccad8 jk/init-core-worktree-at-root later to maint).
+
+ * "git commit --date=now" or anything that relies on approxidate lost
+   the daylight-saving-time offset.
+   (merge f6e6362 jc/epochtime-wo-tz later to maint).
+
+ * Access to objects in repositories that borrow from another one on a
+   slow NFS server unnecessarily got more expensive due to recent code
+   becoming more cautious in a naive way not to lose objects to pruning.
+   (merge ee1c6c3 jk/prune-mtime later to maint).
+
+ * The codepaths that read .gitignore and .gitattributes files have been
+   taught that these files encoded in UTF-8 may have UTF-8 BOM marker at
+   the beginning; this makes it in line with what we do for configuration
+   files already.
+   (merge 27547e5 cn/bom-in-gitignore later to maint).
+
+ * a few helper scripts in the test suite did not report errors
+   correctly.
+   (merge de248e9 ep/fix-test-lib-functions-report later to maint).
+
+ * The default $HOME/.gitconfig file created upon "git config --global"
+   that edits it had incorrectly spelled user.name and user.email
+   entries in it.
+   (merge 7e11052 oh/fix-config-default-user-name-section later to maint).
+
+ * "git cat-file bl $blob" failed to barf even though there is no
+   object type that is "bl".
+   (merge b7994af jk/type-from-string-gently later to maint).
+
+ * The usual "git diff" when seeing a file turning into a directory
+   showed a patchset to remove the file and create all files in the
+   directory, but "git diff --no-index" simply refused to work.  Also,
+   when asked to compare a file and a directory, imitate POSIX "diff"
+   and compare the file with the file with the same name in the
+   directory, instead of refusing to run.
+   (merge 0615173 jc/diff-no-index-d-f later to maint).
+
+ * "git rebase -i" moved the "current" command from "todo" to "done" a
+   bit too prematurely, losing a step when a "pick" did not even start.
+   (merge 8cbc57c ph/rebase-i-redo later to maint).
+
+ * The connection initiation code for "ssh" transport tried to absorb
+   differences between the stock "ssh" and Putty-supplied "plink" and
+   its derivatives, but the logic to tell that we are using "plink"
+   variants were too loose and falsely triggered when "plink" appeared
+   anywhere in the path (e.g. "/home/me/bin/uplink/ssh").
+   (merge baaf233 bc/connect-plink later to maint).
+
+ * We have prepended $GIT_EXEC_PATH and the path "git" is installed in
+   (typically "/usr/bin") to $PATH when invoking subprograms and hooks
+   for almost eternity, but the original use case the latter tried to
+   support was semi-bogus (i.e. install git to /opt/foo/git and run it
+   without having /opt/foo on $PATH), and more importantly it has
+   become less and less relevant as Git grew more mainstream (i.e. the
+   users would _want_ to have it on their $PATH).  Stop prepending the
+   path in which "git" is installed to users' $PATH, as that would
+   interfere the command search order people depend on (e.g. they may
+   not like versions of programs that are unrelated to Git in /usr/bin
+   and want to override them by having different ones in /usr/local/bin
+   and have the latter directory earlier in their $PATH).
+   (merge a0b4507 jk/git-no-more-argv0-path-munging later to maint).
+
+ * core.excludesfile (defaulting to $XDG_HOME/git/ignore) is supposed
+   to be overridden by repository-specific .git/info/exclude file, but
+   the order was swapped from the beginning. This belatedly fixes it.
+   (merge 099d2d8 jc/gitignore-precedence later to maint).
+
+ * There was a commented-out (instead of being marked to expect
+   failure) test that documented a breakage that was fixed since the
+   test was written; turn it into a proper test.
+   (merge 66d2e04 sb/t1020-cleanup later to maint).
+
+ * The "log --decorate" enhancement in Git 2.4 that shows the commit
+   at the tip of the current branch e.g. "HEAD -> master", did not
+   work with --decorate=full.
+   (merge 429ad20 mg/log-decorate-HEAD later to maint).
+
+ * The ref API did not handle cases where 'refs/heads/xyzzy/frotz' is
+   removed at the same time as 'refs/heads/xyzzy' is added (or vice
+   versa) very well.
+   (merge c628edf mh/ref-directory-file later to maint).
+
+ * Multi-ref transaction support we merged a few releases ago
+   unnecessarily kept many file descriptors open, risking to fail with
+   resource exhaustion.  This is for 2.4.x track.
+   (merge 185ce3a mh/write-refs-sooner-2.4 later to maint).
+
+ * "git bundle verify" did not diagnose extra parameters on the
+   command line.
+   (merge 7886cfa ps/bundle-verify-arg later to maint).
+
+ * Various documentation mark-up fixes to make the output more
+   consistent in general and also make AsciiDoctor (an alternative
+   formatter) happier.
+   (merge d0258b9 jk/asciidoc-markup-fix later to maint).
+   (merge ad3967a jk/stripspace-asciidoctor-fix later to maint).
+   (merge 975e382 ja/tutorial-asciidoctor-fix later to maint).
+
+ * The code to read pack-bitmap wanted to allocate a few hundred
+   pointers to a structure, but by mistake allocated and leaked memory
+   enough to hold that many actual structures.  Correct the allocation
+   size and also have it on stack, as it is small enough.
+   (merge 599dc76 rs/plug-leak-in-pack-bitmaps later to maint).
+
+ * The pull.ff configuration was supposed to override the merge.ff
+   configuration, but it didn't.
+   (merge db9bb28 pt/pull-ff-vs-merge-ff later to maint).
+
+ * "git pull --log" and "git pull --no-log" worked as expected, but
+   "git pull --log=20" did not.
+   (merge 5061a44 pt/pull-log-n later to maint).
+
+ * "git rerere forget" in a repository without rerere enabled gave a
+   cryptic error message; it should be a silent no-op instead.
+   (merge 0544574 jk/rerere-forget-check-enabled later to maint).
+
+ * "git rebase -i" fired post-rewrite hook when it shouldn't (namely,
+   when it was told to stop sequencing with 'exec' insn).
+   (merge 141ff8f mm/rebase-i-post-rewrite-exec later to maint).
+
+ * Clarify that "log --raw" and "log --format=raw" are unrelated
+   concepts.
+   (merge 92de921 mm/log-format-raw-doc later to maint).
+
+ * Make "git stash something --help" error out, so that users can
+   safely say "git stash drop --help".
+   (merge 5ba2831 jk/stash-options later to maint).
+
+ * The clean/smudge interface did not work well when filtering an
+   empty contents (failed and then passed the empty input through).
+   It can be argued that a filter that produces anything but empty for
+   an empty input is nonsense, but if the user wants to do strange
+   things, then why not?
+   (merge f6a1e1e jh/filter-empty-contents later to maint).
+
+ * Communication between the HTTP server and http_backend process can
+   lead to a dead-lock when relaying a large ref negotiation request.
+   Diagnose the situation better, and mitigate it by reading such a
+   request first into core (to a reasonable limit).
+   (merge 636614f jk/http-backend-deadlock later to maint).
+
+ * "git clean pathspec..." tried to lstat(2) and complain even for
+   paths outside the given pathspec.
+   (merge 838d6a9 dt/clean-pathspec-filter-then-lstat later to maint).
+
+ * Recent "git prune" traverses young unreachable objects to safekeep
+   old objects in the reachability chain from them, which sometimes
+   caused error messages that are unnecessarily alarming.
+   (merge ce4e7b2 jk/squelch-missing-link-warning-for-unreachable later to maint).
+
+ * The configuration reader/writer uses mmap(2) interface to access
+   the files; when we find a directory, it barfed with "Out of memory?".
+   (merge 9ca0aaf jk/diagnose-config-mmap-failure later to maint).
+
+ * "color.diff.plain" was a misnomer; give it 'color.diff.context' as
+   a more logical synonym.
+   (merge 8dbf3eb jk/color-diff-plain-is-context later to maint).
+
+ * The setup code used to die when core.bare and core.worktree are set
+   inconsistently, even for commands that do not need working tree.
+   (merge fada767 jk/die-on-bogus-worktree-late later to maint).
+
+ * Recent Mac OS X updates breaks the logic to detect that the machine
+   is on the AC power in the sample pre-auto-gc script.
+   (merge c54c7b3 pa/auto-gc-mac-osx later to maint).
+
+ * "git commit --cleanup=scissors" was not careful enough to protect
+   against getting fooled by a line that looked like scissors.
+   (merge fbfa097 sg/commit-cleanup-scissors later to maint).
+
+ * "Have we lost a race with competing repack?" check was too
+   expensive, especially while receiving a huge object transfer
+   that runs index-pack (e.g. "clone" or "fetch").
+   (merge 0eeb077 jk/index-pack-reduce-recheck later to maint).
+
+ * The tcsh completion writes a bash scriptlet but that would have
+   failed for users with noclobber set.
+   (merge 0b1f688 af/tcsh-completion-noclobber later to maint).
+
+ * "git for-each-ref" reported "missing object" for 0{40} when it
+   encounters a broken ref.  The lack of object whose name is 0{40} is
+   not the problem; the ref being broken is.
+   (merge 501cf47 mh/reporting-broken-refs-from-for-each-ref later to maint).
+
+ * Various fixes around "git am" that applies a patch to a history
+   that is not there yet.
+   (merge 6ea3b67 pt/am-abort-fix later to maint).
+
+ * "git fsck" used to ignore missing or invalid objects recorded in reflog.
+   (merge 19bf6c9 mh/fsck-reflog-entries later to maint).
+
+ * "git format-patch --ignore-if-upstream A..B" did not like to be fed
+   tags as boundary commits.
+   (merge 9b7a61d jc/do-not-feed-tags-to-clear-commit-marks later to maint).
+
+ * "git fetch --depth=<depth>" and "git clone --depth=<depth>" issued
+   a shallow transfer request even to an upload-pack that does not
+   support the capability.
+   (merge eb86a50 me/fetch-into-shallow-safety later to maint).
+
+ * "git rebase" did not exit with failure when format-patch it invoked
+   failed for whatever reason.
+   (merge 60d708b cb/rebase-am-exit-code later to maint).
+
+ * Fix a small bug in our use of umask() return value.
+   (merge 3096b2e jk/fix-refresh-utime later to maint).
+
+ * An ancient test framework enhancement to allow color was not
+   entirely correct; this makes it work even when tput needs to read
+   from the ~/.terminfo under the user's real HOME directory.
+   (merge d5c1b7c rh/test-color-avoid-terminfo-in-original-home later to maint).
+
+ * A minor bugfix when pack bitmap is used with "rev-list --count".
+   (merge c8a70d3 jk/rev-list-no-bitmap-while-pruning later to maint).
+
+ * "git config" failed to update the configuration file when the
+   underlying filesystem is incapable of renaming a file that is still
+   open.
+   (merge 7a64592 kb/config-unmap-before-renaming later to maint).
+
+ * Avoid possible ssize_t to int truncation.
+   (merge 6c8afe4 mh/strbuf-read-file-returns-ssize-t later to maint).
+
+ * When you say "!<ENTER>" while running say "git log", you'd confuse
+   yourself in the resulting shell, that may look as if you took
+   control back to the original shell you spawned "git log" from but
+   that isn't what is happening.  To that new shell, we leaked
+   GIT_PAGER_IN_USE environment variable that was meant as a local
+   communication between the original "Git" and subprocesses that was
+   spawned by it after we launched the pager, which caused many
+   "interesting" things to happen, e.g. "git diff | cat" still paints
+   its output in color by default.
+
+   Stop leaking that environment variable to the pager's half of the
+   fork; we only need it on "Git" side when we spawn the pager.
+   (merge 124b519 jc/unexport-git-pager-in-use-in-pager later to maint).
+
+ * Abandoning an already applied change in "git rebase -i" with
+   "--continue" left CHERRY_PICK_HEAD and confused later steps.
+   (merge 0e0aff4 js/rebase-i-clean-up-upon-continue-to-skip later to maint).
+
+ * We used to ask libCURL to use the most secure authentication method
+   available when talking to an HTTP proxy only when we were told to
+   talk to one via configuration variables.  We now ask libCURL to
+   always use the most secure authentication method, because the user
+   can tell libCURL to use an HTTP proxy via an environment variable
+   without using configuration variables.
+   (merge 5841520 et/http-proxyauth later to maint).
+
+ * A fix to a minor regression to "git fsck" in v2.2 era that started
+   complaining about a body-less tag object when it lacks a separator
+   empty line after its header to separate it with a non-existent body.
+   (merge 84d18c0 jc/fsck-retire-require-eoh later to maint).
+
+ * Code cleanups and documentation updates.
+   (merge 0269f96 mm/usage-log-l-can-take-regex later to maint).
+   (merge 64f2589 nd/t1509-chroot-test later to maint).

+Git v2.5.1 Release Notes
+========================
+
+Fixes since v2.5
+----------------
+
+ * Running an aliased command from a subdirectory when the .git thing
+   in the working tree is a gitfile pointing elsewhere did not work.
+
+ * Often a fast-import stream builds a new commit on top of the
+   previous commit it built, and it often unconditionally emits a
+   "from" command to specify the first parent, which can be omitted in
+   such a case.  This caused fast-import to forget the tree of the
+   previous commit and then re-read it from scratch, which was
+   inefficient.  Optimize for this common case.
+
+ * The "rev-parse --parseopt" mode parsed the option specification
+   and the argument hint in a strange way to allow '=' and other
+   special characters in the option name while forbidding them from
+   the argument hint.  This made it impossible to define an option
+   like "--pair <key>=<value>" with "pair=key=value" specification,
+   which instead would have defined a "--pair=key <value>" option.
+
+ * A "rebase" replays changes of the local branch on top of something
+   else, as such they are placed in stage #3 and referred to as
+   "theirs", while the changes in the new base, typically a foreign
+   work, are placed in stage #2 and referred to as "ours".  Clarify
+   the "checkout --ours/--theirs".
+
+ * An experimental "untracked cache" feature used uname(2) in a
+   slightly unportable way.
+
+ * "sparse checkout" misbehaved for a path that is excluded from the
+   checkout when switching between branches that differ at the path.
+
+ * The low-level "git send-pack" did not honor 'user.signingkey'
+   configuration variable when sending a signed-push.
+
+ * An attempt to delete a ref by pushing into a repository whose HEAD
+   symbolic reference points at an unborn branch that cannot be
+   created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
+   points at refs/heads/a) failed.
+
+ * "git subtree" (in contrib/) depended on "git log" output to be
+   stable, which was a no-no.  Apply a workaround to force a
+   particular date format.
+
+ * "git clone $URL" in recent releases of Git contains a regression in
+   the code that invents a new repository name incorrectly based on
+   the $URL.  This has been corrected.
+   (merge db2e220 jk/guess-repo-name-regression-fix later to maint).
+
+ * Running tests with the "-x" option to make them verbose had some
+   unpleasant interactions with other features of the test suite.
+   (merge 9b5fe78 jk/test-with-x later to maint).
+
+ * "git pull" in recent releases of Git has a regression in the code
+   that allows custom path to the --upload-pack=<program>.  This has
+   been corrected.
+
+ * pipe() emulation used in Git for Windows looked at a wrong variable
+   when checking for an error from an _open_osfhandle() call.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git v2.5.2 Release Notes
+========================
+
+Fixes since v2.5.1
+------------------
+
+ * "git init empty && git -C empty log" said "bad default revision 'HEAD'",
+   which was found to be a bit confusing to new users.
+
+ * The "interpret-trailers" helper mistook a multi-paragraph title of
+   a commit log message with a colon in it as the end of the trailer
+   block.
+
+ * When re-priming the cache-tree opportunistically while committing
+   the in-core index as-is, we mistakenly invalidated the in-core
+   index too aggressively, causing the experimental split-index code
+   to unnecessarily rewrite the on-disk index file(s).
+
+ * "git archive" did not use zip64 extension when creating an archive
+   with more than 64k entries, which nobody should need, right ;-)?
+
+ * The code in "multiple-worktree" support that attempted to recover
+   from an inconsistent state updated an incorrect file.
+
+ * "git rev-list" does not take "--notes" option, but did not complain
+   when one is given.
+
+ * Because the configuration system does not allow "alias.0foo" and
+   "pager.0foo" as the configuration key, the user cannot use '0foo'
+   as a custom command name anyway, but "git 0foo" tried to look these
+   keys up and emitted useless warnings before saying '0foo is not a
+   git command'.  These warning messages have been squelched.
+
+ * We recently rewrote one of the build scripts in Perl, which made it
+   necessary to have Perl to build Git.  Reduced Perl dependency by
+   rewriting it again using sed.
+
+ * t1509 test that requires a dedicated VM environment had some
+   bitrot, which has been corrected.
+
+ * strbuf_read() used to have one extra iteration (and an unnecessary
+   strbuf_grow() of 8kB), which was eliminated.
+
+ * The codepath to produce error messages had a hard-coded limit to
+   the size of the message, primarily to avoid memory allocation while
+   calling die().
+
+ * When trying to see that an object does not exist, a state errno
+   leaked from our "first try to open a packfile with O_NOATIME and
+   then if it fails retry without it" logic on a system that refuses
+   O_NOATIME.  This confused us and caused us to die, saying that the
+   packfile is unreadable, when we should have just reported that the
+   object does not exist in that packfile to the caller.
+
+ * An off-by-one error made "git remote" to mishandle a remote with a
+   single letter nickname.
+
+ * A handful of codepaths that used to use fixed-sized arrays to hold
+   pathnames have been corrected to use strbuf and other mechanisms to
+   allow longer pathnames without fearing overflows.
+
+Also contains typofixes, documentation updates and trivial code
+clean-ups.

+Git 2.6 Release Notes
+=====================
+
+Updates since v2.5
+------------------
+
+UI, Workflows & Features
+
+ * An asterisk as a substring (as opposed to the entirety) of a path
+   component for both side of a refspec, e.g.
+   "refs/heads/o*:refs/remotes/heads/i*", is now allowed.
+
+ * New userdiff pattern definition for fountain screenwriting markup
+   format has been added.
+
+ * "git log" and friends learned a new "--date=format:..." option to
+   format timestamps using system's strftime(3).
+
+ * "git fast-import" learned to respond to the get-mark command via
+   its cat-blob-fd interface.
+
+ * "git rebase -i" learned "drop commit-object-name subject" command
+   as another way to skip replaying of a commit.
+
+ * A new configuration variable can enable "--follow" automatically
+   when "git log" is run with one pathspec argument.
+
+ * "git status" learned to show a more detailed information regarding
+   the "rebase -i" session in progress.
+
+ * "git cat-file" learned "--batch-all-objects" option to enumerate all
+   available objects in the repository more quickly than "rev-list
+   --all --objects" (the output includes unreachable objects, though).
+
+ * "git fsck" learned to ignore errors on a set of known-to-be-bad
+   objects, and also allows the warning levels of various kinds of
+   non-critical breakages to be tweaked.
+
+ * "git rebase -i"'s list of todo is made configurable.
+
+ * "git send-email" now performs alias-expansion on names that are
+   given via --cccmd, etc.
+
+ * An environment variable GIT_REPLACE_REF_BASE tells Git to look into
+   refs hierarchy other than refs/replace/ for the object replacement
+   data.
+
+ * Allow untracked cache (experimental) to be used when sparse
+   checkout (experimental) is also in use.
+
+ * "git pull --rebase" has been taught to pay attention to
+   rebase.autostash configuration.
+
+ * The command-line completion script (in contrib/) has been updated.
+
+ * A negative !ref entry in multi-value transfer.hideRefs
+   configuration can be used to say "don't hide this one".
+
+ * After "git am" without "-3" stops, running "git am -3" pays attention
+   to "-3" only for the patch that caused the original invocation
+   to stop.
+
+ * When linked worktree is used, simultaneous "notes merge" instances
+   for the same ref in refs/notes/* are prevented from stomping on
+   each other.
+
+ * "git send-email" learned a new option --smtp-auth to limit the SMTP
+   AUTH mechanisms to be used to a subset of what the system library
+   supports.
+
+ * A new configuration variable http.sslVersion can be used to specify
+   what specific version of SSL/TLS to use to make a connection.
+
+ * "git notes merge" can be told with "--strategy=<how>" option how to
+   automatically handle conflicts; this can now be configured by
+   setting notes.mergeStrategy configuration variable.
+
+ * "git log --cc" did not show any patch, even though most of the time
+   the user meant "git log --cc -p -m" to see patch output for commits
+   with a single parent, and combined diff for merge commits.  The
+   command is taught to DWIM "--cc" (without "--raw" and other forms
+   of output specification) to "--cc -p -m".
+
+ * "git config --list" output was hard to parse when values consist of
+   multiple lines.  "--name-only" option is added to help this.
+
+ * A handful of usability & cosmetic fixes to gitk and l10n updates.
+
+ * A completely empty e-mail address <> is now allowed in the authors
+   file used by git-svn, to match the way it accepts the output from
+   authors-prog.
+
+
+Performance, Internal Implementation, Development Support etc.
+
+ * In preparation for allowing different "backends" to store the refs
+   in a way different from the traditional "one ref per file in
+   $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage,
+   direct filesystem access to ref-like things like CHERRY_PICK_HEAD
+   from scripts and programs has been reduced.
+
+ * Computation of untracked status indicator by bash prompt
+   script (in contrib/) has been optimized.
+
+ * Memory use reduction when commit-slab facility is used to annotate
+   sparsely (which is not recommended in the first place).
+
+ * Clean up refs API and make "git clone" less intimate with the
+   implementation detail.
+
+ * "git pull" was reimplemented in C.
+
+ * The packet tracing machinery allows to capture an incoming pack
+   data to a file for debugging.
+
+ * Move machinery to parse human-readable scaled numbers like 1k, 4M,
+   and 2G as an option parameter's value from pack-objects to
+   parse-options API, to make it available to other codepaths.
+
+ * "git verify-tag" and "git verify-commit" have been taught to share
+   more code, and then learned to optionally show the verification
+   message from the underlying GPG implementation.
+
+ * Various enhancements around "git am" reading patches generated by
+   foreign SCM have been made.
+
+ * Ref listing by "git branch -l" and "git tag -l" commands has
+   started to be rebuilt, based on the for-each-ref machinery.
+
+ * The code to perform multi-tree merges has been taught to repopulate
+   the cache-tree upon a successful merge into the index, so that
+   subsequent "diff-index --cached" (hence "status") and "write-tree"
+   (hence "commit") will go faster.
+
+   The same logic in "git checkout" may now be removed, but that is a
+   separate issue.
+
+ * Tests that assume how reflogs are represented on the filesystem too
+   much have been corrected.
+
+ * "git am" has been rewritten in "C".
+
+ * git_path() and mkpath() are handy helper functions but it is easy
+   to misuse, as the callers need to be careful to keep the number of
+   active results below 4.  Their uses have been reduced.
+
+ * The "lockfile" API has been rebuilt on top of a new "tempfile" API.
+
+ * To prepare for allowing a different "ref" backend to be plugged in
+   to the system, update_ref()/delete_ref() have been taught about
+   ref-like things like MERGE_HEAD that are per-worktree (they will
+   always be written to the filesystem inside $GIT_DIR).
+
+ * The gitmodules API that is accessed from the C code learned to
+   cache stuff lazily.
+
+
+Also contains various documentation updates and code clean-ups.
+
+
+Fixes since v2.5
+----------------
+
+Unless otherwise noted, all the fixes since v2.5 in the maintenance
+track are contained in this release (see the maintenance releases'
+notes for details).
+
+ * "git subtree" (in contrib/) depended on "git log" output to be
+   stable, which was a no-no.  Apply a workaround to force a
+   particular date format.
+   (merge e7aac44 da/subtree-date-confusion later to maint).
+
+ * An attempt to delete a ref by pushing into a repository whose HEAD
+   symbolic reference points at an unborn branch that cannot be
+   created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD
+   points at refs/heads/a) failed.
+   (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint).
+
+ * The low-level "git send-pack" did not honor 'user.signingkey'
+   configuration variable when sending a signed-push.
+   (merge d830d39 db/send-pack-user-signingkey later to maint).
+
+ * "sparse checkout" misbehaved for a path that is excluded from the
+   checkout when switching between branches that differ at the path.
+   (merge 7d78241 as/sparse-checkout-removal later to maint).
+
+ * An experimental "untracked cache" feature used uname(2) in a
+   slightly unportable way.
+   (merge 100e433 cb/uname-in-untracked later to maint).
+
+ * A "rebase" replays changes of the local branch on top of something
+   else, as such they are placed in stage #3 and referred to as
+   "theirs", while the changes in the new base, typically a foreign
+   work, are placed in stage #2 and referred to as "ours".  Clarify
+   the "checkout --ours/--theirs".
+   (merge f303016 se/doc-checkout-ours-theirs later to maint).
+
+ * The "rev-parse --parseopt" mode parsed the option specification
+   and the argument hint in a strange way to allow '=' and other
+   special characters in the option name while forbidding them from
+   the argument hint.  This made it impossible to define an option
+   like "--pair <key>=<value>" with "pair=key=value" specification,
+   which instead would have defined a "--pair=key <value>" option.
+   (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint).
+
+ * Often a fast-import stream builds a new commit on top of the
+   previous commit it built, and it often unconditionally emits a
+   "from" command to specify the first parent, which can be omitted in
+   such a case.  This caused fast-import to forget the tree of the
+   previous commit and then re-read it from scratch, which was
+   inefficient.  Optimize for this common case.
+   (merge 0df3245 mh/fast-import-optimize-current-from later to maint).
+
+ * Running an aliased command from a subdirectory when the .git thing
+   in the working tree is a gitfile pointing elsewhere did not work.
+   (merge d95138e nd/export-worktree later to maint).
+
+ * "Is this subdirectory a separate repository that should not be
+   touched?" check "git clean" was inefficient.  This was replaced
+   with a more optimized check.
+   (merge fbf2fec ee/clean-remove-dirs later to maint).
+
+ * The "new-worktree-mode" hack in "checkout" that was added in
+   nd/multiple-work-trees topic has been removed by updating the
+   implementation of new "worktree add".
+   (merge 65f9b75 es/worktree-add-cleanup later to maint).
+
+ * Remove remaining cruft from  "git checkout --to", which
+   transitioned to "git worktree add".
+   (merge 114ff88 es/worktree-add later to maint).
+
+ * An off-by-one error made "git remote" to mishandle a remote with a
+   single letter nickname.
+   (merge bc598c3 mh/get-remote-group-fix later to maint).
+
+ * "git clone $URL", when cloning from a site whose sole purpose is to
+   host a single repository (hence, no path after <scheme>://<site>/),
+   tried to use the site name as the new repository name, but did not
+   remove username or password when <site> part was of the form
+   <user>@<pass>:<host>.  The code is taught to redact these.
+   (merge adef956 ps/guess-repo-name-at-root later to maint).
+
+ * Running tests with the "-x" option to make them verbose had some
+   unpleasant interactions with other features of the test suite.
+   (merge 9b5fe78 jk/test-with-x later to maint).
+
+ * t1509 test that requires a dedicated VM environment had some
+   bitrot, which has been corrected.
+   (merge faacc5a ps/t1509-chroot-test-fixup later to maint).
+
+ * "git pull" in recent releases of Git has a regression in the code
+   that allows custom path to the --upload-pack=<program>.  This has
+   been corrected.
+
+   Note that this is irrelevant for 'master' with "git pull" rewritten
+   in C.
+   (merge 13e0e28 mm/pull-upload-pack later to maint).
+
+ * When trying to see that an object does not exist, a state errno
+   leaked from our "first try to open a packfile with O_NOATIME and
+   then if it fails retry without it" logic on a system that refuses
+   O_NOATIME.  This confused us and caused us to die, saying that the
+   packfile is unreadable, when we should have just reported that the
+   object does not exist in that packfile to the caller.
+   (merge dff6f28 cb/open-noatime-clear-errno later to maint).
+
+ * The codepath to produce error messages had a hard-coded limit to
+   the size of the message, primarily to avoid memory allocation while
+   calling die().
+   (merge f4c3edc jk/long-error-messages later to maint).
+
+ * strbuf_read() used to have one extra iteration (and an unnecessary
+   strbuf_grow() of 8kB), which was eliminated.
+   (merge 3ebbd00 jh/strbuf-read-use-read-in-full later to maint).
+
+ * We rewrote one of the build scripts in Perl but this reimplements
+   in Bourne shell.
+   (merge 57cee8a sg/help-group later to maint).
+
+ * The experimental untracked-cache feature were buggy when paths with
+   a few levels of subdirectories are involved.
+   (merge 73f9145 dt/untracked-subdir later to maint).
+
+ * "interpret-trailers" helper mistook a single-liner log message that
+   has a colon as the end of existing trailer.
+
+ * The "interpret-trailers" helper mistook a multi-paragraph title of
+   a commit log message with a colon in it as the end of the trailer
+   block.
+   (merge 5c99995 cc/trailers-corner-case-fix later to maint).
+
+ * "git describe" without argument defaulted to describe the HEAD
+   commit, but "git describe --contains" didn't.  Arguably, in a
+   repository used for active development, such defaulting would not
+   be very useful as the tip of branch is typically not tagged, but it
+   is better to be consistent.
+   (merge 2bd0706 sg/describe-contains later to maint).
+
+ * The client side codepaths in "git push" have been cleaned up
+   and the user can request to perform an optional "signed push",
+   i.e. sign only when the other end accepts signed push.
+   (merge 68c757f db/push-sign-if-asked later to maint).
+
+ * Because the configuration system does not allow "alias.0foo" and
+   "pager.0foo" as the configuration key, the user cannot use '0foo'
+   as a custom command name anyway, but "git 0foo" tried to look these
+   keys up and emitted useless warnings before saying '0foo is not a
+   git command'.  These warning messages have been squelched.
+   (merge 9e9de18 jk/fix-alias-pager-config-key-warnings later to maint).
+
+ * "git rev-list" does not take "--notes" option, but did not complain
+   when one is given.
+   (merge 2aea7a5 jk/rev-list-has-no-notes later to maint).
+
+ * When re-priming the cache-tree opportunistically while committing
+   the in-core index as-is, we mistakenly invalidated the in-core
+   index too aggressively, causing the experimental split-index code
+   to unnecessarily rewrite the on-disk index file(s).
+   (merge 475a344 dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update later to maint).
+
+ * "git archive" did not use zip64 extension when creating an archive
+   with more than 64k entries, which nobody should need, right ;-)?
+   (merge 88329ca rs/archive-zip-many later to maint).
+
+ * The code in "multiple-worktree" support that attempted to recover
+   from an inconsistent state updated an incorrect file.
+   (merge 82fde87 nd/fixup-linked-gitdir later to maint).
+
+ * On case insensitive systems, "git p4" did not work well with client
+   specs.
+
+ * "git init empty && git -C empty log" said "bad default revision 'HEAD'",
+   which was found to be a bit confusing to new users.
+   (merge ce11360 jk/log-missing-default-HEAD later to maint).
+
+ * Recent versions of scripted "git am" has a performance regression in
+   "git am --skip" codepath, which no longer exists in the built-in
+   version on the 'master' front.  Fix the regression in the last
+   scripted version that appear in 2.5.x maintenance track and older.
+   (merge b9d6689 js/maint-am-skip-performance-regression later to maint).
+
+ * The branch descriptions that are set with "git branch --edit-description"
+   option were used in many places but they weren't clearly documented.
+   (merge 561d2b7 po/doc-branch-desc later to maint).
+
+ * Code cleanups and documentation updates.
+   (merge 1c601af es/doc-clean-outdated-tools later to maint).

+(0) Decide what to base your work on.
+
+In general, always base your work on the oldest branch that your
+change is relevant to.
+
+ - A bugfix should be based on 'maint' in general. If the bug is not
+   present in 'maint', base it on 'master'. For a bug that's not yet
+   in 'master', find the topic that introduces the regression, and
+   base your work on the tip of the topic.
+
+ - A new feature should be based on 'master' in general. If the new
+   feature depends on a topic that is in 'pu', but not in 'master',
+   base your work on the tip of that topic.
+
+ - Corrections and enhancements to a topic not yet in 'master' should
+   be based on the tip of that topic. If the topic has not been merged
+   to 'next', it's alright to add a note to squash minor corrections
+   into the series.
+
+ - In the exceptional case that a new feature depends on several topics
+   not in 'master', start working on 'next' or 'pu' privately and send
+   out patches for discussion. Before the final merge, you may have to
+   wait until some of the dependent topics graduate to 'master', and
+   rebase your work.
+
+ - Some parts of the system have dedicated maintainers with their own
+   repositories (see the section "Subsystems" below).  Changes to
+   these parts should be based on their trees.
+
+To find the tip of a topic branch, run "git log --first-parent
+master..pu" and look for the merge commit. The second parent of this
+commit is the tip of the topic branch.

+differs substantially from the prior version, are all good things
+to have.
+
+Make sure that you have tests for the bug you are fixing.  See
+t/README for guidance.
+
+When adding a new feature, make sure that you have new tests to show
+the feature triggers the new behaviour when it should, and to show the
+feature does not trigger when it shouldn't.  Also make sure that the
+test suite passes after your commit.  Do not forget to update the
+documentation to describe the updated behaviour.
+
+Speaking of the documentation, it is currently a liberal mixture of US
+and UK English norms for spelling and grammar, which is somewhat
+unfortunate.  A huge patch that touches the files all over the place
+only to correct the inconsistency is not welcome, though.  Potential
+clashes with other changes that can result from such a patch are not
+worth it.  We prefer to gradually reconcile the inconsistencies in
+favor of US English, with small and easily digestible patches, as a
+side effect of doing some other real work in the vicinity (e.g.
+rewriting a paragraph for clarity, while turning en_UK spelling to
+en_US).  Obvious typographical fixes are much more welcomed ("teh ->
+"the"), preferably submitted as independent patches separate from
+other documentation changes.
+
+Oh, another thing.  We are picky about whitespaces.  Make sure your
 changes do not trigger errors with the sample pre-commit hook shipped
 in templates/hooks--pre-commit.  To help ensure this does not happen,
 run git diff --check on your changes before you commit.
 
 
-(2) Generate your patch using git tools out of your commits.
+(2) Describe your changes well.
+
+The first line of the commit message should be a short description (50
+characters is the soft limit, see DISCUSSION in git-commit(1)), and
+should skip the full stop.  It is also conventional in most cases to
+prefix the first line with "area: " where the area is a filename or
+identifier for the general area of the code being modified, e.g.
+
+  . archive: ustar header checksum is computed unsigned
+  . git-cherry-pick.txt: clarify the use of revision range notation
+
+If in doubt which identifier to use, run "git log --no-merges" on the
+files you are modifying to see the current conventions.
+
+The body should provide a meaningful commit message, which:
+
+  . explains the problem the change tries to solve, iow, what is wrong
+    with the current code without the change.
+
+  . justifies the way the change solves the problem, iow, why the
+    result with the change is better.
+
+  . alternate solutions considered but discarded, if any.
+
+Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
+instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
+to do frotz", as if you are giving orders to the codebase to change
+its behaviour.  Try to make sure your explanation can be understood
+without external resources. Instead of giving a URL to a mailing list
+archive, summarize the relevant points of the discussion.

+
+ - gitk-git/ comes from Paul Mackerras's gitk project:

+ - po/ comes from the localization coordinator, Jiang Xin:

-* Empty context lines that do not have _any_ whitespace.
+Patches to these parts should be based on their trees.
 
-* Non empty context lines that have one extra whitespace at the
-  beginning.
+------------------------------------------------
+An ideal patch flow
+
+Here is an ideal patch flow for this project the current maintainer
+suggests to the contributors:
+
+ (0) You come up with an itch.  You code it up.
+
+ (1) Send it to the list and cc people who may need to know about
+     the change.
+
+     The people who may need to know are the ones whose code you
+     are butchering.  These people happen to be the ones who are
+     most likely to be knowledgeable enough to help you, but
+     they have no obligation to help you (i.e. you ask for help,
+     don't demand).  "git log -p -- $area_you_are_modifying" would
+     help you find out who they are.
 
-One test you could do yourself if your MUA is set up correctly is:
+ (2) You get comments and suggestions for improvements.  You may
+     even get them in a "on top of your change" patch form.
 
-* Send the patch to yourself, exactly the way you would, except
-  To: and Cc: lines, which would not contain the list and
-  maintainer address.
+ (3) Polish, refine, and re-send to the list and the people who
+     spend their time to improve your patch.  Go back to step (2).
 
-* Save that patch to a file in UNIX mailbox format.  Call it say
-  a.patch.
+ (4) The list forms consensus that the last round of your patch is
+     good.  Send it to the maintainer and cc the list.
+
+ (5) A topic branch is created with the patch and is merged to 'next',
+     and cooked further and eventually graduates to 'master'.
+
+In any time between the (2)-(3) cycle, the maintainer may pick it up
+from the list and queue it to 'pu', in order to make it easier for
+people play with it without having to pick up and apply the patch to
+their trees themselves.
+
+------------------------------------------------
+Know the status of your patch after submission
 
-* Try to apply to the tip of the "master" branch from the
-  git.git public repository:
+* You can use Git itself to find out when your patch is merged in
+  master. 'git pull --rebase' will automatically skip already-applied
+  patches, and will let you know. This works only if you rebase on top
+  of the branch in which your patch has been merged (i.e. it will not
+  tell you if your patch is merged in pu if you rebase on top of
+  master).
 
-    $ git fetch http://kernel.org/pub/scm/git/git.git master:test-apply
-    $ git checkout test-apply
-    $ git reset --hard
-    $ git applymbox a.patch
+* Read the Git mailing list, the maintainer regularly posts messages
+  entitled "What's cooking in git.git" and "What's in git.git" giving
+  the status of various proposed changes.
 
-If it does not apply correctly, there can be various reasons.
+------------------------------------------------
+MUA specific hints
 
-* Your patch itself does not apply cleanly.  That is _bad_ but
-  does not have much to do with your MUA.  Please rebase the
-  patch appropriately.
+Some of patches I receive or pick up from the list share common
+patterns of breakage.  Please make sure your MUA is set up
+properly not to corrupt whitespaces.
 
-* Your MUA corrupted your patch; applymbox would complain that
-  the patch does not apply.  Look at .dotest/ subdirectory and
-  see what 'patch' file contains and check for the common
-  corruption patterns mentioned above.
+See the DISCUSSION section of git-format-patch(1) for hints on
+checking your patch by mailing it to yourself and applying with
+git-am(1).
 
-* While you are at it, check what are in 'info' and
-  'final-commit' files as well.  If what is in 'final-commit' is
-  not exactly what you would want to see in the commit log
-  message, it is very likely that your maintainer would end up
-  hand editing the log message when he applies your patch.
-  Things like "Hi, this is my first patch.\n", if you really
-  want to put in the patch e-mail, should come after the
-  three-dash line that signals the end of the commit message.
+While you are at it, check the resulting commit log message from
+a trial run of applying the patch.  If what is in the resulting
+commit is not exactly what you would want to see, it is very
+likely that your maintainer would end up hand editing the log

-3) In the main Thunderbird window, _before_ you open the compose window
-for the patch, use Tools->about:config to set the following to the
-indicated values:

-
-5) In the external editor window, read in the patch file and exit the
-editor normally.
-
-6) Back in the compose window: Add whatever other text you wish to the
-message, complete the addressing and subject fields, and press send.

+	has A and then B, and the commit changes it to B and then
+	A), the traditional 'blame' algorithm notices only half of
+	the movement and typically blames the lines that were moved
+	up (i.e. B) to the parent and assigns blame to the lines that
+	were moved down (i.e. A) to the child commit.  With this
+	option, both groups of lines are blamed on the parent by
+	running extra passes of inspection.
++
+<num> is optional but it is the lower bound on the number of
+alphanumeric characters that Git must detect as moving/copying
+within a file for it to associate those lines with the parent
+commit. The default value is 20.
+
+-C|<num>|::
+	In addition to `-M`, detect lines moved or copied from other
+	files that were modified in the same commit.  This is
+	useful when you reorganize your program and move code
+	around across files.  When this option is given twice,
+	the command additionally looks for copies from other
+	files in the commit that creates the file. When this
+	option is given three times, the command additionally
+	looks for copies from other files in any commit.
++
+<num> is optional but it is the lower bound on the number of
+alphanumeric characters that Git must detect as moving/copying
+between files for it to associate those lines with the parent
+commit. And the default value is 40. If there are more than one
+`-C` options given, the <num> argument of the last `-C` will
+take effect.

 You can have `[section]` if you have `[section "subsection"]`, but you
 don't need to.
 
-There is also (case insensitive) alternative `[section.subsection]` syntax.
-In this syntax subsection names follow the same restrictions as for section
-name.
-
-All the other lines are recognized as setting variables, in the form
-'name = value'.  If there is no equal sign on the line, the entire line
-is taken as 'name' and the variable is recognized as boolean "true".
-The variable names are case-insensitive and only alphanumeric
-characters and '`-`' are allowed.  There can be more than one value
-for a given variable; we say then that variable is multivalued.
-
-Leading and trailing whitespace in a variable value is discarded.
-Internal whitespace within a variable value is retained verbatim.
-
-The values following the equals sign in variable assign are all either
-a string, an integer, or a boolean.  Boolean values may be given as yes/no,
-0/1 or true/false.  Case is not significant in boolean values, when
-converting value to the canonical form using '--bool' type specifier;
-`git-config` will ensure that the output is "true" or "false".

+Includes
+~~~~~~~~
+
+You can include one config file from another by setting the special
+`include.path` variable to the name of the file to be included. The
+included file is expanded immediately, as if its contents had been
+found at the location of the include directive. If the value of the
+`include.path` variable is a relative path, the path is considered to be
+relative to the configuration file in which the include directive was
+found. The value of `include.path` is subject to tilde expansion: `~/`
+is expanded to the value of `$HOME`, and `~user/` to the specified
+user's home directory. See below for examples.

+Values
+~~~~~~
+
+Values of many variables are treated as a simple string, but there
+are variables that take values of specific types and there are rules
+as to how to spell them.
+
+boolean::
+
+       When a variable is said to take a boolean value, many
+       synonyms are accepted for 'true' and 'false'; these are all
+       case-insensitive.
+
+       true;; Boolean true can be spelled as `yes`, `on`, `true`,
+		or `1`.  Also, a variable defined without `= <value>`
+		is taken as true.
+
+       false;; Boolean false can be spelled as `no`, `off`,
+		`false`, or `0`.
++
+When converting value to the canonical form using '--bool' type
+specifier; 'git config' will ensure that the output is "true" or
+"false" (spelled in lowercase).
+
+integer::
+       The value for many variables that specify various sizes can
+       be suffixed with `k`, `M`,... to mean "scale the number by
+       1024", "by 1024x1024", etc.
+
+color::
+       The value for a variables that takes a color is a list of
+       colors (at most two) and attributes (at most one), separated
+       by spaces.  The colors accepted are `normal`, `black`,
+       `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` and
+       `white`; the attributes are `bold`, `dim`, `ul`, `blink` and
+       `reverse`.  The first color given is the foreground; the
+       second is the background.  The position of the attribute, if
+       any, doesn't matter. Attributes may be turned off specifically
+       by prefixing them with `no` (e.g., `noreverse`, `noul`, etc).
++
+Colors (foreground and background) may also be given as numbers between
+0 and 255; these use ANSI 256-color mode (but note that not all
+terminals may support this).  If your terminal supports it, you may also
+specify 24-bit RGB values as hex, like `#ff0ab3`.
++
+The attributes are meant to be reset at the beginning of each item
+in the colored output, so setting color.decorate.branch to `black`
+will paint that branch name in a plain `black`, even if the previous
+thing on the same output line (e.g. opening parenthesis before the
+list of branch names in `log --decorate` output) is set to be
+painted with `bold` or some other attribute.

 core.fileMode::
-	If false, the executable bit differences between the index and
-	the working copy are ignored; useful on broken filesystems like FAT.
-	See gitlink:git-update-index[1]. True by default.
+	Tells Git if the executable bit of files in the working tree
+	is to be honored.
++
+Some filesystems lose the executable bit when a file that is
+marked as executable is checked out, or checks out an
+non-executable file with executable bit on.
+linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
+to see if it handles the executable bit correctly
+and this variable is automatically set as necessary.
++
+A repository, however, may be on a filesystem that handles
+the filemode correctly, and this variable is set to 'true'
+when created, but later may be made accessible from another
+environment that loses the filemode (e.g. exporting ext4 via
+CIFS mount, visiting a Cygwin created repository with
+Git for Windows or Eclipse).
+In such a case it may be necessary to set this variable to 'false'.
+See linkgit:git-update-index[1].
++
+The default is true (when core.filemode is not specified in the config file).
+
+core.ignoreCase::
+	If true, this option enables various workarounds to enable
+	Git to work better on filesystems that are not case sensitive,
+	like FAT. For example, if a directory listing finds
+	"makefile" when Git expects "Makefile", Git will assume
+	it is really the same file, and continue to remember it as
+	"Makefile".
++
+The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
+will probe and set core.ignoreCase true if appropriate when the repository
+is created.
+
+core.precomposeUnicode::
+	This option is only used by Mac OS implementation of Git.
+	When core.precomposeUnicode=true, Git reverts the unicode decomposition
+	of filenames done by Mac OS. This is useful when sharing a repository
+	between Mac OS and Linux or Windows.
+	(Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
+	When false, file names are handled fully transparent by Git,
+	which is backward compatible with older versions of Git.
+
+core.protectHFS::
+	If set to true, do not allow checkout of paths that would
+	be considered equivalent to `.git` on an HFS+ filesystem.
+	Defaults to `true` on Mac OS, and `false` elsewhere.
+
+core.protectNTFS::
+	If set to true, do not allow checkout of paths that would
+	cause problems with the NTFS filesystem, e.g. conflict with
+	8.3 "short" names.
+	Defaults to `true` on Windows, and `false` elsewhere.
+
+core.trustctime::
+	If false, the ctime differences between the index and the
+	working tree are ignored; useful when the inode change time
+	is regularly modified by something outside Git (file system
+	crawlers and some backup systems).
+	See linkgit:git-update-index[1]. True by default.
+
+core.checkStat::
+	Determines which stat fields to match between the index
+	and work tree. The user can set this to 'default' or
+	'minimal'. Default (or explicitly 'default'), is to check
+	all fields, including the sub-second part of mtime and ctime.
+
+core.quotePath::
+	The commands that output paths (e.g. 'ls-files',
+	'diff'), when not given the `-z` option, will quote
+	"unusual" characters in the pathname by enclosing the
+	pathname in a double-quote pair and with backslashes the
+	same way strings in C source code are quoted.  If this
+	variable is set to false, the bytes higher than 0x80 are
+	not quoted but output as verbatim.  Note that double
+	quote, backslash and control characters are always
+	quoted without `-z` regardless of the setting of this
+	variable.
+
+core.eol::
+	Sets the line ending type to use in the working directory for
+	files that have the `text` property set.  Alternatives are
+	'lf', 'crlf' and 'native', which uses the platform's native
+	line ending.  The default value is `native`.  See
+	linkgit:gitattributes[5] for more information on end-of-line
+	conversion.
+
+core.safecrlf::
+	If true, makes Git check if converting `CRLF` is reversible when
+	end-of-line conversion is active.  Git will verify if a command
+	modifies a file in the work tree either directly or indirectly.
+	For example, committing a file followed by checking out the
+	same file should yield the original file in the work tree.  If
+	this is not the case for the current setting of
+	`core.autocrlf`, Git will reject the file.  The variable can
+	be set to "warn", in which case Git will only warn about an
+	irreversible conversion but continue the operation.
++
+CRLF conversion bears a slight chance of corrupting data.
+When it is enabled, Git will convert CRLF to LF during commit and LF to
+CRLF during checkout.  A file that contains a mixture of LF and
+CRLF before the commit cannot be recreated by Git.  For text
+files this is the right thing to do: it corrects line endings
+such that we have only LF line endings in the repository.
+But for binary files that are accidentally classified as text the
+conversion can corrupt data.
++
+If you recognize such corruption early you can easily fix it by
+setting the conversion type explicitly in .gitattributes.  Right
+after committing you still have the original file in your work
+tree and this file is not yet corrupted.  You can explicitly tell
+Git that this file is binary and Git will handle the file
+appropriately.
++
+Unfortunately, the desired effect of cleaning up text files with
+mixed line endings and the undesired effect of corrupting binary
+files cannot be distinguished.  In both cases CRLFs are removed
+in an irreversible way.  For text files this is the right thing
+to do because CRLFs are line endings, while for binary files
+converting CRLFs corrupts data.
++
+Note, this safety check does not mean that a checkout will generate a
+file identical to the original file for a different setting of
+`core.eol` and `core.autocrlf`, but only for the current one.  For
+example, a text file with `LF` would be accepted with `core.eol=lf`
+and could later be checked out with `core.eol=crlf`, in which case the
+resulting file would contain `CRLF`, although the original file
+contained `LF`.  However, in both work trees the line endings would be
+consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
+file with mixed line endings would be reported by the `core.safecrlf`
+mechanism.
+
+core.autocrlf::
+	Setting this variable to "true" is almost the same as setting
+	the `text` attribute to "auto" on all files except that text
+	files are not guaranteed to be normalized: files that contain
+	`CRLF` in the repository will not be touched.  Use this
+	setting if you want to have `CRLF` line endings in your
+	working directory even though the repository does not have
+	normalized line endings.  This variable can be set to 'input',
+	in which case no output conversion is performed.
 
 core.symlinks::
 	If false, symbolic links are checked out as small plain files that
-	contain the link text. gitlink:git-update-index[1] and
-	gitlink:git-add[1] will not change the recorded type to regular

+If set to "auto", `git-commit` would select a character that is not
+the beginning character of any line in existing commit messages.
+
+core.packedRefsTimeout::
+	The length of time, in milliseconds, to retry when trying to
+	lock the `packed-refs` file. Value 0 means not to retry at
+	all; -1 means to try indefinitely. Default is 1000 (i.e.,
+	retry for 1 second).
+
+sequence.editor::
+	Text editor used by `git rebase -i` for editing the rebase instruction file.
+	The value is meant to be interpreted by the shell when it is used.
+	It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
+	When not configured the default commit message editor is used instead.
+
+core.pager::
+	Text viewer for use by Git commands (e.g., 'less').  The value
+	is meant to be interpreted by the shell.  The order of preference
+	is the `$GIT_PAGER` environment variable, then `core.pager`
+	configuration, then `$PAGER`, and then the default chosen at
+	compile time (usually 'less').
++
+When the `LESS` environment variable is unset, Git sets it to `FRX`
+(if `LESS` environment variable is set, Git does not change it at
+all).  If you want to selectively override Git's default setting
+for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
+be passed to the shell by Git, which will translate the final
+command to `LESS=FRX less -S`. The environment does not set the
+`S` option but the command line does, instructing less to truncate
+long lines. Similarly, setting `core.pager` to `less -+F` will
+deactivate the `F` option specified by the environment from the
+command-line, deactivating the "quit if one screen" behavior of
+`less`.  One can specifically activate some flags for particular
+commands: for example, setting `pager.blame` to `less -S` enables
+line truncation only for `git blame`.
++
+Likewise, when the `LV` environment variable is unset, Git sets it
+to `-c`.  You can override this setting by exporting `LV` with
+another value or setting `core.pager` to `lv +c`.
+
+core.whitespace::
+	A comma separated list of common whitespace problems to
+	notice.  'git diff' will use `color.diff.whitespace` to
+	highlight them, and 'git apply --whitespace=error' will
+	consider them as errors.  You can prefix `-` to disable
+	any of them (e.g. `-trailing-space`):
++
+* `blank-at-eol` treats trailing whitespaces at the end of the line
+  as an error (enabled by default).
+* `space-before-tab` treats a space character that appears immediately
+  before a tab character in the initial indent part of the line as an
+  error (enabled by default).
+* `indent-with-non-tab` treats a line that is indented with space
+  characters instead of the equivalent tabs as an error (not enabled by
+  default).
+* `tab-in-indent` treats a tab character in the initial indent part of
+  the line as an error (not enabled by default).
+* `blank-at-eof` treats blank lines added at the end of file as an error
+  (enabled by default).
+* `trailing-space` is a short-hand to cover both `blank-at-eol` and
+  `blank-at-eof`.
+* `cr-at-eol` treats a carriage-return at the end of line as
+  part of the line terminator, i.e. with it, `trailing-space`
+  does not trigger if the character before such a carriage-return
+  is not a whitespace (not enabled by default).
+* `tabwidth=<n>` tells how many character positions a tab occupies; this
+  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
+  errors. The default tab width is 8. Allowed values are 1 to 63.
+
+core.fsyncObjectFiles::
+	This boolean will enable 'fsync()' when writing object files.
++
+This is a total waste of time and effort on a filesystem that orders
+data writes properly, but can be useful for filesystems that do not use
+journalling (traditional UNIX filesystems) or that only journal metadata
+and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
+
+core.preloadIndex::
+	Enable parallel index preload for operations like 'git diff'
++
+This can speed up operations like 'git diff' and 'git status' especially
+on filesystems like NFS that have weak caching semantics and thus
+relatively high IO latencies.  When enabled, Git will do the
+index comparison to the filesystem data in parallel, allowing
+overlapping IO's.  Defaults to true.
+
+core.createObject::
+	You can set this to 'link', in which case a hardlink followed by
+	a delete of the source are used to make sure that object creation
+	will not overwrite existing objects.
++
+On some file system/operating system combinations, this is unreliable.
+Set this config setting to 'rename' there; However, This will remove the
+check that makes sure that existing object files will not get overwritten.
+
+core.notesRef::
+	When showing commit messages, also show notes which are stored in
+	the given ref.  The ref must be fully qualified.  If the given
+	ref does not exist, it is not an error but means that no
+	notes should be printed.
++
+This setting defaults to "refs/notes/commits", and it can be overridden by
+the 'GIT_NOTES_REF' environment variable.  See linkgit:git-notes[1].
+
+core.sparseCheckout::
+	Enable "sparse checkout" feature. See section "Sparse checkout" in
+	linkgit:git-read-tree[1] for more information.
+
+core.abbrev::
+	Set the length object names are abbreviated to.  If unspecified,
+	many commands abbreviate to 7 hexdigits, which may not be enough
+	for abbreviated object names to stay unique for sufficiently long
+	time.
+
+add.ignoreErrors::
+add.ignore-errors (deprecated)::
+	Tells 'git add' to continue adding files when some files cannot be
+	added due to indexing errors. Equivalent to the '--ignore-errors'
+	option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
+	as it does not follow the usual naming convention for configuration
+	variables.

+	Command aliases for the linkgit:git[1] command wrapper - e.g.

+"gitk --all --not ORIG_HEAD".  Note that shell commands will be
+executed from the top-level directory of a repository, which may
+not necessarily be the current directory.
+'GIT_PREFIX' is set as returned by running 'git rev-parse --show-prefix'
+from the original current directory. See linkgit:git-rev-parse[1].
+
+am.keepcr::
+	If true, git-am will call git-mailsplit for patches in mbox format
+	with parameter '--keep-cr'. In this case git-mailsplit will
+	not remove `\r` from lines ending with `\r\n`. Can be overridden
+	by giving '--no-keep-cr' from the command line.
+	See linkgit:git-am[1], linkgit:git-mailsplit[1].
+
+am.threeWay::
+	By default, `git am` will fail if the patch does not apply cleanly. When
+	set to true, this setting tells `git am` to fall back on 3-way merge if
+	the patch records the identity of blobs it is supposed to apply to and
+	we have those blobs available locally (equivalent to giving the `--3way`
+	option from the command line). Defaults to `false`.
+	See linkgit:git-am[1].
+
+apply.ignoreWhitespace::
+	When set to 'change', tells 'git apply' to ignore changes in
+	whitespace, in the same way as the '--ignore-space-change'
+	option.
+	When set to one of: no, none, never, false tells 'git apply' to
+	respect all whitespace differences.
+	See linkgit:git-apply[1].
 
 apply.whitespace::
-	Tells `git-apply` how to handle whitespaces, in the same way
-	as the '--whitespace' option. See gitlink:git-apply[1].
+	Tells 'git apply' how to handle whitespaces, in the same way
+	as the '--whitespace' option. See linkgit:git-apply[1].
+
+branch.autoSetupMerge::
+	Tells 'git branch' and 'git checkout' to set up new branches
+	so that linkgit:git-pull[1] will appropriately merge from the
+	starting point branch. Note that even if this option is not set,
+	this behavior can be chosen per-branch using the `--track`
+	and `--no-track` options. The valid settings are: `false` -- no
+	automatic setup is done; `true` -- automatic setup is done when the
+	starting point is a remote-tracking branch; `always` --
+	automatic setup is done when the starting point is either a
+	local branch or remote-tracking
+	branch. This option defaults to true.
+
+branch.autoSetupRebase::
+	When a new branch is created with 'git branch' or 'git checkout'
+	that tracks another branch, this variable tells Git to set
+	up pull to rebase instead of merge (see "branch.<name>.rebase").
+	When `never`, rebase is never automatically set to true.
+	When `local`, rebase is set to true for tracked branches of
+	other local branches.
+	When `remote`, rebase is set to true for tracked branches of
+	remote-tracking branches.
+	When `always`, rebase will be set to true for all tracking
+	branches.
+	See "branch.autoSetupMerge" for details on how to set up a
+	branch to track another branch.
+	This option defaults to never.
 
 branch.<name>.remote::
-	When in branch <name>, it tells `git fetch` which remote to fetch.
-	If this option is not given, `git fetch` defaults to remote "origin".
+	When on branch <name>, it tells 'git fetch' and 'git push'
+	which remote to fetch from/push to.  The remote to push to
+	may be overridden with `remote.pushDefault` (for all branches).
+	The remote to push to, for the current branch, may be further
+	overridden by `branch.<name>.pushRemote`.  If no remote is
+	configured, or if you are not on any branch, it defaults to
+	`origin` for fetching and `remote.pushDefault` for pushing.
+	Additionally, `.` (a period) is the current local repository
+	(a dot-repository), see `branch.<name>.merge`'s final note below.
+
+branch.<name>.pushRemote::
+	When on branch <name>, it overrides `branch.<name>.remote` for
+	pushing.  It also overrides `remote.pushDefault` for pushing
+	from branch <name>.  When you pull from one place (e.g. your
+	upstream) and push to another place (e.g. your own publishing
+	repository), you would want to set `remote.pushDefault` to
+	specify the remote to push to for all branches, and use this
+	option to override it for a specific branch.
 
 branch.<name>.merge::
-	When in branch <name>, it tells `git fetch` the default refspec to
-	be marked for merging in FETCH_HEAD. The value has exactly to match
-	a remote part of one of the refspecs which are fetched from the remote
-	given by "branch.<name>.remote".
-	The merge information is used by `git pull` (which at first calls
-	`git fetch`) to lookup the default branch for merging. Without
-	this option, `git pull` defaults to merge the first refspec fetched.
+	Defines, together with branch.<name>.remote, the upstream branch
+	for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
+	branch to merge and can also affect 'git push' (see push.default).
+	When in branch <name>, it tells 'git fetch' the default
+	refspec to be marked for merging in FETCH_HEAD. The value is
+	handled like the remote part of a refspec, and must match a
+	ref which is fetched from the remote given by
+	"branch.<name>.remote".
+	The merge information is used by 'git pull' (which at first calls
+	'git fetch') to lookup the default branch for merging. Without
+	this option, 'git pull' defaults to merge the first refspec fetched.
 	Specify multiple values to get an octopus merge.
+	If you wish to setup 'git pull' so that it merges into <name> from
+	another branch in the local repository, you can point
+	branch.<name>.merge to the desired branch, and use the relative path
+	setting `.` (a period) for branch.<name>.remote.
+
+branch.<name>.mergeOptions::
+	Sets default options for merging into branch <name>. The syntax and
+	supported options are the same as those of linkgit:git-merge[1], but
+	option values containing whitespace characters are currently not
+	supported.
+
+branch.<name>.rebase::
+	When true, rebase the branch <name> on top of the fetched branch,
+	instead of merging the default branch from the default remote when
+	"git pull" is run. See "pull.rebase" for doing this in a non
+	branch-specific manner.
++
+When preserve, also pass `--preserve-merges` along to 'git rebase'
+so that locally committed merge commits will not be flattened
+by running 'git pull'.
++
+*NOTE*: this is a possibly dangerous operation; do *not* use
+it unless you understand the implications (see linkgit:git-rebase[1]
+for details).
+
+branch.<name>.description::
+	Branch description, can be edited with
+	`git branch --edit-description`. Branch description is
+	automatically added in the format-patch cover letter or
+	request-pull summary.
+
+browser.<tool>.cmd::
+	Specify the command to invoke the specified browser. The
+	specified command is evaluated in shell with the URLs passed
+	as arguments. (See linkgit:git-web{litdd}browse[1].)
+
+browser.<tool>.path::
+	Override the path for the given tool that may be used to
+	browse HTML help (see '-w' option in linkgit:git-help[1]) or a
+	working repository in gitweb (see linkgit:git-instaweb[1]).
+
+clean.requireForce::
+	A boolean to make git-clean do nothing unless given -f,
+	-i or -n.   Defaults to true.
 
 color.branch::

+	If true, fetch will automatically behave as if the `--prune`
+	option was given on the command line.  See also `remote.<name>.prune`.
+
+format.attach::
+	Enable multipart/mixed attachments as the default for
+	'format-patch'.  The value can also be a double quoted string
+	which will enable attachments as the default and set the
+	value as the boundary.  See the --attach option in
+	linkgit:git-format-patch[1].
+
+format.numbered::
+	A boolean which can enable or disable sequence numbers in patch
+	subjects.  It defaults to "auto" which enables it only if there
+	is more than one patch.  It can be enabled or disabled for all
+	messages by setting it to "true" or "false".  See --numbered
+	option in linkgit:git-format-patch[1].

+	linkgit:git-format-patch[1].
+
+format.subjectPrefix::
+	The default for format-patch is to output files with the '[PATCH]'
+	subject prefix. Use this variable to change that prefix.
+
+format.signature::
+	The default for format-patch is to output a signature containing
+	the Git version number. Use this variable to change that default.
+	Set this variable to the empty string ("") to suppress
+	signature generation.
+
+format.signatureFile::
+	Works just like format.signature except the contents of the
+	file specified by this variable will be used as the signature.
 
 format.suffix::
 	The default for format-patch is to output files with the suffix
 	`.patch`. Use this variable to change that suffix (make sure to
 	include the dot if you want it).
 
-gc.packrefs::
-	`git gc` does not run `git pack-refs` in a bare repository by
-	default so that older dumb-transport clients can still fetch
-	from the repository.  Setting this to `true` lets `git
-	gc` to run `git pack-refs`.  Setting this to `false` tells
-	`git gc` never to run `git pack-refs`. The default setting is
-	`notbare`. Enable it only when you know you do not have to
-	support such clients.  The default setting will change to `true`
-	at some stage, and setting this to `false` will continue to
-	prevent `git pack-refs` from being run from `git gc`.
-
-gc.reflogexpire::
-	`git reflog expire` removes reflog entries older than
-	this time; defaults to 90 days.
-
-gc.reflogexpireunreachable::
-	`git reflog expire` removes reflog entries older than
+format.pretty::
+	The default pretty format for log/show/whatchanged command,
+	See linkgit:git-log[1], linkgit:git-show[1],
+	linkgit:git-whatchanged[1].
+
+format.thread::
+	The default threading style for 'git format-patch'.  Can be
+	a boolean value, or `shallow` or `deep`.  `shallow` threading
+	makes every mail a reply to the head of the series,
+	where the head is chosen from the cover letter, the
+	`--in-reply-to`, and the first patch mail, in this order.
+	`deep` threading makes every mail a reply to the previous one.
+	A true boolean value is the same as `shallow`, and a false
+	value disables threading.
+
+format.signOff::
+	A boolean value which lets you enable the `-s/--signoff` option of
+	format-patch by default. *Note:* Adding the Signed-off-by: line to a
+	patch should be a conscious act and means that you certify you have
+	the rights to submit this work under the same open source license.
+	Please see the 'SubmittingPatches' document for further discussion.
+
+format.coverLetter::
+	A boolean that controls whether to generate a cover-letter when
+	format-patch is invoked, but in addition can be set to "auto", to
+	generate a cover-letter only when there's more than one patch.
+
+filter.<driver>.clean::
+	The command which is used to convert the content of a worktree
+	file to a blob upon checkin.  See linkgit:gitattributes[5] for
+	details.
+
+filter.<driver>.smudge::
+	The command which is used to convert the content of a blob
+	object to a worktree file upon checkout.  See
+	linkgit:gitattributes[5] for details.
+
+fsck.<msg-id>::
+	Allows overriding the message type (error, warn or ignore) of a
+	specific message ID such as `missingEmail`.
++
+For convenience, fsck prefixes the error/warning with the message ID,
+e.g.  "missingEmail: invalid author/committer line - missing email" means
+that setting `fsck.missingEmail = ignore` will hide that issue.
++
+This feature is intended to support working with legacy repositories
+which cannot be repaired without disruptive changes.
+
+fsck.skipList::
+	The path to a sorted list of object names (i.e. one SHA-1 per
+	line) that are known to be broken in a non-fatal way and should
+	be ignored. This feature is useful when an established project
+	should be accepted despite early commits containing errors that
+	can be safely ignored such as invalid committer email addresses.
+	Note: corrupt objects cannot be skipped with this setting.
+
+gc.aggressiveDepth::
+	The depth parameter used in the delta compression
+	algorithm used by 'git gc --aggressive'.  This defaults
+	to 250.
+
+gc.aggressiveWindow::
+	The window size parameter used in the delta compression
+	algorithm used by 'git gc --aggressive'.  This defaults
+	to 250.
+
+gc.auto::
+	When there are approximately more than this many loose
+	objects in the repository, `git gc --auto` will pack them.
+	Some Porcelain commands use this command to perform a
+	light-weight garbage collection from time to time.  The
+	default value is 6700.  Setting this to 0 disables it.
+
+gc.autoPackLimit::
+	When there are more than this many packs that are not
+	marked with `*.keep` file in the repository, `git gc
+	--auto` consolidates them into one larger pack.  The
+	default	value is 50.  Setting this to 0 disables it.
+
+gc.autoDetach::
+	Make `git gc --auto` return immediately and run in background
+	if the system supports it. Default is true.
+
+gc.packRefs::
+	Running `git pack-refs` in a repository renders it
+	unclonable by Git versions prior to 1.5.1.2 over dumb
+	transports such as HTTP.  This variable determines whether
+	'git gc' runs `git pack-refs`. This can be set to `notbare`
+	to enable it within all non-bare repos or it can be set to a
+	boolean value.  The default is `true`.
+
+gc.pruneExpire::
+	When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
+	Override the grace period with this config variable.  The value
+	"now" may be used to disable this grace period and always prune
+	unreachable objects immediately, or "never" may be used to
+	suppress pruning.
+
+gc.worktreePruneExpire::
+	When 'git gc' is run, it calls
+	'git worktree prune --expire 3.months.ago'.
+	This config variable can be used to set a different grace
+	period. The value "now" may be used to disable the grace
+	period and prune $GIT_DIR/worktrees immediately, or "never"
+	may be used to suppress pruning.
+
+gc.reflogExpire::
+gc.<pattern>.reflogExpire::
+	'git reflog expire' removes reflog entries older than
+	this time; defaults to 90 days. The value "now" expires all
+	entries immediately, and "never" suppresses expiration
+	altogether. With "<pattern>" (e.g.
+	"refs/stash") in the middle the setting applies only to
+	the refs that match the <pattern>.
+
+gc.reflogExpireUnreachable::
+gc.<pattern>.reflogExpireUnreachable::
+	'git reflog expire' removes reflog entries older than

+
+gitcvs.commitMsgAnnotation::
+	Append this string to each commit message. Set to empty string
+	to disable this feature. Defaults to "via git-CVS emulator".
 
 gitcvs.enabled::
-	Whether the cvs pserver interface is enabled for this repository.
-	See gitlink:git-cvsserver[1].
+	Whether the CVS server interface is enabled for this repository.
+	See linkgit:git-cvsserver[1].
+
+gitcvs.logFile::
+	Path to a log file where the CVS server interface well... logs
+	various stuff. See linkgit:git-cvsserver[1].
+
+gitcvs.usecrlfattr::
+	If true, the server will look up the end-of-line conversion
+	attributes for files to determine the '-k' modes to use. If
+	the attributes force Git to treat a file as text,
+	the '-k' mode will be left blank so CVS clients will
+	treat it as text. If they suppress text conversion, the file
+	will be set with '-kb' mode, which suppresses any newline munging
+	the client might otherwise do. If the attributes do not allow
+	the file type to be determined, then 'gitcvs.allBinary' is
+	used. See linkgit:gitattributes[5].
+
+gitcvs.allBinary::
+	This is used if 'gitcvs.usecrlfattr' does not resolve
+	the correct '-kb' mode to use. If true, all
+	unresolved files are sent to the client in
+	mode '-kb'. This causes the client to treat them
+	as binary files, which suppresses any newline munging it
+	otherwise might do. Alternatively, if it is set to "guess",
+	then the contents of the file are examined to decide if
+	it is binary, similar to 'core.autocrlf'.
+
+gitcvs.dbName::
+	Database used by git-cvsserver to cache revision information
+	derived from the Git repository. The exact meaning depends on the
+	used database driver, for SQLite (which is the default driver) this
+	is a filename. Supports variable substitution (see
+	linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
+	Default: '%Ggitcvs.%m.sqlite'
+
+gitcvs.dbDriver::
+	Used Perl DBI driver. You can specify any available driver
+	for this here, but it might not work. git-cvsserver is tested
+	with 'DBD::SQLite', reported to work with 'DBD::Pg', and
+	reported *not* to work with 'DBD::mysql'. Experimental feature.
+	May not contain double colons (`:`). Default: 'SQLite'.
+	See linkgit:git-cvsserver[1].
+
+gitcvs.dbUser, gitcvs.dbPass::
+	Database user and password. Only useful if setting 'gitcvs.dbDriver',
+	since SQLite has no concept of database users and/or passwords.
+	'gitcvs.dbUser' supports variable substitution (see
+	linkgit:git-cvsserver[1] for details).
+
+gitcvs.dbTableNamePrefix::
+	Database table name prefix.  Prepended to the names of any
+	database tables used, allowing a single database to be used
+	for several repositories.  Supports variable substitution (see
+	linkgit:git-cvsserver[1] for details).  Any non-alphabetic
+	characters will be replaced with underscores.
+
+All gitcvs variables except for 'gitcvs.usecrlfattr' and
+'gitcvs.allBinary' can also be specified as
+'gitcvs.<access_method>.<varname>' (where 'access_method'
+is one of "ext" and "pserver") to make them apply only for the given
+access method.

+grep.lineNumber::
+	If set to true, enable '-n' option by default.
+
+grep.patternType::
+	Set the default matching behavior. Using a value of 'basic', 'extended',
+	'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
+	'--fixed-strings', or '--perl-regexp' option accordingly, while the
+	value 'default' will return to the default matching behavior.
+
+grep.extendedRegexp::
+	If set to true, enable '--extended-regexp' option by default. This
+	option is ignored when the 'grep.patternType' option is set to a value
+	other than 'default'.
+
+gpg.program::
+	Use this custom program instead of "gpg" found on $PATH when
+	making or verifying a PGP signature. The program must support the
+	same command-line interface as GPG, namely, to verify a detached
+	signature, "gpg --verify $file - <$signature" is run, and the
+	program is expected to signal a good signature by exiting with
+	code 0, and to generate an ASCII-armored detached signature, the
+	standard input of "gpg -bsau $key" is fed with the contents to be
+	signed, and the program is expected to send the result to its
+	standard output.
+
+gui.commitMsgWidth::
+	Defines how wide the commit message window is in the
+	linkgit:git-gui[1]. "75" is the default.
+
+gui.diffContext::
+	Specifies how many context lines should be used in calls to diff
+	made by the linkgit:git-gui[1]. The default is "5".
+
+gui.displayUntracked::
+	Determines if linkgit::git-gui[1] shows untracked files
+	in the file list. The default is "true".
+
+gui.encoding::
+	Specifies the default encoding to use for displaying of
+	file contents in linkgit:git-gui[1] and linkgit:gitk[1].
+	It can be overridden by setting the 'encoding' attribute
+	for relevant files (see linkgit:gitattributes[5]).
+	If this option is not set, the tools default to the
+	locale encoding.
+
+gui.matchTrackingBranch::
+	Determines if new branches created with linkgit:git-gui[1] should
+	default to tracking remote branches with matching names or
+	not. Default: "false".
+
+gui.newBranchTemplate::
+	Is used as suggested name when creating new branches using the
+	linkgit:git-gui[1].
+
+gui.pruneDuringFetch::
+	"true" if linkgit:git-gui[1] should prune remote-tracking branches when
+	performing a fetch. The default value is "false".
+
+gui.trustmtime::
+	Determines if linkgit:git-gui[1] should trust the file modification
+	timestamp or not. By default the timestamps are not trusted.
+
+gui.spellingDictionary::
+	Specifies the dictionary used for spell checking commit messages in
+	the linkgit:git-gui[1]. When set to "none" spell checking is turned
+	off.
+
+gui.fastCopyBlame::
+	If true, 'git gui blame' uses `-C` instead of `-C -C` for original
+	location detection. It makes blame significantly faster on huge
+	repositories at the expense of less thorough copy detection.
+
+gui.copyBlameThreshold::
+	Specifies the threshold to use in 'git gui blame' original location
+	detection, measured in alphanumeric characters. See the
+	linkgit:git-blame[1] manual for more information on copy detection.
+
+gui.blamehistoryctx::
+	Specifies the radius of history context in days to show in
+	linkgit:gitk[1] for the selected commit, when the `Show History
+	Context` menu item is invoked from 'git gui blame'. If this
+	variable is set to zero, the whole history is shown.
+
+guitool.<name>.cmd::
+	Specifies the shell command line to execute when the corresponding item
+	of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
+	mandatory for every tool. The command is executed from the root of
+	the working directory, and in the environment it receives the name of
+	the tool as 'GIT_GUITOOL', the name of the currently selected file as
+	'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
+	the head is detached, 'CUR_BRANCH' is empty).
+
+guitool.<name>.needsFile::
+	Run the tool only if a diff is selected in the GUI. It guarantees
+	that 'FILENAME' is not empty.
+
+guitool.<name>.noConsole::
+	Run the command silently, without creating a window to display its
+	output.
+
+guitool.<name>.noRescan::
+	Don't rescan the working directory for changes after the tool
+	finishes execution.
+
+guitool.<name>.confirm::
+	Show a confirmation dialog before actually running the tool.
+
+guitool.<name>.argPrompt::
+	Request a string argument from the user, and pass it to the tool
+	through the 'ARGS' environment variable. Since requesting an
+	argument implies confirmation, the 'confirm' option has no effect
+	if this is enabled. If the option is set to 'true', 'yes', or '1',
+	the dialog uses a built-in generic prompt; otherwise the exact
+	value of the variable is used.
+
+guitool.<name>.revPrompt::
+	Request a single valid revision from the user, and set the
+	'REVISION' environment variable. In other aspects this option
+	is similar to 'argPrompt', and can be used together with it.
+
+guitool.<name>.revUnmerged::
+	Show only unmerged branches in the 'revPrompt' subdialog.
+	This is useful for tools similar to merge or rebase, but not
+	for things like checkout or reset.
+
+guitool.<name>.title::
+	Specifies the title to use for the prompt dialog. The default
+	is the tool name.
+
+guitool.<name>.prompt::
+	Specifies the general prompt string to display at the top of
+	the dialog, before subsections for 'argPrompt' and 'revPrompt'.
+	The default value includes the actual command.
+
+help.browser::
+	Specify the browser that will be used to display help in the
+	'web' format. See linkgit:git-help[1].
+
+help.format::
+	Override the default help format used by linkgit:git-help[1].
+	Values 'man', 'info', 'web' and 'html' are supported. 'man' is
+	the default. 'web' and 'html' are the same.
+
+help.autoCorrect::
+	Automatically correct and execute mistyped commands after
+	waiting for the given number of deciseconds (0.1 sec). If more
+	than one command can be deduced from the entered text, nothing
+	will be executed.  If the value of this option is negative,
+	the corrected command will be executed immediately. If the
+	value is 0 - the command will be just shown but not executed.
+	This is the default.
+
+help.htmlPath::
+	Specify the path where the HTML documentation resides. File system paths
+	and URLs are supported. HTML pages will be prefixed with this path when
+	help is displayed in the 'web' format. This defaults to the documentation
+	path of your Git installation.
+
+http.proxy::
+	Override the HTTP proxy, normally configured using the 'http_proxy',
+	'https_proxy', and 'all_proxy' environment variables (see
+	`curl(1)`).  This can be overridden on a per-remote basis; see
+	remote.<name>.proxy
+
+http.cookieFile::
+	File containing previously stored cookie lines which should be used
+	in the Git http session, if they match the server. The file format
+	of the file to read cookies from should be plain HTTP headers or
+	the Netscape/Mozilla cookie file format (see linkgit:curl[1]).
+	NOTE that the file specified with http.cookieFile is only used as
+	input unless http.saveCookies is set.
+
+http.saveCookies::
+	If set, store cookies received during requests to the file specified by
+	http.cookieFile. Has no effect if http.cookieFile is unset.
+
+http.sslVersion::
+	The SSL version to use when negotiating an SSL connection, if you
+	want to force the default.  The available and default version
+	depend on whether libcurl was built against NSS or OpenSSL and the
+	particular configuration of the crypto library in use. Internally
+	this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
+	documentation for more details on the format of this option and
+	for the ssl version supported. Actually the possible values of
+	this option are:
+
+	- sslv2
+	- sslv3
+	- tlsv1
+	- tlsv1.0
+	- tlsv1.1
+	- tlsv1.2

+
+http.<url>.*::
+	Any of the http.* options above can be applied selectively to some URLs.
+	For a config key to match a URL, each element of the config key is
+	compared to that of the URL, in the following order:
++
+--
+. Scheme (e.g., `https` in `https://example.com/`). This field
+  must match exactly between the config key and the URL.
+
+. Host/domain name (e.g., `example.com` in `https://example.com/`).
+  This field must match exactly between the config key and the URL.
+
+. Port number (e.g., `8080` in `http://example.com:8080/`).
+  This field must match exactly between the config key and the URL.
+  Omitted port numbers are automatically converted to the correct
+  default for the scheme before matching.
+
+. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
+  path field of the config key must match the path field of the URL
+  either exactly or as a prefix of slash-delimited path elements.  This means
+  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
+  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
+  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
+  key with just path `foo/`).
+
+. User name (e.g., `user` in `https://user@example.com/repo.git`). If
+  the config key has a user name it must match the user name in the
+  URL exactly. If the config key does not have a user name, that
+  config key will match a URL with any user name (including none),
+  but at a lower precedence than a config key with a user name.
+--
++
+The list above is ordered by decreasing precedence; a URL that matches
+a config key's path is preferred to one that matches its user name. For example,
+if the URL is `https://user@example.com/foo/bar` a config key match of
+`https://example.com/foo` will be preferred over a config key match of
+`https://user@example.com`.
++
+All URLs are normalized before attempting any matching (the password part,
+if embedded in the URL, is always ignored for matching purposes) so that

+	is Apache.
+
+instaweb.port::
+	The port number to bind the gitweb httpd to. See
+	linkgit:git-instaweb[1].
+
+interactive.singleKey::
+	In interactive commands, allow the user to provide one-letter
+	input with a single key (i.e., without hitting enter).
+	Currently this is used by the `--patch` mode of
+	linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
+	linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
+	setting is silently ignored if portable keystroke input
+	is not available; requires the Perl module Term::ReadKey.
+
+log.abbrevCommit::
+	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
+	linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
+	override this option with `--no-abbrev-commit`.
+
+log.date::
+	Set the default date-time mode for the 'log' command.
+	Setting a value for log.date is similar to using 'git log''s
+	`--date` option.  Possible values are `relative`, `local`,
+	`default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
+	for details.
+
+log.decorate::
+	Print out the ref names of any commits that are shown by the log
+	command. If 'short' is specified, the ref name prefixes 'refs/heads/',
+	'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
+	specified, the full ref name (including prefix) will be printed.
+	This is the same as the log commands '--decorate' option.
+
+log.showRoot::
 	If true, the initial commit will be shown as a big creation event.
 	This is equivalent to a diff against an empty tree.

-merge.summary::
-	Whether to include summaries of merged commits in newly created
-	merge commit messages. False by default.
-
-merge.verbosity::
-	Controls the amount of output shown by the recursive merge
-	strategy.  Level 0 outputs nothing except a final error
-	message if conflicts were detected. Level 1 outputs only
-	conflicts, 2 outputs conflicts and file changes.  Level 5 and
-	above outputs debugging information.  The default is level 2.
+log.mailmap::
+	If true, makes linkgit:git-log[1], linkgit:git-show[1], and
+	linkgit:git-whatchanged[1] assume `--use-mailmap`.
+
+mailinfo.scissors::
+	If true, makes linkgit:git-mailinfo[1] (and therefore
+	linkgit:git-am[1]) act by default as if the --scissors option
+	was provided on the command-line. When active, this features
+	removes everything from the message body before a scissors
+	line (i.e. consisting mainly of ">8", "8<" and "-").
+
+mailmap.file::
+	The location of an augmenting mailmap file. The default
+	mailmap, located in the root of the repository, is loaded
+	first, then the mailmap file pointed to by this variable.
+	The location of the mailmap file may be in a repository
+	subdirectory, or somewhere outside of the repository itself.
+	See linkgit:git-shortlog[1] and linkgit:git-blame[1].
+
+mailmap.blob::
+	Like `mailmap.file`, but consider the value as a reference to a
+	blob in the repository. If both `mailmap.file` and
+	`mailmap.blob` are given, both are parsed, with entries from
+	`mailmap.file` taking precedence. In a bare repository, this
+	defaults to `HEAD:.mailmap`. In a non-bare repository, it
+	defaults to empty.
+
+man.viewer::
+	Specify the programs that may be used to display help in the
+	'man' format. See linkgit:git-help[1].
+
+man.<tool>.cmd::
+	Specify the command to invoke the specified man viewer. The
+	specified command is evaluated in shell with the man page
+	passed as argument. (See linkgit:git-help[1].)
+
+man.<tool>.path::
+	Override the path for the given tool that may be used to
+	display help in the 'man' format. See linkgit:git-help[1].
+
+include::merge-config.txt[]
+
+mergetool.<tool>.path::
+	Override the path for the given tool.  This is useful in case
+	your tool is not in the PATH.
+
+mergetool.<tool>.cmd::
+	Specify the command to invoke the specified merge tool.  The
+	specified command is evaluated in shell with the following
+	variables available: 'BASE' is the name of a temporary file
+	containing the common base of the files to be merged, if available;
+	'LOCAL' is the name of a temporary file containing the contents of
+	the file on the current branch; 'REMOTE' is the name of a temporary
+	file containing the contents of the file from the branch being
+	merged; 'MERGED' contains the name of the file to which the merge
+	tool should write the results of a successful merge.
+
+mergetool.<tool>.trustExitCode::
+	For a custom merge command, specify whether the exit code of
+	the merge command can be used to determine whether the merge was
+	successful.  If this is not set to true then the merge target file
+	timestamp is checked and the merge assumed to have been successful
+	if the file has been updated, otherwise the user is prompted to
+	indicate the success of the merge.
+
+mergetool.meld.hasOutput::
+	Older versions of `meld` do not support the `--output` option.
+	Git will attempt to detect whether `meld` supports `--output`
+	by inspecting the output of `meld --help`.  Configuring
+	`mergetool.meld.hasOutput` will make Git skip these checks and
+	use the configured value instead.  Setting `mergetool.meld.hasOutput`
+	to `true` tells Git to unconditionally use the `--output` option,
+	and `false` avoids using `--output`.
+
+mergetool.keepBackup::
+	After performing a merge, the original file with conflict markers
+	can be saved as a file with a `.orig` extension.  If this variable
+	is set to `false` then this file is not preserved.  Defaults to
+	`true` (i.e. keep the backup files).
+
+mergetool.keepTemporaries::
+	When invoking a custom merge tool, Git uses a set of temporary
+	files to pass to the tool. If the tool returns an error and this
+	variable is set to `true`, then these temporary files will be
+	preserved, otherwise they will be removed after the tool has
+	exited. Defaults to `false`.
+
+mergetool.writeToTemp::
+	Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
+	conflicting files in the worktree by default.  Git will attempt
+	to use a temporary directory for these files when set `true`.
+	Defaults to `false`.
+
+mergetool.prompt::
+	Prompt before each invocation of the merge resolution program.
+
+notes.mergeStrategy::
+	Which merge strategy to choose by default when resolving notes
+	conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
+	`cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
+	section of linkgit:git-notes[1] for more information on each strategy.
+
+notes.<name>.mergeStrategy::
+	Which merge strategy to choose when doing a notes merge into
+	refs/notes/<name>.  This overrides the more general
+	"notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
+	linkgit:git-notes[1] for more information on the available strategies.
+
+notes.displayRef::
+	The (fully qualified) refname from which to show notes when
+	showing commit messages.  The value of this variable can be set
+	to a glob, in which case notes from all matching refs will be
+	shown.  You may also specify this configuration variable
+	several times.  A warning will be issued for refs that do not
+	exist, but a glob that does not match any refs is silently
+	ignored.
++
+This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
+environment variable, which must be a colon separated list of refs or
+globs.
++
+The effective value of "core.notesRef" (possibly overridden by
+GIT_NOTES_REF) is also implicitly added to the list of refs to be
+displayed.
+
+notes.rewrite.<command>::
+	When rewriting commits with <command> (currently `amend` or
+	`rebase`) and this variable is set to `true`, Git
+	automatically copies your notes from the original to the
+	rewritten commit.  Defaults to `true`, but see
+	"notes.rewriteRef" below.
+
+notes.rewriteMode::
+	When copying notes during a rewrite (see the
+	"notes.rewrite.<command>" option), determines what to do if
+	the target commit already has a note.  Must be one of
+	`overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
+	Defaults to `concatenate`.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
+environment variable.
+
+notes.rewriteRef::
+	When copying notes during a rewrite, specifies the (fully
+	qualified) ref whose notes should be copied.  The ref may be a
+	glob, in which case notes in all matching refs will be copied.
+	You may also specify this configuration several times.
++
+Does not have a default value; you must configure this variable to
+enable note rewriting.  Set it to `refs/notes/commits` to enable
+rewriting for the default commit notes.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
+environment variable, which must be a colon separated list of refs or
+globs.
 
 pack.window::
-	The size of the window used by gitlink:git-pack-objects[1] when no
+	The size of the window used by linkgit:git-pack-objects[1] when no
 	window size is given on the command line. Defaults to 10.
 
+pack.depth::
+	The maximum delta depth used by linkgit:git-pack-objects[1] when no
+	maximum depth is given on the command line. Defaults to 50.
+
+pack.windowMemory::
+	The maximum size of memory that is consumed by each thread
+	in linkgit:git-pack-objects[1] for pack window memory when
+	no limit is given on the command line.  The value can be
+	suffixed with "k", "m", or "g".  When left unconfigured (or
+	set explicitly to 0), there will be no limit.
+
+pack.compression::
+	An integer -1..9, indicating the compression level for objects
+	in a pack file. -1 is the zlib default. 0 means no
+	compression, and 1..9 are various speed/size tradeoffs, 9 being
+	slowest.  If not set,  defaults to core.compression.  If that is
+	not set,  defaults to -1, the zlib default, which is "a default
+	compromise between speed and compression (currently equivalent
+	to level 6)."
++
+Note that changing the compression level will not automatically recompress
+all existing objects. You can force recompression by passing the -F option
+to linkgit:git-repack[1].
+
+pack.deltaCacheSize::
+	The maximum memory in bytes used for caching deltas in
+	linkgit:git-pack-objects[1] before writing them out to a pack.
+	This cache is used to speed up the writing object phase by not
+	having to recompute the final delta result once the best match
+	for all objects is found.  Repacking large repositories on machines
+	which are tight with memory might be badly impacted by this though,
+	especially if this cache pushes the system into swapping.
+	A value of 0 means no limit. The smallest size of 1 byte may be
+	used to virtually disable this cache. Defaults to 256 MiB.
+
+pack.deltaCacheLimit::
+	The maximum size of a delta, that is cached in
+	linkgit:git-pack-objects[1]. This cache is used to speed up the
+	writing object phase by not having to recompute the final delta
+	result once the best match for all objects is found. Defaults to 1000.
+
+pack.threads::
+	Specifies the number of threads to spawn when searching for best
+	delta matches.  This requires that linkgit:git-pack-objects[1]
+	be compiled with pthreads otherwise this option is ignored with a
+	warning. This is meant to reduce packing time on multiprocessor
+	machines. The required amount of memory for the delta search window
+	is however multiplied by the number of threads.
+	Specifying 0 will cause Git to auto-detect the number of CPU's
+	and set the number of threads accordingly.
+
+pack.indexVersion::
+	Specify the default pack index version.  Valid values are 1 for
+	legacy pack index used by Git versions prior to 1.5.2, and 2 for
+	the new pack index with capabilities for packs larger than 4 GB
+	as well as proper protection against the repacking of corrupted
+	packs.  Version 2 is the default.  Note that version 2 is enforced
+	and this config option ignored whenever the corresponding pack is
+	larger than 2 GB.
++
+If you have an old Git that does not understand the version 2 `*.idx` file,
+cloning or fetching over a non native protocol (e.g. "http" and "rsync")
+that will copy both `*.pack` file and corresponding `*.idx` file from the
+other side may give you a repository that cannot be accessed with your
+older version of Git. If the `*.pack` file is smaller than 2 GB, however,
+you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
+the `*.idx` file.
+
+pack.packSizeLimit::
+	The maximum size of a pack.  This setting only affects
+	packing to a file when repacking, i.e. the git:// protocol
+	is unaffected.  It can be overridden by the `--max-pack-size`
+	option of linkgit:git-repack[1]. The minimum size allowed is
+	limited to 1 MiB. The default is unlimited.
+	Common unit suffixes of 'k', 'm', or 'g' are
+	supported.
+
+pack.useBitmaps::
+	When true, git will use pack bitmaps (if available) when packing
+	to stdout (e.g., during the server side of a fetch). Defaults to
+	true. You should not generally need to turn this off unless
+	you are debugging pack bitmaps.
+
+pack.writeBitmaps (deprecated)::
+	This is a deprecated synonym for `repack.writeBitmaps`.
+
+pack.writeBitmapHashCache::
+	When true, git will include a "hash cache" section in the bitmap
+	index (if one is written). This cache can be used to feed git's
+	delta heuristics, potentially leading to better deltas between
+	bitmapped and non-bitmapped objects (e.g., when serving a fetch
+	between an older, bitmapped pack and objects that have been
+	pushed since the last gc). The downside is that it consumes 4
+	bytes per object of disk space, and that JGit's bitmap
+	implementation does not understand it, causing it to complain if
+	Git and JGit are used on the same repository. Defaults to false.
+
+pager.<cmd>::
+	If the value is boolean, turns on or off pagination of the
+	output of a particular Git subcommand when writing to a tty.
+	Otherwise, turns on pagination for the subcommand using the
+	pager specified by the value of `pager.<cmd>`.  If `--paginate`
+	or `--no-pager` is specified on the command line, it takes
+	precedence over this option.  To disable pagination for all
+	commands, set `core.pager` or `GIT_PAGER` to `cat`.
+
+pretty.<name>::
+	Alias for a --pretty= format string, as specified in
+	linkgit:git-log[1]. Any aliases defined here can be used just
+	as the built-in pretty formats could. For example,
+	running `git config pretty.changelog "format:* %H %s"`
+	would cause the invocation `git log --pretty=changelog`
+	to be equivalent to running `git log "--pretty=format:* %H %s"`.
+	Note that an alias with the same name as a built-in format
+	will be silently ignored.
+
+pull.ff::
+	By default, Git does not create an extra merge commit when merging
+	a commit that is a descendant of the current commit. Instead, the
+	tip of the current branch is fast-forwarded. When set to `false`,
+	this variable tells Git to create an extra merge commit in such
+	a case (equivalent to giving the `--no-ff` option from the command
+	line). When set to `only`, only such fast-forward merges are
+	allowed (equivalent to giving the `--ff-only` option from the
+	command line). This setting overrides `merge.ff` when pulling.
+
+pull.rebase::
+	When true, rebase branches on top of the fetched branch, instead
+	of merging the default branch from the default remote when "git
+	pull" is run. See "branch.<name>.rebase" for setting this on a
+	per-branch basis.
++
+When preserve, also pass `--preserve-merges` along to 'git rebase'
+so that locally committed merge commits will not be flattened
+by running 'git pull'.
++
+*NOTE*: this is a possibly dangerous operation; do *not* use
+it unless you understand the implications (see linkgit:git-rebase[1]
+for details).

+push.default::
+	Defines the action `git push` should take if no refspec is
+	explicitly given.  Different values are well-suited for
+	specific workflows; for instance, in a purely central workflow
+	(i.e. the fetch source is equal to the push destination),
+	`upstream` is probably what you want.  Possible values are:
++
+--
+
+* `nothing` - do not push anything (error out) unless a refspec is
+  explicitly given. This is primarily meant for people who want to
+  avoid mistakes by always being explicit.
+
+* `current` - push the current branch to update a branch with the same
+  name on the receiving end.  Works in both central and non-central
+  workflows.
+
+* `upstream` - push the current branch back to the branch whose
+  changes are usually integrated into the current branch (which is
+  called `@{upstream}`).  This mode only makes sense if you are
+  pushing to the same repository you would normally pull from
+  (i.e. central workflow).
+
+* `simple` - in centralized workflow, work like `upstream` with an
+  added safety to refuse to push if the upstream branch's name is
+  different from the local one.
++
+When pushing to a remote that is different from the remote you normally
+pull from, work as `current`.  This is the safest option and is suited
+for beginners.
++
+This mode has become the default in Git 2.0.
+
+* `matching` - push all branches having the same name on both ends.
+  This makes the repository you are pushing to remember the set of
+  branches that will be pushed out (e.g. if you always push 'maint'
+  and 'master' there and no other branches, the repository you push
+  to will have these two branches, and your local 'maint' and
+  'master' will be pushed there).
++
+To use this mode effectively, you have to make sure _all_ the
+branches you would push out are ready to be pushed out before
+running 'git push', as the whole point of this mode is to allow you
+to push all of the branches in one go.  If you usually finish work
+on only one branch and push out the result, while other branches are
+unfinished, this mode is not for you.  Also this mode is not
+suitable for pushing into a shared central repository, as other
+people may add new branches there, or update the tip of existing
+branches outside your control.
++
+This used to be the default, but not since Git 2.0 (`simple` is the
+new default).
+
+--
+
+push.followTags::
+	If set to true enable '--follow-tags' option by default.  You
+	may override this configuration at time of push by specifying
+	'--no-follow-tags'.
+
+push.gpgSign::
+	May be set to a boolean value, or the string 'if-asked'. A true
+	value causes all pushes to be GPG signed, as if '--signed' is
+	passed to linkgit:git-push[1]. The string 'if-asked' causes
+	pushes to be signed if the server supports it, as if
+	'--signed=if-asked' is passed to 'git push'. A false value may
+	override a value from a lower-priority config file. An explicit
+	command-line flag always overrides this config option.
+
+rebase.stat::
+	Whether to show a diffstat of what changed upstream since the last
+	rebase. False by default.
+
+rebase.autoSquash::
+	If set to true enable '--autosquash' option by default.
+
+rebase.autoStash::
+	When set to true, automatically create a temporary stash
+	before the operation begins, and apply it after the operation
+	ends.  This means that you can run rebase on a dirty worktree.
+	However, use with care: the final stash application after a
+	successful rebase might result in non-trivial conflicts.
+	Defaults to false.
+
+rebase.missingCommitsCheck::
+	If set to "warn", git rebase -i will print a warning if some
+	commits are removed (e.g. a line was deleted), however the
+	rebase will still proceed. If set to "error", it will print
+	the previous warning and stop the rebase, 'git rebase
+	--edit-todo' can then be used to correct the error. If set to
+	"ignore", no checking is done.
+	To drop a commit without warning or error, use the `drop`
+	command in the todo-list.
+	Defaults to "ignore".
+
+rebase.instructionFormat
+	A format string, as specified in linkgit:git-log[1], to be used for
+	the instruction list during an interactive rebase.  The format will automatically
+	have the long commit hash prepended to the format.
+
+receive.advertiseAtomic::
+	By default, git-receive-pack will advertise the atomic push
+	capability to its clients. If you don't want to this capability
+	to be advertised, set this variable to false.
+
+receive.autogc::
+	By default, git-receive-pack will run "git-gc --auto" after
+	receiving data from git-push and updating refs.  You can stop
+	it by setting this variable to false.
+
+receive.certNonceSeed::
+	By setting this variable to a string, `git receive-pack`
+	will accept a `git push --signed` and verifies it by using
+	a "nonce" protected by HMAC using this string as a secret
+	key.
+
+receive.certNonceSlop::
+	When a `git push --signed` sent a push certificate with a
+	"nonce" that was issued by a receive-pack serving the same
+	repository within this many seconds, export the "nonce"
+	found in the certificate to `GIT_PUSH_CERT_NONCE` to the
+	hooks (instead of what the receive-pack asked the sending
+	side to include).  This may allow writing checks in
+	`pre-receive` and `post-receive` a bit easier.  Instead of
+	checking `GIT_PUSH_CERT_NONCE_SLOP` environment variable
+	that records by how many seconds the nonce is stale to
+	decide if they want to accept the certificate, they only
+	can check `GIT_PUSH_CERT_NONCE_STATUS` is `OK`.
+
+receive.fsckObjects::
+	If it is set to true, git-receive-pack will check all received
+	objects. It will abort in the case of a malformed object or a
+	broken link. The result of an abort are only dangling objects.
+	Defaults to false. If not set, the value of `transfer.fsckObjects`
+	is used instead.
+
+receive.fsck.<msg-id>::
+	When `receive.fsckObjects` is set to true, errors can be switched
+	to warnings and vice versa by configuring the `receive.fsck.<msg-id>`
+	setting where the `<msg-id>` is the fsck message ID and the value
+	is one of `error`, `warn` or `ignore`. For convenience, fsck prefixes
+	the error/warning with the message ID, e.g. "missingEmail: invalid
+	author/committer line - missing email" means that setting
+	`receive.fsck.missingEmail = ignore` will hide that issue.
++
+This feature is intended to support working with legacy repositories
+which would not pass pushing when `receive.fsckObjects = true`, allowing
+the host to accept repositories with certain known issues but still catch
+other issues.
+
+receive.fsck.skipList::
+	The path to a sorted list of object names (i.e. one SHA-1 per
+	line) that are known to be broken in a non-fatal way and should
+	be ignored. This feature is useful when an established project
+	should be accepted despite early commits containing errors that
+	can be safely ignored such as invalid committer email addresses.
+	Note: corrupt objects cannot be skipped with this setting.
+
+receive.unpackLimit::
+	If the number of objects received in a push is below this
+	limit then the objects will be unpacked into loose object
+	files. However if the number of received objects equals or
+	exceeds this limit then the received pack will be stored as
+	a pack, after adding any missing delta bases.  Storing the
+	pack from a push can make the push operation complete faster,
+	especially on slow filesystems.  If not set, the value of
+	`transfer.unpackLimit` is used instead.
+
+receive.denyDeletes::
+	If set to true, git-receive-pack will deny a ref update that deletes
+	the ref. Use this to prevent such a ref deletion via a push.
+
+receive.denyDeleteCurrent::
+	If set to true, git-receive-pack will deny a ref update that
+	deletes the currently checked out branch of a non-bare repository.
+
+receive.denyCurrentBranch::
+	If set to true or "refuse", git-receive-pack will deny a ref update
+	to the currently checked out branch of a non-bare repository.
+	Such a push is potentially dangerous because it brings the HEAD
+	out of sync with the index and working tree. If set to "warn",
+	print a warning of such a push to stderr, but allow the push to
+	proceed. If set to false or "ignore", allow such pushes with no
+	message. Defaults to "refuse".
++
+Another option is "updateInstead" which will update the working
+tree if pushing into the current branch.  This option is
+intended for synchronizing working directories when one side is not easily
+accessible via interactive ssh (e.g. a live web site, hence the requirement
+that the working directory be clean). This mode also comes in handy when
+developing inside a VM to test and fix code on different Operating Systems.
++
+By default, "updateInstead" will refuse the push if the working tree or
+the index have any difference from the HEAD, but the `push-to-checkout`
+hook can be used to customize this.  See linkgit:githooks[5].
+
+receive.denyNonFastForwards::
+	If set to true, git-receive-pack will deny a ref update which is
+	not a fast-forward. Use this to prevent such an update via a push,
+	even if that push is forced. This configuration variable is
+	set when initializing a shared repository.
+
+receive.hideRefs::
+	This variable is the same as `transfer.hideRefs`, but applies
+	only to `receive-pack` (and so affects pushes, but not fetches).
+	An attempt to update or delete a hidden ref by `git push` is
+	rejected.
+
+receive.updateServerInfo::
+	If set to true, git-receive-pack will run git-update-server-info
+	after receiving data from git-push and updating refs.
+
+receive.shallowUpdate::
+	If set to true, .git/shallow can be updated when new refs
+	require new shallow roots. Otherwise those refs are rejected.
+
+remote.pushDefault::
+	The remote to push to by default.  Overrides
+	`branch.<name>.remote` for all branches, and is overridden by
+	`branch.<name>.pushRemote` for specific branches.
+
 remote.<name>.url::
-	The URL of a remote repository.  See gitlink:git-fetch[1] or
-	gitlink:git-push[1].
+	The URL of a remote repository.  See linkgit:git-fetch[1] or
+	linkgit:git-push[1].
+
+remote.<name>.pushurl::
+	The push URL of a remote repository.  See linkgit:git-push[1].
+
+remote.<name>.proxy::
+	For remotes that require curl (http, https and ftp), the URL to
+	the proxy to use for that remote.  Set to the empty string to
+	disable proxying for that remote.
 
 remote.<name>.fetch::
-	The default set of "refspec" for gitlink:git-fetch[1]. See
-	gitlink:git-fetch[1].
+	The default set of "refspec" for linkgit:git-fetch[1]. See
+	linkgit:git-fetch[1].
 
 remote.<name>.push::
-	The default set of "refspec" for gitlink:git-push[1]. See
-	gitlink:git-push[1].
+	The default set of "refspec" for linkgit:git-push[1]. See
+	linkgit:git-push[1].
+
+remote.<name>.mirror::
+	If true, pushing to this remote will automatically behave
+	as if the `--mirror` option was given on the command line.
 
 remote.<name>.skipDefaultUpdate::
 	If true, this remote will be skipped by default when updating
-	using the remote subcommand of gitlink:git-remote[1].
+	using linkgit:git-fetch[1] or the `update` subcommand of
+	linkgit:git-remote[1].
+
+remote.<name>.skipFetchAll::
+	If true, this remote will be skipped by default when updating
+	using linkgit:git-fetch[1] or the `update` subcommand of
+	linkgit:git-remote[1].
 
 remote.<name>.receivepack::
 	The default program to execute on the remote side when pushing.  See
-	option \--exec of gitlink:git-push[1].
+	option --receive-pack of linkgit:git-push[1].
 
 remote.<name>.uploadpack::
 	The default program to execute on the remote side when fetching.  See
-	option \--exec of gitlink:git-fetch-pack[1].
-
-remote.<name>.tagopt::
-	Setting this value to --no-tags disables automatic tag following when fetching
-	from remote <name>
+	option --upload-pack of linkgit:git-fetch-pack[1].
+
+remote.<name>.tagOpt::
+	Setting this value to --no-tags disables automatic tag following when
+	fetching from remote <name>. Setting it to --tags will fetch every
+	tag from remote <name>, even if they are not reachable from remote
+	branch heads. Passing these flags directly to linkgit:git-fetch[1] can
+	override this setting. See options --tags and --no-tags of
+	linkgit:git-fetch[1].
+
+remote.<name>.vcs::
+	Setting this to a value <vcs> will cause Git to interact with
+	the remote with the git-remote-<vcs> helper.
+
+remote.<name>.prune::
+	When set to true, fetching from this remote by default will also
+	remove any remote-tracking references that no longer exist on the
+	remote (as if the `--prune` option was given on the command line).
+	Overrides `fetch.prune` settings, if any.
 
 remotes.<group>::
 	The list of remotes which are fetched by "git remote update
-	<group>".  See gitlink:git-remote[1].
-
-repack.usedeltabaseoffset::
-	Allow gitlink:git-repack[1] to create packs that uses
-	delta-base offset.  Defaults to false.
-
-show.difftree::
-	The default gitlink:git-diff-tree[1] arguments to be used
-	for gitlink:git-show[1].
+	<group>".  See linkgit:git-remote[1].
+
+repack.useDeltaBaseOffset::
+	By default, linkgit:git-repack[1] creates packs that use
+	delta-base offset. If you need to share your repository with
+	Git older than version 1.4.4, either directly or via a dumb
+	protocol such as http, then you need to set this option to
+	"false" and repack. Access from old Git versions over the
+	native protocol are unaffected by this option.
+
+repack.packKeptObjects::
+	If set to true, makes `git repack` act as if
+	`--pack-kept-objects` was passed. See linkgit:git-repack[1] for
+	details. Defaults to `false` normally, but `true` if a bitmap
+	index is being written (either via `--write-bitmap-index` or
+	`repack.writeBitmaps`).
+
+repack.writeBitmaps::
+	When true, git will write a bitmap index when packing all
+	objects to disk (e.g., when `git repack -a` is run).  This
+	index can speed up the "counting objects" phase of subsequent
+	packs created for clones and fetches, at the cost of some disk
+	space and extra time spent on the initial repack.  Defaults to
+	false.
+
+rerere.autoUpdate::
+	When set to true, `git-rerere` updates the index with the
+	resulting contents after it cleanly resolves conflicts using
+	previously recorded resolution.  Defaults to false.
+
+rerere.enabled::
+	Activate recording of resolved conflicts, so that identical
+	conflict hunks can be resolved automatically, should they be
+	encountered again.  By default, linkgit:git-rerere[1] is
+	enabled if there is an `rr-cache` directory under the
+	`$GIT_DIR`, e.g. if "rerere" was previously used in the
+	repository.
+
+sendemail.identity::
+	A configuration identity. When given, causes values in the
+	'sendemail.<identity>' subsection to take precedence over
+	values in the 'sendemail' section. The default identity is
+	the value of 'sendemail.identity'.
+
+sendemail.smtpEncryption::
+	See linkgit:git-send-email[1] for description.  Note that this
+	setting is not subject to the 'identity' mechanism.
+
+sendemail.smtpssl (deprecated)::
+	Deprecated alias for 'sendemail.smtpEncryption = ssl'.
+
+sendemail.smtpsslcertpath::
+	Path to ca-certificates (either a directory or a single file).
+	Set it to an empty string to disable certificate verification.
+
+sendemail.<identity>.*::
+	Identity-specific versions of the 'sendemail.*' parameters
+	found below, taking precedence over those when the this
+	identity is selected, through command-line or
+	'sendemail.identity'.
+
+sendemail.aliasesFile::
+sendemail.aliasFileType::
+sendemail.annotate::
+sendemail.bcc::
+sendemail.cc::
+sendemail.ccCmd::
+sendemail.chainReplyTo::
+sendemail.confirm::

+sendemail.thread::
+sendemail.transferEncoding::
+sendemail.validate::
+sendemail.xmailer::
+	See linkgit:git-send-email[1] for description.
+
+sendemail.signedoffcc (deprecated)::
+	Deprecated alias for 'sendemail.signedoffbycc'.
 
 showbranch.default::
-	The default set of branches for gitlink:git-show-branch[1].
-	See gitlink:git-show-branch[1].
+	The default set of branches for linkgit:git-show-branch[1].
+	See linkgit:git-show-branch[1].
+
+status.relativePaths::
+	By default, linkgit:git-status[1] shows paths relative to the
+	current directory. Setting this variable to `false` shows paths
+	relative to the repository root (this was the default for Git
+	prior to v1.5.4).
+
+status.short::
+	Set to true to enable --short by default in linkgit:git-status[1].
+	The option --no-short takes precedence over this variable.
+
+status.branch::
+	Set to true to enable --branch by default in linkgit:git-status[1].
+	The option --no-branch takes precedence over this variable.
+
+status.displayCommentPrefix::
+	If set to true, linkgit:git-status[1] will insert a comment
+	prefix before each output line (starting with
+	`core.commentChar`, i.e. `#` by default). This was the
+	behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
+	Defaults to false.
+
+status.showUntrackedFiles::
+	By default, linkgit:git-status[1] and linkgit:git-commit[1] show
+	files which are not currently tracked by Git. Directories which
+	contain only untracked files, are shown with the directory name
+	only. Showing untracked files means that Git needs to lstat() all
+	the files in the whole repository, which might be slow on some
+	systems. So, this variable controls how the commands displays
+	the untracked files. Possible values are:
++
+--
+* `no` - Show no untracked files.
+* `normal` - Show untracked files and directories.
+* `all` - Show also individual files in untracked directories.
+--
++
+If this variable is not specified, it defaults to 'normal'.
+This variable can be overridden with the -u|--untracked-files option
+of linkgit:git-status[1] and linkgit:git-commit[1].
+
+status.submoduleSummary::
+	Defaults to false.
+	If this is set to a non zero number or true (identical to -1 or an
+	unlimited number), the submodule summary will be enabled and a
+	summary of commits for modified submodules will be shown (see
+	--summary-limit option of linkgit:git-submodule[1]). Please note
+	that the summary output command will be suppressed for all
+	submodules when `diff.ignoreSubmodules` is set to 'all' or only
+	for those submodules where `submodule.<name>.ignore=all`. The only
+	exception to that rule is that status and commit will show staged
+	submodule changes. To
+	also view the summary for ignored submodules you can either use
+	the --ignore-submodules=dirty command-line option or the 'git
+	submodule summary' command, which shows a similar output but does
+	not honor these settings.
+
+submodule.<name>.path::
+submodule.<name>.url::
+	The path within this project and URL for a submodule. These
+	variables are initially populated by 'git submodule init'. See
+	linkgit:git-submodule[1] and linkgit:gitmodules[5] for
+	details.
+
+submodule.<name>.update::
+	The default update procedure for a submodule. This variable
+	is populated by `git submodule init` from the
+	linkgit:gitmodules[5] file. See description of 'update'
+	command in linkgit:git-submodule[1].
+
+submodule.<name>.branch::
+	The remote branch name for a submodule, used by `git submodule
+	update --remote`.  Set this option to override the value found in
+	the `.gitmodules` file.  See linkgit:git-submodule[1] and
+	linkgit:gitmodules[5] for details.
+
+submodule.<name>.fetchRecurseSubmodules::
+	This option can be used to control recursive fetching of this
+	submodule. It can be overridden by using the --[no-]recurse-submodules
+	command-line option to "git fetch" and "git pull".
+	This setting will override that from in the linkgit:gitmodules[5]
+	file.
+
+submodule.<name>.ignore::
+	Defines under what circumstances "git status" and the diff family show
+	a submodule as modified. When set to "all", it will never be considered
+	modified (but it will nonetheless show up in the output of status and
+	commit when it has been staged), "dirty" will ignore all changes
+	to the submodules work tree and
+	takes only differences between the HEAD of the submodule and the commit
+	recorded in the superproject into account. "untracked" will additionally
+	let submodules with modified tracked files in their work tree show up.
+	Using "none" (the default when this option is not set) also shows
+	submodules that have untracked files in their work tree as changed.
+	This setting overrides any setting made in .gitmodules for this submodule,
+	both settings can be overridden on the command line by using the
+	"--ignore-submodules" option. The 'git submodule' commands are not
+	affected by this setting.
+
+tag.sort::
+	This variable controls the sort ordering of tags when displayed by
+	linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
+	value of this variable will be used as the default.
 
 tar.umask::
-	By default, gitlink:git-tar-tree[1] sets file and directories modes
-	to 0666 or 0777. While this is both useful and acceptable for projects
-	such as the Linux Kernel, it might be excessive for other projects.
-	With this variable, it becomes possible to tell
-	gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
-	The special value "user" indicates that the user's current umask will
-	be used. This should be enough for most projects, as it will lead to
-	the same permissions as gitlink:git-checkout[1] would use. The default
-	value remains 0, which means world read-write.
+	This variable can be used to restrict the permission bits of
+	tar archive entries.  The default is 0002, which turns off the
+	world write bit.  The special value "user" indicates that the
+	archiving user's umask will be used instead.  See umask(2) and
+	linkgit:git-archive[1].
+
+transfer.fsckObjects::
+	When `fetch.fsckObjects` or `receive.fsckObjects` are
+	not set, the value of this variable is used instead.
+	Defaults to false.
+
+transfer.hideRefs::
+	String(s) `receive-pack` and `upload-pack` use to decide which
+	refs to omit from their initial advertisements.  Use more than
+	one definition to specify multiple prefix strings. A ref that is
+	under the hierarchies listed in the value of this variable is
+	excluded, and is hidden when responding to `git push` or `git
+	fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
+	program-specific versions of this config.
++
+You may also include a `!` in front of the ref name to negate the entry,
+explicitly exposing it, even if an earlier entry marked it as hidden.
+If you have multiple hideRefs values, later entries override earlier ones
+(and entries in more-specific config files override less-specific ones).
+
+transfer.unpackLimit::
+	When `fetch.unpackLimit` or `receive.unpackLimit` are
+	not set, the value of this variable is used instead.
+	The default value is 100.
+
+uploadarchive.allowUnreachable::
+	If true, allow clients to use `git archive --remote` to request
+	any tree, whether reachable from the ref tips or not. See the
+	discussion in the `SECURITY` section of
+	linkgit:git-upload-archive[1] for more details. Defaults to
+	`false`.
+
+uploadpack.hideRefs::
+	This variable is the same as `transfer.hideRefs`, but applies
+	only to `upload-pack` (and so affects only fetches, not pushes).
+	An attempt to fetch a hidden ref by `git fetch` will fail.  See
+	also `uploadpack.allowTipSHA1InWant`.
+
+uploadpack.allowTipSHA1InWant::
+	When `uploadpack.hideRefs` is in effect, allow `upload-pack`
+	to accept a fetch request that asks for an object at the tip
+	of a hidden ref (by default, such a request is rejected).
+	see also `uploadpack.hideRefs`.
+
+uploadpack.allowReachableSHA1InWant::
+	Allow `upload-pack` to accept a fetch request that asks for an
+	object that is reachable from any ref tip. However, note that
+	calculating object reachability is computationally expensive.
+	Defaults to `false`.
+
+uploadpack.keepAlive::
+	When `upload-pack` has started `pack-objects`, there may be a
+	quiet period while `pack-objects` prepares the pack. Normally
+	it would output progress information, but if `--quiet` was used
+	for the fetch, `pack-objects` will output nothing at all until
+	the pack data begins. Some clients and networks may consider
+	the server to be hung and give up. Setting this option instructs
+	`upload-pack` to send an empty keepalive packet every
+	`uploadpack.keepAlive` seconds. Setting this option to 0
+	disables keepalive packets entirely. The default is 5 seconds.
+
+url.<base>.insteadOf::
+	Any URL that starts with this value will be rewritten to
+	start, instead, with <base>. In cases where some site serves a
+	large number of repositories, and serves them with multiple
+	access methods, and some users need to use different access
+	methods, this feature allows people to specify any of the
+	equivalent URLs and have Git automatically rewrite the URL to
+	the best alternative for the particular user, even for a
+	never-before-seen repository on the site.  When more than one
+	insteadOf strings match a given URL, the longest match is used.
+
+url.<base>.pushInsteadOf::
+	Any URL that starts with this value will not be pushed to;
+	instead, it will be rewritten to start with <base>, and the
+	resulting URL will be pushed to. In cases where some site serves
+	a large number of repositories, and serves them with multiple
+	access methods, some of which do not allow push, this feature
+	allows people to specify a pull-only URL and have Git
+	automatically use an appropriate URL to push, even for a
+	never-before-seen repository on the site.  When more than one
+	pushInsteadOf strings match a given URL, the longest match is
+	used.  If a remote has an explicit pushurl, Git will ignore this
+	setting for that remote.
 
 user.email::
 	Your email address to be recorded in any newly created commits.
-	Can be overridden by the 'GIT_AUTHOR_EMAIL' and 'GIT_COMMITTER_EMAIL'
-	environment variables.  See gitlink:git-commit-tree[1].
+	Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and

 user.name::
 	Your full name to be recorded in any newly created commits.
 	Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
-	environment variables.  See gitlink:git-commit-tree[1].
-
-user.signingkey::
-	If gitlink:git-tag[1] is not selecting the key you want it to
-	automatically when creating a signed tag, you can override the
-	default selection with this variable.  This option is passed
-	unchanged to gpg's --local-user parameter, so you may specify a key
-	using any method that gpg supports.
-
-whatchanged.difftree::
-	The default gitlink:git-diff-tree[1] arguments to be used
-	for gitlink:git-whatchanged[1].
-
-imap::
-	The configuration variables in the 'imap' section are described
-	in gitlink:git-imap-send[1].
-
-receive.unpackLimit::
-	If the number of objects received in a push is below this
-	limit then the objects will be unpacked into loose object
-	files. However if the number of received objects equals or
-	exceeds this limit then the received pack will be stored as
-	a pack, after adding any missing delta bases.  Storing the
-	pack from a push can make the push operation complete faster,
-	especially on slow filesystems.
-
-receive.denyNonFastForwards::
-	If set to true, git-receive-pack will deny a ref update which is
-	not a fast forward. Use this to prevent such an update via a push,
-	even if that push is forced. This configuration variable is
-	set when initializing a shared repository.

+
+user.signingKey::
+	If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
+	key you want it to automatically when creating a signed tag or
+	commit, you can override the default selection with this variable.
+	This option is passed unchanged to gpg's --local-user parameter,
+	so you may specify a key using any method that gpg supports.
+
+versionsort.prereleaseSuffix::
+	When version sort is used in linkgit:git-tag[1], prerelease
+	tags (e.g. "1.0-rc1") may appear after the main release
+	"1.0". By specifying the suffix "-rc" in this variable,
+	"1.0-rc1" will appear before "1.0".
++
+This variable can be specified multiple times, once per suffix. The
+order of suffixes in the config file determines the sorting order
+(e.g. if "-pre" appears before "-rc" in the config file then 1.0-preXX
+is sorted before 1.0-rcXX). The sorting order between different
+suffixes is undefined if they are in multiple config files.
+
+web.browser::
+	Specify a web browser that may be used by some commands.
+	Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
+	may use it.

-"git" can mean anything, depending on your mood.
-
- - random three-letter combination that is pronounceable, and not
-   actually used by any common UNIX command.  The fact that it is a
-   mispronunciation of "get" may or may not be relevant.
- - stupid. contemptible and despicable. simple. Take your pick from the
-   dictionary of slang.

-   works for you. Angels sing, and a light suddenly fills the room.
- - "goddamn idiotic truckload of sh*t": when it breaks
-
-This is a (not so) stupid but extremely fast directory content manager.
-It doesn't do a whole lot at its core, but what it 'does' do is track
-directory contents efficiently.
-
-There are two object abstractions: the "object database", and the
-"current directory cache" aka "index".
-
-The Object Database
-~~~~~~~~~~~~~~~~~~~
-The object database is literally just a content-addressable collection
-of objects.  All objects are named by their content, which is
-approximated by the SHA1 hash of the object itself.  Objects may refer
-to other objects (by referencing their SHA1 hash), and so you can
-build up a hierarchy of objects.
-
-All objects have a statically determined "type" aka "tag", which is
-determined at object creation time, and which identifies the format of
-the object (i.e. how it is used, and how it can refer to other
-objects).  There are currently four different object types: "blob",
-"tree", "commit" and "tag".
-
-A "blob" object cannot refer to any other object, and is, like the type
-implies, a pure storage object containing some user data.  It is used to
-actually store the file data, i.e. a blob object is associated with some
-particular version of some file.
-
-A "tree" object is an object that ties one or more "blob" objects into a
-directory structure. In addition, a tree object can refer to other tree
-objects, thus creating a directory hierarchy.
-
-A "commit" object ties such directory hierarchies together into
-a DAG of revisions - each "commit" is associated with exactly one tree
-(the directory hierarchy at the time of the commit). In addition, a
-"commit" refers to one or more "parent" commit objects that describe the
-history of how we arrived at that directory hierarchy.
-
-As a special case, a commit object with no parents is called the "root"
-object, and is the point of an initial project commit.  Each project
-must have at least one root, and while you can tie several different
-root objects together into one project by creating a commit object which
-has two or more separate roots as its ultimate parents, that's probably
-just going to confuse people.  So aim for the notion of "one root object
-per project", even if git itself does not enforce that.
-
-A "tag" object symbolically identifies and can be used to sign other
-objects. It contains the identifier and type of another object, a
-symbolic name (of course!) and, optionally, a signature.
-
-Regardless of object type, all objects share the following
-characteristics: they are all deflated with zlib, and have a header
-that not only specifies their type, but also provides size information
-about the data in the object.  It's worth noting that the SHA1 hash
-that is used to name the object is the hash of the original data
-plus this header, so `sha1sum` 'file' does not match the object name
-for 'file'.
-(Historical note: in the dawn of the age of git the hash
-was the sha1 of the 'compressed' object.)
-
-As a result, the general consistency of an object can always be tested
-independently of the contents or the type of the object: all objects can
-be validated by verifying that (a) their hashes match the content of the
-file and (b) the object successfully inflates to a stream of bytes that
-forms a sequence of <ascii type without space> + <space> + <ascii decimal
-size> + <byte\0> + <binary object data>.
-
-The structured objects can further have their structure and
-connectivity to other objects verified. This is generally done with
-the `git-fsck` program, which generates a full dependency graph
-of all objects, and verifies their internal consistency (in addition
-to just verifying their superficial consistency through the hash).
-
-The object types in some more detail:
-
-Blob Object
-~~~~~~~~~~~
-A "blob" object is nothing but a binary blob of data, and doesn't
-refer to anything else.  There is no signature or any other
-verification of the data, so while the object is consistent (it 'is'
-indexed by its sha1 hash, so the data itself is certainly correct), it
-has absolutely no other attributes.  No name associations, no
-permissions.  It is purely a blob of data (i.e. normally "file
-contents").
-
-In particular, since the blob is entirely defined by its data, if two
-files in a directory tree (or in multiple different versions of the
-repository) have the same contents, they will share the same blob
-object. The object is totally independent of its location in the
-directory tree, and renaming a file does not change the object that
-file is associated with in any way.
-
-A blob is typically created when gitlink:git-update-index[1]
-(or gitlink:git-add[1]) is run, and its data can be accessed by
-gitlink:git-cat-file[1].
-
-Tree Object
-~~~~~~~~~~~
-The next hierarchical object type is the "tree" object.  A tree object
-is a list of mode/name/blob data, sorted by name.  Alternatively, the
-mode data may specify a directory mode, in which case instead of
-naming a blob, that name is associated with another TREE object.
-
-Like the "blob" object, a tree object is uniquely determined by the
-set contents, and so two separate but identical trees will always
-share the exact same object. This is true at all levels, i.e. it's
-true for a "leaf" tree (which does not refer to any other trees, only
-blobs) as well as for a whole subdirectory.
-
-For that reason a "tree" object is just a pure data abstraction: it
-has no history, no signatures, no verification of validity, except
-that since the contents are again protected by the hash itself, we can
-trust that the tree is immutable and its contents never change.
-
-So you can trust the contents of a tree to be valid, the same way you
-can trust the contents of a blob, but you don't know where those
-contents 'came' from.
-
-Side note on trees: since a "tree" object is a sorted list of
-"filename+content", you can create a diff between two trees without
-actually having to unpack two trees.  Just ignore all common parts,
-and your diff will look right.  In other words, you can effectively
-(and efficiently) tell the difference between any two random trees by
-O(n) where "n" is the size of the difference, rather than the size of
-the tree.
-
-Side note 2 on trees: since the name of a "blob" depends entirely and
-exclusively on its contents (i.e. there are no names or permissions
-involved), you can see trivial renames or permission changes by
-noticing that the blob stayed the same.  However, renames with data
-changes need a smarter "diff" implementation.
-
-A tree is created with gitlink:git-write-tree[1] and
-its data can be accessed by gitlink:git-ls-tree[1].
-Two trees can be compared with gitlink:git-diff-tree[1].
-
-Commit Object
-~~~~~~~~~~~~~
-The "commit" object is an object that introduces the notion of
-history into the picture.  In contrast to the other objects, it
-doesn't just describe the physical state of a tree, it describes how
-we got there, and why.
-
-A "commit" is defined by the tree-object that it results in, the
-parent commits (zero, one or more) that led up to that point, and a
-comment on what happened.  Again, a commit is not trusted per se:
-the contents are well-defined and "safe" due to the cryptographically
-strong signatures at all levels, but there is no reason to believe
-that the tree is "good" or that the merge information makes sense.
-The parents do not have to actually have any relationship with the
-result, for example.
-
-Note on commits: unlike real SCM's, commits do not contain
-rename information or file mode change information.  All of that is
-implicit in the trees involved (the result tree, and the result trees
-of the parents), and describing that makes no sense in this idiotic
-file manager.
-
-A commit is created with gitlink:git-commit-tree[1] and
-its data can be accessed by gitlink:git-cat-file[1].
-
-Trust
-~~~~~
-An aside on the notion of "trust". Trust is really outside the scope
-of "git", but it's worth noting a few things.  First off, since
-everything is hashed with SHA1, you 'can' trust that an object is
-intact and has not been messed with by external sources.  So the name
-of an object uniquely identifies a known state - just not a state that
-you may want to trust.
-
-Furthermore, since the SHA1 signature of a commit refers to the
-SHA1 signatures of the tree it is associated with and the signatures
-of the parent, a single named commit specifies uniquely a whole set
-of history, with full contents.  You can't later fake any step of the
-way once you have the name of a commit.
-
-So to introduce some real trust in the system, the only thing you need
-to do is to digitally sign just 'one' special note, which includes the
-name of a top-level commit.  Your digital signature shows others
-that you trust that commit, and the immutability of the history of
-commits tells others that they can trust the whole history.
-
-In other words, you can easily validate a whole archive by just
-sending out a single email that tells the people the name (SHA1 hash)
-of the top commit, and digitally sign that email using something
-like GPG/PGP.
-
-To assist in this, git also provides the tag object...
-
-Tag Object
-~~~~~~~~~~
-Git provides the "tag" object to simplify creating, managing and
-exchanging symbolic and signed tokens.  The "tag" object at its
-simplest simply symbolically identifies another object by containing
-the sha1, type and symbolic name.
-
-However it can optionally contain additional signature information
-(which git doesn't care about as long as there's less than 8k of
-it). This can then be verified externally to git.
-
-Note that despite the tag features, "git" itself only handles content
-integrity; the trust framework (and signature provision and
-verification) has to come from outside.
-
-A tag is created with gitlink:git-mktag[1],
-its data can be accessed by gitlink:git-cat-file[1],
-and the signature can be verified by
-gitlink:git-verify-tag[1].
-
-
-The "index" aka "Current Directory Cache"
------------------------------------------
-The index is a simple binary file, which contains an efficient
-representation of a virtual directory content at some random time.  It
-does so by a simple array that associates a set of names, dates,
-permissions and content (aka "blob") objects together.  The cache is
-always kept ordered by name, and names are unique (with a few very
-specific rules) at any point in time, but the cache has no long-term
-meaning, and can be partially updated at any time.
-
-In particular, the index certainly does not need to be consistent with
-the current directory contents (in fact, most operations will depend on
-different ways to make the index 'not' be consistent with the directory
-hierarchy), but it has three very important attributes:
-
-'(a) it can re-generate the full state it caches (not just the
-directory structure: it contains pointers to the "blob" objects so
-that it can regenerate the data too)'
-
-As a special case, there is a clear and unambiguous one-way mapping
-from a current directory cache to a "tree object", which can be
-efficiently created from just the current directory cache without
-actually looking at any other data.  So a directory cache at any one
-time uniquely specifies one and only one "tree" object (but has
-additional data to make it easy to match up that tree object with what
-has happened in the directory)
-
-'(b) it has efficient methods for finding inconsistencies between that
-cached state ("tree object waiting to be instantiated") and the
-current state.'
-
-'(c) it can additionally efficiently represent information about merge
-conflicts between different tree objects, allowing each pathname to be
-associated with sufficient information about the trees involved that
-you can create a three-way merge between them.'
-
-Those are the three ONLY things that the directory cache does.  It's a
-cache, and the normal operation is to re-generate it completely from a
-known tree object, or update/compare it with a live tree that is being
-developed.  If you blow the directory cache away entirely, you generally
-haven't lost any information as long as you have the name of the tree
-that it described.
-
-At the same time, the index is at the same time also the
-staging area for creating new trees, and creating a new tree always
-involves a controlled modification of the index file.  In particular,
-the index file can have the representation of an intermediate tree that
-has not yet been instantiated.  So the index can be thought of as a
-write-back cache, which can contain dirty information that has not yet
-been written back to the backing store.
-
-
-
-The Workflow
-------------
-Generally, all "git" operations work on the index file. Some operations
-work *purely* on the index file (showing the current state of the
-index), but most operations move data to and from the index file. Either
-from the database or from the working directory. Thus there are four
-main combinations:
-
-1) working directory -> index
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You update the index with information from the working directory with
-the gitlink:git-update-index[1] command.  You
-generally update the index information by just specifying the filename
-you want to update, like so:
-
-	git-update-index filename
-
-but to avoid common mistakes with filename globbing etc, the command
-will not normally add totally new entries or remove old entries,
-i.e. it will normally just update existing cache entries.
-
-To tell git that yes, you really do realize that certain files no
-longer exist, or that new files should be added, you
-should use the `--remove` and `--add` flags respectively.
-
-NOTE! A `--remove` flag does 'not' mean that subsequent filenames will
-necessarily be removed: if the files still exist in your directory
-structure, the index will be updated with their new status, not
-removed. The only thing `--remove` means is that update-cache will be
-considering a removed file to be a valid thing, and if the file really
-does not exist any more, it will update the index accordingly.
-
-As a special case, you can also do `git-update-index --refresh`, which
-will refresh the "stat" information of each index to match the current
-stat information. It will 'not' update the object status itself, and
-it will only update the fields that are used to quickly test whether
-an object still matches its old backing store object.
-
-2) index -> object database
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You write your current index file to a "tree" object with the program
-
-	git-write-tree
-
-that doesn't come with any options - it will just write out the
-current index into the set of tree objects that describe that state,
-and it will return the name of the resulting top-level tree. You can
-use that tree to re-generate the index at any time by going in the
-other direction:
-
-3) object database -> index
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You read a "tree" file from the object database, and use that to
-populate (and overwrite - don't do this if your index contains any
-unsaved state that you might want to restore later!) your current
-index.  Normal operation is just
-
-		git-read-tree <sha1 of tree>
-
-and your index file will now be equivalent to the tree that you saved
-earlier. However, that is only your 'index' file: your working
-directory contents have not been modified.
-
-4) index -> working directory
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You update your working directory from the index by "checking out"
-files. This is not a very common operation, since normally you'd just
-keep your files updated, and rather than write to your working
-directory, you'd tell the index files about the changes in your
-working directory (i.e. `git-update-index`).
-
-However, if you decide to jump to a new version, or check out somebody
-else's version, or just restore a previous tree, you'd populate your
-index file with read-tree, and then you need to check out the result
-with
-
-		git-checkout-index filename
-
-or, if you want to check out all of the index, use `-a`.
-
-NOTE! git-checkout-index normally refuses to overwrite old files, so
-if you have an old version of the tree already checked out, you will
-need to use the "-f" flag ('before' the "-a" flag or the filename) to
-'force' the checkout.
-
-
-Finally, there are a few odds and ends which are not purely moving
-from one representation to the other:
-
-5) Tying it all together
-~~~~~~~~~~~~~~~~~~~~~~~~
-To commit a tree you have instantiated with "git-write-tree", you'd
-create a "commit" object that refers to that tree and the history
-behind it - most notably the "parent" commits that preceded it in
-history.
-
-Normally a "commit" has one parent: the previous state of the tree
-before a certain change was made. However, sometimes it can have two
-or more parent commits, in which case we call it a "merge", due to the
-fact that such a commit brings together ("merges") two or more
-previous states represented by other commits.
-
-In other words, while a "tree" represents a particular directory state
-of a working directory, a "commit" represents that state in "time",
-and explains how we got there.
-
-You create a commit object by giving it the tree that describes the
-state at the time of the commit, and a list of parents:
-
-	git-commit-tree <tree> -p <parent> [-p <parent2> ..]
-
-and then giving the reason for the commit on stdin (either through
-redirection from a pipe or file, or by just typing it at the tty).
-
-git-commit-tree will return the name of the object that represents
-that commit, and you should save it away for later use. Normally,
-you'd commit a new `HEAD` state, and while git doesn't care where you
-save the note about that state, in practice we tend to just write the
-result to the file pointed at by `.git/HEAD`, so that we can always see
-what the last committed state was.
-
-Here is an ASCII art by Jon Loeliger that illustrates how
-various pieces fit together.

-                    +-----------+
-
-------------
-
-
-6) Examining the data
-~~~~~~~~~~~~~~~~~~~~~
-
-You can examine the data represented in the object database and the
-index with various helper tools. For every object, you can use
-gitlink:git-cat-file[1] to examine details about the
-object:
-
-		git-cat-file -t <objectname>
-
-shows the type of the object, and once you have the type (which is
-usually implicit in where you find the object), you can use
-
-		git-cat-file blob|tree|commit|tag <objectname>
-
-to show its contents. NOTE! Trees have binary content, and as a result
-there is a special helper for showing that content, called
-`git-ls-tree`, which turns the binary content into a more easily
-readable form.
-
-It's especially instructive to look at "commit" objects, since those
-tend to be small and fairly self-explanatory. In particular, if you
-follow the convention of having the top commit name in `.git/HEAD`,
-you can do
-
-		git-cat-file commit HEAD
-
-to see what the top commit was.
-
-7) Merging multiple trees
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Git helps you do a three-way merge, which you can expand to n-way by
-repeating the merge procedure arbitrary times until you finally
-"commit" the state.  The normal situation is that you'd only do one
-three-way merge (two parents), and commit it, but if you like to, you
-can do multiple parents in one go.
-
-To do a three-way merge, you need the two sets of "commit" objects
-that you want to merge, use those to find the closest common parent (a
-third "commit" object), and then use those commit objects to find the
-state of the directory ("tree" object) at these points.
-
-To get the "base" for the merge, you first look up the common parent
-of two commits with
-
-		git-merge-base <commit1> <commit2>
-
-which will return you the commit they are both based on.  You should
-now look up the "tree" objects of those commits, which you can easily
-do with (for example)
-
-		git-cat-file commit <commitname> | head -1
-
-since the tree object information is always the first line in a commit
-object.
-
-Once you know the three trees you are going to merge (the one
-"original" tree, aka the common case, and the two "result" trees, aka
-the branches you want to merge), you do a "merge" read into the
-index. This will complain if it has to throw away your old index contents, so you should
-make sure that you've committed those - in fact you would normally
-always do a merge against your last commit (which should thus match
-what you have in your current index anyway).
-
-To do the merge, do
-
-		git-read-tree -m -u <origtree> <yourtree> <targettree>
-
-which will do all trivial merge operations for you directly in the
-index file, and you can just write the result out with
-`git-write-tree`.
-
-Historical note.  We did not have `-u` facility when this
-section was first written, so we used to warn that
-the merge is done in the index file, not in your
-working tree, and your working tree will not match your
-index after this step.
-This is no longer true.  The above command, thanks to `-u`
-option, updates your working tree with the merge results for
-paths that have been trivially merged.
-
-
-8) Merging multiple trees, continued
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Sadly, many merges aren't trivial. If there are files that have
-been added.moved or removed, or if both branches have modified the
-same file, you will be left with an index tree that contains "merge
-entries" in it. Such an index tree can 'NOT' be written out to a tree
-object, and you will have to resolve any such merge clashes using
-other tools before you can write out the result.
-
-You can examine such index state with `git-ls-files --unmerged`
-command.  An example:
-
-------------------------------------------------
-$ git-read-tree -m $orig HEAD $target
-$ git-ls-files --unmerged
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1	hello.c
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2	hello.c
-100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello.c
-------------------------------------------------
-
-Each line of the `git-ls-files --unmerged` output begins with
-the blob mode bits, blob SHA1, 'stage number', and the
-filename.  The 'stage number' is git's way to say which tree it
-came from: stage 1 corresponds to `$orig` tree, stage 2 `HEAD`
-tree, and stage3 `$target` tree.
-
-Earlier we said that trivial merges are done inside
-`git-read-tree -m`.  For example, if the file did not change
-from `$orig` to `HEAD` nor `$target`, or if the file changed
-from `$orig` to `HEAD` and `$orig` to `$target` the same way,
-obviously the final outcome is what is in `HEAD`.  What the
-above example shows is that file `hello.c` was changed from
-`$orig` to `HEAD` and `$orig` to `$target` in a different way.
-You could resolve this by running your favorite 3-way merge
-program, e.g.  `diff3` or `merge`, on the blob objects from
-these three stages yourself, like this:
-
-------------------------------------------------
-$ git-cat-file blob 263414f... >hello.c~1
-$ git-cat-file blob 06fa6a2... >hello.c~2
-$ git-cat-file blob cc44c73... >hello.c~3
-$ merge hello.c~2 hello.c~1 hello.c~3
-------------------------------------------------
-
-This would leave the merge result in `hello.c~2` file, along
-with conflict markers if there are conflicts.  After verifying
-the merge result makes sense, you can tell git what the final
-merge result for this file is by:
-
-	mv -f hello.c~2 hello.c
-	git-update-index hello.c
-
-When a path is in unmerged state, running `git-update-index` for
-that path tells git to mark the path resolved.
-
-The above is the description of a git merge at the lowest level,
-to help you understand what conceptually happens under the hood.
-In practice, nobody, not even git itself, uses three `git-cat-file`
-for this.  There is `git-merge-index` program that extracts the
-stages to temporary files and calls a "merge" script on it:
-
-	git-merge-index git-merge-one-file hello.c
-
-and that is what higher level `git merge -s resolve` is implemented
-with.

-A git core tutorial for developers
-==================================
-
-Introduction
-------------
-
-This is trying to be a short tutorial on setting up and using a git
-repository, mainly because being hands-on and using explicit examples is
-often the best way of explaining what is going on.
-
-In normal life, most people wouldn't use the "core" git programs
-directly, but rather script around them to make them more palatable. 
-Understanding the core git stuff may help some people get those scripts
-done, though, and it may also be instructive in helping people
-understand what it is that the higher-level helper scripts are actually
-doing. 
-
-The core git is often called "plumbing", with the prettier user
-interfaces on top of it called "porcelain". You may not want to use the
-plumbing directly very often, but it can be good to know what the
-plumbing does for when the porcelain isn't flushing.
-
-The material presented here often goes deep describing how things
-work internally.  If you are mostly interested in using git as a
-SCM, you can skip them during your first pass.
-
-[NOTE]
-And those "too deep" descriptions are often marked as Note.
-
-[NOTE]
-If you are already familiar with another version control system,
-like CVS, you may want to take a look at
-link:everyday.html[Everyday GIT in 20 commands or so] first
-before reading this.
-
-
-Creating a git repository
--------------------------
-
-Creating a new git repository couldn't be easier: all git repositories start
-out empty, and the only thing you need to do is find yourself a
-subdirectory that you want to use as a working tree - either an empty
-one for a totally new project, or an existing working tree that you want
-to import into git. 
-
-For our first example, we're going to start a totally new repository from
-scratch, with no pre-existing files, and we'll call it `git-tutorial`.
-To start up, create a subdirectory for it, change into that
-subdirectory, and initialize the git infrastructure with `git-init`:
-
-------------------------------------------------
-$ mkdir git-tutorial
-$ cd git-tutorial
-$ git-init
-------------------------------------------------
-
-to which git will reply
-
-----------------
-Initialized empty Git repository in .git/
-----------------
-
-which is just git's way of saying that you haven't been doing anything
-strange, and that it will have created a local `.git` directory setup for
-your new project. You will now have a `.git` directory, and you can
-inspect that with `ls`. For your new empty project, it should show you
-three entries, among other things:
-
- - a file called `HEAD`, that has `ref: refs/heads/master` in it.
-   This is similar to a symbolic link and points at
-   `refs/heads/master` relative to the `HEAD` file.
-+
-Don't worry about the fact that the file that the `HEAD` link points to
-doesn't even exist yet -- you haven't created the commit that will
-start your `HEAD` development branch yet.
-
- - a subdirectory called `objects`, which will contain all the
-   objects of your project. You should never have any real reason to
-   look at the objects directly, but you might want to know that these
-   objects are what contains all the real 'data' in your repository.
-
- - a subdirectory called `refs`, which contains references to objects.
-
-In particular, the `refs` subdirectory will contain two other
-subdirectories, named `heads` and `tags` respectively. They do
-exactly what their names imply: they contain references to any number
-of different 'heads' of development (aka 'branches'), and to any
-'tags' that you have created to name specific versions in your
-repository.
-
-One note: the special `master` head is the default branch, which is
-why the `.git/HEAD` file was created points to it even if it
-doesn't yet exist. Basically, the `HEAD` link is supposed to always
-point to the branch you are working on right now, and you always
-start out expecting to work on the `master` branch.
-
-However, this is only a convention, and you can name your branches
-anything you want, and don't have to ever even 'have' a `master`
-branch. A number of the git tools will assume that `.git/HEAD` is
-valid, though.
-
-[NOTE]
-An 'object' is identified by its 160-bit SHA1 hash, aka 'object name',
-and a reference to an object is always the 40-byte hex
-representation of that SHA1 name. The files in the `refs`
-subdirectory are expected to contain these hex references
-(usually with a final `\'\n\'` at the end), and you should thus
-expect to see a number of 41-byte files containing these
-references in these `refs` subdirectories when you actually start
-populating your tree.
-
-[NOTE]
-An advanced user may want to take a look at the
-link:repository-layout.html[repository layout] document
-after finishing this tutorial.
-
-You have now created your first git repository. Of course, since it's
-empty, that's not very useful, so let's start populating it with data.
-
-
-Populating a git repository
----------------------------
-
-We'll keep this simple and stupid, so we'll start off with populating a
-few trivial files just to get a feel for it.
-
-Start off with just creating any random files that you want to maintain
-in your git repository. We'll start off with a few bad examples, just to
-get a feel for how this works:
-
-------------------------------------------------
-$ echo "Hello World" >hello
-$ echo "Silly example" >example
-------------------------------------------------
-
-you have now created two files in your working tree (aka 'working directory'),
-but to actually check in your hard work, you will have to go through two steps:
-
- - fill in the 'index' file (aka 'cache') with the information about your
-   working tree state.
-
- - commit that index file as an object.
-
-The first step is trivial: when you want to tell git about any changes
-to your working tree, you use the `git-update-index` program. That
-program normally just takes a list of filenames you want to update, but
-to avoid trivial mistakes, it refuses to add new entries to the index
-(or remove existing ones) unless you explicitly tell it that you're
-adding a new entry with the `\--add` flag (or removing an entry with the
-`\--remove`) flag.
-
-So to populate the index with the two files you just created, you can do
-
-------------------------------------------------
-$ git-update-index --add hello example
-------------------------------------------------
-
-and you have now told git to track those two files.
-
-In fact, as you did that, if you now look into your object directory,
-you'll notice that git will have added two new objects to the object
-database. If you did exactly the steps above, you should now be able to do
-
-
-----------------
-$ ls .git/objects/??/*
-----------------
-
-and see two files:
-
-----------------
-.git/objects/55/7db03de997c86a4a028e1ebd3a1ceb225be238 
-.git/objects/f2/4c74a2e500f5ee1332c86b94199f52b1d1d962
-----------------
-
-which correspond with the objects with names of `557db...` and
-`f24c7...` respectively.
-
-If you want to, you can use `git-cat-file` to look at those objects, but
-you'll have to use the object name, not the filename of the object:
-
-----------------
-$ git-cat-file -t 557db03de997c86a4a028e1ebd3a1ceb225be238
-----------------
-
-where the `-t` tells `git-cat-file` to tell you what the "type" of the
-object is. git will tell you that you have a "blob" object (i.e., just a
-regular file), and you can see the contents with
-
-----------------
-$ git-cat-file "blob" 557db03
-----------------
-
-which will print out "Hello World". The object `557db03` is nothing
-more than the contents of your file `hello`.
-
-[NOTE]
-Don't confuse that object with the file `hello` itself. The
-object is literally just those specific *contents* of the file, and
-however much you later change the contents in file `hello`, the object
-we just looked at will never change. Objects are immutable.
-
-[NOTE]
-The second example demonstrates that you can
-abbreviate the object name to only the first several
-hexadecimal digits in most places.
-
-Anyway, as we mentioned previously, you normally never actually take a
-look at the objects themselves, and typing long 40-character hex
-names is not something you'd normally want to do. The above digression
-was just to show that `git-update-index` did something magical, and
-actually saved away the contents of your files into the git object
-database.
-
-Updating the index did something else too: it created a `.git/index`
-file. This is the index that describes your current working tree, and
-something you should be very aware of. Again, you normally never worry
-about the index file itself, but you should be aware of the fact that
-you have not actually really "checked in" your files into git so far,
-you've only *told* git about them.
-
-However, since git knows about them, you can now start using some of the
-most basic git commands to manipulate the files or look at their status. 
-
-In particular, let's not even check in the two files into git yet, we'll
-start off by adding another line to `hello` first:
-
-------------------------------------------------
-$ echo "It's a new day for git" >>hello
-------------------------------------------------
-
-and you can now, since you told git about the previous state of `hello`, ask
-git what has changed in the tree compared to your old index, using the
-`git-diff-files` command:
-
-------------
-$ git-diff-files
-------------
-
-Oops. That wasn't very readable. It just spit out its own internal
-version of a `diff`, but that internal version really just tells you
-that it has noticed that "hello" has been modified, and that the old object
-contents it had have been replaced with something else.
-
-To make it readable, we can tell git-diff-files to output the
-differences as a patch, using the `-p` flag:
-
-------------
-$ git-diff-files -p
-diff --git a/hello b/hello
-index 557db03..263414f 100644
---- a/hello
-+++ b/hello
-@@ -1 +1,2 @@
- Hello World
-+It's a new day for git
-----
-
-i.e. the diff of the change we caused by adding another line to `hello`.
-
-In other words, `git-diff-files` always shows us the difference between
-what is recorded in the index, and what is currently in the working
-tree. That's very useful.
-
-A common shorthand for `git-diff-files -p` is to just write `git
-diff`, which will do the same thing.
-
-------------
-$ git diff
-diff --git a/hello b/hello
-index 557db03..263414f 100644
---- a/hello
-+++ b/hello
-@@ -1 +1,2 @@
- Hello World
-+It's a new day for git
-------------
-
-
-Committing git state
---------------------
-
-Now, we want to go to the next stage in git, which is to take the files
-that git knows about in the index, and commit them as a real tree. We do
-that in two phases: creating a 'tree' object, and committing that 'tree'
-object as a 'commit' object together with an explanation of what the
-tree was all about, along with information of how we came to that state.
-
-Creating a tree object is trivial, and is done with `git-write-tree`.
-There are no options or other input: git-write-tree will take the
-current index state, and write an object that describes that whole
-index. In other words, we're now tying together all the different
-filenames with their contents (and their permissions), and we're
-creating the equivalent of a git "directory" object:
-
-------------------------------------------------
-$ git-write-tree
-------------------------------------------------
-
-and this will just output the name of the resulting tree, in this case
-(if you have done exactly as I've described) it should be
-
-----------------
-8988da15d077d4829fc51d8544c097def6644dbb
-----------------
-
-which is another incomprehensible object name. Again, if you want to,
-you can use `git-cat-file -t 8988d\...` to see that this time the object
-is not a "blob" object, but a "tree" object (you can also use
-`git-cat-file` to actually output the raw object contents, but you'll see
-mainly a binary mess, so that's less interesting).
-
-However -- normally you'd never use `git-write-tree` on its own, because
-normally you always commit a tree into a commit object using the
-`git-commit-tree` command. In fact, it's easier to not actually use
-`git-write-tree` on its own at all, but to just pass its result in as an
-argument to `git-commit-tree`.
-
-`git-commit-tree` normally takes several arguments -- it wants to know
-what the 'parent' of a commit was, but since this is the first commit
-ever in this new repository, and it has no parents, we only need to pass in
-the object name of the tree. However, `git-commit-tree`
-also wants to get a commit message
-on its standard input, and it will write out the resulting object name for the
-commit to its standard output.
-
-And this is where we create the `.git/refs/heads/master` file
-which is pointed at by `HEAD`. This file is supposed to contain
-the reference to the top-of-tree of the master branch, and since
-that's exactly what `git-commit-tree` spits out, we can do this
-all with a sequence of simple shell commands:
-
-------------------------------------------------
-$ tree=$(git-write-tree)
-$ commit=$(echo 'Initial commit' | git-commit-tree $tree)
-$ git-update-ref HEAD $commit
-------------------------------------------------
-
-In this case this creates a totally new commit that is not related to
-anything else. Normally you do this only *once* for a project ever, and
-all later commits will be parented on top of an earlier commit.
-
-Again, normally you'd never actually do this by hand. There is a
-helpful script called `git commit` that will do all of this for you. So
-you could have just written `git commit`
-instead, and it would have done the above magic scripting for you.
-
-
-Making a change
----------------
-
-Remember how we did the `git-update-index` on file `hello` and then we
-changed `hello` afterward, and could compare the new state of `hello` with the
-state we saved in the index file? 
-
-Further, remember how I said that `git-write-tree` writes the contents
-of the *index* file to the tree, and thus what we just committed was in
-fact the *original* contents of the file `hello`, not the new ones. We did
-that on purpose, to show the difference between the index state, and the
-state in the working tree, and how they don't have to match, even
-when we commit things.
-
-As before, if we do `git-diff-files -p` in our git-tutorial project,
-we'll still see the same difference we saw last time: the index file
-hasn't changed by the act of committing anything. However, now that we
-have committed something, we can also learn to use a new command:
-`git-diff-index`.
-
-Unlike `git-diff-files`, which showed the difference between the index
-file and the working tree, `git-diff-index` shows the differences
-between a committed *tree* and either the index file or the working
-tree. In other words, `git-diff-index` wants a tree to be diffed
-against, and before we did the commit, we couldn't do that, because we
-didn't have anything to diff against. 
-
-But now we can do
-
-----------------
-$ git-diff-index -p HEAD
-----------------
-
-(where `-p` has the same meaning as it did in `git-diff-files`), and it
-will show us the same difference, but for a totally different reason. 
-Now we're comparing the working tree not against the index file,
-but against the tree we just wrote. It just so happens that those two
-are obviously the same, so we get the same result.
-
-Again, because this is a common operation, you can also just shorthand
-it with
-
-----------------
-$ git diff HEAD
-----------------
-
-which ends up doing the above for you.
-
-In other words, `git-diff-index` normally compares a tree against the
-working tree, but when given the `\--cached` flag, it is told to
-instead compare against just the index cache contents, and ignore the
-current working tree state entirely. Since we just wrote the index
-file to HEAD, doing `git-diff-index \--cached -p HEAD` should thus return
-an empty set of differences, and that's exactly what it does. 
-
-[NOTE]
-================
-`git-diff-index` really always uses the index for its
-comparisons, and saying that it compares a tree against the working
-tree is thus not strictly accurate. In particular, the list of
-files to compare (the "meta-data") *always* comes from the index file,
-regardless of whether the `\--cached` flag is used or not. The `\--cached`
-flag really only determines whether the file *contents* to be compared
-come from the working tree or not.
-
-This is not hard to understand, as soon as you realize that git simply
-never knows (or cares) about files that it is not told about
-explicitly. git will never go *looking* for files to compare, it
-expects you to tell it what the files are, and that's what the index
-is there for.
-================
-
-However, our next step is to commit the *change* we did, and again, to
-understand what's going on, keep in mind the difference between "working
-tree contents", "index file" and "committed tree". We have changes
-in the working tree that we want to commit, and we always have to
-work through the index file, so the first thing we need to do is to
-update the index cache:
-
-------------------------------------------------
-$ git-update-index hello
-------------------------------------------------
-
-(note how we didn't need the `\--add` flag this time, since git knew
-about the file already).
-
-Note what happens to the different `git-diff-\*` versions here. After
-we've updated `hello` in the index, `git-diff-files -p` now shows no
-differences, but `git-diff-index -p HEAD` still *does* show that the
-current state is different from the state we committed. In fact, now
-`git-diff-index` shows the same difference whether we use the `--cached`
-flag or not, since now the index is coherent with the working tree.
-
-Now, since we've updated `hello` in the index, we can commit the new
-version. We could do it by writing the tree by hand again, and
-committing the tree (this time we'd have to use the `-p HEAD` flag to
-tell commit that the HEAD was the *parent* of the new commit, and that
-this wasn't an initial commit any more), but you've done that once
-already, so let's just use the helpful script this time:
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-which starts an editor for you to write the commit message and tells you
-a bit about what you have done.
-
-Write whatever message you want, and all the lines that start with '#'
-will be pruned out, and the rest will be used as the commit message for
-the change. If you decide you don't want to commit anything after all at
-this point (you can continue to edit things and update the index), you
-can just leave an empty message. Otherwise `git commit` will commit
-the change for you.
-
-You've now made your first real git commit. And if you're interested in
-looking at what `git commit` really does, feel free to investigate:
-it's a few very simple shell scripts to generate the helpful (?) commit
-message headers, and a few one-liners that actually do the
-commit itself (`git-commit`).
-
-
-Inspecting Changes
-------------------
-
-While creating changes is useful, it's even more useful if you can tell
-later what changed. The most useful command for this is another of the
-`diff` family, namely `git-diff-tree`.
-
-`git-diff-tree` can be given two arbitrary trees, and it will tell you the
-differences between them. Perhaps even more commonly, though, you can
-give it just a single commit object, and it will figure out the parent
-of that commit itself, and show the difference directly. Thus, to get
-the same diff that we've already seen several times, we can now do
-
-----------------
-$ git-diff-tree -p HEAD
-----------------
-
-(again, `-p` means to show the difference as a human-readable patch),
-and it will show what the last commit (in `HEAD`) actually changed.
-
-[NOTE]
-============
-Here is an ASCII art by Jon Loeliger that illustrates how
-various diff-\* commands compare things.
-

-                      |    |
-                      |    |  diff-files

-                    | Directory |
-                    +-----------+
-============
-
-More interestingly, you can also give `git-diff-tree` the `--pretty` flag,
-which tells it to also show the commit message and author and date of the
-commit, and you can tell it to show a whole series of diffs.
-Alternatively, you can tell it to be "silent", and not show the diffs at
-all, but just show the actual commit message.
-
-In fact, together with the `git-rev-list` program (which generates a
-list of revisions), `git-diff-tree` ends up being a veritable fount of
-changes. A trivial (but very useful) script called `git-whatchanged` is
-included with git which does exactly this, and shows a log of recent
-activities.
-
-To see the whole history of our pitiful little git-tutorial project, you
-can do
-
-----------------
-$ git log
-----------------
-
-which shows just the log messages, or if we want to see the log together
-with the associated patches use the more complex (and much more
-powerful)
-
-----------------
-$ git-whatchanged -p --root
-----------------
-
-and you will see exactly what has changed in the repository over its
-short history. 
-
-[NOTE]
-The `\--root` flag is a flag to `git-diff-tree` to tell it to
-show the initial aka 'root' commit too. Normally you'd probably not
-want to see the initial import diff, but since the tutorial project
-was started from scratch and is so small, we use it to make the result
-a bit more interesting.
-
-With that, you should now be having some inkling of what git does, and
-can explore on your own.
-
-[NOTE]
-Most likely, you are not directly using the core
-git Plumbing commands, but using Porcelain like Cogito on top
-of it. Cogito works a bit differently and you usually do not
-have to run `git-update-index` yourself for changed files (you
-do tell underlying git about additions and removals via
-`cg-add` and `cg-rm` commands). Just before you make a commit
-with `cg-commit`, Cogito figures out which files you modified,
-and runs `git-update-index` on them for you.
-
-
-Tagging a version
------------------
-
-In git, there are two kinds of tags, a "light" one, and an "annotated tag".
-
-A "light" tag is technically nothing more than a branch, except we put
-it in the `.git/refs/tags/` subdirectory instead of calling it a `head`.
-So the simplest form of tag involves nothing more than
-
-------------------------------------------------
-$ git tag my-first-tag
-------------------------------------------------
-
-which just writes the current `HEAD` into the `.git/refs/tags/my-first-tag`
-file, after which point you can then use this symbolic name for that
-particular state. You can, for example, do
-
-----------------
-$ git diff my-first-tag
-----------------
-
-to diff your current state against that tag (which at this point will
-obviously be an empty diff, but if you continue to develop and commit
-stuff, you can use your tag as an "anchor-point" to see what has changed
-since you tagged it.
-
-An "annotated tag" is actually a real git object, and contains not only a
-pointer to the state you want to tag, but also a small tag name and
-message, along with optionally a PGP signature that says that yes,
-you really did
-that tag. You create these annotated tags with either the `-a` or
-`-s` flag to `git tag`:
-
-----------------
-$ git tag -s <tagname>
-----------------
-
-which will sign the current `HEAD` (but you can also give it another
-argument that specifies the thing to tag, i.e., you could have tagged the
-current `mybranch` point by using `git tag <tagname> mybranch`).
-
-You normally only do signed tags for major releases or things
-like that, while the light-weight tags are useful for any marking you
-want to do -- any time you decide that you want to remember a certain
-point, just create a private tag for it, and you have a nice symbolic
-name for the state at that point.
-
-
-Copying repositories
---------------------
-
-git repositories are normally totally self-sufficient and relocatable.
-Unlike CVS, for example, there is no separate notion of
-"repository" and "working tree". A git repository normally *is* the
-working tree, with the local git information hidden in the `.git`
-subdirectory. There is nothing else. What you see is what you got.
-
-[NOTE]
-You can tell git to split the git internal information from
-the directory that it tracks, but we'll ignore that for now: it's not
-how normal projects work, and it's really only meant for special uses.
-So the mental model of "the git information is always tied directly to
-the working tree that it describes" may not be technically 100%
-accurate, but it's a good model for all normal use.
-
-This has two implications: 
-
- - if you grow bored with the tutorial repository you created (or you've
-   made a mistake and want to start all over), you can just do simple
-+
-----------------
-$ rm -rf git-tutorial
-----------------
-+
-and it will be gone. There's no external repository, and there's no
-history outside the project you created.
-
- - if you want to move or duplicate a git repository, you can do so. There
-   is `git clone` command, but if all you want to do is just to
-   create a copy of your repository (with all the full history that
-   went along with it), you can do so with a regular
-   `cp -a git-tutorial new-git-tutorial`.
-+
-Note that when you've moved or copied a git repository, your git index
-file (which caches various information, notably some of the "stat"
-information for the files involved) will likely need to be refreshed.
-So after you do a `cp -a` to create a new copy, you'll want to do
-+
-----------------
-$ git-update-index --refresh
-----------------
-+
-in the new repository to make sure that the index file is up-to-date.
-
-Note that the second point is true even across machines. You can
-duplicate a remote git repository with *any* regular copy mechanism, be it
-`scp`, `rsync` or `wget`.
-
-When copying a remote repository, you'll want to at a minimum update the
-index cache when you do this, and especially with other peoples'
-repositories you often want to make sure that the index cache is in some
-known state (you don't know *what* they've done and not yet checked in),
-so usually you'll precede the `git-update-index` with a
-
-----------------
-$ git-read-tree --reset HEAD
-$ git-update-index --refresh
-----------------
-
-which will force a total index re-build from the tree pointed to by `HEAD`.
-It resets the index contents to `HEAD`, and then the `git-update-index`
-makes sure to match up all index entries with the checked-out files.
-If the original repository had uncommitted changes in its
-working tree, `git-update-index --refresh` notices them and
-tells you they need to be updated.
-
-The above can also be written as simply
-
-----------------
-$ git reset
-----------------
-
-and in fact a lot of the common git command combinations can be scripted
-with the `git xyz` interfaces.  You can learn things by just looking
-at what the various git scripts do.  For example, `git reset` is the
-above two lines implemented in `git-reset`, but some things like
-`git status` and `git commit` are slightly more complex scripts around
-the basic git commands.
-
-Many (most?) public remote repositories will not contain any of
-the checked out files or even an index file, and will *only* contain the
-actual core git files. Such a repository usually doesn't even have the
-`.git` subdirectory, but has all the git files directly in the
-repository. 
-
-To create your own local live copy of such a "raw" git repository, you'd
-first create your own subdirectory for the project, and then copy the
-raw repository contents into the `.git` directory. For example, to
-create your own copy of the git repository, you'd do the following
-
-----------------
-$ mkdir my-git
-$ cd my-git
-$ rsync -rL rsync://rsync.kernel.org/pub/scm/git/git.git/ .git
-----------------
-
-followed by 
-
-----------------
-$ git-read-tree HEAD
-----------------
-
-to populate the index. However, now you have populated the index, and
-you have all the git internal files, but you will notice that you don't
-actually have any of the working tree files to work on. To get
-those, you'd check them out with
-
-----------------
-$ git-checkout-index -u -a
-----------------
-
-where the `-u` flag means that you want the checkout to keep the index
-up-to-date (so that you don't have to refresh it afterward), and the
-`-a` flag means "check out all files" (if you have a stale copy or an
-older version of a checked out tree you may also need to add the `-f`
-flag first, to tell git-checkout-index to *force* overwriting of any old
-files). 
-
-Again, this can all be simplified with
-
-----------------
-$ git clone rsync://rsync.kernel.org/pub/scm/git/git.git/ my-git
-$ cd my-git
-$ git checkout
-----------------
-
-which will end up doing all of the above for you.
-
-You have now successfully copied somebody else's (mine) remote
-repository, and checked it out. 
-
-
-Creating a new branch
----------------------
-
-Branches in git are really nothing more than pointers into the git
-object database from within the `.git/refs/` subdirectory, and as we
-already discussed, the `HEAD` branch is nothing but a symlink to one of
-these object pointers. 
-
-You can at any time create a new branch by just picking an arbitrary
-point in the project history, and just writing the SHA1 name of that
-object into a file under `.git/refs/heads/`. You can use any filename you
-want (and indeed, subdirectories), but the convention is that the
-"normal" branch is called `master`. That's just a convention, though,
-and nothing enforces it. 
-
-To show that as an example, let's go back to the git-tutorial repository we
-used earlier, and create a branch in it. You do that by simply just
-saying that you want to check out a new branch:
-
-------------
-$ git checkout -b mybranch
-------------
-
-will create a new branch based at the current `HEAD` position, and switch
-to it. 
-
-[NOTE]
-================================================
-If you make the decision to start your new branch at some
-other point in the history than the current `HEAD`, you can do so by
-just telling `git checkout` what the base of the checkout would be.
-In other words, if you have an earlier tag or branch, you'd just do
-
-------------
-$ git checkout -b mybranch earlier-commit
-------------
-
-and it would create the new branch `mybranch` at the earlier commit,
-and check out the state at that time.
-================================================
-
-You can always just jump back to your original `master` branch by doing
-
-------------
-$ git checkout master
-------------
-
-(or any other branch-name, for that matter) and if you forget which
-branch you happen to be on, a simple
-
-------------
-$ cat .git/HEAD
-------------
-
-will tell you where it's pointing.  To get the list of branches
-you have, you can say
-
-------------
-$ git branch
-------------
-
-which is nothing more than a simple script around `ls .git/refs/heads`.
-There will be asterisk in front of the branch you are currently on.
-
-Sometimes you may wish to create a new branch _without_ actually
-checking it out and switching to it. If so, just use the command
-
-------------
-$ git branch <branchname> [startingpoint]
-------------
-
-which will simply _create_ the branch, but will not do anything further. 
-You can then later -- once you decide that you want to actually develop
-on that branch -- switch to that branch with a regular `git checkout`
-with the branchname as the argument.
-
-
-Merging two branches
---------------------
-
-One of the ideas of having a branch is that you do some (possibly
-experimental) work in it, and eventually merge it back to the main
-branch. So assuming you created the above `mybranch` that started out
-being the same as the original `master` branch, let's make sure we're in
-that branch, and do some work there.
-
-------------------------------------------------
-$ git checkout mybranch
-$ echo "Work, work, work" >>hello
-$ git commit -m 'Some work.' -i hello
-------------------------------------------------
-
-Here, we just added another line to `hello`, and we used a shorthand for
-doing both `git-update-index hello` and `git commit` by just giving the
-filename directly to `git commit`, with an `-i` flag (it tells
-git to 'include' that file in addition to what you have done to
-the index file so far when making the commit).  The `-m` flag is to give the
-commit log message from the command line.
-
-Now, to make it a bit more interesting, let's assume that somebody else
-does some work in the original branch, and simulate that by going back
-to the master branch, and editing the same file differently there:
-
-------------
-$ git checkout master
-------------
-
-Here, take a moment to look at the contents of `hello`, and notice how they
-don't contain the work we just did in `mybranch` -- because that work
-hasn't happened in the `master` branch at all. Then do
-
-------------
-$ echo "Play, play, play" >>hello
-$ echo "Lots of fun" >>example
-$ git commit -m 'Some fun.' -i hello example
-------------
-
-since the master branch is obviously in a much better mood.
-
-Now, you've got two branches, and you decide that you want to merge the
-work done. Before we do that, let's introduce a cool graphical tool that
-helps you view what's going on:
-
-----------------
-$ gitk --all
-----------------
-
-will show you graphically both of your branches (that's what the `\--all`
-means: normally it will just show you your current `HEAD`) and their
-histories. You can also see exactly how they came to be from a common
-source. 
-
-Anyway, let's exit `gitk` (`^Q` or the File menu), and decide that we want
-to merge the work we did on the `mybranch` branch into the `master`
-branch (which is currently our `HEAD` too). To do that, there's a nice
-script called `git merge`, which wants to know which branches you want
-to resolve and what the merge is all about:
-
-------------
-$ git merge "Merge work in mybranch" HEAD mybranch
-------------
-
-where the first argument is going to be used as the commit message if
-the merge can be resolved automatically.
-
-Now, in this case we've intentionally created a situation where the
-merge will need to be fixed up by hand, though, so git will do as much
-of it as it can automatically (which in this case is just merge the `example`
-file, which had no differences in the `mybranch` branch), and say:
-
-----------------
-	Auto-merging hello 
-	CONFLICT (content): Merge conflict in hello 
-	Automatic merge failed; fix up by hand
-----------------
-
-It tells you that it did an "Automatic merge", which
-failed due to conflicts in `hello`.
-
-Not to worry. It left the (trivial) conflict in `hello` in the same form you
-should already be well used to if you've ever used CVS, so let's just
-open `hello` in our editor (whatever that may be), and fix it up somehow.
-I'd suggest just making it so that `hello` contains all four lines:
-
-------------
-Hello World
-It's a new day for git
-Play, play, play
-Work, work, work
-------------
-
-and once you're happy with your manual merge, just do a
-
-------------
-$ git commit -i hello
-------------
-
-which will very loudly warn you that you're now committing a merge
-(which is correct, so never mind), and you can write a small merge
-message about your adventures in git-merge-land.
-
-After you're done, start up `gitk \--all` to see graphically what the
-history looks like. Notice that `mybranch` still exists, and you can
-switch to it, and continue to work with it if you want to. The
-`mybranch` branch will not contain the merge, but next time you merge it
-from the `master` branch, git will know how you merged it, so you'll not
-have to do _that_ merge again.
-
-Another useful tool, especially if you do not always work in X-Window
-environment, is `git show-branch`.
-
-------------------------------------------------
-$ git show-branch --topo-order master mybranch
-* [master] Merge work in mybranch
- ! [mybranch] Some work.
---
--  [master] Merge work in mybranch
-*+ [mybranch] Some work.
-------------------------------------------------
-
-The first two lines indicate that it is showing the two branches
-and the first line of the commit log message from their
-top-of-the-tree commits, you are currently on `master` branch
-(notice the asterisk `\*` character), and the first column for
-the later output lines is used to show commits contained in the
-`master` branch, and the second column for the `mybranch`
-branch. Three commits are shown along with their log messages.
-All of them have non blank characters in the first column (`*`
-shows an ordinary commit on the current branch, `.` is a merge commit), which
-means they are now part of the `master` branch. Only the "Some
-work" commit has the plus `+` character in the second column,
-because `mybranch` has not been merged to incorporate these
-commits from the master branch.  The string inside brackets
-before the commit log message is a short name you can use to
-name the commit.  In the above example, 'master' and 'mybranch'
-are branch heads.  'master~1' is the first parent of 'master'
-branch head.  Please see 'git-rev-parse' documentation if you
-see more complex cases.
-
-Now, let's pretend you are the one who did all the work in
-`mybranch`, and the fruit of your hard work has finally been merged
-to the `master` branch. Let's go back to `mybranch`, and run
-`git merge` to get the "upstream changes" back to your branch.
-
-------------
-$ git checkout mybranch
-$ git merge "Merge upstream changes." HEAD master
-------------
-
-This outputs something like this (the actual commit object names
-would be different)
-
-----------------
-Updating from ae3a2da... to a80b4aa....
-Fast forward
- example |    1 +
- hello   |    1 +
- 2 files changed, 2 insertions(+), 0 deletions(-)
-----------------
-
-Because your branch did not contain anything more than what are
-already merged into the `master` branch, the merge operation did
-not actually do a merge. Instead, it just updated the top of
-the tree of your branch to that of the `master` branch. This is
-often called 'fast forward' merge.
-
-You can run `gitk \--all` again to see how the commit ancestry
-looks like, or run `show-branch`, which tells you this.
-
-------------------------------------------------
-$ git show-branch master mybranch
-! [master] Merge work in mybranch
- * [mybranch] Merge work in mybranch
---
--- [master] Merge work in mybranch
-------------------------------------------------
-
-
-Merging external work
----------------------
-
-It's usually much more common that you merge with somebody else than
-merging with your own branches, so it's worth pointing out that git
-makes that very easy too, and in fact, it's not that different from
-doing a `git merge`. In fact, a remote merge ends up being nothing
-more than "fetch the work from a remote repository into a temporary tag"
-followed by a `git merge`.
-
-Fetching from a remote repository is done by, unsurprisingly,
-`git fetch`:
-
-----------------
-$ git fetch <remote-repository>
-----------------
-
-One of the following transports can be used to name the
-repository to download from:
-
-Rsync::
-	`rsync://remote.machine/path/to/repo.git/`
-+
-Rsync transport is usable for both uploading and downloading,
-but is completely unaware of what git does, and can produce
-unexpected results when you download from the public repository
-while the repository owner is uploading into it via `rsync`
-transport.  Most notably, it could update the files under
-`refs/` which holds the object name of the topmost commits
-before uploading the files in `objects/` -- the downloader would
-obtain head commit object name while that object itself is still
-not available in the repository.  For this reason, it is
-considered deprecated.
-
-SSH::
-	`remote.machine:/path/to/repo.git/` or
-+
-`ssh://remote.machine/path/to/repo.git/`
-+
-This transport can be used for both uploading and downloading,
-and requires you to have a log-in privilege over `ssh` to the
-remote machine.  It finds out the set of objects the other side
-lacks by exchanging the head commits both ends have and
-transfers (close to) minimum set of objects.  It is by far the
-most efficient way to exchange git objects between repositories.
-
-Local directory::
-	`/path/to/repo.git/`
-+
-This transport is the same as SSH transport but uses `sh` to run
-both ends on the local machine instead of running other end on
-the remote machine via `ssh`.
-
-git Native::
-	`git://remote.machine/path/to/repo.git/`
-+
-This transport was designed for anonymous downloading.  Like SSH
-transport, it finds out the set of objects the downstream side
-lacks and transfers (close to) minimum set of objects.
-
-HTTP(S)::
-	`http://remote.machine/path/to/repo.git/`
-+
-Downloader from http and https URL
-first obtains the topmost commit object name from the remote site
-by looking at the specified refname under `repo.git/refs/` directory,
-and then tries to obtain the
-commit object by downloading from `repo.git/objects/xx/xxx\...`
-using the object name of that commit object.  Then it reads the
-commit object to find out its parent commits and the associate
-tree object; it repeats this process until it gets all the
-necessary objects.  Because of this behavior, they are
-sometimes also called 'commit walkers'.
-+
-The 'commit walkers' are sometimes also called 'dumb
-transports', because they do not require any git aware smart
-server like git Native transport does.  Any stock HTTP server
-that does not even support directory index would suffice.  But
-you must prepare your repository with `git-update-server-info`
-to help dumb transport downloaders.
-+
-There are (confusingly enough) `git-ssh-fetch` and `git-ssh-upload`
-programs, which are 'commit walkers'; they outlived their
-usefulness when git Native and SSH transports were introduced,
-and not used by `git pull` or `git push` scripts.
-
-Once you fetch from the remote repository, you `merge` that
-with your current branch.
-
-However -- it's such a common thing to `fetch` and then
-immediately `merge`, that it's called `git pull`, and you can
-simply do
-
-----------------
-$ git pull <remote-repository>
-----------------
-
-and optionally give a branch-name for the remote end as a second
-argument.
-
-[NOTE]
-You could do without using any branches at all, by
-keeping as many local repositories as you would like to have
-branches, and merging between them with `git pull`, just like
-you merge between branches. The advantage of this approach is
-that it lets you keep a set of files for each `branch` checked
-out and you may find it easier to switch back and forth if you
-juggle multiple lines of development simultaneously. Of
-course, you will pay the price of more disk usage to hold
-multiple working trees, but disk space is cheap these days.
-
-It is likely that you will be pulling from the same remote
-repository from time to time. As a short hand, you can store
-the remote repository URL in the local repository's config file
-like this:
-
-------------------------------------------------
-$ git config remote.linus.url http://www.kernel.org/pub/scm/git/git.git/
-------------------------------------------------
-
-and use the "linus" keyword with `git pull` instead of the full URL.
-
-Examples.
-
-. `git pull linus`
-. `git pull linus tag v0.99.1`
-
-the above are equivalent to:
-
-. `git pull http://www.kernel.org/pub/scm/git/git.git/ HEAD`
-. `git pull http://www.kernel.org/pub/scm/git/git.git/ tag v0.99.1`
-
-
-How does the merge work?
-------------------------
-
-We said this tutorial shows what plumbing does to help you cope
-with the porcelain that isn't flushing, but we so far did not
-talk about how the merge really works.  If you are following
-this tutorial the first time, I'd suggest to skip to "Publishing
-your work" section and come back here later.
-
-OK, still with me?  To give us an example to look at, let's go
-back to the earlier repository with "hello" and "example" file,
-and bring ourselves back to the pre-merge state:
-
-------------
-$ git show-branch --more=3 master mybranch
-! [master] Merge work in mybranch
- * [mybranch] Merge work in mybranch
---
--- [master] Merge work in mybranch
-+* [master^2] Some work.
-+* [master^] Some fun.
-------------
-
-Remember, before running `git merge`, our `master` head was at
-"Some fun." commit, while our `mybranch` head was at "Some
-work." commit.
-
-------------
-$ git checkout mybranch
-$ git reset --hard master^2
-$ git checkout master
-$ git reset --hard master^
-------------
-
-After rewinding, the commit structure should look like this:
-
-------------
-$ git show-branch
-* [master] Some fun.
- ! [mybranch] Some work.
---
- + [mybranch] Some work.
-*  [master] Some fun.
-*+ [mybranch^] New day.
-------------
-
-Now we are ready to experiment with the merge by hand.
-
-`git merge` command, when merging two branches, uses 3-way merge
-algorithm.  First, it finds the common ancestor between them.
-The command it uses is `git-merge-base`:
-
-------------
-$ mb=$(git-merge-base HEAD mybranch)
-------------
-
-The command writes the commit object name of the common ancestor
-to the standard output, so we captured its output to a variable,
-because we will be using it in the next step.  BTW, the common
-ancestor commit is the "New day." commit in this case.  You can
-tell it by:
-
-------------
-$ git-name-rev $mb
-my-first-tag
-------------
-
-After finding out a common ancestor commit, the second step is
-this:
-
-------------
-$ git-read-tree -m -u $mb HEAD mybranch
-------------
-
-This is the same `git-read-tree` command we have already seen,
-but it takes three trees, unlike previous examples.  This reads
-the contents of each tree into different 'stage' in the index
-file (the first tree goes to stage 1, the second stage 2,
-etc.).  After reading three trees into three stages, the paths
-that are the same in all three stages are 'collapsed' into stage
-0.  Also paths that are the same in two of three stages are
-collapsed into stage 0, taking the SHA1 from either stage 2 or
-stage 3, whichever is different from stage 1 (i.e. only one side
-changed from the common ancestor).
-
-After 'collapsing' operation, paths that are different in three
-trees are left in non-zero stages.  At this point, you can
-inspect the index file with this command:
-
-------------
-$ git-ls-files --stage
-100644 7f8b141b65fdcee47321e399a2598a235a032422 0	example
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1	hello
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2	hello
-100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
-------------
-
-In our example of only two files, we did not have unchanged
-files so only 'example' resulted in collapsing, but in real-life
-large projects, only small number of files change in one commit,
-and this 'collapsing' tends to trivially merge most of the paths
-fairly quickly, leaving only a handful the real changes in non-zero
-stages.
-
-To look at only non-zero stages, use `\--unmerged` flag:
-
-------------
-$ git-ls-files --unmerged
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1	hello
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2	hello
-100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
-------------
-
-The next step of merging is to merge these three versions of the
-file, using 3-way merge.  This is done by giving
-`git-merge-one-file` command as one of the arguments to
-`git-merge-index` command:
-
-------------
-$ git-merge-index git-merge-one-file hello
-Auto-merging hello.
-merge: warning: conflicts during merge
-ERROR: Merge conflict in hello.
-fatal: merge program failed
-------------
-
-`git-merge-one-file` script is called with parameters to
-describe those three versions, and is responsible to leave the
-merge results in the working tree.
-It is a fairly straightforward shell script, and
-eventually calls `merge` program from RCS suite to perform a
-file-level 3-way merge.  In this case, `merge` detects
-conflicts, and the merge result with conflict marks is left in
-the working tree..  This can be seen if you run `ls-files
---stage` again at this point:
-
-------------
-$ git-ls-files --stage
-100644 7f8b141b65fdcee47321e399a2598a235a032422 0	example
-100644 263414f423d0e4d70dae8fe53fa34614ff3e2860 1	hello
-100644 06fa6a24256dc7e560efa5687fa84b51f0263c3a 2	hello
-100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
-------------
-
-This is the state of the index file and the working file after
-`git merge` returns control back to you, leaving the conflicting
-merge for you to resolve.  Notice that the path `hello` is still
-unmerged, and what you see with `git diff` at this point is
-differences since stage 2 (i.e. your version).
-
-
-Publishing your work
---------------------
-
-So, we can use somebody else's work from a remote repository, but
-how can *you* prepare a repository to let other people pull from
-it?
-
-Your do your real work in your working tree that has your
-primary repository hanging under it as its `.git` subdirectory.
-You *could* make that repository accessible remotely and ask
-people to pull from it, but in practice that is not the way
-things are usually done. A recommended way is to have a public
-repository, make it reachable by other people, and when the
-changes you made in your primary working tree are in good shape,
-update the public repository from it. This is often called
-'pushing'.
-
-[NOTE]
-This public repository could further be mirrored, and that is
-how git repositories at `kernel.org` are managed.
-
-Publishing the changes from your local (private) repository to
-your remote (public) repository requires a write privilege on
-the remote machine. You need to have an SSH account there to
-run a single command, `git-receive-pack`.
-
-First, you need to create an empty repository on the remote
-machine that will house your public repository. This empty
-repository will be populated and be kept up-to-date by pushing
-into it later. Obviously, this repository creation needs to be
-done only once.
-
-[NOTE]
-`git push` uses a pair of programs,
-`git-send-pack` on your local machine, and `git-receive-pack`
-on the remote machine. The communication between the two over
-the network internally uses an SSH connection.
-
-Your private repository's git directory is usually `.git`, but
-your public repository is often named after the project name,
-i.e. `<project>.git`. Let's create such a public repository for
-project `my-git`. After logging into the remote machine, create
-an empty directory:
-
-------------
-$ mkdir my-git.git
-------------
-
-Then, make that directory into a git repository by running
-`git init`, but this time, since its name is not the usual
-`.git`, we do things slightly differently:
-
-------------
-$ GIT_DIR=my-git.git git-init
-------------
-
-Make sure this directory is available for others you want your
-changes to be pulled by via the transport of your choice. Also
-you need to make sure that you have the `git-receive-pack`
-program on the `$PATH`.
-
-[NOTE]
-Many installations of sshd do not invoke your shell as the login
-shell when you directly run programs; what this means is that if
-your login shell is `bash`, only `.bashrc` is read and not
-`.bash_profile`. As a workaround, make sure `.bashrc` sets up
-`$PATH` so that you can run `git-receive-pack` program.
-
-[NOTE]
-If you plan to publish this repository to be accessed over http,
-you should do `chmod +x my-git.git/hooks/post-update` at this
-point.  This makes sure that every time you push into this
-repository, `git-update-server-info` is run.
-
-Your "public repository" is now ready to accept your changes.
-Come back to the machine you have your private repository. From
-there, run this command:
-
-------------
-$ git push <public-host>:/path/to/my-git.git master
-------------
-
-This synchronizes your public repository to match the named
-branch head (i.e. `master` in this case) and objects reachable
-from them in your current repository.
-
-As a real example, this is how I update my public git
-repository. Kernel.org mirror network takes care of the
-propagation to other publicly visible machines:
-
-------------
-$ git push master.kernel.org:/pub/scm/git/git.git/ 
-------------
-
-
-Packing your repository
------------------------
-
-Earlier, we saw that one file under `.git/objects/??/` directory
-is stored for each git object you create. This representation
-is efficient to create atomically and safely, but
-not so convenient to transport over the network. Since git objects are
-immutable once they are created, there is a way to optimize the
-storage by "packing them together". The command
-
-------------
-$ git repack
-------------
-
-will do it for you. If you followed the tutorial examples, you
-would have accumulated about 17 objects in `.git/objects/??/`
-directories by now. `git repack` tells you how many objects it
-packed, and stores the packed file in `.git/objects/pack`
-directory.
-
-[NOTE]
-You will see two files, `pack-\*.pack` and `pack-\*.idx`,
-in `.git/objects/pack` directory. They are closely related to
-each other, and if you ever copy them by hand to a different
-repository for whatever reason, you should make sure you copy
-them together. The former holds all the data from the objects
-in the pack, and the latter holds the index for random
-access.
-
-If you are paranoid, running `git-verify-pack` command would
-detect if you have a corrupt pack, but do not worry too much.
-Our programs are always perfect ;-).
-
-Once you have packed objects, you do not need to leave the
-unpacked objects that are contained in the pack file anymore.
-
-------------
-$ git prune-packed
-------------
-
-would remove them for you.
-
-You can try running `find .git/objects -type f` before and after
-you run `git prune-packed` if you are curious.  Also `git
-count-objects` would tell you how many unpacked objects are in
-your repository and how much space they are consuming.
-
-[NOTE]
-`git pull` is slightly cumbersome for HTTP transport, as a
-packed repository may contain relatively few objects in a
-relatively large pack. If you expect many HTTP pulls from your
-public repository you might want to repack & prune often, or
-never.
-
-If you run `git repack` again at this point, it will say
-"Nothing to pack". Once you continue your development and
-accumulate the changes, running `git repack` again will create a
-new pack, that contains objects created since you packed your
-repository the last time. We recommend that you pack your project
-soon after the initial import (unless you are starting your
-project from scratch), and then run `git repack` every once in a
-while, depending on how active your project is.
-
-When a repository is synchronized via `git push` and `git pull`
-objects packed in the source repository are usually stored
-unpacked in the destination, unless rsync transport is used.
-While this allows you to use different packing strategies on
-both ends, it also means you may need to repack both
-repositories every once in a while.
-
-
-Working with Others
--------------------
-
-Although git is a truly distributed system, it is often
-convenient to organize your project with an informal hierarchy
-of developers. Linux kernel development is run this way. There
-is a nice illustration (page 17, "Merges to Mainline") in
-link:http://tinyurl.com/a2jdg[Randy Dunlap's presentation].
-
-It should be stressed that this hierarchy is purely *informal*.
-There is nothing fundamental in git that enforces the "chain of
-patch flow" this hierarchy implies. You do not have to pull
-from only one remote repository.
-
-A recommended workflow for a "project lead" goes like this:
-
-1. Prepare your primary repository on your local machine. Your
-   work is done there.
-
-2. Prepare a public repository accessible to others.
-+
-If other people are pulling from your repository over dumb
-transport protocols (HTTP), you need to keep this repository
-'dumb transport friendly'.  After `git init`,
-`$GIT_DIR/hooks/post-update` copied from the standard templates
-would contain a call to `git-update-server-info` but the
-`post-update` hook itself is disabled by default -- enable it
-with `chmod +x post-update`.  This makes sure `git-update-server-info`
-keeps the necessary files up-to-date.
-
-3. Push into the public repository from your primary
-   repository.
-
-4. `git repack` the public repository. This establishes a big
-   pack that contains the initial set of objects as the
-   baseline, and possibly `git prune` if the transport
-   used for pulling from your repository supports packed
-   repositories.
-
-5. Keep working in your primary repository. Your changes
-   include modifications of your own, patches you receive via
-   e-mails, and merges resulting from pulling the "public"
-   repositories of your "subsystem maintainers".
-+
-You can repack this private repository whenever you feel like.
-
-6. Push your changes to the public repository, and announce it
-   to the public.
-
-7. Every once in a while, "git repack" the public repository.
-   Go back to step 5. and continue working.
-
-
-A recommended work cycle for a "subsystem maintainer" who works
-on that project and has an own "public repository" goes like this:
-
-1. Prepare your work repository, by `git clone` the public
-   repository of the "project lead". The URL used for the
-   initial cloning is stored in the remote.origin.url
-   configuration variable.
-
-2. Prepare a public repository accessible to others, just like
-   the "project lead" person does.
-
-3. Copy over the packed files from "project lead" public
-   repository to your public repository, unless the "project
-   lead" repository lives on the same machine as yours.  In the
-   latter case, you can use `objects/info/alternates` file to
-   point at the repository you are borrowing from.
-
-4. Push into the public repository from your primary
-   repository. Run `git repack`, and possibly `git prune` if the
-   transport used for pulling from your repository supports
-   packed repositories.
-
-5. Keep working in your primary repository. Your changes
-   include modifications of your own, patches you receive via
-   e-mails, and merges resulting from pulling the "public"
-   repositories of your "project lead" and possibly your
-   "sub-subsystem maintainers".
-+
-You can repack this private repository whenever you feel
-like.
-
-6. Push your changes to your public repository, and ask your
-   "project lead" and possibly your "sub-subsystem
-   maintainers" to pull from it.
-
-7. Every once in a while, `git repack` the public repository.
-   Go back to step 5. and continue working.
-
-
-A recommended work cycle for an "individual developer" who does
-not have a "public" repository is somewhat different. It goes
-like this:
-
-1. Prepare your work repository, by `git clone` the public
-   repository of the "project lead" (or a "subsystem
-   maintainer", if you work on a subsystem). The URL used for
-   the initial cloning is stored in the remote.origin.url
-   configuration variable.
-
-2. Do your work in your repository on 'master' branch.
-
-3. Run `git fetch origin` from the public repository of your
-   upstream every once in a while. This does only the first
-   half of `git pull` but does not merge. The head of the
-   public repository is stored in `.git/refs/remotes/origin/master`.
-
-4. Use `git cherry origin` to see which ones of your patches
-   were accepted, and/or use `git rebase origin` to port your
-   unmerged changes forward to the updated upstream.
-
-5. Use `git format-patch origin` to prepare patches for e-mail
-   submission to your upstream and send it out. Go back to
-   step 2. and continue.

-Working with Others, Shared Repository Style
---------------------------------------------
-
-If you are coming from CVS background, the style of cooperation
-suggested in the previous section may be new to you. You do not
-have to worry. git supports "shared public repository" style of
-cooperation you are probably more familiar with as well.
-
-See link:cvs-migration.html[git for CVS users] for the details.
-
-Bundling your work together
----------------------------
-
-It is likely that you will be working on more than one thing at
-a time.  It is easy to manage those more-or-less independent tasks
-using branches with git.
-
-We have already seen how branches work previously,
-with "fun and work" example using two branches.  The idea is the
-same if there are more than two branches.  Let's say you started
-out from "master" head, and have some new code in the "master"
-branch, and two independent fixes in the "commit-fix" and
-"diff-fix" branches:
-
-------------
-$ git show-branch
-! [commit-fix] Fix commit message normalization.
- ! [diff-fix] Fix rename detection.
-  * [master] Release candidate #1
----
- +  [diff-fix] Fix rename detection.
- +  [diff-fix~1] Better common substring algorithm.
-+   [commit-fix] Fix commit message normalization.
-  * [master] Release candidate #1
-++* [diff-fix~2] Pretty-print messages.
-------------
-
-Both fixes are tested well, and at this point, you want to merge
-in both of them.  You could merge in 'diff-fix' first and then
-'commit-fix' next, like this:
-
-------------
-$ git merge 'Merge fix in diff-fix' master diff-fix
-$ git merge 'Merge fix in commit-fix' master commit-fix
-------------
-
-Which would result in:
-
-------------
-$ git show-branch
-! [commit-fix] Fix commit message normalization.
- ! [diff-fix] Fix rename detection.
-  * [master] Merge fix in commit-fix
----
-  - [master] Merge fix in commit-fix
-+ * [commit-fix] Fix commit message normalization.
-  - [master~1] Merge fix in diff-fix
- +* [diff-fix] Fix rename detection.
- +* [diff-fix~1] Better common substring algorithm.
-  * [master~2] Release candidate #1
-++* [master~3] Pretty-print messages.
-------------
-
-However, there is no particular reason to merge in one branch
-first and the other next, when what you have are a set of truly
-independent changes (if the order mattered, then they are not
-independent by definition).  You could instead merge those two
-branches into the current branch at once.  First let's undo what
-we just did and start over.  We would want to get the master
-branch before these two merges by resetting it to 'master~2':
-
-------------
-$ git reset --hard master~2
-------------
-
-You can make sure 'git show-branch' matches the state before
-those two 'git merge' you just did.  Then, instead of running
-two 'git merge' commands in a row, you would merge these two
-branch heads (this is known as 'making an Octopus'):
-
-------------
-$ git merge commit-fix diff-fix
-$ git show-branch
-! [commit-fix] Fix commit message normalization.
- ! [diff-fix] Fix rename detection.
-  * [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
----
-  - [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
-+ * [commit-fix] Fix commit message normalization.
- +* [diff-fix] Fix rename detection.
- +* [diff-fix~1] Better common substring algorithm.
-  * [master~1] Release candidate #1
-++* [master~2] Pretty-print messages.
-------------
-
-Note that you should not do Octopus because you can.  An octopus
-is a valid thing to do and often makes it easier to view the
-commit history if you are merging more than two independent
-changes at the same time.  However, if you have merge conflicts
-with any of the branches you are merging in and need to hand
-resolve, that is an indication that the development happened in
-those branches were not independent after all, and you should
-merge two at a time, documenting how you resolved the conflicts,
-and the reason why you preferred changes made in one side over
-the other.  Otherwise it would make the project history harder
-to follow, not easier.

-git for CVS users
-=================
-
-Git differs from CVS in that every working tree contains a repository with
-a full copy of the project history, and no repository is inherently more
-important than any other.  However, you can emulate the CVS model by
-designating a single shared repository which people can synchronize with;
-this document explains how to do that.
-
-Some basic familiarity with git is required.  This
-link:tutorial.html[tutorial introduction to git] should be sufficient.
-
-Developing against a shared repository
---------------------------------------
-
-Suppose a shared repository is set up in /pub/repo.git on the host
-foo.com.  Then as an individual committer you can clone the shared
-repository over ssh with:
-
-------------------------------------------------
-$ git clone foo.com:/pub/repo.git/ my-project
-$ cd my-project
-------------------------------------------------
-
-and hack away.  The equivalent of `cvs update` is
-
-------------------------------------------------
-$ git pull origin
-------------------------------------------------
-
-which merges in any work that others might have done since the clone
-operation.  If there are uncommitted changes in your working tree, commit
-them first before running git pull.
-
-[NOTE]
-================================
-The `pull` command knows where to get updates from because of certain
-configuration variables that were set by the first `git clone`
-command; see `git config -l` and the gitlink:git-config[1] man
-page for details.
-================================
-
-You can update the shared repository with your changes by first committing
-your changes, and then using the gitlink:git-push[1] command:
-
-------------------------------------------------
-$ git push origin master
-------------------------------------------------
-
-to "push" those commits to the shared repository.  If someone else has
-updated the repository more recently, `git push`, like `cvs commit`, will
-complain, in which case you must pull any changes before attempting the
-push again.
-
-In the `git push` command above we specify the name of the remote branch
-to update (`master`).  If we leave that out, `git push` tries to update
-any branches in the remote repository that have the same name as a branch
-in the local repository.  So the last `push` can be done with either of:
-
-------------
-$ git push origin
-$ git push foo.com:/pub/project.git/
-------------
-
-as long as the shared repository does not have any branches
-other than `master`.
-
-Setting Up a Shared Repository
-------------------------------
-
-We assume you have already created a git repository for your project,
-possibly created from scratch or from a tarball (see the
-link:tutorial.html[tutorial]), or imported from an already existing CVS
-repository (see the next section).
-
-Assume your existing repo is at /home/alice/myproject.  Create a new "bare"
-repository (a repository without a working tree) and fetch your project into
-it:
-
-------------------------------------------------
-$ mkdir /pub/my-repo.git
-$ cd /pub/my-repo.git
-$ git --bare init --shared
-$ git --bare fetch /home/alice/myproject master:master
-------------------------------------------------
-
-Next, give every team member read/write access to this repository.  One
-easy way to do this is to give all the team members ssh access to the
-machine where the repository is hosted.  If you don't want to give them a
-full shell on the machine, there is a restricted shell which only allows
-users to do git pushes and pulls; see gitlink:git-shell[1].
-
-Put all the committers in the same group, and make the repository
-writable by that group:
-
-------------------------------------------------
-$ chgrp -R $group /pub/my-repo.git
-------------------------------------------------
-
-Make sure committers have a umask of at most 027, so that the directories
-they create are writable and searchable by other group members.
-
-Importing a CVS archive
------------------------
-
-First, install version 2.1 or higher of cvsps from
-link:http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
-sure it is in your path.  Then cd to a checked out CVS working directory
-of the project you are interested in and run gitlink:git-cvsimport[1]:
-
--------------------------------------------
-$ git cvsimport -C <destination> <module>
--------------------------------------------
-
-This puts a git archive of the named CVS module in the directory
-<destination>, which will be created if necessary.
-
-The import checks out from CVS every revision of every file.  Reportedly
-cvsimport can average some twenty revisions per second, so for a
-medium-sized project this should not take more than a couple of minutes.
-Larger projects or remote repositories may take longer.
-
-The main trunk is stored in the git branch named `origin`, and additional
-CVS branches are stored in git branches with the same names.  The most
-recent version of the main trunk is also left checked out on the `master`
-branch, so you can start adding your own changes right away.
-
-The import is incremental, so if you call it again next month it will
-fetch any CVS updates that have been made in the meantime.  For this to
-work, you must not modify the imported branches; instead, create new
-branches for your own changes, and merge in the imported branches as
-necessary.
-
-Advanced Shared Repository Management
--------------------------------------
-
-Git allows you to specify scripts called "hooks" to be run at certain
-points.  You can use these, for example, to send all commits to the shared
-repository to a mailing list.  See link:hooks.html[Hooks used by git].
-
-You can enforce finer grained permissions using update hooks.  See
-link:howto/update-hook-example.txt[Controlling access to branches using
-update hooks].
-
-Providing CVS Access to a git Repository
-----------------------------------------
-
-It is also possible to provide true CVS access to a git repository, so
-that developers can still use CVS; see gitlink:git-cvsserver[1] for
-details.
-
-Alternative Development Models
-------------------------------
-
-CVS users are accustomed to giving a group of developers commit access to
-a common repository.  As we've seen, this is also possible with git.
-However, the distributed nature of git allows other development models,
-and you may want to first consider whether one of them might be a better
-fit for your project.
-
-For example, you can choose a single person to maintain the project's
-primary public repository.  Other developers then clone this repository
-and each work in their own clone.  When they have a series of changes that
-they're happy with, they ask the maintainer to pull from the branch
-containing the changes.  The maintainer reviews their changes and pulls
-them into the primary repository, which other developers pull from as
-necessary to stay coordinated.  The Linux kernel and other projects use
-variants of this model.
-
-With a small group, developers may just pull changes from each other's
-repositories without the need for a central maintainer.

+DATE FORMATS
+------------
+
+The GIT_AUTHOR_DATE, GIT_COMMITTER_DATE environment variables
+ifdef::git-commit[]
+and the `--date` option
+endif::git-commit[]
+support the following date formats:
+
+Git internal format::
+	It is `<unix timestamp> <time zone offset>`, where `<unix
+	timestamp>` is the number of seconds since the UNIX epoch.
+	`<time zone offset>` is a positive or negative offset from UTC.
+	For example CET (which is 2 hours ahead UTC) is `+0200`.
+
+RFC 2822::
+	The standard email format as described by RFC 2822, for example
+	`Thu, 07 Apr 2005 22:13:13 +0200`.
+
+ISO 8601::
+	Time and date specified by the ISO 8601 standard, for example
+	`2005-04-07T22:13:13`. The parser accepts a space instead of the
+	`T` character as well.
++
+NOTE: In addition, the date part is accepted in the following formats:
+`YYYY.MM.DD`, `MM/DD/YYYY` and `DD.MM.YYYY`.

+diff.autoRefreshIndex::
+	When using 'git diff' to compare with work tree
+	files, do not consider stat-only change as changed.
+	Instead, silently run `git update-index --refresh` to
+	update the cached stat information for paths whose
+	contents in the work tree match the contents in the
+	index.  This option defaults to true.  Note that this
+	affects only 'git diff' Porcelain, and not lower level
+	'diff' commands such as 'git diff-files'.
+
+diff.dirstat::
+	A comma separated list of `--dirstat` parameters specifying the
+	default behavior of the `--dirstat` option to linkgit:git-diff[1]`
+	and friends. The defaults can be overridden on the command line
+	(using `--dirstat=<param1,param2,...>`). The fallback defaults
+	(when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
+	The following parameters are available:
++
+--
+`changes`;;
+	Compute the dirstat numbers by counting the lines that have been
+	removed from the source, or added to the destination. This ignores
+	the amount of pure code movements within a file.  In other words,
+	rearranging lines in a file is not counted as much as other changes.
+	This is the default behavior when no parameter is given.
+`lines`;;
+	Compute the dirstat numbers by doing the regular line-based diff
+	analysis, and summing the removed/added line counts. (For binary
+	files, count 64-byte chunks instead, since binary files have no
+	natural concept of lines). This is a more expensive `--dirstat`
+	behavior than the `changes` behavior, but it does count rearranged
+	lines within a file as much as other changes. The resulting output
+	is consistent with what you get from the other `--*stat` options.
+`files`;;
+	Compute the dirstat numbers by counting the number of files changed.
+	Each changed file counts equally in the dirstat analysis. This is
+	the computationally cheapest `--dirstat` behavior, since it does
+	not have to look at the file contents at all.
+`cumulative`;;
+	Count changes in a child directory for the parent directory as well.
+	Note that when using `cumulative`, the sum of the percentages
+	reported may exceed 100%. The default (non-cumulative) behavior can
+	be specified with the `noncumulative` parameter.
+<limit>;;
+	An integer parameter specifies a cut-off percent (3% by default).
+	Directories contributing less than this percentage of the changes
+	are not shown in the output.
+--
++
+Example: The following will count changed files, while ignoring
+directories with less than 10% of the total amount of changed files,
+and accumulating child directory counts in the parent directories:
+`files,10,cumulative`.
+
+diff.statGraphWidth::
+	Limit the width of the graph part in --stat output. If set, applies
+	to all commands generating --stat output except format-patch.
+
+diff.context::
+	Generate diffs with <n> lines of context instead of the default
+	of 3. This value is overridden by the -U option.
+
+diff.external::
+	If this config variable is set, diff generation is not
+	performed using the internal diff machinery, but using the
+	given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
+	environment variable.  The command is called with parameters
+	as described under "git Diffs" in linkgit:git[1].  Note: if
+	you want to use an external diff program only on a subset of
+	your files, you	might want to use linkgit:gitattributes[5] instead.
+
+diff.ignoreSubmodules::
+	Sets the default value of --ignore-submodules. Note that this
+	affects only 'git diff' Porcelain, and not lower level 'diff'
+	commands such as 'git diff-files'. 'git checkout' also honors
+	this setting when reporting uncommitted changes. Setting it to
+	'all' disables the submodule summary normally shown by 'git commit'
+	and 'git status' when 'status.submoduleSummary' is set unless it is
+	overridden by using the --ignore-submodules command-line option.
+	The 'git submodule' commands are not affected by this setting.
+
+diff.mnemonicPrefix::
+	If set, 'git diff' uses a prefix pair that is different from the
+	standard "a/" and "b/" depending on what is being compared.  When
+	this configuration is in effect, reverse diff output also swaps
+	the order of the prefixes:
+`git diff`;;
+	compares the (i)ndex and the (w)ork tree;
+`git diff HEAD`;;
+	 compares a (c)ommit and the (w)ork tree;
+`git diff --cached`;;
+	compares a (c)ommit and the (i)ndex;
+`git diff HEAD:file1 file2`;;
+	compares an (o)bject and a (w)ork tree entity;
+`git diff --no-index a b`;;
+	compares two non-git things (1) and (2).
+
+diff.noprefix::
+	If set, 'git diff' does not show any source or destination prefix.
+
+diff.orderFile::
+	File indicating how to order files within a diff, using
+	one shell glob pattern per line.
+	Can be overridden by the '-O' option to linkgit:git-diff[1].
+
+diff.renameLimit::
+	The number of files to consider when performing the copy/rename
+	detection; equivalent to the 'git diff' option '-l'.
+
+diff.renames::
+	Tells Git to detect renames.  If set to any boolean value, it
+	will enable basic rename detection.  If set to "copies" or
+	"copy", it will detect copies, as well.
+
+diff.suppressBlankEmpty::
+	A boolean to inhibit the standard behavior of printing a space
+	before each empty output line. Defaults to false.
+
+diff.submodule::
+	Specify the format in which differences in submodules are
+	shown.  The "log" format lists the commits in the range like
+	linkgit:git-submodule[1] `summary` does.  The "short" format
+	format just shows the names of the commits at the beginning
+	and end of the range.  Defaults to short.
+
+diff.wordRegex::
+	A POSIX Extended Regular Expression used to determine what is a "word"
+	when performing word-by-word difference calculations.  Character
+	sequences that match the regular expression are "words", all other
+	characters are *ignorable* whitespace.
+
+diff.<driver>.command::
+	The custom diff driver command.  See linkgit:gitattributes[5]
+	for details.
+
+diff.<driver>.xfuncname::
+	The regular expression that the diff driver should use to

+diff.<driver>.binary::
+	Set this option to true to make the diff driver treat files as
+	binary.  See linkgit:gitattributes[5] for details.
+
+diff.<driver>.textconv::
+	The command that the diff driver should call to generate the

+"git-diff-tree", "git-diff-files" and "git-diff --raw"
+can take '-c' or '--cc' option
+to generate diff output also for merge commits.  The output differs
+from the format described above in the following way:
+
+. there is a colon for each parent
+. there are more "src" modes and "src" sha1
+. status is concatenated status characters for each parent
+. no optional "score" number
+. single path, only for "dst"
+
+Example:
+
+------------------------------------------------
+::100644 100644 100644 fabadb8... cc95eb0... 4866510... MM	describe.c
+------------------------------------------------
+
+Note that 'combined diff' lists only files which were modified from
+all parents.
+
+
+include::diff-generate-patch.txt[]
+
+
+other diff formats
+------------------
+
+The `--summary` option describes newly added, deleted, renamed and
+copied files.  The `--stat` option adds diffstat(1) graph to the
+output.  These options can be combined with other options, such as
+`-p`, and are meant for human consumption.
+
+When showing a change that involves a rename or a copy, `--stat` output
+formats the pathnames compactly by combining common prefix and suffix of
+the pathnames.  For example, a change that moves `arch/i386/Makefile` to
+`arch/x86/Makefile` while modifying 4 lines will be shown like this:
+
+------------------------------------
+arch/{i386 => x86}/Makefile    |   4 +--
+------------------------------------
+
+The `--numstat` option gives the diffstat(1) information but is designed
+for easier machine consumption.  An entry in `--numstat` output looks
+like this:
+
+----------------------------------------
+1	2	README
+3	1	arch/{i386 => x86}/Makefile
+----------------------------------------
+
+That is, from left to right:
+
+. the number of added lines;
+. a tab;
+. the number of deleted lines;
+. a tab;
+. pathname (possibly with rename/copy information);
+. a newline.
+
+When `-z` output option is in effect, the output is formatted this way:
+
+----------------------------------------
+1	2	README NUL
+3	1	NUL arch/i386/Makefile NUL arch/x86/Makefile NUL
+----------------------------------------
+
+That is:
 
-Generating patches with -p
---------------------------
-
-When "git-diff-index", "git-diff-tree", or "git-diff-files" are run
-with a '-p' option, they do not produce the output described above;
-instead they produce a patch file.  You can customize the creation
-of such patches via the GIT_EXTERNAL_DIFF and the GIT_DIFF_OPTS
-environment variables.
-
-What the -p option produces is slightly different from the traditional
-diff format.
-
-1.   It is preceded with a "git diff" header, that looks like
-     this:
-
-       diff --git a/file1 b/file2
-+
-The `a/` and `b/` filenames are the same unless rename/copy is
-involved.  Especially, even for a creation or a deletion,
-`/dev/null` is _not_ used in place of `a/` or `b/` filenames.
-+
-When rename/copy is involved, `file1` and `file2` show the
-name of the source file of the rename/copy and the name of
-the file that rename/copy produces, respectively.
-
-2.   It is followed by one or more extended header lines:
-
-       old mode <mode>
-       new mode <mode>
-       deleted file mode <mode>
-       new file mode <mode>
-       copy from <path>
-       copy to <path>
-       rename from <path>
-       rename to <path>
-       similarity index <number>
-       dissimilarity index <number>
-       index <hash>..<hash> <mode>
-
-3.  TAB, LF, double quote and backslash characters in pathnames
-    are represented as `\t`, `\n`, `\"` and `\\`, respectively.
-    If there is need for such substitution then the whole
-    pathname is put in double quotes.
-
-
-combined diff format
---------------------
-
-git-diff-tree and git-diff-files can take '-c' or '--cc' option
-to produce 'combined diff', which looks like this:
-
-------------

-1.   It is preceded with a "git diff" header, that looks like

-
-       diff --combined file
-+
-or like this (when '--cc' option is used):
-
-       diff --c file
-
-2.   It is followed by one or more extended header lines
-     (this example shows a merge with two parents):
-
-       index <hash>,<hash>..<hash>
-       mode <mode>,<mode>..<mode>
-       new file mode <mode>
-       deleted file mode <mode>,<mode>
-+
-The `mode <mode>,<mode>..<mode>` line appears only if at least one of
-the <mode> is different from the rest. Extended headers with
-information about detected contents movement (renames and
-copying detection) are designed to work with diff of two
-<tree-ish> and are not used by combined diff format.
-
-3.   It is followed by two-line from-file/to-file header
-
-       --- a/file
-       +++ b/file
-+
-Similar to two-line header for traditional 'unified' diff
-format, `/dev/null` is used to signal created or deleted
-files.
-
-4.   Chunk header format is modified to prevent people from
-     accidentally feeding it to `patch -p1`. Combined diff format
-     was created for review of merge commit changes, and was not
-     meant for apply. The change is similar to the change in the
-     extended 'index' header:
-
-       @@@ <from-file-range> <from-file-range> <to-file-range> @@@
-+
-There are (number of parents + 1) `@` characters in the chunk
-header for combined diff format.
-
-Unlike the traditional 'unified' diff format, which shows two
-files A and B with a single column that has `-` (minus --
-appears in A but removed in B), `+` (plus -- missing in A but
-added to B), or `" "` (space -- unchanged) prefix, this format
-compares two or more files file1, file2,... with one file X, and
-shows how X differs from each of fileN.  One column for each of
-fileN is prepended to the output line to note how X's line is
-different from it.
-
-A `-` character in the column N means that the line appears in
-fileN but it does not appear in the result.  A `+` character
-in the column N means that the line appears in the last file,
-and fileN does not have that line (in other words, the line was
-added, from the point of view of that parent).
-
-In the above example output, the function signature was changed
-from both files (hence two `-` removals from both file1 and
-file2, plus `++` to mean one line that was added does not appear
-in either file1 nor file2).  Also two other lines are the same
-from file1 but do not appear in file2 (hence prefixed with ` +`).
-
-When shown by `git diff-tree -c`, it compares the parents of a
-merge commit with the merge result (i.e. file1..fileN are the
-parents).  When shown by `git diff-files -c`, it compares the
-two unresolved merge parents with the working tree file
-(i.e. file1 is stage 2 aka "our version", file2 is stage 3 aka
-"their version").

+Generating patches with -p
+--------------------------
+
+When "git-diff-index", "git-diff-tree", or "git-diff-files" are run
+with a '-p' option, "git diff" without the '--raw' option, or
+"git log" with the "-p" option, they
+do not produce the output described above; instead they produce a
+patch file.  You can customize the creation of such patches via the
+GIT_EXTERNAL_DIFF and the GIT_DIFF_OPTS environment variables.
+
+What the -p option produces is slightly different from the traditional
+diff format:
+
+1.   It is preceded with a "git diff" header that looks like this:
+
+       diff --git a/file1 b/file2
++
+The `a/` and `b/` filenames are the same unless rename/copy is
+involved.  Especially, even for a creation or a deletion,
+`/dev/null` is _not_ used in place of the `a/` or `b/` filenames.
++
+When rename/copy is involved, `file1` and `file2` show the
+name of the source file of the rename/copy and the name of
+the file that rename/copy produces, respectively.
+
+2.   It is followed by one or more extended header lines:
+
+       old mode <mode>
+       new mode <mode>
+       deleted file mode <mode>
+       new file mode <mode>
+       copy from <path>
+       copy to <path>
+       rename from <path>
+       rename to <path>
+       similarity index <number>
+       dissimilarity index <number>
+       index <hash>..<hash> <mode>
++
+File modes are printed as 6-digit octal numbers including the file type
+and file permission bits.
++
+Path names in extended headers do not include the `a/` and `b/` prefixes.
++
+The similarity index is the percentage of unchanged lines, and
+the dissimilarity index is the percentage of changed lines.  It
+is a rounded down integer, followed by a percent sign.  The
+similarity index value of 100% is thus reserved for two equal
+files, while 100% dissimilarity means that no line from the old
+file made it into the new one.
++
+The index line includes the SHA-1 checksum before and after the change.
+The <mode> is included if the file mode does not change; otherwise,
+separate lines indicate the old and the new mode.
+
+3.  TAB, LF, double quote and backslash characters in pathnames
+    are represented as `\t`, `\n`, `\"` and `\\`, respectively.
+    If there is need for such substitution then the whole
+    pathname is put in double quotes.
+
+4.  All the `file1` files in the output refer to files before the
+    commit, and all the `file2` files refer to files after the commit.
+    It is incorrect to apply each change to each file sequentially.  For
+    example, this patch will swap a and b:
+
+      diff --git a/a b/b
+      rename from a
+      rename to b
+      diff --git a/b b/a
+      rename from b
+      rename to a
+
+
+combined diff format
+--------------------
+
+Any diff-generating command can take the `-c` or `--cc` option to
+produce a 'combined diff' when showing a merge. This is the default
+format when showing merges with linkgit:git-diff[1] or
+linkgit:git-show[1]. Note also that you can give the `-m` option to any
+of these commands to force generation of diffs with individual parents
+of a merge.

+	The following parameters are available:
++
+--
+`changes`;;
+	Compute the dirstat numbers by counting the lines that have been

+`lines`;;
+	Compute the dirstat numbers by doing the regular line-based diff
+	analysis, and summing the removed/added line counts. (For binary
+	files, count 64-byte chunks instead, since binary files have no
+	natural concept of lines). This is a more expensive `--dirstat`
+	behavior than the `changes` behavior, but it does count rearranged
+	lines within a file as much as other changes. The resulting output
+	is consistent with what you get from the other `--*stat` options.
+`files`;;
+	Compute the dirstat numbers by counting the number of files changed.
+	Each changed file counts equally in the dirstat analysis. This is
+	the computationally cheapest `--dirstat` behavior, since it does
+	not have to look at the file contents at all.
+`cumulative`;;
+	Count changes in a child directory for the parent directory as well.
+	Note that when using `cumulative`, the sum of the percentages
+	reported may exceed 100%. The default (non-cumulative) behavior can
+	be specified with the `noncumulative` parameter.

+highlight the changed parts in all modes if enabled.

+	runs of non-whitespace to be a word.  Also implies
+	`--word-diff` unless it was already enabled.
++
+Every non-overlapping match of the

+considered whitespace and ignored(!) for the purposes of finding
+differences.  You may want to append `|[^[:space:]]` to your regular
+expression to make sure that it matches all non-whitespace characters.
+A match that contains a newline is silently truncated(!) at the
+newline.
++
+The regex can also be set via a diff driver or configuration option, see
+linkgit:gitattributes[1] or linkgit:git-config[1].  Giving it explicitly
+overrides any diff driver or configuration setting.  Diff drivers
+override configuration settings.

 --check::
-	Warn if changes introduce trailing whitespace
-	or an indent that uses a space before a tab.

+	Highlight whitespace errors on lines specified by <kind>
+	in the color specified by `color.diff.whitespace`.  <kind>
+	is a comma separated list of `old`, `new`, `context`.  When
+	this option is not given, only whitespace errors in `new`
+	lines are highlighted.  E.g. `--ws-error-highlight=new,old`

+option (defaults to 60%). `-B/70%` specifies that less than 30% of the
+original should remain in the result for Git to consider it a total
+rewrite (i.e. otherwise the resulting patch will be a series of
+deletion and insertion mixed together with context lines).
++
+When used with -M, a totally-rewritten file is also considered as the
+source of a rename (usually -M only considers a file that disappeared
+as the source of a rename), and the number `n` controls this aspect of
+the -B option (defaults to 50%). `-B20%` specifies that a change with
+addition and deletion compared to 20% or more of the file's size are
+eligible for being picked up as a possible source of a rename to

-Tweaking diff output
-====================
-June 2005
-
-
-Introduction
-------------
-
-The diff commands git-diff-index, git-diff-files, and git-diff-tree
-can be told to manipulate differences they find in
-unconventional ways before showing diff(1) output.  The manipulation
-is collectively called "diffcore transformation".  This short note
-describes what they are and how to use them to produce diff outputs
-that are easier to understand than the conventional kind.
-
-
-The chain of operation
-----------------------
-
-The git-diff-* family works by first comparing two sets of
-files:
-
- - git-diff-index compares contents of a "tree" object and the
-   working directory (when '\--cached' flag is not used) or a
-   "tree" object and the index file (when '\--cached' flag is
-   used);
-
- - git-diff-files compares contents of the index file and the
-   working directory;
-
- - git-diff-tree compares contents of two "tree" objects;
-
-In all of these cases, the commands themselves compare
-corresponding paths in the two sets of files.  The result of
-comparison is passed from these commands to what is internally
-called "diffcore", in a format similar to what is output when
-the -p option is not used.  E.g.
-
-------------------------------------------------
-in-place edit  :100644 100644 bcd1234... 0123456... M file0
-create         :000000 100644 0000000... 1234567... A file4
-delete         :100644 000000 1234567... 0000000... D file5
-unmerged       :000000 000000 0000000... 0000000... U file6
-------------------------------------------------
-
-The diffcore mechanism is fed a list of such comparison results
-(each of which is called "filepair", although at this point each
-of them talks about a single file), and transforms such a list
-into another list.  There are currently 6 such transformations:
-
-- diffcore-pathspec
-- diffcore-break
-- diffcore-rename
-- diffcore-merge-broken
-- diffcore-pickaxe
-- diffcore-order
-
-These are applied in sequence.  The set of filepairs git-diff-\*
-commands find are used as the input to diffcore-pathspec, and
-the output from diffcore-pathspec is used as the input to the
-next transformation.  The final result is then passed to the
-output routine and generates either diff-raw format (see Output
-format sections of the manual for git-diff-\* commands) or
-diff-patch format.
-
-
-diffcore-pathspec: For Ignoring Files Outside Our Consideration
----------------------------------------------------------------
-
-The first transformation in the chain is diffcore-pathspec, and
-is controlled by giving the pathname parameters to the
-git-diff-* commands on the command line.  The pathspec is used
-to limit the world diff operates in.  It removes the filepairs
-outside the specified set of pathnames.  E.g. If the input set 
-of filepairs included:
-
-------------------------------------------------
-:100644 100644 bcd1234... 0123456... M junkfile
-------------------------------------------------
-
-but the command invocation was "git-diff-files myfile", then the
-junkfile entry would be removed from the list because only "myfile"
-is under consideration.
-
-Implementation note.  For performance reasons, git-diff-tree
-uses the pathname parameters on the command line to cull set of
-filepairs it feeds the diffcore mechanism itself, and does not
-use diffcore-pathspec, but the end result is the same.
-
-
-diffcore-break: For Splitting Up "Complete Rewrites"
-----------------------------------------------------
-
-The second transformation in the chain is diffcore-break, and is
-controlled by the -B option to the git-diff-* commands.  This is
-used to detect a filepair that represents "complete rewrite" and
-break such filepair into two filepairs that represent delete and
-create.  E.g.  If the input contained this filepair:
-
-------------------------------------------------
-:100644 100644 bcd1234... 0123456... M file0
-------------------------------------------------
-
-and if it detects that the file "file0" is completely rewritten,
-it changes it to:
-
-------------------------------------------------
-:100644 000000 bcd1234... 0000000... D file0
-:000000 100644 0000000... 0123456... A file0
-------------------------------------------------
-
-For the purpose of breaking a filepair, diffcore-break examines
-the extent of changes between the contents of the files before
-and after modification (i.e. the contents that have "bcd1234..."
-and "0123456..." as their SHA1 content ID, in the above
-example).  The amount of deletion of original contents and
-insertion of new material are added together, and if it exceeds
-the "break score", the filepair is broken into two.  The break
-score defaults to 50% of the size of the smaller of the original
-and the result (i.e. if the edit shrinks the file, the size of
-the result is used; if the edit lengthens the file, the size of
-the original is used), and can be customized by giving a number
-after "-B" option (e.g. "-B75" to tell it to use 75%).
-
-
-diffcore-rename: For Detection Renames and Copies
--------------------------------------------------
-
-This transformation is used to detect renames and copies, and is
-controlled by the -M option (to detect renames) and the -C option
-(to detect copies as well) to the git-diff-* commands.  If the
-input contained these filepairs:
-
-------------------------------------------------
-:100644 000000 0123456... 0000000... D fileX
-:000000 100644 0000000... 0123456... A file0
-------------------------------------------------
-
-and the contents of the deleted file fileX is similar enough to
-the contents of the created file file0, then rename detection
-merges these filepairs and creates:
-
-------------------------------------------------
-:100644 100644 0123456... 0123456... R100 fileX file0
-------------------------------------------------
-
-When the "-C" option is used, the original contents of modified files,
-and deleted files (and also unmodified files, if the
-"\--find-copies-harder" option is used) are considered as candidates
-of the source files in rename/copy operation.  If the input were like
-these filepairs, that talk about a modified file fileY and a newly
-created file file0:
-
-------------------------------------------------
-:100644 100644 0123456... 1234567... M fileY
-:000000 100644 0000000... bcd3456... A file0
-------------------------------------------------
-
-the original contents of fileY and the resulting contents of
-file0 are compared, and if they are similar enough, they are
-changed to:
-
-------------------------------------------------
-:100644 100644 0123456... 1234567... M fileY
-:100644 100644 0123456... bcd3456... C100 fileY file0
-------------------------------------------------
-
-In both rename and copy detection, the same "extent of changes"
-algorithm used in diffcore-break is used to determine if two
-files are "similar enough", and can be customized to use
-a similarity score different from the default of 50% by giving a
-number after the "-M" or "-C" option (e.g. "-M8" to tell it to use
-8/10 = 80%).
-
-Note.  When the "-C" option is used with `\--find-copies-harder`
-option, git-diff-\* commands feed unmodified filepairs to
-diffcore mechanism as well as modified ones.  This lets the copy
-detector consider unmodified files as copy source candidates at
-the expense of making it slower.  Without `\--find-copies-harder`,
-git-diff-\* commands can detect copies only if the file that was
-copied happened to have been modified in the same changeset.
-
-
-diffcore-merge-broken: For Putting "Complete Rewrites" Back Together
---------------------------------------------------------------------
-
-This transformation is used to merge filepairs broken by
-diffcore-break, and not transformed into rename/copy by
-diffcore-rename, back into a single modification.  This always
-runs when diffcore-break is used.
-
-For the purpose of merging broken filepairs back, it uses a
-different "extent of changes" computation from the ones used by
-diffcore-break and diffcore-rename.  It counts only the deletion
-from the original, and does not count insertion.  If you removed
-only 10 lines from a 100-line document, even if you added 910
-new lines to make a new 1000-line document, you did not do a
-complete rewrite.  diffcore-break breaks such a case in order to
-help diffcore-rename to consider such filepairs as candidate of
-rename/copy detection, but if filepairs broken that way were not
-matched with other filepairs to create rename/copy, then this
-transformation merges them back into the original
-"modification".
-
-The "extent of changes" parameter can be tweaked from the
-default 80% (that is, unless more than 80% of the original
-material is deleted, the broken pairs are merged back into a
-single modification) by giving a second number to -B option,
-like these:
-
-* -B50/60 (give 50% "break score" to diffcore-break, use 60%
-  for diffcore-merge-broken).
-
-* -B/60 (the same as above, since diffcore-break defaults to 50%).
-
-Note that earlier implementation left a broken pair as a separate
-creation and deletion patches.  This was an unnecessary hack and
-the latest implementation always merges all the broken pairs
-back into modifications, but the resulting patch output is
-formatted differently for easier review in case of such

-diffcore-pickaxe: For Detecting Addition/Deletion of Specified String
----------------------------------------------------------------------
-
-This transformation is used to find filepairs that represent
-changes that touch a specified string, and is controlled by the
--S option and the `\--pickaxe-all` option to the git-diff-*
-commands.
-
-When diffcore-pickaxe is in use, it checks if there are
-filepairs whose "original" side has the specified string and
-whose "result" side does not.  Such a filepair represents "the
-string appeared in this changeset".  It also checks for the
-opposite case that loses the specified string.
-
-When `\--pickaxe-all` is not in effect, diffcore-pickaxe leaves
-only such filepairs that touch the specified string in its
-output.  When `\--pickaxe-all` is used, diffcore-pickaxe leaves all
-filepairs intact if there is such a filepair, or makes the
-output empty otherwise.  The latter behaviour is designed to
-make reviewing of the changes in the context of the whole
-changeset easier.
-
-
-diffcore-order: For Sorting the Output Based on Filenames
----------------------------------------------------------
-
-This is used to reorder the filepairs according to the user's
-(or project's) taste, and is controlled by the -O option to the
-git-diff-* commands.
-
-This takes a text file each of whose lines is a shell glob
-pattern.  Filepairs that match a glob pattern on an earlier line
-in the file are output before ones that match a later line, and
-filepairs that do not match any glob pattern are output last.
-
-As an example, a typical orderfile for the core git probably
-would look like this:
-
-------------------------------------------------
-README
-Makefile
-Documentation
-*.h
-*.c
-t

-Everyday GIT With 20 Commands Or So
-===================================
-
-<<Basic Repository>> commands are needed by people who have a
-repository --- that is everybody, because every working tree of
-git is a repository.
-
-In addition, <<Individual Developer (Standalone)>> commands are
-essential for anybody who makes a commit, even for somebody who
-works alone.
-
-If you work with other people, you will need commands listed in
-the <<Individual Developer (Participant)>> section as well.
-
-People who play the <<Integrator>> role need to learn some more
-commands in addition to the above.
-
-<<Repository Administration>> commands are for system
-administrators who are responsible for the care and feeding
-of git repositories.
-
-
-Basic Repository[[Basic Repository]]
-------------------------------------
-
-Everybody uses these commands to maintain git repositories.
-
-  * gitlink:git-init[1] or gitlink:git-clone[1] to create a
-    new repository.
-
-  * gitlink:git-fsck[1] to check the repository for errors.
-
-  * gitlink:git-prune[1] to remove unused objects in the repository.
-
-  * gitlink:git-repack[1] to pack loose objects for efficiency.
-
-  * gitlink:git-gc[1] to do common housekeeping tasks such as
-    repack and prune.
-
-Examples
-~~~~~~~~
-
-Check health and remove cruft.::
-+
-------------
-$ git fsck <1>
-$ git count-objects <2>
-$ git repack <3>
-$ git gc <4>
-------------
-+
-<1> running without `\--full` is usually cheap and assures the
-repository health reasonably well.
-<2> check how many loose objects there are and how much
-disk space is wasted by not repacking.
-<3> without `-a` repacks incrementally.  repacking every 4-5MB
-of loose objects accumulation may be a good rule of thumb.
-<4> it is easier to use `git gc` than individual housekeeping commands
-such as `prune` and `repack`.  This runs `repack -a -d`.
-
-Repack a small project into single pack.::
-+
-------------
-$ git repack -a -d <1>
-$ git prune
-------------
-+
-<1> pack all the objects reachable from the refs into one pack,
-then remove the other packs.
-
-
-Individual Developer (Standalone)[[Individual Developer (Standalone)]]
-----------------------------------------------------------------------
-
-A standalone individual developer does not exchange patches with
-other people, and works alone in a single repository, using the
-following commands.
-
-  * gitlink:git-show-branch[1] to see where you are.
-
-  * gitlink:git-log[1] to see what happened.
-
-  * gitlink:git-checkout[1] and gitlink:git-branch[1] to switch
-    branches.
-
-  * gitlink:git-add[1] to manage the index file.
-
-  * gitlink:git-diff[1] and gitlink:git-status[1] to see what
-    you are in the middle of doing.
-
-  * gitlink:git-commit[1] to advance the current branch.
-
-  * gitlink:git-reset[1] and gitlink:git-checkout[1] (with
-    pathname parameters) to undo changes.
-
-  * gitlink:git-merge[1] to merge between local branches.
-
-  * gitlink:git-rebase[1] to maintain topic branches.
-
-  * gitlink:git-tag[1] to mark known point.
-
-Examples
-~~~~~~~~
-
-Use a tarball as a starting point for a new repository.::
-+
-------------
-$ tar zxf frotz.tar.gz
-$ cd frotz
-$ git-init
-$ git add . <1>
-$ git commit -m 'import of frotz source tree.'
-$ git tag v2.43 <2>
-------------
-+
-<1> add everything under the current directory.
-<2> make a lightweight, unannotated tag.
-
-Create a topic branch and develop.::
-+
-------------
-$ git checkout -b alsa-audio <1>
-$ edit/compile/test
-$ git checkout -- curses/ux_audio_oss.c <2>
-$ git add curses/ux_audio_alsa.c <3>
-$ edit/compile/test
-$ git diff HEAD <4>
-$ git commit -a -s <5>
-$ edit/compile/test
-$ git reset --soft HEAD^ <6>
-$ edit/compile/test
-$ git diff ORIG_HEAD <7>
-$ git commit -a -c ORIG_HEAD <8>
-$ git checkout master <9>
-$ git merge alsa-audio <10>
-$ git log --since='3 days ago' <11>
-$ git log v2.43.. curses/ <12>
-------------
-+
-<1> create a new topic branch.
-<2> revert your botched changes in `curses/ux_audio_oss.c`.
-<3> you need to tell git if you added a new file; removal and
-modification will be caught if you do `git commit -a` later.
-<4> to see what changes you are committing.
-<5> commit everything as you have tested, with your sign-off.
-<6> take the last commit back, keeping what is in the working tree.
-<7> look at the changes since the premature commit we took back.
-<8> redo the commit undone in the previous step, using the message
-you originally wrote.
-<9> switch to the master branch.
-<10> merge a topic branch into your master branch.
-<11> review commit logs; other forms to limit output can be
-combined and include `\--max-count=10` (show 10 commits),
-`\--until=2005-12-10`, etc.
-<12> view only the changes that touch what's in `curses/`
-directory, since `v2.43` tag.
-
-
-Individual Developer (Participant)[[Individual Developer (Participant)]]
-------------------------------------------------------------------------
-
-A developer working as a participant in a group project needs to
-learn how to communicate with others, and uses these commands in
-addition to the ones needed by a standalone developer.
-
-  * gitlink:git-clone[1] from the upstream to prime your local
-    repository.
-
-  * gitlink:git-pull[1] and gitlink:git-fetch[1] from "origin"
-    to keep up-to-date with the upstream.
-
-  * gitlink:git-push[1] to shared repository, if you adopt CVS
-    style shared repository workflow.
-
-  * gitlink:git-format-patch[1] to prepare e-mail submission, if
-    you adopt Linux kernel-style public forum workflow.
-
-Examples
-~~~~~~~~
-
-Clone the upstream and work on it.  Feed changes to upstream.::
-+
-------------
-$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
-$ cd my2.6
-$ edit/compile/test; git commit -a -s <1>

-------------
-+
-<1> repeat as needed.
-<2> extract patches from your branch for e-mail submission.
-<3> `git pull` fetches from `origin` by default and merges into the
-current branch.
-<4> immediately after pulling, look at the changes done upstream
-since last time we checked, only in the
-area we are interested in.
-<5> fetch from a specific branch from a specific repository and merge.
-<6> revert the pull.
-<7> garbage collect leftover objects from reverted pull.
-<8> from time to time, obtain official tags from the `origin`
-and store them under `.git/refs/tags/`.
-
-
-Push into another repository.::
-+
-------------
-satellite$ git clone mothership:frotz frotz <1>
-satellite$ cd frotz
-satellite$ git config --get-regexp '^(remote|branch)\.' <2>
-remote.origin.url mothership:frotz
-remote.origin.fetch refs/heads/*:refs/remotes/origin/*
-branch.master.remote origin
-branch.master.merge refs/heads/master
-satellite$ git config remote.origin.push \
-           master:refs/remotes/satellite/master <3>
-satellite$ edit/compile/test/commit
-satellite$ git push origin <4>
-
-mothership$ cd frotz
-mothership$ git checkout master
-mothership$ git merge satellite/master <5>
-------------
-+
-<1> mothership machine has a frotz repository under your home
-directory; clone from it to start a repository on the satellite
-machine.
-<2> clone sets these configuration variables by default.
-It arranges `git pull` to fetch and store the branches of mothership
-machine to local `remotes/origin/*` tracking branches.
-<3> arrange `git push` to push local `master` branch to
-`remotes/satellite/master` branch of the mothership machine.
-<4> push will stash our work away on `remotes/satellite/master`
-tracking branch on the mothership machine.  You could use this as
-a back-up method.
-<5> on mothership machine, merge the work done on the satellite
-machine into the master branch.
-
-Branch off of a specific tag.::
-+
-------------
-$ git checkout -b private2.6.14 v2.6.14 <1>
-$ edit/compile/test; git commit -a
-$ git checkout master
-$ git format-patch -k -m --stdout v2.6.14..private2.6.14 |
-  git am -3 -k <2>
-------------
-+
-<1> create a private branch based on a well known (but somewhat behind)
-tag.
-<2> forward port all changes in `private2.6.14` branch to `master` branch
-without a formal "merging".

-Integrator[[Integrator]]
-------------------------
-
-A fairly central person acting as the integrator in a group
-project receives changes made by others, reviews and integrates
-them and publishes the result for others to use, using these
-commands in addition to the ones needed by participants.
-
-  * gitlink:git-am[1] to apply patches e-mailed in from your
-    contributors.
-
-  * gitlink:git-pull[1] to merge from your trusted lieutenants.
-
-  * gitlink:git-format-patch[1] to prepare and send suggested
-    alternative to contributors.
-
-  * gitlink:git-revert[1] to undo botched commits.
-
-  * gitlink:git-push[1] to publish the bleeding edge.

-My typical GIT day.::
-+
-------------
-$ git status <1>
-$ git show-branch <2>
-$ mailx <3>
-& s 2 3 4 5 ./+to-apply
-& s 7 8 ./+hold-linus

-$ git fetch ko && git show-branch master maint 'tags/ko-*' <11>
-$ git push ko <12>
-$ git push ko v0.99.9x <13>
-------------
-+
-<1> see what I was in the middle of doing, if any.
-<2> see what topic branches I have and think about how ready
-they are.
-<3> read mails, save ones that are applicable, and save others
-that are not quite ready.
-<4> apply them, interactively, with my sign-offs.
-<5> create topic branch as needed and apply, again with my
-sign-offs.
-<6> rebase internal topic branch that has not been merged to the
-master, nor exposed as a part of a stable branch.
-<7> restart `pu` every time from the next.
-<8> and bundle topic branches still cooking.
-<9> backport a critical fix.
-<10> create a signed tag.
-<11> make sure I did not accidentally rewind master beyond what I
-already pushed out.  `ko` shorthand points at the repository I have
-at kernel.org, and looks like this:
-+
-------------
-$ cat .git/remotes/ko
-URL: kernel.org:/pub/scm/git/git.git
-Pull: master:refs/tags/ko-master
-Pull: next:refs/tags/ko-next
-Pull: maint:refs/tags/ko-maint
-Push: master
-Push: next
-Push: +pu
-Push: maint
-------------
-+
-In the output from `git show-branch`, `master` should have
-everything `ko-master` has, and `next` should have
-everything `ko-next` has.
-
-<12> push out the bleeding edge.
-<13> push the tag out, too.
-
-
-Repository Administration[[Repository Administration]]
-------------------------------------------------------
-
-A repository administrator uses the following tools to set up
-and maintain access to the repository by developers.
-
-  * gitlink:git-daemon[1] to allow anonymous download from
-    repository.
-
-  * gitlink:git-shell[1] can be used as a 'restricted login shell'
-    for shared central repository users.
-
-link:howto/update-hook-example.txt[update hook howto] has a good
-example of managing a shared central repository.
-
-
-Examples
-~~~~~~~~
-We assume the following in /etc/services::
-+
-------------
-$ grep 9418 /etc/services
-git		9418/tcp		# Git Version Control System
-------------
-
-Run git-daemon to serve /pub/scm from inetd.::
-+
-------------
-$ grep git /etc/inetd.conf
-git	stream	tcp	nowait	nobody \
-  /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
-------------
-+
-The actual configuration line should be on one line.
-
-Run git-daemon to serve /pub/scm from xinetd.::
-+
-------------
-$ cat /etc/xinetd.d/git-daemon
-# default: off
-# description: The git server offers access to git repositories
-service git
-{
-        disable = no
-        type            = UNLISTED
-        port            = 9418
-        socket_type     = stream
-        wait            = no
-        user            = nobody
-        server          = /usr/bin/git-daemon
-        server_args     = --inetd --export-all --base-path=/pub/scm
-        log_on_failure  += USERID
-}
-------------
-+
-Check your xinetd(8) documentation and setup, this is from a Fedora system.
-Others might be different.
-
-Give push/pull only access to developers.::
-+
-------------
-$ grep git /etc/passwd <1>
-alice:x:1000:1000::/home/alice:/usr/bin/git-shell

-david:x:1003:1003::/home/david:/usr/bin/git-shell
-$ grep git /etc/shells <2>
-/usr/bin/git-shell
-------------
-+
-<1> log-in shell is set to /usr/bin/git-shell, which does not
-allow anything but `git push` and `git pull`.  The users should
-get an ssh access to the machine.
-<2> in many distributions /etc/shells needs to list what is used
-as the login shell.
-
-CVS-style shared repository.::

-------------
-+
-<1> place the developers into the same git group.
-<2> and make the shared repository writable by the group.
-<3> use update-hook example by Carl from Documentation/howto/
-for branch policy control.
-<4> alice and cindy can push into master, only bob can push into doc-update.

+	  [--] [<pathspec>...]
 
 DESCRIPTION
 -----------
-All the changed file contents to be committed together in a single set
-of changes must be "added" with the 'add' command before using the
-'commit' command.  This is not only for adding new files.  Even modified
-files must be added to the set of changes about to be committed.
-
-This command can be performed multiple times before a commit. The added
-content corresponds to the state of specified file(s) at the time the
-'add' command is used. This means the 'commit' command will not consider
-subsequent changes to already added content if it is not added again before
-the commit.
-
-The 'git status' command can be used to obtain a summary of what is included
-for the next commit.
-
-This command can be used to add ignored files with `-f` (force)
-option, but they have to be
-explicitly and exactly specified from the command line.  File globbing
-and recursive behaviour do not add ignored files.
-
-Please see gitlink:git-commit[1] for alternative ways to add content to a
+This command updates the index using the current content found in
+the working tree, to prepare the content staged for the next commit.
+It typically adds the current content of existing paths as a whole,
+but with some options it can also be used to add content with
+only part of the changes made to the working tree files applied, or
+remove paths that do not exist in the working tree anymore.
+
+The "index" holds a snapshot of the content of the working tree, and it
+is this snapshot that is taken as the contents of the next commit.  Thus
+after making any changes to the working directory, and before running
+the commit command, you must use the `add` command to add any new or
+modified files to the index.
+
+This command can be performed multiple times before a commit.  It only
+adds the content of the specified file(s) at the time the add command is
+run; if you want subsequent changes included in the next commit, then
+you must run `git add` again to add the new content to the index.
+
+The `git status` command can be used to obtain a summary of which
+files have changes that are staged for the next commit.
+
+The `git add` command will not add ignored files by default.  If any
+ignored files were explicitly specified on the command line, `git add`
+will fail with a list of ignored files.  Ignored files reached by
+directory recursion or filename globbing performed by Git (quote your
+globs before the shell) will be silently ignored.  The 'git add' command can
+be used to add ignored files with the `-f` (force) option.
+
+Please see linkgit:git-commit[1] for alternative ways to add content to a
 commit.
 
 
 OPTIONS
 -------
-<file>...::
+<pathspec>...::
 	Files to add content from.  Fileglobs (e.g. `*.c`) can
 	be given to add all matching files.  Also a
 	leading directory name (e.g. `dir` to add `dir/file1`
-	and `dir/file2`) can be given to add all files in the
-	directory, recursively.
+	and `dir/file2`) can be given to update the index to
+	match the current state of the directory as a whole (e.g.
+	specifying `dir` will record not just a file `dir/file1`
+	modified in the working tree, a file `dir/file2` added to
+	the working tree, but also a file `dir/file3` removed from
+	the working tree.  Note that older versions of Git used
+	to ignore removed files; use `--no-all` option if you want
+	to add modified or new files but ignore removed	ones.
 
 -n::
-        Don't actually add the file(s), just show if they exist.
+--dry-run::
+	Don't actually add the file(s), just show if they exist and/or will
+	be ignored.
 
 -v::
+--verbose::
         Be verbose.
 
 -f::
+--force::
 	Allow adding otherwise ignored files.
 
--i, \--interactive::
+-i::
+--interactive::
 	Add modified contents in the working tree interactively to
-	the index.
+	the index. Optional path arguments may be supplied to limit
+	operation to a subset of the working tree. See ``Interactive
+	mode'' for details.
+
+-p::
+--patch::
+	Interactively choose hunks of patch between the index and the
+	work tree and add them to the index. This gives the user a chance
+	to review the difference before adding modified contents to the
+	index.
++
+This effectively runs `add --interactive`, but bypasses the
+initial command menu and directly jumps to the `patch` subcommand.
+See ``Interactive mode'' for details.
+
+-e::
+--edit::
+	Open the diff vs. the index in an editor and let the user
+	edit it.  After the editor was closed, adjust the hunk headers
+	and apply the patch to the index.
++
+The intent of this option is to pick and choose lines of the patch to
+apply, or even to modify the contents of lines to be staged. This can be
+quicker and more flexible than using the interactive hunk selector.
+However, it is easy to confuse oneself and create a patch that does not

+Invoking `git add -e` or selecting `e` from the interactive hunk
+selector will open a patch in your editor; after the editor exits, the
+result is applied to the index. You are free to make arbitrary changes
+to the patch, but note that some changes may have confusing results, or
+even result in a patch that cannot be applied.  If you want to abort the
+operation entirely (i.e., stage nothing new in the index), simply delete
+all lines of the patch. The list below describes some common things you
+may see in a patch, and which editing operations make sense on them.
 
-Documentation

-Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>.
+--
+added content::
+
+Added content is represented by lines beginning with "{plus}". You can
+prevent staging any addition lines by deleting them.
+
+removed content::
+
+Removed content is represented by lines beginning with "-". You can
+prevent staging their removal by converting the "-" to a " " (space).
+
+modified content::
+
+Modified content is represented by "-" lines (removing the old content)
+followed by "{plus}" lines (adding the replacement content). You can
+prevent staging the modification by converting "-" lines to " ", and
+removing "{plus}" lines. Beware that modifying only half of the pair is
+likely to introduce confusing changes to the index.
+--
+
+There are also more complex operations that can be performed. But beware
+that because the patch is applied only to the index and not the working
+tree, the working tree will appear to "undo" the change in the index.
+For example, introducing a new line into the index that is in neither
+the HEAD nor the working tree will stage the new line for commit, but
+the line will appear to be reverted in the working tree.
+
+Avoid using these constructs, or do so with extreme caution.
+
+--
+removing untouched content::
+
+Content which does not differ between the index and working tree may be
+shown on context lines, beginning with a " " (space).  You can stage
+context lines for removal by converting the space to a "-". The
+resulting working tree file will appear to re-add the content.
+
+modifying existing content::
+
+One can also modify context lines by staging them for removal (by
+converting " " to "-") and adding a "{plus}" line with the new content.
+Similarly, one can modify "{plus}" lines for existing additions or
+modifications. In all cases, the new modification will appear reverted
+in the working tree.
+
+new content::
+
+You may also add new content that does not exist in the patch; simply
+add new lines, each starting with "{plus}". The addition will appear
+reverted in the working tree.
+--
+
+There are also several operations which should be avoided entirely, as
+they will make the patch impossible to apply:
+
+* adding context (" ") or removal ("-") lines
+* deleting context or removal lines
+* modifying the contents of context or removal lines

 DISCUSSION
 ----------
 
-When initially invoking it, you give it names of the mailboxes
-to crunch.  Upon seeing the first patch that does not apply, it
-aborts in the middle, just like 'git-applymbox' does.  You can
-recover from this in one of two ways:
+The commit author name is taken from the "From: " line of the
+message, and commit author date is taken from the "Date: " line
+of the message.  The "Subject: " line is used as the title of
+the commit, after stripping common prefix "[PATCH <anything>]".
+The "Subject: " line is supposed to concisely describe what the
+commit is about in one line of text.
+
+"From: " and "Subject: " lines starting the body override the respective
+commit author name and title values taken from the headers.
+
+The commit message is formed by the title taken from the
+"Subject: ", a blank line and the body of the message up to
+where the patch begins.  Excess whitespace at the end of each
+line is automatically stripped.
+
+The patch is expected to be inline, directly following the
+message.  Any line that is of the form:
+
+* three-dashes and end-of-line, or
+* a line that begins with "diff -", or
+* a line that begins with "Index: "
+
+is taken as the beginning of a patch, and the commit log message
+is terminated before the first occurrence of such a line.

+The command refuses to process new mailboxes until the current
+operation is finished, so if you decide to start over from scratch,
+run `git am --abort` before running the command with mailbox

+Before any patches are applied, ORIG_HEAD is set to the tip of the
+current branch.  This is useful if you have problems with multiple
+commits, like running 'git am' on the wrong branch or an error in the
+commits that is more easily fixed by changing the mailbox (e.g.
+errors in the "From:" lines).

-
-DESCRIPTION
------------
-Splits mail messages in a mailbox into commit log message,

-
-
-OPTIONS
--------
--q::
-	Apply patches interactively.  The user will be given
-	opportunity to edit the log message and the patch before
-	attempting to apply it.
-
--k::
-	Usually the program 'cleans up' the Subject: header line
-	to extract the title line for the commit log message,
-	among which (1) remove 'Re:' or 're:', (2) leading
-	whitespaces, (3) '[' up to ']', typically '[PATCH]', and
-	then prepends "[PATCH] ".  This flag forbids this
-	munging, and is most useful when used to read back 'git
-	format-patch --mbox' output.
-
--m::
-	Patches are applied with `git-apply` command, and unless
-	it cleanly applies without fuzz, the processing fails.
-	With this flag, if a tree that the patch applies cleanly
-	is found in a repository, the patch is applied to the
-	tree and then a 3-way merge between the resulting tree
-	and the current tree.
-
--u::
-	The commit log message, author name and author email are
-	taken from the e-mail, and after minimally decoding MIME
-	transfer encoding, re-coded in UTF-8 by transliterating
-	them.  This used to be optional but now it is the default.
-+
-Note that the patch is always used as-is without charset
-conversion, even with this flag.
-
--c .dotest/<num>::
-	When the patch contained in an e-mail does not cleanly
-	apply, the command exits with an error message. The
-	patch and extracted message are found in .dotest/, and
-	you could re-run 'git applymbox' with '-c .dotest/<num>'

-
-<signoff>::
-	The name of the file that contains your "Signed-off-by"
-	line.  See 'SubmittingPatches' document to learn what
-	"Signed-off-by" line means.  You can also just say
-	'yes', 'true', 'me', or 'please' to use an automatically
-	generated "Signed-off-by" line based on your committer
-	identity.

-will be used instead. The default value remains 0, which means world
-readable/writable files and directories.
+tar.umask::
+	This variable can be used to restrict the permission bits of
+	tar archive entries.  The default is 0002, which turns off the
+	world write bit.  The special value "user" indicates that the

+tar.<format>.command::
+	This variable specifies a shell command through which the tar
+	output generated by `git archive` should be piped. The command
+	is executed using the shell with the generated tar file on its
+	standard input, and should produce the final output on its
+	standard output. Any compression-level options will be passed

+export-subst::
+	If the attribute export-subst is set for a file then Git will
+	expand several placeholders when adding this file to an archive.
+	See linkgit:gitattributes[5] for details.
+
+Note that attributes are by default taken from the `.gitattributes` files
+in the tree that is being archived.  If you want to tweak the way the
+output is generated after the fact (e.g. you committed without adding an
+appropriate export-ignore in its `.gitattributes`), adjust the checked out
+`.gitattributes` file as necessary and use `--worktree-attributes`
+option.  Alternatively you can keep necessary attributes that should apply
+while archiving any tree in your `$GIT_DIR/info/attributes` file.

+Fighting regressions with git bisect
+====================================
+:Author: Christian Couder
+:Email: chriscool@tuxfamily.org
+:Date: 2009/11/08
+
+Abstract
+--------
+
+"git bisect" enables software users and developers to easily find the
+commit that introduced a regression. We show why it is important to
+have good tools to fight regressions. We describe how "git bisect"
+works from the outside and the algorithms it uses inside. Then we
+explain how to take advantage of "git bisect" to improve current
+practices. And we discuss how "git bisect" could improve in the
+future.
+
+
+Introduction to "git bisect"
+----------------------------
+
+Git is a Distributed Version Control system (DVCS) created by Linus
+Torvalds and maintained by Junio Hamano.
+
+In Git like in many other Version Control Systems (VCS), the different
+states of the data that is managed by the system are called
+commits. And, as VCS are mostly used to manage software source code,
+sometimes "interesting" changes of behavior in the software are
+introduced in some commits.
+
+In fact people are specially interested in commits that introduce a
+"bad" behavior, called a bug or a regression. They are interested in
+these commits because a commit (hopefully) contains a very small set
+of source code changes. And it's much easier to understand and
+properly fix a problem when you only need to check a very small set of
+changes, than when you don't know where look in the first place.
+
+So to help people find commits that introduce a "bad" behavior, the
+"git bisect" set of commands was invented. And it follows of course
+that in "git bisect" parlance, commits where the "interesting
+behavior" is present are called "bad" commits, while other commits are
+called "good" commits. And a commit that introduce the behavior we are
+interested in is called a "first bad commit". Note that there could be
+more than one "first bad commit" in the commit space we are searching.
+
+So "git bisect" is designed to help find a "first bad commit". And to
+be as efficient as possible, it tries to perform a binary search.
+
+
+Fighting regressions overview
+-----------------------------
+
+Regressions: a big problem
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Regressions are a big problem in the software industry. But it's
+difficult to put some real numbers behind that claim.
+
+There are some numbers about bugs in general, like a NIST study in
+2002 <<1>> that said:
+
+_____________
+Software bugs, or errors, are so prevalent and so detrimental that
+they cost the U.S. economy an estimated $59.5 billion annually, or
+about 0.6 percent of the gross domestic product, according to a newly
+released study commissioned by the Department of Commerce's National
+Institute of Standards and Technology (NIST). At the national level,
+over half of the costs are borne by software users and the remainder
+by software developers/vendors.  The study also found that, although
+all errors cannot be removed, more than a third of these costs, or an
+estimated $22.2 billion, could be eliminated by an improved testing
+infrastructure that enables earlier and more effective identification
+and removal of software defects. These are the savings associated with
+finding an increased percentage (but not 100 percent) of errors closer
+to the development stages in which they are introduced. Currently,
+over half of all errors are not found until "downstream" in the
+development process or during post-sale software use.
+_____________
+
+And then:
+
+_____________
+Software developers already spend approximately 80 percent of
+development costs on identifying and correcting defects, and yet few
+products of any type other than software are shipped with such high
+levels of errors.
+_____________
+
+Eventually the conclusion started with:
+
+_____________
+The path to higher software quality is significantly improved software
+testing.
+_____________
+
+There are other estimates saying that 80% of the cost related to
+software is about maintenance <<2>>.
+
+Though, according to Wikipedia <<3>>:
+
+_____________
+A common perception of maintenance is that it is merely fixing
+bugs. However, studies and surveys over the years have indicated that
+the majority, over 80%, of the maintenance effort is used for
+non-corrective actions (Pigosky 1997). This perception is perpetuated
+by users submitting problem reports that in reality are functionality
+enhancements to the system.
+_____________
+
+But we can guess that improving on existing software is very costly
+because you have to watch out for regressions. At least this would
+make the above studies consistent among themselves.
+
+Of course some kind of software is developed, then used during some
+time without being improved on much, and then finally thrown away. In
+this case, of course, regressions may not be a big problem. But on the
+other hand, there is a lot of big software that is continually
+developed and maintained during years or even tens of years by a lot
+of people. And as there are often many people who depend (sometimes
+critically) on such software, regressions are a really big problem.
+
+One such software is the Linux kernel. And if we look at the Linux
+kernel, we can see that a lot of time and effort is spent to fight
+regressions. The release cycle start with a 2 weeks long merge
+window. Then the first release candidate (rc) version is tagged. And
+after that about 7 or 8 more rc versions will appear with around one
+week between each of them, before the final release.
+
+The time between the first rc release and the final release is
+supposed to be used to test rc versions and fight bugs and especially
+regressions. And this time is more than 80% of the release cycle
+time. But this is not the end of the fight yet, as of course it
+continues after the release.
+
+And then this is what Ingo Molnar (a well known Linux kernel
+developer) says about his use of git bisect:
+
+_____________
+I most actively use it during the merge window (when a lot of trees
+get merged upstream and when the influx of bugs is the highest) - and
+yes, there have been cases that i used it multiple times a day. My
+average is roughly once a day.
+_____________
+
+So regressions are fought all the time by developers, and indeed it is
+well known that bugs should be fixed as soon as possible, so as soon
+as they are found. That's why it is interesting to have good tools for
+this purpose.
+
+Other tools to fight regressions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+So what are the tools used to fight regressions? They are nearly the
+same as those used to fight regular bugs. The only specific tools are
+test suites and tools similar as "git bisect".
+
+Test suites are very nice. But when they are used alone, they are
+supposed to be used so that all the tests are checked after each
+commit. This means that they are not very efficient, because many
+tests are run for no interesting result, and they suffer from
+combinational explosion.
+
+In fact the problem is that big software often has many different
+configuration options and that each test case should pass for each
+configuration after each commit. So if you have for each release: N
+configurations, M commits and T test cases, you should perform:
+
+-------------
+N * M * T tests
+-------------
+
+where N, M and T are all growing with the size your software.
+
+So very soon it will not be possible to completely test everything.
+
+And if some bugs slip through your test suite, then you can add a test
+to your test suite. But if you want to use your new improved test
+suite to find where the bug slipped in, then you will either have to
+emulate a bisection process or you will perhaps bluntly test each
+commit backward starting from the "bad" commit you have which may be
+very wasteful.
+
+"git bisect" overview
+---------------------
+
+Starting a bisection
+~~~~~~~~~~~~~~~~~~~~
+
+The first "git bisect" subcommand to use is "git bisect start" to
+start the search. Then bounds must be set to limit the commit
+space. This is done usually by giving one "bad" and at least one
+"good" commit. They can be passed in the initial call to "git bisect
+start" like this:
+
+-------------
+$ git bisect start [BAD [GOOD...]]
+-------------
+
+or they can be set using:
+
+-------------
+$ git bisect bad [COMMIT]
+-------------
+
+and:
+
+-------------
+$ git bisect good [COMMIT...]
+-------------
+
+where BAD, GOOD and COMMIT are all names that can be resolved to a
+commit.
+
+Then "git bisect" will checkout a commit of its choosing and ask the
+user to test it, like this:
+
+-------------
+$ git bisect start v2.6.27 v2.6.25
+Bisecting: 10928 revisions left to test after this (roughly 14 steps)
+[2ec65f8b89ea003c27ff7723525a2ee335a2b393] x86: clean up using max_low_pfn on 32-bit
+-------------
+
+Note that the example that we will use is really a toy example, we
+will be looking for the first commit that has a version like
+"2.6.26-something", that is the commit that has a "SUBLEVEL = 26" line
+in the top level Makefile. This is a toy example because there are
+better ways to find this commit with Git than using "git bisect" (for
+example "git blame" or "git log -S<string>").
+
+Driving a bisection manually
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+At this point there are basically 2 ways to drive the search. It can
+be driven manually by the user or it can be driven automatically by a
+script or a command.
+
+If the user is driving it, then at each step of the search, the user
+will have to test the current commit and say if it is "good" or "bad"
+using the "git bisect good" or "git bisect bad" commands respectively
+that have been described above. For example:
+
+-------------
+$ git bisect bad
+Bisecting: 5480 revisions left to test after this (roughly 13 steps)
+[66c0b394f08fd89236515c1c84485ea712a157be] KVM: kill file->f_count abuse in kvm
+-------------
+
+And after a few more steps like that, "git bisect" will eventually
+find a first bad commit:
+
+-------------
+$ git bisect bad
+2ddcca36c8bcfa251724fe342c8327451988be0d is the first bad commit

+

+-------------
+
+At this point we can see what the commit does, check it out (if it's
+not already checked out) or tinker with it, for example:
+
+-------------
+$ git show HEAD

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+

+Author: Linus Torvalds <torvalds@linux-foundation.org>
+Date:   Sat May 3 11:59:44 2008 -0700

+
+:100644 100644 5cf82581... 4492984e... M      Makefile
+bisect run success
+-------------
+
+In this example, we passed "grep '^SUBLEVEL = 25' Makefile" as
+parameter to "git bisect run". This means that at each step, the grep
+command we passed will be launched. And if it exits with code 0 (that
+means success) then git bisect will mark the current state as
+"good". If it exits with code 1 (or any code between 1 and 127
+included, except the special code 125), then the current state will be
+marked as "bad".
+
+Exit code between 128 and 255 are special to "git bisect run". They
+make it stop immediately the bisection process. This is useful for
+example if the command passed takes too long to complete, because you
+can kill it with a signal and it will stop the bisection process.
+
+It can also be useful in scripts passed to "git bisect run" to "exit
+255" if some very abnormal situation is detected.
+
+Avoiding untestable commits
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes it happens that the current state cannot be tested, for
+example if it does not compile because there was a bug preventing it
+at that time. This is what the special exit code 125 is for. It tells
+"git bisect run" that the current commit should be marked as
+untestable and that another one should be chosen and checked out.
+
+If the bisection process is driven manually, you can use "git bisect
+skip" to do the same thing. (In fact the special exit code 125 makes
+"git bisect run" use "git bisect skip" in the background.)
+
+Or if you want more control, you can inspect the current state using
+for example "git bisect visualize". It will launch gitk (or "git log"
+if the DISPLAY environment variable is not set) to help you find a
+better bisection point.
+
+Either way, if you have a string of untestable commits, it might
+happen that the regression you are looking for has been introduced by
+one of these untestable commits. In this case it's not possible to
+tell for sure which commit introduced the regression.
+
+So if you used "git bisect skip" (or the run script exited with
+special code 125) you could get a result like this:
+
+-------------
+There are only 'skip'ped commits left to test.
+The first bad commit could be any of:
+15722f2fa328eaba97022898a305ffc8172db6b1

+070eab2303024706f2924822bfec8b9847e4ac1b
+We cannot bisect more!
+-------------
+
+Saving a log and replaying it
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to show other people your bisection process, you can get a
+log using for example:
+
+-------------
+$ git bisect log > bisect_log.txt
+-------------
+
+And it is possible to replay it using:
+
+-------------
+$ git bisect replay bisect_log.txt
+-------------
+
+
+"git bisect" details
+--------------------
+
+Bisection algorithm
+~~~~~~~~~~~~~~~~~~~
+
+As the Git commits form a directed acyclic graph (DAG), finding the
+best bisection commit to test at each step is not so simple. Anyway
+Linus found and implemented a "truly stupid" algorithm, later improved
+by Junio Hamano, that works quite well.
+
+So the algorithm used by "git bisect" to find the best bisection
+commit when there are no skipped commits is the following:
+
+1) keep only the commits that:
+
+a) are ancestor of the "bad" commit (including the "bad" commit itself),
+b) are not ancestor of a "good" commit (excluding the "good" commits).
+
+This means that we get rid of the uninteresting commits in the DAG.
+
+For example if we start with a graph like this:
+
+-------------
+G-Y-G-W-W-W-X-X-X-X
+	   \ /
+	    W-W-B
+	   /
+Y---G-W---W
+ \ /   \
+Y-Y     X-X-X-X
+
+-> time goes this way ->
+-------------
+
+where B is the "bad" commit, "G" are "good" commits and W, X, and Y
+are other commits, we will get the following graph after this first
+step:
+
+-------------
+W-W-W
+     \
+      W-W-B
+     /
+W---W
+-------------
+
+So only the W and B commits will be kept. Because commits X and Y will
+have been removed by rules a) and b) respectively, and because commits
+G are removed by rule b) too.
+
+Note for Git users, that it is equivalent as keeping only the commit
+given by:
+
+-------------
+git rev-list BAD --not GOOD1 GOOD2...
+-------------
+
+Also note that we don't require the commits that are kept to be
+descendants of a "good" commit. So in the following example, commits W
+and Z will be kept:
+
+-------------
+G-W-W-W-B
+   /
+Z-Z
+-------------
+
+2) starting from the "good" ends of the graph, associate to each
+commit the number of ancestors it has plus one
+
+For example with the following graph where H is the "bad" commit and A
+and D are some parents of some "good" commits:
+
+-------------
+A-B-C
+     \
+      F-G-H
+     /
+D---E
+-------------
+
+this will give:
+
+-------------
+1 2 3
+A-B-C
+     \6 7 8
+      F-G-H
+1   2/
+D---E
+-------------
+
+3) associate to each commit: min(X, N - X)
+
+where X is the value associated to the commit in step 2) and N is the
+total number of commits in the graph.
+
+In the above example we have N = 8, so this will give:
+
+-------------
+1 2 3
+A-B-C
+     \2 1 0
+      F-G-H
+1   2/
+D---E
+-------------
+
+4) the best bisection point is the commit with the highest associated
+number
+
+So in the above example the best bisection point is commit C.
+
+5) note that some shortcuts are implemented to speed up the algorithm
+
+As we know N from the beginning, we know that min(X, N - X) can't be
+greater than N/2. So during steps 2) and 3), if we would associate N/2
+to a commit, then we know this is the best bisection point. So in this
+case we can just stop processing any other commit and return the
+current commit.
+
+Bisection algorithm debugging
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For any commit graph, you can see the number associated with each
+commit using "git rev-list --bisect-all".
+
+For example, for the above graph, a command like:
+
+-------------
+$ git rev-list --bisect-all BAD --not GOOD1 GOOD2
+-------------
+
+would output something like:
+
+-------------
+e15b73ad3db9b48d7d1ade32f8cd23a751fe0ace (dist=3)

+
+Bisection algorithm discussed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First let's define "best bisection point". We will say that a commit X
+is a best bisection point or a best bisection commit if knowing its
+state ("good" or "bad") gives as much information as possible whether
+the state of the commit happens to be "good" or "bad".
+
+This means that the best bisection commits are the commits where the
+following function is maximum:
+
+-------------
+f(X) = min(information_if_good(X), information_if_bad(X))
+-------------
+
+where information_if_good(X) is the information we get if X is good
+and information_if_bad(X) is the information we get if X is bad.
+
+Now we will suppose that there is only one "first bad commit". This
+means that all its descendants are "bad" and all the other commits are
+"good". And we will suppose that all commits have an equal probability
+of being good or bad, or of being the first bad commit, so knowing the
+state of c commits gives always the same amount of information
+wherever these c commits are on the graph and whatever c is. (So we
+suppose that these commits being for example on a branch or near a
+good or a bad commit does not give more or less information).
+
+Let's also suppose that we have a cleaned up graph like one after step
+1) in the bisection algorithm above. This means that we can measure
+the information we get in terms of number of commit we can remove from
+the graph..
+
+And let's take a commit X in the graph.
+
+If X is found to be "good", then we know that its ancestors are all
+"good", so we want to say that:
+
+-------------
+information_if_good(X) = number_of_ancestors(X)  (TRUE)
+-------------
+
+And this is true because at step 1) b) we remove the ancestors of the
+"good" commits.
+
+If X is found to be "bad", then we know that its descendants are all
+"bad", so we want to say that:
+
+-------------
+information_if_bad(X) = number_of_descendants(X)  (WRONG)
+-------------
+
+But this is wrong because at step 1) a) we keep only the ancestors of
+the bad commit. So we get more information when a commit is marked as
+"bad", because we also know that the ancestors of the previous "bad"
+commit that are not ancestors of the new "bad" commit are not the
+first bad commit. We don't know if they are good or bad, but we know
+that they are not the first bad commit because they are not ancestor
+of the new "bad" commit.
+
+So when a commit is marked as "bad" we know we can remove all the
+commits in the graph except those that are ancestors of the new "bad"
+commit. This means that:
+
+-------------
+information_if_bad(X) = N - number_of_ancestors(X)  (TRUE)
+-------------
+
+where N is the number of commits in the (cleaned up) graph.
+
+So in the end this means that to find the best bisection commits we
+should maximize the function:
+
+-------------
+f(X) = min(number_of_ancestors(X), N - number_of_ancestors(X))
+-------------
+
+And this is nice because at step 2) we compute number_of_ancestors(X)
+and so at step 3) we compute f(X).
+
+Let's take the following graph as an example:
+
+-------------
+	    G-H-I-J
+	   /       \
+A-B-C-D-E-F         O
+	   \       /
+	    K-L-M-N
+-------------
+
+If we compute the following non optimal function on it:
+
+-------------
+g(X) = min(number_of_ancestors(X), number_of_descendants(X))
+-------------
+
+we get:
+
+-------------
+	    4 3 2 1
+	    G-H-I-J
+1 2 3 4 5 6/       \0
+A-B-C-D-E-F         O
+	   \       /
+	    K-L-M-N
+	    4 3 2 1
+-------------
+
+but with the algorithm used by git bisect we get:
+
+-------------
+	    7 7 6 5
+	    G-H-I-J
+1 2 3 4 5 6/       \0
+A-B-C-D-E-F         O
+	   \       /
+	    K-L-M-N
+	    7 7 6 5
+-------------
+
+So we chose G, H, K or L as the best bisection point, which is better
+than F. Because if for example L is bad, then we will know not only
+that L, M and N are bad but also that G, H, I and J are not the first
+bad commit (since we suppose that there is only one first bad commit
+and it must be an ancestor of L).
+
+So the current algorithm seems to be the best possible given what we
+initially supposed.
+
+Skip algorithm
+~~~~~~~~~~~~~~
+
+When some commits have been skipped (using "git bisect skip"), then
+the bisection algorithm is the same for step 1) to 3). But then we use
+roughly the following steps:
+
+6) sort the commit by decreasing associated value
+
+7) if the first commit has not been skipped, we can return it and stop
+here
+
+8) otherwise filter out all the skipped commits in the sorted list
+
+9) use a pseudo random number generator (PRNG) to generate a random
+number between 0 and 1
+
+10) multiply this random number with its square root to bias it toward
+0
+
+11) multiply the result by the number of commits in the filtered list
+to get an index into this list
+
+12) return the commit at the computed index
+
+Skip algorithm discussed
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+After step 7) (in the skip algorithm), we could check if the second
+commit has been skipped and return it if it is not the case. And in
+fact that was the algorithm we used from when "git bisect skip" was
+developed in Git version 1.5.4 (released on February 1st 2008) until
+Git version 1.6.4 (released July 29th 2009).
+
+But Ingo Molnar and H. Peter Anvin (another well known linux kernel
+developer) both complained that sometimes the best bisection points
+all happened to be in an area where all the commits are
+untestable. And in this case the user was asked to test many
+untestable commits, which could be very inefficient.
+
+Indeed untestable commits are often untestable because a breakage was
+introduced at one time, and that breakage was fixed only after many
+other commits were introduced.
+
+This breakage is of course most of the time unrelated to the breakage
+we are trying to locate in the commit graph. But it prevents us to
+know if the interesting "bad behavior" is present or not.
+
+So it is a fact that commits near an untestable commit have a high
+probability of being untestable themselves. And the best bisection
+commits are often found together too (due to the bisection algorithm).
+
+This is why it is a bad idea to just chose the next best unskipped
+bisection commit when the first one has been skipped.
+
+We found that most commits on the graph may give quite a lot of
+information when they are tested. And the commits that will not on
+average give a lot of information are the one near the good and bad
+commits.
+
+So using a PRNG with a bias to favor commits away from the good and
+bad commits looked like a good choice.
+
+One obvious improvement to this algorithm would be to look for a
+commit that has an associated value near the one of the best bisection
+commit, and that is on another branch, before using the PRNG. Because
+if such a commit exists, then it is not very likely to be untestable
+too, so it will probably give more information than a nearly randomly
+chosen one.
+
+Checking merge bases
+~~~~~~~~~~~~~~~~~~~~
+
+There is another tweak in the bisection algorithm that has not been
+described in the "bisection algorithm" above.
+
+We supposed in the previous examples that the "good" commits were
+ancestors of the "bad" commit. But this is not a requirement of "git
+bisect".
+
+Of course the "bad" commit cannot be an ancestor of a "good" commit,
+because the ancestors of the good commits are supposed to be
+"good". And all the "good" commits must be related to the bad commit.
+They cannot be on a branch that has no link with the branch of the
+"bad" commit. But it is possible for a good commit to be related to a
+bad commit and yet not be neither one of its ancestor nor one of its
+descendants.
+
+For example, there can be a "main" branch, and a "dev" branch that was
+forked of the main branch at a commit named "D" like this:
+
+-------------
+A-B-C-D-E-F-G  <--main
+       \
+	H-I-J  <--dev
+-------------
+
+The commit "D" is called a "merge base" for branch "main" and "dev"
+because it's the best common ancestor for these branches for a merge.
+
+Now let's suppose that commit J is bad and commit G is good and that
+we apply the bisection algorithm like it has been previously
+described.
+
+As described in step 1) b) of the bisection algorithm, we remove all
+the ancestors of the good commits because they are supposed to be good
+too.
+
+So we would be left with only:
+
+-------------
+H-I-J
+-------------
+
+But what happens if the first bad commit is "B" and if it has been
+fixed in the "main" branch by commit "F"?
+
+The result of such a bisection would be that we would find that H is
+the first bad commit, when in fact it's B. So that would be wrong!
+
+And yes it can happen in practice that people working on one branch
+are not aware that people working on another branch fixed a bug! It
+could also happen that F fixed more than one bug or that it is a
+revert of some big development effort that was not ready to be
+released.
+
+In fact development teams often maintain both a development branch and
+a maintenance branch, and it would be quite easy for them if "git
+bisect" just worked when they want to bisect a regression on the
+development branch that is not on the maintenance branch. They should
+be able to start bisecting using:
+
+-------------
+$ git bisect start dev main
+-------------
+
+To enable that additional nice feature, when a bisection is started
+and when some good commits are not ancestors of the bad commit, we
+first compute the merge bases between the bad and the good commits and
+we chose these merge bases as the first commits that will be checked
+out and tested.
+
+If it happens that one merge base is bad, then the bisection process
+is stopped with a message like:
+
+-------------
+The merge base BBBBBB is bad.
+This means the bug has been fixed between BBBBBB and [GGGGGG,...].
+-------------
+
+where BBBBBB is the sha1 hash of the bad merge base and [GGGGGG,...]
+is a comma separated list of the sha1 of the good commits.
+
+If some of the merge bases are skipped, then the bisection process
+continues, but the following message is printed for each skipped merge
+base:
+
+-------------
+Warning: the merge base between BBBBBB and [GGGGGG,...] must be skipped.
+So we cannot be sure the first bad commit is between MMMMMM and BBBBBB.
+We continue anyway.
+-------------
+
+where BBBBBB is the sha1 hash of the bad commit, MMMMMM is the sha1
+hash of the merge base that is skipped and [GGGGGG,...]  is a comma
+separated list of the sha1 of the good commits.
+
+So if there is no bad merge base, the bisection process continues as
+usual after this step.
+
+Best bisecting practices
+------------------------
+
+Using test suites and git bisect together
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you both have a test suite and use git bisect, then it becomes less
+important to check that all tests pass after each commit. Though of
+course it is probably a good idea to have some checks to avoid
+breaking too many things because it could make bisecting other bugs
+more difficult.
+
+You can focus your efforts to check at a few points (for example rc
+and beta releases) that all the T test cases pass for all the N
+configurations. And when some tests don't pass you can use "git
+bisect" (or better "git bisect run"). So you should perform roughly:
+
+-------------
+c * N * T + b * M * log2(M) tests
+-------------
+
+where c is the number of rounds of test (so a small constant) and b is
+the ratio of bug per commit (hopefully a small constant too).
+
+So of course it's much better as it's O(N * T) vs O(N * T * M) if
+you would test everything after each commit.
+
+This means that test suites are good to prevent some bugs from being
+committed and they are also quite good to tell you that you have some
+bugs. But they are not so good to tell you where some bugs have been
+introduced. To tell you that efficiently, git bisect is needed.
+
+The other nice thing with test suites, is that when you have one, you
+already know how to test for bad behavior. So you can use this
+knowledge to create a new test case for "git bisect" when it appears
+that there is a regression. So it will be easier to bisect the bug and
+fix it. And then you can add the test case you just created to your
+test suite.
+
+So if you know how to create test cases and how to bisect, you will be
+subject to a virtuous circle:
+
+more tests => easier to create tests => easier to bisect => more tests
+
+So test suites and "git bisect" are complementary tools that are very
+powerful and efficient when used together.
+
+Bisecting build failures
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can very easily automatically bisect broken builds using something
+like:
+
+-------------
+$ git bisect start BAD GOOD
+$ git bisect run make
+-------------
+
+Passing sh -c "some commands" to "git bisect run"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For example:
+
+-------------
+$ git bisect run sh -c "make || exit 125; ./my_app | grep 'good output'"
+-------------
+
+On the other hand if you do this often, then it can be worth having
+scripts to avoid too much typing.
+
+Finding performance regressions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here is an example script that comes slightly modified from a real
+world script used by Junio Hamano <<4>>.
+
+This script can be passed to "git bisect run" to find the commit that
+introduced a performance regression:
+
+-------------
+#!/bin/sh
+
+# Build errors are not what I am interested in.
+make my_app || exit 255
+
+# We are checking if it stops in a reasonable amount of time, so
+# let it run in the background...
+
+./my_app >log 2>&1 &
+
+# ... and grab its process ID.
+pid=$!
+
+# ... and then wait for sufficiently long.
+sleep $NORMAL_TIME
+
+# ... and then see if the process is still there.
+if kill -0 $pid
+then
+	# It is still running -- that is bad.
+	kill $pid; sleep 1; kill $pid;
+	exit 1
+else
+	# It has already finished (the $pid process was no more),
+	# and we are happy.
+	exit 0
+fi
+-------------
+
+Following general best practices
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is obviously a good idea not to have commits with changes that
+knowingly break things, even if some other commits later fix the
+breakage.
+
+It is also a good idea when using any VCS to have only one small
+logical change in each commit.
+
+The smaller the changes in your commit, the most effective "git
+bisect" will be. And you will probably need "git bisect" less in the
+first place, as small changes are easier to review even if they are
+only reviewed by the committer.
+
+Another good idea is to have good commit messages. They can be very
+helpful to understand why some changes were made.
+
+These general best practices are very helpful if you bisect often.
+
+Avoiding bug prone merges
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First merges by themselves can introduce some regressions even when
+the merge needs no source code conflict resolution. This is because a
+semantic change can happen in one branch while the other branch is not
+aware of it.
+
+For example one branch can change the semantic of a function while the
+other branch add more calls to the same function.
+
+This is made much worse if many files have to be fixed to resolve
+conflicts. That's why such merges are called "evil merges". They can
+make regressions very difficult to track down. It can even be
+misleading to know the first bad commit if it happens to be such a
+merge, because people might think that the bug comes from bad conflict
+resolution when it comes from a semantic change in one branch.
+
+Anyway "git rebase" can be used to linearize history. This can be used
+either to avoid merging in the first place. Or it can be used to
+bisect on a linear history instead of the non linear one, as this
+should give more information in case of a semantic change in one
+branch.
+
+Merges can be also made simpler by using smaller branches or by using
+many topic branches instead of only long version related branches.
+
+And testing can be done more often in special integration branches
+like linux-next for the linux kernel.
+
+Adapting your work-flow
+~~~~~~~~~~~~~~~~~~~~~~~
+
+A special work-flow to process regressions can give great results.
+
+Here is an example of a work-flow used by Andreas Ericsson:
+
+* write, in the test suite, a test script that exposes the regression
+* use "git bisect run" to find the commit that introduced it
+* fix the bug that is often made obvious by the previous step
+* commit both the fix and the test script (and if needed more tests)
+
+And here is what Andreas said about this work-flow <<5>>:
+
+_____________
+To give some hard figures, we used to have an average report-to-fix
+cycle of 142.6 hours (according to our somewhat weird bug-tracker
+which just measures wall-clock time). Since we moved to Git, we've
+lowered that to 16.2 hours. Primarily because we can stay on top of
+the bug fixing now, and because everyone's jockeying to get to fix
+bugs (we're quite proud of how lazy we are to let Git find the bugs
+for us). Each new release results in ~40% fewer bugs (almost certainly
+due to how we now feel about writing tests).
+_____________
+
+Clearly this work-flow uses the virtuous circle between test suites
+and "git bisect". In fact it makes it the standard procedure to deal
+with regression.
+
+In other messages Andreas says that they also use the "best practices"
+described above: small logical commits, topic branches, no evil
+merge,... These practices all improve the bisectability of the commit
+graph, by making it easier and more useful to bisect.
+
+So a good work-flow should be designed around the above points. That
+is making bisecting easier, more useful and standard.
+
+Involving QA people and if possible end users
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One nice about "git bisect" is that it is not only a developer
+tool. It can effectively be used by QA people or even end users (if
+they have access to the source code or if they can get access to all
+the builds).
+
+There was a discussion at one point on the linux kernel mailing list
+of whether it was ok to always ask end user to bisect, and very good
+points were made to support the point of view that it is ok.
+
+For example David Miller wrote <<6>>:
+
+_____________
+What people don't get is that this is a situation where the "end node
+principle" applies. When you have limited resources (here: developers)
+you don't push the bulk of the burden upon them. Instead you push
+things out to the resource you have a lot of, the end nodes (here:
+users), so that the situation actually scales.
+_____________
+
+This means that it is often "cheaper" if QA people or end users can do
+it.
+
+What is interesting too is that end users that are reporting bugs (or
+QA people that reproduced a bug) have access to the environment where
+the bug happens. So they can often more easily reproduce a
+regression. And if they can bisect, then more information will be
+extracted from the environment where the bug happens, which means that
+it will be easier to understand and then fix the bug.
+
+For open source projects it can be a good way to get more useful
+contributions from end users, and to introduce them to QA and
+development activities.
+
+Using complex scripts
+~~~~~~~~~~~~~~~~~~~~~
+
+In some cases like for kernel development it can be worth developing
+complex scripts to be able to fully automate bisecting.
+
+Here is what Ingo Molnar says about that <<7>>:
+
+_____________
+i have a fully automated bootup-hang bisection script. It is based on
+"git-bisect run". I run the script, it builds and boots kernels fully
+automatically, and when the bootup fails (the script notices that via
+the serial log, which it continuously watches - or via a timeout, if
+the system does not come up within 10 minutes it's a "bad" kernel),
+the script raises my attention via a beep and i power cycle the test
+box. (yeah, i should make use of a managed power outlet to 100%
+automate it)
+_____________
+
+Combining test suites, git bisect and other systems together
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We have seen that test suites an git bisect are very powerful when
+used together. It can be even more powerful if you can combine them
+with other systems.
+
+For example some test suites could be run automatically at night with
+some unusual (or even random) configurations. And if a regression is
+found by a test suite, then "git bisect" can be automatically
+launched, and its result can be emailed to the author of the first bad
+commit found by "git bisect", and perhaps other people too. And a new
+entry in the bug tracking system could be automatically created too.
+
+
+The future of bisecting
+-----------------------
+
+"git replace"
+~~~~~~~~~~~~~
+
+We saw earlier that "git bisect skip" is now using a PRNG to try to
+avoid areas in the commit graph where commits are untestable. The
+problem is that sometimes the first bad commit will be in an
+untestable area.
+
+To simplify the discussion we will suppose that the untestable area is
+a simple string of commits and that it was created by a breakage
+introduced by one commit (let's call it BBC for bisect breaking
+commit) and later fixed by another one (let's call it BFC for bisect
+fixing commit).
+
+For example:
+
+-------------
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z-...
+-------------
+
+where we know that Y is good and BFC is bad, and where BBC and X1 to
+X6 are untestable.
+
+In this case if you are bisecting manually, what you can do is create
+a special branch that starts just before the BBC. The first commit in
+this branch should be the BBC with the BFC squashed into it. And the
+other commits in the branch should be the commits between BBC and BFC
+rebased on the first commit of the branch and then the commit after
+BFC also rebased on.
+
+For example:
+
+-------------
+      (BBC+BFC)-X1'-X2'-X3'-X4'-X5'-X6'-Z'
+     /
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z-...
+-------------
+
+where commits quoted with ' have been rebased.
+
+You can easily create such a branch with Git using interactive rebase.
+
+For example using:
+
+-------------
+$ git rebase -i Y Z
+-------------
+
+and then moving BFC after BBC and squashing it.
+
+After that you can start bisecting as usual in the new branch and you
+should eventually find the first bad commit.
+
+For example:
+
+-------------
+$ git bisect start Z' Y
+-------------
+
+If you are using "git bisect run", you can use the same manual fix up
+as above, and then start another "git bisect run" in the special
+branch. Or as the "git bisect" man page says, the script passed to
+"git bisect run" can apply a patch before it compiles and test the
+software <<8>>. The patch should turn a current untestable commits
+into a testable one. So the testing will result in "good" or "bad" and
+"git bisect" will be able to find the first bad commit. And the script
+should not forget to remove the patch once the testing is done before
+exiting from the script.
+
+(Note that instead of a patch you can use "git cherry-pick BFC" to
+apply the fix, and in this case you should use "git reset --hard
+HEAD^" to revert the cherry-pick after testing and before returning
+from the script.)
+
+But the above ways to work around untestable areas are a little bit
+clunky. Using special branches is nice because these branches can be
+shared by developers like usual branches, but the risk is that people
+will get many such branches. And it disrupts the normal "git bisect"
+work-flow. So, if you want to use "git bisect run" completely
+automatically, you have to add special code in your script to restart
+bisection in the special branches.
+
+Anyway one can notice in the above special branch example that the Z'
+and Z commits should point to the same source code state (the same
+"tree" in git parlance). That's because Z' result from applying the
+same changes as Z just in a slightly different order.
+
+So if we could just "replace" Z by Z' when we bisect, then we would
+not need to add anything to a script. It would just work for anyone in
+the project sharing the special branches and the replacements.
+
+With the example above that would give:
+
+-------------
+      (BBC+BFC)-X1'-X2'-X3'-X4'-X5'-X6'-Z'-...
+     /
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z
+-------------
+
+That's why the "git replace" command was created. Technically it
+stores replacements "refs" in the "refs/replace/" hierarchy. These
+"refs" are like branches (that are stored in "refs/heads/") or tags
+(that are stored in "refs/tags"), and that means that they can
+automatically be shared like branches or tags among developers.
+
+"git replace" is a very powerful mechanism. It can be used to fix
+commits in already released history, for example to change the commit
+message or the author. And it can also be used instead of git "grafts"
+to link a repository with another old repository.
+
+In fact it's this last feature that "sold" it to the Git community, so
+it is now in the "master" branch of Git's Git repository and it should
+be released in Git 1.6.5 in October or November 2009.
+
+One problem with "git replace" is that currently it stores all the
+replacements refs in "refs/replace/", but it would be perhaps better
+if the replacement refs that are useful only for bisecting would be in
+"refs/replace/bisect/". This way the replacement refs could be used
+only for bisecting, while other refs directly in "refs/replace/" would
+be used nearly all the time.
+
+Bisecting sporadic bugs
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Another possible improvement to "git bisect" would be to optionally
+add some redundancy to the tests performed so that it would be more
+reliable when tracking sporadic bugs.
+
+This has been requested by some kernel developers because some bugs
+called sporadic bugs do not appear in all the kernel builds because
+they are very dependent on the compiler output.
+
+The idea is that every 3 test for example, "git bisect" could ask the
+user to test a commit that has already been found to be "good" or
+"bad" (because one of its descendants or one of its ancestors has been
+found to be "good" or "bad" respectively). If it happens that a commit
+has been previously incorrectly classified then the bisection can be
+aborted early, hopefully before too many mistakes have been made. Then
+the user will have to look at what happened and then restart the
+bisection using a fixed bisect log.
+
+There is already a project called BBChop created by Ealdwulf Wuffinga
+on Github that does something like that using Bayesian Search Theory
+<<9>>:
+
+_____________
+BBChop is like 'git bisect' (or equivalent), but works when your bug
+is intermittent. That is, it works in the presence of false negatives
+(when a version happens to work this time even though it contains the
+bug). It assumes that there are no false positives (in principle, the
+same approach would work, but adding it may be non-trivial).
+_____________
+
+But BBChop is independent of any VCS and it would be easier for Git
+users to have something integrated in Git.
+
+Conclusion
+----------
+
+We have seen that regressions are an important problem, and that "git
+bisect" has nice features that complement very well practices and
+other tools, especially test suites, that are generally used to fight
+regressions. But it might be needed to change some work-flows and
+(bad) habits to get the most out of it.
+
+Some improvements to the algorithms inside "git bisect" are possible
+and some new features could help in some cases, but overall "git
+bisect" works already very well, is used a lot, and is already very
+useful. To back up that last claim, let's give the final word to Ingo
+Molnar when he was asked by the author how much time does he think
+"git bisect" saves him when he uses it:
+
+_____________
+a _lot_.
+
+About ten years ago did i do my first 'bisection' of a Linux patch
+queue. That was prior the Git (and even prior the BitKeeper) days. I
+literally days spent sorting out patches, creating what in essence
+were standalone commits that i guessed to be related to that bug.
+
+It was a tool of absolute last resort. I'd rather spend days looking
+at printk output than do a manual 'patch bisection'.
+
+With Git bisect it's a breeze: in the best case i can get a ~15 step
+kernel bisection done in 20-30 minutes, in an automated way. Even with
+manual help or when bisecting multiple, overlapping bugs, it's rarely
+more than an hour.
+
+In fact it's invaluable because there are bugs i would never even
+_try_ to debug if it wasn't for git bisect. In the past there were bug
+patterns that were immediately hopeless for me to debug - at best i
+could send the crash/bug signature to lkml and hope that someone else
+can think of something.
+
+And even if a bisection fails today it tells us something valuable
+about the bug: that it's non-deterministic - timing or kernel image
+layout dependent.
+
+So git bisect is unconditional goodness - and feel free to quote that
+;-)

+
+This command uses a binary search algorithm to find which commit in
+your project's history introduced a bug. You use it by first telling
+it a "bad" commit that is known to contain the bug, and a "good"
+commit that is known to be before the bug was introduced. Then `git
+bisect` picks a commit between those two endpoints and asks you
+whether the selected commit is "good" or "bad". It continues narrowing
+down the range until it finds the exact commit that introduced the
+change.
 
-This command uses 'git-rev-list --bisect' option to help drive
-the binary search process to find which change introduced a bug,
-given an old "good" commit object name and a later "bad" commit
-object name.
+Basic bisect commands: start, bad, good
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-The way you use it is:
+As an example, suppose you are trying to find the commit that broke a
+feature that was known to work in version `v2.6.13-rc2` of your
+project. You start a bisect session as follows:
 
 ------------------------------------------------
 $ git bisect start
-$ git bisect bad			# Current version is bad
-$ git bisect good v2.6.13-rc2		# v2.6.13-rc2 was the last version
-					# tested that was good
+$ git bisect bad                 # Current version is bad
+$ git bisect good v2.6.13-rc2    # v2.6.13-rc2 is known to be good
+------------------------------------------------
+
+Once you have specified at least one bad and one good commit, `git
+bisect` selects a commit in the middle of that range of history,
+checks it out, and outputs something similar to the following:
+
+------------------------------------------------
+Bisecting: 675 revisions left to test after this (roughly 10 steps)
 ------------------------------------------------
 
-When you give at least one bad and one good versions, it will
-bisect the revision tree and say something like:
+You should now compile the checked-out version and test it. If that
+version works correctly, type
 
 ------------------------------------------------
-Bisecting: 675 revisions left to test after this
+$ git bisect good
 ------------------------------------------------
 
-and check out the state in the middle. Now, compile that kernel, and boot
-it. Now, let's say that this booted kernel works fine, then just do
+If that version is broken, type
 
 ------------------------------------------------
-$ git bisect good			# this one is good
+$ git bisect bad
 ------------------------------------------------
 
-which will now say
+Then `git bisect` will respond with something like
 
 ------------------------------------------------
-Bisecting: 337 revisions left to test after this
+Bisecting: 337 revisions left to test after this (roughly 9 steps)
 ------------------------------------------------
 
-and you continue along, compiling that one, testing it, and depending on
-whether it is good or bad, you say "git bisect good" or "git bisect bad",
-and ask for the next bisection.
+Keep repeating the process: compile the tree, test it, and depending
+on whether it is good or bad run `git bisect good` or `git bisect bad`
+to ask for the next commit that needs testing.
+
+Eventually there will be no more revisions left to inspect, and the
+command will print out a description of the first bad commit. The
+reference `refs/bisect/bad` will be left pointing at that commit.
+
 
-Until you have no more left, and you'll have been left with the first bad
-kernel rev in "refs/bisect/bad".
+Bisect reset
+~~~~~~~~~~~~
 
-Oh, and then after you want to reset to the original head, do a
+After a bisect session, to clean up the bisection state and return to
+the original HEAD, issue the following command:
 
 ------------------------------------------------
 $ git bisect reset
 ------------------------------------------------
 
-to get back to the master branch, instead of being in one of the bisection
-branches ("git bisect start" will do that for you too, actually: it will
-reset the bisection state, and before it does that it checks that you're
-not using some old bisection branch).
+By default, this will return your tree to the commit that was checked
+out before `git bisect start`.  (A new `git bisect start` will also do
+that, as it cleans up the old bisection state.)
 
-During the bisection process, you can say
+With an optional argument, you can return to a different commit
+instead:
+
+------------------------------------------------
+$ git bisect reset <commit>
+------------------------------------------------
+
+For example, `git bisect reset bisect/bad` will check out the first
+bad revision, while `git bisect reset HEAD` will leave you on the
+current bisection commit and avoid switching commits at all.
+
+
+Bisect visualize
+~~~~~~~~~~~~~~~~
+
+To see the currently remaining suspects in 'gitk', issue the following
+command during the bisection process:
 
 ------------
 $ git bisect visualize
 ------------
 
-to see the currently remaining suspects in `gitk`.
+`view` may also be used as a synonym for `visualize`.
 
-The good/bad input is logged, and `git bisect
-log` shows what you have done so far.  You can truncate its
-output somewhere and save it in a file, and run
+If the 'DISPLAY' environment variable is not set, 'git log' is used
+instead.  You can also give command-line options such as `-p` and
+`--stat`.
 
 ------------
+$ git bisect view --stat
+------------
+
+Bisect log and bisect replay
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After having marked revisions as good or bad, issue the following
+command to show what has been done so far:
+
+------------
+$ git bisect log
+------------
+
+If you discover that you made a mistake in specifying the status of a
+revision, you can save the output of this command to a file, edit it to
+remove the incorrect entries, and then issue the following commands to
+return to a corrected state:
+
+------------
+$ git bisect reset
 $ git bisect replay that-file
 ------------
 
-if you find later you made a mistake telling good/bad about a
-revision.
+Avoiding testing a commit
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If, in the middle of a bisect session, you know that the suggested
+revision is not a good one to test (e.g. it fails to build and you
+know that the failure does not have anything to do with the bug you
+are chasing), you can manually select a nearby commit and test that
+one instead.
 
-If in a middle of bisect session, you know what the bisect
-suggested to try next is not a good one to test (e.g. the change
-the commit introduces is known not to work in your environment
-and you know it does not have anything to do with the bug you
-are chasing), you may want to find a near-by commit and try that
-instead.  It goes something like this:
+For example:
 
 ------------
-$ git bisect good/bad			# previous round was good/bad.
-Bisecting: 337 revisions left to test after this
+$ git bisect good/bad			# previous round was good or bad.
+Bisecting: 337 revisions left to test after this (roughly 9 steps)
 $ git bisect visualize			# oops, that is uninteresting.
-$ git reset --hard HEAD~3		# try 3 revs before what
+$ git reset --hard HEAD~3		# try 3 revisions before what
 					# was suggested
 ------------
 
-Then compile and test the one you chose to try.  After that,
-tell bisect what the result was as usual.
+Then compile and test the chosen revision, and afterwards mark
+the revision as good or bad in the usual manner.
+
+Bisect skip
+~~~~~~~~~~~~
+
+Instead of choosing a nearby commit by yourself, you can ask Git to do
+it for you by issuing the command:
+
+------------
+$ git bisect skip                 # Current version cannot be tested
+------------
+
+However, if you skip a commit adjacent to the one you are looking for,
+Git will be unable to tell exactly which of those commits was the
+first bad one.
+
+You can also skip a range of commits, instead of just one commit,
+using range notation. For example:
+
+------------
+$ git bisect skip v2.5..v2.6
+------------
+
+This tells the bisect process that no commit after `v2.5`, up to and
+including `v2.6`, should be tested.
 
-You can further cut down the number of trials if you know what
-part of the tree is involved in the problem you are tracking
-down, by giving paths parameters when you say `bisect start`,
-like this:
+Note that if you also want to skip the first commit of the range you
+would issue the command:
 
 ------------
-$ git bisect start arch/i386 include/asm-i386
+$ git bisect skip v2.5 v2.5..v2.6
 ------------
 
+This tells the bisect process that the commits between `v2.5` and
+`v2.6` (inclusive) should be skipped.

+Cutting down bisection by giving more parameters to bisect start
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can further cut down the number of trials, if you know what part of
+the tree is involved in the problem you are tracking down, by specifying
+path parameters when issuing the `bisect start` command:
+
+------------
+$ git bisect start -- arch/i386 include/asm-i386
+------------
+
+If you know beforehand more than one good commit, you can narrow the
+bisect space down by specifying all of the good commits immediately after
+the bad commit when issuing the `bisect start` command:
+
+------------
+$ git bisect start v2.6.20-rc6 v2.6.20-rc4 v2.6.20-rc1 --
+                   # v2.6.20-rc6 is bad
+                   # v2.6.20-rc4 and v2.6.20-rc1 are good
+------------
+
+Bisect run
+~~~~~~~~~~
+
+If you have a script that can tell if the current source code is good
+or bad, you can bisect by issuing the command:
+
+------------
+$ git bisect run my_script arguments
+------------
+
+Note that the script (`my_script` in the above example) should exit
+with code 0 if the current source code is good/old, and exit with a
+code between 1 and 127 (inclusive), except 125, if the current source
+code is bad/new.
+
+Any other exit code will abort the bisect process. It should be noted
+that a program that terminates via `exit(-1)` leaves $? = 255, (see the
+exit(3) manual page), as the value is chopped with `& 0377`.
+
+The special exit code 125 should be used when the current source code
+cannot be tested. If the script exits with this code, the current
+revision will be skipped (see `git bisect skip` above). 125 was chosen
+as the highest sensible value to use for this purpose, because 126 and 127
+are used by POSIX shells to signal specific error status (127 is for
+command not found, 126 is for command found but not executable---these
+details do not matter, as they are normal errors in the script, as far as
+`bisect run` is concerned).
+
+You may often find that during a bisect session you want to have
+temporary modifications (e.g. s/#define DEBUG 0/#define DEBUG 1/ in a
+header file, or "revision that does not have this commit needs this
+patch applied to work around another problem this bisection is not
+interested in") applied to the revision being tested.
+
+To cope with such a situation, after the inner 'git bisect' finds the
+next revision to test, the script can apply the patch
+before compiling, run the real test, and afterwards decide if the
+revision (possibly with the needed patch) passed the test and then
+rewind the tree to the pristine state.  Finally the script should exit
+with the status of the real test to let the `git bisect run` command loop
+determine the eventual outcome of the bisect session.
+
+OPTIONS
+-------
+--no-checkout::
++
+Do not checkout the new working tree at each iteration of the bisection
+process. Instead just update a special reference named 'BISECT_HEAD' to make
+it point to the commit that should be tested.
++
+This option may be useful when the test you would perform in each step
+does not require a checked out tree.
++
+If the repository is bare, `--no-checkout` is assumed.
+
+EXAMPLES
+--------
+
+* Automatically bisect a broken build between v1.2 and HEAD:
++
+------------
+$ git bisect start HEAD v1.2 --      # HEAD is bad, v1.2 is good
+$ git bisect run make                # "make" builds the app
+$ git bisect reset                   # quit the bisect session
+------------
+
+* Automatically bisect a test failure between origin and HEAD:
++
+------------
+$ git bisect start HEAD origin --    # HEAD is bad, origin is good
+$ git bisect run make test           # "make test" builds and tests
+$ git bisect reset                   # quit the bisect session
+------------
+
+* Automatically bisect a broken test case:
++
+------------
+$ cat ~/test.sh
+#!/bin/sh
+make || exit 125                     # this skips broken builds
+~/check_test_case.sh                 # does the test case pass?
+$ git bisect start HEAD HEAD~10 --   # culprit is among the last 10
+$ git bisect run ~/test.sh
+$ git bisect reset                   # quit the bisect session
+------------
++
+Here we use a `test.sh` custom script. In this script, if `make`
+fails, we skip the current commit.
+`check_test_case.sh` should `exit 0` if the test case passes,
+and `exit 1` otherwise.
++
+It is safer if both `test.sh` and `check_test_case.sh` are
+outside the repository to prevent interactions between the bisect,
+make and test processes and the scripts.
+
+* Automatically bisect with temporary modifications (hot-fix):
++
+------------
+$ cat ~/test.sh
+#!/bin/sh
+
+# tweak the working tree by merging the hot-fix branch
+# and then attempt a build
+if	git merge --no-commit hot-fix &&
+	make
+then
+	# run project specific test and report its status
+	~/check_test_case.sh
+	status=$?
+else
+	# tell the caller this is untestable
+	status=125
+fi
+
+# undo the tweak to allow clean flipping to the next commit
+git reset --hard
+
+# return control
+exit $status
+------------
++
+This applies modifications from a hot-fix branch before each test run,
+e.g. in case your build or test environment changed so that older
+revisions may need a fix which newer ones have already. (Make sure the
+hot-fix branch is based off a commit which is contained in all revisions
+which you are bisecting, so that the merge does not pull in too much, or
+use `git cherry-pick` instead of `git merge`.)
+
+* Automatically bisect a broken test case:
++
+------------
+$ git bisect start HEAD HEAD~10 --   # culprit is among the last 10
+$ git bisect run sh -c "make || exit 125; ~/check_test_case.sh"
+$ git bisect reset                   # quit the bisect session
+------------
++
+This shows that you can do without a run script if you write the test
+on a single line.
+
+* Locate a good region of the object graph in a damaged repository
++
+------------
+$ git bisect start HEAD <known-good-commit> [ <boundary-commit> ... ] --no-checkout
+$ git bisect run sh -c '
+	GOOD=$(git for-each-ref "--format=%(objectname)" refs/bisect/good-*) &&
+	git rev-list --objects BISECT_HEAD --not $GOOD >tmp.$$ &&
+	git pack-objects --stdout >/dev/null <tmp.$$
+	rc=$?
+	rm -f tmp.$$
+	test $rc = 0'
+
+$ git bisect reset                   # quit the bisect session
+------------
++
+In this case, when 'git bisect run' finishes, bisect/bad will refer to a commit that
+has at least one parent whose reachable graph is fully traversable in the sense
+required by 'git pack objects'.

 DESCRIPTION
 -----------
-With no arguments given a list of existing branches
-will be shown, the current branch will be highlighted with an asterisk.
-Option `-r` causes the remote-tracking branches to be listed,
-and option `-a` shows both.
 
-In its second form, a new branch named <branchname> will be created.
-It will start out with a head equal to the one given as <start-point>.
-If no <start-point> is given, the branch will be created with a head
-equal to that of the currently checked out branch.
-
-With a '-m' or '-M' option, <oldbranch> will be renamed to <newbranch>.
+If `--list` is given, or if there are no non-option arguments, existing
+branches are listed; the current branch will be highlighted with an
+asterisk.  Option `-r` causes the remote-tracking branches to be listed,
+and option `-a` shows both local and remote branches. If a `<pattern>`
+is given, it is used as a shell wildcard to restrict the output to
+matching branches. If multiple patterns are given, a branch is shown if
+it matches any of the patterns.  Note that when providing a
+`<pattern>`, you must use `--list`; otherwise the command is interpreted
+as branch creation.
+
+With `--contains`, shows only the branches that contain the named commit
+(in other words, the branches whose tip commits are descendants of the
+named commit).  With `--merged`, only branches merged into the named
+commit (i.e. the branches whose tip commits are reachable from the named
+commit) will be listed.  With `--no-merged` only branches not merged into
+the named commit will be listed.  If the <commit> argument is missing it
+defaults to 'HEAD' (i.e. the tip of the current branch).
+
+The command's second form creates a new branch head named <branchname>
+which points to the current 'HEAD', or <start-point> if given.
+
+Note that this will create the new branch, but it will not switch the
+working tree to it; use "git checkout <newbranch>" to switch to the
+new branch.
+
+When a local branch is started off a remote-tracking branch, Git sets up the
+branch (specifically the `branch.<name>.remote` and `branch.<name>.merge`
+configuration entries) so that 'git pull' will appropriately merge from
+the remote-tracking branch. This behavior may be changed via the global
+`branch.autoSetupMerge` configuration flag. That setting can be
+overridden by using the `--track` and `--no-track` options, and
+changed later using `git branch --set-upstream-to`.
+
+With a `-m` or `-M` option, <oldbranch> will be renamed to <newbranch>.
 If <oldbranch> had a corresponding reflog, it is renamed to match
 <newbranch>, and a reflog entry is created to remember the branch

 OPTIONS
 -------
 -d::
-	Delete a branch. The branch must be fully merged.
+--delete::
+	Delete a branch. The branch must be fully merged in its
+	upstream branch, or in `HEAD` if no upstream was set with
+	`--track` or `--set-upstream`.
 
 -D::
-	Delete a branch irrespective of its index status.
+	Shortcut for `--delete --force`.
 
 -l::
-	Create the branch's ref log.  This activates recording of
-	all changes to made the branch ref, enabling use of date
-	based sha1 expressions such as "<branchname>@{yesterday}".
+--create-reflog::
+	Create the branch's reflog.  This activates recording of
+	all changes made to the branch ref, enabling use of date
+	based sha1 expressions such as "<branchname>@\{yesterday}".
+	Note that in non-bare repositories, reflogs are usually
+	enabled by default by the `core.logallrefupdates` config option.
 
 -f::
-	Force the creation of a new branch even if it means deleting
-	a branch that already exists with the same name.
+--force::
+	Reset <branchname> to <startpoint> if <branchname> exists
+	already. Without `-f` 'git branch' refuses to change an existing branch.
+	In combination with `-d` (or `--delete`), allow deleting the
+	branch irrespective of its merged status. In combination with
+	`-m` (or `--move`), allow renaming the branch even if the new
+	branch name already exists.
 
 -m::
+--move::
 	Move/rename a branch and the corresponding reflog.
 
 -M::
-	Move/rename a branch even if the new branchname already exists.
+	Shortcut for `--move --force`.
 
---color::
-	Color branches to highlight current, local, and remote branches.
+--color[=<when>]::
+	Color branches to highlight current, local, and
+	remote-tracking branches.
+	The value must be always (the default), never, or auto.
 
 --no-color::
 	Turn off branch colors, even when the configuration file gives the
 	default to color output.
+	Same as `--color=never`.
+
+--column[=<options>]::
+--no-column::
+	Display branch listing in columns. See configuration variable
+	column.branch for option syntax.`--column` and `--no-column`
+	without options are equivalent to 'always' and 'never' respectively.
++
+This option is only applicable in non-verbose mode.
 
 -r::
+--remotes::
 	List or delete (if used with -d) the remote-tracking branches.
 
 -a::
+--all::
 	List both remote-tracking branches and local branches.
 
+--list::
+	Activate the list mode. `git branch <pattern>` would try to create a branch,
+	use `git branch --list <pattern>` to list matching branches.
+
 -v::
-	Show sha1 and commit subject line for each head.
+-vv::
+--verbose::
+	When in list mode,
+	show sha1 and commit subject line for each head, along with
+	relationship to upstream branch (if any). If given twice, print
+	the name of the upstream branch, as well (see also `git remote
+	show <remote>`).
+
+-q::
+--quiet::
+	Be more quiet when creating or deleting a branch, suppressing
+	non-error messages.
 
 --abbrev=<length>::
-	Alter minimum display length for sha1 in output listing,
-	default value is 7.
+	Alter the sha1's minimum display length in the output listing.
+	The default value is 7 and can be overridden by the `core.abbrev`
+	config option.
 
 --no-abbrev::
-	Display the full sha1s in output listing rather than abbreviating them.
+	Display the full sha1s in the output listing rather than abbreviating them.
+
+-t::
+--track::
+	When creating a new branch, set up `branch.<name>.remote` and
+	`branch.<name>.merge` configuration entries to mark the
+	start-point branch as "upstream" from the new branch. This
+	configuration will tell git to show the relationship between the
+	two branches in `git status` and `git branch -v`. Furthermore,
+	it directs `git pull` without arguments to pull from the
+	upstream when the new branch is checked out.
++
+This behavior is the default when the start point is a remote-tracking branch.
+Set the branch.autoSetupMerge configuration variable to `false` if you
+want `git checkout` and `git branch` to always behave as if '--no-track'
+were given. Set it to `always` if you want this behavior when the
+start-point is either a local or remote-tracking branch.
+
+--no-track::
+	Do not set up "upstream" configuration, even if the
+	branch.autoSetupMerge configuration variable is true.
+
+--set-upstream::
+	If specified branch does not exist yet or if `--force` has been
+	given, acts exactly like `--track`. Otherwise sets up configuration
+	like `--track` would when creating the branch, except that where
+	branch points to is not changed.
+
+-u <upstream>::
+--set-upstream-to=<upstream>::
+	Set up <branchname>'s tracking information so <upstream> is
+	considered <branchname>'s upstream branch. If no <branchname>
+	is specified, then it defaults to the current branch.
+
+--unset-upstream::
+	Remove the upstream information for <branchname>. If no branch
+	is specified it defaults to the current branch.
+
+--edit-description::
+	Open an editor and edit the text to explain what the branch is
+	for, to be used by various other commands (e.g. `format-patch`,
+	`request-pull`, and `merge` (if enabled)). Multi-line explanations
+	may be used.
+
+--contains [<commit>]::
+	Only list branches which contain the specified commit (HEAD
+	if not specified). Implies `--list`.

+--merged [<commit>]::
+	Only list branches whose tips are reachable from the

+	for storage in the repository, then prints the names of all
+	defined references. If a list of references is given, only
+	references matching those in the list are printed. This command is
+	really plumbing, intended to be called only by 'git fetch'.
+
+<git-rev-list-args>::
+	A list of arguments, acceptable to 'git rev-parse' and
+	'git rev-list' (and containing a named ref, see SPECIFYING REFERENCES
+	below), that specifies the specific objects and references
+	to transport.  For example, `master~10..master` causes the
+	current master reference to be packaged along with all objects
+	added since its 10th ancestor commit.  There is no explicit
+	limit to the number of references and objects that may be
+	packaged.
+
+
+[<refname>...]::
+	A list of references used to limit the references reported as
+	available. This is principally of use to 'git fetch', which
+	expects to receive only those references asked for and not
+	necessarily everything in the pack (in this case, 'git bundle' acts
+	like 'git fetch-pack').

 EXAMPLE
 -------
 
-Assume two repositories exist as R1 on machine A, and R2 on machine B.
+Assume you want to transfer the history from a repository R1 on machine A
+to another repository R2 on machine B.
 For whatever reason, direct connection between A and B is not allowed,
-but we can move data from A to B via some mechanism (CD, email, etc).
-We want to update R2 with developments made on branch master in R1.
-We set a tag in R1 (lastR2bundle) after the previous such transport,
-and move it afterwards to help build the bundle.
+but we can move data from A to B via some mechanism (CD, email, etc.).
+We want to update R2 with development made on the branch master in R1.
+
+To bootstrap the process, you can first create a bundle that does not have
+any basis. You can use a tag to remember up to what commit you last
+processed, in order to make it easy to later update the other repository
+with an incremental bundle:
+
+----------------
+machineA$ cd R1
+machineA$ git bundle create file.bundle master
+machineA$ git tag -f lastR2bundle master
+----------------
+
+Then you transfer file.bundle to the target machine B. Because this
+bundle does not require any existing object to be extracted, you can
+create a new repository on machine B by cloning from it:
+
+----------------
+machineB$ git clone -b master /home/me/tmp/file.bundle R2
+----------------
+
+This will define a remote called "origin" in the resulting repository that
+lets you fetch and pull from the bundle. The $GIT_DIR/config file in R2 will
+have an entry like this:
+
+------------------------
+[remote "origin"]
+    url = /home/me/tmp/file.bundle
+    fetch = refs/heads/*:refs/remotes/origin/*
+------------------------
 
-in R1 on A:
-$ git-bundle create mybundle master ^lastR2bundle
-$ git tag -f lastR2bundle master
+To update the resulting mine.git repository, you can fetch or pull after
+replacing the bundle stored at /home/me/tmp/file.bundle with incremental
+updates.
 
-(move mybundle from A to B by some mechanism)
+After working some more in the original repository, you can create an
+incremental bundle to update the other repository:
 
-in R2 on B:
-$ git-bundle verify mybundle
-$ git-fetch mybundle  refspec
+----------------
+machineA$ cd R1
+machineA$ git bundle create file.bundle lastR2bundle..master
+machineA$ git tag -f lastR2bundle master
+----------------
 
-where refspec is refInBundle:localRef
+You then transfer the bundle to the other machine to replace
+/home/me/tmp/file.bundle, and pull from it.
 
+----------------
+machineB$ cd R2
+machineB$ git pull
+----------------
 
-Also, with something like this in your config:
+If you know up to what commit the intended recipient repository should
+have the necessary objects, you can use that knowledge to specify the
+basis, giving a cut-off point to limit the revisions and objects that go
+in the resulting bundle. The previous example used the lastR2bundle tag
+for this purpose, but you can use any other options that you would give to
+the linkgit:git-log[1] command. Here are more examples:
 
-[remote "bundle"]
-    url = /home/me/tmp/file.bdl
-    fetch = refs/heads/*:refs/remotes/origin/*
+You can use a tag that is present in both:
+
+----------------
+$ git bundle create mybundle v1.0.0..master
+----------------
+
+You can use a basis based on time:
+
+----------------
+$ git bundle create mybundle --since=10.days master
+----------------
+
+You can use the number of commits:
+
+----------------
+$ git bundle create mybundle -10 master
+----------------
+
+You can run `git-bundle verify` to see if you can extract from a bundle
+that was created with a basis:
+
+----------------
+$ git bundle verify mybundle
+----------------
+
+This will list what commits you must have in order to extract from the
+bundle and will error out if you do not have them.
 
-You can first sneakernet the bundle file to ~/tmp/file.bdl and
-then these commands:
+A bundle from a recipient repository's point of view is just like a
+regular repository which it fetches or pulls from. You can, for example, map
+references when fetching:
 
-$ git ls-remote bundle
-$ git fetch bundle
-$ git pull bundle
+----------------
+$ git fetch mybundle master:localRef
+----------------
 
-would treat it as if it is talking with a remote side over the
-network.
+You can also see what references it offers:

 SYNOPSIS

-'git-cat-file' [-t | -s | -e | -p | <type>] <object>
+[verse]
+'git cat-file' (-t [--allow-unknown-type]| -s [--allow-unknown-type]| -e | -p | <type> | --textconv ) <object>
+'git cat-file' (--batch | --batch-check) [--follow-symlinks] < <list-of-objects>
 
 DESCRIPTION
 -----------
-Provides content or type of objects in the repository. The type
-is required unless '-t' or '-p' is used to find the object type,
-or '-s' is used to find the object size.
+In its first form, the command provides the content or the type of an object in
+the repository. The type is required unless '-t' or '-p' is used to find the
+object type, or '-s' is used to find the object size, or '--textconv' is used
+(which implies type "blob").
+
+In the second form, a list of objects (separated by linefeeds) is provided on
+stdin, and the SHA-1, type, and size of each object is printed on stdout.

+
+--batch-all-objects::
+	Instead of reading a list of objects on stdin, perform the
+	requested batch operation on all objects in the repository and
+	any alternate object stores (not just reachable objects).
+	Requires `--batch` or `--batch-check` be specified. Note that
+	the objects are visited in order sorted by their hashes.
+
+--buffer::
+	Normally batch output is flushed after each object is output, so
+	that a process can interactively read and write from
+	`cat-file`. With this option, the output uses normal stdio
+	buffering; this is much more efficient when invoking
+	`--batch-check` on a large number of objects.
+
+--allow-unknown-type::
+	Allow -s or -t to query broken/corrupt objects of unknown type.
+
+--follow-symlinks::
+	With --batch or --batch-check, follow symlinks inside the
+	repository when requesting objects with extended SHA-1
+	expressions of the form tree-ish:path-in-tree.  Instead of
+	providing output about the link itself, provide output about
+	the linked-to object.  If a symlink points outside the
+	tree-ish (e.g. a link to /foo or a root-level link to ../foo),
+	the portion of the link which is outside the tree will be
+	printed.
++
+This option does not (currently) work correctly when an object in the
+index is specified (e.g. `:link` instead of `HEAD:link`) rather than
+one in the tree.
++
+This option cannot (currently) be used unless `--batch` or
+`--batch-check` is used.
++
+For example, consider a git repository containing:
++
+--
+	f: a file containing "hello\n"
+	link: a symlink to f
+	dir/link: a symlink to ../f
+	plink: a symlink to ../f
+	alink: a symlink to /etc/passwd
+--
++
+For a regular file `f`, `echo HEAD:f | git cat-file --batch` would print
++
+--
+	ce013625030ba8dba906f756967f9e9ca394464a blob 6
+--
++
+And `echo HEAD:link | git cat-file --batch --follow-symlinks` would
+print the same thing, as would `HEAD:dir/link`, as they both point at
+`HEAD:f`.
++
+Without `--follow-symlinks`, these would print data about the symlink
+itself.  In the case of `HEAD:link`, you would see
++
+--
+	4d1ae35ba2c8ec712fa2a379db44ad639ca277bd blob 1
+--
++
+Both `plink` and `alink` point outside the tree, so they would
+respectively print:

+	symlink 4

+BATCH OUTPUT
+------------
 
-Author
-------
-Written by Linus Torvalds <torvalds@osdl.org>
+If `--batch` or `--batch-check` is given, `cat-file` will read objects
+from stdin, one per line, and print information about them. By default,
+the whole line is considered as an object, as if it were fed to
+linkgit:git-rev-parse[1].
+
+You can specify the information shown for each object by using a custom
+`<format>`. The `<format>` is copied literally to stdout for each
+object, with placeholders of the form `%(atom)` expanded, followed by a
+newline. The available atoms are:
+
+`objectname`::
+	The 40-hex object name of the object.
+
+`objecttype`::
+	The type of of the object (the same as `cat-file -t` reports).
+
+`objectsize`::
+	The size, in bytes, of the object (the same as `cat-file -s`
+	reports).
+
+`objectsize:disk`::
+	The size, in bytes, that the object takes up on disk. See the
+	note about on-disk sizes in the `CAVEATS` section below.
+
+`deltabase`::
+	If the object is stored as a delta on-disk, this expands to the
+	40-hex sha1 of the delta base object. Otherwise, expands to the
+	null sha1 (40 zeroes). See `CAVEATS` below.
+
+`rest`::
+	If this atom is used in the output string, input lines are split
+	at the first whitespace boundary. All characters before that
+	whitespace are considered to be the object name; characters
+	after that first run of whitespace (i.e., the "rest" of the
+	line) are output in place of the `%(rest)` atom.
+
+If no format is specified, the default format is `%(objectname)
+%(objecttype) %(objectsize)`.
 
-Documentation
---------------
-Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>.
+If `--batch` is specified, the object information is followed by the
+object contents (consisting of `%(objectsize)` bytes), followed by a
+newline.
+
+For example, `--batch` without a custom format would produce:
+
+------------
+<sha1> SP <type> SP <size> LF
+<contents> LF
+------------
+
+Whereas `--batch-check='%(objectname) %(objecttype)'` would produce:
+
+------------
+<sha1> SP <type> LF
+------------
+
+If a name is specified on stdin that cannot be resolved to an object in
+the repository, then `cat-file` will ignore any custom format and print:
+
+------------
+<object> SP missing LF
+------------
+
+If --follow-symlinks is used, and a symlink in the repository points
+outside the repository, then `cat-file` will ignore any custom format
+and print:
+
+------------
+symlink SP <size> LF
+<symlink> LF
+------------
+
+The symlink will either be absolute (beginning with a /), or relative
+to the tree root.  For instance, if dir/link points to ../../foo, then
+<symlink> will be ../foo.  <size> is the size of the symlink in bytes.
+
+If --follow-symlinks is used, the following error messages will be
+displayed:
+
+------------
+<object> SP missing LF
+------------
+is printed when the initial symlink requested does not exist.
+
+------------
+dangling SP <size> LF
+<object> LF
+------------
+is printed when the initial symlink exists, but something that
+it (transitive-of) points to does not.
+
+------------
+loop SP <size> LF
+<object> LF
+------------
+is printed for symlink loops (or any symlinks that
+require more than 40 link resolutions to resolve).
+
+------------
+notdir SP <size> LF
+<object> LF
+------------
+is printed when, during symlink resolution, a file is used as a
+directory name.
+
+CAVEATS
+-------
+
+Note that the sizes of objects on disk are reported accurately, but care
+should be taken in drawing conclusions about which refs or objects are
+responsible for disk usage. The size of a packed non-delta object may be
+much larger than the size of objects which delta against it, but the
+choice of which object is the base and which is the delta is arbitrary
+and is subject to change during a repack.
+
+Note also that multiple copies of an object may be present in the object
+database; in this case, it is undefined which copy's size or delta base
+will be reported.

+=================
+
+NAME
+----
+git-check-attr - Display gitattributes information
+
+
+SYNOPSIS
+--------
+[verse]
+'git check-attr' [-a | --all | attr...] [--] pathname...
+'git check-attr' --stdin [-z] [-a | --all | attr...] < <list-of-paths>
+
+DESCRIPTION
+-----------
+For every pathname, this command will list if each attribute is 'unspecified',
+'set', or 'unset' as a gitattribute on that pathname.
+
+OPTIONS
+-------
+-a, --all::
+	List all attributes that are associated with the specified
+	paths.  If this option is used, then 'unspecified' attributes
+	will not be included in the output.
+
+--cached::
+	Consider `.gitattributes` in the index only, ignoring the working tree.
+
+--stdin::
+	Read file names from stdin instead of from the command-line.
+
+-z::
+	The output format is modified to be machine-parseable.
+	If `--stdin` is also given, input paths are separated
+	with a NUL character instead of a linefeed character.
+
+\--::
+	Interpret all preceding arguments as attributes and all following
+	arguments as path names.
+
+If none of `--stdin`, `--all`, or `--` is used, the first argument
+will be treated as an attribute and the rest of the arguments as
+pathnames.
+
+OUTPUT
+------
+
+The output is of the form:
+<path> COLON SP <attribute> COLON SP <info> LF
+
+unless `-z` is in effect, in which case NUL is used as delimiter:
+<path> NUL <attribute> NUL <info> NUL
+
+
+<path> is the path of a file being queried, <attribute> is an attribute
+being queried and <info> can be either:
+
+'unspecified';; when the attribute is not defined for the path.
+'unset';;	when the attribute is defined as false.
+'set';;		when the attribute is defined as true.
+<value>;;	when a value has been assigned to the attribute.
+
+Buffering happens as documented under the `GIT_FLUSH` option in
+linkgit:git[1].  The caller is responsible for avoiding deadlocks
+caused by overfilling an input buffer or reading from an empty output
+buffer.
+
+EXAMPLES
+--------
+

+git-check-ignore(1)
+===================
+
+NAME
+----
+git-check-ignore - Debug gitignore / exclude files
+
+
+SYNOPSIS
+--------
+[verse]
+'git check-ignore' [options] pathname...
+'git check-ignore' [options] --stdin < <list-of-paths>
+
+DESCRIPTION
+-----------
+
+For each pathname given via the command-line or from a file via
+`--stdin`, show the pattern from .gitignore (or other input files to
+the exclude mechanism) that decides if the pathname is excluded or
+included.  Later patterns within a file take precedence over earlier
+ones.
+
+By default, tracked files are not shown at all since they are not
+subject to exclude rules; but see `--no-index'.
+
+OPTIONS
+-------
+-q, --quiet::
+	Don't output anything, just set exit status.  This is only
+	valid with a single pathname.
+
+-v, --verbose::
+	Also output details about the matching pattern (if any)
+	for each given pathname.
+
+--stdin::
+	Read file names from stdin instead of from the command-line.
+
+-z::
+	The output format is modified to be machine-parseable (see
+	below).  If `--stdin` is also given, input paths are separated
+	with a NUL character instead of a linefeed character.
+
+-n, --non-matching::
+	Show given paths which don't match any pattern.	 This only
+	makes sense when `--verbose` is enabled, otherwise it would
+	not be possible to distinguish between paths which match a
+	pattern and those which don't.
+
+--no-index::
+	Don't look in the index when undertaking the checks. This can
+	be used to debug why a path became tracked by e.g. `git add .`
+	and was not ignored by the rules as expected by the user or when
+	developing patterns including negation to match a path previously
+	added with `git add -f`.
+
+OUTPUT
+------
+
+By default, any of the given pathnames which match an ignore pattern
+will be output, one per line.  If no pattern matches a given path,
+nothing will be output for that path; this means that path will not be
+ignored.
+
+If `--verbose` is specified, the output is a series of lines of the form:
+
+<source> <COLON> <linenum> <COLON> <pattern> <HT> <pathname>
+
+<pathname> is the path of a file being queried, <pattern> is the
+matching pattern, <source> is the pattern's source file, and <linenum>
+is the line number of the pattern within that source.  If the pattern
+contained a `!` prefix or `/` suffix, it will be preserved in the
+output.  <source> will be an absolute path when referring to the file
+configured by `core.excludesFile`, or relative to the repository root
+when referring to `.git/info/exclude` or a per-directory exclude file.
+
+If `-z` is specified, the pathnames in the output are delimited by the
+null character; if `--verbose` is also specified then null characters
+are also used instead of colons and hard tabs:
+
+<source> <NULL> <linenum> <NULL> <pattern> <NULL> <pathname> <NULL>
+
+If `-n` or `--non-matching` are specified, non-matching pathnames will
+also be output, in which case all fields in each output record except
+for <pathname> will be empty.  This can be useful when running
+non-interactively, so that files can be incrementally streamed to
+STDIN of a long-running check-ignore process, and for each of these
+files, STDOUT will indicate whether that file matched a pattern or
+not.  (Without this option, it would be impossible to tell whether the
+absence of output for a given file meant that it didn't match any
+pattern, or that the output hadn't been generated yet.)
+
+Buffering happens as documented under the `GIT_FLUSH` option in
+linkgit:git[1].  The caller is responsible for avoiding deadlocks
+caused by overfilling an input buffer or reading from an empty output
+buffer.
+
+EXIT STATUS
+-----------
+
+0::
+	One or more of the provided paths is ignored.
+
+1::
+	None of the provided paths are ignored.

+  dot `.` or end with the sequence `.lock`.
+
+. They must contain at least one `/`. This enforces the presence of a

+
+. at-open-brace `@{` is used as a notation to access a reflog entry.
+
+With the `--branch` option, it expands the ``previous branch syntax''
+`@{-n}`.  For example, `@{-1}` is a way to refer the last branch you
+were on.  This option should be used by porcelains to accept this
+syntax anywhere a branch name is expected, so they can act as if you
+typed the branch name.
+
+OPTIONS
+-------
+--[no-]allow-onelevel::
+	Controls whether one-level refnames are accepted (i.e.,
+	refnames that do not contain multiple `/`-separated
+	components).  The default is `--no-allow-onelevel`.
+
+--refspec-pattern::
+	Interpret <refname> as a reference name pattern for a refspec
+	(as used with remote repositories).  If this option is
+	enabled, <refname> is allowed to contain a single `*`
+	in the refspec (e.g., `foo/bar*/baz` or `foo/bar*baz/`
+	but not `foo/bar*/baz*`).
+
+--normalize::
+	Normalize 'refname' by removing any leading slash (`/`)
+	characters and collapsing runs of adjacent slashes between
+	name components into a single slash.  Iff the normalized
+	refname is valid then print it to standard output and exit
+	with a status of 0.  (`--print` is a deprecated way to spell
+	`--normalize`.)
+
+
+EXAMPLES
+--------
+
+* Print the name of the previous branch:
++
+------------
+$ git check-ref-format --branch @{-1}
+------------
 
+* Determine the reference name to use for a new branch:

-'git-checkout' [<tree-ish>] <paths>...
+'git checkout' [-q] [-f] [-m] [<branch>]

+'git checkout' [-f|--ours|--theirs|-m|--conflict=<style>] [<tree-ish>] [--] <paths>...
+'git checkout' [-p|--patch] [<tree-ish>] [--] [<paths>...]
 
 DESCRIPTION
 -----------
+Updates files in the working tree to match the version in the index
+or the specified tree.  If no paths are given, 'git checkout' will
+also update `HEAD` to set the specified branch as the current
+branch.
 
-When <paths> are not given, this command switches branches by
-updating the index and working tree to reflect the specified
-branch, <branch>, and updating HEAD to be <branch> or, if
-specified, <new_branch>.  Using -b will cause <new_branch> to
-be created.
+'git checkout' <branch>::
+	To prepare for working on <branch>, switch to it by updating
+	the index and the files in the working tree, and by pointing
+	HEAD at the branch. Local modifications to the files in the
+	working tree are kept, so that they can be committed to the
+	<branch>.
++
+If <branch> is not found but there does exist a tracking branch in
+exactly one remote (call it <remote>) with a matching name, treat as
+equivalent to
++
+------------
+$ git checkout -b <branch> --track <remote>/<branch>
+------------
++
+You could omit <branch>, in which case the command degenerates to
+"check out the current branch", which is a glorified no-op with a
+rather expensive side-effects to show only the tracking information,
+if exists, for the current branch.
+
+'git checkout' -b|-B <new_branch> [<start point>]::
 
-When <paths> are given, this command does *not* switch
-branches.  It updates the named paths in the working tree from
-the index file (i.e. it runs `git-checkout-index -f -u`), or a
-named commit.  In
-this case, `-f` and `-b` options are meaningless and giving
-either of them results in an error.  <tree-ish> argument can be
-used to specify a specific tree-ish (i.e. commit, tag or tree)
-to update the index for the given paths before updating the
-working tree.
+	Specifying `-b` causes a new branch to be created as if
+	linkgit:git-branch[1] were called and then checked out.  In
+	this case you can use the `--track` or `--no-track` options,
+	which will be passed to 'git branch'.  As a convenience,
+	`--track` without `-b` implies branch creation; see the
+	description of `--track` below.
++
+If `-B` is given, <new_branch> is created if it doesn't exist; otherwise, it
+is reset. This is the transactional equivalent of
++
+------------
+$ git branch -f <branch> [<start point>]
+$ git checkout <branch>
+------------
++
+that is to say, the branch is not reset/created unless "git checkout" is
+successful.
 
+'git checkout' --detach [<branch>]::
+'git checkout' [--detach] <commit>::
+
+	Prepare to work on top of <commit>, by detaching HEAD at it
+	(see "DETACHED HEAD" section), and updating the index and the
+	files in the working tree.  Local modifications to the files
+	in the working tree are kept, so that the resulting working
+	tree will be the state recorded in the commit plus the local
+	modifications.
++
+When the <commit> argument is a branch name, the `--detach` option can
+be used to detach HEAD at the tip of the branch (`git checkout
+<branch>` would check out that branch without detaching HEAD).
++
+Omitting <branch> detaches HEAD at the tip of the current branch.
+
+'git checkout' [-p|--patch] [<tree-ish>] [--] <pathspec>...::
+
+	When <paths> or `--patch` are given, 'git checkout' does *not*
+	switch branches.  It updates the named paths in the working tree
+	from the index file or from a named <tree-ish> (most often a
+	commit).  In this case, the `-b` and `--track` options are
+	meaningless and giving either of them results in an error.  The
+	<tree-ish> argument can be used to specify a specific tree-ish
+	(i.e.  commit, tag or tree) to update the index for the given
+	paths before updating the working tree.
++
+'git checkout' with <paths> or `--patch` is used to restore modified or
+deleted paths to their original contents from the index or replace paths
+with the contents from a named <tree-ish> (most often a commit-ish).
++
+The index may contain unmerged entries because of a previous failed merge.
+By default, if you try to check out such an entry from the index, the
+checkout operation will fail and nothing will be checked out.
+Using `-f` will ignore these unmerged entries.  The contents from a
+specific side of the merge can be checked out of the index by
+using `--ours` or `--theirs`.  With `-m`, changes made to the working tree
+file can be discarded to re-create the original conflicted merge result.

+--ours::
+--theirs::
+	When checking out paths from the index, check out stage #2
+	('ours') or #3 ('theirs') for unmerged paths.
++
+Note that during `git rebase` and `git pull --rebase`, 'ours' and
+'theirs' may appear swapped; `--ours` gives the version from the
+branch the changes are rebased onto, while `--theirs` gives the
+version from the branch that holds your work that is being rebased.
++
+This is because `rebase` is used in a workflow that treats the
+history at the remote as the shared canonical one, and treats the
+work done on the branch you are rebasing as the third-party work to
+be integrated, and you are temporarily assuming the role of the
+keeper of the canonical history during the rebase.  As the keeper of
+the canonical history, you need to view the history from the remote
+as `ours` (i.e. "our shared canonical history"), while what you did
+on your side branch as `theirs` (i.e. "one contributor's work on top
+of it").

+The index and the working tree are adjusted as if you had previously run
+"git checkout <start_point>".  This allows you to start a new history

++
+This can be useful when you want to publish the tree from a commit
+without exposing its full history. You might want to do this to publish

+whose full history contains proprietary or otherwise encumbered bits of
+code.
++
+If you want to start a disconnected history that records a set of paths

+parent is commit 'c', and then updates branch 'master' to refer to new
+commit 'd'. HEAD still refers to branch 'master' and so indirectly now refers

-Earlier versions of git did not allow this and asked you to
-create a temporary branch using `-b` option, but starting from
-version 1.5.0, the above command 'detaches' your HEAD from the
-current branch and directly point at the commit named by the tag
-(`v2.6.18` in the above example).
+It is sometimes useful to be able to checkout a commit that is not at
+the tip of any named branch, or even to create a new commit that is not
+referenced by a named branch. Let's look at what happens when we
+checkout commit 'b' (here we show two ways this may be done):
 
-You can use usual git commands while in this state.  You can use
-`git-reset --hard $othercommit` to further move around, for
-example.  You can make changes and create a new commit on top of
-a detached HEAD.  You can even create a merge by using `git
-merge $othercommit`.
+------------
+$ git checkout v2.0  # or
+$ git checkout master^^
 
-The state you are in while your HEAD is detached is not recorded
-by any branch (which is natural --- you are not on any branch).
-What this means is that you can discard your temporary commits
-and merges by switching back to an existing branch (e.g. `git
-checkout master`), and a later `git prune` or `git gc` would
-garbage-collect them.  If you did this by mistake, you can ask
-the reflog for HEAD where you were, e.g.
+   HEAD (refers to commit 'b')
+    |
+    v
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+Notice that regardless of which checkout command we use, HEAD now refers
+directly to commit 'b'. This is known as being in detached HEAD state.
+It means simply that HEAD refers to a specific commit, as opposed to
+referring to a named branch. Let's see what happens when we create a commit:
 
 ------------
-$ git log -g -2 HEAD
+$ edit; git add; git commit
+
+     HEAD (refers to commit 'e')
+      |
+      v
+      e
+     /
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+There is now a new commit 'e', but it is referenced only by HEAD. We can
+of course add yet another commit in this state:
+
+------------
+$ edit; git add; git commit
+
+	 HEAD (refers to commit 'f')
+	  |
+	  v
+      e---f
+     /
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+In fact, we can perform all the normal Git operations. But, let's look
+at what happens when we then checkout master:
+
+------------
+$ git checkout master
+
+	       HEAD (refers to branch 'master')
+      e---f     |
+     /          v
+a---b---c---d  branch 'master' (refers to commit 'd')
+    ^
+    |
+  tag 'v2.0' (refers to commit 'b')
+------------
+
+It is important to realize that at this point nothing refers to commit
+'f'. Eventually commit 'f' (and by extension commit 'e') will be deleted
+by the routine Git garbage collection process, unless we create a reference
+before that happens. If we have not yet moved away from commit 'f',
+any of these will create a reference to it:
+
+------------
+$ git checkout -b foo   <1>
+$ git branch foo        <2>
+$ git tag foo           <3>
 ------------
 
+<1> creates a new branch 'foo', which refers to commit 'f', and then
+updates HEAD to refer to branch 'foo'. In other words, we'll no longer
+be in detached HEAD state after this command.
+
+<2> similarly creates a new branch 'foo', which refers to commit 'f',
+but leaves HEAD detached.
+
+<3> creates a new tag 'foo', which refers to commit 'f',
+leaving HEAD detached.
+
+If we have moved away from commit 'f', then we must first recover its object
+name (typically by using git reflog), and then we can create a reference to
+it. For example, to see the last two commits to which HEAD referred, we
+can use either of these commands:
+
+------------
+$ git reflog -2 HEAD # or
+$ git log -g -2 HEAD
+------------

 DESCRIPTION
 -----------
-Given one existing commit, apply the change the patch introduces, and record a
-new commit that records it.  This requires your working tree to be clean (no
-modifications from the HEAD commit).
+
+Given one or more existing commits, apply the change each one
+introduces, recording a new commit for each.  This requires your
+working tree to be clean (no modifications from the HEAD commit).
+
+When it is not obvious how to apply a change, the following
+happens:
+
+1. The current branch and `HEAD` pointer stay at the last commit
+   successfully made.
+2. The `CHERRY_PICK_HEAD` ref is set to point at the commit that
+   introduced the change that is difficult to apply.
+3. Paths in which the change applied cleanly are updated both
+   in the index file and in your working tree.
+4. For conflicting paths, the index file records up to three
+   versions, as described in the "TRUE MERGE" section of
+   linkgit:git-merge[1].  The working tree files will include
+   a description of the conflict bracketed by the usual
+   conflict markers `<<<<<<<` and `>>>>>>>`.
+5. No other modifications are made.
+
+See linkgit:git-merge[1] for some hints on resolving such
+conflicts.
 
 OPTIONS
 -------

+	Commits to cherry-pick.
 	For a more complete list of ways to spell commits, see
-	"SPECIFYING REVISIONS" section in gitlink:git-rev-parse[1].
+	linkgit:gitrevisions[7].
+	Sets of commits can be passed but no traversal is done by
+	default, as if the '--no-walk' option was specified, see
+	linkgit:git-rev-list[1]. Note that specifying a range will
+	feed all <commit>... arguments to a single revision walk
+	(see a later example that uses 'maint master..next').
 
--e|--edit::
-	With this option, `git-cherry-pick` will let you edit the commit
-	message prior committing.
+-e::
+--edit::
+	With this option, 'git cherry-pick' will let you edit the commit
+	message prior to committing.
 
 -x::
-	Cause the command to append which commit was
-	cherry-picked after the original commit message when
-	making a commit.  Do not use this option if you are
-	cherry-picking from your private branch because the
-	information is useless to the recipient.  If on the
+	When recording the commit, append a line that says
+	"(cherry picked from commit ...)" to the original commit
+	message in order to indicate which commit this change was
+	cherry-picked from.  This is done only for cherry
+	picks without conflicts.  Do not use this option if
+	you are cherry-picking from your private branch because
+	the information is useless to the recipient.  If on the
 	other hand you are cherry-picking between two publicly
 	visible branches (e.g. backporting a fix to a
 	maintenance branch for an older release from a
 	development branch), adding this information can be
 	useful.
 
--r|--replay::
+-r::
 	It used to be that the command defaulted to do `-x`
 	described above, and `-r` was to disable it.  Now the
 	default is not to do `-x` so this option is a no-op.
 
--n|--no-commit::
-	Usually the command automatically creates a commit with
-	a commit log message stating which commit was
-	cherry-picked.  This flag applies the change necessary
-	to cherry-pick the named commit to your working tree,
-	but does not make the commit.  In addition, when this
-	option is used, your working tree does not have to match
-	the HEAD commit.  The cherry-pick is done against the
-	beginning state of your working tree.
+-m parent-number::
+--mainline parent-number::
+	Usually you cannot cherry-pick a merge because you do not know which
+	side of the merge should be considered the mainline.  This
+	option specifies the parent number (starting from 1) of
+	the mainline and allows cherry-pick to replay the change
+	relative to the specified parent.
+
+-n::
+--no-commit::
+	Usually the command automatically creates a sequence of commits.
+	This flag applies the changes necessary to cherry-pick
+	each named commit to your working tree and the index,
+	without making any commit.  In addition, when this
+	option is used, your index does not have to match the
+	HEAD commit.  The cherry-pick is done against the

 This is useful when cherry-picking more than one commits'

+-s::
+--signoff::
+	Add Signed-off-by line at the end of the commit message.
+
+-S[<keyid>]::
+--gpg-sign[=<keyid>]::
+	GPG-sign commits. The `keyid` argument is optional and
+	defaults to the committer identity; if specified, it must be

+
+--ff::
+	If the current HEAD is the same as the parent of the
+	cherry-pick'ed commit, then a fast forward to this commit will
+	be performed.
+
+--allow-empty::
+	By default, cherry-picking an empty commit will fail,
+	indicating that an explicit invocation of `git commit
+	--allow-empty` is required. This option overrides that
+	behavior, allowing empty commits to be preserved automatically
+	in a cherry-pick. Note that when "--ff" is in effect, empty
+	commits that meet the "fast-forward" requirement will be kept
+	even without this option.  Note also, that use of this option only
+	keeps commits that were initially empty (i.e. the commit recorded the
+	same tree as its parent).  Commits which are made empty due to a
+	previous commit are dropped.  To force the inclusion of those commits
+	use `--keep-redundant-commits`.
+
+--allow-empty-message::
+	By default, cherry-picking a commit with an empty message will fail.
+	This option overrides that behaviour, allowing commits with empty
+	messages to be cherry picked.
+
+--keep-redundant-commits::
+	If a commit being cherry picked duplicates a commit already in the
+	current history, it will become empty.  By default these
+	redundant commits cause `cherry-pick` to stop so the user can
+	examine the commit. This option overrides that behavior and
+	creates an empty commit object.  Implies `--allow-empty`.
+
+--strategy=<strategy>::
+	Use the given merge strategy.  Should only be used once.
+	See the MERGE STRATEGIES section in linkgit:git-merge[1]
+	for details.

+-X<option>::
+--strategy-option=<option>::
+	Pass the merge strategy-specific option through to the

 SYNOPSIS
 --------
-'git-cherry' [-v] <upstream> [<head>] [<limit>]
+[verse]
+'git cherry' [-v] [<upstream> [<head> [<limit>]]]
 
 DESCRIPTION
 -----------
-The changeset (or "diff") of each commit between the fork-point and <head>
-is compared against each commit between the fork-point and <upstream>.
+Determine whether there are commits in `<head>..<upstream>` that are
+equivalent to those in the range `<limit>..<head>`.
 
-Every commit that doesn't exist in the <upstream> branch
-has its id (sha1) reported, prefixed by a symbol.  The ones that have
-equivalent change already
-in the <upstream> branch are prefixed with a minus (-) sign, and those
-that only exist in the <head> branch are prefixed with a plus (+) symbol:
-
-               __*__*__*__*__> <upstream>
-              /
-    fork-point
-              \__+__+__-__+__+__-__+__> <head>
-
-
-If a <limit> has been given then the commits along the <head> branch up
-to and including <limit> are not reported:
-
-               __*__*__*__*__> <upstream>
-              /
-    fork-point
-              \__*__*__<limit>__-__+__> <head>
-
-
-Because git-cherry compares the changeset rather than the commit id
-(sha1), you can use git-cherry to find out if a commit you made locally
-has been applied <upstream> under a different commit id.  For example,
-this will happen if you're feeding patches <upstream> via email rather
-than pushing or pulling commits directly.
+The equivalence test is based on the diff, after removing whitespace
+and line numbers.  git-cherry therefore detects when commits have been
+"copied" by means of linkgit:git-cherry-pick[1], linkgit:git-am[1] or
+linkgit:git-rebase[1].
 
+Outputs the SHA1 of every commit in `<limit>..<head>`, prefixed with
+`-` for commits that have an equivalent in <upstream>, and `+` for
+commits that do not.
 
 OPTIONS
 -------
 -v::
-	Verbose.
+	Show the commit subjects next to the SHA1s.
 
 <upstream>::
-	Upstream branch to compare against.
+	Upstream branch to search for equivalent commits.
+	Defaults to the upstream branch of HEAD.
 
 <head>::
 	Working branch; defaults to HEAD.

+
+Patch workflows
+~~~~~~~~~~~~~~~
+
+git-cherry is frequently used in patch-based workflows (see
+linkgit:gitworkflows[7]) to determine if a series of patches has been
+applied by the upstream maintainer.  In such a workflow you might
+create and send a topic branch like this:
+
+------------
+$ git checkout -b topic origin/master
+# work and create some commits
+$ git format-patch origin/master
+$ git send-email ... 00*
+------------
+
+Later, you can see whether your changes have been applied by saying
+(still on `topic`):
+
+------------
+$ git fetch  # update your notion of origin/master
+$ git cherry -v
+------------
+
+Concrete example
+~~~~~~~~~~~~~~~~
+
+In a situation where topic consisted of three commits, and the
+maintainer applied two of them, the situation might look like:
+
+------------
+$ git log --graph --oneline --decorate --boundary origin/master...topic
+* 7654321 (origin/master) upstream tip commit
+[... snip some other commits ...]
+* cccc111 cherry-pick of C
+* aaaa111 cherry-pick of A
+[... snip a lot more that has happened ...]
+| * cccc000 (topic) commit C
+| * bbbb000 commit B
+| * aaaa000 commit A
+|/
+o 1234567 branch point
+------------
+
+In such cases, git-cherry shows a concise summary of what has yet to
+be applied:
+
+------------
+$ git cherry origin/master topic
+- cccc000... commit C
++ bbbb000... commit B
+- aaaa000... commit A
+------------
+
+Here, we see that the commits A and C (marked with `-`) can be
+dropped from your `topic` branch when you rebase it on top of
+`origin/master`, while the commit B (marked with `+`) still needs to
+be kept so that it will be sent to be applied to `origin/master`.
+
+
+Using a limit
+~~~~~~~~~~~~~
+
+The optional <limit> is useful in cases where your topic is based on
+other work that is not in upstream.  Expanding on the previous
+example, this might look like:
+
+------------
+$ git log --graph --oneline --decorate --boundary origin/master...topic
+* 7654321 (origin/master) upstream tip commit
+[... snip some other commits ...]
+* cccc111 cherry-pick of C
+* aaaa111 cherry-pick of A
+[... snip a lot more that has happened ...]
+| * cccc000 (topic) commit C
+| * bbbb000 commit B
+| * aaaa000 commit A
+| * 0000fff (base) unpublished stuff F
+[... snip ...]
+| * 0000aaa unpublished stuff A
+|/
+o 1234567 merge-base between upstream and topic
+------------
+
+By specifying `base` as the limit, you can avoid listing commits
+between `base` and `topic`:
+
+------------
+$ git cherry origin/master topic base
+- cccc000... commit C
++ bbbb000... commit B
+- aaaa000... commit A
+------------

+----------------

+with a single '>', you can pick only one of the choices given
+and type return, like this:

+You also could say `c` or `clean` above as long as the choice is unique.
+
+The main command loop has 6 subcommands.

 DESCRIPTION

 remote-tracking branches for each branch in the cloned repository

-branch equal to the cloned repository's currently active branch.

+initial branch that is forked from the cloned repository's

 all the remote-tracking branches, and a `git pull` without
 arguments will in addition merge the remote master branch into the
-current master branch, if any.

 This default configuration is achieved by creating references to

 by initializing `remote.origin.url` and `remote.origin.fetch`
 configuration variables.

+The content to be added can be specified in several ways:
+
+1. by using 'git add' to incrementally "add" changes to the
+   index before using the 'commit' command (Note: even modified
    files must be "added");
 
-2. by using gitlink:git-rm[1] to identify content removal for the next
-   commit, again before using the 'commit' command;
+2. by using 'git rm' to remove files from the working tree
+   and the index, again before using the 'commit' command;
+
+3. by listing files as arguments to the 'commit' command, in which
+   case the commit will ignore changes staged in the index, and instead

+
+-c <commit>::
+--reedit-message=<commit>::
+	Like '-C', but with '-c' the editor is invoked, so that
+	the user can further edit the commit message.
+
+--fixup=<commit>::
+	Construct a commit message for use with `rebase --autosquash`.
+	The commit message will be the subject line from the specified
+	commit with a prefix of "fixup! ".  See linkgit:git-rebase[1]
+	for details.
+
+--squash=<commit>::
+	Construct a commit message for use with `rebase --autosquash`.
+	The commit message subject line is taken from the specified
+	commit with a prefix of "squash! ".  Can be used with additional
+	commit message options (`-m`/`-c`/`-C`/`-F`). See
+	linkgit:git-rebase[1] for details.
+
+--reset-author::
+	When used with -C/-c/--amend options, or when committing after a
+	a conflicting cherry-pick, declare that the authorship of the
+	resulting commit now belongs to the committer. This also renews
+	the author timestamp.
+
+--short::
+	When doing a dry-run, give the output in the short-format. See
+	linkgit:git-status[1] for details. Implies `--dry-run`.
+
+--branch::
+	Show the branch and tracking info even in short-format.
+
+--porcelain::
+	When doing a dry-run, give the output in a porcelain-ready
+	format. See linkgit:git-status[1] for details. Implies
+	`--dry-run`.
+
+--long::
+	When doing a dry-run, give the output in a the long-format.
+	Implies `--dry-run`.
+
+-z::
+--null::
+	When showing `short` or `porcelain` status output, terminate
+	entries in the status output with NUL, instead of LF. If no
+	format is given, implies the `--porcelain` output format.
 
 -F <file>::
+--file=<file>::
 	Take the commit message from the given file.  Use '-' to
 	read the message from the standard input.
 
---author <author>::
-	Override the author name used in the commit.  Use
-	`A U Thor <author@example.com>` format.
+--author=<author>::
+	Override the commit author. Specify an explicit author using the
+	standard `A U Thor <author@example.com>` format. Otherwise <author>
+	is assumed to be a pattern and is used to search for an existing
+	commit by that author (i.e. rev-list --all -i --author=<author>);
+	the commit author is then copied from the first such commit found.
+
+--date=<date>::
+	Override the author date used in the commit.
 
 -m <msg>::
+--message=<msg>::
 	Use the given <msg> as the commit message.
-
--s|--signoff::
-	Add Signed-off-by line at the end of the commit message.
-
+	If multiple `-m` options are given, their values are
+	concatenated as separate paragraphs.
+
+-t <file>::
+--template=<file>::
+	When editing the commit message, start the editor with the
+	contents in the given file.  The `commit.template` configuration
+	variable is often used to give this option implicitly to the
+	command.  This mechanism can be used by projects that want to
+	guide participants with some hints on what to write in the message
+	in what order.  If the user exits the editor without editing the
+	message, the commit is aborted.  This has no effect when a message
+	is given by other means, e.g. with the `-m` or `-F` options.
+
+-s::
+--signoff::
+	Add Signed-off-by line by the committer at the end of the commit
+	log message.
+
+-n::
 --no-verify::
-	This option bypasses the pre-commit hook.
-	See also link:hooks.html[hooks].
+	This option bypasses the pre-commit and commit-msg hooks.
+	See also linkgit:githooks[5].
+
+--allow-empty::
+	Usually recording a commit that has the exact same tree as its
+	sole parent commit is a mistake, and the command prevents you
+	from making such a commit.  This option bypasses the safety, and
+	is primarily for use by foreign SCM interface scripts.
+
+--allow-empty-message::
+       Like --allow-empty this command is primarily for use by foreign
+       SCM interface scripts. It allows you to create a commit with an
+       empty commit message without using plumbing commands like
+       linkgit:git-commit-tree[1].
+
+--cleanup=<mode>::
+	This option determines how the supplied commit message should be
+	cleaned up before committing.  The '<mode>' can be `strip`,
+	`whitespace`, `verbatim`, `scissors` or `default`.
++
+--
+strip::
+	Strip leading and trailing empty lines, trailing whitespace,
+	commentary and collapse consecutive empty lines.
+whitespace::
+	Same as `strip` except #commentary is not removed.
+verbatim::
+	Do not change the message at all.
+scissors::
+	Same as `whitespace`, except that everything from (and
+	including) the line
+	"`# ------------------------ >8 ------------------------`"
+	is truncated if the message is to be edited. "`#`" can be
+	customized with core.commentChar.
+default::
+	Same as `strip` if the message is to be edited.
+	Otherwise `whitespace`.
+--
++
+The default can be changed by the 'commit.cleanup' configuration
+variable (see linkgit:git-config[1]).
 
--e|--edit::

+--edit::
 	The message taken from file with `-F`, command line with

-	Used to amend the tip of the current branch. Prepare the tree

-	current tip -- if it was a merge, it will have the parents of
-	the current tip as parents -- so the current top commit is

+--amend::
+	Replace the tip of the current branch by creating a new
+	commit. The recorded tree is prepared as usual (including
+	the effect of the `-i` and `-o` options and explicit
+	pathspec), and the message from the original commit is used
+	as the starting point, instead of an empty message, when no

+
+$XDG_CONFIG_HOME/git/config::
+	Second user-specific configuration file. If $XDG_CONFIG_HOME is not set
+	or empty, `$HOME/.config/git/config` will be used. Any single-valued
+	variable set in this file will be overwritten by whatever is in
+	`~/.gitconfig`.  It is a good idea not to create this file if
+	you sometimes use older versions of Git, as support for this
+	file was added fairly recently.
+
+~/.gitconfig::
+	User-specific configuration file. Also called "global"
+	configuration file.
+
+$GIT_DIR/config::
+	Repository specific configuration file.
+
+If no further options are given, all reading options will read all of these
+files that are available. If the global or the system-wide configuration
+file are not available they will be ignored. If the repository configuration
+file is not available or readable, 'git config' will exit with a non-zero
+error code. However, in neither case will an error message be issued.
+
+The files are read in the order given above, with last value found taking
+precedence over values read earlier.  When multiple values are taken then all
+values of a key from all files will be used.
+
+All writing options will per default write to the repository specific
+configuration file. Note that this also affects options like '--replace-all'
+and '--unset'. *'git config' will only ever change one file at a time*.
+
+You can override these rules either by command-line options or by environment
+variables. The '--global' and the '--system' options will limit the file used
+to the global or system-wide file respectively. The GIT_CONFIG environment
+variable has a similar effect, but you can specify any filename you want.

+NAME
+----
+git-credential-cache - Helper to temporarily store passwords in memory
+
+SYNOPSIS
+--------
+-----------------------------
+git config credential.helper 'cache [options]'
+-----------------------------
+
+DESCRIPTION
+-----------
+
+This command caches credentials in memory for use by future Git
+programs. The stored credentials never touch the disk, and are forgotten
+after a configurable timeout.  The cache is accessible over a Unix
+domain socket, restricted to the current user by filesystem permissions.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of Git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--timeout <seconds>::
+
+	Number of seconds to cache credentials (default: 900).
+
+--socket <path>::
+
+	Use `<path>` to contact a running cache daemon (or start a new
+	cache daemon if one is not started). Defaults to
+	`~/.git-credential-cache/socket`. If your home directory is on a
+	network-mounted filesystem, you may need to change this to a
+	local filesystem.
+
+CONTROLLING THE DAEMON
+----------------------
+
+If you would like the daemon to exit early, forgetting all cached
+credentials before their timeout, you can issue an `exit` action:
+
+--------------------------------------
+git credential-cache exit
+--------------------------------------
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------
+$ git config credential.helper cache
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[work for 5 more minutes]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------
+
+You can provide options via the credential.helper configuration
+variable (this example drops the cache time to 5 minutes):
+
+-------------------------------------------------------
+$ git config credential.helper 'cache --timeout=300'

+git-credential-store - Helper to store credentials on disk
+
+SYNOPSIS
+--------
+-------------------
+git config credential.helper 'store [options]'
+-------------------
+
+DESCRIPTION
+-----------
+
+NOTE: Using this helper will store your passwords unencrypted on disk,
+protected only by filesystem permissions. If this is not an acceptable
+security tradeoff, try linkgit:git-credential-cache[1], or find a helper
+that integrates with secure storage provided by your operating system.
+
+This command stores credentials indefinitely on disk for use by future
+Git programs.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--file=<path>::
+
+	Use `<path>` to lookup and store credentials. The file will have its
+	filesystem permissions set to prevent other users on the system
+	from reading it, but will not be encrypted or otherwise
+	protected. If not specified, credentials will be searched for from
+	`~/.git-credentials` and `$XDG_CONFIG_HOME/git/credentials`, and
+	credentials will be written to `~/.git-credentials` if it exists, or
+	`$XDG_CONFIG_HOME/git/credentials` if it exists and the former does
+	not. See also <<FILES>>.
+
+[[FILES]]
+FILES
+-----
+
+If not set explicitly with '--file', there are two files where
+git-credential-store will search for credentials in order of precedence:
+
+~/.git-credentials::
+	User-specific credentials file.
+
+$XDG_CONFIG_HOME/git/credentials::
+	Second user-specific credentials file. If '$XDG_CONFIG_HOME' is not set
+	or empty, `$HOME/.config/git/credentials` will be used. Any credentials
+	stored in this file will not be used if `~/.git-credentials` has a
+	matching credential as well. It is a good idea not to create this file
+	if you sometimes use older versions of Git that do not support it.
+
+For credential lookups, the files are read in the order given above, with the
+first matching credential found taking precedence over credentials found in
+files further down the list.
+
+Credential storage will by default write to the first existing file in the
+list. If none of these files exist, `~/.git-credentials` will be created and
+written to.
+
+When erasing credentials, matching credentials will be erased from all files.
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------------
+$ git config credential.helper store
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[several days later]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------------
+
+STORAGE FORMAT
+--------------
+
+The `.git-credentials` file is stored in plaintext. Each credential is
+stored on its own line as a URL like:
+
+------------------------------
+https://user:pass@example.com
+------------------------------
+
+When Git needs authentication for a particular URL context,
+credential-store will consider that context a pattern to match against
+each entry in the credentials file.  If the protocol, hostname, and
+username (if we already have one) match, then the password is returned
+to Git. See the discussion of configuration in linkgit:gitcredentials[7]
+for more information.

+git-credential(1)
+=================
+
+NAME
+----
+git-credential - Retrieve and store user credentials
+
+SYNOPSIS
+--------
+------------------
+git credential <fill|approve|reject>
+------------------
+
+DESCRIPTION
+-----------
+
+Git has an internal interface for storing and retrieving credentials
+from system-specific helpers, as well as prompting the user for
+usernames and passwords. The git-credential command exposes this
+interface to scripts which may want to retrieve, store, or prompt for
+credentials in the same manner as Git. The design of this scriptable
+interface models the internal C API; see
+link:technical/api-credentials.html[the Git credential API] for more
+background on the concepts.
+
+git-credential takes an "action" option on the command-line (one of
+`fill`, `approve`, or `reject`) and reads a credential description
+on stdin (see <<IOFMT,INPUT/OUTPUT FORMAT>>).
+
+If the action is `fill`, git-credential will attempt to add "username"
+and "password" attributes to the description by reading config files,
+by contacting any configured credential helpers, or by prompting the
+user. The username and password attributes of the credential
+description are then printed to stdout together with the attributes
+already provided.
+
+If the action is `approve`, git-credential will send the description
+to any configured credential helpers, which may store the credential
+for later use.
+
+If the action is `reject`, git-credential will send the description to
+any configured credential helpers, which may erase any stored
+credential matching the description.
+
+If the action is `approve` or `reject`, no output should be emitted.
+
+TYPICAL USE OF GIT CREDENTIAL
+-----------------------------
+
+An application using git-credential will typically use `git
+credential` following these steps:
+
+  1. Generate a credential description based on the context.
++
+For example, if we want a password for
+`https://example.com/foo.git`, we might generate the following
+credential description (don't forget the blank line at the end; it
+tells `git credential` that the application finished feeding all the
+information it has):
+
+	 protocol=https
+	 host=example.com
+	 path=foo.git
+
+  2. Ask git-credential to give us a username and password for this
+     description. This is done by running `git credential fill`,
+     feeding the description from step (1) to its standard input. The complete
+     credential description (including the credential per se, i.e. the
+     login and password) will be produced on standard output, like:
+
+	protocol=https
+	host=example.com
+	username=bob
+	password=secr3t
++
+In most cases, this means the attributes given in the input will be
+repeated in the output, but Git may also modify the credential
+description, for example by removing the `path` attribute when the
+protocol is HTTP(s) and `credential.useHttpPath` is false.
++
+If the `git credential` knew about the password, this step may
+not have involved the user actually typing this password (the
+user may have typed a password to unlock the keychain instead,
+or no user interaction was done if the keychain was already
+unlocked) before it returned `password=secr3t`.
+
+  3. Use the credential (e.g., access the URL with the username and
+     password from step (2)), and see if it's accepted.
+
+  4. Report on the success or failure of the password. If the
+     credential allowed the operation to complete successfully, then
+     it can be marked with an "approve" action to tell `git
+     credential` to reuse it in its next invocation. If the credential
+     was rejected during the operation, use the "reject" action so
+     that `git credential` will ask for a new password in its next
+     invocation. In either case, `git credential` should be fed with
+     the credential description obtained from step (2) (which also
+     contain the ones provided in step (1)).
+
+[[IOFMT]]
+INPUT/OUTPUT FORMAT
+-------------------
+
+`git credential` reads and/or writes (depending on the action used)
+credential information in its standard input/output. This information
+can correspond either to keys for which `git credential` will obtain
+the login/password information (e.g. host, protocol, path), or to the
+actual credential data to be obtained (login/password).
+
+The credential is split into a set of named attributes, with one
+attribute per line. Each attribute is
+specified by a key-value pair, separated by an `=` (equals) sign,
+followed by a newline. The key may contain any bytes except `=`,
+newline, or NUL. The value may contain any bytes except newline or NUL.
+In both cases, all bytes are treated as-is (i.e., there is no quoting,
+and one cannot transmit a value with newline or NUL in it). The list of
+attributes is terminated by a blank line or end-of-file.
+Git understands the following attributes:
+
+`protocol`::
+
+	The protocol over which the credential will be used (e.g.,
+	`https`).
+
+`host`::
+
+	The remote hostname for a network credential.
+
+`path`::
+
+	The path with which the credential will be used. E.g., for
+	accessing a remote https repository, this will be the
+	repository's path on the server.
+
+`username`::
+
+	The credential's username, if we already have one (e.g., from a
+	URL, from the user, or from a previously run helper).
+
+`password`::
+
+	The credential's password, if we are asking it to be stored.
+
+`url`::
+
+	When this special attribute is read by `git credential`, the
+	value is parsed as a URL and treated as if its constituent parts
+	were read (e.g., `url=https://example.com` would behave as if
+	`protocol=https` and `host=example.com` had been provided). This
+	can help callers avoid parsing URLs themselves.  Note that any
+	components which are missing from the URL (e.g., there is no
+	username in the example above) will be set to empty; if you want
+	to provide a URL and override some attributes, provide the URL
+	attribute first, followed by any overrides.

 DESCRIPTION

+*WARNING:* `git cvsimport` uses cvsps version 2, which is considered
+deprecated; it does not work with cvsps version 3 and later.  If you are
+performing a one-shot import of a CVS repository consider using

+https://github.com/BartMassey/parsecvs[parsecvs].
+
+Imports a CVS repository into Git. It will either create a new
 repository, or incrementally import into an existing one.
 
 Splitting the CVS log into patch sets is done by 'cvsps'.
 At least version 2.1 is required.
 
+*WARNING:* for certain situations the import leads to incorrect results.
+Please see the section <<issues,ISSUES>> for further reference.
+
 You should *never* do any work of your own on the branches that are
-created by git-cvsimport. The initial import will create and populate a
+created by 'git cvsimport'.  By default initial import will create and populate a
 "master" branch from the CVS repository's main branch which you're free
 to work with; after that, you need to 'git merge' incremental imports, or
-any CVS branches, yourself.
+any CVS branches, yourself.  It is advisable to specify a named remote via
+-r to separate and protect the incoming branches.
+
+If you intend to set up a shared public repository that all developers can
+read/write, or if you want to use linkgit:git-cvsserver[1], then you
+probably want to make a bare clone of the imported repository,
+and use the clone as the shared repository.
+See linkgit:gitcvs-migration[7].

+ISSUES
 ------
-Written by Matthias Urlichs <smurf@smurf.noris.de>, with help from
-various participants of the git-list <git@vger.kernel.org>.
+Problems related to timestamps:
+
+ * If timestamps of commits in the CVS repository are not stable enough
+   to be used for ordering commits changes may show up in the wrong
+   order.
+ * If any files were ever "cvs import"ed more than once (e.g., import of
+   more than one vendor release) the HEAD contains the wrong content.
+ * If the timestamp order of different files cross the revision order
+   within the commit matching time window the order of commits may be
+   wrong.
+
+Problems related to branches:
+
+ * Branches on which no commits have been made are not imported.
+ * All files from the branching point are added to a branch even if
+   never added in CVS.
+ * This applies to files added to the source branch *after* a daughter
+   branch was created: if previously no commit was made on the daughter
+   branch they will erroneously be added to the daughter branch in git.

+[[dbbackend]]
+Database Backend
+----------------
+
+'git-cvsserver' uses one database per Git head (i.e. CVS module) to
+store information about the repository to maintain consistent
+CVS revision numbers. The database needs to be
+updated (i.e. written to) after every commit.
+
+If the commit is done directly by using `git` (as opposed to
+using 'git-cvsserver') the update will need to happen on the
+next repository access by 'git-cvsserver', independent of
+access method and requested operation.
+
+That means that even if you offer only read access (e.g. by using
+the pserver method), 'git-cvsserver' should have write access to
+the database to work reliably (otherwise you need to make sure
+that the database is up-to-date any time 'git-cvsserver' is executed).
+
+By default it uses SQLite databases in the Git directory, named
+`gitcvs.<module_name>.sqlite`. Note that the SQLite backend creates
+temporary files in the same directory as the database file on
+write so it might not be enough to grant the users using
+'git-cvsserver' write access to the database file without granting
+them write access to the directory, too.
+
+The database can not be reliably regenerated in a
+consistent form after the branch it is tracking has changed.
+Example: For merged branches, 'git-cvsserver' only tracks
+one branch of development, and after a 'git merge' an
+incrementally updated database may track a different branch
+than a database regenerated from scratch, causing inconsistent
+CVS revision numbers. `git-cvsserver` has no way of knowing which
+branch it would have picked if it had been run incrementally
+pre-merge. So if you have to fully or partially (from old
+backup) regenerate the database, you should be suspicious
+of pre-existing CVS sandboxes.
+
+You can configure the database backend with the following
+configuration variables:
+
+Configuring database backend
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+'git-cvsserver' uses the Perl DBI module. Please also read
+its documentation if changing these variables, especially
+about `DBI->connect()`.
+
+gitcvs.dbName::
+	Database name. The exact meaning depends on the
+	selected database driver, for SQLite this is a filename.
+	Supports variable substitution (see below). May
+	not contain semicolons (`;`).
+	Default: '%Ggitcvs.%m.sqlite'
+
+gitcvs.dbDriver::
+	Used DBI driver. You can specify any available driver
+	for this here, but it might not work. cvsserver is tested
+	with 'DBD::SQLite', reported to work with
+	'DBD::Pg', and reported *not* to work with 'DBD::mysql'.
+	Please regard this as an experimental feature. May not
+	contain colons (`:`).
+	Default: 'SQLite'
+
+gitcvs.dbuser::
+	Database user. Only useful if setting `dbDriver`, since
+	SQLite has no concept of database users. Supports variable
+	substitution (see below).
+
+gitcvs.dbPass::
+	Database password.  Only useful if setting `dbDriver`, since
+	SQLite has no concept of database passwords.
+
+gitcvs.dbTableNamePrefix::
+	Database table name prefix.  Supports variable substitution
+	(see below).  Any non-alphabetic characters will be replaced
+	with underscores.
+
+All variables can also be set per access method, see <<configaccessmethod,above>>.
+
+Variable substitution
+^^^^^^^^^^^^^^^^^^^^^
+In `dbDriver` and `dbUser` you can use the following variables:
+
+%G::
+	Git directory name
+%g::
+	Git directory name, where all characters except for
+	alpha-numeric ones, `.`, and `-` are replaced with
+	`_` (this should make it easier to use the directory
+	name in a filename if wanted)
+%m::
+	CVS module/Git head name
+%a::
+	access method (one of "ext" or "pserver")
+%u::
+	Name of the user running 'git-cvsserver'.
+	If no name can be determined, the
+	numeric uid is used.
+
+ENVIRONMENT
+-----------
+
+These variables obviate the need for command-line options in some
+circumstances, allowing easier restricted usage through git-shell.
+
+GIT_CVSSERVER_BASE_PATH takes the place of the argument to --base-path.
+
+GIT_CVSSERVER_ROOT specifies a single-directory whitelist. The
+repository must still be configured to allow access through
+git-cvsserver, as described above.
+
+When these environment variables are set, the corresponding
+command-line arguments may not be used.

 Operations supported
 --------------------
 
 All the operations required for normal use are supported, including
 checkout, diff, status, update, log, add, remove, commit.
+
+Most CVS command arguments that read CVS tags or revision numbers
+(typically -r) work, and also support any git refspec
+(tag, branch, commit ID, etc).
+However, CVS revision numbers for non-default branches are not well
+emulated, and cvs log does not show tags or branches at
+all.  (Non-main-branch CVS revision numbers superficially resemble CVS
+revision numbers, but they actually encode a git commit ID directly,
+rather than represent the number of revisions since the branch point.)
+
+Note that there are two ways to checkout a particular branch.
+As described elsewhere on this page, the "module" parameter
+of cvs checkout is interpreted as a branch name, and it becomes
+the main branch.  It remains the main branch for a given sandbox
+even if you temporarily make another branch sticky with
+cvs update -r.  Alternatively, the -r argument can indicate
+some other branch to actually checkout, even though the module
+is still the "main" branch.  Tradeoffs (as currently
+implemented): Each new "module" creates a new database on disk with
+a history for the given module, and after the database is created,
+operations against that main branch are fast.  Or alternatively,
+-r doesn't take any extra disk space, but may be significantly slower for
+many operations, like cvs update.
+
+If you want to refer to a git refspec that has characters that are
+not allowed by CVS, you have two options.  First, it may just work
+to supply the git refspec directly to the appropriate CVS -r argument;
+some CVS clients don't seem to do much sanity checking of the argument.
+Second, if that fails, you can use a special character escape mechanism
+that only uses characters that are valid in CVS tags.  A sequence
+of 4 or 5 characters of the form (underscore (`"_"`), dash (`"-"`),
+one or two characters, and dash (`"-"`)) can encode various characters based
+on the one or two letters: `"s"` for slash (`"/"`), `"p"` for
+period (`"."`), `"u"` for underscore (`"_"`), or two hexadecimal digits
+for any byte value at all (typically an ASCII number, or perhaps a part
+of a UTF-8 encoded character).
+
 Legacy monitoring operations are not supported (edit, watch and related).
 Exports and tagging (tags and branches) are not supported at this stage.

-------------
+By default the server leaves the '-k' mode blank for all files,
+which causes the CVS client to treat them as a text files, subject
+to end-of-line conversion on some platforms.
 
-git-cvsserver depends on DBD::SQLite.
+You can make the server use the end-of-line conversion attributes to
+set the '-k' modes for files by setting the `gitcvs.usecrlfattr`
+config variable.  See linkgit:gitattributes[5] for more information
+about end-of-line conversion.
 
-Copyright and Authors
----------------------
+Alternatively, if `gitcvs.usecrlfattr` config is not enabled
+or the attributes do not allow automatic detection for a filename, then
+the server uses the `gitcvs.allBinary` config for the default setting.
+If `gitcvs.allBinary` is set, then file not otherwise
+specified will default to '-kb' mode. Otherwise the '-k' mode
+is left blank. But if `gitcvs.allBinary` is set to "guess", then
+the correct '-k' mode will be guessed based on the contents of
+the file.
 
-This program is copyright The Open University UK - 2006.
+For best consistency with 'cvs', it is probably best to override the
+defaults by setting `gitcvs.usecrlfattr` to true,
+and `gitcvs.allBinary` to "guess".

 DESCRIPTION
 -----------
 The command finds the most recent tag that is reachable from a

-the tag.  Otherwise, it suffixes the tag name with the number of
-additional commits and the abbreviated object name of the commit.
+commit.  If the tag points to the commit, then only the tag is
+shown.  Otherwise, it suffixes the tag name with the number of
+additional commits on top of the tagged object and the
+abbreviated object name of the most recent commit.
 
+By default (without --all or --tags) `git describe` only shows
+annotated tags.  For more information about creating annotated tags
+see the -a and -s options to linkgit:git-tag[1].
 
 OPTIONS
 -------
-<committish>::
-	The object name of the committish.
+<commit-ish>...::
+	Commit-ish object names to describe.  Defaults to HEAD if omitted.
+
+--dirty[=<mark>]::
+	Describe the working tree.
+	It means describe HEAD and appends <mark> (`-dirty` by
+	default) if the working tree is dirty.
 
 --all::
 	Instead of using only the annotated tags, use any ref
-	found in `.git/refs/`.
+	found in `refs/` namespace.  This option enables matching
+	any known branch, remote-tracking branch, or lightweight tag.
 
 --tags::
 	Instead of using only the annotated tags, use any tag
-	found in `.git/refs/tags`.
+	found in `refs/tags` namespace.  This option enables matching
+	a lightweight (non-annotated) tag.
+
+--contains::
+	Instead of finding the tag that predates the commit, find
+	the tag that comes after the commit, and thus contains it.
+	Automatically implies --tags.
 
 --abbrev=<n>::
-	Instead of using the default 8 hexadecimal digits as the
-	abbreviated object name, use <n> digits.
+	Instead of using the default 7 hexadecimal digits as the
+	abbreviated object name, use <n> digits, or as many digits
+	as needed to form a unique object name.  An <n> of 0
+	will suppress long format, only showing the closest tag.
 
 --candidates=<n>::
 	Instead of considering only the 10 most recent tags as
-	candidates to describe the input committish consider
+	candidates to describe the input commit-ish consider
 	up to <n> candidates.  Increasing <n> above 10 will take
 	slightly longer but may produce a more accurate result.
+	An <n> of 0 will cause only exact matches to be output.
+
+--exact-match::
+	Only output exact matches (a tag directly references the
+	supplied commit).  This is a synonym for --candidates=0.
 
 --debug::
 	Verbosely display information about the searching strategy
 	being employed to standard error.  The tag name will still
 	be printed to standard out.
 
+--long::
+	Always output the long format (the tag, the number of commits
+	and the abbreviated commit name) even when it matches a tag.
+	This is useful when you want to see parts of the commit object name
+	in "describe" output, even when the commit in question happens to be
+	a tagged version.  Instead of just emitting the tag name, it will
+	describe such a commit as v1.2-0-gdeadbee (0th commit since tag v1.2
+	that points at object deadbee....).
+
+--match <pattern>::
+	Only consider tags matching the given `glob(7)` pattern,
+	excluding the "refs/tags/" prefix.  This can be used to avoid
+	leaking private tags from the repository.
+
+--always::
+	Show uniquely abbreviated commit object as fallback.
+
+--first-parent::
+	Follow only the first parent commit upon seeing a merge commit.
+	This is useful when you wish to not match tags on branches merged
+	in the history of the target commit.

 Non-cached Mode
 ---------------
 The "non-cached" mode takes a different approach, and is potentially
 the more useful of the two in that what it does can't be emulated with
-a "git-write-tree" + "git-diff-tree". Thus that's the default mode.
+a 'git write-tree' + 'git diff-tree'. Thus that's the default mode.
 The non-cached version asks the question:
 
   show me the differences between HEAD and the currently checked out
   tree - index contents _and_ files that aren't up-to-date
 
 which is obviously a very useful question too, since that tells you what
-you *could* commit. Again, the output matches the "git-diff-tree -r"
+you *could* commit. Again, the output matches the 'git diff-tree -r'
 output to a tee, but with a twist.
 
 The twist is that if some file doesn't match the index, we don't have
 a backing store thing for it, and we use the magic "all-zero" sha1 to
 show that. So let's say that you have edited `kernel/sched.c`, but
-have not actually done a "git-update-index" on it yet - there is no
+have not actually done a 'git update-index' on it yet - there is no
 "object" associated with the new state, and you get:

+  :100644 100664 7476bb... 000000...      kernel/sched.c
 
 i.e., it shows that the tree has changed, and that `kernel/sched.c` has is
 not up-to-date and may contain new stuff. The all-zero sha1 means that to
 get the real diff, you need to look at the object in the working directory
 directly rather than do an object-to-object diff.

+	for the list of valid <tool> settings.
++
+If a diff tool is not specified, 'git difftool'
+will use the configuration variable `diff.tool`.  If the
+configuration variable `diff.tool` is not set, 'git difftool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `difftool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`difftool.kdiff3.path`. Otherwise, 'git difftool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known diff tools,
+'git difftool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `difftool.<tool>.cmd`.
++
+When 'git difftool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `diff.tool` configuration variable)
+the configured command line will be invoked with the following
+variables available: `$LOCAL` is set to the name of the temporary
+file containing the contents of the diff pre-image and `$REMOTE`
+is set to the name of the temporary file containing the contents
+of the diff post-image.  `$MERGED` is the name of the file which is
+being compared. `$BASE` is provided for compatibility
+with custom merge tool commands and has the same value as `$MERGED`.

++
+Specifying `--no-symlinks` instructs 'git difftool' to create copies
+instead.  `--no-symlinks` is the default on Windows.

+-x <command>::
+--extcmd=<command>::
+	Specify a custom command for viewing diffs.
+	'git-difftool' ignores the configured defaults and runs

+-g::
+--gui::
+	When 'git-difftool' is invoked with the `-g` or `--gui` option

+NAME
+----
+git-fast-export - Git data exporter
+
+
+SYNOPSIS
+--------
+[verse]
+'git fast-export [options]' | 'git fast-import'
+
+DESCRIPTION
+-----------
+This program dumps the given revisions in a form suitable to be piped
+into 'git fast-import'.
+
+You can use it as a human-readable bundle replacement (see
+linkgit:git-bundle[1]), or as a kind of an interactive
+'git filter-branch'.
+
+
+OPTIONS
+-------
+--progress=<n>::
+	Insert 'progress' statements every <n> objects, to be shown by
+	'git fast-import' during import.
+
+--signed-tags=(verbatim|warn|warn-strip|strip|abort)::
+	Specify how to handle signed tags.  Since any transformation
+	after the export can change the tag names (which can also happen
+	when excluding revisions) the signatures will not match.
++
+When asking to 'abort' (which is the default), this program will die
+when encountering a signed tag.  With 'strip', the tags will silently
+be made unsigned, with 'warn-strip' they will be made unsigned but a
+warning will be displayed, with 'verbatim', they will be silently
+exported and with 'warn', they will be exported, but you will see a
+warning.
+
+--tag-of-filtered-object=(abort|drop|rewrite)::
+	Specify how to handle tags whose tagged object is filtered out.
+	Since revisions and files to export can be limited by path,
+	tagged objects may be filtered completely.
++
+When asking to 'abort' (which is the default), this program will die
+when encountering such a tag.  With 'drop' it will omit such tags from
+the output.  With 'rewrite', if the tagged object is a commit, it will
+rewrite the tag to tag an ancestor commit (via parent rewriting; see
+linkgit:git-rev-list[1])
+
+-M::
+-C::
+	Perform move and/or copy detection, as described in the
+	linkgit:git-diff[1] manual page, and use it to generate
+	rename and copy commands in the output dump.
++
+Note that earlier versions of this command did not complain and
+produced incorrect results if you gave these options.
+
+--export-marks=<file>::
+	Dumps the internal marks table to <file> when complete.
+	Marks are written one per line as `:markid SHA-1`. Only marks
+	for revisions are dumped; marks for blobs are ignored.
+	Backends can use this file to validate imports after they
+	have been completed, or to save the marks table across
+	incremental runs.  As <file> is only opened and truncated
+	at completion, the same path can also be safely given to
+	--import-marks.
+	The file will not be written if no new object has been
+	marked/exported.
+
+--import-marks=<file>::
+	Before processing any input, load the marks specified in
+	<file>.  The input file must exist, must be readable, and
+	must use the same format as produced by --export-marks.
++
+Any commits that have already been marked will not be exported again.
+If the backend uses a similar --import-marks file, this allows for
+incremental bidirectional exporting of the repository by keeping the
+marks the same across runs.
+
+--fake-missing-tagger::
+	Some old repositories have tags without a tagger.  The
+	fast-import protocol was pretty strict about that, and did not
+	allow that.  So fake a tagger to be able to fast-import the
+	output.
+
+--use-done-feature::
+	Start the stream with a 'feature done' stanza, and terminate
+	it with a 'done' command.
+
+--no-data::
+	Skip output of blob objects and instead refer to blobs via
+	their original SHA-1 hash.  This is useful when rewriting the
+	directory structure or history of a repository without
+	touching the contents of individual files.  Note that the
+	resulting stream can only be used by a repository which
+	already contains the necessary objects.
+
+--full-tree::
+	This option will cause fast-export to issue a "deleteall"
+	directive for each commit followed by a full list of all files
+	in the commit (as opposed to just listing the files which are
+	different from the commit's first parent).
+
+--anonymize::
+	Anonymize the contents of the repository while still retaining
+	the shape of the history and stored tree.  See the section on
+	`ANONYMIZING` below.
+
+--refspec::
+	Apply the specified refspec to each ref exported. Multiple of them can
+	be specified.
+
+[<git-rev-list-args>...]::
+	A list of arguments, acceptable to 'git rev-parse' and
+	'git rev-list', that specifies the specific objects and references
+	to export.  For example, `master~10..master` causes the
+	current master reference to be exported along with all objects
+	added since its 10th ancestor commit.
+
+EXAMPLES
+--------
+
+-------------------------------------------------------------------
+$ git fast-export --all | (cd /empty/repository && git fast-import)
+-------------------------------------------------------------------
+
+This will export the whole repository and import it into the existing
+empty repository.  Except for reencoding commits that are not in
+UTF-8, it would be a one-to-one mirror.
+
+-----------------------------------------------------
+$ git fast-export master~5..master |
+	sed "s|refs/heads/master|refs/heads/other|" |
+	git fast-import
+-----------------------------------------------------
+
+This makes a new branch called 'other' from 'master~5..master'
+(i.e. if 'master' has linear history, it will take the last 5 commits).
+
+Note that this assumes that none of the blobs and commit messages
+referenced by that revision range contains the string
+'refs/heads/master'.
+
+
+ANONYMIZING
+-----------
+
+If the `--anonymize` option is given, git will attempt to remove all
+identifying information from the repository while still retaining enough
+of the original tree and history patterns to reproduce some bugs. The
+goal is that a git bug which is found on a private repository will
+persist in the anonymized repository, and the latter can be shared with
+git developers to help solve the bug.
+
+With this option, git will replace all refnames, paths, blob contents,
+commit and tag messages, names, and email addresses in the output with
+anonymized data.  Two instances of the same string will be replaced
+equivalently (e.g., two commits with the same author will have the same
+anonymized author in the output, but bear no resemblance to the original
+author string). The relationship between commits, branches, and tags is
+retained, as well as the commit timestamps (but the commit messages and
+refnames bear no resemblance to the originals). The relative makeup of
+the tree is retained (e.g., if you have a root tree with 10 files and 3
+trees, so will the output), but their names and the contents of the
+files will be replaced.
+
+If you think you have found a git bug, you can start by exporting an
+anonymized stream of the whole repository:
+
+---------------------------------------------------
+$ git fast-export --anonymize --all >anon-stream
+---------------------------------------------------
+
+Then confirm that the bug persists in a repository created from that
+stream (many bugs will not, as they really do depend on the exact
+repository contents):
+
+---------------------------------------------------
+$ git init anon-repo
+$ cd anon-repo
+$ git fast-import <../anon-stream
+$ ... test your bug ...
+---------------------------------------------------
+
+If the anonymized repository shows the bug, it may be worth sharing
+`anon-stream` along with a regular bug report. Note that the anonymized
+stream compresses very well, so gzipping it is encouraged. If you want
+to examine the stream to see that it does not contain any private data,
+you can peruse it directly before sending. You may also want to try:
+
+---------------------------------------------------
+$ perl -pe 's/\d+/X/g' <anon-stream | sort -u | less
+---------------------------------------------------
+
+which shows all of the unique lines (with numbers converted to "X", to
+collapse "User 0", "User 1", etc into "User X"). This produces a much
+smaller output, and it is usually easy to quickly confirm that there is
+no private data in the stream.
+
+
+Limitations
+-----------
+
+Since 'git fast-import' cannot tag trees, you will not be
+able to export the linux.git repository completely, as it contains
+a tag referencing a tree instead of a commit.

+
+--done::
+	Terminate with error if there is no `done` command at the end of

+
+Responses To Commands
+---------------------
+New objects written by fast-import are not available immediately.
+Most fast-import commands have no visible effect until the next
+checkpoint (or completion).  The frontend can send commands to
+fill fast-import's input pipe without worrying about how quickly
+they will take effect, which improves performance by simplifying
+scheduling.
+
+For some frontends, though, it is useful to be able to read back
+data from the current repository as it is being updated (for
+example when the source material describes objects in terms of
+patches to be applied to previously imported objects).  This can
+be accomplished by connecting the frontend and fast-import via
+bidirectional pipes:
+
+====
+	mkfifo fast-import-output
+	frontend <fast-import-output |
+	git fast-import >fast-import-output
+====
+
+A frontend set up this way can use `progress`, `get-mark`, `ls`, and
+`cat-blob` commands to read information from the import in progress.
+
+To avoid deadlock, such frontends must completely consume any
+pending output from `progress`, `ls`, `get-mark`, and `cat-blob` before
+performing writes to fast-import that might block.
+

+non-zero exit status and create a crash report in the top level of
+the Git repository it was importing into.  Crash reports contain
+a snapshot of the internal fast-import state as well as the most
+recent commands that lead up to the crash.
+
+All recent commands (including stream comments, file changes and
+progress commands) are shown in the command history within the crash
+report, but raw file data and commit messages are excluded from the
+crash report.  This exclusion saves space within the report file
+and reduces the amount of buffering that fast-import must perform
+during execution.
+
+After writing a crash report fast-import will close the current
+packfile and export the marks table.  This allows the frontend
+developer to inspect the repository state and resume the import from
+the point where it crashed.  The modified branches and tags are not
+updated during a crash, as the import did not complete successfully.
+Branch and tag information can be found in the crash report and
+must be applied manually if the update is needed.

 DESCRIPTION
 -----------

-The ref names and their object names of fetched refs are stored

-operation done by "git merge".
-
-When <refspec> stores the fetched result in tracking branches,
-the tags that point at these branches are automatically
-followed.  This is done by first fetching from the remote using
-the given <refspec>s, and if the repository has objects that are
-pointed by remote tags that it does not yet have, then fetch
-those missing tags.  If the other end has tags that point at
-branches you are not interested in, you will not get them.
-
+Fetch branches and/or tags (collectively, "refs") from one or more
+other repositories, along with the objects necessary to complete their
+histories.  Remote-tracking branches are updated (see the description
+of <refspec> below for ways to control this behavior).
+
+By default, any tag that points into the histories being fetched is
+also fetched; the effect is to fetch tags that
+point at branches that you are interested in.  This default behavior
+can be changed by using the --tags or --no-tags options or by
+configuring remote.<name>.tagOpt.  By using a refspec that fetches tags
+explicitly, you can fetch tags that do not point into branches you
+are interested in as well.
+
+'git fetch' can fetch from either a single named repository or URL,
+or from several repositories at once if <group> is given and
+there is a remotes.<group> entry in the configuration file.
+(See linkgit:git-config[1]).
+
+When no remote is specified, by default the `origin` remote will be used,
+unless there's an upstream branch configured for the current branch.
+
+The names of refs that are fetched, together with the object names
+they point at, are written to `.git/FETCH_HEAD`.  This information
+may be used by scripts or other git commands, such as linkgit:git-pull[1].

+CONFIGURED REMOTE-TRACKING BRANCHES[[CRTB]]
+-------------------------------------------
+
+You often interact with the same remote repository by
+regularly and repeatedly fetching from it.  In order to keep track
+of the progress of such a remote repository, `git fetch` allows you
+to configure `remote.<repository>.fetch` configuration variables.
+
+Typically such a variable may look like this:
+
+------------------------------------------------
+[remote "origin"]
+	fetch = +refs/heads/*:refs/remotes/origin/*
+------------------------------------------------
+
+This configuration is used in two ways:
+
+* When `git fetch` is run without specifying what branches
+  and/or tags to fetch on the command line, e.g. `git fetch origin`
+  or `git fetch`, `remote.<repository>.fetch` values are used as
+  the refspecs---they specify which refs to fetch and which local refs
+  to update.  The example above will fetch
+  all branches that exist in the `origin` (i.e. any ref that matches
+  the left-hand side of the value, `refs/heads/*`) and update the
+  corresponding remote-tracking branches in the `refs/remotes/origin/*`
+  hierarchy.
+
+* When `git fetch` is run with explicit branches and/or tags
+  to fetch on the command line, e.g. `git fetch origin master`, the
+  <refspec>s given on the command line determine what are to be
+  fetched (e.g. `master` in the example,
+  which is a short-hand for `master:`, which in turn means
+  "fetch the 'master' branch but I do not explicitly say what
+  remote-tracking branch to update with it from the command line"),
+  and the example command will
+  fetch _only_ the 'master' branch.  The `remote.<repository>.fetch`
+  values determine which
+  remote-tracking branch, if any, is updated.  When used in this
+  way, the `remote.<repository>.fetch` values do not have any
+  effect in deciding _what_ gets fetched (i.e. the values are not
+  used as refspecs when the command-line lists refspecs); they are
+  only used to decide _where_ the refs that are fetched are stored
+  by acting as a mapping.
+
+The latter use of the `remote.<repository>.fetch` values can be
+overridden by giving the `--refmap=<refspec>` parameter(s) on the
+command line.
+
+
+EXAMPLES
 --------
-gitlink:git-pull[1]
 
+* Update the remote-tracking branches:
++
+------------------------------------------------
+$ git fetch origin
+------------------------------------------------
++
+The above command copies all branches from the remote refs/heads/
+namespace and stores them to the local refs/remotes/origin/ namespace,
+unless the branch.<name>.fetch option is used to specify a non-default
+refspec.
+
+* Using refspecs explicitly:
++
+------------------------------------------------
+$ git fetch origin +pu:pu maint:tmp
+------------------------------------------------
++
+This updates (or creates, as necessary) branches `pu` and `tmp` in
+the local repository by fetching from the branches (respectively)
+`pu` and `maint` from the remote repository.
++
+The `pu` branch will be updated even if it is does not fast-forward,
+because it is prefixed with a plus sign; `tmp` will not be.
+
+* Peek at a remote's branch, without configuring the remote in your local
+repository:
++
+------------------------------------------------
+$ git fetch git://git.kernel.org/pub/scm/git/git.git maint
+$ git log FETCH_HEAD
+------------------------------------------------
++
+The first command fetches the `maint` branch from the repository at
+`git://git.kernel.org/pub/scm/git/git.git` and the second command uses
+`FETCH_HEAD` to examine the branch with linkgit:git-log[1].  The fetched
+objects will eventually be removed by git's built-in housekeeping (see
+linkgit:git-gc[1]).
+
+BUGS
+----
+Using --recurse-submodules can only fetch new commits in already checked
+out submodules right now. When e.g. upstream added a new submodule in the
+just fetched commits of the superproject the submodule itself can not be
+fetched, making it impossible to check out that submodule later without
+having to do a fetch again. This is expected to be fixed in a future Git
+version.

+git-filter-branch - Rewrite branches
+
+SYNOPSIS
+--------

+	[--index-filter <command>] [--parent-filter <command>]
+	[--msg-filter <command>] [--commit-filter <command>]
+	[--tag-name-filter <command>] [--subdirectory-filter <directory>]

+	[--] [<rev-list options>...]
+
+DESCRIPTION
+-----------
+Lets you rewrite Git revision history by rewriting the branches mentioned
+in the <rev-list options>, applying custom filters on each revision.
+Those filters can modify each tree (e.g. removing a file or running
+a perl rewrite on all files) or information about each commit.
+Otherwise, all information (including original commit times or merge
+information) will be preserved.
+
+The command will only rewrite the _positive_ refs mentioned in the
+command line (e.g. if you pass 'a..b', only 'b' will be rewritten).
+If you specify no filters, the commits will be recommitted without any
+changes, which would normally have no effect.  Nevertheless, this may be
+useful in the future for compensating for some Git bugs or such,
+therefore such a usage is permitted.
+
+*NOTE*: This command honors `.git/info/grafts` file and refs in
+the `refs/replace/` namespace.
+If you have any grafts or replacement refs defined, running this command
+will make them permanent.
+
+*WARNING*! The rewritten history will have different object names for all
+the objects and will not converge with the original branch.  You will not
+be able to easily push and distribute the rewritten branch on top of the
+original branch.  Please do not use this command if you do not know the
+full implications, and avoid using it anyway, if a simple single commit
+would suffice to fix your problem.  (See the "RECOVERING FROM UPSTREAM
+REBASE" section in linkgit:git-rebase[1] for further information about
+rewriting published history.)
+
+Always verify that the rewritten version is correct: The original refs,
+if different from the rewritten ones, will be stored in the namespace
+'refs/original/'.
+
+Note that since this operation is very I/O expensive, it might
+be a good idea to redirect the temporary directory off-disk with the
+'-d' option, e.g. on tmpfs.  Reportedly the speedup is very noticeable.
+
+
+Filters
+~~~~~~~
+
+The filters are applied in the order as listed below.  The <command>
+argument is always evaluated in the shell context using the 'eval' command
+(with the notable exception of the commit filter, for technical reasons).
+Prior to that, the $GIT_COMMIT environment variable will be set to contain
+the id of the commit being rewritten.  Also, GIT_AUTHOR_NAME,
+GIT_AUTHOR_EMAIL, GIT_AUTHOR_DATE, GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL,
+and GIT_COMMITTER_DATE are taken from the current commit and exported to
+the environment, in order to affect the author and committer identities of
+the replacement commit created by linkgit:git-commit-tree[1] after the
+filters have run.
+
+If any evaluation of <command> returns a non-zero exit status, the whole
+operation will be aborted.
+
+A 'map' function is available that takes an "original sha1 id" argument
+and outputs a "rewritten sha1 id" if the commit has been already
+rewritten, and "original sha1 id" otherwise; the 'map' function can
+return several ids on separate lines if your commit filter emitted
+multiple commits.
+
+
+OPTIONS
+-------
+
+--env-filter <command>::
+	This filter may be used if you only need to modify the environment
+	in which the commit will be performed.  Specifically, you might
+	want to rewrite the author/committer name/email/time environment
+	variables (see linkgit:git-commit-tree[1] for details).  Do not forget
+	to re-export the variables.
+
+--tree-filter <command>::
+	This is the filter for rewriting the tree and its contents.
+	The argument is evaluated in shell with the working
+	directory set to the root of the checked out tree.  The new tree
+	is then used as-is (new files are auto-added, disappeared files
+	are auto-removed - neither .gitignore files nor any other ignore
+	rules *HAVE ANY EFFECT*!).
+
+--index-filter <command>::
+	This is the filter for rewriting the index.  It is similar to the
+	tree filter but does not check out the tree, which makes it much
+	faster.  Frequently used with `git rm --cached
+	--ignore-unmatch ...`, see EXAMPLES below.  For hairy
+	cases, see linkgit:git-update-index[1].
+
+--parent-filter <command>::
+	This is the filter for rewriting the commit's parent list.
+	It will receive the parent string on stdin and shall output
+	the new parent string on stdout.  The parent string is in
+	the format described in linkgit:git-commit-tree[1]: empty for
+	the initial commit, "-p parent" for a normal commit and
+	"-p parent1 -p parent2 -p parent3 ..." for a merge commit.
+
+--msg-filter <command>::
+	This is the filter for rewriting the commit messages.
+	The argument is evaluated in the shell with the original
+	commit message on standard input; its standard output is
+	used as the new commit message.
+
+--commit-filter <command>::
+	This is the filter for performing the commit.
+	If this filter is specified, it will be called instead of the
+	'git commit-tree' command, with arguments of the form
+	"<TREE_ID> [(-p <PARENT_COMMIT_ID>)...]" and the log message on
+	stdin.  The commit id is expected on stdout.
++
+As a special extension, the commit filter may emit multiple
+commit ids; in that case, the rewritten children of the original commit will
+have all of them as parents.
++
+You can use the 'map' convenience function in this filter, and other
+convenience functions, too.  For example, calling 'skip_commit "$@"'
+will leave out the current commit (but not its changes! If you want
+that, use 'git rebase' instead).
++
+You can also use the `git_commit_non_empty_tree "$@"` instead of
+`git commit-tree "$@"` if you don't wish to keep commits with a single parent
+and that makes no change to the tree.
+
+--tag-name-filter <command>::
+	This is the filter for rewriting tag names. When passed,
+	it will be called for every tag ref that points to a rewritten
+	object (or to a tag object which points to a rewritten object).
+	The original tag name is passed via standard input, and the new
+	tag name is expected on standard output.
++
+The original tags are not deleted, but can be overwritten;
+use "--tag-name-filter cat" to simply update the tags.  In this
+case, be very careful and make sure you have the old tags
+backed up in case the conversion has run afoul.
++
+Nearly proper rewriting of tag objects is supported. If the tag has
+a message attached, a new tag object will be created with the same message,
+author, and timestamp. If the tag has a signature attached, the
+signature will be stripped. It is by definition impossible to preserve
+signatures. The reason this is "nearly" proper, is because ideally if
+the tag did not change (points to the same object, has the same name, etc.)
+it should retain any signature. That is not the case, signatures will always
+be removed, buyer beware. There is also no support for changing the
+author or timestamp (or the tag message for that matter). Tags which point
+to other tags will be rewritten to point to the underlying commit.
+
+--subdirectory-filter <directory>::
+	Only look at the history which touches the given subdirectory.
+	The result will contain that directory (and only that) as its
+	project root. Implies <<Remap_to_ancestor>>.
+
+--prune-empty::
+	Some kind of filters will generate empty commits, that left the tree
+	untouched.  This switch allow git-filter-branch to ignore such
+	commits.  Though, this switch only applies for commits that have one
+	and only one parent, it will hence keep merges points. Also, this
+	option is not compatible with the use of '--commit-filter'. Though you
+	just need to use the function 'git_commit_non_empty_tree "$@"' instead
+	of the `git commit-tree "$@"` idiom in your commit filter to make that
+	happen.
+
+--original <namespace>::
+	Use this option to set the namespace where the original commits
+	will be stored. The default value is 'refs/original'.
+
+-d <directory>::
+	Use this option to set the path to the temporary directory used for
+	rewriting.  When applying a tree filter, the command needs to
+	temporarily check out the tree to some directory, which may consume
+	considerable space in case of large projects.  By default it
+	does this in the '.git-rewrite/' directory but you can override
+	that choice by this parameter.
+
+-f::
+--force::
+	'git filter-branch' refuses to start with an existing temporary
+	directory or when there are already refs starting with
+	'refs/original/', unless forced.
+
+<rev-list options>...::
+	Arguments for 'git rev-list'.  All positive refs included by
+	these options are rewritten.  You may also specify options
+	such as '--all', but you must use '--' to separate them from
+	the 'git filter-branch' options. Implies <<Remap_to_ancestor>>.
+
+
+[[Remap_to_ancestor]]
+Remap to ancestor
+~~~~~~~~~~~~~~~~~
+
+By using linkgit:rev-list[1] arguments, e.g., path limiters, you can limit the
+set of revisions which get rewritten. However, positive refs on the command
+line are distinguished: we don't let them be excluded by such limiters. For
+this purpose, they are instead rewritten to point at the nearest ancestor that
+was not excluded.
+
+
+Examples
+--------
+
+Suppose you want to remove a file (containing confidential information
+or copyright violation) from all commits:
+
+-------------------------------------------------------
+git filter-branch --tree-filter 'rm filename' HEAD
+-------------------------------------------------------
+
+However, if the file is absent from the tree of some commit,
+a simple `rm filename` will fail for that tree and commit.
+Thus you may instead want to use `rm -f filename` as the script.
+
+Using `--index-filter` with 'git rm' yields a significantly faster
+version.  Like with using `rm filename`, `git rm --cached filename`
+will fail if the file is absent from the tree of a commit.  If you
+want to "completely forget" a file, it does not matter when it entered
+history, so we also add `--ignore-unmatch`:
+
+--------------------------------------------------------------------------
+git filter-branch --index-filter 'git rm --cached --ignore-unmatch filename' HEAD
+--------------------------------------------------------------------------
+
+Now, you will get the rewritten history saved in HEAD.
+
+To rewrite the repository to look as if `foodir/` had been its project
+root, and discard all other history:
+
+-------------------------------------------------------
+git filter-branch --subdirectory-filter foodir -- --all
+-------------------------------------------------------
+
+Thus you can, e.g., turn a library subdirectory into a repository of
+its own.  Note the `--` that separates 'filter-branch' options from
+revision options, and the `--all` to rewrite all branches and tags.
+
+To set a commit (which typically is at the tip of another
+history) to be the parent of the current initial commit, in
+order to paste the other history behind the current history:
+
+-------------------------------------------------------------------
+git filter-branch --parent-filter 'sed "s/^\$/-p <graft-id>/"' HEAD
+-------------------------------------------------------------------
+
+(if the parent string is empty - which happens when we are dealing with
+the initial commit - add graftcommit as a parent).  Note that this assumes
+history with a single root (that is, no merge without common ancestors
+happened).  If this is not the case, use:
+
+--------------------------------------------------------------------------
+git filter-branch --parent-filter \
+	'test $GIT_COMMIT = <commit-id> && echo "-p <graft-id>" || cat' HEAD
+--------------------------------------------------------------------------
+
+or even simpler:
+
+-----------------------------------------------
+echo "$commit-id $graft-id" >> .git/info/grafts
+git filter-branch $graft-id..HEAD
+-----------------------------------------------
+
+To remove commits authored by "Darl McBribe" from the history:
+
+------------------------------------------------------------------------------
+git filter-branch --commit-filter '
+	if [ "$GIT_AUTHOR_NAME" = "Darl McBribe" ];
+	then
+		skip_commit "$@";
+	else
+		git commit-tree "$@";
+	fi' HEAD
+------------------------------------------------------------------------------
+
+The function 'skip_commit' is defined as follows:
+
+--------------------------
+skip_commit()
+{
+	shift;
+	while [ -n "$1" ];
+	do
+		shift;
+		map "$1";
+		shift;
+	done;
+}
+--------------------------
+
+The shift magic first throws away the tree id and then the -p
+parameters.  Note that this handles merges properly! In case Darl
+committed a merge between P1 and P2, it will be propagated properly
+and all children of the merge will become merge commits with P1,P2
+as their parents instead of the merge commit.
+
+*NOTE* the changes introduced by the commits, and which are not reverted
+by subsequent commits, will still be in the rewritten branch. If you want
+to throw out _changes_ together with the commits, you should use the
+interactive mode of 'git rebase'.
+
+You can rewrite the commit log messages using `--msg-filter`.  For
+example, 'git svn-id' strings in a repository created by 'git svn' can
+be removed this way:
+
+-------------------------------------------------------
+git filter-branch --msg-filter '
+	sed -e "/^git-svn-id:/d"
+'
+-------------------------------------------------------
+
+If you need to add 'Acked-by' lines to, say, the last 10 commits (none
+of which is a merge), use this command:
+
+--------------------------------------------------------
+git filter-branch --msg-filter '
+	cat &&
+	echo "Acked-by: Bugs Bunny <bunny@bugzilla.org>"
+' HEAD~10..HEAD
+--------------------------------------------------------
+
+The `--env-filter` option can be used to modify committer and/or author
+identity.  For example, if you found out that your commits have the wrong
+identity due to a misconfigured user.email, you can make a correction,
+before publishing the project, like this:
+
+--------------------------------------------------------
+git filter-branch --env-filter '
+	if test "$GIT_AUTHOR_EMAIL" = "root@localhost"
+	then
+		GIT_AUTHOR_EMAIL=john@example.com
+		export GIT_AUTHOR_EMAIL
+	fi
+	if test "$GIT_COMMITTER_EMAIL" = "root@localhost"
+	then
+		GIT_COMMITTER_EMAIL=john@example.com
+		export GIT_COMMITTER_EMAIL
+	fi
+' -- --all
+--------------------------------------------------------
+
+To restrict rewriting to only part of the history, specify a revision
+range in addition to the new branch name.  The new branch name will
+point to the top-most revision that a 'git rev-list' of this range
+will print.
+
+Consider this history:
+
+------------------
+     D--E--F--G--H
+    /     /
+A--B-----C
+------------------
+
+To rewrite only commits D,E,F,G,H, but leave A, B and C alone, use:
+
+--------------------------------
+git filter-branch ... C..H
+--------------------------------
+
+To rewrite commits E,F,G,H, use one of these:
+
+----------------------------------------
+git filter-branch ... C..H --not D
+git filter-branch ... D..H --not C
+----------------------------------------
+
+To move the whole tree into a subdirectory, or remove it from there:
+
+---------------------------------------------------------------
+git filter-branch --index-filter \
+	'git ls-files -s | sed "s-\t\"*-&newsubdir/-" |
+		GIT_INDEX_FILE=$GIT_INDEX_FILE.new \
+			git update-index --index-info &&
+	 mv "$GIT_INDEX_FILE.new" "$GIT_INDEX_FILE"' HEAD
+---------------------------------------------------------------
+
+
+
+Checklist for Shrinking a Repository
+------------------------------------
+
+git-filter-branch can be used to get rid of a subset of files,
+usually with some combination of `--index-filter` and
+`--subdirectory-filter`.  People expect the resulting repository to
+be smaller than the original, but you need a few more steps to
+actually make it smaller, because Git tries hard not to lose your
+objects until you tell it to.  First make sure that:
+
+* You really removed all variants of a filename, if a blob was moved
+  over its lifetime.  `git log --name-only --follow --all -- filename`
+  can help you find renames.
+
+* You really filtered all refs: use `--tag-name-filter cat -- --all`
+  when calling git-filter-branch.
+
+Then there are two ways to get a smaller repository.  A safer way is
+to clone, that keeps your original intact.
+
+* Clone it with `git clone file:///path/to/repo`.  The clone
+  will not have the removed objects.  See linkgit:git-clone[1].  (Note
+  that cloning with a plain path just hardlinks everything!)
+
+If you really don't want to clone it, for whatever reasons, check the
+following points instead (in this order).  This is a very destructive
+approach, so *make a backup* or go back to cloning it.  You have been
+warned.
+
+* Remove the original refs backed up by git-filter-branch: say `git
+  for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git
+  update-ref -d`.
+
+* Expire all reflogs with `git reflog expire --expire=now --all`.
+
+* Garbage collect all unreferenced objects with `git gc --prune=now`
+  (or if your git-gc is not new enough to support arguments to
+  `--prune`, use `git repack -ad; git prune` instead).
+
+Notes
+-----
+
+git-filter-branch allows you to make complex shell-scripted rewrites
+of your Git history, but you probably don't need this flexibility if
+you're simply _removing unwanted data_ like large files or passwords.
+For those operations you may want to consider
+http://rtyley.github.io/bfg-repo-cleaner/[The BFG Repo-Cleaner],
+a JVM-based alternative to git-filter-branch, typically at least
+10-50x faster for those use-cases, and with quite different
+characteristics:
+
+* Any particular version of a file is cleaned exactly _once_. The BFG,
+  unlike git-filter-branch, does not give you the opportunity to
+  handle a file differently based on where or when it was committed
+  within your history. This constraint gives the core performance
+  benefit of The BFG, and is well-suited to the task of cleansing bad
+  data - you don't care _where_ the bad data is, you just want it
+  _gone_.
+
+* By default The BFG takes full advantage of multi-core machines,
+  cleansing commit file-trees in parallel. git-filter-branch cleans
+  commits sequentially (i.e. in a single-threaded manner), though it
+  _is_ possible to write filters that include their own parallelism,
+  in the scripts executed against each commit.
+
+* The http://rtyley.github.io/bfg-repo-cleaner/#examples[command options]
+  are much more restrictive than git-filter branch, and dedicated just
+  to the tasks of removing unwanted data- e.g:
+  `--strip-blobs-bigger-than 1M`.

+
+There are two ways to specify which commits to operate on.
+
+1. A single commit, <since>, specifies that the commits leading
+   to the tip of the current branch that are not in the history
+   that leads to the <since> to be output.
+
+2. Generic <revision range> expression (see "SPECIFYING
+   REVISIONS" section in linkgit:gitrevisions[7]) means the
+   commits in the specified range.
+
+The first rule takes precedence in the case of a single <commit>.  To
+apply the second rule, i.e., format everything since the beginning of
+history up until <commit>, use the '\--root' option: `git format-patch
+--root <commit>`.  If you want to format only <commit> itself, you
+can do this with `git format-patch -1 <commit>`.

+
+When sending a patch this way, most often you are sending your own

+should omit `From:` and `Date:` lines from the patch file.  The patch

+
+Checking for patch corruption
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Many mailers if not set up properly will corrupt whitespace.  Here are
+two common types of corruption:
+
+* Empty context lines that do not have _any_ whitespace.
+
+* Non-empty context lines that have one extra whitespace at the
+  beginning.
+
+One way to test if your MUA is set up correctly is:
+
+* Send the patch to yourself, exactly the way you would, except
+  with To: and Cc: lines that do not contain the list and
+  maintainer address.
+
+* Save that patch to a file in UNIX mailbox format.  Call it a.patch,
+  say.
+
+* Apply it:
+
+    $ git fetch <project> master:test-apply
+    $ git checkout test-apply
+    $ git reset --hard
+    $ git am a.patch
+
+If it does not apply correctly, there can be various reasons.
+
+* The patch itself does not apply cleanly.  That is _bad_ but
+  does not have much to do with your MUA.  You might want to rebase
+  the patch with linkgit:git-rebase[1] before regenerating it in
+  this case.
+
+* The MUA corrupted your patch; "am" would complain that
+  the patch does not apply.  Look in the .git/rebase-apply/ subdirectory and
+  see what 'patch' file contains and check for the common
+  corruption patterns mentioned above.
+
+* While at it, check the 'info' and 'final-commit' files as well.
+  If what is in 'final-commit' is not exactly what you would want to
+  see in the commit log message, it is very likely that the
+  receiver would end up hand editing the log message when applying
+  your patch.  Things like "Hi, this is my first patch.\n" in the
+  patch e-mail should come after the three-dash line that signals
+  the end of the commit message.
+
+MUA-SPECIFIC HINTS
+------------------
+Here are some hints on how to successfully submit patches inline using
+various mailers.
+
+GMail
+~~~~~
+GMail does not have any way to turn off line wrapping in the web
+interface, so it will mangle any emails that you send.  You can however
+use "git send-email" and send your patches through the GMail SMTP server, or
+use any IMAP email client to connect to the google IMAP server and forward
+the emails through that.
+
+For hints on using 'git send-email' to send your patches through the
+GMail SMTP server, see the EXAMPLE section of linkgit:git-send-email[1].
+
+For hints on submission using the IMAP interface, see the EXAMPLE
+section of linkgit:git-imap-send[1].
+
+Thunderbird
+~~~~~~~~~~~
+By default, Thunderbird will both wrap emails as well as flag
+them as being 'format=flowed', both of which will make the
+resulting email unusable by Git.
+
+There are three different approaches: use an add-on to turn off line wraps,
+configure Thunderbird to not mangle patches, or use
+an external editor to keep Thunderbird from mangling the patches.
+
+Approach #1 (add-on)
+^^^^^^^^^^^^^^^^^^^^
+
+Install the Toggle Word Wrap add-on that is available from
+https://addons.mozilla.org/thunderbird/addon/toggle-word-wrap/
+It adds a menu entry "Enable Word Wrap" in the composer's "Options" menu
+that you can tick off. Now you can compose the message as you otherwise do
+(cut + paste, 'git format-patch' | 'git imap-send', etc), but you have to
+insert line breaks manually in any text that you type.
+
+Approach #2 (configuration)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Three steps:
+
+1. Configure your mail server composition as plain text:
+   Edit...Account Settings...Composition & Addressing,
+   uncheck "Compose Messages in HTML".
+
+2. Configure your general composition window to not wrap.
++
+In Thunderbird 2:
+Edit..Preferences..Composition, wrap plain text messages at 0
++
+In Thunderbird 3:
+Edit..Preferences..Advanced..Config Editor.  Search for
+"mail.wrap_long_lines".
+Toggle it to make sure it is set to `false`. Also, search for
+"mailnews.wraplength" and set the value to 0.
+
+3. Disable the use of format=flowed:
+Edit..Preferences..Advanced..Config Editor.  Search for
+"mailnews.send_plaintext_flowed".
+Toggle it to make sure it is set to `false`.
+
+After that is done, you should be able to compose email as you
+otherwise would (cut + paste, 'git format-patch' | 'git imap-send', etc),
+and the patches will not be mangled.
+
+Approach #3 (external editor)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following Thunderbird extensions are needed:
+AboutConfig from http://aboutconfig.mozdev.org/ and
+External Editor from http://globs.org/articles.php?lng=en&pg=8
+
+1. Prepare the patch as a text file using your method of choice.
+
+2. Before opening a compose window, use Edit->Account Settings to
+   uncheck the "Compose messages in HTML format" setting in the
+   "Composition & Addressing" panel of the account to be used to
+   send the patch.
+
+3. In the main Thunderbird window, 'before' you open the compose
+   window for the patch, use Tools->about:config to set the
+   following to the indicated values:
++
+----------
+	mailnews.send_plaintext_flowed  => false
+	mailnews.wraplength             => 0
+----------
+
+4. Open a compose window and click the external editor icon.
+
+5. In the external editor window, read in the patch file and exit
+   the editor normally.
+
+Side note: it may be possible to do step 2 with
+about:config and the following settings but no one's tried yet.
+
+----------
+	mail.html_compose                       => false
+	mail.identity.default.compose_html      => false
+	mail.identity.id?.compose_html          => false
+----------
+
+There is a script in contrib/thunderbird-patch-inline which can help
+you include patches with Thunderbird in an easy way. To use it, do the
+steps above and then use the script as the external editor.
+
+KMail
+~~~~~
+This should help you to submit patches inline using KMail.
+
+1. Prepare the patch as a text file.
+
+2. Click on New Mail.
+
+3. Go under "Options" in the Composer window and be sure that
+   "Word wrap" is not set.
+
+4. Use Message -> Insert file... and insert the patch.
+
+5. Back in the compose window: add whatever other text you wish to the
+   message, complete the addressing and subject fields, and press send.
+
+

 SYNOPSIS

-'git-gc' [--prune]
+[verse]
+'git gc' [--aggressive] [--auto] [--quiet] [--prune=<date> | --no-prune] [--force]
 
 DESCRIPTION
 -----------
 Runs a number of housekeeping tasks within the current repository,
 such as compressing file revisions (to reduce disk space and increase
 performance) and removing unreachable objects which may have been
-created from prior invocations of gitlink:git-add[1].
+created from prior invocations of 'git add'.
 
 Users are encouraged to run this task on a regular basis within
 each repository to maintain good disk space utilization and good
 operating performance.
 
+Some git commands may automatically run 'git gc'; see the `--auto` flag
+below for details. If you know what you're doing and all you want is to
+disable this behavior permanently without further considerations, just do:
+
+----------------------
+$ git config --global gc.auto 0
+----------------------
+
 OPTIONS
 -------
 
---prune::
-	Usually `git-gc` packs refs, expires old reflog entries,
-	packs loose objects,
-	and removes old 'rerere' records.  Removal
-	of unreferenced loose objects is an unsafe operation
-	while other git operations are in progress, so it is not
-	done by default.  Pass this option if you want it, and only
-	when you know nobody else is creating new objects in the
-	repository at the same time (e.g. never use this option
-	in a cron script).
-
+--aggressive::
+	Usually 'git gc' runs very quickly while providing good disk
+	space utilization and performance.  This option will cause
+	'git gc' to more aggressively optimize the repository at the expense
+	of taking much more time.  The effects of this optimization are
+	persistent, so this option only needs to be used occasionally; every
+	few hundred changesets or so.
+
+--auto::
+	With this option, 'git gc' checks whether any housekeeping is
+	required; if not, it exits without performing any work.
+	Some git commands run `git gc --auto` after performing
+	operations that could create many loose objects.
++
+Housekeeping is required if there are too many loose objects or
+too many packs in the repository. If the number of loose objects
+exceeds the value of the `gc.auto` configuration variable, then
+all loose objects are combined into a single pack using
+`git repack -d -l`.  Setting the value of `gc.auto` to 0
+disables automatic packing of loose objects.
++
+If the number of packs exceeds the value of `gc.autoPackLimit`,
+then existing packs (except those marked with a `.keep` file)
+are consolidated into a single pack by using the `-A` option of
+'git repack'. Setting `gc.autoPackLimit` to 0 disables
+automatic consolidation of packs.
+
+--prune=<date>::
+	Prune loose objects older than date (default is 2 weeks ago,
+	overridable by the config variable `gc.pruneExpire`).
+	--prune=all prunes loose objects regardless of their age.
+	--prune is on by default.
+
+--no-prune::
+	Do not prune any loose objects.
+
+--quiet::
+	Suppress all progress reports.
+
+--force::
+	Force `git gc` to run even if there may be another `git gc`
+	instance running on this repository.

+
+Notes
+-----
+
+'git gc' tries very hard to be safe about the garbage it collects. In
+particular, it will keep not only objects referenced by your current set
+of branches and tags, but also objects referenced by the index,
+remote-tracking branches, refs saved by 'git filter-branch' in
+refs/original/, or reflogs (which may reference commits in branches
+that were later amended or rewound).
+
+If you are expecting some objects to be collected and they aren't, check
+all of those locations and decide whether it makes sense in your case to
+remove those references.
+
+HOOKS
+-----
+
+The 'git gc --auto' command will run the 'pre-auto-gc' hook.  See
+linkgit:githooks[5] for more information.

+Look for specified patterns in the tracked files in the work tree, blobs
+registered in the index file, or blobs in given tree objects.  Patterns
+are lists of one or more search expressions separated by newline

+	If set to true, enable '-n' option by default.
+
+grep.patternType::
+	Set the default matching behavior. Using a value of 'basic', 'extended',

+	'--fixed-strings', or '--perl-regexp' option accordingly, while the
+	value 'default' will return to the default matching behavior.
+

+NAME
+----
+git-gui - A portable graphical interface to Git
+
+SYNOPSIS
+--------
+[verse]
+'git gui' [<command>] [arguments]
+
+DESCRIPTION
+-----------
+A Tcl/Tk based graphical user interface to Git.  'git gui' focuses
+on allowing users to make changes to their repository by making
+new commits, amending existing ones, creating branches, performing
+local merges, and fetching/pushing to remote repositories.
+
+Unlike 'gitk', 'git gui' focuses on commit generation
+and single file annotation and does not show project history.
+It does however supply menu actions to start a 'gitk' session from
+within 'git gui'.
+
+'git gui' is known to work on all popular UNIX systems, Mac OS X,
+and Windows (under both Cygwin and MSYS).  To the extent possible
+OS specific user interface guidelines are followed, making 'git gui'
+a fairly native interface for users.
+
+COMMANDS
+--------
+blame::
+	Start a blame viewer on the specified file on the given
+	version (or working directory if not specified).
+
+browser::
+	Start a tree browser showing all files in the specified
+	commit (or 'HEAD' by default).  Files selected through the
+	browser are opened in the blame viewer.
+
+citool::
+	Start 'git gui' and arrange to make exactly one commit before
+	exiting and returning to the shell.  The interface is limited
+	to only commit actions, slightly reducing the application's
+	startup time and simplifying the menubar.
+
+version::
+	Display the currently running version of 'git gui'.
+
+
+Examples
+--------
+`git gui blame Makefile`::
+
+	Show the contents of the file 'Makefile' in the current
+	working directory, and provide annotations for both the
+	original author of each line, and who moved the line to its
+	current location.  The uncommitted file is annotated, and
+	uncommitted changes (if any) are explicitly attributed to
+	'Not Yet Committed'.
+
+`git gui blame v0.99.8 Makefile`::
+
+	Show the contents of 'Makefile' in revision 'v0.99.8'
+	and provide annotations for each line.  Unlike the above
+	example the file is read from the object database and not
+	the working directory.
+
+`git gui blame --line=100 Makefile`::
+
+	Loads annotations as described above and automatically
+	scrolls the view to center on line '100'.
+
+`git gui citool`::
+
+	Make one commit and return to the shell when it is complete.
+	This command returns a non-zero exit code if the window was
+	closed in any way other than by making a commit.
+
+`git gui citool --amend`::
+
+	Automatically enter the 'Amend Last Commit' mode of
+	the interface.
+
+`git gui citool --nocommit`::
+
+	Behave as normal citool, but instead of making a commit
+	simply terminate with a zero exit code. It still checks
+	that the index does not contain any unmerged entries, so
+	you can use it as a GUI version of linkgit:git-mergetool[1]
+
+`git citool`::
+
+	Same as `git gui citool` (above).
+
+`git gui browser maint`::
+
+	Show a browser for the tree of the 'maint' branch.  Files
+	selected in the browser can be viewed with the internal
+	blame viewer.
+
+SEE ALSO
+--------
+linkgit:gitk[1]::
+	The Git repository browser.  Shows branches, commit history
+	and file differences.  gitk is the utility started by
+	'git gui''s Repository Visualize actions.
+
+Other
+-----
+'git gui' is actually maintained as an independent project, but stable
+versions are distributed as part of the Git suite for the convenience
+of end users.
+
+A 'git gui' development repository can be obtained from:
+
+  git clone git://repo.or.cz/git-gui.git
+
+or
+
+  git clone http://repo.or.cz/r/git-gui.git
+

+SYNOPSIS

+'git help' [-a|--all] [-g|--guide]
+	   [-i|--info|-m|--man|-w|--web] [COMMAND|GUIDE]
+
+DESCRIPTION
+-----------
+
+With no options and no COMMAND or GUIDE given, the synopsis of the 'git'
+command and a list of the most commonly used Git commands are printed
+on the standard output.
+
+If the option '--all' or '-a' is given, all available commands are
+printed on the standard output.
+
+If the option '--guide' or '-g' is given, a list of the useful
+Git guides is also printed on the standard output.
+
+If a command, or a guide, is given, a manual page for that command or
+guide is brought up. The 'man' program is used by default for this
+purpose, but this can be overridden by other options or configuration
+variables.
+
+Note that `git --help ...` is identical to `git help ...` because the
+former is internally converted into the latter.
+
+To display the linkgit:git[1] man page, use `git help git`.
+
+This page can be displayed with 'git help help' or `git help --help`
+
+OPTIONS
+-------
+-a::
+--all::
+	Prints all the available commands on the standard output. This
+	option overrides any given command or guide name.
+
+-g::
+--guides::
+	Prints a list of useful guides on the standard output. This
+	option overrides any given command or guide name.
+
+-i::
+--info::
+	Display manual page for the command in the 'info' format. The
+	'info' program will be used for that purpose.
+
+-m::
+--man::
+	Display manual page for the command in the 'man' format. This
+	option may be used to override a value set in the
+	'help.format' configuration variable.
++
+By default the 'man' program will be used to display the manual page,
+but the 'man.viewer' configuration variable may be used to choose
+other display programs (see below).
+
+-w::
+--web::
+	Display manual page for the command in the 'web' (HTML)
+	format. A web browser will be used for that purpose.
++
+The web browser can be specified using the configuration variable
+'help.browser', or 'web.browser' if the former is not set. If none of
+these config variables is set, the 'git web{litdd}browse' helper script
+(called by 'git help') will pick a suitable default. See
+linkgit:git-web{litdd}browse[1] for more information about this.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+help.format
+~~~~~~~~~~~
+
+If no command-line option is passed, the 'help.format' configuration
+variable will be checked. The following values are supported for this
+variable; they make 'git help' behave as their corresponding command-
+line option:
+
+* "man" corresponds to '-m|--man',
+* "info" corresponds to '-i|--info',
+* "web" or "html" correspond to '-w|--web'.
+
+help.browser, web.browser and browser.<tool>.path
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
+be checked if the 'web' format is chosen (either by command-line
+option or configuration variable). See '-w|--web' in the OPTIONS
+section above and linkgit:git-web{litdd}browse[1].
+
+man.viewer
+~~~~~~~~~~
+
+The 'man.viewer' configuration variable will be checked if the 'man'
+format is chosen. The following values are currently supported:
+
+* "man": use the 'man' program as usual,
+* "woman": use 'emacsclient' to launch the "woman" mode in emacs
+(this only works starting with emacsclient versions 22),
+* "konqueror": use 'kfmclient' to open the man page in a new konqueror
+tab (see 'Note about konqueror' below).
+
+Values for other tools can be used if there is a corresponding
+'man.<tool>.cmd' configuration entry (see below).
+
+Multiple values may be given to the 'man.viewer' configuration
+variable. Their corresponding programs will be tried in the order
+listed in the configuration file.
+
+For example, this configuration:
+
+------------------------------------------------
+	[man]
+		viewer = konqueror
+		viewer = woman
+------------------------------------------------
+
+will try to use konqueror first. But this may fail (for example, if
+DISPLAY is not set) and in that case emacs' woman mode will be tried.
+
+If everything fails, or if no viewer is configured, the viewer specified
+in the GIT_MAN_VIEWER environment variable will be tried.  If that
+fails too, the 'man' program will be tried anyway.
+
+man.<tool>.path
+~~~~~~~~~~~~~~~
+
+You can explicitly provide a full path to your preferred man viewer by
+setting the configuration variable 'man.<tool>.path'. For example, you
+can configure the absolute path to konqueror by setting
+'man.konqueror.path'. Otherwise, 'git help' assumes the tool is
+available in PATH.
+
+man.<tool>.cmd
+~~~~~~~~~~~~~~
+
+When the man viewer, specified by the 'man.viewer' configuration
+variables, is not among the supported ones, then the corresponding
+'man.<tool>.cmd' configuration variable will be looked up. If this
+variable exists then the specified tool will be treated as a custom
+command and a shell eval will be used to run the command with the man
+page passed as arguments.
+
+Note about konqueror
+~~~~~~~~~~~~~~~~~~~~
+
+When 'konqueror' is specified in the 'man.viewer' configuration
+variable, we launch 'kfmclient' to try to open the man page on an
+already opened konqueror in a new tab if possible.
+
+For consistency, we also try such a trick if 'man.konqueror.path' is
+set to something like 'A_PATH_TO/konqueror'. That means we will try to
+launch 'A_PATH_TO/kfmclient' instead.
+
+If you really want to use 'konqueror', then you can use something like
+the following:
+
+------------------------------------------------
+	[man]
+		viewer = konq
+
+	[man "konq"]
+		cmd = A_PATH_TO/konqueror
+------------------------------------------------
+
+Note about git config --global
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that all these configuration variables should probably be set
+using the '--global' flag, for example like this:
+
+------------------------------------------------
+$ git config --global help.format web
+$ git config --global web.browser firefox
+------------------------------------------------
+
+as they are probably more user specific than repository specific.
+See linkgit:git-config[1] for more information about this.

+git-http-backend(1)
+===================
+
+NAME
+----
+git-http-backend - Server side implementation of Git over HTTP
+
+SYNOPSIS
+--------
+[verse]
+'git http-backend'
+
+DESCRIPTION
+-----------
+A simple CGI program to serve the contents of a Git repository to Git
+clients accessing the repository over http:// and https:// protocols.
+The program supports clients fetching using both the smart HTTP protocol
+and the backwards-compatible dumb HTTP protocol, as well as clients
+pushing using the smart HTTP protocol.
+
+It verifies that the directory has the magic file
+"git-daemon-export-ok", and it will refuse to export any Git directory
+that hasn't explicitly been marked for export this way (unless the
+GIT_HTTP_EXPORT_ALL environmental variable is set).
+
+By default, only the `upload-pack` service is enabled, which serves
+'git fetch-pack' and 'git ls-remote' clients, which are invoked from
+'git fetch', 'git pull', and 'git clone'.  If the client is authenticated,
+the `receive-pack` service is enabled, which serves 'git send-pack'
+clients, which is invoked from 'git push'.
+
+SERVICES
+--------
+These services can be enabled/disabled using the per-repository
+configuration file:
+
+http.getanyfile::
+	This serves Git clients older than version 1.6.6 that are unable to use the
+	upload pack service.  When enabled, clients are able to read
+	any file within the repository, including objects that are
+	no longer reachable from a branch but are still present.
+	It is enabled by default, but a repository can disable it
+	by setting this configuration item to `false`.
+
+http.uploadpack::
+	This serves 'git fetch-pack' and 'git ls-remote' clients.
+	It is enabled by default, but a repository can disable it
+	by setting this configuration item to `false`.
+
+http.receivepack::
+	This serves 'git send-pack' clients, allowing push.  It is
+	disabled by default for anonymous users, and enabled by
+	default for users authenticated by the web server.  It can be
+	disabled by setting this item to `false`, or enabled for all
+	users, including anonymous users, by setting it to `true`.
+
+URL TRANSLATION
+---------------
+To determine the location of the repository on disk, 'git http-backend'
+concatenates the environment variables PATH_INFO, which is set
+automatically by the web server, and GIT_PROJECT_ROOT, which must be set
+manually in the web server configuration.  If GIT_PROJECT_ROOT is not
+set, 'git http-backend' reads PATH_TRANSLATED, which is also set
+automatically by the web server.
+
+EXAMPLES
+--------
+All of the following examples map `http://$hostname/git/foo/bar.git`
+to `/var/www/git/foo/bar.git`.
+
+Apache 2.x::
+	Ensure mod_cgi, mod_alias, and mod_env are enabled, set
+	GIT_PROJECT_ROOT (or DocumentRoot) appropriately, and
+	create a ScriptAlias to the CGI:
++
+----------------------------------------------------------------
+SetEnv GIT_PROJECT_ROOT /var/www/git
+SetEnv GIT_HTTP_EXPORT_ALL
+ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
+----------------------------------------------------------------
++
+To enable anonymous read access but authenticated write access,
+require authorization for both the initial ref advertisement (which we
+detect as a push via the service parameter in the query string), and the
+receive-pack invocation itself:
++
+----------------------------------------------------------------
+RewriteCond %{QUERY_STRING} service=git-receive-pack [OR]
+RewriteCond %{REQUEST_URI} /git-receive-pack$
+RewriteRule ^/git/ - [E=AUTHREQUIRED:yes]
+
+<LocationMatch "^/git/">
+	Order Deny,Allow
+	Deny from env=AUTHREQUIRED
+
+	AuthType Basic
+	AuthName "Git Access"
+	Require group committers
+	Satisfy Any
+	...
+</LocationMatch>
+----------------------------------------------------------------
++
+If you do not have `mod_rewrite` available to match against the query
+string, it is sufficient to just protect `git-receive-pack` itself,
+like:
++
+----------------------------------------------------------------
+<LocationMatch "^/git/.*/git-receive-pack$">
+	AuthType Basic
+	AuthName "Git Access"
+	Require group committers
+	...
+</LocationMatch>
+----------------------------------------------------------------
++
+In this mode, the server will not request authentication until the
+client actually starts the object negotiation phase of the push, rather
+than during the initial contact.  For this reason, you must also enable
+the `http.receivepack` config option in any repositories that should
+accept a push. The default behavior, if `http.receivepack` is not set,
+is to reject any pushes by unauthenticated users; the initial request
+will therefore report `403 Forbidden` to the client, without even giving
+an opportunity for authentication.
++
+To require authentication for both reads and writes, use a Location
+directive around the repository, or one of its parent directories:
++
+----------------------------------------------------------------
+<Location /git/private>
+	AuthType Basic
+	AuthName "Private Git Access"
+	Require group committers
+	...
+</Location>
+----------------------------------------------------------------
++
+To serve gitweb at the same url, use a ScriptAliasMatch to only
+those URLs that 'git http-backend' can handle, and forward the
+rest to gitweb:
++
+----------------------------------------------------------------
+ScriptAliasMatch \
+	"(?x)^/git/(.*/(HEAD | \
+			info/refs | \
+			objects/(info/[^/]+ | \
+				 [0-9a-f]{2}/[0-9a-f]{38} | \
+				 pack/pack-[0-9a-f]{40}\.(pack|idx)) | \
+			git-(upload|receive)-pack))$" \
+	/usr/libexec/git-core/git-http-backend/$1
+
+ScriptAlias /git/ /var/www/cgi-bin/gitweb.cgi/
+----------------------------------------------------------------
++
+To serve multiple repositories from different linkgit:gitnamespaces[7] in a
+single repository:
++
+----------------------------------------------------------------
+SetEnvIf Request_URI "^/git/([^/]*)" GIT_NAMESPACE=$1
+ScriptAliasMatch ^/git/[^/]*(.*) /usr/libexec/git-core/git-http-backend/storage.git$1
+----------------------------------------------------------------
+
+Accelerated static Apache 2.x::
+	Similar to the above, but Apache can be used to return static
+	files that are stored on disk.	On many systems this may
+	be more efficient as Apache can ask the kernel to copy the
+	file contents from the file system directly to the network:
++
+----------------------------------------------------------------
+SetEnv GIT_PROJECT_ROOT /var/www/git
+
+AliasMatch ^/git/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$          /var/www/git/$1
+AliasMatch ^/git/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$ /var/www/git/$1
+ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
+----------------------------------------------------------------
++
+This can be combined with the gitweb configuration:
++
+----------------------------------------------------------------
+SetEnv GIT_PROJECT_ROOT /var/www/git
+
+AliasMatch ^/git/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$          /var/www/git/$1
+AliasMatch ^/git/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$ /var/www/git/$1
+ScriptAliasMatch \
+	"(?x)^/git/(.*/(HEAD | \
+			info/refs | \
+			objects/info/[^/]+ | \
+			git-(upload|receive)-pack))$" \
+	/usr/libexec/git-core/git-http-backend/$1
+ScriptAlias /git/ /var/www/cgi-bin/gitweb.cgi/
+----------------------------------------------------------------
+
+Lighttpd::
+	Ensure that `mod_cgi`, `mod_alias`, `mod_auth`, `mod_setenv` are
+	loaded, then set `GIT_PROJECT_ROOT` appropriately and redirect
+	all requests to the CGI:
++
+----------------------------------------------------------------
+alias.url += ( "/git" => "/usr/lib/git-core/git-http-backend" )
+$HTTP["url"] =~ "^/git" {
+	cgi.assign = ("" => "")
+	setenv.add-environment = (
+		"GIT_PROJECT_ROOT" => "/var/www/git",
+		"GIT_HTTP_EXPORT_ALL" => ""
+	)
+}
+----------------------------------------------------------------
++
+To enable anonymous read access but authenticated write access:
++
+----------------------------------------------------------------
+$HTTP["querystring"] =~ "service=git-receive-pack" {
+	include "git-auth.conf"
+}
+$HTTP["url"] =~ "^/git/.*/git-receive-pack$" {
+	include "git-auth.conf"
+}
+----------------------------------------------------------------
++
+where `git-auth.conf` looks something like:
++
+----------------------------------------------------------------
+auth.require = (
+	"/" => (
+		"method" => "basic",
+		"realm" => "Git Access",
+		"require" => "valid-user"
+	       )
+)
+# ...and set up auth.backend here
+----------------------------------------------------------------
++
+To require authentication for both reads and writes:
++
+----------------------------------------------------------------
+$HTTP["url"] =~ "^/git/private" {
+	include "git-auth.conf"
+}
+----------------------------------------------------------------
+
+
+ENVIRONMENT
+-----------
+'git http-backend' relies upon the CGI environment variables set
+by the invoking web server, including:
+
+* PATH_INFO (if GIT_PROJECT_ROOT is set, otherwise PATH_TRANSLATED)
+* REMOTE_USER
+* REMOTE_ADDR
+* CONTENT_TYPE
+* QUERY_STRING
+* REQUEST_METHOD
+
+The GIT_HTTP_EXPORT_ALL environmental variable may be passed to
+'git-http-backend' to bypass the check for the "git-daemon-export-ok"
+file in each repository before allowing export of that repository.
+
+The `GIT_HTTP_MAX_REQUEST_BUFFER` environment variable (or the
+`http.maxRequestBuffer` config variable) may be set to change the
+largest ref negotiation request that git will handle during a fetch; any
+fetch requiring a larger buffer will not succeed.  This value should not
+normally need to be changed, but may be helpful if you are fetching from
+a repository with an extremely large number of refs.  The value can be
+specified with a unit (e.g., `100M` for 100 megabytes). The default is
+10 megabytes.
+
+The backend process sets GIT_COMMITTER_NAME to '$REMOTE_USER' and
+GIT_COMMITTER_EMAIL to '$\{REMOTE_USER}@http.$\{REMOTE_ADDR\}',
+ensuring that any reflogs created by 'git-receive-pack' contain some
+identifying information of the remote user who performed the push.
+
+All CGI environment variables are available to each of the hooks
+invoked by the 'git-receive-pack'.

+	using libcurl.  Ignored if Git was built with the NO_OPENSSL option
+	set.
 
 
 CONFIGURATION
 -------------
 
-git-imap-send requires the following values in the repository
-configuration file (shown with examples):
+To use the tool, imap.folder and either imap.tunnel or imap.host must be set
+to appropriate values.
+
+Variables
+~~~~~~~~~
+
+imap.folder::
+	The folder to drop the mails into, which is typically the Drafts
+	folder. For example: "INBOX.Drafts", "INBOX/Drafts" or
+	"[Gmail]/Drafts". Required.
+
+imap.tunnel::
+	Command used to setup a tunnel to the IMAP server through which
+	commands will be piped instead of using a direct network connection
+	to the server. Required when imap.host is not set.
+
+imap.host::
+	A URL identifying the server. Use a `imap://` prefix for non-secure
+	connections and a `imaps://` prefix for secure connections.
+	Ignored when imap.tunnel is set, but required otherwise.
+
+imap.user::
+	The username to use when logging in to the server.
+
+imap.pass::
+	The password to use when logging in to the server.
+
+imap.port::
+	An integer port number to connect to on the server.
+	Defaults to 143 for imap:// hosts and 993 for imaps:// hosts.
+	Ignored when imap.tunnel is set.
+
+imap.sslverify::
+	A boolean to enable/disable verification of the server certificate
+	used by the SSL/TLS connection. Default is `true`. Ignored when
+	imap.tunnel is set.
+
+imap.preformattedHTML::
+	A boolean to enable/disable the use of html encoding when sending
+	a patch.  An html encoded patch will be bracketed with <pre>
+	and have a content type of text/html.  Ironically, enabling this
+	option causes Thunderbird to send the patch as a plain/text,
+	format=fixed email.  Default is `false`.
+
+imap.authMethod::
+	Specify authenticate method for authentication with IMAP server.
+	If Git was built with the NO_CURL option, or if your curl version is older
+	than 7.34.0, or if you're running git-imap-send with the `--no-curl`
+	option, the only supported method is 'CRAM-MD5'. If this is not set
+	then 'git imap-send' uses the basic IMAP plaintext LOGIN command.
+
+Examples
+~~~~~~~~
+
+Using tunnel mode:
 
 ..........................
 [imap]
-    Folder = "INBOX.Drafts"
+    folder = "INBOX.Drafts"
+    tunnel = "ssh -q -C user@example.com /usr/bin/imapd ./Maildir 2> /dev/null"
+..........................
 
-[imap]
-    Tunnel = "ssh -q user@server.com /usr/bin/imapd ./Maildir 2> /dev/null"
+Using direct mode:
 
+.........................
 [imap]
-    Host = imap.server.com
-    User = bob
-    Pass = pwd
-    Port = 143
-..........................
+    folder = "INBOX.Drafts"
+    host = imap://imap.example.com
+    user = bob
+    pass = p4ssw0rd
+.........................
 
+Using direct mode with SSL:
 
-BUGS
-----
-Doesn't handle lines starting with "From " in the message body.
+.........................
+[imap]
+    folder = "INBOX.Drafts"
+    host = imaps://imap.example.com

+EXAMPLE
+-------
+To submit patches using GMail's IMAP interface, first, edit your ~/.gitconfig
+to specify your account settings:
 
-Documentation
---------------
-Documentation by Mike McCormack
+---------
+[imap]
+	folder = "[Gmail]/Drafts"
+	host = imaps://imap.gmail.com
+	user = user@gmail.com
+	port = 993
+	sslverify = false
+---------
+
+You might need to instead use: folder = "[Google Mail]/Drafts" if you get an error
+that the "Folder doesn't exist".
+
+Once the commits are ready to be sent, run the following command:
+
+  $ git format-patch --cover-letter -M --stdout origin/master | git imap-send
+
+Just make sure to disable line wrapping in the email client (GMail's web
+interface will wrap lines no matter what, so you need to use a real
+IMAP client).
+
+CAUTION
+-------
+It is still your responsibility to make sure that the email message
+sent by your email program meets the standards of your project.
+Many projects do not like patches to be attached.  Some mail
+agents will transform patches (e.g. wrap lines, send them as
+format=flowed) in ways that make them fail.  You will get angry
+flames ridiculing you if you don't check this.
+
+Thunderbird in particular is known to be problematic.  Thunderbird
+users may wish to visit this web page for more information:

++
+If this is reinitialization, the repository will be moved to the specified path.

+Use permissions reported by umask(2). The default, when `--shared` is not

+
+'group' (or 'true')::
+
+Make the repository group-writable, (and g+sx, since the git group may be not
+the primary group of all users). This is used to loosen the permissions of an
+otherwise safe umask(2) value. Note that the umask still applies to the other
+permission bits (e.g. if umask is '0022', using 'group' will not remove read
+privileges from other (non-group) users). See '0xxx' for how to exactly specify
+the repository permissions.
 
- - 'umask' (or 'false'): Use permissions reported by umask(2). The default,

-   the git group may be not the primary group of all users).
+Same as 'group', but make the repository readable by all users.

-   readable by all users.
+'0xxx'::
 
-By default, the configuration flag receive.denyNonFastforward is enabled
+'0xxx' is an octal number and each file will have mode '0xxx'. '0xxx' will
+override users' umask(2) value (and not only loosen permissions as 'group' and
+'all' does). '0640' will create a repository which is group-readable, but not
+group-writable or accessible to others. '0660' will create a repo that is
+readable and writable to the current user and group, but inaccessible to others.
+--
+
+By default, the configuration flag `receive.denyNonFastForwards` is enabled
 in shared repositories, so that you cannot force a non fast-forwarding push
 into it.

+does not exist, it will be created.

+
+SYNOPSIS

+[verse]
+'git interpret-trailers' [--trim-empty] [(--trailer <token>[(=|:)<value>])...] [<file>...]
+
+DESCRIPTION
+-----------
+Help adding 'trailers' lines, that look similar to RFC 822 e-mail
+headers, at the end of the otherwise free-form part of a commit
+message.
+
+This command reads some patches or commit messages from either the
+<file> arguments or the standard input if no <file> is specified. Then
+this command applies the arguments passed using the `--trailer`
+option, if any, to the commit message part of each input file. The
+result is emitted on the standard output.
+
+Some configuration variables control the way the `--trailer` arguments
+are applied to each commit message and the way any existing trailer in
+the commit message is changed. They also make it possible to
+automatically add some trailers.
+
+By default, a '<token>=<value>' or '<token>:<value>' argument given
+using `--trailer` will be appended after the existing trailers only if
+the last trailer has a different (<token>, <value>) pair (or if there
+is no existing trailer). The <token> and <value> parts will be trimmed
+to remove starting and trailing whitespace, and the resulting trimmed
+<token> and <value> will appear in the message like this:
+
+------------------------------------------------
+token: value
+------------------------------------------------
+
+This means that the trimmed <token> and <value> will be separated by
+`': '` (one colon followed by one space).
+
+By default the new trailer will appear at the end of all the existing
+trailers. If there is no existing trailer, the new trailer will appear
+after the commit message part of the output, and, if there is no line
+with only spaces at the end of the commit message part, one blank line
+will be added before the new trailer.
+
+Existing trailers are extracted from the input message by looking for
+a group of one or more lines that contain a colon (by default), where
+the group is preceded by one or more empty (or whitespace-only) lines.
+The group must either be at the end of the message or be the last
+non-whitespace lines before a line that starts with '---'. Such three
+minus signs start the patch part of the message.
+
+When reading trailers, there can be whitespaces before and after the
+token, the separator and the value. There can also be whitespaces
+inside the token and the value.
+
+Note that 'trailers' do not follow and are not intended to follow many
+rules for RFC 822 headers. For example they do not follow the line
+folding rules, the encoding rules and probably many other rules.
+
+OPTIONS
+-------
+--trim-empty::
+	If the <value> part of any trailer contains only whitespace,
+	the whole trailer will be removed from the resulting message.
+	This apply to existing trailers as well as new trailers.
+
+--trailer <token>[(=|:)<value>]::
+	Specify a (<token>, <value>) pair that should be applied as a
+	trailer to the input messages. See the description of this
+	command.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+trailer.separators::
+	This option tells which characters are recognized as trailer
+	separators. By default only ':' is recognized as a trailer
+	separator, except that '=' is always accepted on the command
+	line for compatibility with other git commands.
++
+The first character given by this option will be the default character
+used when another separator is not specified in the config for this
+trailer.
++
+For example, if the value for this option is "%=$", then only lines
+using the format '<token><sep><value>' with <sep> containing '%', '='
+or '$' and then spaces will be considered trailers. And '%' will be
+the default separator used, so by default trailers will appear like:
+'<token>% <value>' (one percent sign and one space will appear between
+the token and the value).
+
+trailer.where::
+	This option tells where a new trailer will be added.
++
+This can be `end`, which is the default, `start`, `after` or `before`.
++
+If it is `end`, then each new trailer will appear at the end of the
+existing trailers.
++
+If it is `start`, then each new trailer will appear at the start,
+instead of the end, of the existing trailers.
++
+If it is `after`, then each new trailer will appear just after the
+last trailer with the same <token>.
++
+If it is `before`, then each new trailer will appear just before the
+first trailer with the same <token>.
+
+trailer.ifexists::
+	This option makes it possible to choose what action will be
+	performed when there is already at least one trailer with the
+	same <token> in the message.
++
+The valid values for this option are: `addIfDifferentNeighbor` (this
+is the default), `addIfDifferent`, `add`, `overwrite` or `doNothing`.
++
+With `addIfDifferentNeighbor`, a new trailer will be added only if no
+trailer with the same (<token>, <value>) pair is above or below the line
+where the new trailer will be added.
++
+With `addIfDifferent`, a new trailer will be added only if no trailer
+with the same (<token>, <value>) pair is already in the message.
++
+With `add`, a new trailer will be added, even if some trailers with
+the same (<token>, <value>) pair are already in the message.
++
+With `replace`, an existing trailer with the same <token> will be
+deleted and the new trailer will be added. The deleted trailer will be
+the closest one (with the same <token>) to the place where the new one
+will be added.
++
+With `doNothing`, nothing will be done; that is no new trailer will be
+added if there is already one with the same <token> in the message.
+
+trailer.ifmissing::
+	This option makes it possible to choose what action will be
+	performed when there is not yet any trailer with the same
+	<token> in the message.
++
+The valid values for this option are: `add` (this is the default) and
+`doNothing`.
++
+With `add`, a new trailer will be added.
++
+With `doNothing`, nothing will be done.
+
+trailer.<token>.key::
+	This `key` will be used instead of <token> in the trailer. At
+	the end of this key, a separator can appear and then some
+	space characters. By default the only valid separator is ':',
+	but this can be changed using the `trailer.separators` config
+	variable.
++
+If there is a separator, then the key will be used instead of both the
+<token> and the default separator when adding the trailer.
+
+trailer.<token>.where::
+	This option takes the same values as the 'trailer.where'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <token>.
+
+trailer.<token>.ifexist::
+	This option takes the same values as the 'trailer.ifexist'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <token>.
+
+trailer.<token>.ifmissing::
+	This option takes the same values as the 'trailer.ifmissing'
+	configuration variable and it overrides what is specified by
+	that option for trailers with the specified <token>.
+
+trailer.<token>.command::
+	This option can be used to specify a shell command that will
+	be called to automatically add or modify a trailer with the
+	specified <token>.
++
+When this option is specified, the behavior is as if a special
+'<token>=<value>' argument were added at the beginning of the command
+line, where <value> is taken to be the standard output of the
+specified command with any leading and trailing whitespace trimmed
+off.
++
+If the command contains the `$ARG` string, this string will be
+replaced with the <value> part of an existing trailer with the same
+<token>, if any, before the command is launched.
++
+If some '<token>=<value>' arguments are also passed on the command
+line, when a 'trailer.<token>.command' is configured, the command will
+also be executed for each of these arguments. And the <value> part of
+these arguments, if any, will be used to replace the `$ARG` string in
+the command.
+
+EXAMPLES
+--------
+
+* Configure a 'sign' trailer with a 'Signed-off-by' key, and then
+  add two of these trailers to a message:
++
+------------
+$ git config trailer.sign.key "Signed-off-by"
+$ cat msg.txt
+subject
+
+message
+$ cat msg.txt | git interpret-trailers --trailer 'sign: Alice <alice@example.com>' --trailer 'sign: Bob <bob@example.com>'
+subject
+
+message
+
+Signed-off-by: Alice <alice@example.com>
+Signed-off-by: Bob <bob@example.com>
+------------
+
+* Extract the last commit as a patch, and add a 'Cc' and a
+  'Reviewed-by' trailer to it:
++
+------------
+$ git format-patch -1
+0001-foo.patch
+$ git interpret-trailers --trailer 'Cc: Alice <alice@example.com>' --trailer 'Reviewed-by: Bob <bob@example.com>' 0001-foo.patch >0001-bar.patch
+------------
+
+* Configure a 'sign' trailer with a command to automatically add a
+  'Signed-off-by: ' with the author information only if there is no
+  'Signed-off-by: ' already, and show how it works:
++
+------------
+$ git config trailer.sign.key "Signed-off-by: "
+$ git config trailer.sign.ifmissing add
+$ git config trailer.sign.ifexists doNothing
+$ git config trailer.sign.command 'echo "$(git config user.name) <$(git config user.email)>"'
+$ git interpret-trailers <<EOF
+> EOF
+
+Signed-off-by: Bob <bob@example.com>
+$ git interpret-trailers <<EOF
+> Signed-off-by: Alice <alice@example.com>
+> EOF
+
+Signed-off-by: Alice <alice@example.com>
+------------
+
+* Configure a 'fix' trailer with a key that contains a '#' and no
+  space after this character, and show how it works:
++
+------------
+$ git config trailer.separators ":#"
+$ git config trailer.fix.key "Fix #"
+$ echo "subject" | git interpret-trailers --trailer fix=42
+subject
+
+Fix #42
+------------
+
+* Configure a 'see' trailer with a command to show the subject of a
+  commit that is related, and show how it works:
++
+------------
+$ git config trailer.see.key "See-also: "
+$ git config trailer.see.ifExists "replace"
+$ git config trailer.see.ifMissing "doNothing"
+$ git config trailer.see.command "git log -1 --oneline --format=\"%h (%s)\" --abbrev-commit --abbrev=14 \$ARG"
+$ git interpret-trailers <<EOF
+> subject
+> 
+> message
+> 
+> see: HEAD~2
+> EOF
+subject
+
+message
+
+See-also: fe3187489d69c4 (subject of related commit)
+------------
+
+* Configure a commit template with some trailers with empty values
+  (using sed to show and keep the trailing spaces at the end of the
+  trailers), then configure a commit-msg hook that uses
+  'git interpret-trailers' to remove trailers with empty values and
+  to add a 'git-version' trailer:
++
+------------
+$ sed -e 's/ Z$/ /' >commit_template.txt <<EOF
+> ***subject***
+> 
+> ***message***
+> 
+> Fixes: Z
+> Cc: Z
+> Reviewed-by: Z
+> Signed-off-by: Z
+> EOF
+$ git config commit.template commit_template.txt
+$ cat >.git/hooks/commit-msg <<EOF
+> #!/bin/sh
+> git interpret-trailers --trim-empty --trailer "git-version: \$(git describe)" "\$1" > "\$1.new"
+> mv "\$1.new" "\$1"
+> EOF

 SYNOPSIS

+[verse]

 DESCRIPTION
 -----------
 Shows the commit logs.
 
-The command takes options applicable to the gitlink:git-rev-list[1]
+The command takes options applicable to the `git rev-list`
 command to control what is shown and how, and options applicable to
-the gitlink:git-diff-tree[1] commands to control how the changes
+the `git diff-*` commands to control how the changes
 each commit introduces are shown.
 
-This manual page describes only the most frequently used options.
-
 
 OPTIONS
 -------
 
-include::pretty-formats.txt[]
-
--<n>::
-	Limits the number of commits to show.
+--follow::
+	Continue listing the history of a file beyond renames
+	(works only for a single file).
+
+--no-decorate::
+--decorate[=short|full|no]::
+	Print out the ref names of any commits that are shown. If 'short' is
+	specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
+	'refs/remotes/' will not be printed. If 'full' is specified, the
+	full ref name (including prefix) will be printed. The default option
+	is 'short'.
+
+--source::
+	Print out the ref name given on the command line by which each
+	commit was reached.
+
+--use-mailmap::
+	Use mailmap file to map author and committer names and email
+	addresses to canonical real names and email addresses. See
+	linkgit:git-shortlog[1].
+
+--full-diff::
+	Without this flag, `git log -p <path>...` shows commits that
+	touch the specified paths, and diffs about the same specified
+	paths.  With this, the full diff is shown for commits that touch
+	the specified paths; this means that "<path>..." limits only
+	commits, and doesn't limit diff for those commits.
++
+Note that this affects all diff-based output types, e.g. those
+produced by `--stat`, etc.
+
+--log-size::
+	Include a line ``log size <number>'' in the output for each commit,
+	where <number> is the length of that commit's message in bytes.
+	Intended to speed up tools that read log messages from `git log`
+	output by allowing them to allocate space in advance.
+
+-L <start>,<end>:<file>::
+-L :<funcname>:<file>::
+	Trace the evolution of the line range given by "<start>,<end>"
+	(or the function name regex <funcname>) within the <file>.  You may
+	not give any pathspec limiters.  This is currently limited to
+	a walk starting from a single revision, i.e., you may only
+	give zero or one positive revision arguments.
+	You can specify this option more than once.
++
+include::line-range-format.txt[]
+
+<revision range>::
+	Show only commits in the specified revision range.  When no
+	<revision range> is specified, it defaults to `HEAD` (i.e. the
+	whole history leading to the current commit).  `origin..HEAD`
+	specifies all the commits reachable from the current commit
+	(i.e. `HEAD`), but not from `origin`. For a complete list of
+	ways to spell <revision range>, see the 'Specifying Ranges'
+	section of linkgit:gitrevisions[7].
+
+[\--] <path>...::
+	Show only commits that are enough to explain how the files
+	that match the specified paths came to be.  See 'History
+	Simplification' below for details and other simplification
+	modes.
++
+Paths may need to be prefixed with ``\-- '' to separate them from
+options or the revision range, when confusion arises.
+
+include::rev-list-options.txt[]
 
-<since>..<until>::
-	Show only commits between the named two commits.  When
-	either <since> or <until> is omitted, it defaults to
-	`HEAD`, i.e. the tip of the current branch.
-	For a more complete list of ways to spell <since>
-	and <until>, see "SPECIFYING REVISIONS" section in
-	gitlink:git-rev-parse[1].
+include::pretty-formats.txt[]
 
--p::
-	Show the change the commit introduces in a patch form.
+COMMON DIFF OPTIONS
+-------------------
 
-<paths>...::
-	Show only commits that affect the specified paths.
+:git-log: 1
+include::diff-options.txt[]
 
+include::diff-generate-patch.txt[]
 
-Examples
+EXAMPLES
 --------
-git log --no-merges::
+`git log --no-merges`::
 
 	Show the whole commit history, but skip any merges
 
-git log v2.6.12.. include/scsi drivers/scsi::
+`git log v2.6.12.. include/scsi drivers/scsi`::
 
 	Show all commits since version 'v2.6.12' that changed any file
-	in the include/scsi or drivers/scsi subdirectories
+	in the `include/scsi` or `drivers/scsi` subdirectories
 
-git log --since="2 weeks ago" \-- gitk::
+`git log --since="2 weeks ago" -- gitk`::
 
 	Show the changes during the last two weeks to the file 'gitk'.
-	The "--" is necessary to avoid confusion with the *branch* named
+	The ``--'' is necessary to avoid confusion with the *branch* named
 	'gitk'
 
-git log -r --name-status release..test::
+`git log --name-status release..test`::
 
 	Show the commits that are in the "test" branch but not yet
 	in the "release" branch, along with the list of paths
 	each commit modifies.
 
-Discussion
-----------
+`git log --follow builtin/rev-list.c`::
 
-include::i18n.txt[]
+	Shows the commits that changed `builtin/rev-list.c`, including
+	those commits that occurred before the file was given its
+	present name.
+
+`git log --branches --not --remotes=origin`::
+
+	Shows all commits that are in any of local branches but not in
+	any of remote-tracking branches for 'origin' (what you have that
+	origin doesn't).
+
+`git log master --not --remotes=*/master`::
+
+	Shows all commits that are in local master but not in any remote
+	repository master branches.
 
+`git log -p -m --first-parent`::
 
-Author
-------
-Written by Linus Torvalds <torvalds@osdl.org>
+	Shows the history including change diffs, but only from the
+	``main branch'' perspective, skipping commits that come from merged
+	branches, and showing full diffs of changes introduced by the merges.
+	This makes sense only when following a strict policy of merging all
+	topic branches when staying on a single integration branch.
 
-Documentation
---------------
-Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>.
+`git log -L '/int main/',/^}/:main.c`::
+
+	Shows how the function `main()` in the file `main.c` evolved
+	over time.
+
+`git log -3`::
+
+	Limits the number of commits to show to 3.
+
+DISCUSSION
+----------
+
+include::i18n.txt[]
+
+CONFIGURATION
+-------------
+
+See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
+for settings related to diff generation.
+
+format.pretty::
+	Default for the `--format` option.  (See 'Pretty Formats' above.)
+	Defaults to `medium`.
+
+i18n.logOutputEncoding::
+	Encoding to use when displaying logs.  (See 'Discussion' above.)
+	Defaults to the value of `i18n.commitEncoding` if set, and UTF-8
+	otherwise.
+
+log.date::
+	Default format for human-readable dates.  (Compare the
+	`--date` option.)  Defaults to "default", which means to write
+	dates like `Sat May 8 19:35:34 2010 -0500`.
+
+log.follow::
+	If a single <path> is given to git log, it will act as
+	if the `--follow` option was also used.  This has the same
+	limitations as `--follow`, i.e. it cannot be used to follow
+	multiple files and does not work well on non-linear history.
+
+log.showRoot::
+	If `false`, `git log` and related commands will not treat the
+	initial commit as a big creation event.  Any root commits in
+	`git log -p` output would be shown without a diff attached.
+	The default is `true`.
+
+mailmap.*::
+	See linkgit:git-shortlog[1].
+
+notes.displayRef::
+	Which refs, in addition to the default set by `core.notesRef`
+	or 'GIT_NOTES_REF', to read notes from when showing commit
+	messages with the `log` family of commands.  See
+	linkgit:git-notes[1].
++
+May be an unabbreviated ref name or a glob and may be specified
+multiple times.  A warning will be issued for refs that do not exist,
+but a glob that does not match any refs is silently ignored.
++
+This setting can be disabled by the `--no-notes` option,
+overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
+and overridden by the `--notes=<ref>` option.

-NAME
-----
-git-lost-found - Recover lost refs that luckily have not yet been pruned
-
-SYNOPSIS
---------
-'git-lost-found'
-
-DESCRIPTION
------------
-Finds dangling commits and tags from the object database, and
-creates refs to them in .git/lost-found/ directory.  Commits and
-tags that dereference to commits go to .git/lost-found/commit
-and others are stored in .git/lost-found/other directory.
-
-
-OUTPUT
-------
-One line description from the commit and tag found along with
-their object name are printed on the standard output.
-
-
-EXAMPLE
--------
-
-Suppose you run 'git tag -f' and mistyped the tag to overwrite.
-The ref to your tag is overwritten, but until you run 'git
-prune', it is still there.

 DESCRIPTION
 -----------
 
-"git-merge-base" finds as good a common ancestor as possible between
-the two commits. That is, given two commits A and B 'git-merge-base A
-B' will output a commit which is reachable from both A and B through
-the parent relationship.
+'git merge-base' finds best common ancestor(s) between two commits to use
+in a three-way merge.  One common ancestor is 'better' than another common
+ancestor if the latter is an ancestor of the former.  A common ancestor
+that does not have any better common ancestor is a 'best common
+ancestor', i.e. a 'merge base'.  Note that there can be more than one
+merge base for a pair of commits.
 
-Given a selection of equally good common ancestors it should not be
-relied on to decide in any particular way.
+OPERATION MODES
+---------------
 
-The "git-merge-base" algorithm is still in flux - use the source...
+As the most common special case, specifying only two commits on the
+command line means computing the merge base between the given two commits.
+
+More generally, among the two commits to compute the merge base from,
+one is specified by the first commit argument on the command line;
+the other commit is a (possibly hypothetical) commit that is a merge
+across all the remaining commits on the command line.
+
+As a consequence, the 'merge base' is not necessarily contained in each of the
+commit arguments if more than two commits are specified. This is different
+from linkgit:git-show-branch[1] when used with the `--merge-base` option.
+
+--octopus::
+	Compute the best common ancestors of all supplied commits,
+	in preparation for an n-way merge.  This mimics the behavior
+	of 'git show-branch --merge-base'.
+
+--independent::
+	Instead of printing merge bases, print a minimal subset of
+	the supplied commits with the same ancestors.  In other words,
+	among the commits given, list those which cannot be reached
+	from any other.  This mimics the behavior of 'git show-branch
+	--independent'.
+
+--is-ancestor::
+	Check if the first <commit> is an ancestor of the second <commit>,
+	and exit with status 0 if true, or with status 1 if not.
+	Errors are signaled by a non-zero status that is not 1.
+
+--fork-point::

+DISCUSSION
+----------
+
+Given two commits 'A' and 'B', `git merge-base A B` will output a commit
+which is reachable from both 'A' and 'B' through the parent relationship.
+
+For example, with this topology:
+
+		 o---o---o---B
+		/
+	---o---1---o---o---o---A
+
+the merge base between 'A' and 'B' is '1'.
+
+Given three commits 'A', 'B' and 'C', `git merge-base A B C` will compute the
+merge base between 'A' and a hypothetical commit 'M', which is a merge
+between 'B' and 'C'.  For example, with this topology:
+
+	       o---o---o---o---C
+	      /
+	     /   o---o---o---B
+	    /   /
+	---2---1---o---o---o---A
+
+the result of `git merge-base A B C` is '1'.  This is because the
+equivalent topology with a merge commit 'M' between 'B' and 'C' is:
+
+
+	       o---o---o---o---o
+	      /                 \
+	     /   o---o---o---o---M
+	    /   /
+	---2---1---o---o---o---A
+
+and the result of `git merge-base A M` is '1'.  Commit '2' is also a
+common ancestor between 'A' and 'M', but '1' is a better common ancestor,
+because '2' is an ancestor of '1'.  Hence, '2' is not a merge base.
 
-Author

-Written by Linus Torvalds <torvalds@osdl.org>
+The result of `git merge-base --octopus A B C` is '2', because '2' is
+the best common ancestor of all commits.
 
-Documentation
---------------
-Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>.
+When the history involves criss-cross merges, there can be more than one
+'best' common ancestor for two commits.  For example, with this topology:
+
+       ---1---o---A
+	   \ /
+	    X
+	   / \
+       ---2---o---o---B
+
+both '1' and '2' are merge-bases of A and B.  Neither one is better than
+the other (both are 'best' merge bases).  When the `--all` option is not given,
+it is unspecified which best one is output.
+
+A common idiom to check "fast-forward-ness" between two commits A
+and B is (or at least used to be) to compute the merge base between
+A and B, and check if it is the same as A, in which case, A is an
+ancestor of B.  You will see this idiom used often in older scripts.
+
+	A=$(git rev-parse --verify A)
+	if test "$A" = "$(git merge-base A B)"
+	then
+		... A is an ancestor of B ...
+	fi
+
+In modern git, you can say this in a more direct way:
+
+	if git merge-base --is-ancestor A B
+	then
+		... A is an ancestor of B ...
+	fi
+
+instead.
+
+Discussion on fork-point mode
+-----------------------------
+
+After working on the `topic` branch created with `git checkout -b
+topic origin/master`, the history of remote-tracking branch
+`origin/master` may have been rewound and rebuilt, leading to a
+history of this shape:
+
+			 o---B1
+			/
+	---o---o---B2--o---o---o---B (origin/master)
+		\
+		 B3
+		  \
+		   Derived (topic)
+
+where `origin/master` used to point at commits B3, B2, B1 and now it
+points at B, and your `topic` branch was started on top of it back
+when `origin/master` was at B3. This mode uses the reflog of
+`origin/master` to find B3 as the fork point, so that the `topic`
+can be rebased on top of the updated `origin/master` by:
+
+    $ fork_point=$(git merge-base --fork-point origin/master topic)
+    $ git rebase --onto origin/master $fork_point topic

+Incorporates changes from the named commits (since the time their

+branch.  This command is used by 'git pull' to incorporate changes
+from another repository and can be used by hand to merge changes
+from one branch into another.
+
+Assume the following history exists and the current branch is
+"`master`":
+
+------------
+	  A---B---C topic
+	 /
+    D---E---F---G master
+------------
+
+Then "`git merge topic`" will replay the changes made on the
+`topic` branch since it diverged from `master` (i.e., `E`) until
+its current commit (`C`) on top of `master`, and record the result
+in a new commit along with the names of the two parent commits and
+a log message from the user describing the changes.
+
+------------
+	  A---B---C topic
+	 /         \
+    D---E---F---G---H master
+------------
+
+The second syntax (<msg> `HEAD` <commit>...) is supported for
+historical reasons.  Do not use it from the command line or in
+new scripts.  It is the same as `git merge -m <msg> <commit>...`.
+
+The third syntax ("`git merge --abort`") can only be run after the
+merge has resulted in conflicts. 'git merge --abort' will abort the
+merge process and try to reconstruct the pre-merge state. However,
+if there were uncommitted changes when the merge started (and
+especially if those changes were further modified after the merge
+was started), 'git merge --abort' will in some cases be unable to
+reconstruct the original (pre-merge) changes. Therefore:
+
+*Warning*: Running 'git merge' with non-trivial uncommitted changes is
+discouraged: while possible, it may leave you in a state that is hard to
+back out of in the case of a conflict.

+
+
+PRE-MERGE CHECKS
+----------------
+
+Before applying outside changes, you should get your own work in
+good shape and committed locally, so it will not be clobbered if
+there are conflicts.  See also linkgit:git-stash[1].
+'git pull' and 'git merge' will stop without doing anything when
+local uncommitted changes overlap with files that 'git pull'/'git
+merge' may need to update.
+
+To avoid recording unrelated changes in the merge commit,
+'git pull' and 'git merge' will also abort if there are any changes
+registered in the index relative to the `HEAD` commit.  (One
+exception is when the changed index entries are in the state that
+would result from the merge already.)
+
+If all named commits are already ancestors of `HEAD`, 'git merge'
+will exit early with the message "Already up-to-date."
+
+FAST-FORWARD MERGE
+------------------
+
+Often the current branch head is an ancestor of the named commit.
+This is the most common case especially when invoked from 'git
+pull': you are tracking an upstream repository, you have committed
+no local changes, and now you want to update to a newer upstream
+revision.  In this case, a new commit is not needed to store the
+combined history; instead, the `HEAD` (along with the index) is
+updated to point at the named commit, without creating an extra
+merge commit.
+
+This behavior can be suppressed with the `--no-ff` option.
+
+TRUE MERGE
+----------
+
+Except in a fast-forward merge (see above), the branches to be
+merged must be tied together by a merge commit that has both of them
+as its parents.
+
+A merged version reconciling the changes from all branches to be
+merged is committed, and your `HEAD`, index, and working tree are
+updated to it.  It is possible to have modifications in the working
+tree as long as they do not overlap; the update will preserve them.
+
+When it is not obvious how to reconcile the changes, the following
+happens:
+
+1. The `HEAD` pointer stays the same.
+2. The `MERGE_HEAD` ref is set to point to the other branch head.
+3. Paths that merged cleanly are updated both in the index file and
+   in your working tree.
+4. For conflicting paths, the index file records up to three
+   versions: stage 1 stores the version from the common ancestor,
+   stage 2 from `HEAD`, and stage 3 from `MERGE_HEAD` (you
+   can inspect the stages with `git ls-files -u`).  The working
+   tree files contain the result of the "merge" program; i.e. 3-way
+   merge results with familiar conflict markers `<<<` `===` `>>>`.
+5. No other changes are made.  In particular, the local
+   modifications you had before you started merge will stay the
+   same and the index entries for them stay as they were,
+   i.e. matching `HEAD`.
 
-<head>::
-	Our branch head commit.  This has to be `HEAD`, so new
-	syntax does not require it
+If you tried a merge which resulted in complex conflicts and
+want to start over, you can recover with `git merge --abort`.
 
-<remote>::
-	Other branch head merged into our branch.  You need at
-	least one <remote>.  Specifying more than one <remote>
-	obviously means you are trying an Octopus.
+MERGING TAG
+-----------
 
-include::merge-strategies.txt[]
+When merging an annotated (and possibly signed) tag, Git always
+creates a merge commit even if a fast-forward merge is possible, and
+the commit message template is prepared with the tag message.
+Additionally, if the tag is signed, the signature check is reported
+as a comment in the message template. See also linkgit:git-tag[1].
 
+When you want to just integrate with the work leading to the commit
+that happens to be tagged, e.g. synchronizing with an upstream
+release point, you may not want to make an unnecessary merge commit.
 
-If you tried a merge which resulted in a complex conflicts and
-would want to start over, you can recover with
-gitlink:git-reset[1].
-
-
-HOW MERGE WORKS
----------------
-
-A merge is always between the current `HEAD` and one or more
-remote branch heads, and the index file must exactly match the
-tree of `HEAD` commit (i.e. the contents of the last commit) when
-it happens.  In other words, `git-diff --cached HEAD` must
-report no changes.
-
-[NOTE]
-This is a bit of lie.  In certain special cases, your index are
-allowed to be different from the tree of `HEAD` commit.  The most
-notable case is when your `HEAD` commit is already ahead of what
-is being merged, in which case your index can have arbitrary
-difference from your `HEAD` commit.  Otherwise, your index entries
-are allowed have differences from your `HEAD` commit that match
-the result of trivial merge (e.g. you received the same patch
-from external source to produce the same result as what you are
-merging).  For example, if a path did not exist in the common
-ancestor and your head commit but exists in the tree you are
-merging into your repository, and if you already happen to have
-that path exactly in your index, the merge does not have to
-fail.
-
-Otherwise, merge will refuse to do any harm to your repository
-(that is, it may fetch the objects from remote, and it may even
-update the local branch used to keep track of the remote branch
-with `git pull remote rbranch:lbranch`, but your working tree,
-`.git/HEAD` pointer and index file are left intact).
-
-You may have local modifications in the working tree files.  In
-other words, `git-diff` is allowed to report changes.
-However, the merge uses your working tree as the working area,
-and in order to prevent the merge operation from losing such
-changes, it makes sure that they do not interfere with the
-merge. Those complex tables in read-tree documentation define
-what it means for a path to "interfere with the merge".  And if
-your local modifications interfere with the merge, again, it
-stops before touching anything.
-
-So in the above two "failed merge" case, you do not have to
-worry about loss of data --- you simply were not ready to do
-a merge, so no merge happened at all.  You may want to finish
-whatever you were in the middle of doing, and retry the same
-pull after you are done and ready.
-
-When things cleanly merge, these things happen:
-
-1. the results are updated both in the index file and in your
-   working tree,
-2. index file is written out as a tree,
-3. the tree gets committed, and 
-4. the `HEAD` pointer gets advanced.
-
-Because of 2., we require that the original state of the index
-file to match exactly the current `HEAD` commit; otherwise we
-will write out your local changes already registered in your
-index file along with the merge result, which is not good.
-Because 1. involves only the paths different between your
-branch and the remote branch you are pulling from during the
-merge (which is typically a fraction of the whole tree), you can
-have local modifications in your working tree as long as they do
-not overlap with what the merge updates.
-
-When there are conflicts, these things happen:
-
-1. `HEAD` stays the same.
-
-2. Cleanly merged paths are updated both in the index file and
-   in your working tree.
+In such a case, you can "unwrap" the tag yourself before feeding it
+to `git merge`, or pass `--ff-only` when you do not have any work on
+your own. e.g.
 
-3. For conflicting paths, the index file records up to three
-   versions; stage1 stores the version from the common ancestor,
-   stage2 from `HEAD`, and stage3 from the remote branch (you
-   can inspect the stages with `git-ls-files -u`).  The working
-   tree files have the result of "merge" program; i.e. 3-way
-   merge result with familiar conflict markers `<<< === >>>`.
+----
+git fetch origin
+git merge v1.2.3^0
+git merge --ff-only v1.2.3
+----
 
-4. No other changes are done.  In particular, the local
-   modifications you had before you started merge will stay the
-   same and the index entries for them stay as they were,
-   i.e. matching `HEAD`.
+
+HOW CONFLICTS ARE PRESENTED
+---------------------------
+
+During a merge, the working tree files are updated to reflect the result
+of the merge.  Among the changes made to the common ancestor's version,
+non-overlapping ones (that is, you changed an area of the file while the
+other side left that area intact, or vice versa) are incorporated in the
+final result verbatim.  When both sides made changes to the same area,
+however, Git cannot randomly pick one side over the other, and asks you to
+resolve it by leaving what both sides did to that area.
+
+By default, Git uses the same style as the one used by the "merge" program
+from the RCS suite to present such a conflicted hunk, like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+The area where a pair of conflicting changes happened is marked with markers
+`<<<<<<<`, `=======`, and `>>>>>>>`.  The part before the `=======`
+is typically your side, and the part afterwards is typically their side.
+
+The default format does not show what the original said in the conflicting
+area.  You cannot tell how many lines are deleted and replaced with
+Barbie's remark on your side.  The only thing you can tell is that your
+side wants to say it is hard and you'd prefer to go shopping, while the
+other side wants to claim it is easy.
+
+An alternative style can be used by setting the "merge.conflictStyle"
+configuration variable to "diff3".  In "diff3" style, the above conflict
+may look like this:
+
+------------
+Here are lines that are either unchanged from the common
+ancestor, or cleanly resolved because only one side changed.
+<<<<<<< yours:sample.txt
+Conflict resolution is hard;
+let's go shopping.
+|||||||
+Conflict resolution is hard.
+=======
+Git makes conflict resolution easy.
+>>>>>>> theirs:sample.txt
+And here is another line that is cleanly resolved or unmodified.
+------------
+
+In addition to the `<<<<<<<`, `=======`, and `>>>>>>>` markers, it uses
+another `|||||||` marker that is followed by the original text.  You can
+tell that the original just stated a fact, and your side simply gave in to
+that statement and gave up, while the other side tried to have a more
+positive attitude.  You can sometimes come up with a better resolution by
+viewing the original.
+
+
+HOW TO RESOLVE CONFLICTS
+------------------------
 
 After seeing a conflict, you can do two things:
 
- * Decide not to merge.  The only clean-up you need are to reset
+ * Decide not to merge.  The only clean-ups you need are to reset
    the index file to the `HEAD` commit to reverse 2. and to clean
-   up working tree changes made by 2. and 3.; `git-reset` can
-   be used for this.
+   up working tree changes made by 2. and 3.; `git merge --abort`
+   can be used for this.
 
- * Resolve the conflicts.  `git-diff` would report only the
-   conflicting paths because of the above 2. and 3..  Edit the
-   working tree files into a desirable shape, `git-add` or `git-rm`
-   them, to make the index file contain what the merge result
-   should be, and run `git-commit` to commit the result.
+ * Resolve the conflicts.  Git will mark the conflicts in
+   the working tree.  Edit the files into shape and
+   'git add' them to the index.  Use 'git commit' to seal the deal.
 
+You can work through the conflict with a number of tools:
 
-SEE ALSO
+ * Use a mergetool.  `git mergetool` to launch a graphical
+   mergetool which will work you through the merge.
+
+ * Look at the diffs.  `git diff` will show a three-way diff,
+   highlighting changes from both the `HEAD` and `MERGE_HEAD`
+   versions.
+
+ * Look at the diffs from each branch. `git log --merge -p <path>`
+   will show diffs first for the `HEAD` version and then the
+   `MERGE_HEAD` version.
+
+ * Look at the originals.  `git show :1:filename` shows the
+   common ancestor, `git show :2:filename` shows the `HEAD`
+   version, and `git show :3:filename` shows the `MERGE_HEAD`
+   version.
+
+
+EXAMPLES
 --------
-gitlink:git-fmt-merge-msg[1], gitlink:git-pull[1]
 
+* Merge branches `fixes` and `enhancements` on top of
+  the current branch, making an octopus merge:
++
+------------------------------------------------
+$ git merge fixes enhancements
+------------------------------------------------
+
+* Merge branch `obsolete` into the current branch, using `ours`
+  merge strategy:
++
+------------------------------------------------
+$ git merge -s ours obsolete
+------------------------------------------------
+
+* Merge branch `maint` into the current branch, but do not make
+  a new commit automatically:
++
+------------------------------------------------
+$ git merge --no-commit maint
+------------------------------------------------
++
+This can be used when you want to include further changes to the
+merge, or want to write your own merge commit message.
++
+You should refrain from abusing this option to sneak substantial
+changes into a merge commit.  Small fixups like bumping
+release/version name would be acceptable.

+git-mergetool(1)
+================
+
+NAME
+----
+git-mergetool - Run merge conflict resolution tools to resolve merge conflicts
+
+SYNOPSIS
+--------
+[verse]
+'git mergetool' [--tool=<tool>] [-y | --[no-]prompt] [<file>...]
+
+DESCRIPTION
+-----------
+
+Use `git mergetool` to run one of several merge utilities to resolve
+merge conflicts.  It is typically run after 'git merge'.
+
+If one or more <file> parameters are given, the merge tool program will
+be run to resolve differences on each file (skipping those without
+conflicts).  Specifying a directory will include all unresolved files in
+that path.  If no <file> names are specified, 'git mergetool' will run
+the merge tool program on every file with merge conflicts.
+
+OPTIONS
+-------
+-t <tool>::
+--tool=<tool>::
+	Use the merge resolution program specified by <tool>.
+	Valid values include emerge, gvimdiff, kdiff3,
+	meld, vimdiff, and tortoisemerge. Run `git mergetool --tool-help`
+	for the list of valid <tool> settings.
++
+If a merge resolution program is not specified, 'git mergetool'
+will use the configuration variable `merge.tool`.  If the
+configuration variable `merge.tool` is not set, 'git mergetool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `mergetool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`mergetool.kdiff3.path`. Otherwise, 'git mergetool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known merge tool programs,
+'git mergetool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `mergetool.<tool>.cmd`.
++
+When 'git mergetool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `merge.tool` configuration
+variable) the configured command line will be invoked with `$BASE`
+set to the name of a temporary file containing the common base for
+the merge, if available; `$LOCAL` set to the name of a temporary
+file containing the contents of the file on the current branch;
+`$REMOTE` set to the name of a temporary file containing the
+contents of the file to be merged, and `$MERGED` set to the name
+of the file to which the merge tool should write the result of the
+merge resolution.
++
+If the custom merge tool correctly indicates the success of a
+merge resolution with its exit code, then the configuration
+variable `mergetool.<tool>.trustExitCode` can be set to `true`.
+Otherwise, 'git mergetool' will prompt the user to indicate the
+success of the resolution after the custom tool has exited.
+
+--tool-help::
+	Print a list of merge tools that may be used with `--tool`.
+
+-y::
+--no-prompt::
+	Don't prompt before each invocation of the merge resolution
+	program.
+	This is the default if the merge resolution program is
+	explicitly specified with the `--tool` option or with the
+	`merge.tool` configuration variable.
+
+--prompt::
+	Prompt before each invocation of the merge resolution program
+	to give the user a chance to skip the path.
+
+TEMPORARY FILES
+---------------
+`git mergetool` creates `*.orig` backup files while resolving merges.
+These are safe to remove once a file has been merged and its
+`git mergetool` session has completed.
+
+Setting the `mergetool.keepBackup` configuration variable to `false`
+causes `git mergetool` to automatically remove the backup as files
+are successfully merged.

+checkout will remain in the old location and an empty directory will
+appear in the new location. To populate the submodule again in the new
+location the user will have to run "git submodule update"
+afterwards. Removing the old directory is only safe when it uses a
+gitfile, as otherwise the history of the submodule will be deleted
+too. Both steps will be obsolete when recursive submodule update has
+been implemented.

+DESCRIPTION
+-----------
+Adds, removes, or reads notes attached to objects, without touching
+the objects themselves.
+
+By default, notes are saved to and read from `refs/notes/commits`, but
+this default can be overridden.  See the OPTIONS, CONFIGURATION, and
+ENVIRONMENT sections below.  If this ref does not exist, it will be
+quietly created when it is first needed to store a note.
+
+A typical use of notes is to supplement a commit message without
+changing the commit itself. Notes can be shown by 'git log' along with
+the original commit message. To distinguish these notes from the
+message stored in the commit object, the notes are indented like the
+message, after an unindented line saying "Notes (<refname>):" (or
+"Notes:" for `refs/notes/commits`).
+
+Notes can also be added to patches prepared with `git format-patch` by
+using the `--notes` option. Such notes are added as a patch commentary
+after a three dash separator line.
+
+To change which notes are shown by 'git log', see the
+"notes.displayRef" configuration in linkgit:git-log[1].
+
+See the "notes.rewrite.<command>" configuration for a way to carry
+notes across commands that rewrite commits.

+	List the notes object for a given object. If no object is
+	given, show a list of all note objects and the objects they
+	annotate (in the format "<note object> <annotated object>").
+	This is the default subcommand if no subcommand is given.
+
+add::
+	Add notes for a given object (defaults to HEAD). Abort if the
+	object already has notes (use `-f` to overwrite existing notes).
+	However, if you're using `add` interactively (using an editor
+	to supply the notes contents), then - instead of aborting -
+	the existing notes will be opened in the editor (like the `edit`
+	subcommand).
+
+copy::
+	Copy the notes for the first object onto the second object.
+	Abort if the second object already has notes, or if the first
+	object has none (use -f to overwrite existing notes to the
+	second object). This subcommand is equivalent to:
+	`git notes add [-f] -C $(git notes list <from-object>) <to-object>`
++
+In `--stdin` mode, take lines in the format
++
+----------
+<from-object> SP <to-object> [ SP <rest> ] LF
+----------
++
+on standard input, and copy the notes from each <from-object> to its
+corresponding <to-object>.  (The optional `<rest>` is ignored so that
+the command can read the input given to the `post-rewrite` hook.)
+
+append::
+	Append to the notes of an existing object (defaults to HEAD).
+	Creates a new notes object if needed.
+
+edit::
+	Edit the notes for a given object (defaults to HEAD).
+
+show::
+	Show the notes for a given object (defaults to HEAD).
+
+merge::
+	Merge the given notes ref into the current notes ref.
+	This will try to merge the changes made by the given
+	notes ref (called "remote") since the merge-base (if
+	any) into the current notes ref (called "local").
++
+If conflicts arise and a strategy for automatically resolving
+conflicting notes (see the "NOTES MERGE STRATEGIES" section) is not given,
+the "manual" resolver is used. This resolver checks out the
+conflicting notes in a special worktree (`.git/NOTES_MERGE_WORKTREE`),
+and instructs the user to manually resolve the conflicts there.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+remove::
+	Remove the notes for given objects (defaults to HEAD). When
+	giving zero or one object from the command line, this is
+	equivalent to specifying an empty note message to
+	the `edit` subcommand.
+
+prune::
+	Remove all notes for non-existing/unreachable objects.
+
+get-ref::
+	Print the current notes ref. This provides an easy way to
+	retrieve the current notes ref (e.g. from scripts).
+
+OPTIONS
+-------
+-f::
+--force::
+	When adding notes to an object that already has notes,
+	overwrite the existing notes (instead of aborting).
+
+-m <msg>::
+--message=<msg>::
+	Use the given note message (instead of prompting).
+	If multiple `-m` options are given, their values
+	are concatenated as separate paragraphs.
+	Lines starting with `#` and empty lines other than a
+	single line between paragraphs will be stripped out.
+
+-F <file>::
+--file=<file>::
+	Take the note message from the given file.  Use '-' to
+	read the note message from the standard input.
+	Lines starting with `#` and empty lines other than a
+	single line between paragraphs will be stripped out.
+
+-C <object>::
+--reuse-message=<object>::
+	Take the given blob object (for	example, another note) as the
+	note message. (Use `git notes copy <object>` instead to
+	copy notes between objects.)
+
+-c <object>::
+--reedit-message=<object>::
+	Like '-C', but with '-c' the editor is invoked, so that
+	the user can further edit the note message.
+
+--allow-empty::
+	Allow an empty note object to be stored. The default behavior is
+	to automatically remove empty notes.
+
+--ref <ref>::
+	Manipulate the notes tree in <ref>.  This overrides
+	'GIT_NOTES_REF' and the "core.notesRef" configuration.  The ref
+	is taken to be in `refs/notes/` if it is not qualified.
+
+--ignore-missing::
+	Do not consider it an error to request removing notes from an
+	object that does not have notes attached to it.
+
+--stdin::
+	Also read the object names to remove notes from from the standard
+	input (there is no reason you cannot combine this with object
+	names from the command line).
+
+-n::
+--dry-run::
+	Do not remove anything; just report the object names whose notes
+	would be removed.
+
+-s <strategy>::
+--strategy=<strategy>::
+	When merging notes, resolve notes conflicts using the given
+	strategy. The following strategies are recognized: "manual"
+	(default), "ours", "theirs", "union" and "cat_sort_uniq".
+	This option overrides the "notes.mergeStrategy" configuration setting.
+	See the "NOTES MERGE STRATEGIES" section below for more
+	information on each notes merge strategy.
+
+--commit::
+	Finalize an in-progress 'git notes merge'. Use this option
+	when you have resolved the conflicts that 'git notes merge'
+	stored in .git/NOTES_MERGE_WORKTREE. This amends the partial
+	merge commit created by 'git notes merge' (stored in
+	.git/NOTES_MERGE_PARTIAL) by adding the notes in
+	.git/NOTES_MERGE_WORKTREE. The notes ref stored in the
+	.git/NOTES_MERGE_REF symref is updated to the resulting commit.
+
+--abort::
+	Abort/reset a in-progress 'git notes merge', i.e. a notes merge
+	with conflicts. This simply removes all files related to the
+	notes merge.
+
+-q::
+--quiet::
+	When merging notes, operate quietly.
+
+-v::
+--verbose::
+	When merging notes, be more verbose.
+	When pruning notes, report all object names whose notes are
+	removed.
+
+
+DISCUSSION
+----------
+
+Commit notes are blobs containing extra information about an object
+(usually information to supplement a commit's message).  These blobs
+are taken from notes refs.  A notes ref is usually a branch which
+contains "files" whose paths are the object names for the objects
+they describe, with some directory separators included for performance
+reasons footnote:[Permitted pathnames have the form
+'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
+names of two hexadecimal digits each followed by a filename with the
+rest of the object ID.].
+
+Every notes change creates a new commit at the specified notes ref.
+You can therefore inspect the history of the notes by invoking, e.g.,
+`git log -p notes/commits`.  Currently the commit message only records
+which operation triggered the update, and the commit authorship is
+determined according to the usual rules (see linkgit:git-commit[1]).
+These details may change in the future.
+
+It is also permitted for a notes ref to point directly to a tree
+object, in which case the history of the notes can be read with
+`git log -p -g <refname>`.
+
+
+NOTES MERGE STRATEGIES
+----------------------
+
+The default notes merge strategy is "manual", which checks out
+conflicting notes in a special work tree for resolving notes conflicts
+(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
+conflicts in that work tree.
+When done, the user can either finalize the merge with
+'git notes merge --commit', or abort the merge with
+'git notes merge --abort'.
+
+Users may select an automated merge strategy from among the following using
+either -s/--strategy option or configuring notes.mergeStrategy accordingly:
+
+"ours" automatically resolves conflicting notes in favor of the local
+version (i.e. the current notes ref).
+
+"theirs" automatically resolves notes conflicts in favor of the remote
+version (i.e. the given notes ref being merged into the current notes
+ref).
+
+"union" automatically resolves notes conflicts by concatenating the
+local and remote versions.
+
+"cat_sort_uniq" is similar to "union", but in addition to concatenating
+the local and remote versions, this strategy also sorts the resulting
+lines, and removes duplicate lines from the result. This is equivalent
+to applying the "cat | sort | uniq" shell pipeline to the local and
+remote versions. This strategy is useful if the notes follow a line-based
+format where one wants to avoid duplicated lines in the merge result.
+Note that if either the local or remote version contain duplicate lines
+prior to the merge, these will also be removed by this notes merge
+strategy.
+
+
+EXAMPLES
+--------
+
+You can use notes to add annotations with information that was not
+available at the time a commit was written.
+
+------------
+$ git notes add -m 'Tested-by: Johannes Sixt <j6t@kdbg.org>' 72a144e2
+$ git show -s 72a144e
+[...]

+
+Notes:
+    Tested-by: Johannes Sixt <j6t@kdbg.org>
+------------
+
+In principle, a note is a regular Git blob, and any kind of
+(non-)format is accepted.  You can binary-safely create notes from
+arbitrary files using 'git hash-object':
+
+------------
+$ cc *.c
+$ blob=$(git hash-object -w a.out)
+$ git notes --ref=built add --allow-empty -C "$blob" HEAD
+------------
+
+(You cannot simply use `git notes --ref=built add -F a.out HEAD`
+because that is not binary-safe.)
+Of course, it doesn't make much sense to display non-text-format notes
+with 'git log', so if you use such notes, you'll probably need to write
+some special-purpose tools to do something useful with them.
+
+
+CONFIGURATION
+-------------
+
+core.notesRef::
+	Notes ref to read and manipulate instead of
+	`refs/notes/commits`.  Must be an unabbreviated ref name.
+	This setting can be overridden through the environment and
+	command line.
+
+notes.mergeStrategy::
+	Which merge strategy to choose by default when resolving notes
+	conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
+	`cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
+	section above for more information on each strategy.
++
+This setting can be overridden by passing the `--strategy` option.
+
+notes.<name>.mergeStrategy::
+	Which merge strategy to choose when doing a notes merge into
+	refs/notes/<name>.  This overrides the more general
+	"notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section above
+	for more information on each available strategy.
+
+notes.displayRef::
+	Which ref (or refs, if a glob or specified more than once), in
+	addition to the default set by `core.notesRef` or
+	'GIT_NOTES_REF', to read notes from when showing commit
+	messages with the 'git log' family of commands.
+	This setting can be overridden on the command line or by the
+	'GIT_NOTES_DISPLAY_REF' environment variable.
+	See linkgit:git-log[1].
+
+notes.rewrite.<command>::
+	When rewriting commits with <command> (currently `amend` or
+	`rebase`), if this variable is `false`, git will not copy
+	notes from the original to the rewritten commit.  Defaults to
+	`true`.  See also "`notes.rewriteRef`" below.
++
+This setting can be overridden by the 'GIT_NOTES_REWRITE_REF'
+environment variable.
+
+notes.rewriteMode::
+	When copying notes during a rewrite, what to do if the target
+	commit already has a note.  Must be one of `overwrite`,
+	`concatenate`, `cat_sort_uniq`, or `ignore`.  Defaults to
+	`concatenate`.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
+environment variable.
+
+notes.rewriteRef::
+	When copying notes during a rewrite, specifies the (fully
+	qualified) ref whose notes should be copied.  May be a glob,
+	in which case notes in all matching refs will be copied.  You
+	may also specify this configuration several times.
++
+Does not have a default value; you must configure this variable to
+enable note rewriting.
++
+Can be overridden with the 'GIT_NOTES_REWRITE_REF' environment variable.
+
+
+ENVIRONMENT
+-----------
+
+'GIT_NOTES_REF'::
+	Which ref to manipulate notes from, instead of `refs/notes/commits`.
+	This overrides the `core.notesRef` setting.
+
+'GIT_NOTES_DISPLAY_REF'::
+	Colon-delimited list of refs or globs indicating which refs,
+	in addition to the default from `core.notesRef` or
+	'GIT_NOTES_REF', to read notes from when showing commit
+	messages.
+	This overrides the `notes.displayRef` setting.
++
+A warning will be issued for refs that do not exist, but a glob that
+does not match any refs is silently ignored.
+
+'GIT_NOTES_REWRITE_MODE'::
+	When copying notes during a rewrite, what to do if the target
+	commit already has a note.
+	Must be one of `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
+	This overrides the `core.rewriteMode` setting.
+
+'GIT_NOTES_REWRITE_REF'::
+	When rewriting commits, which notes to copy from the original
+	to the rewritten commit.  Must be a colon-delimited list of
+	refs or globs.
++
+If not set in the environment, the list of notes to copy depends
+on the `notes.rewrite.<command>` and `notes.rewriteRef` settings.

+NAME

+git-p4 - Import from and submit to Perforce repositories
+
+
+SYNOPSIS
+--------
+[verse]
+'git p4 clone' [<sync options>] [<clone options>] <p4 depot path>...
+'git p4 sync' [<sync options>] [<p4 depot path>...]
+'git p4 rebase'
+'git p4 submit' [<submit options>] [<master branch name>]
+
+
+DESCRIPTION
+-----------
+This command provides a way to interact with p4 repositories
+using Git.
+
+Create a new Git repository from an existing p4 repository using
+'git p4 clone', giving it one or more p4 depot paths.  Incorporate
+new commits from p4 changes with 'git p4 sync'.  The 'sync' command
+is also used to include new branches from other p4 depot paths.
+Submit Git changes back to p4 using 'git p4 submit'.  The command
+'git p4 rebase' does a sync plus rebases the current branch onto
+the updated p4 remote branch.
+
+
+EXAMPLE
+-------
+* Clone a repository:
++
+------------
+$ git p4 clone //depot/path/project
+------------
+
+* Do some work in the newly created Git repository:
++
+------------
+$ cd project
+$ vi foo.h
+$ git commit -a -m "edited foo.h"
+------------
+
+* Update the Git repository with recent changes from p4, rebasing your
+  work on top:
++
+------------
+$ git p4 rebase
+------------
+
+* Submit your commits back to p4:
++
+------------
+$ git p4 submit
+------------
+
+
+COMMANDS
+--------
+
+Clone
+~~~~~
+Generally, 'git p4 clone' is used to create a new Git directory
+from an existing p4 repository:
+------------
+$ git p4 clone //depot/path/project
+------------
+This:
+
+1.   Creates an empty Git repository in a subdirectory called 'project'.
++
+2.   Imports the full contents of the head revision from the given p4
+depot path into a single commit in the Git branch 'refs/remotes/p4/master'.
++
+3.   Creates a local branch, 'master' from this remote and checks it out.
+
+To reproduce the entire p4 history in Git, use the '@all' modifier on
+the depot path:
+------------
+$ git p4 clone //depot/path/project@all
+------------
+
+
+Sync
+~~~~
+As development continues in the p4 repository, those changes can
+be included in the Git repository using:
+------------
+$ git p4 sync
+------------
+This command finds new changes in p4 and imports them as Git commits.
+
+P4 repositories can be added to an existing Git repository using
+'git p4 sync' too:
+------------
+$ mkdir repo-git
+$ cd repo-git
+$ git init
+$ git p4 sync //path/in/your/perforce/depot
+------------
+This imports the specified depot into
+'refs/remotes/p4/master' in an existing Git repository.  The
+'--branch' option can be used to specify a different branch to
+be used for the p4 content.
+
+If a Git repository includes branches 'refs/remotes/origin/p4', these
+will be fetched and consulted first during a 'git p4 sync'.  Since
+importing directly from p4 is considerably slower than pulling changes
+from a Git remote, this can be useful in a multi-developer environment.
+
+If there are multiple branches, doing 'git p4 sync' will automatically
+use the "BRANCH DETECTION" algorithm to try to partition new changes
+into the right branch.  This can be overridden with the '--branch'
+option to specify just a single branch to update.
+
+
+Rebase
+~~~~~~
+A common working pattern is to fetch the latest changes from the p4 depot
+and merge them with local uncommitted changes.  Often, the p4 repository
+is the ultimate location for all code, thus a rebase workflow makes
+sense.  This command does 'git p4 sync' followed by 'git rebase' to move
+local commits on top of updated p4 changes.
+------------
+$ git p4 rebase
+------------
+
+
+Submit
+~~~~~~
+Submitting changes from a Git repository back to the p4 repository
+requires a separate p4 client workspace.  This should be specified
+using the 'P4CLIENT' environment variable or the Git configuration
+variable 'git-p4.client'.  The p4 client must exist, but the client root
+will be created and populated if it does not already exist.
+
+To submit all changes that are in the current Git branch but not in
+the 'p4/master' branch, use:
+------------
+$ git p4 submit
+------------
+
+To specify a branch other than the current one, use:
+------------
+$ git p4 submit topicbranch
+------------
+
+The upstream reference is generally 'refs/remotes/p4/master', but can
+be overridden using the '--origin=' command-line option.
+
+The p4 changes will be created as the user invoking 'git p4 submit'. The
+'--preserve-user' option will cause ownership to be modified
+according to the author of the Git commit.  This option requires admin
+privileges in p4, which can be granted using 'p4 protect'.
+
+
+OPTIONS
+-------
+
+General options
+~~~~~~~~~~~~~~~
+All commands except clone accept these options.
+
+--git-dir <dir>::
+	Set the 'GIT_DIR' environment variable.  See linkgit:git[1].
+
+-v::
+--verbose::
+	Provide more progress information.
+
+Sync options
+~~~~~~~~~~~~
+These options can be used in the initial 'clone' as well as in
+subsequent 'sync' operations.
+
+--branch <ref>::
+	Import changes into <ref> instead of refs/remotes/p4/master.
+	If <ref> starts with refs/, it is used as is.  Otherwise, if
+	it does not start with p4/, that prefix is added.
++
+By default a <ref> not starting with refs/ is treated as the
+name of a remote-tracking branch (under refs/remotes/).  This
+behavior can be modified using the --import-local option.
++
+The default <ref> is "master".
++
+This example imports a new remote "p4/proj2" into an existing
+Git repository:
++
+----
+    $ git init
+    $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
+----
+
+--detect-branches::
+	Use the branch detection algorithm to find new paths in p4.  It is
+	documented below in "BRANCH DETECTION".
+
+--changesfile <file>::
+	Import exactly the p4 change numbers listed in 'file', one per
+	line.  Normally, 'git p4' inspects the current p4 repository
+	state and detects the changes it should import.
+
+--silent::
+	Do not print any progress information.
+
+--detect-labels::
+	Query p4 for labels associated with the depot paths, and add
+	them as tags in Git. Limited usefulness as only imports labels
+	associated with new changelists. Deprecated.
+
+--import-labels::
+	Import labels from p4 into Git.
+
+--import-local::
+	By default, p4 branches are stored in 'refs/remotes/p4/',
+	where they will be treated as remote-tracking branches by
+	linkgit:git-branch[1] and other commands.  This option instead
+	puts p4 branches in 'refs/heads/p4/'.  Note that future
+	sync operations must specify '--import-local' as well so that
+	they can find the p4 branches in refs/heads.
+
+--max-changes <n>::
+	Import at most 'n' changes, rather than the entire range of
+	changes included in the given revision specifier. A typical
+	usage would be use '@all' as the revision specifier, but then
+	to use '--max-changes 1000' to import only the last 1000
+	revisions rather than the entire revision history.
+
+--changes-block-size <n>::
+	The internal block size to use when converting a revision
+	specifier such as '@all' into a list of specific change
+	numbers. Instead of using a single call to 'p4 changes' to
+	find the full list of changes for the conversion, there are a
+	sequence of calls to 'p4 changes -m', each of which requests
+	one block of changes of the given size. The default block size
+	is 500, which should usually be suitable.
+
+--keep-path::
+	The mapping of file names from the p4 depot path to Git, by
+	default, involves removing the entire depot path.  With this
+	option, the full p4 depot path is retained in Git.  For example,
+	path '//depot/main/foo/bar.c', when imported from
+	'//depot/main/', becomes 'foo/bar.c'.  With '--keep-path', the
+	Git path is instead 'depot/main/foo/bar.c'.
+
+--use-client-spec::
+	Use a client spec to find the list of interesting files in p4.
+	See the "CLIENT SPEC" section below.
+
+-/ <path>::
+	Exclude selected depot paths when cloning or syncing.
+
+Clone options
+~~~~~~~~~~~~~
+These options can be used in an initial 'clone', along with the 'sync'
+options described above.
+
+--destination <directory>::
+	Where to create the Git repository.  If not provided, the last
+	component in the p4 depot path is used to create a new
+	directory.
+
+--bare::
+	Perform a bare clone.  See linkgit:git-clone[1].
+
+Submit options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 submit' behavior.
+
+--origin <commit>::
+	Upstream location from which commits are identified to submit to
+	p4.  By default, this is the most recent p4 commit reachable
+	from 'HEAD'.
+
+-M::
+	Detect renames.  See linkgit:git-diff[1].  Renames will be
+	represented in p4 using explicit 'move' operations.  There
+	is no corresponding option to detect copies, but there are
+	variables for both moves and copies.
+
+--preserve-user::
+	Re-author p4 changes before submitting to p4.  This option
+	requires p4 admin privileges.
+
+--export-labels::
+	Export tags from Git as p4 labels. Tags found in Git are applied
+	to the perforce working directory.
+
+-n::
+--dry-run::
+	Show just what commits would be submitted to p4; do not change
+	state in Git or p4.
+
+--prepare-p4-only::
+	Apply a commit to the p4 workspace, opening, adding and deleting
+	files in p4 as for a normal submit operation.  Do not issue the
+	final "p4 submit", but instead print a message about how to
+	submit manually or revert.  This option always stops after the
+	first (oldest) commit.  Git tags are not exported to p4.
+
+--conflict=(ask|skip|quit)::
+	Conflicts can occur when applying a commit to p4.  When this
+	happens, the default behavior ("ask") is to prompt whether to
+	skip this commit and continue, or quit.  This option can be used
+	to bypass the prompt, causing conflicting commits to be automatically
+	skipped, or to quit trying to apply commits, without prompting.
+
+--branch <branch>::
+	After submitting, sync this named branch instead of the default
+	p4/master.  See the "Sync options" section above for more
+	information.
+
+Rebase options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 rebase' behavior.
+
+--import-labels::
+	Import p4 labels.
+
+DEPOT PATH SYNTAX
+-----------------
+The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
+be one or more space-separated p4 depot paths, with an optional
+p4 revision specifier on the end:
+
+"//depot/my/project"::
+    Import one commit with all files in the '#head' change under that tree.
+
+"//depot/my/project@all"::
+    Import one commit for each change in the history of that depot path.
+
+"//depot/my/project@1,6"::
+    Import only changes 1 through 6.
+
+"//depot/proj1@all //depot/proj2@all"::
+    Import all changes from both named depot paths into a single
+    repository.  Only files below these directories are included.
+    There is not a subdirectory in Git for each "proj1" and "proj2".
+    You must use the '--destination' option when specifying more
+    than one depot path.  The revision specifier must be specified
+    identically on each depot path.  If there are files in the
+    depot paths with the same name, the path with the most recently
+    updated version of the file is the one that appears in Git.
+
+See 'p4 help revisions' for the full syntax of p4 revision specifiers.
+
+
+CLIENT SPEC
+-----------
+The p4 client specification is maintained with the 'p4 client' command
+and contains among other fields, a View that specifies how the depot
+is mapped into the client repository.  The 'clone' and 'sync' commands
+can consult the client spec when given the '--use-client-spec' option or
+when the useClientSpec variable is true.  After 'git p4 clone', the
+useClientSpec variable is automatically set in the repository
+configuration file.  This allows future 'git p4 submit' commands to
+work properly; the submit command looks only at the variable and does
+not have a command-line option.
+
+The full syntax for a p4 view is documented in 'p4 help views'.  'git p4'
+knows only a subset of the view syntax.  It understands multi-line
+mappings, overlays with '+', exclusions with '-' and double-quotes
+around whitespace.  Of the possible wildcards, 'git p4' only handles
+'...', and only when it is at the end of the path.  'git p4' will complain
+if it encounters an unhandled wildcard.
+
+Bugs in the implementation of overlap mappings exist.  If multiple depot
+paths map through overlays to the same location in the repository,
+'git p4' can choose the wrong one.  This is hard to solve without
+dedicating a client spec just for 'git p4'.
+
+The name of the client can be given to 'git p4' in multiple ways.  The
+variable 'git-p4.client' takes precedence if it exists.  Otherwise,
+normal p4 mechanisms of determining the client are used:  environment
+variable P4CLIENT, a file referenced by P4CONFIG, or the local host name.
+
+
+BRANCH DETECTION
+----------------
+P4 does not have the same concept of a branch as Git.  Instead,
+p4 organizes its content as a directory tree, where by convention
+different logical branches are in different locations in the tree.
+The 'p4 branch' command is used to maintain mappings between
+different areas in the tree, and indicate related content.  'git p4'
+can use these mappings to determine branch relationships.
+
+If you have a repository where all the branches of interest exist as
+subdirectories of a single depot path, you can use '--detect-branches'
+when cloning or syncing to have 'git p4' automatically find
+subdirectories in p4, and to generate these as branches in Git.
+
+For example, if the P4 repository structure is:
+----
+//depot/main/...
+//depot/branch1/...
+----
+
+And "p4 branch -o branch1" shows a View line that looks like:
+----
+//depot/main/... //depot/branch1/...
+----
+
+Then this 'git p4 clone' command:
+----
+git p4 clone --detect-branches //depot@all
+----
+produces a separate branch in 'refs/remotes/p4/' for //depot/main,
+called 'master', and one for //depot/branch1 called 'depot/branch1'.
+
+However, it is not necessary to create branches in p4 to be able to use
+them like branches.  Because it is difficult to infer branch
+relationships automatically, a Git configuration setting
+'git-p4.branchList' can be used to explicitly identify branch
+relationships.  It is a list of "source:destination" pairs, like a
+simple p4 branch specification, where the "source" and "destination" are
+the path elements in the p4 repository.  The example above relied on the
+presence of the p4 branch.  Without p4 branches, the same result will
+occur with:
+----
+git init depot
+cd depot
+git config git-p4.branchList main:branch1
+git p4 clone --detect-branches //depot@all .
+----
+
+
+PERFORMANCE
+-----------
+The fast-import mechanism used by 'git p4' creates one pack file for
+each invocation of 'git p4 sync'.  Normally, Git garbage compression
+(linkgit:git-gc[1]) automatically compresses these to fewer pack files,
+but explicit invocation of 'git repack -adf' may improve performance.
+
+
+CONFIGURATION VARIABLES
+-----------------------
+The following config settings can be used to modify 'git p4' behavior.
+They all are in the 'git-p4' section.
+
+General variables
+~~~~~~~~~~~~~~~~~
+git-p4.user::
+	User specified as an option to all p4 commands, with '-u <user>'.
+	The environment variable 'P4USER' can be used instead.
+
+git-p4.password::
+	Password specified as an option to all p4 commands, with
+	'-P <password>'.
+	The environment variable 'P4PASS' can be used instead.
+
+git-p4.port::
+	Port specified as an option to all p4 commands, with
+	'-p <port>'.
+	The environment variable 'P4PORT' can be used instead.
+
+git-p4.host::
+	Host specified as an option to all p4 commands, with
+	'-h <host>'.
+	The environment variable 'P4HOST' can be used instead.
+
+git-p4.client::
+	Client specified as an option to all p4 commands, with
+	'-c <client>', including the client spec.
+
+Clone and sync variables
+~~~~~~~~~~~~~~~~~~~~~~~~
+git-p4.syncFromOrigin::
+	Because importing commits from other Git repositories is much faster
+	than importing them from p4, a mechanism exists to find p4 changes
+	first in Git remotes.  If branches exist under 'refs/remote/origin/p4',
+	those will be fetched and used when syncing from p4.  This
+	variable can be set to 'false' to disable this behavior.
+
+git-p4.branchUser::
+	One phase in branch detection involves looking at p4 branches
+	to find new ones to import.  By default, all branches are
+	inspected.  This option limits the search to just those owned
+	by the single user named in the variable.
+
+git-p4.branchList::
+	List of branches to be imported when branch detection is
+	enabled.  Each entry should be a pair of branch names separated
+	by a colon (:).  This example declares that both branchA and
+	branchB were created from main:
++
+-------------
+git config       git-p4.branchList main:branchA
+git config --add git-p4.branchList main:branchB
+-------------
+
+git-p4.ignoredP4Labels::
+	List of p4 labels to ignore. This is built automatically as
+	unimportable labels are discovered.
+
+git-p4.importLabels::
+	Import p4 labels into git, as per --import-labels.
+
+git-p4.labelImportRegexp::
+	Only p4 labels matching this regular expression will be imported. The
+	default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.useClientSpec::
+	Specify that the p4 client spec should be used to identify p4
+	depot paths of interest.  This is equivalent to specifying the
+	option '--use-client-spec'.  See the "CLIENT SPEC" section above.
+	This variable is a boolean, not the name of a p4 client.
+
+Submit variables
+~~~~~~~~~~~~~~~~
+git-p4.detectRenames::
+	Detect renames.  See linkgit:git-diff[1].  This can be true,
+	false, or a score as expected by 'git diff -M'.
+
+git-p4.detectCopies::
+	Detect copies.  See linkgit:git-diff[1].  This can be true,
+	false, or a score as expected by 'git diff -C'.
+
+git-p4.detectCopiesHarder::
+	Detect copies harder.  See linkgit:git-diff[1].  A boolean.
+
+git-p4.preserveUser::
+	On submit, re-author changes to reflect the Git author,
+	regardless of who invokes 'git p4 submit'.
+
+git-p4.allowMissingP4Users::
+	When 'preserveUser' is true, 'git p4' normally dies if it
+	cannot find an author in the p4 user map.  This setting
+	submits the change regardless.
+
+git-p4.skipSubmitEdit::
+	The submit process invokes the editor before each p4 change
+	is submitted.  If this setting is true, though, the editing
+	step is skipped.
+
+git-p4.skipSubmitEditCheck::
+	After editing the p4 change message, 'git p4' makes sure that
+	the description really was changed by looking at the file
+	modification time.  This option disables that test.
+
+git-p4.allowSubmit::
+	By default, any branch can be used as the source for a 'git p4
+	submit' operation.  This configuration variable, if set, permits only
+	the named branches to be used as submit sources.  Branch names
+	must be the short names (no "refs/heads/"), and should be
+	separated by commas (","), with no spaces.
+
+git-p4.skipUserNameCheck::
+	If the user running 'git p4 submit' does not exist in the p4
+	user map, 'git p4' exits.  This option can be used to force
+	submission regardless.
+
+git-p4.attemptRCSCleanup::
+	If enabled, 'git p4 submit' will attempt to cleanup RCS keywords
+	($Header$, etc). These would otherwise cause merge conflicts and prevent
+	the submit going ahead. This option should be considered experimental at
+	present.
+
+git-p4.exportLabels::
+	Export Git tags to p4 labels, as per --export-labels.
+
+git-p4.labelExportRegexp::
+	Only p4 labels matching this regular expression will be exported. The
+	default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.conflict::
+	Specify submit behavior when a conflict with p4 is found, as per
+	--conflict.  The default behavior is 'ask'.
+
+IMPLEMENTATION DETAILS
+----------------------
+* Changesets from p4 are imported using Git fast-import.
+* Cloning or syncing does not require a p4 client; file contents are
+  collected using 'p4 print'.
+* Submitting requires a p4 client, which is not in the same location
+  as the Git repository.  Patches are applied, one at a time, to
+  this p4 client and submitted from there.
+* Each commit imported by 'git p4' has a line at the end of the log
+  message indicating the p4 depot location and change number.  This
+  line is used by later 'git p4 sync' operations to know which p4
+  changes are new.

-git-p4import - Import a Perforce repository into git
-
-
-SYNOPSIS
---------
-`git-p4import` [-q|-v] [--notags] [--authors <file>] [-t <timezone>] <//p4repo/path> <branch>
-
-`git-p4import` --stitch <//p4repo/path>
-
-`git-p4import`
-
-
-DESCRIPTION
------------
-Import a Perforce repository into an existing git repository.  When
-a <//p4repo/path> and <branch> are specified a new branch with the
-given name will be created and the initial import will begin.
-
-Once the initial import is complete you can do an incremental import
-of new commits from the Perforce repository.  You do this by checking
-out the appropriate git branch and then running `git-p4import` without
-any options.
-
-The standard p4 client is used to communicate with the Perforce
-repository; it must be configured correctly in order for `git-p4import`
-to operate (see below).
-
-
-OPTIONS
--------
--q::
-	Do not display any progress information.
-
--v::
-        Give extra progress information.
-
-\--authors::
-	Specify an authors file containing a mapping of Perforce user
-	ids to full names and email addresses (see Notes below).
-
-\--notags::
-	Do not create a tag for each imported commit.
-
-\--stitch::
-	Import the contents of the given perforce branch into the
-	currently checked out git branch.
-
-\--log::
-	Store debugging information in the specified file.
-
--t::
-	Specify that the remote repository is in the specified timezone.
-	Timezone must be in the format "US/Pacific" or "Europe/London"
-	etc.  You only need to specify this once, it will be saved in
-	the git config file for the repository.
-
-<//p4repo/path>::
-	The Perforce path that will be imported into the specified branch.
-
-<branch>::
-	The new branch that will be created to hold the Perforce imports.
-
-
-P4 Client
----------
-You must make the `p4` client command available in your $PATH and
-configure it to communicate with the target Perforce repository.
-Typically this means you must set the "$P4PORT" and "$P4CLIENT"
-environment variables.
-
-You must also configure a `p4` client "view" which maps the Perforce
-branch into the top level of your git repository, for example:
-
-------------
-Client: myhost
-
-Root:   /home/sean/import
-
-Options:   noallwrite clobber nocompress unlocked modtime rmdir
-
-View:
-        //public/jam/... //myhost/jam/...
-------------
-
-With the above `p4` client setup, you could import the "jam"
-perforce branch into a branch named "jammy", like so:
-
-------------
-$ mkdir -p /home/sean/import/jam
-$ cd /home/sean/import/jam
-$ git init
-$ git p4import //public/jam jammy
-------------
-
-
-Multiple Branches
------------------
-Note that by creating multiple "views" you can use `git-p4import`
-to import additional branches into the same git repository.
-However, the `p4` client has a limitation in that it silently
-ignores all but the last "view" that maps into the same local
-directory.  So the following will *not* work:
-
-------------
-View:
-        //public/jam/... //myhost/jam/...
-        //public/other/... //myhost/jam/...
-        //public/guest/... //myhost/jam/...
-------------
-
-If you want more than one Perforce branch to be imported into the
-same directory you must employ a workaround.  A simple option is
-to adjust your `p4` client before each import to only include a
-single view.
-
-Another option is to create multiple symlinks locally which all
-point to the same directory in your git repository and then use
-one per "view" instead of listing the actual directory.
-
-
-Tags
-----
-A git tag of the form p4/xx is created for every change imported from
-the Perforce repository where xx is the Perforce changeset number.
-Therefore after the import you can use git to access any commit by its
-Perforce number, e.g. git show p4/327.
-
-The tag associated with the HEAD commit is also how `git-p4import`
-determines if there are new changes to incrementally import from the
-Perforce repository.
-
-If you import from a repository with many thousands of changes
-you will have an equal number of p4/xxxx git tags.  Git tags can
-be expensive in terms of disk space and repository operations.
-If you don't need to perform further incremental imports, you
-may delete the tags.
-
-
-Notes
------
-You can interrupt the import (e.g. ctrl-c) at any time and restart it
-without worry.
-
-Author information is automatically determined by querying the
-Perforce "users" table using the id associated with each change.
-However, if you want to manually supply these mappings you can do
-so with the "--authors" option.  It accepts a file containing a list
-of mappings with each line containing one mapping in the format:
-

-    perforce_id = Full Name <email@address.com>

 DESCRIPTION
@@ -19,26 +21,28 @@ DESCRIPTION
 Reads list of objects from the standard input, and writes a packed
 archive with specified base-name, or to the standard output.
 
-A packed archive is an efficient way to transfer set of objects
-between two repositories, and also is an archival format which
-is efficient to access.  The packed archive format (.pack) is
-designed to be unpackable without having anything else, but for
-random access, accompanied with the pack index file (.idx).
+A packed archive is an efficient way to transfer a set of objects
+between two repositories as well as an access efficient archival
+format.  In a packed archive, an object is either stored as a
+compressed whole or as a difference from some other object.
+The latter is often called a delta.
 
-'git-unpack-objects' command can read the packed archive and
+The packed archive format (.pack) is designed to be self-contained
+so that it can be unpacked without any further information. Therefore,
+each object that a delta depends upon must be present within the pack.
+
+A pack index file (.idx) is generated for fast, random access to the
+objects in the pack. Placing both the index file (.idx) and the packed
+archive (.pack) in the pack/ subdirectory of $GIT_OBJECT_DIRECTORY (or
+any of the directories on $GIT_ALTERNATE_OBJECT_DIRECTORIES)
+enables Git to read from the pack archive.
+
+The 'git unpack-objects' command can read the packed archive and
 expand the objects contained in the pack into "one-file
 one-object" format; this is typically done by the smart-pull
 commands when a pack is created on-the-fly for efficient network
 transport by their peers.
 
-Placing both in the pack/ subdirectory of $GIT_OBJECT_DIRECTORY (or

-In a packed archive, an object is either stored as a compressed

 SYNOPSIS
 --------
-'git-pull' <options> <repository> <refspec>...
+[verse]
+'git pull' [options] [<repository> [<refspec>...]]
 
 
 DESCRIPTION
 -----------
-Runs `git-fetch` with the given parameters, and calls `git-merge`
-to merge the retrieved head(s) into the current branch.
 
-Note that you can use `.` (current directory) as the
-<repository> to pull from the local repository -- this is useful
-when merging local branches into the current branch.
+Incorporates changes from a remote repository into the current
+branch.  In its default mode, `git pull` is shorthand for
+`git fetch` followed by `git merge FETCH_HEAD`.
 
+More precisely, 'git pull' runs 'git fetch' with the given
+parameters and calls 'git merge' to merge the retrieved branch
+heads into the current branch.
+With `--rebase`, it runs 'git rebase' instead of 'git merge'.
+
+<repository> should be the name of a remote repository as
+passed to linkgit:git-fetch[1].  <refspec> can name an
+arbitrary remote ref (for example, the name of a tag) or even
+a collection of refs with corresponding remote-tracking branches
+(e.g., refs/heads/{asterisk}:refs/remotes/origin/{asterisk}),
+but usually it is the name of a branch in the remote repository.
+
+Default values for <repository> and <branch> are read from the
+"remote" and "merge" configuration for the current branch
+as set by linkgit:git-branch[1] `--track`.
+
+Assume the following history exists and the current branch is
+"`master`":
+
+------------
+	  A---B---C master on origin
+	 /
+    D---E---F---G master
+	^
+	origin/master in your repository
+------------
+
+Then "`git pull`" will fetch and replay the changes from the remote
+`master` branch since it diverged from the local `master` (i.e., `E`)
+until its current commit (`C`) on top of `master` and record the
+result in a new commit along with the names of the two parent commits
+and a log message from the user describing the changes.
+
+------------
+	  A---B---C origin/master
+	 /         \
+    D---E---F---G---H master
+------------
+
+See linkgit:git-merge[1] for details, including how conflicts
+are presented and handled.
+
+In Git 1.7.0 or later, to cancel a conflicting merge, use
+`git reset --merge`.  *Warning*: In older versions of Git, running 'git pull'
+with uncommitted changes is discouraged: while possible, it leaves you
+in a state that may be hard to back out of in the case of a conflict.
+
+If any of the remote changes overlap with local uncommitted changes,
+the merge will be automatically cancelled and the work tree untouched.
+It is generally best to get any local changes in working order before
+pulling or stash them away with linkgit:git-stash[1].

 DESCRIPTION

 You can make interesting things happen to a repository
 every time you push into it, by setting up 'hooks' there.  See
-documentation for gitlink:git-receive-pack[1].
+documentation for linkgit:git-receive-pack[1].
 
+When the command line does not specify where to push with the
+`<repository>` argument, `branch.*.remote` configuration for the
+current branch is consulted to determine where to push.  If the
+configuration is missing, it defaults to 'origin'.
 
-OPTIONS
--------
+When the command line does not specify what to push with `<refspec>...`
+arguments or `--all`, `--mirror`, `--tags` options, the command finds
+the default `<refspec>` by consulting `remote.*.push` configuration,
+and if it is not found, honors `push.default` configuration to decide
+what to push (See linkgit:git-config[1] for the meaning of `push.default`).
+
+
+OPTIONS[[OPTIONS]]
+------------------
 <repository>::
 	The "remote" repository that is destination of a push
-	operation.  See the section <<URLS,GIT URLS>> below.
-
-<refspec>::
-	The canonical format of a <refspec> parameter is
-	`+?<src>:<dst>`; that is, an optional plus `+`, followed
-	by the source ref, followed by a colon `:`, followed by
-	the destination ref.
-+
-The <src> side can be an
-arbitrary "SHA1 expression" that can be used as an
-argument to `git-cat-file -t`.  E.g. `master~4` (push
-four parents before the current master head).
-+
-The local ref that matches <src> is used
-to fast forward the remote ref that matches <dst>.  If
-the optional plus `+` is used, the remote ref is updated
-even if it does not result in a fast forward update.
-+
-Note: If no explicit refspec is found, (that is neither
-on the command line nor in any Push line of the
-corresponding remotes file---see below), then all the
-refs that exist both on the local side and on the remote
-side are updated.
+	operation.  This parameter can be either a URL
+	(see the section <<URLS,GIT URLS>> below) or the name
+	of a remote (see the section <<REMOTES,REMOTES>> below).
+
+<refspec>...::
+	Specify what destination ref to update with what source object.
+	The format of a <refspec> parameter is an optional plus
+	`+`, followed by the source object <src>, followed
+	by a colon `:`, followed by the destination ref <dst>.
 +
-`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
+The <src> is often the name of the branch you would want to push, but
+it can be any arbitrary "SHA-1 expression", such as `master~4` or
+`HEAD` (see linkgit:gitrevisions[7]).
++
+The <dst> tells which ref on the remote side is updated with this
+push. Arbitrary expressions cannot be used here, an actual ref must
+be named.
+If `git push [<repository>]` without any `<refspec>` argument is set to
+update some ref at the destination with `<src>` with
+`remote.<repository>.push` configuration variable, `:<dst>` part can
+be omitted---such a push will update a ref that `<src>` normally updates
+without any `<refspec>` on the command line.  Otherwise, missing
+`:<dst>` means to update the same ref as the `<src>`.
++
+The object referenced by <src> is used to update the <dst> reference
+on the remote side.  By default this is only allowed if <dst> is not
+a tag (annotated or lightweight), and then only if it can fast-forward
+<dst>.  By having the optional leading `+`, you can tell Git to update
+the <dst> ref even if it is not allowed by default (e.g., it is not a
+fast-forward.)  This does *not* attempt to merge <src> into <dst>.  See
+EXAMPLES below for details.
 +
-A parameter <ref> without a colon is equivalent to
-<ref>`:`<ref>, hence updates <ref> in the destination from <ref>
-in the source.
+`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
 +
 Pushing an empty <src> allows you to delete the <dst> ref from
 the remote repository.
++
+The special refspec `:` (or `+:` to allow non-fast-forward updates)
+directs Git to push "matching" branches: for every branch that exists on
+the local side, the remote side is updated if a branch of the same name
+already exists on the remote side.
+
+--all::
+	Push all branches (i.e. refs under `refs/heads/`); cannot be
+	used with other <refspec>.
 
-\--all::
+--prune::
+	Remove remote branches that don't have a local counterpart. For example
+	a remote branch `tmp` will be removed if a local branch with the same
+	name doesn't exist any more. This also respects refspecs, e.g.
+	`git push --prune remote refs/heads/*:refs/tmp/*` would
+	make sure that remote `refs/tmp/foo` will be removed if `refs/heads/foo`
+	doesn't exist.
+
+--mirror::
 	Instead of naming each ref to push, specifies that all
-	refs be pushed.
+	refs under `refs/` (which includes but is not
+	limited to `refs/heads/`, `refs/remotes/`, and `refs/tags/`)
+	be mirrored to the remote repository.  Newly created local
+	refs will be pushed to the remote end, locally updated refs
+	will be force updated on the remote end, and deleted refs
+	will be removed from the remote end.  This is the default
+	if the configuration option `remote.<remote>.mirror` is
+	set.
+
+-n::
+--dry-run::
+	Do everything except actually send the updates.
+
+--porcelain::
+	Produce machine-readable output.  The output status line for each ref
+	will be tab-separated and sent to stdout instead of stderr.  The full
+	symbolic names of the refs will be given.
 
-\--tags::
-	All refs under `$GIT_DIR/refs/tags` are pushed, in
+--delete::
+	All listed refs are deleted from the remote repository. This is
+	the same as prefixing all refs with a colon.
+
+--tags::
+	All refs under `refs/tags` are pushed, in
 	addition to refspecs explicitly listed on the command
 	line.
 
-\--receive-pack=<git-receive-pack>::
+--follow-tags::
+	Push all the refs that would be pushed without this option,
+	and also push annotated tags in `refs/tags` that are missing
+	from the remote but are pointing at commit-ish that are
+	reachable from the refs being pushed.  This can also be specified
+	with configuration variable 'push.followTags'.  For more
+	information, see 'push.followTags' in linkgit:git-config[1].
+
+--[no-]signed::
+--sign=(true|false|if-asked)::
+	GPG-sign the push request to update refs on the receiving
+	side, to allow it to be checked by the hooks and/or be
+	logged.  If `false` or `--no-signed`, no signing will be
+	attempted.  If `true` or `--signed`, the push will fail if the
+	server does not support signed pushes.  If set to `if-asked`,
+	sign if and only if the server supports signed pushes.  The push
+	will also fail if the actual call to `gpg --sign` fails.  See
+	linkgit:git-receive-pack[1] for the details on the receiving end.
+
+--[no-]atomic::
+	Use an atomic transaction on the remote side if available.
+	Either all refs are updated, or on error, no refs are updated.
+	If the server does not support atomic pushes the push will fail.
+
+--receive-pack=<git-receive-pack>::
+--exec=<git-receive-pack>::
 	Path to the 'git-receive-pack' program on the remote
 	end.  Sometimes useful when pushing to a remote
 	repository over ssh, and you do not have the program in
 	a directory on the default $PATH.
 
-\--exec=<git-receive-pack>::
-	Same as \--receive-pack=<git-receive-pack>.
+--[no-]force-with-lease::
+--force-with-lease=<refname>::
+--force-with-lease=<refname>:<expect>::
+	Usually, "git push" refuses to update a remote ref that is
+	not an ancestor of the local ref used to overwrite it.
++
+This option overrides this restriction if the current value of the
+remote ref is the expected value.  "git push" fails otherwise.
++
+Imagine that you have to rebase what you have already published.
+You will have to bypass the "must fast-forward" rule in order to
+replace the history you originally published with the rebased history.
+If somebody else built on top of your original history while you are
+rebasing, the tip of the branch at the remote may advance with her
+commit, and blindly pushing with `--force` will lose her work.
++
+This option allows you to say that you expect the history you are
+updating is what you rebased and want to replace. If the remote ref
+still points at the commit you specified, you can be sure that no
+other people did anything to the ref. It is like taking a "lease" on
+the ref without explicitly locking it, and the remote ref is updated
+only if the "lease" is still valid.
++
+`--force-with-lease` alone, without specifying the details, will protect
+all remote refs that are going to be updated by requiring their
+current value to be the same as the remote-tracking branch we have
+for them.
++
+`--force-with-lease=<refname>`, without specifying the expected value, will
+protect the named ref (alone), if it is going to be updated, by
+requiring its current value to be the same as the remote-tracking
+branch we have for it.
++
+`--force-with-lease=<refname>:<expect>` will protect the named ref (alone),
+if it is going to be updated, by requiring its current value to be
+the same as the specified value <expect> (which is allowed to be
+different from the remote-tracking branch we have for the refname,
+or we do not even have to have such a remote-tracking branch when
+this form is used).
++
+Note that all forms other than `--force-with-lease=<refname>:<expect>`
+that specifies the expected current value of the ref explicitly are
+still experimental and their semantics may change as we gain experience
+with this feature.
++
+"--no-force-with-lease" will cancel all the previous --force-with-lease on the
+command line.
 
--f, \--force::
+-f::
+--force::
 	Usually, the command refuses to update a remote ref that is
-	not a descendant of the local ref used to overwrite it.
-	This flag disables the check.  This can cause the
-	remote repository to lose commits; use it with care.
+	not an ancestor of the local ref used to overwrite it.
+	Also, when `--force-with-lease` option is used, the command refuses
+	to update a remote ref whose current value does not match
+	what is expected.
++
+This flag disables these checks, and can cause the remote repository
+to lose commits; use it with care.
++
+Note that `--force` applies to all the refs that are pushed, hence
+using it with `push.default` set to `matching` or with multiple push
+destinations configured with `remote.*.push` may overwrite refs
+other than the current branch (including local refs that are
+strictly behind their remote counterpart).  To force a push to only
+one branch, use a `+` in front of the refspec to push (e.g `git push
+origin +master` to force a push to the `master` branch). See the
+`<refspec>...` section above for details.
+
+--repo=<repository>::
+	This option is equivalent to the <repository> argument. If both
+	are specified, the command-line argument takes precedence.
 
-\--repo=<repo>::
-	When no repository is specified the command defaults to
-	"origin"; this overrides it.
+-u::
+--set-upstream::
+	For every branch that is up to date or successfully pushed, add
+	upstream (tracking) reference, used by argument-less
+	linkgit:git-pull[1] and other commands. For more information,
+	see 'branch.<name>.merge' in linkgit:git-config[1].
 
-\--thin, \--no-thin::
-	These options are passed to `git-send-pack`.  Thin
-	transfer spends extra cycles to minimize the number of
-	objects to be sent and meant to be used on slower connection.
+--[no-]thin::
+	These options are passed to linkgit:git-send-pack[1]. A thin transfer
+	significantly reduces the amount of sent data when the sender and
+	receiver share many of the same objects in common. The default is
+	\--thin.
+
+-q::
+--quiet::
+	Suppress all output, including the listing of updated refs,
+	unless an error occurs. Progress is not reported to the standard
+	error stream.
 
 -v::
+--verbose::
 	Run verbosely.
 
-include::urls.txt[]
+--progress::
+	Progress status is reported on the standard error stream
+	by default when it is attached to a terminal, unless -q
+	is specified. This flag forces progress status even if the
+	standard error stream is not directed to a terminal.
+
+--recurse-submodules=check|on-demand::
+	Make sure all submodule commits used by the revisions to be
+	pushed are available on a remote-tracking branch. If 'check' is
+	used Git will verify that all submodule commits that changed in
+	the revisions to be pushed are available on at least one remote
+	of the submodule. If any commits are missing the push will be
+	aborted and exit with non-zero status. If 'on-demand' is used
+	all submodules that changed in the revisions to be pushed will
+	be pushed. If on-demand was not able to push all necessary
+	revisions it will also be aborted and exit with non-zero status.
+
+--[no-]verify::
+	Toggle the pre-push hook (see linkgit:githooks[5]).  The
+	default is --verify, giving the hook a chance to prevent the
+	push.  With --no-verify, the hook is bypassed completely.

-Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>.
+The output of "git push" depends on the transport method used; this
+section describes the output when pushing over the Git protocol (either
+locally or via ssh).
+
+The status of the push is output in tabular form, with each line
+representing the status of a single ref. Each line is of the form:
+
+-------------------------------
+ <flag> <summary> <from> -> <to> (<reason>)
+-------------------------------
+
+If --porcelain is used, then each line of the output is of the form:
+
+-------------------------------
+ <flag> \t <from>:<to> \t <summary> (<reason>)
+-------------------------------
+
+The status of up-to-date refs is shown only if --porcelain or --verbose
+option is used.
+
+flag::
+	A single character indicating the status of the ref:
+(space);; for a successfully pushed fast-forward;
+`+`;; for a successful forced update;
+`-`;; for a successfully deleted ref;
+`*`;; for a successfully pushed new ref;
+`!`;; for a ref that was rejected or failed to push; and
+`=`;; for a ref that was up to date and did not need pushing.
+
+summary::
+	For a successfully pushed ref, the summary shows the old and new
+	values of the ref in a form suitable for using as an argument to
+	`git log` (this is `<old>..<new>` in most cases, and
+	`<old>...<new>` for forced non-fast-forward updates).
++
+For a failed update, more details are given:
++
+--
+rejected::
+	Git did not try to send the ref at all, typically because it
+	is not a fast-forward and you did not force the update.
+
+remote rejected::
+	The remote end refused the update.  Usually caused by a hook
+	on the remote side, or because the remote repository has one
+	of the following safety options in effect:
+	`receive.denyCurrentBranch` (for pushes to the checked out
+	branch), `receive.denyNonFastForwards` (for forced
+	non-fast-forward updates), `receive.denyDeletes` or
+	`receive.denyDeleteCurrent`.  See linkgit:git-config[1].
+
+remote failure::
+	The remote end did not report the successful update of the ref,
+	perhaps because of a temporary error on the remote side, a
+	break in the network connection, or other transient error.
+--
+
+from::
+	The name of the local ref being pushed, minus its
+	`refs/<type>/` prefix. In the case of deletion, the
+	name of the local ref is omitted.
+
+to::
+	The name of the remote ref being updated, minus its
+	`refs/<type>/` prefix.
+
+reason::
+	A human-readable explanation. In the case of successfully pushed
+	refs, no explanation is needed. For a failed ref, the reason for
+	failure is described.
+
+Note about fast-forwards
+------------------------
+
+When an update changes a branch (or more in general, a ref) that used to
+point at commit A to point at another commit B, it is called a
+fast-forward update if and only if B is a descendant of A.
+
+In a fast-forward update from A to B, the set of commits that the original
+commit A built on top of is a subset of the commits the new commit B
+builds on top of.  Hence, it does not lose any history.
+
+In contrast, a non-fast-forward update will lose history.  For example,
+suppose you and somebody else started at the same commit X, and you built
+a history leading to commit B while the other person built a history
+leading to commit A.  The history looks like this:
+
+----------------
+
+      B
+     /
+ ---X---A
+
+----------------
+
+Further suppose that the other person already pushed changes leading to A
+back to the original repository from which you two obtained the original
+commit X.
+
+The push done by the other person updated the branch that used to point at
+commit X to point at commit A.  It is a fast-forward.
+
+But if you try to push, you will attempt to update the branch (that
+now points at A) with commit B.  This does _not_ fast-forward.  If you did
+so, the changes introduced by commit A will be lost, because everybody
+will now start building on top of B.
+
+The command by default does not allow an update that is not a fast-forward
+to prevent such loss of history.
+
+If you do not want to lose your work (history from X to B) or the work by
+the other person (history from X to A), you would need to first fetch the
+history from the repository, create a history that contains changes done
+by both parties, and push the result back.
+
+You can perform "git pull", resolve potential conflicts, and "git push"
+the result.  A "git pull" will create a merge commit C between commits A
+and B.
+
+----------------
+
+      B---C
+     /   /
+ ---X---A
+
+----------------
+
+Updating A with the resulting merge commit will fast-forward and your
+push will be accepted.
+
+Alternatively, you can rebase your change between X and B on top of A,
+with "git pull --rebase", and push the result back.  The rebase will
+create a new commit D that builds the change between X and B on top of
+A.
+
+----------------
+
+      B   D
+     /   /
+ ---X---A
+
+----------------
+
+Again, updating A with this commit will fast-forward and your push will be
+accepted.
+
+There is another common situation where you may encounter non-fast-forward
+rejection when you try to push, and it is possible even when you are
+pushing into a repository nobody else pushes into. After you push commit
+A yourself (in the first picture in this section), replace it with "git
+commit --amend" to produce commit B, and you try to push it out, because
+forgot that you have pushed A out already. In such a case, and only if
+you are certain that nobody in the meantime fetched your earlier commit A
+(and started building on top of it), you can run "git push --force" to
+overwrite it. In other words, "git push --force" is a method reserved for
+a case where you do mean to lose history.
+
+
+Examples
+--------
+
+`git push`::
+	Works like `git push <remote>`, where <remote> is the
+	current branch's remote (or `origin`, if no remote is
+	configured for the current branch).
+
+`git push origin`::
+	Without additional configuration, pushes the current branch to
+	the configured upstream (`remote.origin.merge` configuration
+	variable) if it has the same name as the current branch, and
+	errors out without pushing otherwise.
++
+The default behavior of this command when no <refspec> is given can be
+configured by setting the `push` option of the remote, or the `push.default`
+configuration variable.
++
+For example, to default to pushing only the current branch to `origin`
+use `git config remote.origin.push HEAD`.  Any valid <refspec> (like
+the ones in the examples below) can be configured as the default for
+`git push origin`.
+
+`git push origin :`::
+	Push "matching" branches to `origin`. See
+	<refspec> in the <<OPTIONS,OPTIONS>> section above for a
+	description of "matching" branches.
+
+`git push origin master`::
+	Find a ref that matches `master` in the source repository
+	(most likely, it would find `refs/heads/master`), and update
+	the same ref (e.g. `refs/heads/master`) in `origin` repository
+	with it.  If `master` did not exist remotely, it would be
+	created.
+
+`git push origin HEAD`::
+	A handy way to push the current branch to the same name on the
+	remote.
+
+`git push mothership master:satellite/master dev:satellite/dev`::
+	Use the source ref that matches `master` (e.g. `refs/heads/master`)
+	to update the ref that matches `satellite/master` (most probably
+	`refs/remotes/satellite/master`) in the `mothership` repository;
+	do the same for `dev` and `satellite/dev`.
++
+This is to emulate `git fetch` run on the `mothership` using `git
+push` that is run in the opposite direction in order to integrate
+the work done on `satellite`, and is often necessary when you can
+only make connection in one way (i.e. satellite can ssh into
+mothership but mothership cannot initiate connection to satellite
+because the latter is behind a firewall or does not run sshd).
++
+After running this `git push` on the `satellite` machine, you would
+ssh into the `mothership` and run `git merge` there to complete the
+emulation of `git pull` that were run on `mothership` to pull changes
+made on `satellite`.
+
+`git push origin HEAD:master`::
+	Push the current branch to the remote ref matching `master` in the
+	`origin` repository. This form is convenient to push the current
+	branch without thinking about its local name.
+
+`git push origin master:refs/heads/experimental`::
+	Create the branch `experimental` in the `origin` repository
+	by copying the current `master` branch.  This form is only
+	needed to create a new branch or tag in the remote repository when
+	the local name and the remote name are different; otherwise,
+	the ref name on its own will work.
+
+`git push origin :experimental`::
+	Find a ref that matches `experimental` in the `origin` repository
+	(e.g. `refs/heads/experimental`), and delete it.
+
+`git push origin +dev:master`::
+	Update the origin repository's master branch with the dev branch,
+	allowing non-fast-forward updates.  *This can leave unreferenced
+	commits dangling in the origin repository.*  Consider the
+	following situation, where a fast-forward is not possible:
++
+----
+	    o---o---o---A---B  origin/master
+		     \
+		      X---Y---Z  dev
+----
++
+The above command would change the origin repository to
++
+----
+		      A---B  (unnamed branch)
+		     /
+	    o---o---o---X---Y---Z  master
+----
++
+Commits A and B would no longer belong to a branch with a symbolic name,
+and so would be unreachable.  As such, these commits would be removed by
+a `git gc` command on the origin repository.

 DESCRIPTION
 -----------
 Reads the tree information given by <tree-ish> into the index,
 but does not actually *update* any of the files it "caches". (see:
-gitlink:git-checkout-index[1])
+linkgit:git-checkout-index[1])
 
 Optionally, it can merge a tree into the index, perform a
 fast-forward (i.e. 2-way) merge, or a 3-way merge, with the `-m`
 flag.  When used with `-m`, the `-u` flag causes it to also update
 the files in the work tree with the result of the merge.
 
-Trivial merges are done by `git-read-tree` itself.  Only conflicting paths
-will be in unmerged state when `git-read-tree` returns.

+Sparse checkout
+---------------

+"Sparse checkout" allows populating the working directory sparsely.
+It uses the skip-worktree bit (see linkgit:git-update-index[1]) to tell
+Git whether a file in the working directory is worth looking at.
+
+'git read-tree' and other merge-based commands ('git merge', 'git
+checkout'...) can help maintaining the skip-worktree bitmap and working
+directory update. `$GIT_DIR/info/sparse-checkout` is used to
+define the skip-worktree reference bitmap. When 'git read-tree' needs
+to update the working directory, it resets the skip-worktree bit in the index
+based on this file, which uses the same syntax as .gitignore files.
+If an entry matches a pattern in this file, skip-worktree will not be
+set on that entry. Otherwise, skip-worktree will be set.
+
+Then it compares the new skip-worktree value with the previous one. If
+skip-worktree turns from set to unset, it will add the corresponding
+file back. If it turns from unset to set, that file will be removed.
+
+While `$GIT_DIR/info/sparse-checkout` is usually used to specify what
+files are in, you can also specify what files are _not_ in, using
+negate patterns. For example, to remove the file `unwanted`:
 
+----------------
+/*
+!unwanted
+----------------
+
+Another tricky thing is fully repopulating the working directory when you
+no longer want sparse checkout. You cannot just disable "sparse
+checkout" because skip-worktree bits are still in the index and your working
+directory is still sparsely populated. You should re-populate the working
+directory with the `$GIT_DIR/info/sparse-checkout` file content as

++
+You may execute several commands by either using one instance of `--exec`
+with several commands:

+	git rebase -i --exec "cmd1 && cmd2 && ..."
++
+or by giving more than one `--exec`:
++
+	git rebase -i --exec "cmd1" --exec "cmd2" --exec ...
++
+If `--autosquash` is used, "exec" lines will not be appended for
+the intermediate commits, and will only appear at the end of each
+squash/fixup series.
+
+--root::
+	Rebase all commits reachable from <branch>, instead of
+	limiting them with an <upstream>.  This allows you to rebase
+	the root commit(s) on a branch.  When used with --onto, it
+	will skip changes already contained in <newbase> (instead of
+	<upstream>) whereas without --onto it will operate on every change.
+	When used together with both --onto and --preserve-merges,
+	'all' root commits will be rewritten to have <newbase> as parent
+	instead.
+
+--autosquash::
+--no-autosquash::
+	When the commit log message begins with "squash! ..." (or
+	"fixup! ..."), and there is a commit whose title begins with
+	the same ..., automatically modify the todo list of rebase -i
+	so that the commit marked for squashing comes right after the
+	commit to be modified, and change the action of the moved
+	commit from `pick` to `squash` (or `fixup`).  Ignores subsequent
+	"fixup! " or "squash! " after the first, in case you referred to an
+	earlier fixup/squash with `git commit --fixup/--squash`.
++
+This option is only valid when the '--interactive' option is used.
++
+If the '--autosquash' option is enabled by default using the
+configuration variable `rebase.autoSquash`, this option can be
+used to override and disable this setting.
+
+--[no-]autostash::
+	Automatically create a temporary stash before the operation
+	begins, and apply it after the operation ends.  This means
+	that you can run rebase on a dirty worktree.  However, use
+	with care: the final stash application after a successful
+	rebase might result in non-trivial conflicts.
+
+--no-ff::
+	With --interactive, cherry-pick all rebased commits instead of
+	fast-forwarding over the unchanged ones.  This ensures that the
+	entire history of the rebased branch is composed of new commits.
++
+Without --interactive, this is a synonym for --force-rebase.
++
+You may find this helpful after reverting a topic branch merge, as this option
+recreates the topic branch with fresh commits so it can be remerged
+successfully without needing to "revert the reversion" (see the
+link:howto/revert-a-faulty-merge.html[revert-a-faulty-merge How-To] for details).

+
+INTERACTIVE MODE
+----------------
+
+Rebasing interactively means that you have a chance to edit the commits
+which are rebased.  You can reorder the commits, and you can
+remove them (weeding out bad or otherwise unwanted patches).
+
+The interactive mode is meant for this type of workflow:
+
+1. have a wonderful idea
+2. hack on the code
+3. prepare a series for submission
+4. submit
+
+where point 2. consists of several instances of
+
+a) regular use
+
+ 1. finish something worthy of a commit
+ 2. commit
+
+b) independent fixup
+
+ 1. realize that something does not work
+ 2. fix that
+ 3. commit it
+
+Sometimes the thing fixed in b.2. cannot be amended to the not-quite
+perfect commit it fixes, because that commit is buried deeply in a
+patch series.  That is exactly what interactive rebase is for: use it
+after plenty of "a"s and "b"s, by rearranging and editing
+commits, and squashing multiple commits into one.
+
+Start it with the last commit you want to retain as-is:
+
+	git rebase -i <after-this-commit>
+
+An editor will be fired up with all the commits in your current branch
+(ignoring merge commits), which come after the given commit.  You can
+reorder the commits in this list to your heart's content, and you can
+remove them.  The list looks more or less like this:
+
+-------------------------------------------
+pick deadbee The oneline of this commit
+pick fa1afe1 The oneline of the next commit
+...
+-------------------------------------------
+
+The oneline descriptions are purely for your pleasure; 'git rebase' will
+not look at them but at the commit names ("deadbee" and "fa1afe1" in this
+example), so do not delete or edit the names.
+
+By replacing the command "pick" with the command "edit", you can tell
+'git rebase' to stop after applying that commit, so that you can edit
+the files and/or the commit message, amend the commit, and continue
+rebasing.
+
+If you just want to edit the commit message for a commit, replace the
+command "pick" with the command "reword".
+
+To drop a commit, replace the command "pick" with "drop", or just
+delete the matching line.
+
+If you want to fold two or more commits into one, replace the command
+"pick" for the second and subsequent commits with "squash" or "fixup".
+If the commits had different authors, the folded commit will be
+attributed to the author of the first commit.  The suggested commit
+message for the folded commit is the concatenation of the commit
+messages of the first commit and of those with the "squash" command,
+but omits the commit messages of commits with the "fixup" command.
+
+'git rebase' will stop when "pick" has been replaced with "edit" or
+when a command fails due to merge errors. When you are done editing
+and/or resolving conflicts you can continue with `git rebase --continue`.
+
+For example, if you want to reorder the last 5 commits, such that what
+was HEAD~4 becomes the new HEAD. To achieve that, you would call
+'git rebase' like this:
+
+----------------------
+$ git rebase -i HEAD~5
+----------------------
+
+And move the first patch to the end of the list.
+
+You might want to preserve merges, if you have a history like this:
+
+------------------
+           X
+            \
+         A---M---B
+        /
+---o---O---P---Q
+------------------
+
+Suppose you want to rebase the side branch starting at "A" to "Q". Make
+sure that the current HEAD is "B", and call

+-----------------------------
+$ git rebase -i -p --onto Q O
+-----------------------------
 
-Documentation
---------------
-Documentation by Junio C Hamano and the git-list <git@vger.kernel.org>.
+Reordering and editing commits usually creates untested intermediate
+steps.  You may want to check that your history editing did not break
+anything by running a test, or at least recompiling at intermediate
+points in history by using the "exec" command (shortcut "x").  You may
+do so by creating a todo list like this one:
+
+-------------------------------------------
+pick deadbee Implement feature XXX
+fixup f1a5c00 Fix to feature XXX
+exec make
+pick c0ffeee The oneline of the next commit
+edit deadbab The oneline of the commit after
+exec cd subdir; make test
+...
+-------------------------------------------
+
+The interactive rebase will stop when a command fails (i.e. exits with
+non-0 status) to give you an opportunity to fix the problem. You can
+continue with `git rebase --continue`.
+
+The "exec" command launches the command in a shell (the one specified
+in `$SHELL`, or the default shell if `$SHELL` is not set), so you can
+use shell features (like "cd", ">", ";" ...). The command is run from
+the root of the working tree.
+
+----------------------------------
+$ git rebase -i --exec "make test"
+----------------------------------
+
+This command lets you check that intermediate commits are compilable.
+The todo list becomes like that:
+
+--------------------
+pick 5928aea one
+exec make test
+pick 04d0fda two
+exec make test
+pick ba46169 three
+exec make test
+pick f4593f9 four
+exec make test
+--------------------
+
+SPLITTING COMMITS
+-----------------
+
+In interactive mode, you can mark commits with the action "edit".  However,
+this does not necessarily mean that 'git rebase' expects the result of this
+edit to be exactly one commit.  Indeed, you can undo the commit, or you can
+add other commits.  This can be used to split a commit into two:
+
+- Start an interactive rebase with `git rebase -i <commit>^`, where
+  <commit> is the commit you want to split.  In fact, any commit range
+  will do, as long as it contains that commit.
+
+- Mark the commit you want to split with the action "edit".
+
+- When it comes to editing that commit, execute `git reset HEAD^`.  The
+  effect is that the HEAD is rewound by one, and the index follows suit.
+  However, the working tree stays the same.
+
+- Now add the changes to the index that you want to have in the first
+  commit.  You can use `git add` (possibly interactively) or
+  'git gui' (or both) to do that.
+
+- Commit the now-current index with whatever commit message is appropriate
+  now.
+
+- Repeat the last two steps until your working tree is clean.
+
+- Continue the rebase with `git rebase --continue`.
+
+If you are not absolutely sure that the intermediate revisions are
+consistent (they compile, pass the testsuite, etc.) you should use
+'git stash' to stash away the not-yet-committed changes
+after each commit, test, and amend the commit if fixes are necessary.
+
+
+RECOVERING FROM UPSTREAM REBASE
+-------------------------------
+
+Rebasing (or any other form of rewriting) a branch that others have
+based work on is a bad idea: anyone downstream of it is forced to
+manually fix their history.  This section explains how to do the fix
+from the downstream's point of view.  The real fix, however, would be
+to avoid rebasing the upstream in the first place.
+
+To illustrate, suppose you are in a situation where someone develops a
+'subsystem' branch, and you are working on a 'topic' that is dependent
+on this 'subsystem'.  You might end up with a history like the
+following:
+
+------------
+    o---o---o---o---o---o---o---o---o  master
+	 \
+	  o---o---o---o---o  subsystem
+			   \
+			    *---*---*  topic
+------------
+
+If 'subsystem' is rebased against 'master', the following happens:
+
+------------
+    o---o---o---o---o---o---o---o  master
+	 \			 \
+	  o---o---o---o---o	  o'--o'--o'--o'--o'  subsystem
+			   \
+			    *---*---*  topic
+------------
+
+If you now continue development as usual, and eventually merge 'topic'
+to 'subsystem', the commits from 'subsystem' will remain duplicated forever:
+
+------------
+    o---o---o---o---o---o---o---o  master
+	 \			 \
+	  o---o---o---o---o	  o'--o'--o'--o'--o'--M	 subsystem
+			   \			     /
+			    *---*---*-..........-*--*  topic
+------------
+
+Such duplicates are generally frowned upon because they clutter up
+history, making it harder to follow.  To clean things up, you need to
+transplant the commits on 'topic' to the new 'subsystem' tip, i.e.,
+rebase 'topic'.  This becomes a ripple effect: anyone downstream from
+'topic' is forced to rebase too, and so on!
+
+There are two kinds of fixes, discussed in the following subsections:
+
+Easy case: The changes are literally the same.::
+
+	This happens if the 'subsystem' rebase was a simple rebase and
+	had no conflicts.
+
+Hard case: The changes are not the same.::
+
+	This happens if the 'subsystem' rebase had conflicts, or used
+	`--interactive` to omit, edit, squash, or fixup commits; or
+	if the upstream used one of `commit --amend`, `reset`, or
+	`filter-branch`.
+
+
+The easy case
+~~~~~~~~~~~~~
+
+Only works if the changes (patch IDs based on the diff contents) on
+'subsystem' are literally the same before and after the rebase
+'subsystem' did.
+
+In that case, the fix is easy because 'git rebase' knows to skip
+changes that are already present in the new upstream.  So if you say
+(assuming you're on 'topic')
+------------
+    $ git rebase subsystem
+------------
+you will end up with the fixed history
+------------
+    o---o---o---o---o---o---o---o  master
+				 \
+				  o'--o'--o'--o'--o'  subsystem
+						   \
+						    *---*---*  topic
+------------
+
+
+The hard case
+~~~~~~~~~~~~~
+
+Things get more complicated if the 'subsystem' changes do not exactly
+correspond to the ones before the rebase.
+
+NOTE: While an "easy case recovery" sometimes appears to be successful
+      even in the hard case, it may have unintended consequences.  For
+      example, a commit that was removed via `git rebase
+      --interactive` will be **resurrected**!
+
+The idea is to manually tell 'git rebase' "where the old 'subsystem'
+ended and your 'topic' began", that is, what the old merge-base
+between them was.  You will have to find a way to name the last commit
+of the old 'subsystem', for example:
+
+* With the 'subsystem' reflog: after 'git fetch', the old tip of
+  'subsystem' is at `subsystem@{1}`.  Subsequent fetches will
+  increase the number.  (See linkgit:git-reflog[1].)
+
+* Relative to the tip of 'topic': knowing that your 'topic' has three
+  commits, the old tip of 'subsystem' must be `topic~3`.
+
+You can then transplant the old `subsystem..topic` to the new tip by
+saying (for the reflog case, and assuming you are on 'topic' already):
+------------
+    $ git rebase --onto subsystem subsystem@{1}
+------------
+
+The ripple effect of a "hard case" recovery is especially bad:
+'everyone' downstream from 'topic' will now have to perform a "hard
+case" recovery too!
+
+BUGS
+----
+The todo list presented by `--preserve-merges --interactive` does not
+represent the topology of the revision graph.  Editing commits and
+rewording their commit messages should work fine, but attempts to
+reorder commits tend to produce counterintuitive results.
+
+For example, an attempt to rearrange
+------------
+1 --- 2 --- 3 --- 4 --- 5
+------------
+to
+------------
+1 --- 2 --- 4 --- 3 --- 5
+------------
+by moving the "pick 4" line will result in the following history:
+------------
+	3
+       /
+1 --- 2 --- 4 --- 5

+while refs to be deleted will have sha1-new equal to 0\{40}, otherwise
+sha1-old and sha1-new should be valid objects in the repository.
+
+When accepting a signed push (see linkgit:git-push[1]), the signed
+push certificate is stored in a blob and an environment variable
+`GIT_PUSH_CERT` can be consulted for its object name.  See the
+description of `post-receive` hook for an example.  In addition, the
+certificate is verified using GPG and the result is exported with
+the following environment variables:
+
+`GIT_PUSH_CERT_SIGNER`::
+	The name and the e-mail address of the owner of the key that
+	signed the push certificate.
+
+`GIT_PUSH_CERT_KEY`::
+	The GPG key ID of the key that signed the push certificate.
+
+`GIT_PUSH_CERT_STATUS`::
+	The status of GPG verification of the push certificate,
+	using the same mnemonic as used in `%G?` format of `git log`
+	family of commands (see linkgit:git-log[1]).
+
+`GIT_PUSH_CERT_NONCE`::
+	The nonce string the process asked the signer to include
+	in the push certificate.  If this does not match the value
+	recorded on the "nonce" header in the push certificate, it
+	may indicate that the certificate is a valid one that is
+	being replayed from a separate "git push" session.
+
+`GIT_PUSH_CERT_NONCE_STATUS`::
+`UNSOLICITED`;;
+	"git push --signed" sent a nonce when we did not ask it to
+	send one.
+`MISSING`;;
+	"git push --signed" did not send any nonce header.
+`BAD`;;
+	"git push --signed" sent a bogus nonce.
+`OK`;;
+	"git push --signed" sent the nonce we asked it to send.
+`SLOP`;;
+	"git push --signed" sent a nonce different from what we
+	asked it to send now, but in a previous session.  See
+	`GIT_PUSH_CERT_NONCE_SLOP` environment variable.
+
+`GIT_PUSH_CERT_NONCE_SLOP`::
+	"git push --signed" sent a nonce different from what we
+	asked it to send now, but in a different session whose
+	starting time is different by this many seconds from the
+	current session.  Only meaningful when
+	`GIT_PUSH_CERT_NONCE_STATUS` says `SLOP`.
+	Also read about `receive.certNonceSlop` variable in
+	linkgit:git-config[1].
+
+This hook is called before any refname is updated and before any
+fast-forward checks are performed.
+
+If the pre-receive hook exits with a non-zero exit status no updates
+will be performed, and the update, post-receive and post-update
+hooks will not be invoked either.  This can be useful to quickly
+bail out if the update is not to be supported.
+
+update Hook
+-----------
+Before each ref is updated, if $GIT_DIR/hooks/update file exists
+and is executable, it is invoked once per ref, with three parameters:
 
-The hook should exit with non-zero status if it wants to
-disallow updating the named ref.  Otherwise it should exit with
-zero.
+       $GIT_DIR/hooks/update refname sha1-old sha1-new
 
-Using this hook, it is easy to generate mails on updates to
-the local repository. This example script sends a mail with
-the commits pushed to the repository:
+The refname parameter is relative to $GIT_DIR; e.g. for the master
+head this is "refs/heads/master".  The two sha1 arguments are
+the object names for the refname before and after the update.
+Note that the hook is called before the refname is updated,
+so either sha1-old is 0\{40} (meaning there is no such ref yet),
+or it should match what is recorded in refname.
+
+The hook should exit with non-zero status if it wants to disallow
+updating the named ref.  Otherwise it should exit with zero.
+
+Successful execution (a zero exit status) of this hook does not
+ensure the ref will actually be updated, it is only a prerequisite.
+As such it is not a good idea to send notices (e.g. email) from
+this hook.  Consider using the post-receive hook instead.
+
+post-receive Hook
+-----------------
+After all refs were updated (or attempted to be updated), if any
+ref update was successful, and if $GIT_DIR/hooks/post-receive
+file exists and is executable, it will be invoked once with no
+parameters.  The standard input of the hook will be one line
+for each successfully updated ref:
+
+       sha1-old SP sha1-new SP refname LF
+
+The refname value is relative to $GIT_DIR; e.g. for the master
+head this is "refs/heads/master".  The two sha1 values before
+each refname are the object names for the refname before and after
+the update.  Refs that were created will have sha1-old equal to
+0\{40}, while refs that were deleted will have sha1-new equal to
+0\{40}, otherwise sha1-old and sha1-new should be valid objects in
+the repository.
+
+The `GIT_PUSH_CERT*` environment variables can be inspected, just as
+in `pre-receive` hook, after accepting a signed push.
+
+Using this hook, it is easy to generate mails describing the updates
+to the repository.  This example script sends one mail message per
+ref listing the commits pushed to the repository, and logs the push
+certificates of signed pushes with good signatures to a logger
+service:
 
 	#!/bin/sh
 	# mail out commit update information.
-	if expr "$2" : '0*$' >/dev/null
+	while read oval nval ref
+	do
+		if expr "$oval" : '0*$' >/dev/null
+		then
+			echo "Created a new ref, with the following commits:"
+			git rev-list --pretty "$nval"
+		else
+			echo "New commits:"
+			git rev-list --pretty "$nval" "^$oval"
+		fi |
+		mail -s "Changes to ref $ref" commit-list@mydomain
+	done
+	# log signed push certificate, if any
+	if test -n "${GIT_PUSH_CERT-}" && test ${GIT_PUSH_CERT_STATUS} = G
 	then
-		echo "Created a new ref, with the following commits:"
-		git-rev-list --pretty "$2"
-	else
-		echo "New commits:"
-		git-rev-list --pretty "$3" "^$2"
-	fi |
-	mail -s "Changes to ref $1" commit-list@mydomain
+		(
+			echo expected nonce is ${GIT_PUSH_NONCE}
+			git cat-file blob ${GIT_PUSH_CERT}
+		) | mail -s "push certificate from $GIT_PUSH_CERT_SIGNER" push-log@mydomain
+	fi
 	exit 0
 
-Another hook $GIT_DIR/hooks/post-update, if exists and
-executable, is called with the list of refs that have been
-updated.  This can be used to implement repository wide cleanup
-task if needed.  The exit code from this hook invocation is
-ignored; the only thing left for git-receive-pack to do at that
-point is to exit itself anyway.  This hook can be used, for
-example, to run "git-update-server-info" if the repository is
-packed and is served via a dumb transport.
+The exit code from this hook invocation is ignored, however a
+non-zero exit code will generate an error message.
 
-	#!/bin/sh
-	exec git-update-server-info
+Note that it is possible for refname to not have sha1-new when this
+hook runs.  This can easily occur if another user modifies the ref
+after it was updated by 'git-receive-pack', but before the hook was able
+to evaluate it.  It is recommended that hooks rely on sha1-new
+rather than the current value of refname.
 
-There are other real-world examples of using update and
-post-update hooks found in the Documentation/howto directory.
+post-update Hook
+----------------
+After all other processing, if at least one ref was updated, and
+if $GIT_DIR/hooks/post-update file exists and is executable, then
+post-update will be called with the list of refs that have been updated.
+This can be used to implement any repository wide cleanup tasks.
 
-git-receive-pack honours the receive.denyNonFastforwards flag, which
-tells it if updates to a ref should be denied if they are not fast-forwards.
+The exit code from this hook invocation is ignored; the only thing
+left for 'git-receive-pack' to do at that point is to exit itself
+anyway.

 DESCRIPTION
@@ -16,53 +17,117 @@ The command takes various subcommands, and different options
 depending on the subcommand:
 
 [verse]

+'git reflog exists' <ref>
+
+Reference logs, or "reflogs", record when the tips of branches and
+other references were updated in the local repository. Reflogs are
+useful in various Git commands, to specify the old value of a
+reference. For example, `HEAD@{2}` means "where HEAD used to be two
+moves ago", `master@{one.week.ago}` means "where master used to point
+to one week ago in this local repository", and so on. See
+linkgit:gitrevisions[7] for more details.
+
+This command manages the information recorded in the reflogs.
+
+The "show" subcommand (which is also the default, in the absence of
+any subcommands) shows the log of the reference provided in the
+command-line (or `HEAD`, by default). The reflog covers all recent
+actions, and in addition the `HEAD` reflog records branch switching.
+`git reflog show` is an alias for `git log -g --abbrev-commit
+--pretty=oneline`; see linkgit:git-log[1] for more information.
+
+The "expire" subcommand prunes older reflog entries. Entries older
+than `expire` time, or entries older than `expire-unreachable` time
+and not reachable from the current tip, are removed from the reflog.
+This is typically not used directly by end users -- instead, see
+linkgit:git-gc[1].
+
+The "delete" subcommand deletes single entries from the reflog. Its
+argument must be an _exact_ entry (e.g. "`git reflog delete
+master@{2}`"). This subcommand is also typically not used directly by
+end users.
+
+The "exists" subcommand checks whether a ref has a reflog.  It exits
+with zero status if the reflog exists, and non-zero status if it does
+not.

+OPTIONS
+-------
 
-Reflog is a mechanism to record when the tip of branches are
-updated.  This command is to manage the information recorded in it.
+Options for `show`
+~~~~~~~~~~~~~~~~~~
 
-The subcommand "expire" is used to prune older reflog entries.
-Entries older than `expire` time, or entries older than
-`expire-unreachable` time and are not reachable from the current
-tip, are removed from the reflog.  This is typically not used

+Options for `expire`
+~~~~~~~~~~~~~~~~~~~~
 
-OPTIONS
--------
+--all::
+	Process the reflogs of all references.
 
 --expire=<time>::
-	Entries older than this time are pruned.  Without the
-	option it is taken from configuration `gc.reflogExpire`,
-	which in turn defaults to 90 days.
+	Prune entries older than the specified time. If this option is
+	not specified, the expiration time is taken from the
+	configuration setting `gc.reflogExpire`, which in turn
+	defaults to 90 days. `--expire=all` prunes entries regardless
+	of their age; `--expire=never` turns off pruning of reachable
+	entries (but see `--expire-unreachable`).
 
 --expire-unreachable=<time>::
-	Entries older than this time and are not reachable from
-	the current tip of the branch are pruned.  Without the
-	option it is taken from configuration
-	`gc.reflogExpireUnreachable`, which in turn defaults to
-	30 days.
-
---all::
-	Instead of listing <refs> explicitly, prune all refs.
+	Prune entries older than `<time>` that are not reachable from
+	the current tip of the branch. If this option is not
+	specified, the expiration time is taken from the configuration
+	setting `gc.reflogExpireUnreachable`, which in turn defaults
+	to 30 days. `--expire-unreachable=all` prunes unreachable
+	entries regardless of their age; `--expire-unreachable=never`
+	turns off early pruning of unreachable entries (but see
+	`--expire`).
+
+--updateref::
+	Update the reference to the value of the top reflog entry (i.e.
+	<ref>@\{0\}) if the previous top entry was pruned.  (This
+	option is ignored for symbolic references.)
+
+--rewrite::
+	If a reflog entry's predecessor is pruned, adjust its "old"
+	SHA-1 to be equal to the "new" SHA-1 field of the entry that
+	now precedes it.
+
+--stale-fix::
+	Prune any reflog entries that point to "broken commits". A
+	broken commit is a commit that is not reachable from any of
+	the reference tips and that refers, directly or indirectly, to
+	a missing commit, tree, or blob object.
++
+This computation involves traversing all the reachable objects, i.e. it
+has the same cost as 'git prune'.  It is primarily intended to fix
+corruption caused by garbage collecting using older versions of Git,
+which didn't protect objects referred to by reflogs.
+
+-n::
+--dry-run::
+	Do not actually prune any entries; just show what would have
+	been pruned.
+
+--verbose::
+	Print extra information on screen.
+
+
+Options for `delete`
+~~~~~~~~~~~~~~~~~~~~
+
+`git reflog delete` accepts options `--updateref`, `--rewrite`, `-n`,
+`--dry-run`, and `--verbose`, with the same meanings as when they are
+used with `expire`.

+=================
+
+NAME
+----
+git-remote-ext - Bridge smart transport to external command.
+
+SYNOPSIS
+--------
+[verse]
+git remote add <nick> "ext::<command>[ <arguments>...]"
+
+DESCRIPTION
+-----------
+This remote helper uses the specified '<command>' to connect
+to a remote Git server.
+
+Data written to stdin of the specified '<command>' is assumed
+to be sent to a git:// server, git-upload-pack, git-receive-pack
+or git-upload-archive (depending on situation), and data read
+from stdout of <command> is assumed to be received from
+the same service.
+
+Command and arguments are separated by an unescaped space.
+
+The following sequences have a special meaning:
+
+'% '::
+	Literal space in command or argument.
+
+'%%'::
+	Literal percent sign.
+
+'%s'::
+	Replaced with name (receive-pack, upload-pack, or
+	upload-archive) of the service Git wants to invoke.
+
+'%S'::
+	Replaced with long name (git-receive-pack,
+	git-upload-pack, or git-upload-archive) of the service
+	Git wants to invoke.
+
+'%G' (must be the first characters in an argument)::
+	This argument will not be passed to '<command>'. Instead, it
+	will cause the helper to start by sending git:// service requests to
+	the remote side with the service field set to an appropriate value and
+	the repository field set to rest of the argument. Default is not to send
+	such a request.
++
+This is useful if remote side is git:// server accessed over
+some tunnel.
+
+'%V' (must be first characters in argument)::
+	This argument will not be passed to '<command>'. Instead it sets
+	the vhost field in the git:// service request (to rest of the argument).
+	Default is not to send vhost in such request (if sent).
+
+ENVIRONMENT VARIABLES:
+----------------------
+
+GIT_TRANSLOOP_DEBUG::
+	If set, prints debugging information about various reads/writes.
+
+ENVIRONMENT VARIABLES PASSED TO COMMAND:
+----------------------------------------
+
+GIT_EXT_SERVICE::
+	Set to long name (git-upload-pack, etc...) of service helper needs
+	to invoke.
+
+GIT_EXT_SERVICE_NOPREFIX::
+	Set to long name (upload-pack, etc...) of service helper needs
+	to invoke.
+
+
+EXAMPLES:
+---------
+This remote helper is transparently used by Git when
+you use commands such as "git fetch <URL>", "git clone <URL>",
+, "git push <URL>" or "git remote add <nick> <URL>", where <URL>
+begins with `ext::`.  Examples:
+
+"ext::ssh -i /home/foo/.ssh/somekey user&#64;host.example %S 'foo/repo'"::
+	Like host.example:foo/repo, but use /home/foo/.ssh/somekey as
+	keypair and user as user on remote side. This avoids needing to
+	edit .ssh/config.
+
+"ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"::
+	Represents repository with path /somerepo accessible over
+	git protocol at abstract namespace address /git-server.
+
+"ext::git-server-alias foo %G/repo"::
+	Represents a repository with path /repo accessed using the
+	helper program "git-server-alias foo".  The path to the
+	repository and type of request are not passed on the command
+	line but as part of the protocol stream, as usual with git://
+	protocol.
+
+"ext::git-server-alias foo %G/repo %Vfoo"::
+	Represents a repository with path /repo accessed using the
+	helper program "git-server-alias foo".  The hostname for the
+	remote server passed in the protocol stream will be "foo"
+	(this allows multiple virtual Git servers to share a
+	link-level address).
+
+"ext::git-server-alias foo %G/repo% with% spaces %Vfoo"::
+	Represents a repository with path '/repo with spaces' accessed
+	using the helper program "git-server-alias foo".  The hostname for
+	the remote server passed in the protocol stream will be "foo"
+	(this allows multiple virtual Git servers to share a
+	link-level address).
+
+"ext::git-ssl foo.example /bar"::
+	Represents a repository accessed using the helper program
+	"git-ssl foo.example /bar".  The type of request can be
+	determined by the helper using environment variables (see
+	above).

+NAME
+----
+git-remote-fd - Reflect smart transport stream back to caller
+
+SYNOPSIS
+--------
+"fd::<infd>[,<outfd>][/<anything>]" (as URL)
+
+DESCRIPTION
+-----------
+This helper uses specified file descriptors to connect to a remote Git server.
+This is not meant for end users but for programs and scripts calling git
+fetch, push or archive.
+
+If only <infd> is given, it is assumed to be a bidirectional socket connected
+to remote Git server (git-upload-pack, git-receive-pack or
+git-upload-achive). If both <infd> and <outfd> are given, they are assumed
+to be pipes connected to a remote Git server (<infd> being the inbound pipe
+and <outfd> being the outbound pipe.
+
+It is assumed that any handshaking procedures have already been completed
+(such as sending service request for git://) before this helper is started.
+
+<anything> can be any string. It is ignored. It is meant for providing
+information to user in the URL in case that URL is displayed in some
+context.
+
+ENVIRONMENT VARIABLES
+---------------------
+GIT_TRANSLOOP_DEBUG::
+	If set, prints debugging information about various reads/writes.
+
+EXAMPLES
+--------
+`git fetch fd::17 master`::
+	Fetch master, using file descriptor #17 to communicate with
+	git-upload-pack.
+
+`git fetch fd::17/foo master`::
+	Same as above.
+
+`git push fd::7,8 master (as URL)`::
+	Push master, using file descriptor #7 to read data from
+	git-receive-pack and file descriptor #8 to write data to
+	same service.
+
+`git push fd::7,8/bar master`::
+	Same as above.

+'refs/' on the remote will be directly mirrored into 'refs/' in the
+local repository. This option only makes sense in bare repositories,
+because a fetch would overwrite any local commits.
++
+When a push mirror is created with `--mirror=push`, then `git push`
+will always behave as if `--mirror` was passed.
+
+'rename'::
+
+Rename the remote named <old> to <new>. All remote-tracking branches and
+configuration settings for the remote are updated.
++
+In case <old> and <new> are the same, and <old> is a file under
+`$GIT_DIR/remotes` or `$GIT_DIR/branches`, the remote is converted to
+the configuration file format.

+'remove'::
+'rm'::
+
+Remove the remote named <name>. All remote-tracking branches and
+configuration settings for the remote are removed.
+
+'set-head'::
+
+Sets or deletes the default branch (i.e. the target of the
+symbolic-ref `refs/remotes/<name>/HEAD`) for
+the named remote. Having a default branch for a remote is not required,
+but allows the name of the remote to be specified in lieu of a specific
+branch. For example, if the default branch for `origin` is set to
+`master`, then `origin` may be specified wherever you would normally
+specify `origin/master`.
++
+With `-d` or `--delete`, the symbolic ref `refs/remotes/<name>/HEAD` is deleted.
++
+With `-a` or `--auto`, the remote is queried to determine its `HEAD`, then the
+symbolic-ref `refs/remotes/<name>/HEAD` is set to the same branch. e.g., if the remote
+`HEAD` is pointed at `next`, "`git remote set-head origin -a`" will set
+the symbolic-ref `refs/remotes/origin/HEAD` to `refs/remotes/origin/next`. This will
+only work if `refs/remotes/origin/next` already exists; if not it must be

+`refs/remotes/origin/master`. This will only work if
+`refs/remotes/origin/master` already exists; if not it must be fetched first.
++
+
+'set-branches'::
+
+Changes the list of branches tracked by the named remote.
+This can be used to track a subset of the available remote branches
+after the initial setup for a remote.
++
+The named branches will be interpreted as if specified with the
+`-t` option on the 'git remote add' command line.
++
+With `--add`, instead of replacing the list of currently tracked
+branches, adds to that list.
+
+'set-url'::
+
+Changes URLs for the remote. Sets first URL for remote <name> that matches
+regex <oldurl> (first URL if no <oldurl> is given) to <newurl>. If
+<oldurl> doesn't match any URL, an error occurs and nothing is changed.
++
+With '--push', push URLs are manipulated instead of fetch URLs.
++
+With '--add', instead of changing existing URLs, new URL is added.
++
+With '--delete', instead of changing existing URLs, all URLs matching
+regex <url> are deleted for remote <name>.  Trying to delete all
+non-push URLs is an error.
++
+Note that the push URL and the fetch URL, even though they can
+be set differently, must still refer to the same place.  What you
+pushed to the push URL should be what you would see if you
+immediately fetched from the fetch URL.  If you are trying to
+fetch from one place (e.g. your upstream) and push to another (e.g.

 Configuration
 -------------
 
-When configuration variable `repack.UseDeltaBaseOffset` is set
-for the repository, the command passes `--delta-base-offset`
-option to `git-pack-objects`; this typically results in slightly
-smaller packs, but the generated packs are incompatible with
-versions of git older than (and including) v1.4.3; do not set
-the variable in a repository that older version of git needs to
-be able to read (this includes repositories from which packs can
-be copied out over http or rsync, and people who obtained packs
-that way can try to use older git with it).

+By default, the command passes `--delta-base-offset` option to

+version 1.4.4. If you need to share your repository with such ancient Git
+versions, either directly or via the dumb http or rsync protocol, then you
+need to set the configuration variable `repack.UseDeltaBaseOffset` to

+NAME
+----
+git-replace - Create, list, delete refs to replace objects
+
+SYNOPSIS
+--------
+[verse]
+'git replace' [-f] <object> <replacement>
+'git replace' [-f] --edit <object>
+'git replace' [-f] --graft <commit> [<parent>...]
+'git replace' -d <object>...
+'git replace' [--format=<format>] [-l [<pattern>]]
+
+DESCRIPTION
+-----------
+Adds a 'replace' reference in `refs/replace/` namespace.
+
+The name of the 'replace' reference is the SHA-1 of the object that is
+replaced. The content of the 'replace' reference is the SHA-1 of the
+replacement object.
+
+The replaced object and the replacement object must be of the same type.
+This restriction can be bypassed using `-f`.
+
+Unless `-f` is given, the 'replace' reference must not yet exist.
+
+There is no other restriction on the replaced and replacement objects.
+Merge commits can be replaced by non-merge commits and vice versa.
+
+Replacement references will be used by default by all Git commands
+except those doing reachability traversal (prune, pack transfer and
+fsck).
+
+It is possible to disable use of replacement references for any
+command using the `--no-replace-objects` option just after 'git'.
+
+For example if commit 'foo' has been replaced by commit 'bar':
+
+------------------------------------------------
+$ git --no-replace-objects cat-file commit foo
+------------------------------------------------
+
+shows information about commit 'foo', while:
+
+------------------------------------------------
+$ git cat-file commit foo
+------------------------------------------------
+
+shows information about commit 'bar'.
+
+The 'GIT_NO_REPLACE_OBJECTS' environment variable can be set to
+achieve the same effect as the `--no-replace-objects` option.
+
+OPTIONS
+-------
+-f::
+--force::
+	If an existing replace ref for the same object exists, it will
+	be overwritten (instead of failing).
+
+-d::
+--delete::
+	Delete existing replace refs for the given objects.
+
+--edit <object>::
+	Edit an object's content interactively. The existing content
+	for <object> is pretty-printed into a temporary file, an
+	editor is launched on the file, and the result is parsed to
+	create a new object of the same type as <object>. A
+	replacement ref is then created to replace <object> with the
+	newly created object. See linkgit:git-var[1] for details about
+	how the editor will be chosen.
+
+--raw::
+	When editing, provide the raw object contents rather than
+	pretty-printed ones. Currently this only affects trees, which
+	will be shown in their binary form. This is harder to work with,
+	but can help when repairing a tree that is so corrupted it
+	cannot be pretty-printed. Note that you may need to configure
+	your editor to cleanly read and write binary data.
+
+--graft <commit> [<parent>...]::
+	Create a graft commit. A new commit is created with the same
+	content as <commit> except that its parents will be
+	[<parent>...] instead of <commit>'s parents. A replacement ref
+	is then created to replace <commit> with the newly created
+	commit. See contrib/convert-grafts-to-replace-refs.sh for an
+	example script based on this option that can convert grafts to
+	replace refs.
+
+-l <pattern>::
+--list <pattern>::
+	List replace refs for objects that match the given pattern (or
+	all if no pattern is given).
+	Typing "git replace" without arguments, also lists all replace
+	refs.
+
+--format=<format>::
+	When listing, use the specified <format>, which can be one of
+	'short', 'medium' and 'long'. When omitted, the format
+	defaults to 'short'.
+
+FORMATS
+-------
+
+The following format are available:
+
+* 'short':
+	<replaced sha1>
+* 'medium':
+	<replaced sha1> -> <replacement sha1>
+* 'long':
+	<replaced sha1> (<replaced type>) -> <replacement sha1> (<replacement type>)
+
+CREATING REPLACEMENT OBJECTS
+----------------------------
+
+linkgit:git-filter-branch[1], linkgit:git-hash-object[1] and
+linkgit:git-rebase[1], among other git commands, can be used to create
+replacement objects from existing objects. The `--edit` option can
+also be used with 'git replace' to create a replacement object by
+editing an existing object.
+
+If you want to replace many blobs, trees or commits that are part of a
+string of commits, you may just want to create a replacement string of
+commits and then only replace the commit at the tip of the target
+string of commits with the commit at the tip of the replacement string
+of commits.
+
+BUGS
+----
+Comparing blobs or trees that have been replaced with those that
+replace them will not work properly. And using `git reset --hard` to
+go back to a replaced commit will move the branch to the replacement
+commit instead of the replaced commit.
+
+There may be other problems when using 'git rev-list' related to
+pending objects.

 DESCRIPTION
 -----------
 
-Summarizes the changes between two commits to the standard output, and includes

+Generate a request asking your upstream project to pull changes into
+their tree.  The request, printed to the standard output,
+begins with the branch description, summarizes

+
+The upstream project is expected to have the commit named by
+`<start>` and the output asks it to integrate the changes you made
+since that commit, up to the commit named by `<end>`, by visiting
+the repository named by `<url>`.

 OPTIONS
 -------
+-p::
+	Include patch text in the output.

 <start>::
-	Commit to start at.
+	Commit to start at.  This names a commit that is already in

-	Commit to send at; defaults to HEAD.
+	Commit to end at (defaults to HEAD).  This names the commit

+When the repository named by `<url>` has the commit at a tip of a
+ref that is different from the ref you have locally, you can use the
+`<local>:<remote>` syntax, to have its local name, a colon `:`, and
+its remote name.
+
+
+EXAMPLE
+-------
+

 SYNOPSIS

 [verse]
-'git-reset' [--mixed | --soft | --hard] [<commit>]
-'git-reset' [--mixed] <commit> [--] <paths>...
+'git reset' [-q] [<tree-ish>] [--] <paths>...

+'git reset' [--soft | --mixed [-N] | --hard | --merge | --keep] [-q] [<commit>]
 
 DESCRIPTION
 -----------
-Sets the current head to the specified commit and optionally resets the
-index and working tree to match.
+In the first and second form, copy entries from <tree-ish> to the index.
+In the third form, set the current branch head (HEAD) to <commit>, optionally
+modifying index and working tree to match.  The <tree-ish>/<commit> defaults
+to HEAD in all forms.
 
-This command is useful if you notice some small error in a recent
-commit (or set of commits) and want to redo that part without showing
-the undo in the history.
-
-If you want to undo a commit other than the latest on a branch,
-gitlink:git-revert[1] is your friend.
+'git reset' [-q] [<tree-ish>] [--] <paths>...::
+	This form resets the index entries for all <paths> to their
+	state at <tree-ish>.  (It does not affect the working tree or
+	the current branch.)
++
+This means that `git reset <paths>` is the opposite of `git add
+<paths>`.
++
+After running `git reset <paths>` to update the index entry, you can
+use linkgit:git-checkout[1] to check the contents out of the index to
+the working tree.
+Alternatively, using linkgit:git-checkout[1] and specifying a commit, you
+can copy the contents of a path out of a commit to the index and to the
+working tree in one go.
 
-The second form with 'paths' is used to revert selected paths in
-the index from a given commit, without moving HEAD.
+'git reset' (--patch | -p) [<tree-ish>] [--] [<paths>...]::
+	Interactively select hunks in the difference between the index
+	and <tree-ish> (defaults to HEAD).  The chosen hunks are applied
+	in reverse to the index.
++
+This means that `git reset -p` is the opposite of `git add -p`, i.e.
+you can use it to selectively reset hunks. See the ``Interactive Mode''
+section of linkgit:git-add[1] to learn how to operate the `--patch` mode.
 
+'git reset' [<mode>] [<commit>]::
+	This form resets the current branch head to <commit> and
+	possibly updates the index (resetting it to the tree of <commit>) and
+	the working tree depending on <mode>. If <mode> is omitted,
+	defaults to "--mixed". The <mode> must be one of the following:
++
+--
+--soft::
+	Does not touch the index file or the working tree at all (but
+	resets the head to <commit>, just like all modes do). This leaves
+	all your changed files "Changes to be committed", as 'git status'
+	would put it.
 
-OPTIONS
--------
 --mixed::
 	Resets the index but not the working tree (i.e., the changed files
 	are preserved but not marked for commit) and reports what has not
 	been updated. This is the default action.
-
---soft::
-	Does not touch the index file nor the working tree at all, but
-	requires them to be in a good order. This leaves all your changed
-	files "Added but not yet committed", as gitlink:git-status[1] would
-	put it.
++
+If `-N` is specified, removed paths are marked as intent-to-add (see
+linkgit:git-add[1]).
 
 --hard::
-	Matches the working tree and index to that of the tree being
-	switched to. Any changes to tracked files in the working tree
-	since <commit> are lost.
+	Resets the index and working tree. Any changes to tracked files in the
+	working tree since <commit> are discarded.
+
+--merge::
+	Resets the index and updates the files in the working tree that are
+	different between <commit> and HEAD, but keeps those which are
+	different between the index and working tree (i.e. which have changes
+	which have not been added).
+	If a file that is different between <commit> and the index has unstaged
+	changes, reset is aborted.
++
+In other words, --merge does something like a 'git read-tree -u -m <commit>',
+but carries forward unmerged index entries.
+
+--keep::
+	Resets index entries and updates files in the working tree that are
+	different between <commit> and HEAD.
+	If a file that is different between <commit> and HEAD has local changes,
+	reset is aborted.
+--

+If you want to undo a commit other than the latest on a branch,

+"reset --merge" is meant to be used when resetting out of a conflicted
+merge. Any mergy operation guarantees that the working tree file that is
+involved in the merge does not have local change wrt the index before
+it starts, and that it writes the result out to the working tree. So if
+we see some difference between the index and the target and also
+between the index and the working tree, then it means that we are not
+resetting out from a state that a mergy operation left after failing
+with a conflict. That is why we disallow --merge option in this case.

+"reset --keep" is meant to be used when removing some of the last
+commits in the current branch while keeping changes in the working

+want to remove and the changes in the working tree we want to keep,
+the reset is disallowed. That's why it is disallowed if there are both
+changes between the working tree and HEAD, and between HEAD and the
+target. To be safe, it is also disallowed when there are unmerged
+entries.

 DESCRIPTION
 -----------
 
-Lists commit objects in reverse chronological order starting at the
-given commit(s), taking ancestry relationship into account.  This is
-useful to produce human-readable log output.
+List commits that are reachable by following the `parent` links from the
+given commit(s), but exclude commits that are reachable from the one(s)
+given with a '{caret}' in front of them.  The output is given in reverse
+chronological order by default.
 
-Commits which are stated with a preceding '{caret}' cause listing to
-stop at that point. Their parents are implied. Thus the following
-command:
+You can think of this as a set operation.  Commits given on the command
+line form a set of commits that are reachable from any of them, and then
+commits reachable from any of the ones given with '{caret}' in front are
+subtracted from that set.  The remaining commits are what comes out in the
+command's output.  Various other options and paths parameters can be used
+to further limit the result.
+
+Thus, the following command:
 
 -----------------------------------------------------------------------
-	$ git-rev-list foo bar ^baz
+	$ git rev-list foo bar ^baz
 -----------------------------------------------------------------------
 
-means "list all the commits which are included in 'foo' and 'bar', but
-not in 'baz'".
+means "list all the commits which are reachable from 'foo' or 'bar', but
+not from 'baz'".
 
 A special notation "'<commit1>'..'<commit2>'" can be used as a
 short-hand for "{caret}'<commit1>' '<commit2>'". For example, either of
 the following may be used interchangeably:
 
 -----------------------------------------------------------------------
-	$ git-rev-list origin..HEAD
-	$ git-rev-list HEAD ^origin
+	$ git rev-list origin..HEAD
+	$ git rev-list HEAD ^origin
 -----------------------------------------------------------------------
 
 Another special notation is "'<commit1>'...'<commit2>'" which is useful

 OPTIONS
 -------
 
-Commit Formatting
-~~~~~~~~~~~~~~~~~
-
-Using these options, gitlink:git-rev-list[1] will act similar to the
-more specialized family of commit log tools: gitlink:git-log[1],
-gitlink:git-show[1], and gitlink:git-whatchanged[1]
+:git-rev-list: 1
+include::rev-list-options.txt[]
 
 include::pretty-formats.txt[]
 
---relative-date::
-
-	Show dates relative to the current time, e.g. "2 hours ago".
-	Only takes effect for dates shown in human-readable format, such
-	as when using "--pretty".
-
---header::
-
-	Print the contents of the commit in raw-format; each record is
-	separated with a NUL character.
-
---parents::
-
-	Print the parents of the commit.
-
-Diff Formatting
-~~~~~~~~~~~~~~~
-
-Below are listed options that control the formatting of diff output.
-Some of them are specific to gitlink:git-rev-list[1], however other diff
-options may be given. See gitlink:git-diff-files[1] for more options.
-
--c::
-
-	This flag changes the way a merge commit is displayed.  It shows
-	the differences from each of the parents to the merge result
-	simultaneously instead of showing pairwise diff between a parent
-	and the result one at a time. Furthermore, it lists only files
-	which were modified from all parents.
-
---cc::
-
-	This flag implies the '-c' options and further compresses the
-	patch output by omitting hunks that show differences from only
-	one parent, or show the same change from all but one parent for
-	an Octopus merge.
-
--r::
-
-	Show recursive diffs.
-
--t::
-
-	Show the tree objects in the diff output. This implies '-r'.
-
-Commit Limiting
-~~~~~~~~~~~~~~~
-
-Besides specifying a range of commits that should be listed using the
-special notations explained in the description, additional commit
-limiting may be applied.
-
---
-
--n 'number', --max-count='number'::
-
-	Limit the number of commits output.
-
---skip='number'::
-
-	Skip 'number' commits before starting to show the commit output.
-
---since='date', --after='date'::
-
-	Show commits more recent than a specific date.
-
---until='date', --before='date'::
-
-	Show commits older than a specific date.
-
---max-age='timestamp', --min-age='timestamp'::
-
-	Limit the commits output to specified time range.
-
---author='pattern', --committer='pattern'::
-
-	Limit the commits output to ones with author/committer
-	header lines that match the specified pattern.
-
---grep='pattern'::
-
-	Limit the commits output to ones with log message that
-	matches the specified pattern.
-
---remove-empty::
-
-	Stop when a given path disappears from the tree.
-
---no-merges::
-
-	Do not print commits with more than one parent.
-
---not::
-
-	Reverses the meaning of the '{caret}' prefix (or lack thereof)
-	for all following revision specifiers, up to the next '--not'.
-
---all::
-
-	Pretend as if all the refs in `$GIT_DIR/refs/` are listed on the
-	command line as '<commit>'.
-
---stdin::
-
-	In addition to the '<commit>' listed on the command
-	line, read them from the standard input.
-
--g, --walk-reflogs::
-
-	Instead of walking the commit ancestry chain, walk
-	reflog entries from the most recent one to older ones.
-	When this option is used you cannot specify commits to
-	exclude (that is, '{caret}commit', 'commit1..commit2',
-	nor 'commit1...commit2' notations cannot be used).
-+
-With '\--pretty' format other than oneline (for obvious reasons),
-this causes the output to have two extra lines of information
-taken from the reflog.  By default, 'commit@{Nth}' notation is
-used in the output.  When the starting commit is specified as
-'commit@{now}', output also uses 'commit@{timestamp}' notation
-instead.  Under '\--pretty=oneline', the commit message is
-prefixed with this information on the same line.
-
---merge::
-
-	After a failed merge, show refs that touch files having a
-	conflict and don't exist on all heads to merge.
-
---boundary::
-
-	Output uninteresting commits at the boundary, which are usually
-	not shown.
-
---dense, --sparse::
-
-When optional paths are given, the default behaviour ('--dense') is to
-only output commits that changes at least one of them, and also ignore
-merges that do not touch the given paths.
-
-Use the '--sparse' flag to makes the command output all eligible commits
-(still subject to count and age limitation), but apply merge
-simplification nevertheless.
-
---bisect::
-
-Limit output to the one commit object which is roughly halfway between
-the included and excluded commits. Thus, if
-
------------------------------------------------------------------------
-	$ git-rev-list --bisect foo ^bar ^baz
------------------------------------------------------------------------
-
-outputs 'midpoint', the output of the two commands
-
------------------------------------------------------------------------
-	$ git-rev-list foo ^midpoint
-	$ git-rev-list midpoint ^bar ^baz
------------------------------------------------------------------------
-
-would be of roughly the same length.  Finding the change which
-introduces a regression is thus reduced to a binary search: repeatedly
-generate and test new 'midpoint's until the commit chain is of length
-one.
-
---
-
-Commit Ordering
-~~~~~~~~~~~~~~~
-
-By default, the commits are shown in reverse chronological order.
-
---topo-order::
-
-	This option makes them appear in topological order (i.e.
-	descendant commits are shown before their parents).
-
---date-order::
-
-	This option is similar to '--topo-order' in the sense that no
-	parent comes before all of its children, but otherwise things
-	are still ordered in the commit timestamp order.
-
---reverse::
-
-	Output the commits in reverse order.
-
-Object Traversal
-~~~~~~~~~~~~~~~~
-
-These options are mostly targeted for packing of git repositories.
-
---objects::
-
-	Print the object IDs of any object referenced by the listed
-	commits.  'git-rev-list --objects foo ^bar' thus means "send me
-	all object IDs which I need to download if I have the commit
-	object 'bar', but not 'foo'".
-
---objects-edge::
-
-	Similar to '--objects', but also print the IDs of excluded
-	commits prefixed with a "-" character.  This is used by
-	gitlink:git-pack-objects[1] to build "thin" pack, which records
-	objects in deltified form based on objects contained in these
-	excluded commits to reduce network traffic.
-
---unpacked::
-
-	Only useful with '--objects'; print the object IDs that are not
-	in packs.

+	Use 'git rev-parse' in option parsing mode (see PARSEOPT section below).
+
+--sq-quote::
+	Use 'git rev-parse' in shell quoting mode (see SQ-QUOTE

+	mode does only quoting. Nothing else is done to command input.
+
+Options for --parseopt
+~~~~~~~~~~~~~~~~~~~~~~

+--keep-dashdash::
+	Only meaningful in `--parseopt` mode. Tells the option parser to echo
+	out the first `--` met instead of skipping it.

+--stop-at-non-option::
+	Only meaningful in `--parseopt` mode.  Lets the option parser stop at
+	the first non-option argument.  This can be used to parse sub-commands
+	that take options themselves.

+--stuck-long::
+	Only meaningful in `--parseopt` mode. Output the options in their
+	long form if available, and with their arguments stuck.

++
+This can be used to convert arguments to a command run in a subdirectory

++
+If you want to make sure that the output actually names an object in
+your object database and/or can be used as a specific type of object

+For example, `git rev-parse "$VAR^{commit}"` will make sure `$VAR`
+names an existing object that is a commit-ish (i.e. a commit, or an

+
+--resolve-git-dir <path>::
+	Check if <path> is a valid repository or a gitfile that
+	points at a valid repository, and print the location of the
+	repository.  If <path> is a gitfile then the resolved path
+	to the real repository is printed.
+
+--git-path <path>::
+	Resolve "$GIT_DIR/<path>" and takes other path relocation
+	variables such as $GIT_OBJECT_DIRECTORY,
+	$GIT_INDEX_FILE... into account. For example, if
+	$GIT_OBJECT_DIRECTORY is set to /foo/bar then "git rev-parse
+	--git-path objects/abc" returns /foo/bar/abc.
 
---remotes::
-	Show tag refs found in `$GIT_DIR/refs/remotes`.
+--show-cdup::
+	When the command is invoked from a subdirectory, show the

-SPECIFYING REVISIONS

-
-A revision parameter typically, but not necessarily, names a

-syntax.  Here are various ways to spell object names.  The
-ones listed near the end of this list are to name trees and

-  your repository whose object name starts with dae86e.
-
-* An output from `git-describe`; i.e. a closest tag, followed by a
-  dash, a `g`, and an abbreviated object name.
-
-* A symbolic ref name.  E.g. 'master' typically means the commit
-  object referenced by $GIT_DIR/refs/heads/master.  If you
-  happen to have both heads/master and tags/master, you can
-  explicitly say 'heads/master' to tell git which one you mean.
-  When ambiguous, a `<name>` is disambiguated by taking the
-  first match in the following rules:
-
-  . if `$GIT_DIR/<name>` exists, that is what you mean (this is usually
-    useful only for `HEAD`, `FETCH_HEAD` and `MERGE_HEAD`);
-
-  . otherwise, `$GIT_DIR/refs/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/tags/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/heads/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/remotes/<name>` if exists;
-
-  . otherwise, `$GIT_DIR/refs/remotes/<name>/HEAD` if exists.
-
-* A ref followed by the suffix '@' with a date specification
-  enclosed in a brace
-  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
-  second ago\}' or '\{1979-02-26 18:30:00\}') to specify the value
-  of the ref at a prior point in time.  This suffix may only be
-  used immediately following a ref name and the ref must have an
-  existing log ($GIT_DIR/logs/<ref>).
-
-* A ref followed by the suffix '@' with an ordinal specification
-  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') to specify
-  the n-th prior value of that ref.  For example 'master@\{1\}'
-  is the immediate prior value of 'master' while 'master@\{5\}'
-  is the 5th prior value of 'master'. This suffix may only be used
-  immediately following a ref name and the ref must have an existing
-  log ($GIT_DIR/logs/<ref>).
-
-* You can use the '@' construct with an empty ref part to get at a
-  reflog of the current branch. For example, if you are on the
-  branch 'blabla', then '@\{1\}' means the same as 'blabla@\{1\}'.
-
-* A suffix '{caret}' to a revision parameter means the first parent of
-  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
-  'rev{caret}'
-  is equivalent to 'rev{caret}1').  As a special rule,
-  'rev{caret}0' means the commit itself and is used when 'rev' is the
-  object name of a tag object that refers to a commit object.
-
-* A suffix '{tilde}<n>' to a revision parameter means the commit
-  object that is the <n>th generation grand-parent of the named
-  commit object, following only the first parent.  I.e. rev~3 is
-  equivalent to rev{caret}{caret}{caret} which is equivalent to
-  rev{caret}1{caret}1{caret}1.  See below for a illustration of
-  the usage of this form.
-
-* A suffix '{caret}' followed by an object type name enclosed in
-  brace pair (e.g. `v0.99.8{caret}\{commit\}`) means the object
-  could be a tag, and dereference the tag recursively until an
-  object of that type is found or the object cannot be
-  dereferenced anymore (in which case, barf).  `rev{caret}0`
-  introduced earlier is a short-hand for `rev{caret}\{commit\}`.
-
-* A suffix '{caret}' followed by an empty brace pair
-  (e.g. `v0.99.8{caret}\{\}`) means the object could be a tag,
-  and dereference the tag recursively until a non-tag object is
-  found.
-
-* A colon, followed by a slash, followed by a text: this names
-  a commit whose commit message starts with the specified text.
-  This name returns the youngest matching commit which is
-  reachable from any ref.  If the commit message starts with a
-  '!', you have to repeat that;  the special sequence ':/!',
-  followed by something else than '!' is reserved for now.
-
-* A suffix ':' followed by a path; this names the blob or tree
-  at the given path in the tree-ish object named by the part
-  before the colon.
-
-* A colon, optionally followed by a stage number (0 to 3) and a
-  colon, followed by a path; this names a blob object in the
-  index at the given path.  Missing stage number (and the colon
-  that follows it) names an stage 0 entry.
-
-Here is an illustration, by Jon Loeliger.  Both node B and C are
-a commit parents of commit node A.  Parent commits are ordered
-left-to-right.

-SPECIFYING RANGES
------------------
-
-History traversing commands such as `git-log` operate on a set
-of commits, not just a single commit.  To these commands,
-specifying a single revision with the notation described in the
-previous section means the set of commits reachable from that
-commit, following the commit ancestry chain.
-
-To exclude commits reachable from a commit, a prefix `{caret}`
-notation is used.  E.g. "`{caret}r1 r2`" means commits reachable
-from `r2` but exclude the ones reachable from `r1`.
-
-This set operation appears so often that there is a shorthand
-for it.  "`r1..r2`" is equivalent to "`{caret}r1 r2`".  It is
-the difference of two sets (subtract the set of commits
-reachable from `r1` from the set of commits reachable from
-`r2`).
-
-A similar notation "`r1\...r2`" is called symmetric difference
-of `r1` and `r2` and is defined as
-"`r1 r2 --not $(git-merge-base --all r1 r2)`".
-It it the set of commits that are reachable from either one of
-`r1` or `r2` but not from both.
-
-Two other shorthands for naming a set that is formed by a commit
-and its parent commits exists.  `r1{caret}@` notation means all
-parents of `r1`.  `r1{caret}!` includes commit `r1` but excludes
-its all parents.
-
-Here are a handful examples:
-
-   D                A B D
-   D F              A B C D F
-   ^A G             B D
-   ^A F             B C F
-   G...I            C D F G I
-   ^B G I           C D F G I
-   F^@              A B C
-   F^! H            D F H

+PARSEOPT
+--------
+
+In `--parseopt` mode, 'git rev-parse' helps massaging options to bring to shell
+scripts the same facilities C builtins have. It works as an option normalizer
+(e.g. splits single switches aggregate values), a bit like `getopt(1)` does.
+
+It takes on the standard input the specification of the options to parse and
+understand, and echoes on the standard output a string suitable for `sh(1)` `eval`
+to replace the arguments with normalized ones.  In case of error, it outputs
+usage on the standard error stream, and exits with code 129.
+
+Note: Make sure you quote the result when passing it to `eval`.  See
+below for an example.
+
+Input Format
+~~~~~~~~~~~~
+
+'git rev-parse --parseopt' input format is fully text based. It has two parts,
+separated by a line that contains only `--`. The lines before the separator
+(should be one or more) are used for the usage.
+The lines after the separator describe the options.
+
+Each line of options has this format:
+
+------------
+<opt-spec><flags>*<arg-hint>? SP+ help LF
+------------
+
+`<opt-spec>`::
+	its format is the short option character, then the long option name
+	separated by a comma. Both parts are not required, though at least one
+	is necessary. May not contain any of the `<flags>` characters.
+	`h,help`, `dry-run` and `f` are examples of correct `<opt-spec>`.
+
+`<flags>`::
+	`<flags>` are of `*`, `=`, `?` or `!`.
+	* Use `=` if the option takes an argument.
+
+	* Use `?` to mean that the option takes an optional argument. You
+	  probably want to use the `--stuck-long` mode to be able to
+	  unambiguously parse the optional argument.
+
+	* Use `*` to mean that this option should not be listed in the usage
+	  generated for the `-h` argument. It's shown for `--help-all` as
+	  documented in linkgit:gitcli[7].
+
+	* Use `!` to not make the corresponding negated long option available.
+
+`<arg-hint>`::
+	`<arg-hint>`, if specified, is used as a name of the argument in the
+	help output, for options that take arguments. `<arg-hint>` is
+	terminated by the first whitespace.  It is customary to use a
+	dash to separate words in a multi-word argument hint.
+
+The remainder of the line, after stripping the spaces, is used
+as the help associated to the option.
+
+Blank lines are ignored, and lines that don't match this specification are used
+as option group headers (start the line with a space to create such
+lines on purpose).
+
+Example
+~~~~~~~
+
+------------
+OPTS_SPEC="\
+some-command [options] <args>...
+
+some-command does foo and bar!
+--
+h,help    show the help
+
+foo       some nifty option --foo
+bar=      some cool option --bar with an argument
+baz=arg   another cool option --baz with a named argument
+qux?path  qux may take a path argument but has meaning by itself
+
+  An option group Header
+C?        option C with an optional argument"
+
+eval "$(echo "$OPTS_SPEC" | git rev-parse --parseopt -- "$@" || echo exit $?)"
+------------
+
+
+Usage text
+~~~~~~~~~~
+
+When `"$@"` is `-h` or `--help` in the above example, the following
+usage text would be shown:
+
+------------
+usage: some-command [options] <args>...
+
+    some-command does foo and bar!
+
+    -h, --help            show the help
+    --foo                 some nifty option --foo
+    --bar ...             some cool option --bar with an argument
+    --baz <arg>           another cool option --baz with a named argument
+    --qux[=<path>]        qux may take a path argument but has meaning by itself
+
+An option group Header
+    -C[...]               option C with an optional argument
+------------
+
+SQ-QUOTE
+--------
+
+In `--sq-quote` mode, 'git rev-parse' echoes on the standard output a
+single line suitable for `sh(1)` `eval`. This line is made by
+normalizing the arguments following `--sq-quote`. Nothing other than
+quoting the arguments is done.
+
+If you want command input to still be interpreted as usual by
+'git rev-parse' before the output is shell quoted, see the `--sq`
+option.
+
+Example
+~~~~~~~
+
+------------
+$ cat >your-git-script.sh <<\EOF
+#!/bin/sh
+args=$(git rev-parse --sq-quote "$@")   # quote user-supplied arguments
+command="git frotz -n24 $args"          # and use it inside a handcrafted
+					# command line
+eval "$command"
+EOF
+
+$ sh your-git-script.sh "a b'c"
+------------
+
+EXAMPLES
+--------
+
+* Print the object name of the current commit:
++
+------------
+$ git rev-parse --verify HEAD
+------------
+
+* Print the commit object name from the revision in the $REV shell variable:
++
+------------
+$ git rev-parse --verify $REV^{commit}
+------------
++
+This will error out if $REV is empty or not a valid revision.
+
+* Similar to above:
++
+------------
+$ git rev-parse --default master --verify $REV
+------------
++
+but if $REV is empty, the commit object name from master will be printed.

 DESCRIPTION
 -----------

+
+Given one or more existing commits, revert the changes that the
+related patches introduce, and record some new commits that record
+them.  This requires your working tree to be clean (no modifications
+from the HEAD commit).
+
+Note: 'git revert' is used to record some new commits to reverse the
+effect of some earlier commits (often only a faulty one).  If you want to
+throw away all uncommitted changes in your working directory, you
+should see linkgit:git-reset[1], particularly the '--hard' option.  If
+you want to extract specific files as they were in another commit, you
+should see linkgit:git-checkout[1], specifically the `git checkout
+<commit> -- <filename>` syntax.  Take care with these alternatives as
+both will discard uncommitted changes in your working directory.

 DESCRIPTION
 -----------
-Remove files from the working tree and from the index.  The
-files have to be identical to the tip of the branch, and no

+Remove files from the index, or from the working tree and the index.

+(There is no option to remove a file only from the working tree

+The files being removed have to be identical to the tip of the branch,
+and no updates to their contents can be staged in the index,

 DISCUSSION
 ----------
 
-The list of <file> given to the command can be exact pathnames,
-file glob patterns, or leading directory name.  The command
-removes only the paths that is known to git.  Giving the name of
-a file that you have not told git about does not remove that file.

+The <file> list given to the command can be exact pathnames,
+file glob patterns, or leading directory names.  The command
+removes only the paths that are known to Git.  Giving the name of
+a file that you have not told Git about does not remove that file.
+
+File globbing matches across directory boundaries.  Thus, given
+two directories `d` and `d2`, there is a difference between
+using `git rm 'd*'` and `git rm 'd/*'`, as the former will
+also remove all of directory `d2`.
+
+REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM
+--------------------------------------------------------
+There is no option for `git rm` to remove from the index only
+the paths that have disappeared from the filesystem. However,
+depending on the use case, there are several ways that can be
+done.
+
+Using ``git commit -a''
+~~~~~~~~~~~~~~~~~~~~~~~
+If you intend that your next commit should record all modifications
+of tracked files in the working tree and record all removals of
+files that have been removed from the working tree with `rm`
+(as opposed to `git rm`), use `git commit -a`, as it will
+automatically notice and record all removals.  You can also have a
+similar effect without committing by using `git add -u`.
+
+Using ``git add -A''
+~~~~~~~~~~~~~~~~~~~~
+When accepting a new code drop for a vendor branch, you probably
+want to record both the removal of paths and additions of new paths
+as well as modifications of existing paths.
+
+Typically you would first remove all tracked files from the working
+tree using this command:
+
+----------------
+git ls-files -z | xargs -0 rm -f
+----------------
+
+and then untar the new code in the working tree. Alternately
+you could 'rsync' the changes into the working tree.
+
+After that, the easiest way to record all removals, additions, and
+modifications in the working tree is:
+
+----------------
+git add -A
+----------------
+
+See linkgit:git-add[1].
+
+Other ways
+~~~~~~~~~~
+If all you really want to do is to remove from the index the files
+that are no longer present in the working tree (perhaps because
+your working tree is dirty so that you cannot use `git commit -a`),
+use the following command:
+
+----------------
+git diff --name-only --diff-filter=D -z | xargs -0 git rm --cached
+----------------
+
+SUBMODULES
+----------
+Only submodules using a gitfile (which means they were cloned
+with a Git version 1.7.8 or newer) will be removed from the work
+tree, as their repository lives inside the .git directory of the
+superproject. If a submodule (or one of those nested inside it)
+still uses a .git directory, `git rm` will fail - no matter if forced
+or not - to protect the submodule's history. If it exists the
+submodule.<name> section in the linkgit:gitmodules[5] file will also
+be removed and that file will be staged (unless --cached or -n are used).
+
+A submodule is considered up-to-date when the HEAD is the same as
+recorded in the index, no tracked files are modified and no untracked
+files that aren't ignored are present in the submodules work tree.
+Ignored files are deemed expendable and won't stop a submodule's work
+tree from being removed.
+
+If you only want to remove the local checkout of a submodule from your
+work tree without committing the removal,
+use linkgit:git-submodule[1] `deinit` instead.
 
 EXAMPLES
 --------

+----
+Each time a superproject update removes a populated submodule
+(e.g. when switching between commits before and after the removal) a
+stale submodule checkout will remain in the old location. Removing the
+old directory is only safe when it uses a gitfile, as otherwise the
+history of the submodule will be deleted too. This step will be
+obsolete when recursive submodule update has been implemented.

-git-runstatus - A helper for git-status and git-commit
-
-
-SYNOPSIS
---------
-'git-runstatus' [--color|--nocolor] [--amend] [--verbose] [--untracked]
-
-
-DESCRIPTION
------------
-Examines paths in the working tree that has changes unrecorded
-to the index file, and changes between the index file and the
-current HEAD commit.  The former paths are what you _could_
-commit by running 'git add' (or 'git rm' if you are deleting) before running 'git
-commit', and the latter paths are what you _would_ commit by
-running 'git commit'.
-
-If there is no path that is different between the index file and
-the current HEAD commit, the command exits with non-zero status.
-
-Note that this is _not_ the user level command you would want to
-run from the command line.  Use 'git-status' instead.
-
-
-OPTIONS
--------
---color::
-	Show colored status, highlighting modified file names.
-
---nocolor::
-	Turn off coloring.
-
---amend::
-	Show status based on HEAD^1, not HEAD, i.e. show what
-	'git-commit --amend' would do.
-
---verbose::
-	Show unified diff of all file changes.
-
---untracked::
-	Show files in untracked directories, too.  Without this
-	option only its name and a trailing slash are displayed
-	for each untracked directory.
-
-
-OUTPUT
-------
-The output from this command is designed to be used as a commit
-template comments, and all the output lines are prefixed with '#'.

 DESCRIPTION
 -----------
 Takes the patches given on the command line and emails them out.
+Patches can be specified as files, directories (which will send all
+files in the directory), or directly as a revision list.  In the
+last case, any format accepted by linkgit:git-format-patch[1] can
+be passed to git send-email.
 
-The header of the email is configurable by command line options.  If not
+The header of the email is configurable via command-line options.  If not
 specified on the command line, the user will be prompted with a ReadLine
 enabled interface to provide the necessary information.
 
+There are two formats accepted for patch files:
+
+1. mbox format files
++
+This is what linkgit:git-format-patch[1] generates.  Most headers and MIME
+formatting are ignored.
+
+2. The original format used by Greg Kroah-Hartman's 'send_lots_of_email.pl'
+script
++
+This format expects the first line of the file to contain the "Cc:" value
+and the "Subject:" of the message as the second line.
+
+
 OPTIONS
 -------
-The options available are:
 
---bcc::
-	Specify a "Bcc:" value for each email.
+Composing
+~~~~~~~~~
+
+--annotate::
+	Review and edit each patch you're about to send. Default is the value
+	of 'sendemail.annotate'. See the CONFIGURATION section for
+	'sendemail.multiEdit'.
+
+--bcc=<address>,...::
+	Specify a "Bcc:" value for each email. Default is the value of
+	'sendemail.bcc'.
 +
-The --bcc option must be repeated for each user you want on the bcc list.
+This option may be specified multiple times.
 
---cc::
+--cc=<address>,...::
 	Specify a starting "Cc:" value for each email.
+	Default is the value of 'sendemail.cc'.
++
+This option may be specified multiple times.
+
+--compose::
+	Invoke a text editor (see GIT_EDITOR in linkgit:git-var[1])
+	to edit an introductory message for the patch series.
++
+When '--compose' is used, git send-email will use the From, Subject, and
+In-Reply-To headers specified in the message. If the body of the message
+(what you type after the headers and a blank line) only contains blank
+(or Git: prefixed) lines, the summary won't be sent, but From, Subject,
+and In-Reply-To headers will be used unless they are removed.
++
+Missing From or In-Reply-To headers will be prompted for.
++
+See the CONFIGURATION section for 'sendemail.multiEdit'.
+
+--from=<address>::
+	Specify the sender of the emails.  If not specified on the command line,
+	the value of the 'sendemail.from' configuration option is used.  If
+	neither the command-line option nor 'sendemail.from' are set, then the
+	user will be prompted for the value.  The default for the prompt will be
+	the value of GIT_AUTHOR_IDENT, or GIT_COMMITTER_IDENT if that is not
+	set, as returned by "git var -l".
+
+--in-reply-to=<identifier>::
+	Make the first mail (or all the mails with `--no-thread`) appear as a
+	reply to the given Message-Id, which avoids breaking threads to
+	provide a new patch series.
+	The second and subsequent emails will be sent as replies according to
+	the `--[no]-chain-reply-to` setting.
++
+So for example when `--thread` and `--no-chain-reply-to` are specified, the
+second and subsequent patches will be replies to the first one like in the
+illustration below where `[PATCH v2 0/3]` is in reply to `[PATCH 0/2]`:
++
+  [PATCH 0/2] Here is what I did...
+    [PATCH 1/2] Clean up and tests
+    [PATCH 2/2] Implementation
+    [PATCH v2 0/3] Here is a reroll
+      [PATCH v2 1/3] Clean up
+      [PATCH v2 2/3] New tests
+      [PATCH v2 3/3] Implementation
++
+Only necessary if --compose is also set.  If --compose
+is not set, this will be prompted for.
+
+--subject=<string>::
+	Specify the initial subject of the email thread.
+	Only necessary if --compose is also set.  If --compose
+	is not set, this will be prompted for.
+
+--to=<address>,...::
+	Specify the primary recipient of the emails generated. Generally, this
+	will be the upstream maintainer of the project involved. Default is the
+	value of the 'sendemail.to' configuration value; if that is unspecified,
+	and --to-cmd is not specified, this will be prompted for.
 +
-The --cc option must be repeated for each user you want on the cc list.
+This option may be specified multiple times.
 
---chain-reply-to, --no-chain-reply-to::
+--8bit-encoding=<encoding>::
+	When encountering a non-ASCII message or subject that does not
+	declare its encoding, add headers/quoting to indicate it is
+	encoded in <encoding>.  Default is the value of the
+	'sendemail.assume8bitEncoding'; if that is unspecified, this
+	will be prompted for if any non-ASCII files are encountered.
++
+Note that no attempts whatsoever are made to validate the encoding.
+
+--compose-encoding=<encoding>::
+	Specify encoding of compose message. Default is the value of the
+	'sendemail.composeencoding'; if that is unspecified, UTF-8 is assumed.
+
+--transfer-encoding=(7bit|8bit|quoted-printable|base64)::
+	Specify the transfer encoding to be used to send the message over SMTP.
+	7bit will fail upon encountering a non-ASCII message.  quoted-printable
+	can be useful when the repository contains files that contain carriage
+	returns, but makes the raw patch email file (as saved from a MUA) much
+	harder to inspect manually.  base64 is even more fool proof, but also
+	even more opaque.  Default is the value of the 'sendemail.transferEncoding'
+	configuration value; if that is unspecified, git will use 8bit and not
+	add a Content-Transfer-Encoding header.
+
+--xmailer::
+--no-xmailer::
+	Add (or prevent adding) the "X-Mailer:" header.  By default,
+	the header is added, but it can be turned off by setting the
+	`sendemail.xmailer` configuration variable to `false`.
+
+Sending
+~~~~~~~
+
+--envelope-sender=<address>::
+	Specify the envelope sender used to send the emails.
+	This is useful if your default address is not the address that is
+	subscribed to a list. In order to use the 'From' address, set the
+	value to "auto". If you use the sendmail binary, you must have
+	suitable privileges for the -f parameter.  Default is the value of the
+	'sendemail.envelopeSender' configuration variable; if that is
+	unspecified, choosing the envelope sender is left to your MTA.
+
+--smtp-encryption=<encryption>::
+	Specify the encryption to use, either 'ssl' or 'tls'.  Any other
+	value reverts to plain SMTP.  Default is the value of
+	'sendemail.smtpEncryption'.
+
+--smtp-domain=<FQDN>::
+	Specifies the Fully Qualified Domain Name (FQDN) used in the
+	HELO/EHLO command to the SMTP server.  Some servers require the
+	FQDN to match your IP address.  If not set, git send-email attempts
+	to determine your FQDN automatically.  Default is the value of
+	'sendemail.smtpDomain'.
+
+--smtp-auth=<mechanisms>::
+	Whitespace-separated list of allowed SMTP-AUTH mechanisms. This setting
+	forces using only the listed mechanisms. Example:
++
+------
+$ git send-email --smtp-auth="PLAIN LOGIN GSSAPI" ...
+------
++
+If at least one of the specified mechanisms matches the ones advertised by the
+SMTP server and if it is supported by the utilized SASL library, the mechanism
+is used for authentication. If neither 'sendemail.smtpAuth' nor '--smtp-auth'
+is specified, all mechanisms supported by the SASL library can be used.
+
+--smtp-pass[=<password>]::
+	Password for SMTP-AUTH. The argument is optional: If no
+	argument is specified, then the empty string is used as
+	the password. Default is the value of 'sendemail.smtpPass',
+	however '--smtp-pass' always overrides this value.
++
+Furthermore, passwords need not be specified in configuration files
+or on the command line. If a username has been specified (with
+'--smtp-user' or a 'sendemail.smtpUser'), but no password has been
+specified (with '--smtp-pass' or 'sendemail.smtpPass'), then
+a password is obtained using 'git-credential'.
+
+--smtp-server=<host>::
+	If set, specifies the outgoing SMTP server to use (e.g.
+	`smtp.example.com` or a raw IP address).  Alternatively it can
+	specify a full pathname of a sendmail-like program instead;
+	the program must support the `-i` option.  Default value can
+	be specified by the 'sendemail.smtpServer' configuration
+	option; the built-in default is `/usr/sbin/sendmail` or
+	`/usr/lib/sendmail` if such program is available, or
+	`localhost` otherwise.
+
+--smtp-server-port=<port>::
+	Specifies a port different from the default port (SMTP
+	servers typically listen to smtp port 25, but may also listen to
+	submission port 587, or the common SSL smtp port 465);
+	symbolic port names (e.g. "submission" instead of 587)
+	are also accepted. The port can also be set with the
+	'sendemail.smtpServerPort' configuration variable.
+
+--smtp-server-option=<option>::
+	If set, specifies the outgoing SMTP server option to use.
+	Default value can be specified by the 'sendemail.smtpServerOption'
+	configuration option.
++
+The --smtp-server-option option must be repeated for each option you want
+to pass to the server. Likewise, different lines in the configuration files
+must be used for each option.
+
+--smtp-ssl::
+	Legacy alias for '--smtp-encryption ssl'.
+
+--smtp-ssl-cert-path::
+	Path to a store of trusted CA certificates for SMTP SSL/TLS
+	certificate validation (either a directory that has been processed
+	by 'c_rehash', or a single file containing one or more PEM format
+	certificates concatenated together: see verify(1) -CAfile and
+	-CApath for more information on these). Set it to an empty string
+	to disable certificate verification. Defaults to the value of the
+	'sendemail.smtpsslcertpath' configuration variable, if set, or the
+	backing SSL library's compiled-in default otherwise (which should
+	be the best choice on most platforms).
+
+--smtp-user=<user>::
+	Username for SMTP-AUTH. Default is the value of 'sendemail.smtpUser';
+	if a username is not specified (with '--smtp-user' or 'sendemail.smtpUser'),
+	then authentication is not attempted.
+
+--smtp-debug=0|1::
+	Enable (1) or disable (0) debug output. If enabled, SMTP
+	commands and replies will be printed. Useful to debug TLS
+	connection and authentication problems.
+
+Automating
+~~~~~~~~~~
+
+--to-cmd=<command>::
+	Specify a command to execute once per patch file which
+	should generate patch file specific "To:" entries.
+	Output of this command must be single email address per line.
+	Default is the value of 'sendemail.tocmd' configuration value.
+
+--cc-cmd=<command>::
+	Specify a command to execute once per patch file which
+	should generate patch file specific "Cc:" entries.
+	Output of this command must be single email address per line.
+	Default is the value of 'sendemail.ccCmd' configuration value.
+
+--[no-]chain-reply-to::
 	If this is set, each email will be sent as a reply to the previous
 	email sent.  If disabled with "--no-chain-reply-to", all emails after
 	the first will be sent as replies to the first email sent.  When using
 	this, it is recommended that the first file given be an overview of the
-	entire patch series.
-	Default is --chain-reply-to
+	entire patch series. Disabled by default, but the 'sendemail.chainReplyTo'
+	configuration variable can be used to enable it.
 
---compose::
-	Use $EDITOR to edit an introductory message for the
-	patch series.
-
---from::
-	Specify the sender of the emails.  This will default to
-	the value GIT_COMMITTER_IDENT, as returned by "git-var -l".
-	The user will still be prompted to confirm this entry.
-
---in-reply-to::
-	Specify the contents of the first In-Reply-To header.
-	Subsequent emails will refer to the previous email 
-	instead of this if --chain-reply-to is set (the default)
-	Only necessary if --compose is also set.  If --compose
-	is not set, this will be prompted for.
+--identity=<identity>::
+	A configuration identity. When given, causes values in the
+	'sendemail.<identity>' subsection to take precedence over
+	values in the 'sendemail' section. The default identity is
+	the value of 'sendemail.identity'.
+
+--[no-]signed-off-by-cc::
+	If this is set, add emails found in Signed-off-by: or Cc: lines to the
+	cc list. Default is the value of 'sendemail.signedoffbycc' configuration
+	value; if that is unspecified, default to --signed-off-by-cc.
+
+--[no-]cc-cover::
+	If this is set, emails found in Cc: headers in the first patch of
+	the series (typically the cover letter) are added to the cc list
+	for each email set. Default is the value of 'sendemail.cccover'
+	configuration value; if that is unspecified, default to --no-cc-cover.
+
+--[no-]to-cover::
+	If this is set, emails found in To: headers in the first patch of
+	the series (typically the cover letter) are added to the to list
+	for each email set. Default is the value of 'sendemail.tocover'
+	configuration value; if that is unspecified, default to --no-to-cover.
+
+--suppress-cc=<category>::
+	Specify an additional category of recipients to suppress the
+	auto-cc of:
++
+--
+- 'author' will avoid including the patch author
+- 'self' will avoid including the sender
+- 'cc' will avoid including anyone mentioned in Cc lines in the patch header
+  except for self (use 'self' for that).
+- 'bodycc' will avoid including anyone mentioned in Cc lines in the
+  patch body (commit message) except for self (use 'self' for that).
+- 'sob' will avoid including anyone mentioned in Signed-off-by lines except
+   for self (use 'self' for that).
+- 'cccmd' will avoid running the --cc-cmd.
+- 'body' is equivalent to 'sob' + 'bodycc'
+- 'all' will suppress all auto cc values.
+--
++
+Default is the value of 'sendemail.suppresscc' configuration value; if
+that is unspecified, default to 'self' if --suppress-from is
+specified, as well as 'body' if --no-signed-off-cc is specified.
+
+--[no-]suppress-from::
+	If this is set, do not add the From: address to the cc: list.
+	Default is the value of 'sendemail.suppressFrom' configuration
+	value; if that is unspecified, default to --no-suppress-from.
+
+--[no-]thread::
+	If this is set, the In-Reply-To and References headers will be
+	added to each email sent.  Whether each mail refers to the
+	previous email (`deep` threading per 'git format-patch'
+	wording) or to the first email (`shallow` threading) is
+	governed by "--[no-]chain-reply-to".
++
+If disabled with "--no-thread", those headers will not be added
+(unless specified with --in-reply-to).  Default is the value of the
+'sendemail.thread' configuration value; if that is unspecified,
+default to --thread.
++
+It is up to the user to ensure that no In-Reply-To header already
+exists when 'git send-email' is asked to add it (especially note that
+'git format-patch' can be configured to do the threading itself).
+Failure to do so may not produce the expected result in the
+recipient's MUA.
+
+
+Administering
+~~~~~~~~~~~~~
 
---no-signed-off-by-cc::
-	Do not add emails found in Signed-off-by: lines to the cc list.
+--confirm=<mode>::
+	Confirm just before sending:
++
+--
+- 'always' will always confirm before sending
+- 'never' will never confirm before sending
+- 'cc' will confirm before sending when send-email has automatically
+  added addresses from the patch to the Cc list
+- 'compose' will confirm before sending the first message when using --compose.
+- 'auto' is equivalent to 'cc' + 'compose'
+--
++
+Default is the value of 'sendemail.confirm' configuration value; if that
+is unspecified, default to 'auto' unless any of the suppress options
+have been specified, in which case default to 'compose'.
+
+--dry-run::
+	Do everything except actually send the emails.
+
+--[no-]format-patch::
+	When an argument may be understood either as a reference or as a file name,
+	choose to understand it as a format-patch argument ('--format-patch')
+	or as a file name ('--no-format-patch'). By default, when such a conflict
+	occurs, git send-email will fail.
 
 --quiet::
 	Make git-send-email less verbose.  One line per email should be
 	all that is output.
 
---smtp-server::
-	If set, specifies the outgoing SMTP server to use.  A full
-	pathname of a sendmail-like program can be specified instead;
-	the program must support the `-i` option.  Default value can
-	be specified by the 'sendemail.smtpserver' configuration
-	option; the built-in default is `/usr/sbin/sendmail` or
-	`/usr/lib/sendmail` if such program is available, or
-	`localhost` otherwise.
+--[no-]validate::
+	Perform sanity checks on patches.
+	Currently, validation means the following:
++
+--
+		*	Warn of patches that contain lines longer than 998 characters; this
+			is due to SMTP limits as described by http://www.ietf.org/rfc/rfc2821.txt.
+--
++
+Default is the value of 'sendemail.validate'; if this is not set,
+default to '--validate'.
 
---subject::
-   	Specify the initial subject of the email thread.
-	Only necessary if --compose is also set.  If --compose
-	is not set, this will be prompted for.
+--force::
+	Send emails even if safety checks would prevent it.
 
---suppress-from::
-	Do not add the From: address to the cc: list, if it shows up in a From:
-	line.
 
---to::
-	Specify the primary recipient of the emails generated.
-	Generally, this will be the upstream maintainer of the
-	project involved.
+CONFIGURATION
+-------------
+
+sendemail.aliasesFile::
+	To avoid typing long email addresses, point this to one or more
+	email aliases files.  You must also supply 'sendemail.aliasFileType'.
+
+sendemail.aliasFileType::
+	Format of the file(s) specified in sendemail.aliasesFile. Must be
+	one of 'mutt', 'mailrc', 'pine', 'elm', or 'gnus', or 'sendmail'.
++
+What an alias file in each format looks like can be found in
+the documentation of the email program of the same name. The
+differences and limitations from the standard formats are
+described below:
 +
-The --to option must be repeated for each user you want on the to list.
+--
+sendmail;;
+*	Quoted aliases and quoted addresses are not supported: lines that
+	contain a `"` symbol are ignored.
+*	Redirection to a file (`/path/name`) or pipe (`|command`) is not
+	supported.
+*	File inclusion (`:include: /path/name`) is not supported.
+*	Warnings are printed on the standard error output for any
+	explicitly unsupported constructs, and any other lines that are not
+	recognized by the parser.
+--
 
+sendemail.multiEdit::
+	If true (default), a single editor instance will be spawned to edit
+	files you have to edit (patches when '--annotate' is used, and the
+	summary when '--compose' is used). If false, files will be edited one
+	after the other, spawning a new editor each time.

-Written by Ryan Anderson <ryan@michonline.com>
+sendemail.confirm::
+	Sets the default for whether to confirm before sending. Must be
+	one of 'always', 'never', 'cc', 'compose', or 'auto'. See '--confirm'
+	in the previous section for the meaning of these values.

 SYNOPSIS
 --------
-'git-shell' -c <command> <argument>
+[verse]
+'chsh' -s $(command -v git-shell) <user>
+'git clone' <user>`@localhost:/path/to/repo.git`
+'ssh' <user>`@localhost`
 
 DESCRIPTION
 -----------
-This is meant to be used as a login shell for SSH accounts you want
-to restrict to GIT pull/push access only. It permits execution only
-of server-side GIT commands implementing the pull/push functionality.
-The commands can be executed only by the '-c' option; the shell is not
-interactive.
 
-Currently, only the `git-receive-pack` and `git-upload-pack` commands
-are permitted to be called, with a single required argument.
+This is a login shell for SSH accounts to provide restricted Git access.
+It permits execution only of server-side Git commands implementing the
+pull/push functionality, plus custom commands present in a subdirectory
+named `git-shell-commands` in the user's home directory.
 
-Author
-------
-Written by Linus Torvalds <torvalds@osdl.org>
+COMMANDS
+--------
+
+'git shell' accepts the following commands after the '-c' option:
+
+'git receive-pack <argument>'::
+'git upload-pack <argument>'::
+'git upload-archive <argument>'::
+	Call the corresponding server-side command to support
+	the client's 'git push', 'git fetch', or 'git archive --remote'
+	request.
+'cvs server'::
+	Imitate a CVS server.  See linkgit:git-cvsserver[1].
+
+If a `~/git-shell-commands` directory is present, 'git shell' will
+also handle other, custom commands by running
+"`git-shell-commands/<command> <arguments>`" from the user's home
+directory.
+
+INTERACTIVE USE
+---------------
+
+By default, the commands above can be executed only with the '-c'
+option; the shell is not interactive.
+
+If a `~/git-shell-commands` directory is present, 'git shell'
+can also be run interactively (with no arguments).  If a `help`
+command is present in the `git-shell-commands` directory, it is
+run to provide the user with an overview of allowed actions.  Then a
+"git> " prompt is presented at which one can enter any of the
+commands from the `git-shell-commands` directory, or `exit` to close
+the connection.
 
-Documentation
---------------
-Documentation by Petr Baudis and the git-list <git@vger.kernel.org>.
+Generally this mode is used as an administrative interface to allow
+users to list repositories they have access to, create, delete, or
+rename repositories, or change repository descriptions and
+permissions.
+
+If a `no-interactive-login` command exists, then it is run and the
+interactive shell is aborted.
+
+EXAMPLE
+-------
+
+To disable interactive logins, displaying a greeting instead:
+
+----------------
+$ chsh -s /usr/bin/git-shell
+$ mkdir $HOME/git-shell-commands
+$ cat >$HOME/git-shell-commands/no-interactive-login <<\EOF
+#!/bin/sh
+printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
+printf '%s\n' "provide interactive shell access."

+
+DESCRIPTION
+-----------
+
+Use `git stash` when you want to record the current state of the
+working directory and the index, but want to go back to a clean
+working directory.  The command saves your local modifications away
+and reverts the working directory to match the `HEAD` commit.
+
+The modifications stashed away by this command can be listed with
+`git stash list`, inspected with `git stash show`, and restored
+(potentially on top of a different commit) with `git stash apply`.
+Calling `git stash` without any arguments is equivalent to `git stash save`.
+A stash is by default listed as "WIP on 'branchname' ...", but
+you can give a more descriptive message on the command line when
+you create one.
+
+The latest stash you created is stored in `refs/stash`; older
+stashes are found in the reflog of this reference and can be named using
+the usual reflog syntax (e.g. `stash@{0}` is the most recently
+created stash, `stash@{1}` is the one before it, `stash@{2.hours.ago}`
+is also possible).
+
+OPTIONS
+-------
+
+save [-p|--patch] [-k|--[no-]keep-index] [-u|--include-untracked] [-a|--all] [-q|--quiet] [<message>]::
+
+	Save your local modifications to a new 'stash', and run `git reset
+	--hard` to revert them.  The <message> part is optional and gives
+	the description along with the stashed state.  For quickly making
+	a snapshot, you can omit _both_ "save" and <message>, but giving
+	only <message> does not trigger this action to prevent a misspelled
+	subcommand from making an unwanted stash.
++
+If the `--keep-index` option is used, all changes already added to the
+index are left intact.
++
+If the `--include-untracked` option is used, all untracked files are also
+stashed and then cleaned up with `git clean`, leaving the working directory
+in a very clean state. If the `--all` option is used instead then the
+ignored files are stashed and cleaned in addition to the untracked files.
++
+With `--patch`, you can interactively select hunks from the diff
+between HEAD and the working tree to be stashed.  The stash entry is
+constructed such that its index state is the same as the index state
+of your repository, and its worktree contains only the changes you
+selected interactively.  The selected changes are then rolled back
+from your worktree. See the ``Interactive Mode'' section of
+linkgit:git-add[1] to learn how to operate the `--patch` mode.
++
+The `--patch` option implies `--keep-index`.  You can use
+`--no-keep-index` to override this.
+
+list [<options>]::
+
+	List the stashes that you currently have.  Each 'stash' is listed
+	with its name (e.g. `stash@{0}` is the latest stash, `stash@{1}` is
+	the one before, etc.), the name of the branch that was current when the
+	stash was made, and a short description of the commit the stash was
+	based on.
++
+----------------------------------------------------------------
+stash@{0}: WIP on submit: 6ebd0e2... Update git-stash documentation
+stash@{1}: On master: 9cc0589... Add git-stash
+----------------------------------------------------------------
++
+The command takes options applicable to the 'git log'
+command to control what is shown and how. See linkgit:git-log[1].
+
+show [<stash>]::
+
+	Show the changes recorded in the stash as a diff between the
+	stashed state and its original parent. When no `<stash>` is given,
+	shows the latest one. By default, the command shows the diffstat, but
+	it will accept any format known to 'git diff' (e.g., `git stash show
+	-p stash@{1}` to view the second most recent stash in patch form).
+
+pop [--index] [-q|--quiet] [<stash>]::
+
+	Remove a single stashed state from the stash list and apply it
+	on top of the current working tree state, i.e., do the inverse
+	operation of `git stash save`. The working directory must
+	match the index.
++
+Applying the state can fail with conflicts; in this case, it is not
+removed from the stash list. You need to resolve the conflicts by hand
+and call `git stash drop` manually afterwards.
++
+If the `--index` option is used, then tries to reinstate not only the working
+tree's changes, but also the index's ones. However, this can fail, when you
+have conflicts (which are stored in the index, where you therefore can no
+longer apply the changes as they were originally).
++
+When no `<stash>` is given, `stash@{0}` is assumed, otherwise `<stash>` must
+be a reference of the form `stash@{<revision>}`.
+
+apply [--index] [-q|--quiet] [<stash>]::
+
+	Like `pop`, but do not remove the state from the stash list. Unlike `pop`,
+	`<stash>` may be any commit that looks like a commit created by
+	`stash save` or `stash create`.
+
+branch <branchname> [<stash>]::
+
+	Creates and checks out a new branch named `<branchname>` starting from
+	the commit at which the `<stash>` was originally created, applies the
+	changes recorded in `<stash>` to the new working tree and index.
+	If that succeeds, and `<stash>` is a reference of the form
+	`stash@{<revision>}`, it then drops the `<stash>`. When no `<stash>`
+	is given, applies the latest one.
++
+This is useful if the branch on which you ran `git stash save` has
+changed enough that `git stash apply` fails due to conflicts. Since
+the stash is applied on top of the commit that was HEAD at the time
+`git stash` was run, it restores the originally stashed state with
+no conflicts.
+
+clear::
+	Remove all the stashed states. Note that those states will then
+	be subject to pruning, and may be impossible to recover (see
+	'Examples' below for a possible strategy).
+
+drop [-q|--quiet] [<stash>]::
+
+	Remove a single stashed state from the stash list. When no `<stash>`
+	is given, it removes the latest one. i.e. `stash@{0}`, otherwise
+	`<stash>` must be a valid stash log reference of the form
+	`stash@{<revision>}`.
+
+create::
+
+	Create a stash (which is a regular commit object) and return its
+	object name, without storing it anywhere in the ref namespace.
+	This is intended to be useful for scripts.  It is probably not
+	the command you want to use; see "save" above.
+
+store::
+
+	Store a given stash created via 'git stash create' (which is a
+	dangling merge commit) in the stash ref, updating the stash
+	reflog.  This is intended to be useful for scripts.  It is
+	probably not the command you want to use; see "save" above.
+
+DISCUSSION
+----------
+
+A stash is represented as a commit whose tree records the state of the
+working directory, and its first parent is the commit at `HEAD` when
+the stash was created.  The tree of the second parent records the
+state of the index when the stash is made, and it is made a child of
+the `HEAD` commit.  The ancestry graph looks like this:
+
+            .----W
+           /    /
+     -----H----I
+
+where `H` is the `HEAD` commit, `I` is a commit that records the state
+of the index, and `W` is a commit that records the state of the working
+tree.
+
+
+EXAMPLES
+--------
+
+Pulling into a dirty tree::
+
+When you are in the middle of something, you learn that there are
+upstream changes that are possibly relevant to what you are
+doing.  When your local changes do not conflict with the changes in
+the upstream, a simple `git pull` will let you move forward.
++
+However, there are cases in which your local changes do conflict with
+the upstream changes, and `git pull` refuses to overwrite your
+changes.  In such a case, you can stash your changes away,
+perform a pull, and then unstash, like this:
++
+----------------------------------------------------------------
+$ git pull
+ ...
+file foobar not up to date, cannot merge.
+$ git stash
+$ git pull
+$ git stash pop
+----------------------------------------------------------------
+
+Interrupted workflow::
+
+When you are in the middle of something, your boss comes in and
+demands that you fix something immediately.  Traditionally, you would
+make a commit to a temporary branch to store your changes away, and
+return to your original branch to make the emergency fix, like this:
++
+----------------------------------------------------------------
+# ... hack hack hack ...
+$ git checkout -b my_wip
+$ git commit -a -m "WIP"
+$ git checkout master
+$ edit emergency fix
+$ git commit -a -m "Fix in a hurry"
+$ git checkout my_wip
+$ git reset --soft HEAD^
+# ... continue hacking ...
+----------------------------------------------------------------
++
+You can use 'git stash' to simplify the above, like this:
++
+----------------------------------------------------------------
+# ... hack hack hack ...
+$ git stash
+$ edit emergency fix
+$ git commit -a -m "Fix in a hurry"
+$ git stash pop
+# ... continue hacking ...
+----------------------------------------------------------------
+
+Testing partial commits::
+
+You can use `git stash save --keep-index` when you want to make two or
+more commits out of the changes in the work tree, and you want to test
+each change before committing:
++
+----------------------------------------------------------------
+# ... hack hack hack ...
+$ git add --patch foo            # add just first part to the index
+$ git stash save --keep-index    # save all other changes to the stash
+$ edit/build/test first part
+$ git commit -m 'First part'     # commit fully tested change
+$ git stash pop                  # prepare to work on all other changes
+# ... repeat above five steps until one commit remains ...
+$ edit/build/test remaining parts
+$ git commit foo -m 'Remaining parts'
+----------------------------------------------------------------
+
+Recovering stashes that were cleared/dropped erroneously::
+
+If you mistakenly drop or clear stashes, they cannot be recovered
+through the normal safety mechanisms.  However, you can try the
+following incantation to get a list of stashes that are still in your
+repository, but not reachable any more:
++
+----------------------------------------------------------------
+git fsck --unreachable |
+grep commit | cut -d\  -f3 |
+xargs git log --merges --no-walk --grep=WIP

 DESCRIPTION
 -----------
-Examines paths in the working tree that has changes unrecorded
-to the index file, and changes between the index file and the

-commit by running 'git add' before running 'git
-commit', and the latter paths are what you _would_ commit by
-running 'git commit'.
-
-If there is no path that is different between the index file and

-status.
-
-The command takes the same set of options as `git-commit`; it
-shows what would be committed if the same options are given to
-`git-commit`.
+Displays paths that have differences between the index file and the

+are what you _would_ commit by running `git commit`; the second and
+third are what you _could_ commit by running 'git add' before running
+`git commit`.
+
+OPTIONS
+-------
+
+-s::
+--short::
+	Give the output in the short-format.
+
+-b::
+--branch::
+	Show the branch and tracking info even in short-format.
+
+--porcelain::
+	Give the output in an easy-to-parse format for scripts.
+	This is similar to the short output, but will remain stable
+	across Git versions and regardless of user configuration. See
+	below for details.
+
+--long::
+	Give the output in the long-format. This is the default.
+
+-v::
+--verbose::
+	In addition to the names of files that have been changed, also
+	show the textual changes that are staged to be committed
+	(i.e., like the output of `git diff --cached`). If `-v` is specified
+	twice, then also show the changes in the working tree that
+	have not yet been staged (i.e., like the output of `git diff`).
+
+-u[<mode>]::
+--untracked-files[=<mode>]::
+	Show untracked files.
++
+The mode parameter is used to specify the handling of untracked files.
+It is optional: it defaults to 'all', and if specified, it must be
+stuck to the option (e.g. `-uno`, but not `-u no`).
++
+The possible options are:
++
+	- 'no'     - Show no untracked files.
+	- 'normal' - Shows untracked files and directories.
+	- 'all'    - Also shows individual files in untracked directories.
++
+When `-u` option is not used, untracked files and directories are
+shown (i.e. the same as specifying `normal`), to help you avoid
+forgetting to add newly created files.  Because it takes extra work
+to find untracked files in the filesystem, this mode may take some
+time in a large working tree.
+Consider enabling untracked cache and split index if supported (see
+`git update-index --untracked-cache` and `git update-index
+--split-index`), Otherwise you can use `no` to have `git status`
+return more quickly without showing untracked files.
++
+The default can be changed using the status.showUntrackedFiles
+configuration variable documented in linkgit:git-config[1].
+
+--ignore-submodules[=<when>]::
+	Ignore changes to submodules when looking for changes. <when> can be
+	either "none", "untracked", "dirty" or "all", which is the default.
+	Using "none" will consider the submodule modified when it either contains
+	untracked or modified files or its HEAD differs from the commit recorded
+	in the superproject and can be used to override any settings of the
+	'ignore' option in linkgit:git-config[1] or linkgit:gitmodules[5]. When
+	"untracked" is used submodules are not considered dirty when they only
+	contain untracked content (but they are still scanned for modified
+	content). Using "dirty" ignores all changes to the work tree of submodules,
+	only changes to the commits stored in the superproject are shown (this was
+	the behavior before 1.7.0). Using "all" hides all changes to submodules
+	(and suppresses the output of submodule summaries when the config option
+	`status.submoduleSummary` is set).
+
+--ignored::
+	Show ignored files as well.
+
+-z::
+	Terminate entries with NUL, instead of LF.  This implies
+	the `--porcelain` output format if no other format is given.
+
+--column[=<options>]::
+--no-column::
+	Display untracked files in columns. See configuration variable
+	column.status for option syntax.`--column` and `--no-column`
+	without options are equivalent to 'always' and 'never'
+	respectively.
 
 
 OUTPUT
 ------
 The output from this command is designed to be used as a commit
-template comments, and all the output lines are prefixed with '#'.
-
+template comment.
+The default, long format, is designed to be human readable,
+verbose and descriptive.  Its contents and format are subject to change
+at any time.
+
+The paths mentioned in the output, unlike many other Git commands, are
+made relative to the current directory if you are working in a
+subdirectory (this is on purpose, to help cutting and pasting). See
+the status.relativePaths config option below.
+
+Short Format
+~~~~~~~~~~~~
+
+In the short-format, the status of each path is shown as
+
+	XY PATH1 -> PATH2
+
+where `PATH1` is the path in the `HEAD`, and the " `-> PATH2`" part is
+shown only when `PATH1` corresponds to a different path in the
+index/worktree (i.e. the file is renamed). The `XY` is a two-letter
+status code.
+
+The fields (including the `->`) are separated from each other by a
+single space. If a filename contains whitespace or other nonprintable
+characters, that field will be quoted in the manner of a C string
+literal: surrounded by ASCII double quote (34) characters, and with
+interior special characters backslash-escaped.
+
+For paths with merge conflicts, `X` and `Y` show the modification
+states of each side of the merge. For paths that do not have merge
+conflicts, `X` shows the status of the index, and `Y` shows the status
+of the work tree.  For untracked paths, `XY` are `??`.  Other status
+codes can be interpreted as follows:
+
+* ' ' = unmodified
+* 'M' = modified
+* 'A' = added
+* 'D' = deleted
+* 'R' = renamed
+* 'C' = copied
+* 'U' = updated but unmerged
+
+Ignored files are not listed, unless `--ignored` option is in effect,
+in which case `XY` are `!!`.
+
+    X          Y     Meaning
+    -------------------------------------------------
+              [MD]   not updated
+    M        [ MD]   updated in index
+    A        [ MD]   added to index
+    D         [ M]   deleted from index
+    R        [ MD]   renamed in index
+    C        [ MD]   copied in index
+    [MARC]           index and work tree matches
+    [ MARC]     M    work tree changed since index
+    [ MARC]     D    deleted in work tree
+    -------------------------------------------------
+    D           D    unmerged, both deleted
+    A           U    unmerged, added by us
+    U           D    unmerged, deleted by them
+    U           A    unmerged, added by them
+    D           U    unmerged, deleted by us
+    A           A    unmerged, both added
+    U           U    unmerged, both modified
+    -------------------------------------------------
+    ?           ?    untracked
+    !           !    ignored
+    -------------------------------------------------
+
+If -b is used the short-format status is preceded by a line
+
+## branchname tracking info
+
+Porcelain Format
+~~~~~~~~~~~~~~~~
+
+The porcelain format is similar to the short format, but is guaranteed
+not to change in a backwards-incompatible way between Git versions or
+based on user configuration. This makes it ideal for parsing by scripts.
+The description of the short format above also describes the porcelain
+format, with a few exceptions:
+
+1. The user's color.status configuration is not respected; color will
+   always be off.
+
+2. The user's status.relativePaths configuration is not respected; paths
+   shown will always be relative to the repository root.
+
+There is also an alternate -z format recommended for machine parsing. In
+that format, the status field is the same, but some other things
+change.  First, the '\->' is omitted from rename entries and the field
+order is reversed (e.g 'from \-> to' becomes 'to from'). Second, a NUL
+(ASCII 0) follows each filename, replacing space as a field separator
+and the terminating newline (but a space still separates the status
+field from the first filename).  Third, filenames containing special
+characters are not specially formatted; no quoting or
+backslash-escaping is performed.

+
+DESCRIPTION
+-----------
+Inspects, updates and manages submodules.
+
+A submodule allows you to keep another Git repository in a subdirectory
+of your repository. The other repository has its own history, which does not
+interfere with the history of the current repository. This can be used to
+have external dependencies such as third party libraries for example.
+
+When cloning or pulling a repository containing submodules however,
+these will not be checked out by default; the 'init' and 'update'
+subcommands will maintain submodules checked out and at
+appropriate revision in your working tree.
+
+Submodules are composed from a so-called `gitlink` tree entry
+in the main repository that refers to a particular commit object
+within the inner repository that is completely separate.
+A record in the `.gitmodules` (see linkgit:gitmodules[5]) file at the
+root of the source tree assigns a logical name to the submodule and
+describes the default URL the submodule shall be cloned from.
+The logical name can be used for overriding this URL within your
+local repository configuration (see 'submodule init').
+
+Submodules are not to be confused with remotes, which are other
+repositories of the same project; submodules are meant for
+different projects you would like to make part of your source tree,
+while the history of the two projects still stays completely
+independent and you cannot modify the contents of the submodule
+from within the main project.
+If you want to merge the project histories and want to treat the
+aggregated whole as a single project from then on, you may want to
+add a remote for the other project and use the 'subtree' merge strategy,
+instead of treating the other project as a submodule. Directories
+that come from both projects can be cloned and checked out as a whole
+if you choose to go that route.
+
+COMMANDS
+--------
+add::
+	Add the given repository as a submodule at the given path
+	to the changeset to be committed next to the current
+	project: the current project is termed the "superproject".
++
+This requires at least one argument: <repository>. The optional
+argument <path> is the relative location for the cloned submodule
+to exist in the superproject. If <path> is not given, the
+"humanish" part of the source repository is used ("repo" for
+"/path/to/repo.git" and "foo" for "host.xz:foo/.git").
+The <path> is also used as the submodule's logical name in its
+configuration entries unless `--name` is used to specify a logical name.
++
+<repository> is the URL of the new submodule's origin repository.
+This may be either an absolute URL, or (if it begins with ./
+or ../), the location relative to the superproject's origin
+repository (Please note that to specify a repository 'foo.git'
+which is located right next to a superproject 'bar.git', you'll
+have to use '../foo.git' instead of './foo.git' - as one might expect
+when following the rules for relative URLs - because the evaluation
+of relative URLs in Git is identical to that of relative directories).
+If the superproject doesn't have an origin configured
+the superproject is its own authoritative upstream and the current
+working directory is used instead.
++
+<path> is the relative location for the cloned submodule to
+exist in the superproject. If <path> does not exist, then the
+submodule is created by cloning from the named URL. If <path> does
+exist and is already a valid Git repository, then this is added
+to the changeset without cloning. This second form is provided
+to ease creating a new submodule from scratch, and presumes
+the user will later push the submodule to the given URL.
++
+In either case, the given URL is recorded into .gitmodules for
+use by subsequent users cloning the superproject. If the URL is
+given relative to the superproject's repository, the presumption
+is the superproject and submodule repositories will be kept
+together in the same relative location, and only the
+superproject's URL needs to be provided: git-submodule will correctly
+locate the submodule using the relative URL in .gitmodules.
+
+status::
+	Show the status of the submodules. This will print the SHA-1 of the
+	currently checked out commit for each submodule, along with the
+	submodule path and the output of 'git describe' for the
+	SHA-1. Each SHA-1 will be prefixed with `-` if the submodule is not
+	initialized, `+` if the currently checked out submodule commit
+	does not match the SHA-1 found in the index of the containing
+	repository and `U` if the submodule has merge conflicts.
++
+If `--recursive` is specified, this command will recurse into nested
+submodules, and show their status as well.
++
+If you are only interested in changes of the currently initialized
+submodules with respect to the commit recorded in the index or the HEAD,
+linkgit:git-status[1] and linkgit:git-diff[1] will provide that information
+too (and can also report changes to a submodule's work tree).
+
+init::
+	Initialize the submodules recorded in the index (which were
+	added and committed elsewhere) by copying submodule
+	names and urls from .gitmodules to .git/config.
+	Optional <path> arguments limit which submodules will be initialized.
+	It will also copy the value of `submodule.$name.update` into
+	.git/config.
+	The key used in .git/config is `submodule.$name.url`.
+	This command does not alter existing information in .git/config.
+	You can then customize the submodule clone URLs in .git/config
+	for your local setup and proceed to `git submodule update`;
+	you can also just use `git submodule update --init` without
+	the explicit 'init' step if you do not intend to customize
+	any submodule locations.
+
+deinit::
+	Unregister the given submodules, i.e. remove the whole
+	`submodule.$name` section from .git/config together with their work
+	tree. Further calls to `git submodule update`, `git submodule foreach`
+	and `git submodule sync` will skip any unregistered submodules until
+	they are initialized again, so use this command if you don't want to
+	have a local checkout of the submodule in your work tree anymore. If
+	you really want to remove a submodule from the repository and commit
+	that use linkgit:git-rm[1] instead.
++
+If `--force` is specified, the submodule's work tree will be removed even if
+it contains local modifications.
+
+update::
++
+--
+Update the registered submodules to match what the superproject
+expects by cloning missing submodules and updating the working tree of
+the submodules. The "updating" can be done in several ways depending
+on command line options and the value of `submodule.<name>.update`
+configuration variable. Supported update procedures are:
+
+	checkout;; the commit recorded in the superproject will be
+	    checked out in the submodule on a detached HEAD. This is
+	    done when `--checkout` option is given, or no option is
+	    given, and `submodule.<name>.update` is unset, or if it is
+	    set to 'checkout'.
++
+If `--force` is specified, the submodule will be checked out (using
+`git checkout --force` if appropriate), even if the commit specified
+in the index of the containing repository already matches the commit
+checked out in the submodule.
+
+	rebase;; the current branch of the submodule will be rebased
+	    onto the commit recorded in the superproject. This is done
+	    when `--rebase` option is given, or no option is given, and
+	    `submodule.<name>.update` is set to 'rebase'.
+
+	merge;; the commit recorded in the superproject will be merged
+	    into the current branch in the submodule. This is done
+	    when `--merge` option is given, or no option is given, and
+	    `submodule.<name>.update` is set to 'merge'.
+
+	custom command;; arbitrary shell command that takes a single
+	    argument (the sha1 of the commit recorded in the
+	    superproject) is executed. This is done when no option is
+	    given, and `submodule.<name>.update` has the form of
+	    '!command'.
+
+When no option is given and `submodule.<name>.update` is set to 'none',
+the submodule is not updated.
+
+If the submodule is not yet initialized, and you just want to use the
+setting as stored in .gitmodules, you can automatically initialize the
+submodule with the `--init` option.
+
+If `--recursive` is specified, this command will recurse into the
+registered submodules, and update any nested submodules within.
+--
+summary::
+	Show commit summary between the given commit (defaults to HEAD) and
+	working tree/index. For a submodule in question, a series of commits
+	in the submodule between the given super project commit and the
+	index or working tree (switched by `--cached`) are shown. If the option
+	`--files` is given, show the series of commits in the submodule between
+	the index of the super project and the working tree of the submodule
+	(this option doesn't allow to use the `--cached` option or to provide an
+	explicit commit).
++
+Using the `--submodule=log` option with linkgit:git-diff[1] will provide that
+information too.
+
+foreach::
+	Evaluates an arbitrary shell command in each checked out submodule.
+	The command has access to the variables $name, $path, $sha1 and
+	$toplevel:
+	$name is the name of the relevant submodule section in .gitmodules,
+	$path is the name of the submodule directory relative to the
+	superproject, $sha1 is the commit as recorded in the superproject,
+	and $toplevel is the absolute path to the top-level of the superproject.
+	Any submodules defined in the superproject but not checked out are
+	ignored by this command. Unless given `--quiet`, foreach prints the name
+	of each submodule before evaluating the command.
+	If `--recursive` is given, submodules are traversed recursively (i.e.
+	the given shell command is evaluated in nested submodules as well).
+	A non-zero return from the command in any submodule causes
+	the processing to terminate. This can be overridden by adding '|| :'
+	to the end of the command.
++
+As an example, +git submodule foreach \'echo $path {backtick}git
+rev-parse HEAD{backtick}'+ will show the path and currently checked out
+commit for each submodule.
+
+sync::
+	Synchronizes submodules' remote URL configuration setting
+	to the value specified in .gitmodules. It will only affect those
+	submodules which already have a URL entry in .git/config (that is the
+	case when they are initialized or freshly added). This is useful when
+	submodule URLs change upstream and you need to update your local
+	repositories accordingly.
++
+"git submodule sync" synchronizes all submodules while
+"git submodule sync \-- A" synchronizes submodule "A" only.
+
+OPTIONS
+-------
+-q::
+--quiet::
+	Only print error messages.
+
+-b::
+--branch::
+	Branch of repository to add as submodule.
+	The name of the branch is recorded as `submodule.<name>.branch` in
+	`.gitmodules` for `update --remote`.
+
+-f::
+--force::
+	This option is only valid for add, deinit and update commands.
+	When running add, allow adding an otherwise ignored submodule path.
+	When running deinit the submodule work trees will be removed even if
+	they contain local changes.
+	When running update (only effective with the checkout procedure),
+	throw away local changes in submodules when switching to a
+	different commit; and always run a checkout operation in the
+	submodule, even if the commit listed in the index of the
+	containing repository matches the commit checked out in the
+	submodule.
+
+--cached::
+	This option is only valid for status and summary commands.  These
+	commands typically use the commit found in the submodule HEAD, but
+	with this option, the commit stored in the index is used instead.
+
+--files::
+	This option is only valid for the summary command. This command
+	compares the commit in the index with that in the submodule HEAD
+	when this option is used.
+
+-n::
+--summary-limit::
+	This option is only valid for the summary command.
+	Limit the summary size (number of commits shown in total).
+	Giving 0 will disable the summary; a negative number means unlimited
+	(the default). This limit only applies to modified submodules. The
+	size is always limited to 1 for added/deleted/typechanged submodules.
+
+--remote::
+	This option is only valid for the update command.  Instead of using
+	the superproject's recorded SHA-1 to update the submodule, use the
+	status of the submodule's remote-tracking branch.  The remote used
+	is branch's remote (`branch.<name>.remote`), defaulting to `origin`.
+	The remote branch used defaults to `master`, but the branch name may
+	be overridden by setting the `submodule.<name>.branch` option in
+	either `.gitmodules` or `.git/config` (with `.git/config` taking
+	precedence).
++
+This works for any of the supported update procedures (`--checkout`,
+`--rebase`, etc.).  The only change is the source of the target SHA-1.
+For example, `submodule update --remote --merge` will merge upstream
+submodule changes into the submodules, while `submodule update
+--merge` will merge superproject gitlink changes into the submodules.
++
+In order to ensure a current tracking branch state, `update --remote`
+fetches the submodule's remote repository before calculating the
+SHA-1.  If you don't want to fetch, you should use `submodule update
+--remote --no-fetch`.
++

+`branch.<name>.merge`.  Prefer `submodule.<name>.branch` if you want
+to distribute the default upstream branch with the superproject and
+`branch.<name>.merge` if you want a more native feel while working in

 NAME

-git-svn - Bidirectional operation between a single Subversion branch and git
+git-svn - Bidirectional operation between a Subversion repository and Git
 
 SYNOPSIS
 --------
-'git-svn' <command> [options] [arguments]
+[verse]
+'git svn' <command> [options] [arguments]
 
 DESCRIPTION
 -----------
-git-svn is a simple conduit for changesets between Subversion and git.
-It is not to be confused with gitlink:git-svnimport[1], which is
-read-only.
+'git svn' is a simple conduit for changesets between Subversion and Git.
+It provides a bidirectional flow of changes between a Subversion and a Git
+repository.
 
-git-svn was originally designed for an individual developer who wants a
-bidirectional flow of changesets between a single branch in Subversion
-and an arbitrary number of branches in git.  Since its inception,
-git-svn has gained the ability to track multiple branches in a manner
-similar to git-svnimport.
+'git svn' can track a standard Subversion repository,
+following the common "trunk/branches/tags" layout, with the --stdlayout option.
+It can also follow branches and tags in any layout with the -T/-t/-b options
+(see options to 'init' below, and also the 'clone' command).
 
-git-svn is especially useful when it comes to tracking repositories
-not organized in the way Subversion developers recommend (trunk,
-branches, tags directories).
+Once tracking a Subversion repository (with any of the above methods), the Git
+repository can be updated from Subversion by the 'fetch' command and
+Subversion updated from Git by the 'dcommit' command.
 
 COMMANDS
 --------
---
 
 'init'::
-	Initializes an empty git repository with additional
-	metadata directories for git-svn.  The Subversion URL
+	Initializes an empty Git repository with additional
+	metadata directories for 'git svn'.  The Subversion URL
 	may be specified as a command-line argument, or as full
 	URL arguments to -T/-t/-b.  Optionally, the target
 	directory to operate on can be specified as a second
 	argument.  Normally this command initializes the current
 	directory.
 
--T<trunk_subdir>::
---trunk=<trunk_subdir>::
--t<tags_subdir>::
---tags=<tags_subdir>::
--b<branches_subdir>::
---branches=<branches_subdir>::
+-T<trunk_subdir>;;
+--trunk=<trunk_subdir>;;
+-t<tags_subdir>;;
+--tags=<tags_subdir>;;
+-b<branches_subdir>;;
+--branches=<branches_subdir>;;
+-s;;
+--stdlayout;;
 	These are optional command-line options for init.  Each of
 	these flags can point to a relative repository path
-	(--tags=project/tags') or a full url
-	(--tags=https://foo.org/project/tags)
-
---no-metadata::
+	(--tags=project/tags) or a full url
+	(--tags=https://foo.org/project/tags).
+	You can specify more than one --tags and/or --branches options, in case
+	your Subversion repository places tags or branches under multiple paths.
+	The option --stdlayout is
+	a shorthand way of setting trunk,tags,branches as the relative paths,
+	which is the Subversion default. If any of the other options are given
+	as well, they take precedence.
+--no-metadata;;
 	Set the 'noMetadata' option in the [svn-remote] config.
---use-svm-props::
+	This option is not recommended, please read the 'svn.noMetadata'
+	section of this manpage before using this option.
+--use-svm-props;;
 	Set the 'useSvmProps' option in the [svn-remote] config.
---use-svnsync-props::
+--use-svnsync-props;;
 	Set the 'useSvnsyncProps' option in the [svn-remote] config.
---rewrite-root=<URL>::
+--rewrite-root=<URL>;;
 	Set the 'rewriteRoot' option in the [svn-remote] config.
---username=<USER>::
+--rewrite-uuid=<UUID>;;
+	Set the 'rewriteUUID' option in the [svn-remote] config.
+--username=<user>;;
 	For transports that SVN handles authentication for (http,
 	https, and plain svn), specify the username.  For other
-	transports (eg svn+ssh://), you must include the username in
-	the URL, eg svn+ssh://foo@svn.bar.com/project
-
---prefix=<prefix>::
+	transports (e.g. `svn+ssh://`), you must include the username in
+	the URL, e.g. `svn+ssh://foo@svn.bar.com/project`
+--prefix=<prefix>;;
 	This allows one to specify a prefix which is prepended
 	to the names of remotes if trunk/branches/tags are
 	specified.  The prefix does not automatically include a
 	trailing slash, so be sure you include one in the
-	argument if that is what you want.  This is useful if
-	you wish to track multiple projects that share a common
+	argument if that is what you want.  If --branches/-b is
+	specified, the prefix must include a trailing slash.
+	Setting a prefix (with a trailing slash) is strongly
+	encouraged in any case, as your SVN-tracking refs will
+	then be located at "refs/remotes/$prefix/*", which is
+	compatible with Git's own remote-tracking ref layout
+	(refs/remotes/$remote/*). Setting a prefix is also useful
+	if you wish to track multiple projects that share a common
 	repository.
+	By default, the prefix is set to 'origin/'.
++
+NOTE: Before Git v2.0, the default prefix was "" (no prefix). This
+meant that SVN-tracking refs were put at "refs/remotes/*", which is
+incompatible with how Git's own remote-tracking refs are organized.
+If you still want the old default, you can get it by passing
+`--prefix ""` on the command line (`--prefix=""` may not work if
+your Perl's Getopt::Long is < v2.37).
+
+--ignore-paths=<regex>;;
+	When passed to 'init' or 'clone' this regular expression will
+	be preserved as a config key.  See 'fetch' for a description
+	of '--ignore-paths'.
+--include-paths=<regex>;;
+	When passed to 'init' or 'clone' this regular expression will
+	be preserved as a config key.  See 'fetch' for a description
+	of '--include-paths'.
+--no-minimize-url;;
+	When tracking multiple directories (using --stdlayout,
+	--branches, or --tags options), git svn will attempt to connect
+	to the root (or highest allowed level) of the Subversion
+	repository.  This default allows better tracking of history if
+	entire projects are moved within a repository, but may cause
+	issues on repositories where read access restrictions are in
+	place.  Passing '--no-minimize-url' will allow git svn to
+	accept URLs as-is without attempting to connect to a higher
+	level directory.  This option is off by default when only
+	one URL/branch is tracked (it would do little good).
 
 'fetch'::
-
 	Fetch unfetched revisions from the Subversion remote we are
 	tracking.  The name of the [svn-remote "..."] section in the
-	.git/config file may be specified as an optional command-line
-	argument.
+	$GIT_DIR/config file may be specified as an optional
+	command-line argument.
++
+This automatically updates the rev_map if needed (see
+'$GIT_DIR/svn/\*\*/.rev_map.*' in the FILES section below for details).
+
+--localtime;;
+	Store Git commit times in the local time zone instead of UTC.  This
+	makes 'git log' (even without --date=local) show the same times
+	that `svn log` would in the local time zone.
++
+This doesn't interfere with interoperating with the Subversion
+repository you cloned from, but if you wish for your local Git
+repository to be able to interoperate with someone else's local Git
+repository, either don't use this option or you should both use it in
+the same local time zone.
+
+--parent;;
+	Fetch only from the SVN parent of the current HEAD.
+
+--ignore-paths=<regex>;;
+	This allows one to specify a Perl regular expression that will
+	cause skipping of all matching paths from checkout from SVN.
+	The '--ignore-paths' option should match for every 'fetch'
+	(including automatic fetches due to 'clone', 'dcommit',
+	'rebase', etc) on a given repository.
++
+[verse]
+config key: svn-remote.<name>.ignore-paths
++
+If the ignore-paths configuration key is set, and the command-line
+option is also given, both regular expressions will be used.
++
+Examples:

+Skip "doc*" directory for every fetch;;

+--ignore-paths="^doc"
+------------------------------------------------------------------------
+

+--include-paths=<regex>;;

+	cause the inclusion of only matching paths from checkout from SVN.
+	The '--include-paths' option should match for every 'fetch'

 REBASE VS. PULL/MERGE
 ---------------------
+Prefer to use 'git svn rebase' or 'git rebase', rather than
+'git pull' or 'git merge' to synchronize unintegrated commits with a 'git svn'
+branch. Doing so will keep the history of unintegrated commits linear with
+respect to the upstream SVN repository and allow the use of the preferred
+'git svn dcommit' subcommand to push unintegrated commits back into SVN.
+
+Originally, 'git svn' recommended that developers pulled or merged from
+the 'git svn' branch.  This was because the author favored
+`git svn set-tree B` to commit a single head rather than the
+`git svn set-tree A..B` notation to commit multiple commits. Use of
+'git pull' or 'git merge' with `git svn set-tree A..B` will cause non-linear
+history to be flattened when committing into SVN and this can lead to merge
+commits unexpectedly reversing previous commits in SVN.
+
+MERGE TRACKING
+--------------
+While 'git svn' can track
+copy history (including branches and tags) for repositories adopting a
+standard layout, it cannot yet represent merge history that happened
+inside git back upstream to SVN users.  Therefore it is advised that
+users keep history as linear as possible inside Git to ease
+compatibility with SVN (see the CAVEATS section below).
+
+HANDLING OF SVN BRANCHES
+------------------------
+If 'git svn' is configured to fetch branches (and --follow-branches
+is in effect), it sometimes creates multiple Git branches for one
+SVN branch, where the additional branches have names of the form
+'branchname@nnn' (with nnn an SVN revision number).  These additional
+branches are created if 'git svn' cannot find a parent commit for the
+first commit in an SVN branch, to connect the branch to the history of
+the other branches.
+
+Normally, the first commit in an SVN branch consists
+of a copy operation. 'git svn' will read this commit to get the SVN
+revision the branch was created from. It will then try to find the
+Git commit that corresponds to this SVN revision, and use that as the
+parent of the branch. However, it is possible that there is no suitable
+Git commit to serve as parent.  This will happen, among other reasons,
+if the SVN branch is a copy of a revision that was not fetched by 'git
+svn' (e.g. because it is an old revision that was skipped with
+'--revision'), or if in SVN a directory was copied that is not tracked
+by 'git svn' (such as a branch that is not tracked at all, or a
+subdirectory of a tracked branch). In these cases, 'git svn' will still
+create a Git branch, but instead of using an existing Git commit as the
+parent of the branch, it will read the SVN history of the directory the
+branch was copied from and create appropriate Git commits.  This is
+indicated by the message "Initializing parent: <branchname>".
+
+Additionally, it will create a special branch named
+'<branchname>@<SVN-Revision>', where <SVN-Revision> is the SVN revision
+number the branch was copied from.  This branch will point to the newly
+created parent commit of the branch.  If in SVN the branch was deleted
+and later recreated from a different version, there will be multiple
+such branches with an '@'.
+
+Note that this may mean that multiple Git commits are created for a
+single SVN revision.
+
+An example: in an SVN repository with a standard
+trunk/tags/branches layout, a directory trunk/sub is created in r.100.
+In r.200, trunk/sub is branched by copying it to branches/. 'git svn
+clone -s' will then create a branch 'sub'. It will also create new Git
+commits for r.100 through r.199 and use these as the history of branch
+'sub'. Thus there will be two Git commits for each revision from r.100
+to r.199 (one containing trunk/, one containing trunk/sub/). Finally,
+it will create a branch 'sub@200' pointing to the new parent commit of
+branch 'sub' (i.e. the commit for r.200 and trunk/sub/).
+
+CAVEATS
+-------
 
-Originally, git-svn recommended that the remotes/git-svn branch be
-pulled or merged from.  This is because the author favored
-'git-svn set-tree B' to commit a single head rather than the
-'git-svn set-tree A..B' notation to commit multiple commits.
-
-If you use 'git-svn set-tree A..B' to commit several diffs and you do
-not have the latest remotes/git-svn merged into my-branch, you should
-use 'git-svn rebase' to update your work branch instead of 'git pull' or
-'git merge'.  'pull/merge' can cause non-linear history to be flattened
-when committing into SVN, which can lead to merge commits reversing
-previous commits in SVN.
-
-DESIGN PHILOSOPHY
------------------
-Merge tracking in Subversion is lacking and doing branched development
-with Subversion is cumbersome as a result.  git-svn does not do
-automated merge/branch tracking by default and leaves it entirely up to
-the user on the git side.  git-svn does however follow copy
-history of the directory that it is tracking, however (much like
-how 'svn log' works).
+For the sake of simplicity and interoperating with Subversion,
+it is recommended that all 'git svn' users clone, fetch and dcommit
+directly from the SVN server, and avoid all 'git clone'/'pull'/'merge'/'push'
+operations between Git repositories and branches.  The recommended
+method of exchanging code between Git branches and users is
+'git format-patch' and 'git am', or just 'dcommit'ing to the SVN repository.
+
+Running 'git merge' or 'git pull' is NOT recommended on a branch you
+plan to 'dcommit' from because Subversion users cannot see any
+merges you've made.  Furthermore, if you merge or pull from a Git branch
+that is a mirror of an SVN branch, 'dcommit' may commit to the wrong
+branch.
+
+If you do merge, note the following rule: 'git svn dcommit' will
+attempt to commit on top of the SVN commit named in
+------------------------------------------------------------------------
+git log --grep=^git-svn-id: --first-parent -1
+------------------------------------------------------------------------
+You 'must' therefore ensure that the most recent commit of the branch
+you want to dcommit to is the 'first' parent of the merge.  Chaos will
+ensue otherwise, especially if the first parent is an older commit on
+the same SVN branch.
+
+'git clone' does not clone branches under the refs/remotes/ hierarchy or
+any 'git svn' metadata, or config.  So repositories created and managed with
+using 'git svn' should use 'rsync' for cloning, if cloning is to be done
+at all.
+
+Since 'dcommit' uses rebase internally, any Git branches you 'git push' to
+before 'dcommit' on will require forcing an overwrite of the existing ref
+on the remote repository.  This is generally considered bad practice,
+see the linkgit:git-push[1] documentation for details.
+
+Do not use the --amend option of linkgit:git-commit[1] on a change you've
+already dcommitted.  It is considered bad practice to --amend commits
+you've already pushed to a remote repository for other users, and
+dcommit with SVN is analogous to that.
+
+When cloning an SVN repository, if none of the options for describing
+the repository layout is used (--trunk, --tags, --branches,
+--stdlayout), 'git svn clone' will create a Git repository with
+completely linear history, where branches and tags appear as separate
+directories in the working copy.  While this is the easiest way to get a
+copy of a complete repository, for projects with many branches it will
+lead to a working copy many times larger than just the trunk. Thus for
+projects using the standard directory structure (trunk/branches/tags),
+it is recommended to clone with option '--stdlayout'. If the project
+uses a non-standard structure, and/or if branches and tags are not
+required, it is easiest to only clone one directory (typically trunk),
+without giving any repository layout options.  If the full history with
+branches and tags is required, the options '--trunk' / '--branches' /
+'--tags' must be used.
+
+When using multiple --branches or --tags, 'git svn' does not automatically
+handle name collisions (for example, if two branches from different paths have
+the same name, or if a branch and a tag have the same name).  In these cases,
+use 'init' to set up your Git repository then, before your first 'fetch', edit
+the $GIT_DIR/config file so that the branches and tags are associated
+with different name spaces.  For example:
+
+	branches = stable/*:refs/remotes/svn/stable/*
+	branches = debug/*:refs/remotes/svn/debug/*

-DESCRIPTION
------------
-Imports a SVN repository into git. It will either create a new
-repository, or incrementally import into an existing one.
-
-SVN access is done by the SVN::Perl module.
-
-git-svnimport assumes that SVN repositories are organized into one
-"trunk" directory where the main development happens, "branch/FOO"
-directories for branches, and "/tags/FOO" directories for tags.
-Other subdirectories are ignored.
-
-git-svnimport creates a file ".git/svn2git", which is required for
-incremental SVN imports.
-
-OPTIONS
--------
--C <target-dir>::
-        The GIT repository to import to.  If the directory doesn't
-        exist, it will be created.  Default is the current directory.
-
--s <start_rev>::
-        Start importing at this SVN change number. The  default is 1.
-+
-When importing incrementally, you might need to edit the .git/svn2git file.
-
--i::
-	Import-only: don't perform a checkout after importing.  This option
-	ensures the working directory and index remain untouched and will
-	not create them if they do not exist.
-
--T <trunk_subdir>::
-	Name the SVN trunk. Default "trunk".
-
--t <tag_subdir>::
-	Name the SVN subdirectory for tags. Default "tags".
-
--b <branch_subdir>::
-	Name the SVN subdirectory for branches. Default "branches".
-
--o <branch-for-HEAD>::
-	The 'trunk' branch from SVN is imported to the 'origin' branch within
-	the git repository. Use this option if you want to import into a
-	different branch.
-
--r::
-	Prepend 'rX: ' to commit messages, where X is the imported
-	subversion revision.
-
--I <ignorefile_name>::
-	Import the svn:ignore directory property to files with this
-	name in each directory. (The Subversion and GIT ignore
-	syntaxes are similar enough that using the Subversion patterns
-	directly with "-I .gitignore" will almost always just work.)
-
--A <author_file>::
-	Read a file with lines on the form
-+
-------
-	username = User's Full Name <email@addr.es>
-
-------
-+
-and use "User's Full Name <email@addr.es>" as the GIT
-author and committer for Subversion commits made by
-"username". If encountering a commit made by a user not in the
-list, abort.
-+
-For convenience, this data is saved to $GIT_DIR/svn-authors
-each time the -A option is provided, and read from that same
-file each time git-svnimport is run with an existing GIT
-repository without -A.
-
--m::
-	Attempt to detect merges based on the commit message. This option
-	will enable default regexes that try to capture the name source
-	branch name from the commit message.
-
--M <regex>::
-	Attempt to detect merges based on the commit message with a custom
-	regex. It can be used with -m to also see the default regexes.
-	You must escape forward slashes.
-
--l <max_rev>::
-	Specify a maximum revision number to pull.
-+
-Formerly, this option controlled how many revisions to pull,
-due to SVN memory leaks. (These have been worked around.)
-
--R <repack_each_revs>::
-	Specify how often git repository should be repacked.
-+
-The default value is 1000. git-svnimport will do import in chunks of 1000
-revisions, after each chunk git repository will be repacked. To disable
-this behavior specify some big value here which is mote than number of
-revisions to import.
-
--P <path_from_trunk>::
-	Partial import of the SVN tree.
-+
-By default, the whole tree on the SVN trunk (/trunk) is imported.
-'-P my/proj' will import starting only from '/trunk/my/proj'.
-This option is useful when you want to import one project from a
-svn repo which hosts multiple projects under the same trunk.
-
--v::
-	Verbosity: let 'svnimport' report what it is doing.
-
--d::
-	Use direct HTTP requests if possible. The "<path>" argument is used
-	only for retrieving the SVN logs; the path to the contents is
-	included in the SVN log.
-
--D::
-	Use direct HTTP requests if possible. The "<path>" argument is used
-	for retrieving the logs, as well as for the contents.
-+
-There's no safe way to automatically find out which of these options to
-use, so you need to try both. Usually, the one that's wrong will die
-with a 40x error pretty quickly.
-
-<SVN_repository_URL>::
-	The URL of the SVN module you want to import. For local
-	repositories, use "file:///absolute/path".
-+
-If you're using the "-d" or "-D" option, this is the URL of the SVN
-repository itself; it usually ends in "/svn".
-
-<path>::
-	The path to the module you want to check out.
-
--h::
-	Print a short usage message and exit.
-
-OUTPUT
-------
-If '-v' is specified, the script reports what it is doing.
-
-Otherwise, success is indicated the Unix way, i.e. by simply exiting with
-a zero exit status.

+Tag objects (created with `-a`, `-s`, or `-u`) are called "annotated"

 OPTIONS
 -------
 -a::
+--annotate::
 	Make an unsigned, annotated tag object
 
 -s::
-	Make a GPG-signed tag, using the default e-mail address's key
+--sign::
+	Make a GPG-signed tag, using the default e-mail address's key.
 
--u <key-id>::
-	Make a GPG-signed tag, using the given key
+-u <keyid>::
+--local-user=<keyid>::
+	Make a GPG-signed tag, using the given key.
 
 -f::
+--force::
 	Replace an existing tag with the given name (instead of failing)
 
 -d::
+--delete::
 	Delete existing tags with the given names.
 
 -v::
-	Verify the gpg signature of given the tag
+--verify::
+	Verify the gpg signature of the given tag names.
+
+-n<num>::
+	<num> specifies how many lines from the annotation, if any,
+	are printed when using -l.
+	The default is not to print any annotation lines.
+	If no number is given to `-n`, only the first line is printed.
+	If the tag is not annotated, the commit message is displayed instead.
 
 -l <pattern>::
-	List tags that match the given pattern (or all if no pattern is given).
+--list <pattern>::
+	List tags with names that match the given pattern (or all if no
+	pattern is given).  Running "git tag" without arguments also
+	lists all tags. The pattern is a shell wildcard (i.e., matched
+	using fnmatch(3)).  Multiple patterns may be given; if any of
+	them matches, the tag is shown.
+
+--sort=<type>::
+	Sort in a specific order. Supported type is "refname"
+	(lexicographic order), "version:refname" or "v:refname" (tag
+	names are treated as versions). The "version:refname" sort
+	order can also be affected by the
+	"versionsort.prereleaseSuffix" configuration variable. Prepend
+	"-" to reverse sort order. When this option is not given, the
+	sort order defaults to the value configured for the 'tag.sort'
+	variable if it exists, or lexicographic order otherwise. See
+	linkgit:git-config[1].
+
+--column[=<options>]::
+--no-column::
+	Display tag listing in columns. See configuration variable
+	column.tag for option syntax.`--column` and `--no-column`
+	without options are equivalent to 'always' and 'never' respectively.

+
+--contains [<commit>]::
+	Only list tags which contain the specified commit (HEAD if not
+	specified).
+
+--points-at <object>::
+	Only list tags of the given object.
 
 -m <msg>::
-	Use the given tag message (instead of prompting)
+--message=<msg>::
+	Use the given tag message (instead of prompting).
+	If multiple `-m` options are given, their values are
+	concatenated as separate paragraphs.
+	Implies `-a` if none of `-a`, `-s`, or `-u <keyid>`
+	is given.
 
 -F <file>::
+--file=<file>::
 	Take the tag message from the given file.  Use '-' to
 	read the message from the standard input.
+	Implies `-a` if none of `-a`, `-s`, or `-u <keyid>`
+	is given.
+
+--cleanup=<mode>::
+	This option sets how the tag message is cleaned up.
+	The  '<mode>' can be one of 'verbatim', 'whitespace' and 'strip'.  The
+	'strip' mode is default. The 'verbatim' mode does not change message at
+	all, 'whitespace' removes just leading/trailing whitespace lines and
+	'strip' removes both whitespace and commentary.
+
+--create-reflog::
+	Create a reflog for the tag.
+
+<tagname>::
+	The name of the tag to create, delete, or describe.
+	The new tag name must pass all checks defined by
+	linkgit:git-check-ref-format[1].  Some of these checks
+	may restrict the characters allowed in a tag name.
+
+<commit>::
+<object>::
+	The object that the new tag will refer to, usually a commit.
+	Defaults to HEAD.

-git-tar-tree - Create a tar archive of the files in the named tree object
-
-
-SYNOPSIS
---------
-'git-tar-tree' [--remote=<repo>] <tree-ish> [ <base> ]
-
-DESCRIPTION
------------
-THIS COMMAND IS DEPRECATED.  Use `git-archive` with `--format=tar`
-option instead.
-
-Creates a tar archive containing the tree structure for the named tree.
-When <base> is specified it is added as a leading path to the files in the
-generated tar archive.
-
-git-tar-tree behaves differently when given a tree ID versus when given
-a commit ID or tag ID.  In the first case the current time is used as
-modification time of each file in the archive.  In the latter case the
-commit time as recorded in the referenced commit object is used instead.
-Additionally the commit ID is stored in a global extended pax header.
-It can be extracted using git-get-tar-commit-id.
-
-OPTIONS
--------
-
-<tree-ish>::
-	The tree or commit to produce tar archive for.  If it is
-	the object name of a commit object.
-
-<base>::
-	Leading path to the files in the resulting tar archive.
-
---remote=<repo>::
-	Instead of making a tar archive from local repository,
-	retrieve a tar archive from a remote repository.
-
-CONFIGURATION
--------------
-By default, file and directories modes are set to 0666 or 0777. It is
-possible to change this by setting the "umask" variable in the
-repository configuration as follows :
-
-[tar]
-        umask = 002	;# group friendly
-
-The special umask value "user" indicates that the user's current umask
-will be used instead.  The default value is 002, which means group
-readable/writable files and directories.
-
-EXAMPLES
---------
-git tar-tree HEAD junk | (cd /var/tmp/ && tar xf -)::
-
-	Create a tar archive that contains the contents of the
-	latest commit on the current branch, and extracts it in
-	`/var/tmp/junk` directory.
-
-git tar-tree v1.4.0 git-1.4.0 | gzip >git-1.4.0.tar.gz::
-
-	Create a tarball for v1.4.0 release.
-
-git tar-tree v1.4.0{caret}\{tree\} git-1.4.0 | gzip >git-1.4.0.tar.gz::
-
-	Create a tarball for v1.4.0 release, but without a
-	global extended pax header.
-
-git tar-tree --remote=example.com:git.git v1.4.0 >git-1.4.0.tar::
-
-	Get a tarball v1.4.0 from example.com.
-
-git tar-tree HEAD:Documentation/ git-docs > git-1.4.0-docs.tar::
-
-	Put everything in the current head's Documentation/ directory
-	into 'git-1.4.0-docs.tar', with the prefix 'git-docs/'.

-A short git tools survey
-========================
+Git Tools
+=========
 
+When Git was young, people looking for third-party Git-related tools came
+to the Git project itself to find them, thus a list of such tools was
+maintained here. These days, however, search engines fill that role much
+more efficiently, so this manually-maintained list has been retired.
 
-Introduction
-------------
-
-Apart from git contrib/ area there are some others third-party tools
-you may want to look.
-
-This document presents a brief summary of each tool and the corresponding
-link.
-
-
-Alternative/Augmentative Porcelains
------------------------------------
-
-   - *Cogito* (http://www.kernel.org/pub/software/scm/cogito/)
-
-   Cogito is a version control system layered on top of the git tree history
-   storage system. It aims at seamless user interface and ease of use,
-   providing generally smoother user experience than the "raw" Core GIT
-   itself and indeed many other version control systems.
-
-
-   - *pg* (http://www.spearce.org/category/projects/scm/pg/)
-
-   pg is a shell script wrapper around GIT to help the user manage a set of
-   patches to files. pg is somewhat like quilt or StGIT, but it does have a
-   slightly different feature set.
-
-
-   - *StGit* (http://www.procode.org/stgit/)
-
-   Stacked GIT provides a quilt-like patch management functionality in the
-    GIT environment. You can easily manage your patches in the scope of GIT
-   until they get merged upstream.
-
-
-History Viewers
----------------
-
-   - *gitk* (shipped with git-core)
-
-   gitk is a simple Tk GUI for browsing history of GIT repositories easily.
-
-
-   - *gitview*  (contrib/)
-
-   gitview is a GTK based repository browser for git
-
-
-   - *gitweb* (shipped with git-core)
-
-   GITweb provides full-fledged web interface for GIT repositories.
-
-
-   - *qgit* (http://digilander.libero.it/mcostalba/)
-
-   QGit is a git/StGIT GUI viewer built on Qt/C++. QGit could be used
-   to browse history and directory tree, view annotated files, commit
-   changes cherry picking single files or applying patches.
-   Currently it is the fastest and most feature rich among the git
-   viewers and commit tools.
-
-   - *tig* (http://jonas.nitro.dk/tig/)
-
-   tig by Jonas Fonseca is a simple git repository browser
-   written using ncurses. Basically, it just acts as a front-end
-   for git-log and git-show/git-diff. Additionally, you can also
-   use it as a pager for git commands.
-
-
-Foreign SCM interface
----------------------
-
-   - *git-svn* (shipped with git-core)
-
-   git-svn is a simple conduit for changesets between a single Subversion
-   branch and git.
-
-
-   - *quilt2git / git2quilt* (http://home-tj.org/wiki/index.php/Misc)
-
-   These utilities convert patch series in a quilt repository and commit
-   series in git back and forth.
-
-
-   - *hg-to-git* (contrib/)
-
-   hg-to-git converts a Mercurial repository into a git one, and
-   preserves the full branch history in the process. hg-to-git can
-   also be used in an incremental way to keep the git repository
-   in sync with the master Mercurial repository.
-
-
-Others
-------
-
-   - *(h)gct* (http://www.cyd.liu.se/users/~freku045/gct/)
-
-   Commit Tool or (h)gct is a GUI enabled commit tool for git and
-   Mercurial (hg). It allows the user to view diffs, select which files
-   to committed (or ignored / reverted) write commit messages and
-   perform the commit itself.
-
-   - *git.el* (contrib/)
-
-   This is an Emacs interface for git. The user interface is modeled on
-   pcl-cvs. It has been developed on Emacs 21 and will probably need some
-   tweaking to work on XEmacs.
-
-
-http://git.or.cz/gitwiki/InterfacesFrontendsAndTools has more
-comprehensive list.

+Skip-worktree bit
+-----------------
+
+Skip-worktree bit can be defined in one (long) sentence: When reading
+an entry, if it is marked as skip-worktree, then Git pretends its
+working directory version is up to date and read the index version
+instead.
+
+To elaborate, "reading" means checking for file existence, reading
+file attributes or file content. The working directory version may be
+present or absent. If present, its content may match against the index
+version or not. Writing is not affected by this bit, content safety
+is still first priority. Note that Git _can_ update working directory
+file, that is marked skip-worktree, if it is safe to do so (i.e.
+working directory version matches index version)
+
+Although this bit looks similar to assume-unchanged bit, its goal is
+different from assume-unchanged bit's. Skip-worktree also takes
+precedence over assume-unchanged bit when both are set.

 executable bit.   On such an unfortunate filesystem, you may

+SECURITY
+--------
+
+In order to protect the privacy of objects that have been removed from
+history but may not yet have been pruned, `git-upload-archive` avoids
+serving archives for commits and trees that are not reachable from the
+repository's refs.  However, because calculating object reachability is
+computationally expensive, `git-upload-archive` implements a stricter
+but easier-to-check set of rules:
+
+  1. Clients may request a commit or tree that is pointed to directly by
+     a ref. E.g., `git archive --remote=origin v1.0`.
+
+  2. Clients may request a sub-tree within a commit or tree using the
+     `ref:path` syntax. E.g., `git archive --remote=origin v1.0:Documentation`.
+
+  3. Clients may _not_ use other sha1 expressions, even if the end
+     result is reachable. E.g., neither a relative commit like `master^`
+     nor a literal sha1 like `abcd1234` is allowed, even if the result
+     is reachable from the refs.
+
+Note that rule 3 disallows many cases that do not have any privacy
+implications. These rules are subject to change in future versions of
+git, and the server accessed by `git archive --remote` may or may not
+follow these exact rules.
+
+If the config option `uploadArchive.allowUnreachable` is true, these
+rules are ignored, and clients may use arbitrary sha1 expressions.
+This is useful if you do not care about the privacy of unreachable
+objects, or if your object database is already publicly available for
+access via non-smart-http.

+'git web{litdd}browse' [OPTIONS] URL/FILE ...
+
+DESCRIPTION
+-----------
+
+This script tries, as much as possible, to display the URLs and FILEs
+that are passed as arguments, as HTML pages in new tabs on an already
+opened web browser.
+
+The following browsers (or commands) are currently supported:
+
+* firefox (this is the default under X Window when not using KDE)
+* iceweasel
+* seamonkey
+* iceape
+* chromium (also supported as chromium-browser)
+* google-chrome (also supported as chrome)
+* konqueror (this is the default under KDE, see 'Note about konqueror' below)
+* opera
+* w3m (this is the default outside graphical environments)
+* elinks
+* links
+* lynx
+* dillo
+* open (this is the default under Mac OS X GUI)
+* start (this is the default under MinGW)
+* cygstart (this is the default under Cygwin)
+* xdg-open
+
+Custom commands may also be specified.
+
+OPTIONS
+-------
+-b <browser>::
+--browser=<browser>::
+	Use the specified browser. It must be in the list of supported
+	browsers.
+
+-t <browser>::
+--tool=<browser>::
+	Same as above.
+
+-c <conf.var>::
+--config=<conf.var>::
+	CONF.VAR is looked up in the Git config files. If it's set,
+	then its value specifies the browser that should be used.
+
+CONFIGURATION VARIABLES
+-----------------------
+
+CONF.VAR (from -c option) and web.browser
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The web browser can be specified using a configuration variable passed
+with the -c (or --config) command-line option, or the 'web.browser'
+configuration variable if the former is not used.
+
+browser.<tool>.path
+~~~~~~~~~~~~~~~~~~~
+
+You can explicitly provide a full path to your preferred browser by
+setting the configuration variable 'browser.<tool>.path'. For example,
+you can configure the absolute path to firefox by setting
+'browser.firefox.path'. Otherwise, 'git web{litdd}browse' assumes the tool
+is available in PATH.
+
+browser.<tool>.cmd
+~~~~~~~~~~~~~~~~~~
+
+When the browser, specified by options or configuration variables, is
+not among the supported ones, then the corresponding
+'browser.<tool>.cmd' configuration variable will be looked up. If this
+variable exists then 'git web{litdd}browse' will treat the specified tool
+as a custom command and will use a shell eval to run the command with
+the URLs passed as arguments.
+
+Note about konqueror
+--------------------
+
+When 'konqueror' is specified by a command-line option or a
+configuration variable, we launch 'kfmclient' to try to open the HTML
+man page on an already opened konqueror in a new tab if possible.
+
+For consistency, we also try such a trick if 'browser.konqueror.path' is
+set to something like 'A_PATH_TO/konqueror'. That means we will try to
+launch 'A_PATH_TO/kfmclient' instead.
+
+If you really want to use 'konqueror', then you can use something like
+the following:
+
+------------------------------------------------
+	[web]
+		browser = konq
+
+	[browser "konq"]
+		cmd = A_PATH_TO/konqueror
+------------------------------------------------
+
+Note about git-config --global
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Note that these configuration variables should probably be set using
+the '--global' flag, for example like this:
+
+------------------------------------------------
+$ git config --global web.browser firefox
+------------------------------------------------
+
+as they are probably more user specific than repository specific.
+See linkgit:git-config[1] for more information about this.

 SYNOPSIS
 --------
-'git-whatchanged' <option>...
+[verse]
+'git whatchanged' <option>...
 
 DESCRIPTION
 -----------
-Shows commit logs and diff output each commit introduces.  The
-command internally invokes 'git-rev-list' piped to
-'git-diff-tree', and takes command line options for both of
-these commands.
 
-This manual page describes only the most frequently used options.
+Shows commit logs and diff output each commit introduces.
 
+New users are encouraged to use linkgit:git-log[1] instead.  The
+`whatchanged` command is essentially the same as linkgit:git-log[1]
+but defaults to show the raw format diff output and to skip merges.
 
-OPTIONS
--------
--p::
-	Show textual diffs, instead of the git internal diff
-	output format that is useful only to tell the changed
-	paths and their nature of changes.
+The command is kept primarily for historical reasons; fingers of
+many people who learned Git long before `git log` was invented by
+reading Linux kernel mailing list are trained to type it.
 
--<n>::
-	Limit output to <n> commits.
-
-<since>..<until>::
-	Limit output to between the two named commits (bottom
-	exclusive, top inclusive).
-
--r::
-	Show git internal diff output, but for the whole tree,
-	not just the top level.
-
---pretty=<format>::
-	Controls the output format for the commit logs.
-	<format> can be one of 'raw', 'medium', 'short', 'full',
-	and 'oneline'.
-
--m::
-	By default, differences for merge commits are not shown.
-	With this flag, show differences to that commit from all
-	of its parents.
-+
-However, it is not very useful in general, although it
-*is* useful on a file-by-file basis.

+NAME
+----
+git-worktree - Manage multiple working trees
+
+
+SYNOPSIS
+--------
+[verse]
+'git worktree add' [-f] [--detach] [-b <new-branch>] <path> [<branch>]
+'git worktree prune' [-n] [-v] [--expire <expire>]
+
+DESCRIPTION
+-----------
+
+Manage multiple working trees attached to the same repository.
+
+A git repository can support multiple working trees, allowing you to check
+out more than one branch at a time.  With `git worktree add` a new working
+tree is associated with the repository.  This new working tree is called a
+"linked working tree" as opposed to the "main working tree" prepared by "git
+init" or "git clone".  A repository has one main working tree (if it's not a
+bare repository) and zero or more linked working trees.
+
+When you are done with a linked working tree you can simply delete it.
+The working tree's administrative files in the repository (see
+"DETAILS" below) will eventually be removed automatically (see
+`gc.worktreePruneExpire` in linkgit:git-config[1]), or you can run
+`git worktree prune` in the main or any linked working tree to
+clean up any stale administrative files.
+
+If you move a linked working tree to another file system, or
+within a file system that does not support hard links, you need to run
+at least one git command inside the linked working tree
+(e.g. `git status`) in order to update its administrative files in the
+repository so that they do not get automatically pruned.
+
+If a linked working tree is stored on a portable device or network share
+which is not always mounted, you can prevent its administrative files from
+being pruned by creating a file named 'locked' alongside the other
+administrative files, optionally containing a plain text reason that
+pruning should be suppressed. See section "DETAILS" for more information.
+
+COMMANDS
+--------
+add <path> [<branch>]::
+
+Create `<path>` and checkout `<branch>` into it. The new working directory
+is linked to the current repository, sharing everything except working
+directory specific files such as HEAD, index, etc.
++
+If `<branch>` is omitted and neither `-b` nor `-B` nor `--detached` used,
+then, as a convenience, a new branch based at HEAD is created automatically,
+as if `-b $(basename <path>)` was specified.
+
+prune::
+
+Prune working tree information in $GIT_DIR/worktrees.
+
+OPTIONS
+-------
+
+-f::
+--force::
+	By default, `add` refuses to create a new working tree when `<branch>`
+	is already checked out by another working tree. This option overrides
+	that safeguard.
+
+-b <new-branch>::
+-B <new-branch>::
+	With `add`, create a new branch named `<new-branch>` starting at
+	`<branch>`, and check out `<new-branch>` into the new working tree.
+	If `<branch>` is omitted, it defaults to HEAD.
+	By default, `-b` refuses to create a new branch if it already
+	exists. `-B` overrides this safeguard, resetting `<new-branch>` to
+	`<branch>`.
+
+--detach::
+	With `add`, detach HEAD in the new working tree. See "DETACHED HEAD"
+	in linkgit:git-checkout[1].
+
+-n::
+--dry-run::
+	With `prune`, do not remove anything; just report what it would
+	remove.
+
+-v::
+--verbose::
+	With `prune`, report all removals.
+
+--expire <time>::
+	With `prune`, only expire unused working trees older than <time>.
+
+DETAILS
+-------
+Each linked working tree has a private sub-directory in the repository's
+$GIT_DIR/worktrees directory.  The private sub-directory's name is usually
+the base name of the linked working tree's path, possibly appended with a
+number to make it unique.  For example, when `$GIT_DIR=/path/main/.git` the
+command `git worktree add /path/other/test-next next` creates the linked
+working tree in `/path/other/test-next` and also creates a
+`$GIT_DIR/worktrees/test-next` directory (or `$GIT_DIR/worktrees/test-next1`
+if `test-next` is already taken).
+
+Within a linked working tree, $GIT_DIR is set to point to this private
+directory (e.g. `/path/main/.git/worktrees/test-next` in the example) and
+$GIT_COMMON_DIR is set to point back to the main working tree's $GIT_DIR
+(e.g. `/path/main/.git`). These settings are made in a `.git` file located at
+the top directory of the linked working tree.
+
+Path resolution via `git rev-parse --git-path` uses either
+$GIT_DIR or $GIT_COMMON_DIR depending on the path. For example, in the
+linked working tree `git rev-parse --git-path HEAD` returns
+`/path/main/.git/worktrees/test-next/HEAD` (not
+`/path/other/test-next/.git/HEAD` or `/path/main/.git/HEAD`) while `git
+rev-parse --git-path refs/heads/master` uses
+$GIT_COMMON_DIR and returns `/path/main/.git/refs/heads/master`,
+since refs are shared across all working trees.
+
+See linkgit:gitrepository-layout[5] for more information. The rule of
+thumb is do not make any assumption about whether a path belongs to
+$GIT_DIR or $GIT_COMMON_DIR when you need to directly access something
+inside $GIT_DIR. Use `git rev-parse --git-path` to get the final path.
+
+To prevent a $GIT_DIR/worktrees entry from being pruned (which
+can be useful in some situations, such as when the
+entry's working tree is stored on a portable device), add a file named
+'locked' to the entry's directory. The file contains the reason in
+plain text. For example, if a linked working tree's `.git` file points
+to `/path/main/.git/worktrees/test-next` then a file named
+`/path/main/.git/worktrees/test-next/locked` will prevent the
+`test-next` entry from being pruned.  See
+linkgit:gitrepository-layout[5] for details.
+
+EXAMPLES
+--------
+You are in the middle of a refactoring session and your boss comes in and
+demands that you fix something immediately. You might typically use
+linkgit:git-stash[1] to store your changes away temporarily, however, your
+working tree is in such a state of disarray (with new, moved, and removed
+files, and other bits and pieces strewn around) that you don't want to risk
+disturbing any of it. Instead, you create a temporary linked working tree to
+make the emergency fix, remove it when done, and then resume your earlier
+refactoring session.
+
+------------
+$ git worktree add -b emergency-fix ../temp master
+$ pushd ../temp
+# ... hack hack hack ...
+$ git commit -a -m 'emergency fix for boss'
+$ popd
+$ rm -rf ../temp
+$ git worktree prune
+------------
+
+BUGS
+----
+Multiple checkout in general is still experimental, and the support
+for submodules is incomplete. It is NOT recommended to make multiple
+checkouts of a superproject.
+
+git-worktree could provide more automation for tasks currently
+performed manually, such as:
+
+- `remove` to remove a linked working tree and its administrative files (and
+  warn if the working tree is dirty)
+- `mv` to move or rename a working tree and update its administrative files
+- `list` to list linked working trees
+- `lock` to prevent automatic pruning of administrative files (for instance,
+  for a working tree on a portable device)

++
+This option affects options that expect path name like `--git-dir` and

+Note that omitting the `=` in `git -c foo.bar ...` is allowed and sets
+`foo.bar` to the boolean true value (just like `[foo]bar` would in a

+'GIT_WORK_TREE'::
+	Set the path to the root of the working tree.
+	This can also be controlled by the '--work-tree' command-line
+	option and the core.worktree configuration variable.
+
+'GIT_NAMESPACE'::
+	Set the Git namespace; see linkgit:gitnamespaces[7] for details.
+	The '--namespace' command-line option also sets this value.
+
+'GIT_CEILING_DIRECTORIES'::
+	This should be a colon-separated list of absolute paths.  If
+	set, it is a list of directories that Git should not chdir up
+	into while looking for a repository directory (useful for
+	excluding slow-loading network directories).  It will not
+	exclude the current working directory or a GIT_DIR set on the
+	command line or in the environment.  Normally, Git has to read
+	the entries in this list and resolve any symlink that
+	might be present in order to compare them with the current
+	directory.  However, if even this access is slow, you
+	can add an empty entry to the list to tell Git that the
+	subsequent entries are not symlinks and needn't be resolved;
+	e.g.,
+	'GIT_CEILING_DIRECTORIES=/maybe/symlink::/very/slow/non/symlink'.
+
+'GIT_DISCOVERY_ACROSS_FILESYSTEM'::
+	When run in a directory that does not have ".git" repository
+	directory, Git tries to find such a directory in the parent
+	directories to find the top of the working tree, but by default it
+	does not cross filesystem boundaries.  This environment variable
+	can be set to true to tell Git not to stop at filesystem
+	boundaries.  Like 'GIT_CEILING_DIRECTORIES', this will not affect
+	an explicit repository directory set via 'GIT_DIR' or on the
+	command line.
+
+'GIT_COMMON_DIR'::
+	If this variable is set to a path, non-worktree files that are
+	normally in $GIT_DIR will be taken from this path
+	instead. Worktree-specific files such as HEAD or index are
+	taken from $GIT_DIR. See linkgit:gitrepository-layout[5] and
+	linkgit:git-worktree[1] for
+	details. This variable has lower precedence than other path
+	variables such as GIT_INDEX_FILE, GIT_OBJECT_DIRECTORY...

+
 'GIT_PAGER'::
-	This environment variable overrides `$PAGER`.
+	This environment variable overrides `$PAGER`. If it is set

+	a pager.  See also the `core.pager` option in

+
+'GIT_EDITOR'::
+	This environment variable overrides `$EDITOR` and `$VISUAL`.
+	It is used by several Git commands when, on interactive mode,
+	an editor is to be launched. See also linkgit:git-var[1]
+	and the `core.editor` option in linkgit:git-config[1].
+
+'GIT_SSH'::
+'GIT_SSH_COMMAND'::
+	If either of these environment variables is set then 'git fetch'
+	and 'git push' will use the specified command instead of 'ssh'
+	when they need to connect to a remote system.
+	The command will be given exactly two or four arguments: the
+	'username@host' (or just 'host') from the URL and the shell
+	command to execute on that remote system, optionally preceded by
+	'-p' (literally) and the 'port' from the URL when it specifies
+	something other than the default SSH port.
++
+`$GIT_SSH_COMMAND` takes precedence over `$GIT_SSH`, and is interpreted
+by the shell, which allows additional arguments to be included.
+`$GIT_SSH` on the other hand must be just the path to a program
+(which can be a wrapper shell script, if additional arguments are
+needed).
++
+Usually it is easier to configure any desired options through your
+personal `.ssh/config` file.  Please consult your ssh documentation
+for further details.
+
+'GIT_ASKPASS'::
+	If this environment variable is set, then Git commands which need to
+	acquire passwords or passphrases (e.g. for HTTP or IMAP authentication)
+	will call this program with a suitable prompt as command-line argument
+	and read the password from its STDOUT. See also the 'core.askPass'
+	option in linkgit:git-config[1].
+
+'GIT_TERMINAL_PROMPT'::
+	If this environment variable is set to `0`, git will not prompt
+	on the terminal (e.g., when asking for HTTP authentication).
+
+'GIT_CONFIG_NOSYSTEM'::
+	Whether to skip reading settings from the system-wide
+	`$(prefix)/etc/gitconfig` file.  This environment variable can
+	be used along with `$HOME` and `$XDG_CONFIG_HOME` to create a
+	predictable environment for a picky script, or you can set it
+	temporarily to avoid using a buggy `/etc/gitconfig` file while
+	waiting for someone with sufficient permissions to fix it.
+
+'GIT_FLUSH'::
+	If this environment variable is set to "1", then commands such
+	as 'git blame' (in incremental mode), 'git rev-list', 'git log',
+	'git check-attr' and 'git check-ignore' will
+	force a flush of the output stream after each record have been
+	flushed. If this
+	variable is set to "0", the output of these commands will be done
+	using completely buffered I/O.   If this environment variable is
+	not set, Git will choose buffered or record-oriented flushing
+	based on whether stdout appears to be redirected to a file or not.
 
 'GIT_TRACE'::
-	If this variable is set to "1", "2" or "true" (comparison
-	is case insensitive), git will print `trace:` messages on
-	stderr telling about alias expansion, built-in command
-	execution and external command execution.
-	If this variable is set to an integer value greater than 1
-	and lower than 10 (strictly) then git will interpret this
-	value as an open file descriptor and will try to write the
-	trace messages into this file descriptor.
-	Alternatively, if this variable is set to an absolute path
-	(starting with a '/' character), git will interpret this
-	as a file path and will try to write the trace messages
-	into it.
+	Enables general trace messages, e.g. alias expansion, built-in
+	command execution and external command execution.
++
+If this variable is set to "1", "2" or "true" (comparison
+is case insensitive), trace messages will be printed to
+stderr.
++
+If the variable is set to an integer value greater than 2
+and lower than 10 (strictly) then Git will interpret this
+value as an open file descriptor and will try to write the
+trace messages into this file descriptor.
++
+Alternatively, if the variable is set to an absolute path
+(starting with a '/' character), Git will interpret this
+as a file path and will try to write the trace messages
+into it.
++
+Unsetting the variable, or setting it to empty, "0" or
+"false" (case insensitive) disables trace messages.
+
+'GIT_TRACE_PACK_ACCESS'::
+	Enables trace messages for all accesses to any packs. For each
+	access, the pack file name and an offset in the pack is
+	recorded. This may be helpful for troubleshooting some
+	pack-related performance problems.
+	See 'GIT_TRACE' for available trace output options.
+
+'GIT_TRACE_PACKET'::
+	Enables trace messages for all packets coming in or out of a
+	given program. This can help with debugging object negotiation
+	or other protocol issues. Tracing is turned off at a packet
+	starting with "PACK" (but see 'GIT_TRACE_PACKFILE' below).
+	See 'GIT_TRACE' for available trace output options.
+
+'GIT_TRACE_PACKFILE'::
+	Enables tracing of packfiles sent or received by a
+	given program. Unlike other trace output, this trace is
+	verbatim: no headers, and no quoting of binary data. You almost
+	certainly want to direct into a file (e.g.,
+	`GIT_TRACE_PACKFILE=/tmp/my.pack`) rather than displaying it on
+	the terminal or mixing it with other trace output.
++
+Note that this is currently only implemented for the client side
+of clones and fetches.
+
+'GIT_TRACE_PERFORMANCE'::
+	Enables performance related trace messages, e.g. total execution
+	time of each Git command.
+	See 'GIT_TRACE' for available trace output options.
+
+'GIT_TRACE_SETUP'::
+	Enables trace messages printing the .git, working tree and current
+	working directory after Git has completed its setup phase.
+	See 'GIT_TRACE' for available trace output options.
+
+'GIT_TRACE_SHALLOW'::
+	Enables trace messages that can help debugging fetching /
+	cloning of shallow repositories.
+	See 'GIT_TRACE' for available trace output options.
+
+GIT_LITERAL_PATHSPECS::
+	Setting this variable to `1` will cause Git to treat all
+	pathspecs literally, rather than as glob patterns. For example,
+	running `GIT_LITERAL_PATHSPECS=1 git log -- '*.c'` will search
+	for commits that touch the path `*.c`, not any paths that the
+	glob `*.c` matches. You might want this if you are feeding
+	literal paths to Git (e.g., paths previously given to you by
+	`git ls-tree`, `--raw` diff output, etc).
+
+GIT_GLOB_PATHSPECS::
+	Setting this variable to `1` will cause Git to treat all
+	pathspecs as glob patterns (aka "glob" magic).
+
+GIT_NOGLOB_PATHSPECS::
+	Setting this variable to `1` will cause Git to treat all
+	pathspecs as literal (aka "literal" magic).
+
+GIT_ICASE_PATHSPECS::
+	Setting this variable to `1` will cause Git to treat all
+	pathspecs as case-insensitive.
+
+'GIT_REFLOG_ACTION'::
+	When a ref is updated, reflog entries are created to keep
+	track of the reason why the ref was updated (which is
+	typically the name of the high-level command that updated
+	the ref), in addition to the old and new values of the ref.
+	A scripted Porcelain command can use set_reflog_action
+	helper function in `git-sh-setup` to set its name to this
+	variable when it is invoked as the top level command by the
+	end user, to be recorded in the body of the reflog.
+
+`GIT_REF_PARANOIA`::
+	If set to `1`, include broken or badly named refs when iterating
+	over lists of refs. In a normal, non-corrupted repository, this
+	does nothing. However, enabling it may help git to detect and
+	abort some operations in the presence of broken refs. Git sets
+	this variable automatically when performing destructive
+	operations like linkgit:git-prune[1]. You should not need to set
+	it yourself unless you want to be paranoid about making sure
+	an operation has touched every ref (e.g., because you are
+	cloning a repository to make a backup).
+
+`GIT_ALLOW_PROTOCOL`::
+	If set, provide a colon-separated list of protocols which are
+	allowed to be used with fetch/push/clone. This is useful to
+	restrict recursive submodule initialization from an untrusted
+	repository. Any protocol not mentioned will be disallowed (i.e.,
+	this is a whitelist, not a blacklist). If the variable is not
+	set at all, all protocols are enabled.  The protocol names
+	currently used by git are:
+
+	  - `file`: any local file-based path (including `file://` URLs,
+	    or local paths)
+
+	  - `git`: the anonymous git protocol over a direct TCP
+	    connection (or proxy, if configured)
+
+	  - `ssh`: git over ssh (including `host:path` syntax,
+	    `git+ssh://`, etc).
+
+	  - `rsync`: git over rsync
+
+	  - `http`: git over http, both "smart http" and "dumb http".
+	    Note that this does _not_ include `https`; if you want both,
+	    you should specify both as `http:https`.
+
+	  - any external helpers are named by their protocol (e.g., use
+	    `hg` to allow the `git-remote-hg` helper)

+
+More detail on the following is available from the
+link:user-manual.html#git-concepts[Git concepts chapter of the
+user-manual] and linkgit:gitcore-tutorial[7].
+
+A Git project normally consists of a working directory with a ".git"
+subdirectory at the top level.  The .git directory contains, among other
+things, a compressed object database representing the complete history
+of the project, an "index" file which links that history to the current
+contents of the working tree, and named pointers into that history such
+as tags and branch heads.
+
+The object database contains objects of three main types: blobs, which
+hold file data; trees, which point to blobs and other trees to build up
+directory hierarchies; and commits, which each reference a single tree
+and some number of parent commits.
+
+The commit, equivalent to what other systems call a "changeset" or
+"version", represents a step in the project's history, and each parent
+represents an immediately preceding step.  Commits with more than one
+parent represent merges of independent lines of development.
+
+All objects are named by the SHA-1 hash of their contents, normally
+written as a string of 40 hex digits.  Such names are globally unique.
+The entire history leading up to a commit can be vouched for by signing
+just that commit.  A fourth object type, the tag, is provided for this
+purpose.
+
+When first created, objects are stored in individual files, but for
+efficiency may later be compressed together into "pack files".
+
+Named pointers called refs mark interesting points in history.  A ref
+may contain the SHA-1 name of an object or the name of another ref.  Refs
+with names beginning `ref/head/` contain the SHA-1 name of the most
+recent commit (or "head") of a branch under development.  SHA-1 names of
+tags of interest are stored under `ref/tags/`.  A special ref named
+`HEAD` contains the name of the currently checked-out branch.
+
+The index file is initialized with a list of all paths and, for each
+path, a blob object and a set of attributes.  The blob object represents
+the contents of the file as of the head of the current branch.  The
+attributes (last modified time, size, etc.) are taken from the
+corresponding file in the working tree.  Subsequent changes to the
+working tree can be found by comparing these attributes.  The index may
+be updated with new content, and new commits may be created from the
+content stored in the index.
+
+The index is also capable of storing multiple entries (called "stages")
+for a given pathname.  These stages are used to hold the various
+unmerged version of a file when a merge is in progress.

+================
+
+NAME
+----
+gitattributes - defining attributes per path
+
+SYNOPSIS
+--------
+$GIT_DIR/info/attributes, .gitattributes
+
+
+DESCRIPTION
+-----------
+
+A `gitattributes` file is a simple text file that gives
+`attributes` to pathnames.
+
+Each line in `gitattributes` file is of form:
+
+	pattern	attr1 attr2 ...
+
+That is, a pattern followed by an attributes list,
+separated by whitespaces.  When the pattern matches the
+path in question, the attributes listed on the line are given to
+the path.
+
+Each attribute can be in one of these states for a given path:
+
+Set::
+
+	The path has the attribute with special value "true";
+	this is specified by listing only the name of the
+	attribute in the attribute list.
+
+Unset::
+
+	The path has the attribute with special value "false";
+	this is specified by listing the name of the attribute
+	prefixed with a dash `-` in the attribute list.
+
+Set to a value::
+
+	The path has the attribute with specified string value;
+	this is specified by listing the name of the attribute
+	followed by an equal sign `=` and its value in the
+	attribute list.
+
+Unspecified::
+
+	No pattern matches the path, and nothing says if
+	the path has or does not have the attribute, the
+	attribute for the path is said to be Unspecified.
+
+When more than one pattern matches the path, a later line
+overrides an earlier line.  This overriding is done per
+attribute.  The rules how the pattern matches paths are the
+same as in `.gitignore` files; see linkgit:gitignore[5].
+Unlike `.gitignore`, negative patterns are forbidden.
+
+When deciding what attributes are assigned to a path, Git
+consults `$GIT_DIR/info/attributes` file (which has the highest
+precedence), `.gitattributes` file in the same directory as the
+path in question, and its parent directories up to the toplevel of the
+work tree (the further the directory that contains `.gitattributes`
+is from the path in question, the lower its precedence). Finally
+global and system-wide files are considered (they have the lowest
+precedence).
+
+When the `.gitattributes` file is missing from the work tree, the
+path in the index is used as a fall-back.  During checkout process,
+`.gitattributes` in the index is used and then the file in the
+working tree is used as a fall-back.
+
+If you wish to affect only a single repository (i.e., to assign
+attributes to files that are particular to
+one user's workflow for that repository), then
+attributes should be placed in the `$GIT_DIR/info/attributes` file.
+Attributes which should be version-controlled and distributed to other
+repositories (i.e., attributes of interest to all users) should go into
+`.gitattributes` files. Attributes that should affect all repositories
+for a single user should be placed in a file specified by the
+`core.attributesFile` configuration option (see linkgit:git-config[1]).
+Its default value is $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME
+is either not set or empty, $HOME/.config/git/attributes is used instead.
+Attributes for all users on a system should be placed in the
+`$(prefix)/etc/gitattributes` file.
+
+Sometimes you would need to override an setting of an attribute
+for a path to `Unspecified` state.  This can be done by listing
+the name of the attribute prefixed with an exclamation point `!`.
+
+
+EFFECTS
+-------
+
+Certain operations by Git can be influenced by assigning
+particular attributes to a path.  Currently, the following
+operations are attributes-aware.
+
+Checking-out and checking-in
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+These attributes affect how the contents stored in the
+repository are copied to the working tree files when commands
+such as 'git checkout' and 'git merge' run.  They also affect how
+Git stores the contents you prepare in the working tree in the
+repository upon 'git add' and 'git commit'.
+
+`text`
+^^^^^^
+
+This attribute enables and controls end-of-line normalization.  When a
+text file is normalized, its line endings are converted to LF in the
+repository.  To control what line ending style is used in the working
+directory, use the `eol` attribute for a single file and the
+`core.eol` configuration variable for all text files.
+
+Set::
+
+	Setting the `text` attribute on a path enables end-of-line
+	normalization and marks the path as a text file.  End-of-line
+	conversion takes place without guessing the content type.
+
+Unset::
+
+	Unsetting the `text` attribute on a path tells Git not to
+	attempt any end-of-line conversion upon checkin or checkout.
+
+Set to string value "auto"::
+
+	When `text` is set to "auto", the path is marked for automatic
+	end-of-line normalization.  If Git decides that the content is
+	text, its line endings are normalized to LF on checkin.
+
+Unspecified::
+
+	If the `text` attribute is unspecified, Git uses the
+	`core.autocrlf` configuration variable to determine if the
+	file should be converted.
+
+Any other value causes Git to act as if `text` has been left
+unspecified.
+
+`eol`
+^^^^^
+
+This attribute sets a specific line-ending style to be used in the
+working directory.  It enables end-of-line normalization without any
+content checks, effectively setting the `text` attribute.
+
+Set to string value "crlf"::
+
+	This setting forces Git to normalize line endings for this
+	file on checkin and convert them to CRLF when the file is
+	checked out.
+
+Set to string value "lf"::
+
+	This setting forces Git to normalize line endings to LF on
+	checkin and prevents conversion to CRLF when the file is
+	checked out.
+
+Backwards compatibility with `crlf` attribute
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For backwards compatibility, the `crlf` attribute is interpreted as
+follows:
+
+------------------------
+crlf		text
+-crlf		-text
+crlf=input	eol=lf
+------------------------
+
+End-of-line conversion
+^^^^^^^^^^^^^^^^^^^^^^
+
+While Git normally leaves file contents alone, it can be configured to
+normalize line endings to LF in the repository and, optionally, to
+convert them to CRLF when files are checked out.
+
+Here is an example that will make Git normalize .txt, .vcproj and .sh
+files, ensure that .vcproj files have CRLF and .sh files have LF in
+the working directory, and prevent .jpg files from being normalized
+regardless of their content.
+
+------------------------
+*.txt		text
+*.vcproj	eol=crlf
+*.sh		eol=lf
+*.jpg		-text
+------------------------
+
+Other source code management systems normalize all text files in their
+repositories, and there are two ways to enable similar automatic
+normalization in Git.
+
+If you simply want to have CRLF line endings in your working directory
+regardless of the repository you are working with, you can set the
+config variable "core.autocrlf" without changing any attributes.
+
+------------------------
+[core]
+	autocrlf = true
+------------------------
+
+This does not force normalization of all text files, but does ensure
+that text files that you introduce to the repository have their line
+endings normalized to LF when they are added, and that files that are
+already normalized in the repository stay normalized.
+
+If you want to interoperate with a source code management system that
+enforces end-of-line normalization, or you simply want all text files
+in your repository to be normalized, you should instead set the `text`
+attribute to "auto" for _all_ files.
+
+------------------------
+*	text=auto
+------------------------
+
+This ensures that all files that Git considers to be text will have
+normalized (LF) line endings in the repository.  The `core.eol`
+configuration variable controls which line endings Git will use for
+normalized files in your working directory; the default is to use the
+native line ending for your platform, or CRLF if `core.autocrlf` is
+set.
+
+NOTE: When `text=auto` normalization is enabled in an existing
+repository, any text files containing CRLFs should be normalized.  If
+they are not they will be normalized the next time someone tries to
+change them, causing unfortunate misattribution.  From a clean working
+directory:
+
+-------------------------------------------------
+$ echo "* text=auto" >>.gitattributes
+$ rm .git/index     # Remove the index to force Git to
+$ git reset         # re-scan the working directory
+$ git status        # Show files that will be normalized
+$ git add -u
+$ git add .gitattributes
+$ git commit -m "Introduce end-of-line normalization"
+-------------------------------------------------
+
+If any files that should not be normalized show up in 'git status',
+unset their `text` attribute before running 'git add -u'.
+
+------------------------
+manual.pdf	-text
+------------------------
+
+Conversely, text files that Git does not detect can have normalization
+enabled manually.
+
+------------------------
+weirdchars.txt	text
+------------------------
+
+If `core.safecrlf` is set to "true" or "warn", Git verifies if
+the conversion is reversible for the current setting of
+`core.autocrlf`.  For "true", Git rejects irreversible
+conversions; for "warn", Git only prints a warning but accepts
+an irreversible conversion.  The safety triggers to prevent such
+a conversion done to the files in the work tree, but there are a
+few exceptions.  Even though...
+
+- 'git add' itself does not touch the files in the work tree, the
+  next checkout would, so the safety triggers;
+
+- 'git apply' to update a text file with a patch does touch the files
+  in the work tree, but the operation is about text files and CRLF
+  conversion is about fixing the line ending inconsistencies, so the
+  safety does not trigger;
+
+- 'git diff' itself does not touch the files in the work tree, it is
+  often run to inspect the changes you intend to next 'git add'.  To
+  catch potential problems early, safety triggers.
+
+
+`ident`
+^^^^^^^
+
+When the attribute `ident` is set for a path, Git replaces
+`$Id$` in the blob object with `$Id:`, followed by the
+40-character hexadecimal blob object name, followed by a dollar
+sign `$` upon checkout.  Any byte sequence that begins with
+`$Id:` and ends with `$` in the worktree file is replaced
+with `$Id$` upon check-in.
+
+
+`filter`
+^^^^^^^^
+
+A `filter` attribute can be set to a string value that names a
+filter driver specified in the configuration.
+
+A filter driver consists of a `clean` command and a `smudge`
+command, either of which can be left unspecified.  Upon
+checkout, when the `smudge` command is specified, the command is
+fed the blob object from its standard input, and its standard
+output is used to update the worktree file.  Similarly, the
+`clean` command is used to convert the contents of worktree file
+upon checkin.
+
+One use of the content filtering is to massage the content into a shape
+that is more convenient for the platform, filesystem, and the user to use.
+For this mode of operation, the key phrase here is "more convenient" and
+not "turning something unusable into usable".  In other words, the intent
+is that if someone unsets the filter driver definition, or does not have
+the appropriate filter program, the project should still be usable.
+
+Another use of the content filtering is to store the content that cannot
+be directly used in the repository (e.g. a UUID that refers to the true
+content stored outside Git, or an encrypted content) and turn it into a
+usable form upon checkout (e.g. download the external content, or decrypt
+the encrypted content).
+
+These two filters behave differently, and by default, a filter is taken as
+the former, massaging the contents into more convenient shape.  A missing
+filter driver definition in the config, or a filter driver that exits with
+a non-zero status, is not an error but makes the filter a no-op passthru.
+
+You can declare that a filter turns a content that by itself is unusable
+into a usable content by setting the filter.<driver>.required configuration
+variable to `true`.
+
+For example, in .gitattributes, you would assign the `filter`
+attribute for paths.
+
+------------------------
+*.c	filter=indent
+------------------------
+
+Then you would define a "filter.indent.clean" and "filter.indent.smudge"
+configuration in your .git/config to specify a pair of commands to
+modify the contents of C programs when the source files are checked
+in ("clean" is run) and checked out (no change is made because the
+command is "cat").
+
+------------------------
+[filter "indent"]
+	clean = indent
+	smudge = cat
+------------------------
+
+For best results, `clean` should not alter its output further if it is
+run twice ("clean->clean" should be equivalent to "clean"), and
+multiple `smudge` commands should not alter `clean`'s output
+("smudge->smudge->clean" should be equivalent to "clean").  See the
+section on merging below.
+
+The "indent" filter is well-behaved in this regard: it will not modify
+input that is already correctly indented.  In this case, the lack of a
+smudge filter means that the clean filter _must_ accept its own output
+without modifying it.
+
+If a filter _must_ succeed in order to make the stored contents usable,
+you can declare that the filter is `required`, in the configuration:
+
+------------------------
+[filter "crypt"]
+	clean = openssl enc ...
+	smudge = openssl enc -d ...
+	required
+------------------------
+
+Sequence "%f" on the filter command line is replaced with the name of
+the file the filter is working on.  A filter might use this in keyword
+substitution.  For example:
+
+------------------------
+[filter "p4"]
+	clean = git-p4-filter --clean %f
+	smudge = git-p4-filter --smudge %f
+------------------------
+
+
+Interaction between checkin/checkout attributes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In the check-in codepath, the worktree file is first converted
+with `filter` driver (if specified and corresponding driver
+defined), then the result is processed with `ident` (if
+specified), and then finally with `text` (again, if specified
+and applicable).
+
+In the check-out codepath, the blob content is first converted
+with `text`, and then `ident` and fed to `filter`.
+
+
+Merging branches with differing checkin/checkout attributes
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you have added attributes to a file that cause the canonical
+repository format for that file to change, such as adding a
+clean/smudge filter or text/eol/ident attributes, merging anything
+where the attribute is not in place would normally cause merge
+conflicts.
+
+To prevent these unnecessary merge conflicts, Git can be told to run a
+virtual check-out and check-in of all three stages of a file when
+resolving a three-way merge by setting the `merge.renormalize`
+configuration variable.  This prevents changes caused by check-in
+conversion from causing spurious merge conflicts when a converted file
+is merged with an unconverted file.
+
+As long as a "smudge->clean" results in the same output as a "clean"
+even on files that are already smudged, this strategy will
+automatically resolve all filter-related conflicts.  Filters that do
+not act in this way may cause additional merge conflicts that must be
+resolved manually.
+
+
+Generating diff text
+~~~~~~~~~~~~~~~~~~~~
+
+`diff`
+^^^^^^
+
+The attribute `diff` affects how Git generates diffs for particular
+files. It can tell Git whether to generate a textual patch for the path
+or to treat the path as a binary file.  It can also affect what line is
+shown on the hunk header `@@ -k,l +n,m @@` line, tell Git to use an
+external command to generate the diff, or ask Git to convert binary
+files to a text format before generating the diff.
+
+Set::
+
+	A path to which the `diff` attribute is set is treated
+	as text, even when they contain byte values that
+	normally never appear in text files, such as NUL.
+
+Unset::
+
+	A path to which the `diff` attribute is unset will
+	generate `Binary files differ` (or a binary patch, if
+	binary patches are enabled).
+
+Unspecified::
+
+	A path to which the `diff` attribute is unspecified
+	first gets its contents inspected, and if it looks like
+	text and is smaller than core.bigFileThreshold, it is treated
+	as text. Otherwise it would generate `Binary files differ`.
+
+String::
+
+	Diff is shown using the specified diff driver.  Each driver may
+	specify one or more options, as described in the following
+	section. The options for the diff driver "foo" are defined
+	by the configuration variables in the "diff.foo" section of the
+	Git config file.
+
+
+Defining an external diff driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The definition of a diff driver is done in `gitconfig`, not
+`gitattributes` file, so strictly speaking this manual page is a
+wrong place to talk about it.  However...
+
+To define an external diff driver `jcdiff`, add a section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
+
+----------------------------------------------------------------
+[diff "jcdiff"]
+	command = j-c-diff
+----------------------------------------------------------------
+
+When Git needs to show you a diff for the path with `diff`
+attribute set to `jcdiff`, it calls the command you specified
+with the above configuration, i.e. `j-c-diff`, with 7
+parameters, just like `GIT_EXTERNAL_DIFF` program is called.
+See linkgit:git[1] for details.
+
+
+Defining a custom hunk-header
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Each group of changes (called a "hunk") in the textual diff output
+is prefixed with a line of the form:
+
+	@@ -k,l +n,m @@ TEXT
+
+This is called a 'hunk header'.  The "TEXT" portion is by default a line
+that begins with an alphabet, an underscore or a dollar sign; this
+matches what GNU 'diff -p' output uses.  This default selection however
+is not suited for some contents, and you can use a customized pattern
+to make a selection.
+
+First, in .gitattributes, you would assign the `diff` attribute
+for paths.
+
+------------------------
+*.tex	diff=tex
+------------------------
+
+Then, you would define a "diff.tex.xfuncname" configuration to
+specify a regular expression that matches a line that you would
+want to appear as the hunk header "TEXT". Add a section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
+
+------------------------
+[diff "tex"]
+	xfuncname = "^(\\\\(sub)*section\\{.*)$"
+------------------------
+
+Note.  A single level of backslashes are eaten by the
+configuration file parser, so you would need to double the
+backslashes; the pattern above picks a line that begins with a
+backslash, and zero or more occurrences of `sub` followed by
+`section` followed by open brace, to the end of line.
+
+There are a few built-in patterns to make this easier, and `tex`
+is one of them, so you do not have to write the above in your
+configuration file (you still need to enable this with the
+attribute mechanism, via `.gitattributes`).  The following built in
+patterns are available:
+
+- `ada` suitable for source code in the Ada language.
+
+- `bibtex` suitable for files with BibTeX coded references.
+
+- `cpp` suitable for source code in the C and C++ languages.
+
+- `csharp` suitable for source code in the C# language.
+
+- `fortran` suitable for source code in the Fortran language.
+
+- `fountain` suitable for Fountain documents.
+
+- `html` suitable for HTML/XHTML documents.
+
+- `java` suitable for source code in the Java language.
+
+- `matlab` suitable for source code in the MATLAB language.
+
+- `objc` suitable for source code in the Objective-C language.
+
+- `pascal` suitable for source code in the Pascal/Delphi language.
+
+- `perl` suitable for source code in the Perl language.
+
+- `php` suitable for source code in the PHP language.
+
+- `python` suitable for source code in the Python language.
+
+- `ruby` suitable for source code in the Ruby language.
+
+- `tex` suitable for source code for LaTeX documents.
+
+
+Customizing word diff
+^^^^^^^^^^^^^^^^^^^^^
+
+You can customize the rules that `git diff --word-diff` uses to
+split words in a line, by specifying an appropriate regular expression
+in the "diff.*.wordRegex" configuration variable.  For example, in TeX
+a backslash followed by a sequence of letters forms a command, but
+several such commands can be run together without intervening
+whitespace.  To separate them, use a regular expression in your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
+
+------------------------
+[diff "tex"]
+	wordRegex = "\\\\[a-zA-Z]+|[{}]|\\\\.|[^\\{}[:space:]]+"
+------------------------
+
+A built-in pattern is provided for all languages listed in the
+previous section.
+
+
+Performing text diffs of binary files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Sometimes it is desirable to see the diff of a text-converted
+version of some binary files. For example, a word processor
+document can be converted to an ASCII text representation, and
+the diff of the text shown. Even though this conversion loses
+some information, the resulting diff is useful for human
+viewing (but cannot be applied directly).
+
+The `textconv` config option is used to define a program for
+performing such a conversion. The program should take a single
+argument, the name of a file to convert, and produce the
+resulting text on stdout.
+
+For example, to show the diff of the exif information of a
+file instead of the binary information (assuming you have the
+exif tool installed), add the following section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file):
+
+------------------------
+[diff "jpg"]
+	textconv = exif
+------------------------
+
+NOTE: The text conversion is generally a one-way conversion;
+in this example, we lose the actual image contents and focus
+just on the text data. This means that diffs generated by
+textconv are _not_ suitable for applying. For this reason,
+only `git diff` and the `git log` family of commands (i.e.,
+log, whatchanged, show) will perform text conversion. `git
+format-patch` will never generate this output. If you want to
+send somebody a text-converted diff of a binary file (e.g.,
+because it quickly conveys the changes you have made), you
+should generate it separately and send it as a comment _in
+addition to_ the usual binary diff that you might send.
+
+Because text conversion can be slow, especially when doing a
+large number of them with `git log -p`, Git provides a mechanism
+to cache the output and use it in future diffs.  To enable
+caching, set the "cachetextconv" variable in your diff driver's
+config. For example:
+
+------------------------
+[diff "jpg"]
+	textconv = exif
+	cachetextconv = true
+------------------------
+
+This will cache the result of running "exif" on each blob
+indefinitely. If you change the textconv config variable for a
+diff driver, Git will automatically invalidate the cache entries
+and re-run the textconv filter. If you want to invalidate the
+cache manually (e.g., because your version of "exif" was updated
+and now produces better output), you can remove the cache
+manually with `git update-ref -d refs/notes/textconv/jpg` (where
+"jpg" is the name of the diff driver, as in the example above).
+
+Choosing textconv versus external diff
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you want to show differences between binary or specially-formatted
+blobs in your repository, you can choose to use either an external diff
+command, or to use textconv to convert them to a diff-able text format.
+Which method you choose depends on your exact situation.
+
+The advantage of using an external diff command is flexibility. You are
+not bound to find line-oriented changes, nor is it necessary for the
+output to resemble unified diff. You are free to locate and report
+changes in the most appropriate way for your data format.
+
+A textconv, by comparison, is much more limiting. You provide a
+transformation of the data into a line-oriented text format, and Git
+uses its regular diff tools to generate the output. There are several
+advantages to choosing this method:
+
+1. Ease of use. It is often much simpler to write a binary to text
+   transformation than it is to perform your own diff. In many cases,
+   existing programs can be used as textconv filters (e.g., exif,
+   odt2txt).
+
+2. Git diff features. By performing only the transformation step
+   yourself, you can still utilize many of Git's diff features,
+   including colorization, word-diff, and combined diffs for merges.
+
+3. Caching. Textconv caching can speed up repeated diffs, such as those
+   you might trigger by running `git log -p`.
+
+
+Marking files as binary
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git usually guesses correctly whether a blob contains text or binary
+data by examining the beginning of the contents. However, sometimes you
+may want to override its decision, either because a blob contains binary
+data later in the file, or because the content, while technically
+composed of text characters, is opaque to a human reader. For example,
+many postscript files contain only ASCII characters, but produce noisy
+and meaningless diffs.
+
+The simplest way to mark a file as binary is to unset the diff
+attribute in the `.gitattributes` file:
+
+------------------------
+*.ps -diff
+------------------------
+
+This will cause Git to generate `Binary files differ` (or a binary
+patch, if binary patches are enabled) instead of a regular diff.
+
+However, one may also want to specify other diff driver attributes. For
+example, you might want to use `textconv` to convert postscript files to
+an ASCII representation for human viewing, but otherwise treat them as
+binary files. You cannot specify both `-diff` and `diff=ps` attributes.
+The solution is to use the `diff.*.binary` config option:
+
+------------------------
+[diff "ps"]
+  textconv = ps2ascii
+  binary = true
+------------------------
+
+Performing a three-way merge
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`merge`
+^^^^^^^
+
+The attribute `merge` affects how three versions of a file are
+merged when a file-level merge is necessary during `git merge`,
+and other commands such as `git revert` and `git cherry-pick`.
+
+Set::
+
+	Built-in 3-way merge driver is used to merge the
+	contents in a way similar to 'merge' command of `RCS`
+	suite.  This is suitable for ordinary text files.
+
+Unset::
+
+	Take the version from the current branch as the
+	tentative merge result, and declare that the merge has
+	conflicts.  This is suitable for binary files that do
+	not have a well-defined merge semantics.
+
+Unspecified::
+
+	By default, this uses the same built-in 3-way merge
+	driver as is the case when the `merge` attribute is set.
+	However, the `merge.default` configuration variable can name
+	different merge driver to be used with paths for which the
+	`merge` attribute is unspecified.
+
+String::
+
+	3-way merge is performed using the specified custom
+	merge driver.  The built-in 3-way merge driver can be
+	explicitly specified by asking for "text" driver; the
+	built-in "take the current branch" driver can be
+	requested with "binary".
+
+
+Built-in merge drivers
+^^^^^^^^^^^^^^^^^^^^^^
+
+There are a few built-in low-level merge drivers defined that
+can be asked for via the `merge` attribute.
+
+text::
+
+	Usual 3-way file level merge for text files.  Conflicted
+	regions are marked with conflict markers `<<<<<<<`,
+	`=======` and `>>>>>>>`.  The version from your branch
+	appears before the `=======` marker, and the version
+	from the merged branch appears after the `=======`
+	marker.
+
+binary::
+
+	Keep the version from your branch in the work tree, but
+	leave the path in the conflicted state for the user to
+	sort out.
+
+union::
+
+	Run 3-way file level merge for text files, but take
+	lines from both versions, instead of leaving conflict
+	markers.  This tends to leave the added lines in the
+	resulting file in random order and the user should
+	verify the result. Do not use this if you do not
+	understand the implications.
+
+
+Defining a custom merge driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The definition of a merge driver is done in the `.git/config`
+file, not in the `gitattributes` file, so strictly speaking this
+manual page is a wrong place to talk about it.  However...
+
+To define a custom merge driver `filfre`, add a section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
+
+----------------------------------------------------------------
+[merge "filfre"]
+	name = feel-free merge driver
+	driver = filfre %O %A %B %L %P
+	recursive = binary
+----------------------------------------------------------------
+
+The `merge.*.name` variable gives the driver a human-readable
+name.
+
+The `merge.*.driver` variable's value is used to construct a
+command to run to merge ancestor's version (`%O`), current
+version (`%A`) and the other branches' version (`%B`).  These
+three tokens are replaced with the names of temporary files that
+hold the contents of these versions when the command line is
+built. Additionally, %L will be replaced with the conflict marker
+size (see below).
+
+The merge driver is expected to leave the result of the merge in
+the file named with `%A` by overwriting it, and exit with zero
+status if it managed to merge them cleanly, or non-zero if there
+were conflicts.
+
+The `merge.*.recursive` variable specifies what other merge
+driver to use when the merge driver is called for an internal
+merge between common ancestors, when there are more than one.
+When left unspecified, the driver itself is used for both
+internal merge and the final merge.
+
+The merge driver can learn the pathname in which the merged result
+will be stored via placeholder `%P`.
+
+
+`conflict-marker-size`
+^^^^^^^^^^^^^^^^^^^^^^
+
+This attribute controls the length of conflict markers left in
+the work tree file during a conflicted merge.  Only setting to
+the value to a positive integer has any meaningful effect.
+
+For example, this line in `.gitattributes` can be used to tell the merge
+machinery to leave much longer (instead of the usual 7-character-long)
+conflict markers when merging the file `Documentation/git-merge.txt`
+results in a conflict.
+
+------------------------
+Documentation/git-merge.txt	conflict-marker-size=32
+------------------------
+
+
+Checking whitespace errors
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`whitespace`
+^^^^^^^^^^^^
+
+The `core.whitespace` configuration variable allows you to define what
+'diff' and 'apply' should consider whitespace errors for all paths in
+the project (See linkgit:git-config[1]).  This attribute gives you finer
+control per path.
+
+Set::
+
+	Notice all types of potential whitespace errors known to Git.
+	The tab width is taken from the value of the `core.whitespace`
+	configuration variable.
+
+Unset::
+
+	Do not notice anything as error.
+
+Unspecified::
+
+	Use the value of the `core.whitespace` configuration variable to
+	decide what to notice as error.
+
+String::
+
+	Specify a comma separate list of common whitespace problems to
+	notice in the same format as the `core.whitespace` configuration
+	variable.
+
+
+Creating an archive
+~~~~~~~~~~~~~~~~~~~
+
+`export-ignore`
+^^^^^^^^^^^^^^^
+
+Files and directories with the attribute `export-ignore` won't be added to
+archive files.
+
+`export-subst`
+^^^^^^^^^^^^^^
+
+If the attribute `export-subst` is set for a file then Git will expand
+several placeholders when adding this file to an archive.  The
+expansion depends on the availability of a commit ID, i.e., if
+linkgit:git-archive[1] has been given a tree instead of a commit or a
+tag then no replacement will be done.  The placeholders are the same
+as those for the option `--pretty=format:` of linkgit:git-log[1],
+except that they need to be wrapped like this: `$Format:PLACEHOLDERS$`
+in the file.  E.g. the string `$Format:%H$` will be replaced by the
+commit hash.
+
+
+Packing objects
+~~~~~~~~~~~~~~~
+
+`delta`
+^^^^^^^
+
+Delta compression will not be attempted for blobs for paths with the
+attribute `delta` set to false.
+
+
+Viewing files in GUI tools
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+`encoding`
+^^^^^^^^^^
+
+The value of this attribute specifies the character encoding that should
+be used by GUI tools (e.g. linkgit:gitk[1] and linkgit:git-gui[1]) to
+display the contents of the relevant file. Note that due to performance
+considerations linkgit:gitk[1] does not use this attribute unless you
+manually enable per-file encodings in its options.
+
+If this attribute is not set or has an invalid value, the value of the
+`gui.encoding` configuration variable is used instead
+(See linkgit:git-config[1]).
+
+
+USING MACRO ATTRIBUTES
+----------------------
+
+You do not want any end-of-line conversions applied to, nor textual diffs
+produced for, any binary file you track.  You would need to specify e.g.
+
+------------
+*.jpg -text -diff
+------------
+
+but that may become cumbersome, when you have many attributes.  Using
+macro attributes, you can define an attribute that, when set, also
+sets or unsets a number of other attributes at the same time.  The
+system knows a built-in macro attribute, `binary`:
+
+------------
+*.jpg binary
+------------
+
+Setting the "binary" attribute also unsets the "text" and "diff"
+attributes as above.  Note that macro attributes can only be "Set",
+though setting one might have the effect of setting or unsetting other
+attributes or even returning other attributes to the "Unspecified"
+state.
+
+
+DEFINING MACRO ATTRIBUTES
+-------------------------
+
+Custom macro attributes can be defined only in top-level gitattributes
+files (`$GIT_DIR/info/attributes`, the `.gitattributes` file at the
+top level of the working tree, or the global or system-wide
+gitattributes files), not in `.gitattributes` files in working tree
+subdirectories.  The built-in macro attribute "binary" is equivalent
+to:
+
+------------
+[attr]binary -diff -merge -text
+------------
+
+
+EXAMPLE
+-------
+
+If you have these three `gitattributes` file:
+
+----------------------------------------------------------------
+(in $GIT_DIR/info/attributes)
+
+a*	foo !bar -baz
+
+(in .gitattributes)
+abc	foo bar baz
+
+(in t/.gitattributes)
+ab*	merge=filfre
+abc	-foo -bar
+*.c	frotz
+----------------------------------------------------------------
+
+the attributes given to path `t/abc` are computed as follows:
+
+1. By examining `t/.gitattributes` (which is in the same
+   directory as the path in question), Git finds that the first
+   line matches.  `merge` attribute is set.  It also finds that
+   the second line matches, and attributes `foo` and `bar`
+   are unset.
+
+2. Then it examines `.gitattributes` (which is in the parent
+   directory), and finds that the first line matches, but
+   `t/.gitattributes` file already decided how `merge`, `foo`
+   and `bar` attributes should be given to this path, so it
+   leaves `foo` and `bar` unset.  Attribute `baz` is set.
+
+3. Finally it examines `$GIT_DIR/info/attributes`.  This file
+   is used to override the in-tree settings.  The first line is
+   a match, and `foo` is set, `bar` is reverted to unspecified
+   state, and `baz` is unset.
+
+As the result, the attributes assignment to `t/abc` becomes:
+
+----------------------------------------------------------------
+foo	set to true
+bar	unspecified
+baz	set to false
+merge	set to string value "filfre"
+frotz	unspecified
+----------------------------------------------------------------

+NAME
+----
+gitcli - Git command-line interface and conventions
+
+SYNOPSIS
+--------
+gitcli
+
+
+DESCRIPTION
+-----------
+
+This manual describes the convention used throughout Git CLI.
+
+Many commands take revisions (most often "commits", but sometimes
+"tree-ish", depending on the context and command) and paths as their
+arguments.  Here are the rules:
+
+ * Revisions come first and then paths.
+   E.g. in `git diff v1.0 v2.0 arch/x86 include/asm-x86`,
+   `v1.0` and `v2.0` are revisions and `arch/x86` and `include/asm-x86`
+   are paths.
+
+ * When an argument can be misunderstood as either a revision or a path,
+   they can be disambiguated by placing `--` between them.
+   E.g. `git diff -- HEAD` is, "I have a file called HEAD in my work
+   tree.  Please show changes between the version I staged in the index
+   and what I have in the work tree for that file", not "show difference
+   between the HEAD commit and the work tree as a whole".  You can say
+   `git diff HEAD --` to ask for the latter.
+
+ * Without disambiguating `--`, Git makes a reasonable guess, but errors
+   out and asking you to disambiguate when ambiguous.  E.g. if you have a
+   file called HEAD in your work tree, `git diff HEAD` is ambiguous, and
+   you have to say either `git diff HEAD --` or `git diff -- HEAD` to
+   disambiguate.
++
+When writing a script that is expected to handle random user-input, it is
+a good practice to make it explicit which arguments are which by placing
+disambiguating `--` at appropriate places.
+
+ * Many commands allow wildcards in paths, but you need to protect
+   them from getting globbed by the shell.  These two mean different
+   things:
++
+--------------------------------
+$ git checkout -- *.c
+$ git checkout -- \*.c
+--------------------------------
++
+The former lets your shell expand the fileglob, and you are asking
+the dot-C files in your working tree to be overwritten with the version
+in the index.  The latter passes the `*.c` to Git, and you are asking
+the paths in the index that match the pattern to be checked out to your
+working tree.  After running `git add hello.c; rm hello.c`, you will _not_
+see `hello.c` in your working tree with the former, but with the latter
+you will.
+
+ * Just as the filesystem '.' (period) refers to the current directory,
+   using a '.' as a repository name in Git (a dot-repository) is a relative
+   path and means your current repository.
+
+Here are the rules regarding the "flags" that you should follow when you are
+scripting Git:
+
+ * it's preferred to use the non-dashed form of Git commands, which means that
+   you should prefer `git foo` to `git-foo`.
+
+ * splitting short options to separate words (prefer `git foo -a -b`
+   to `git foo -ab`, the latter may not even work).
+
+ * when a command-line option takes an argument, use the 'stuck' form.  In
+   other words, write `git foo -oArg` instead of `git foo -o Arg` for short
+   options, and `git foo --long-opt=Arg` instead of `git foo --long-opt Arg`
+   for long options.  An option that takes optional option-argument must be
+   written in the 'stuck' form.
+
+ * when you give a revision parameter to a command, make sure the parameter is
+   not ambiguous with a name of a file in the work tree.  E.g. do not write
+   `git log -1 HEAD` but write `git log -1 HEAD --`; the former will not work
+   if you happen to have a file called `HEAD` in the work tree.
+
+ * many commands allow a long option `--option` to be abbreviated
+   only to their unique prefix (e.g. if there is no other option
+   whose name begins with `opt`, you may be able to spell `--opt` to
+   invoke the `--option` flag), but you should fully spell them out
+   when writing your scripts; later versions of Git may introduce a
+   new option whose name shares the same prefix, e.g. `--optimize`,
+   to make a short prefix that used to be unique no longer unique.
+
+
+ENHANCED OPTION PARSER
+----------------------
+From the Git 1.5.4 series and further, many Git commands (not all of them at the
+time of the writing though) come with an enhanced option parser.
+
+Here is a list of the facilities provided by this option parser.
+
+
+Magic Options
+~~~~~~~~~~~~~
+Commands which have the enhanced option parser activated all understand a
+couple of magic command-line options:
+
+-h::
+	gives a pretty printed usage of the command.
++
+---------------------------------------------
+$ git describe -h
+usage: git describe [options] <commit-ish>*
+   or: git describe [options] --dirty
+
+    --contains            find the tag that comes after the commit
+    --debug               debug search strategy on stderr
+    --all                 use any ref
+    --tags                use any tag, even unannotated
+    --long                always use long format
+    --abbrev[=<n>]        use <n> digits to display SHA-1s
+---------------------------------------------
+
+--help-all::
+	Some Git commands take options that are only used for plumbing or that
+	are deprecated, and such options are hidden from the default usage. This
+	option gives the full list of options.
+
+
+Negating options
+~~~~~~~~~~~~~~~~
+Options with long option names can be negated by prefixing `--no-`. For
+example, `git branch` has the option `--track` which is 'on' by default. You
+can use `--no-track` to override that behaviour. The same goes for `--color`
+and `--no-color`.
+
+
+Aggregating short options
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Commands that support the enhanced option parser allow you to aggregate short
+options. This means that you can for example use `git rm -rf` or
+`git clean -fdx`.
+
+
+Abbreviating long options
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Commands that support the enhanced option parser accepts unique
+prefix of a long option as if it is fully spelled out, but use this
+with a caution.  For example, `git commit --amen` behaves as if you
+typed `git commit --amend`, but that is true only until a later version
+of Git introduces another option that shares the same prefix,
+e.g. `git commit --amenity` option.
+
+
+Separating argument from the option
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can write the mandatory option parameter to an option as a separate
+word on the command line.  That means that all the following uses work:
+
+----------------------------
+$ git foo --long-opt=Arg
+$ git foo --long-opt Arg
+$ git foo -oArg
+$ git foo -o Arg
+----------------------------
+
+However, this is *NOT* allowed for switches with an optional value, where the
+'stuck' form must be used:
+----------------------------
+$ git describe --abbrev HEAD     # correct
+$ git describe --abbrev=10 HEAD  # correct
+$ git describe --abbrev 10 HEAD  # NOT WHAT YOU MEANT
+----------------------------
+
+
+NOTES ON FREQUENTLY CONFUSED OPTIONS
+------------------------------------
+
+Many commands that can work on files in the working tree
+and/or in the index can take `--cached` and/or `--index`
+options.  Sometimes people incorrectly think that, because
+the index was originally called cache, these two are
+synonyms.  They are *not* -- these two options mean very
+different things.
+
+ * The `--cached` option is used to ask a command that
+   usually works on files in the working tree to *only* work
+   with the index.  For example, `git grep`, when used
+   without a commit to specify from which commit to look for
+   strings in, usually works on files in the working tree,
+   but with the `--cached` option, it looks for strings in
+   the index.
+
+ * The `--index` option is used to ask a command that
+   usually works on files in the working tree to *also*
+   affect the index.  For example, `git stash apply` usually
+   merges changes recorded in a stash to the working tree,
+   but with the `--index` option, it also merges changes to
+   the index as well.
+
+`git apply` command can be used with `--cached` and
+`--index` (but not at the same time).  Usually the command
+only affects the files in the working tree, but with
+`--index`, it patches both the files and their index
+entries, and with `--cached`, it modifies only the index
+entries.

+===================
+
+NAME
+----
+gitcore-tutorial - A Git core tutorial for developers
+
+SYNOPSIS
+--------
+git *
+
+DESCRIPTION
+-----------
+
+This tutorial explains how to use the "core" Git commands to set up and
+work with a Git repository.
+
+If you just need to use Git as a revision control system you may prefer
+to start with "A Tutorial Introduction to Git" (linkgit:gittutorial[7]) or
+link:user-manual.html[the Git User Manual].
+
+However, an understanding of these low-level tools can be helpful if
+you want to understand Git's internals.
+
+The core Git is often called "plumbing", with the prettier user
+interfaces on top of it called "porcelain". You may not want to use the
+plumbing directly very often, but it can be good to know what the
+plumbing does for when the porcelain isn't flushing.
+
+Back when this document was originally written, many porcelain
+commands were shell scripts. For simplicity, it still uses them as
+examples to illustrate how plumbing is fit together to form the
+porcelain commands. The source tree includes some of these scripts in
+contrib/examples/ for reference. Although these are not implemented as
+shell scripts anymore, the description of what the plumbing layer
+commands do is still valid.
+
+[NOTE]
+Deeper technical details are often marked as Notes, which you can
+skip on your first reading.
+
+
+Creating a Git repository
+-------------------------
+
+Creating a new Git repository couldn't be easier: all Git repositories start
+out empty, and the only thing you need to do is find yourself a
+subdirectory that you want to use as a working tree - either an empty
+one for a totally new project, or an existing working tree that you want
+to import into Git.
+
+For our first example, we're going to start a totally new repository from
+scratch, with no pre-existing files, and we'll call it 'git-tutorial'.
+To start up, create a subdirectory for it, change into that
+subdirectory, and initialize the Git infrastructure with 'git init':
+
+------------------------------------------------
+$ mkdir git-tutorial
+$ cd git-tutorial
+$ git init
+------------------------------------------------
+
+to which Git will reply
+
+----------------
+Initialized empty Git repository in .git/
+----------------
+
+which is just Git's way of saying that you haven't been doing anything
+strange, and that it will have created a local `.git` directory setup for
+your new project. You will now have a `.git` directory, and you can
+inspect that with 'ls'. For your new empty project, it should show you
+three entries, among other things:
+
+ - a file called `HEAD`, that has `ref: refs/heads/master` in it.
+   This is similar to a symbolic link and points at
+   `refs/heads/master` relative to the `HEAD` file.
++
+Don't worry about the fact that the file that the `HEAD` link points to
+doesn't even exist yet -- you haven't created the commit that will
+start your `HEAD` development branch yet.
+
+ - a subdirectory called `objects`, which will contain all the
+   objects of your project. You should never have any real reason to
+   look at the objects directly, but you might want to know that these
+   objects are what contains all the real 'data' in your repository.
+
+ - a subdirectory called `refs`, which contains references to objects.
+
+In particular, the `refs` subdirectory will contain two other
+subdirectories, named `heads` and `tags` respectively. They do
+exactly what their names imply: they contain references to any number
+of different 'heads' of development (aka 'branches'), and to any
+'tags' that you have created to name specific versions in your
+repository.
+
+One note: the special `master` head is the default branch, which is
+why the `.git/HEAD` file was created points to it even if it
+doesn't yet exist. Basically, the `HEAD` link is supposed to always
+point to the branch you are working on right now, and you always
+start out expecting to work on the `master` branch.
+
+However, this is only a convention, and you can name your branches
+anything you want, and don't have to ever even 'have' a `master`
+branch. A number of the Git tools will assume that `.git/HEAD` is
+valid, though.
+
+[NOTE]
+An 'object' is identified by its 160-bit SHA-1 hash, aka 'object name',
+and a reference to an object is always the 40-byte hex
+representation of that SHA-1 name. The files in the `refs`
+subdirectory are expected to contain these hex references
+(usually with a final `\n` at the end), and you should thus
+expect to see a number of 41-byte files containing these
+references in these `refs` subdirectories when you actually start
+populating your tree.
+
+[NOTE]
+An advanced user may want to take a look at linkgit:gitrepository-layout[5]
+after finishing this tutorial.
+
+You have now created your first Git repository. Of course, since it's
+empty, that's not very useful, so let's start populating it with data.
+
+
+Populating a Git repository
+---------------------------
+
+We'll keep this simple and stupid, so we'll start off with populating a
+few trivial files just to get a feel for it.
+
+Start off with just creating any random files that you want to maintain
+in your Git repository. We'll start off with a few bad examples, just to
+get a feel for how this works:
+
+------------------------------------------------
+$ echo "Hello World" >hello
+$ echo "Silly example" >example
+------------------------------------------------
+
+you have now created two files in your working tree (aka 'working directory'),
+but to actually check in your hard work, you will have to go through two steps:
+
+ - fill in the 'index' file (aka 'cache') with the information about your
+   working tree state.
+
+ - commit that index file as an object.
+
+The first step is trivial: when you want to tell Git about any changes
+to your working tree, you use the 'git update-index' program. That
+program normally just takes a list of filenames you want to update, but
+to avoid trivial mistakes, it refuses to add new entries to the index
+(or remove existing ones) unless you explicitly tell it that you're
+adding a new entry with the `--add` flag (or removing an entry with the
+`--remove`) flag.
+
+So to populate the index with the two files you just created, you can do
+
+------------------------------------------------
+$ git update-index --add hello example
+------------------------------------------------
+
+and you have now told Git to track those two files.
+
+In fact, as you did that, if you now look into your object directory,
+you'll notice that Git will have added two new objects to the object
+database. If you did exactly the steps above, you should now be able to do
+
+
+----------------
+$ ls .git/objects/??/*
+----------------
+
+and see two files:
+
+----------------
+.git/objects/55/7db03de997c86a4a028e1ebd3a1ceb225be238
+.git/objects/f2/4c74a2e500f5ee1332c86b94199f52b1d1d962
+----------------
+
+which correspond with the objects with names of `557db...` and
+`f24c7...` respectively.
+
+If you want to, you can use 'git cat-file' to look at those objects, but
+you'll have to use the object name, not the filename of the object:
+
+----------------
+$ git cat-file -t 557db03de997c86a4a028e1ebd3a1ceb225be238
+----------------
+
+where the `-t` tells 'git cat-file' to tell you what the "type" of the
+object is. Git will tell you that you have a "blob" object (i.e., just a
+regular file), and you can see the contents with
+
+----------------
+$ git cat-file blob 557db03
+----------------
+
+which will print out "Hello World". The object `557db03` is nothing
+more than the contents of your file `hello`.
+
+[NOTE]
+Don't confuse that object with the file `hello` itself. The
+object is literally just those specific *contents* of the file, and
+however much you later change the contents in file `hello`, the object
+we just looked at will never change. Objects are immutable.
+
+[NOTE]
+The second example demonstrates that you can
+abbreviate the object name to only the first several
+hexadecimal digits in most places.
+
+Anyway, as we mentioned previously, you normally never actually take a
+look at the objects themselves, and typing long 40-character hex
+names is not something you'd normally want to do. The above digression
+was just to show that 'git update-index' did something magical, and
+actually saved away the contents of your files into the Git object
+database.
+
+Updating the index did something else too: it created a `.git/index`
+file. This is the index that describes your current working tree, and
+something you should be very aware of. Again, you normally never worry
+about the index file itself, but you should be aware of the fact that
+you have not actually really "checked in" your files into Git so far,
+you've only *told* Git about them.
+
+However, since Git knows about them, you can now start using some of the
+most basic Git commands to manipulate the files or look at their status.
+
+In particular, let's not even check in the two files into Git yet, we'll
+start off by adding another line to `hello` first:
+
+------------------------------------------------
+$ echo "It's a new day for git" >>hello
+------------------------------------------------
+
+and you can now, since you told Git about the previous state of `hello`, ask
+Git what has changed in the tree compared to your old index, using the
+'git diff-files' command:
+
+------------
+$ git diff-files
+------------
+
+Oops. That wasn't very readable. It just spit out its own internal
+version of a 'diff', but that internal version really just tells you
+that it has noticed that "hello" has been modified, and that the old object
+contents it had have been replaced with something else.
+
+To make it readable, we can tell 'git diff-files' to output the
+differences as a patch, using the `-p` flag:
+
+------------
+$ git diff-files -p
+diff --git a/hello b/hello
+index 557db03..263414f 100644
+--- a/hello
++++ b/hello
+@@ -1 +1,2 @@
+ Hello World
++It's a new day for git
+------------
+
+i.e. the diff of the change we caused by adding another line to `hello`.
+
+In other words, 'git diff-files' always shows us the difference between
+what is recorded in the index, and what is currently in the working
+tree. That's very useful.
+
+A common shorthand for `git diff-files -p` is to just write `git
+diff`, which will do the same thing.
+
+------------
+$ git diff
+diff --git a/hello b/hello
+index 557db03..263414f 100644
+--- a/hello
++++ b/hello
+@@ -1 +1,2 @@
+ Hello World
++It's a new day for git
+------------
+
+
+Committing Git state
+--------------------
+
+Now, we want to go to the next stage in Git, which is to take the files
+that Git knows about in the index, and commit them as a real tree. We do
+that in two phases: creating a 'tree' object, and committing that 'tree'
+object as a 'commit' object together with an explanation of what the
+tree was all about, along with information of how we came to that state.
+
+Creating a tree object is trivial, and is done with 'git write-tree'.
+There are no options or other input: `git write-tree` will take the
+current index state, and write an object that describes that whole
+index. In other words, we're now tying together all the different
+filenames with their contents (and their permissions), and we're
+creating the equivalent of a Git "directory" object:
+
+------------------------------------------------
+$ git write-tree
+------------------------------------------------
+
+and this will just output the name of the resulting tree, in this case
+(if you have done exactly as I've described) it should be
+
+----------------
+8988da15d077d4829fc51d8544c097def6644dbb
+----------------
+
+which is another incomprehensible object name. Again, if you want to,
+you can use `git cat-file -t 8988d...` to see that this time the object
+is not a "blob" object, but a "tree" object (you can also use
+`git cat-file` to actually output the raw object contents, but you'll see
+mainly a binary mess, so that's less interesting).
+
+However -- normally you'd never use 'git write-tree' on its own, because
+normally you always commit a tree into a commit object using the
+'git commit-tree' command. In fact, it's easier to not actually use
+'git write-tree' on its own at all, but to just pass its result in as an
+argument to 'git commit-tree'.
+
+'git commit-tree' normally takes several arguments -- it wants to know
+what the 'parent' of a commit was, but since this is the first commit
+ever in this new repository, and it has no parents, we only need to pass in
+the object name of the tree. However, 'git commit-tree' also wants to get a
+commit message on its standard input, and it will write out the resulting
+object name for the commit to its standard output.
+
+And this is where we create the `.git/refs/heads/master` file
+which is pointed at by `HEAD`. This file is supposed to contain
+the reference to the top-of-tree of the master branch, and since
+that's exactly what 'git commit-tree' spits out, we can do this
+all with a sequence of simple shell commands:
+
+------------------------------------------------
+$ tree=$(git write-tree)
+$ commit=$(echo 'Initial commit' | git commit-tree $tree)
+$ git update-ref HEAD $commit
+------------------------------------------------
+
+In this case this creates a totally new commit that is not related to
+anything else. Normally you do this only *once* for a project ever, and
+all later commits will be parented on top of an earlier commit.
+
+Again, normally you'd never actually do this by hand. There is a
+helpful script called `git commit` that will do all of this for you. So
+you could have just written `git commit`
+instead, and it would have done the above magic scripting for you.
+
+
+Making a change
+---------------
+
+Remember how we did the 'git update-index' on file `hello` and then we
+changed `hello` afterward, and could compare the new state of `hello` with the
+state we saved in the index file?
+
+Further, remember how I said that 'git write-tree' writes the contents
+of the *index* file to the tree, and thus what we just committed was in
+fact the *original* contents of the file `hello`, not the new ones. We did
+that on purpose, to show the difference between the index state, and the
+state in the working tree, and how they don't have to match, even
+when we commit things.
+
+As before, if we do `git diff-files -p` in our git-tutorial project,
+we'll still see the same difference we saw last time: the index file
+hasn't changed by the act of committing anything. However, now that we
+have committed something, we can also learn to use a new command:
+'git diff-index'.
+
+Unlike 'git diff-files', which showed the difference between the index
+file and the working tree, 'git diff-index' shows the differences
+between a committed *tree* and either the index file or the working
+tree. In other words, 'git diff-index' wants a tree to be diffed
+against, and before we did the commit, we couldn't do that, because we
+didn't have anything to diff against.
+
+But now we can do
+
+----------------
+$ git diff-index -p HEAD
+----------------
+
+(where `-p` has the same meaning as it did in 'git diff-files'), and it
+will show us the same difference, but for a totally different reason.
+Now we're comparing the working tree not against the index file,
+but against the tree we just wrote. It just so happens that those two
+are obviously the same, so we get the same result.
+
+Again, because this is a common operation, you can also just shorthand
+it with
+
+----------------
+$ git diff HEAD
+----------------
+
+which ends up doing the above for you.
+
+In other words, 'git diff-index' normally compares a tree against the
+working tree, but when given the `--cached` flag, it is told to
+instead compare against just the index cache contents, and ignore the
+current working tree state entirely. Since we just wrote the index
+file to HEAD, doing `git diff-index --cached -p HEAD` should thus return
+an empty set of differences, and that's exactly what it does.
+
+[NOTE]
+================
+'git diff-index' really always uses the index for its
+comparisons, and saying that it compares a tree against the working
+tree is thus not strictly accurate. In particular, the list of
+files to compare (the "meta-data") *always* comes from the index file,
+regardless of whether the `--cached` flag is used or not. The `--cached`
+flag really only determines whether the file *contents* to be compared
+come from the working tree or not.
+
+This is not hard to understand, as soon as you realize that Git simply
+never knows (or cares) about files that it is not told about
+explicitly. Git will never go *looking* for files to compare, it
+expects you to tell it what the files are, and that's what the index
+is there for.
+================
+
+However, our next step is to commit the *change* we did, and again, to
+understand what's going on, keep in mind the difference between "working
+tree contents", "index file" and "committed tree". We have changes
+in the working tree that we want to commit, and we always have to
+work through the index file, so the first thing we need to do is to
+update the index cache:
+
+------------------------------------------------
+$ git update-index hello
+------------------------------------------------
+
+(note how we didn't need the `--add` flag this time, since Git knew
+about the file already).
+
+Note what happens to the different 'git diff-{asterisk}' versions here.
+After we've updated `hello` in the index, `git diff-files -p` now shows no
+differences, but `git diff-index -p HEAD` still *does* show that the
+current state is different from the state we committed. In fact, now
+'git diff-index' shows the same difference whether we use the `--cached`
+flag or not, since now the index is coherent with the working tree.
+
+Now, since we've updated `hello` in the index, we can commit the new
+version. We could do it by writing the tree by hand again, and
+committing the tree (this time we'd have to use the `-p HEAD` flag to
+tell commit that the HEAD was the *parent* of the new commit, and that
+this wasn't an initial commit any more), but you've done that once
+already, so let's just use the helpful script this time:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+which starts an editor for you to write the commit message and tells you
+a bit about what you have done.
+
+Write whatever message you want, and all the lines that start with '#'
+will be pruned out, and the rest will be used as the commit message for
+the change. If you decide you don't want to commit anything after all at
+this point (you can continue to edit things and update the index), you
+can just leave an empty message. Otherwise `git commit` will commit
+the change for you.
+
+You've now made your first real Git commit. And if you're interested in
+looking at what `git commit` really does, feel free to investigate:
+it's a few very simple shell scripts to generate the helpful (?) commit
+message headers, and a few one-liners that actually do the
+commit itself ('git commit').
+
+
+Inspecting Changes
+------------------
+
+While creating changes is useful, it's even more useful if you can tell
+later what changed. The most useful command for this is another of the
+'diff' family, namely 'git diff-tree'.
+
+'git diff-tree' can be given two arbitrary trees, and it will tell you the
+differences between them. Perhaps even more commonly, though, you can
+give it just a single commit object, and it will figure out the parent
+of that commit itself, and show the difference directly. Thus, to get
+the same diff that we've already seen several times, we can now do
+
+----------------
+$ git diff-tree -p HEAD
+----------------
+
+(again, `-p` means to show the difference as a human-readable patch),
+and it will show what the last commit (in `HEAD`) actually changed.
+
+[NOTE]

+Here is an ASCII art by Jon Loeliger that illustrates how
+various 'diff-{asterisk}' commands compare things.

+                    | Directory |
+                    +-----------+
+============
+
+More interestingly, you can also give 'git diff-tree' the `--pretty` flag,
+which tells it to also show the commit message and author and date of the
+commit, and you can tell it to show a whole series of diffs.
+Alternatively, you can tell it to be "silent", and not show the diffs at
+all, but just show the actual commit message.
+
+In fact, together with the 'git rev-list' program (which generates a
+list of revisions), 'git diff-tree' ends up being a veritable fount of
+changes.  You can emulate `git log`, `git log -p`, etc. with a trivial
+script that pipes the output of `git rev-list` to `git diff-tree --stdin`,
+which was exactly how early versions of `git log` were implemented.
+
+
+Tagging a version
+-----------------
+
+In Git, there are two kinds of tags, a "light" one, and an "annotated tag".
+
+A "light" tag is technically nothing more than a branch, except we put
+it in the `.git/refs/tags/` subdirectory instead of calling it a `head`.
+So the simplest form of tag involves nothing more than
+
+------------------------------------------------
+$ git tag my-first-tag
+------------------------------------------------
+
+which just writes the current `HEAD` into the `.git/refs/tags/my-first-tag`
+file, after which point you can then use this symbolic name for that
+particular state. You can, for example, do
+
+----------------
+$ git diff my-first-tag
+----------------
+
+to diff your current state against that tag which at this point will
+obviously be an empty diff, but if you continue to develop and commit
+stuff, you can use your tag as an "anchor-point" to see what has changed
+since you tagged it.
+
+An "annotated tag" is actually a real Git object, and contains not only a
+pointer to the state you want to tag, but also a small tag name and
+message, along with optionally a PGP signature that says that yes,
+you really did
+that tag. You create these annotated tags with either the `-a` or
+`-s` flag to 'git tag':
+
+----------------
+$ git tag -s <tagname>
+----------------
+
+which will sign the current `HEAD` (but you can also give it another
+argument that specifies the thing to tag, e.g., you could have tagged the
+current `mybranch` point by using `git tag <tagname> mybranch`).
+
+You normally only do signed tags for major releases or things
+like that, while the light-weight tags are useful for any marking you
+want to do -- any time you decide that you want to remember a certain
+point, just create a private tag for it, and you have a nice symbolic
+name for the state at that point.
+
+
+Copying repositories
+--------------------
+
+Git repositories are normally totally self-sufficient and relocatable.
+Unlike CVS, for example, there is no separate notion of
+"repository" and "working tree". A Git repository normally *is* the
+working tree, with the local Git information hidden in the `.git`
+subdirectory. There is nothing else. What you see is what you got.
+
+[NOTE]
+You can tell Git to split the Git internal information from
+the directory that it tracks, but we'll ignore that for now: it's not
+how normal projects work, and it's really only meant for special uses.
+So the mental model of "the Git information is always tied directly to
+the working tree that it describes" may not be technically 100%
+accurate, but it's a good model for all normal use.
+
+This has two implications:
+
+ - if you grow bored with the tutorial repository you created (or you've
+   made a mistake and want to start all over), you can just do simple
++
+----------------
+$ rm -rf git-tutorial
+----------------
++
+and it will be gone. There's no external repository, and there's no
+history outside the project you created.
+
+ - if you want to move or duplicate a Git repository, you can do so. There
+   is 'git clone' command, but if all you want to do is just to
+   create a copy of your repository (with all the full history that
+   went along with it), you can do so with a regular
+   `cp -a git-tutorial new-git-tutorial`.
++
+Note that when you've moved or copied a Git repository, your Git index
+file (which caches various information, notably some of the "stat"
+information for the files involved) will likely need to be refreshed.
+So after you do a `cp -a` to create a new copy, you'll want to do
++
+----------------
+$ git update-index --refresh
+----------------
++
+in the new repository to make sure that the index file is up-to-date.
+
+Note that the second point is true even across machines. You can
+duplicate a remote Git repository with *any* regular copy mechanism, be it
+'scp', 'rsync' or 'wget'.
+
+When copying a remote repository, you'll want to at a minimum update the
+index cache when you do this, and especially with other peoples'
+repositories you often want to make sure that the index cache is in some
+known state (you don't know *what* they've done and not yet checked in),
+so usually you'll precede the 'git update-index' with a
+
+----------------
+$ git read-tree --reset HEAD
+$ git update-index --refresh
+----------------
+
+which will force a total index re-build from the tree pointed to by `HEAD`.
+It resets the index contents to `HEAD`, and then the 'git update-index'
+makes sure to match up all index entries with the checked-out files.
+If the original repository had uncommitted changes in its
+working tree, `git update-index --refresh` notices them and
+tells you they need to be updated.
+
+The above can also be written as simply
+
+----------------
+$ git reset
+----------------
+
+and in fact a lot of the common Git command combinations can be scripted
+with the `git xyz` interfaces.  You can learn things by just looking
+at what the various git scripts do.  For example, `git reset` used to be
+the above two lines implemented in 'git reset', but some things like
+'git status' and 'git commit' are slightly more complex scripts around
+the basic Git commands.
+
+Many (most?) public remote repositories will not contain any of
+the checked out files or even an index file, and will *only* contain the
+actual core Git files. Such a repository usually doesn't even have the
+`.git` subdirectory, but has all the Git files directly in the
+repository.
+
+To create your own local live copy of such a "raw" Git repository, you'd
+first create your own subdirectory for the project, and then copy the
+raw repository contents into the `.git` directory. For example, to
+create your own copy of the Git repository, you'd do the following
+
+----------------
+$ mkdir my-git
+$ cd my-git
+$ rsync -rL rsync://rsync.kernel.org/pub/scm/git/git.git/ .git
+----------------
+
+followed by
+
+----------------
+$ git read-tree HEAD
+----------------
+
+to populate the index. However, now you have populated the index, and
+you have all the Git internal files, but you will notice that you don't
+actually have any of the working tree files to work on. To get
+those, you'd check them out with
+
+----------------
+$ git checkout-index -u -a
+----------------
+
+where the `-u` flag means that you want the checkout to keep the index
+up-to-date (so that you don't have to refresh it afterward), and the
+`-a` flag means "check out all files" (if you have a stale copy or an
+older version of a checked out tree you may also need to add the `-f`
+flag first, to tell 'git checkout-index' to *force* overwriting of any old
+files).
+
+Again, this can all be simplified with
+
+----------------
+$ git clone rsync://rsync.kernel.org/pub/scm/git/git.git/ my-git
+$ cd my-git
+$ git checkout
+----------------
+
+which will end up doing all of the above for you.
+
+You have now successfully copied somebody else's (mine) remote
+repository, and checked it out.
+
+
+Creating a new branch
+---------------------
+
+Branches in Git are really nothing more than pointers into the Git
+object database from within the `.git/refs/` subdirectory, and as we
+already discussed, the `HEAD` branch is nothing but a symlink to one of
+these object pointers.
+
+You can at any time create a new branch by just picking an arbitrary
+point in the project history, and just writing the SHA-1 name of that
+object into a file under `.git/refs/heads/`. You can use any filename you
+want (and indeed, subdirectories), but the convention is that the
+"normal" branch is called `master`. That's just a convention, though,
+and nothing enforces it.
+
+To show that as an example, let's go back to the git-tutorial repository we
+used earlier, and create a branch in it. You do that by simply just
+saying that you want to check out a new branch:
+
+------------
+$ git checkout -b mybranch
+------------
+
+will create a new branch based at the current `HEAD` position, and switch
+to it.
+
+[NOTE]
+================================================
+If you make the decision to start your new branch at some
+other point in the history than the current `HEAD`, you can do so by
+just telling 'git checkout' what the base of the checkout would be.
+In other words, if you have an earlier tag or branch, you'd just do
+
+------------
+$ git checkout -b mybranch earlier-commit
+------------
+
+and it would create the new branch `mybranch` at the earlier commit,
+and check out the state at that time.
+================================================
+
+You can always just jump back to your original `master` branch by doing
+
+------------
+$ git checkout master
+------------
+
+(or any other branch-name, for that matter) and if you forget which
+branch you happen to be on, a simple
+
+------------
+$ cat .git/HEAD
+------------
+
+will tell you where it's pointing.  To get the list of branches
+you have, you can say
+
+------------
+$ git branch
+------------
+
+which used to be nothing more than a simple script around `ls .git/refs/heads`.
+There will be an asterisk in front of the branch you are currently on.
+
+Sometimes you may wish to create a new branch _without_ actually
+checking it out and switching to it. If so, just use the command
+
+------------
+$ git branch <branchname> [startingpoint]
+------------
+
+which will simply _create_ the branch, but will not do anything further.
+You can then later -- once you decide that you want to actually develop
+on that branch -- switch to that branch with a regular 'git checkout'
+with the branchname as the argument.
+
+
+Merging two branches
+--------------------
+
+One of the ideas of having a branch is that you do some (possibly
+experimental) work in it, and eventually merge it back to the main
+branch. So assuming you created the above `mybranch` that started out
+being the same as the original `master` branch, let's make sure we're in
+that branch, and do some work there.
+
+------------------------------------------------
+$ git checkout mybranch
+$ echo "Work, work, work" >>hello
+$ git commit -m "Some work." -i hello
+------------------------------------------------
+
+Here, we just added another line to `hello`, and we used a shorthand for
+doing both `git update-index hello` and `git commit` by just giving the
+filename directly to `git commit`, with an `-i` flag (it tells
+Git to 'include' that file in addition to what you have done to
+the index file so far when making the commit).  The `-m` flag is to give the
+commit log message from the command line.
+
+Now, to make it a bit more interesting, let's assume that somebody else
+does some work in the original branch, and simulate that by going back
+to the master branch, and editing the same file differently there:
+
+------------
+$ git checkout master
+------------
+
+Here, take a moment to look at the contents of `hello`, and notice how they
+don't contain the work we just did in `mybranch` -- because that work
+hasn't happened in the `master` branch at all. Then do
+
+------------
+$ echo "Play, play, play" >>hello
+$ echo "Lots of fun" >>example
+$ git commit -m "Some fun." -i hello example
+------------
+
+since the master branch is obviously in a much better mood.
+
+Now, you've got two branches, and you decide that you want to merge the
+work done. Before we do that, let's introduce a cool graphical tool that
+helps you view what's going on:
+
+----------------
+$ gitk --all
+----------------
+
+will show you graphically both of your branches (that's what the `--all`
+means: normally it will just show you your current `HEAD`) and their
+histories. You can also see exactly how they came to be from a common
+source.
+
+Anyway, let's exit 'gitk' (`^Q` or the File menu), and decide that we want
+to merge the work we did on the `mybranch` branch into the `master`
+branch (which is currently our `HEAD` too). To do that, there's a nice
+script called 'git merge', which wants to know which branches you want
+to resolve and what the merge is all about:
+
+------------
+$ git merge -m "Merge work in mybranch" mybranch
+------------
+
+where the first argument is going to be used as the commit message if
+the merge can be resolved automatically.
+
+Now, in this case we've intentionally created a situation where the
+merge will need to be fixed up by hand, though, so Git will do as much
+of it as it can automatically (which in this case is just merge the `example`
+file, which had no differences in the `mybranch` branch), and say:
+
+----------------
+	Auto-merging hello
+	CONFLICT (content): Merge conflict in hello
+	Automatic merge failed; fix conflicts and then commit the result.
+----------------
+
+It tells you that it did an "Automatic merge", which
+failed due to conflicts in `hello`.
+
+Not to worry. It left the (trivial) conflict in `hello` in the same form you
+should already be well used to if you've ever used CVS, so let's just
+open `hello` in our editor (whatever that may be), and fix it up somehow.
+I'd suggest just making it so that `hello` contains all four lines:
+
+------------
+Hello World
+It's a new day for git
+Play, play, play
+Work, work, work
+------------
+
+and once you're happy with your manual merge, just do a
+
+------------
+$ git commit -i hello
+------------
+
+which will very loudly warn you that you're now committing a merge
+(which is correct, so never mind), and you can write a small merge
+message about your adventures in 'git merge'-land.
+
+After you're done, start up `gitk --all` to see graphically what the
+history looks like. Notice that `mybranch` still exists, and you can
+switch to it, and continue to work with it if you want to. The
+`mybranch` branch will not contain the merge, but next time you merge it
+from the `master` branch, Git will know how you merged it, so you'll not
+have to do _that_ merge again.
+
+Another useful tool, especially if you do not always work in X-Window
+environment, is `git show-branch`.
+
+------------------------------------------------
+$ git show-branch --topo-order --more=1 master mybranch
+* [master] Merge work in mybranch
+ ! [mybranch] Some work.
+--
+-  [master] Merge work in mybranch
+*+ [mybranch] Some work.
+*  [master^] Some fun.
+------------------------------------------------
+
+The first two lines indicate that it is showing the two branches
+with the titles of their top-of-the-tree commits, you are currently on
+`master` branch (notice the asterisk `*` character), and the first
+column for the later output lines is used to show commits contained in the
+`master` branch, and the second column for the `mybranch`
+branch. Three commits are shown along with their titles.
+All of them have non blank characters in the first column (`*`
+shows an ordinary commit on the current branch, `-` is a merge commit), which
+means they are now part of the `master` branch. Only the "Some
+work" commit has the plus `+` character in the second column,
+because `mybranch` has not been merged to incorporate these
+commits from the master branch.  The string inside brackets
+before the commit log message is a short name you can use to
+name the commit.  In the above example, 'master' and 'mybranch'
+are branch heads.  'master^' is the first parent of 'master'
+branch head.  Please see linkgit:gitrevisions[7] if you want to
+see more complex cases.
+
+[NOTE]
+Without the '--more=1' option, 'git show-branch' would not output the
+'[master^]' commit, as '[mybranch]' commit is a common ancestor of
+both 'master' and 'mybranch' tips.  Please see linkgit:git-show-branch[1]
+for details.
+
+[NOTE]
+If there were more commits on the 'master' branch after the merge, the
+merge commit itself would not be shown by 'git show-branch' by
+default.  You would need to provide '--sparse' option to make the
+merge commit visible in this case.
+
+Now, let's pretend you are the one who did all the work in
+`mybranch`, and the fruit of your hard work has finally been merged
+to the `master` branch. Let's go back to `mybranch`, and run
+'git merge' to get the "upstream changes" back to your branch.
+
+------------
+$ git checkout mybranch
+$ git merge -m "Merge upstream changes." master
+------------
+
+This outputs something like this (the actual commit object names
+would be different)
+
+----------------
+Updating from ae3a2da... to a80b4aa....
+Fast-forward (no commit created; -m option ignored)
+ example | 1 +
+ hello   | 1 +
+ 2 files changed, 2 insertions(+)
+----------------
+
+Because your branch did not contain anything more than what had
+already been merged into the `master` branch, the merge operation did
+not actually do a merge. Instead, it just updated the top of
+the tree of your branch to that of the `master` branch. This is
+often called 'fast-forward' merge.
+
+You can run `gitk --all` again to see how the commit ancestry
+looks like, or run 'show-branch', which tells you this.
+
+------------------------------------------------
+$ git show-branch master mybranch
+! [master] Merge work in mybranch
+ * [mybranch] Merge work in mybranch
+--
+-- [master] Merge work in mybranch
+------------------------------------------------
+
+
+Merging external work
+---------------------
+
+It's usually much more common that you merge with somebody else than
+merging with your own branches, so it's worth pointing out that Git
+makes that very easy too, and in fact, it's not that different from
+doing a 'git merge'. In fact, a remote merge ends up being nothing
+more than "fetch the work from a remote repository into a temporary tag"
+followed by a 'git merge'.
+
+Fetching from a remote repository is done by, unsurprisingly,
+'git fetch':
+
+----------------
+$ git fetch <remote-repository>
+----------------
+
+One of the following transports can be used to name the
+repository to download from:
+
+Rsync::
+	`rsync://remote.machine/path/to/repo.git/`
++
+Rsync transport is usable for both uploading and downloading,
+but is completely unaware of what git does, and can produce
+unexpected results when you download from the public repository
+while the repository owner is uploading into it via `rsync`
+transport.  Most notably, it could update the files under
+`refs/` which holds the object name of the topmost commits
+before uploading the files in `objects/` -- the downloader would
+obtain head commit object name while that object itself is still
+not available in the repository.  For this reason, it is
+considered deprecated.
+
+SSH::
+	`remote.machine:/path/to/repo.git/` or
++
+`ssh://remote.machine/path/to/repo.git/`
++
+This transport can be used for both uploading and downloading,
+and requires you to have a log-in privilege over `ssh` to the
+remote machine.  It finds out the set of objects the other side
+lacks by exchanging the head commits both ends have and
+transfers (close to) minimum set of objects.  It is by far the
+most efficient way to exchange Git objects between repositories.
+
+Local directory::
+	`/path/to/repo.git/`
++
+This transport is the same as SSH transport but uses 'sh' to run
+both ends on the local machine instead of running other end on
+the remote machine via 'ssh'.
+
+Git Native::
+	`git://remote.machine/path/to/repo.git/`
++
+This transport was designed for anonymous downloading.  Like SSH
+transport, it finds out the set of objects the downstream side
+lacks and transfers (close to) minimum set of objects.
+
+HTTP(S)::
+	`http://remote.machine/path/to/repo.git/`
++
+Downloader from http and https URL
+first obtains the topmost commit object name from the remote site
+by looking at the specified refname under `repo.git/refs/` directory,
+and then tries to obtain the
+commit object by downloading from `repo.git/objects/xx/xxx...`
+using the object name of that commit object.  Then it reads the
+commit object to find out its parent commits and the associate
+tree object; it repeats this process until it gets all the
+necessary objects.  Because of this behavior, they are
+sometimes also called 'commit walkers'.
++
+The 'commit walkers' are sometimes also called 'dumb
+transports', because they do not require any Git aware smart
+server like Git Native transport does.  Any stock HTTP server
+that does not even support directory index would suffice.  But
+you must prepare your repository with 'git update-server-info'
+to help dumb transport downloaders.
+
+Once you fetch from the remote repository, you `merge` that
+with your current branch.
+
+However -- it's such a common thing to `fetch` and then
+immediately `merge`, that it's called `git pull`, and you can
+simply do
+
+----------------
+$ git pull <remote-repository>
+----------------
+
+and optionally give a branch-name for the remote end as a second
+argument.
+
+[NOTE]
+You could do without using any branches at all, by
+keeping as many local repositories as you would like to have
+branches, and merging between them with 'git pull', just like
+you merge between branches. The advantage of this approach is
+that it lets you keep a set of files for each `branch` checked
+out and you may find it easier to switch back and forth if you
+juggle multiple lines of development simultaneously. Of
+course, you will pay the price of more disk usage to hold
+multiple working trees, but disk space is cheap these days.
+
+It is likely that you will be pulling from the same remote
+repository from time to time. As a short hand, you can store
+the remote repository URL in the local repository's config file
+like this:
+
+------------------------------------------------
+$ git config remote.linus.url http://www.kernel.org/pub/scm/git/git.git/
+------------------------------------------------
+
+and use the "linus" keyword with 'git pull' instead of the full URL.
+
+Examples.
+
+. `git pull linus`
+. `git pull linus tag v0.99.1`
+
+the above are equivalent to:

+
+How does the merge work?
+------------------------
+
+We said this tutorial shows what plumbing does to help you cope
+with the porcelain that isn't flushing, but we so far did not
+talk about how the merge really works.  If you are following
+this tutorial the first time, I'd suggest to skip to "Publishing
+your work" section and come back here later.
+
+OK, still with me?  To give us an example to look at, let's go
+back to the earlier repository with "hello" and "example" file,
+and bring ourselves back to the pre-merge state:
+
+------------
+$ git show-branch --more=2 master mybranch
+! [master] Merge work in mybranch
+ * [mybranch] Merge work in mybranch
+--
+-- [master] Merge work in mybranch
++* [master^2] Some work.
++* [master^] Some fun.
+------------
+
+Remember, before running 'git merge', our `master` head was at
+"Some fun." commit, while our `mybranch` head was at "Some
+work." commit.
+
+------------
+$ git checkout mybranch
+$ git reset --hard master^2
+$ git checkout master
+$ git reset --hard master^
+------------
+
+After rewinding, the commit structure should look like this:
+
+------------
+$ git show-branch
+* [master] Some fun.
+ ! [mybranch] Some work.
+--
+*  [master] Some fun.
+ + [mybranch] Some work.
+*+ [master^] Initial commit
+------------
+
+Now we are ready to experiment with the merge by hand.
+
+`git merge` command, when merging two branches, uses 3-way merge
+algorithm.  First, it finds the common ancestor between them.
+The command it uses is 'git merge-base':
+
+------------
+$ mb=$(git merge-base HEAD mybranch)
+------------
+
+The command writes the commit object name of the common ancestor
+to the standard output, so we captured its output to a variable,
+because we will be using it in the next step.  By the way, the common
+ancestor commit is the "Initial commit" commit in this case.  You can
+tell it by:
+
+------------
+$ git name-rev --name-only --tags $mb
+my-first-tag
+------------
+
+After finding out a common ancestor commit, the second step is
+this:
+
+------------
+$ git read-tree -m -u $mb HEAD mybranch
+------------
+
+This is the same 'git read-tree' command we have already seen,
+but it takes three trees, unlike previous examples.  This reads
+the contents of each tree into different 'stage' in the index
+file (the first tree goes to stage 1, the second to stage 2,
+etc.).  After reading three trees into three stages, the paths
+that are the same in all three stages are 'collapsed' into stage
+0.  Also paths that are the same in two of three stages are
+collapsed into stage 0, taking the SHA-1 from either stage 2 or
+stage 3, whichever is different from stage 1 (i.e. only one side
+changed from the common ancestor).
+
+After 'collapsing' operation, paths that are different in three
+trees are left in non-zero stages.  At this point, you can
+inspect the index file with this command:
+
+------------
+$ git ls-files --stage
+100644 7f8b141b65fdcee47321e399a2598a235a032422 0	example
+100644 557db03de997c86a4a028e1ebd3a1ceb225be238 1	hello
+100644 ba42a2a96e3027f3333e13ede4ccf4498c3ae942 2	hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
+------------
+
+In our example of only two files, we did not have unchanged
+files so only 'example' resulted in collapsing.  But in real-life
+large projects, when only a small number of files change in one commit,
+this 'collapsing' tends to trivially merge most of the paths
+fairly quickly, leaving only a handful of real changes in non-zero
+stages.
+
+To look at only non-zero stages, use `--unmerged` flag:
+
+------------
+$ git ls-files --unmerged
+100644 557db03de997c86a4a028e1ebd3a1ceb225be238 1	hello
+100644 ba42a2a96e3027f3333e13ede4ccf4498c3ae942 2	hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
+------------
+
+The next step of merging is to merge these three versions of the
+file, using 3-way merge.  This is done by giving
+'git merge-one-file' command as one of the arguments to
+'git merge-index' command:
+
+------------
+$ git merge-index git-merge-one-file hello
+Auto-merging hello
+ERROR: Merge conflict in hello
+fatal: merge program failed
+------------
+
+'git merge-one-file' script is called with parameters to
+describe those three versions, and is responsible to leave the
+merge results in the working tree.
+It is a fairly straightforward shell script, and
+eventually calls 'merge' program from RCS suite to perform a
+file-level 3-way merge.  In this case, 'merge' detects
+conflicts, and the merge result with conflict marks is left in
+the working tree..  This can be seen if you run `ls-files
+--stage` again at this point:
+
+------------
+$ git ls-files --stage
+100644 7f8b141b65fdcee47321e399a2598a235a032422 0	example
+100644 557db03de997c86a4a028e1ebd3a1ceb225be238 1	hello
+100644 ba42a2a96e3027f3333e13ede4ccf4498c3ae942 2	hello
+100644 cc44c73eb783565da5831b4d820c962954019b69 3	hello
+------------
+
+This is the state of the index file and the working file after
+'git merge' returns control back to you, leaving the conflicting
+merge for you to resolve.  Notice that the path `hello` is still
+unmerged, and what you see with 'git diff' at this point is
+differences since stage 2 (i.e. your version).
+
+
+Publishing your work
+--------------------
+
+So, we can use somebody else's work from a remote repository, but
+how can *you* prepare a repository to let other people pull from
+it?
+
+You do your real work in your working tree that has your
+primary repository hanging under it as its `.git` subdirectory.
+You *could* make that repository accessible remotely and ask
+people to pull from it, but in practice that is not the way
+things are usually done. A recommended way is to have a public
+repository, make it reachable by other people, and when the
+changes you made in your primary working tree are in good shape,
+update the public repository from it. This is often called
+'pushing'.
+
+[NOTE]
+This public repository could further be mirrored, and that is
+how Git repositories at `kernel.org` are managed.
+
+Publishing the changes from your local (private) repository to
+your remote (public) repository requires a write privilege on
+the remote machine. You need to have an SSH account there to
+run a single command, 'git-receive-pack'.
+
+First, you need to create an empty repository on the remote
+machine that will house your public repository. This empty
+repository will be populated and be kept up-to-date by pushing
+into it later. Obviously, this repository creation needs to be
+done only once.
+
+[NOTE]
+'git push' uses a pair of commands,
+'git send-pack' on your local machine, and 'git-receive-pack'
+on the remote machine. The communication between the two over
+the network internally uses an SSH connection.
+
+Your private repository's Git directory is usually `.git`, but
+your public repository is often named after the project name,
+i.e. `<project>.git`. Let's create such a public repository for
+project `my-git`. After logging into the remote machine, create
+an empty directory:
+
+------------
+$ mkdir my-git.git
+------------
+
+Then, make that directory into a Git repository by running
+'git init', but this time, since its name is not the usual
+`.git`, we do things slightly differently:
+
+------------
+$ GIT_DIR=my-git.git git init
+------------
+
+Make sure this directory is available for others you want your
+changes to be pulled via the transport of your choice. Also
+you need to make sure that you have the 'git-receive-pack'
+program on the `$PATH`.
+
+[NOTE]
+Many installations of sshd do not invoke your shell as the login
+shell when you directly run programs; what this means is that if
+your login shell is 'bash', only `.bashrc` is read and not
+`.bash_profile`. As a workaround, make sure `.bashrc` sets up
+`$PATH` so that you can run 'git-receive-pack' program.
+
+[NOTE]
+If you plan to publish this repository to be accessed over http,
+you should do `mv my-git.git/hooks/post-update.sample
+my-git.git/hooks/post-update` at this point.
+This makes sure that every time you push into this
+repository, `git update-server-info` is run.
+
+Your "public repository" is now ready to accept your changes.
+Come back to the machine you have your private repository. From
+there, run this command:
+
+------------
+$ git push <public-host>:/path/to/my-git.git master
+------------
+
+This synchronizes your public repository to match the named
+branch head (i.e. `master` in this case) and objects reachable
+from them in your current repository.
+
+As a real example, this is how I update my public Git
+repository. Kernel.org mirror network takes care of the
+propagation to other publicly visible machines:
+
+------------
+$ git push master.kernel.org:/pub/scm/git/git.git/
+------------
+
+
+Packing your repository
+-----------------------
+
+Earlier, we saw that one file under `.git/objects/??/` directory
+is stored for each Git object you create. This representation
+is efficient to create atomically and safely, but
+not so convenient to transport over the network. Since Git objects are
+immutable once they are created, there is a way to optimize the
+storage by "packing them together". The command
+
+------------
+$ git repack
+------------
+
+will do it for you. If you followed the tutorial examples, you
+would have accumulated about 17 objects in `.git/objects/??/`
+directories by now. 'git repack' tells you how many objects it
+packed, and stores the packed file in `.git/objects/pack`
+directory.
+
+[NOTE]
+You will see two files, `pack-*.pack` and `pack-*.idx`,
+in `.git/objects/pack` directory. They are closely related to
+each other, and if you ever copy them by hand to a different
+repository for whatever reason, you should make sure you copy
+them together. The former holds all the data from the objects
+in the pack, and the latter holds the index for random
+access.
+
+If you are paranoid, running 'git verify-pack' command would
+detect if you have a corrupt pack, but do not worry too much.
+Our programs are always perfect ;-).
+
+Once you have packed objects, you do not need to leave the
+unpacked objects that are contained in the pack file anymore.
+
+------------
+$ git prune-packed
+------------
+
+would remove them for you.
+
+You can try running `find .git/objects -type f` before and after
+you run `git prune-packed` if you are curious.  Also `git
+count-objects` would tell you how many unpacked objects are in
+your repository and how much space they are consuming.
+
+[NOTE]
+`git pull` is slightly cumbersome for HTTP transport, as a
+packed repository may contain relatively few objects in a
+relatively large pack. If you expect many HTTP pulls from your
+public repository you might want to repack & prune often, or
+never.
+
+If you run `git repack` again at this point, it will say
+"Nothing new to pack.". Once you continue your development and
+accumulate the changes, running `git repack` again will create a
+new pack, that contains objects created since you packed your
+repository the last time. We recommend that you pack your project
+soon after the initial import (unless you are starting your
+project from scratch), and then run `git repack` every once in a
+while, depending on how active your project is.
+
+When a repository is synchronized via `git push` and `git pull`
+objects packed in the source repository are usually stored
+unpacked in the destination, unless rsync transport is used.
+While this allows you to use different packing strategies on
+both ends, it also means you may need to repack both
+repositories every once in a while.
+
+
+Working with Others
+-------------------
+
+Although Git is a truly distributed system, it is often
+convenient to organize your project with an informal hierarchy
+of developers. Linux kernel development is run this way. There
+is a nice illustration (page 17, "Merges to Mainline") in
+http://www.xenotime.net/linux/mentor/linux-mentoring-2006.pdf[Randy Dunlap's presentation].
+
+It should be stressed that this hierarchy is purely *informal*.
+There is nothing fundamental in Git that enforces the "chain of
+patch flow" this hierarchy implies. You do not have to pull
+from only one remote repository.
+
+A recommended workflow for a "project lead" goes like this:
+
+1. Prepare your primary repository on your local machine. Your
+   work is done there.
+
+2. Prepare a public repository accessible to others.
++
+If other people are pulling from your repository over dumb
+transport protocols (HTTP), you need to keep this repository
+'dumb transport friendly'.  After `git init`,
+`$GIT_DIR/hooks/post-update.sample` copied from the standard templates
+would contain a call to 'git update-server-info'
+but you need to manually enable the hook with
+`mv post-update.sample post-update`.  This makes sure
+'git update-server-info' keeps the necessary files up-to-date.
+
+3. Push into the public repository from your primary
+   repository.
+
+4. 'git repack' the public repository. This establishes a big
+   pack that contains the initial set of objects as the
+   baseline, and possibly 'git prune' if the transport
+   used for pulling from your repository supports packed
+   repositories.
+
+5. Keep working in your primary repository. Your changes
+   include modifications of your own, patches you receive via
+   e-mails, and merges resulting from pulling the "public"
+   repositories of your "subsystem maintainers".
++
+You can repack this private repository whenever you feel like.
+
+6. Push your changes to the public repository, and announce it
+   to the public.
+
+7. Every once in a while, 'git repack' the public repository.
+   Go back to step 5. and continue working.
+
+
+A recommended work cycle for a "subsystem maintainer" who works
+on that project and has an own "public repository" goes like this:
+
+1. Prepare your work repository, by 'git clone' the public
+   repository of the "project lead". The URL used for the
+   initial cloning is stored in the remote.origin.url
+   configuration variable.
+
+2. Prepare a public repository accessible to others, just like
+   the "project lead" person does.
+
+3. Copy over the packed files from "project lead" public
+   repository to your public repository, unless the "project
+   lead" repository lives on the same machine as yours.  In the
+   latter case, you can use `objects/info/alternates` file to
+   point at the repository you are borrowing from.
+
+4. Push into the public repository from your primary
+   repository. Run 'git repack', and possibly 'git prune' if the
+   transport used for pulling from your repository supports
+   packed repositories.
+
+5. Keep working in your primary repository. Your changes
+   include modifications of your own, patches you receive via
+   e-mails, and merges resulting from pulling the "public"
+   repositories of your "project lead" and possibly your
+   "sub-subsystem maintainers".
++
+You can repack this private repository whenever you feel
+like.
+
+6. Push your changes to your public repository, and ask your
+   "project lead" and possibly your "sub-subsystem
+   maintainers" to pull from it.
+
+7. Every once in a while, 'git repack' the public repository.
+   Go back to step 5. and continue working.
+
+
+A recommended work cycle for an "individual developer" who does
+not have a "public" repository is somewhat different. It goes
+like this:
+
+1. Prepare your work repository, by 'git clone' the public
+   repository of the "project lead" (or a "subsystem
+   maintainer", if you work on a subsystem). The URL used for
+   the initial cloning is stored in the remote.origin.url
+   configuration variable.
+
+2. Do your work in your repository on 'master' branch.
+
+3. Run `git fetch origin` from the public repository of your
+   upstream every once in a while. This does only the first
+   half of `git pull` but does not merge. The head of the
+   public repository is stored in `.git/refs/remotes/origin/master`.
+
+4. Use `git cherry origin` to see which ones of your patches
+   were accepted, and/or use `git rebase origin` to port your
+   unmerged changes forward to the updated upstream.
+
+5. Use `git format-patch origin` to prepare patches for e-mail
+   submission to your upstream and send it out. Go back to
+   step 2. and continue.
+
+
+Working with Others, Shared Repository Style
+--------------------------------------------
+
+If you are coming from CVS background, the style of cooperation
+suggested in the previous section may be new to you. You do not
+have to worry. Git supports "shared public repository" style of
+cooperation you are probably more familiar with as well.
+
+See linkgit:gitcvs-migration[7] for the details.
+
+Bundling your work together
+---------------------------
+
+It is likely that you will be working on more than one thing at
+a time.  It is easy to manage those more-or-less independent tasks
+using branches with Git.
+
+We have already seen how branches work previously,
+with "fun and work" example using two branches.  The idea is the
+same if there are more than two branches.  Let's say you started
+out from "master" head, and have some new code in the "master"
+branch, and two independent fixes in the "commit-fix" and
+"diff-fix" branches:
+
+------------
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+  * [master] Release candidate #1
+---
+ +  [diff-fix] Fix rename detection.
+ +  [diff-fix~1] Better common substring algorithm.
++   [commit-fix] Fix commit message normalization.
+  * [master] Release candidate #1
+++* [diff-fix~2] Pretty-print messages.
+------------
+
+Both fixes are tested well, and at this point, you want to merge
+in both of them.  You could merge in 'diff-fix' first and then
+'commit-fix' next, like this:
+
+------------
+$ git merge -m "Merge fix in diff-fix" diff-fix
+$ git merge -m "Merge fix in commit-fix" commit-fix
+------------
+
+Which would result in:
+
+------------
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+  * [master] Merge fix in commit-fix
+---
+  - [master] Merge fix in commit-fix
++ * [commit-fix] Fix commit message normalization.
+  - [master~1] Merge fix in diff-fix
+ +* [diff-fix] Fix rename detection.
+ +* [diff-fix~1] Better common substring algorithm.
+  * [master~2] Release candidate #1
+++* [master~3] Pretty-print messages.
+------------
+
+However, there is no particular reason to merge in one branch
+first and the other next, when what you have are a set of truly
+independent changes (if the order mattered, then they are not
+independent by definition).  You could instead merge those two
+branches into the current branch at once.  First let's undo what
+we just did and start over.  We would want to get the master
+branch before these two merges by resetting it to 'master~2':
+
+------------
+$ git reset --hard master~2
+------------
+
+You can make sure `git show-branch` matches the state before
+those two 'git merge' you just did.  Then, instead of running
+two 'git merge' commands in a row, you would merge these two
+branch heads (this is known as 'making an Octopus'):
+
+------------
+$ git merge commit-fix diff-fix
+$ git show-branch
+! [commit-fix] Fix commit message normalization.
+ ! [diff-fix] Fix rename detection.
+  * [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
+---
+  - [master] Octopus merge of branches 'diff-fix' and 'commit-fix'
++ * [commit-fix] Fix commit message normalization.
+ +* [diff-fix] Fix rename detection.
+ +* [diff-fix~1] Better common substring algorithm.
+  * [master~1] Release candidate #1
+++* [master~2] Pretty-print messages.
+------------
+
+Note that you should not do Octopus because you can.  An octopus
+is a valid thing to do and often makes it easier to view the
+commit history if you are merging more than two independent
+changes at the same time.  However, if you have merge conflicts
+with any of the branches you are merging in and need to hand
+resolve, that is an indication that the development happened in
+those branches were not independent after all, and you should
+merge two at a time, documenting how you resolved the conflicts,
+and the reason why you preferred changes made in one side over
+the other.  Otherwise it would make the project history harder
+to follow, not easier.

+=================
+
+NAME
+----
+gitcredentials - providing usernames and passwords to Git
+
+SYNOPSIS
+--------
+------------------
+git config credential.https://example.com.username myusername
+git config credential.helper "$helper $options"
+------------------
+
+DESCRIPTION
+-----------
+
+Git will sometimes need credentials from the user in order to perform
+operations; for example, it may need to ask for a username and password
+in order to access a remote repository over HTTP. This manual describes
+the mechanisms Git uses to request these credentials, as well as some
+features to avoid inputting these credentials repeatedly.
+
+REQUESTING CREDENTIALS
+----------------------
+
+Without any credential helpers defined, Git will try the following
+strategies to ask the user for usernames and passwords:
+
+1. If the `GIT_ASKPASS` environment variable is set, the program
+   specified by the variable is invoked. A suitable prompt is provided
+   to the program on the command line, and the user's input is read
+   from its standard output.
+
+2. Otherwise, if the `core.askPass` configuration variable is set, its
+   value is used as above.
+
+3. Otherwise, if the `SSH_ASKPASS` environment variable is set, its
+   value is used as above.
+
+4. Otherwise, the user is prompted on the terminal.
+
+AVOIDING REPETITION
+-------------------
+
+It can be cumbersome to input the same credentials over and over.  Git
+provides two methods to reduce this annoyance:
+
+1. Static configuration of usernames for a given authentication context.
+
+2. Credential helpers to cache or store passwords, or to interact with
+   a system password wallet or keychain.
+
+The first is simple and appropriate if you do not have secure storage available
+for a password. It is generally configured by adding this to your config:
+
+---------------------------------------
+[credential "https://example.com"]
+	username = me
+---------------------------------------
+
+Credential helpers, on the other hand, are external programs from which Git can
+request both usernames and passwords; they typically interface with secure
+storage provided by the OS or other programs.
+
+To use a helper, you must first select one to use. Git currently
+includes the following helpers:
+
+cache::
+
+	Cache credentials in memory for a short period of time. See
+	linkgit:git-credential-cache[1] for details.
+
+store::
+
+	Store credentials indefinitely on disk. See
+	linkgit:git-credential-store[1] for details.
+
+You may also have third-party helpers installed; search for
+`credential-*` in the output of `git help -a`, and consult the
+documentation of individual helpers.  Once you have selected a helper,
+you can tell Git to use it by putting its name into the
+credential.helper variable.
+
+1. Find a helper.
++
+-------------------------------------------
+$ git help -a | grep credential-
+credential-foo
+-------------------------------------------
+
+2. Read its description.
++
+-------------------------------------------
+$ git help credential-foo
+-------------------------------------------
+
+3. Tell Git to use it.
++
+-------------------------------------------
+$ git config --global credential.helper foo
+-------------------------------------------
+
+If there are multiple instances of the `credential.helper` configuration
+variable, each helper will be tried in turn, and may provide a username,
+password, or nothing. Once Git has acquired both a username and a
+password, no more helpers will be tried.
+
+
+CREDENTIAL CONTEXTS
+-------------------
+
+Git considers each credential to have a context defined by a URL. This context
+is used to look up context-specific configuration, and is passed to any
+helpers, which may use it as an index into secure storage.
+
+For instance, imagine we are accessing `https://example.com/foo.git`. When Git
+looks into a config file to see if a section matches this context, it will
+consider the two a match if the context is a more-specific subset of the
+pattern in the config file. For example, if you have this in your config file:
+
+--------------------------------------
+[credential "https://example.com"]
+	username = foo
+--------------------------------------
+
+then we will match: both protocols are the same, both hosts are the same, and
+the "pattern" URL does not care about the path component at all. However, this
+context would not match:
+
+--------------------------------------
+[credential "https://kernel.org"]
+	username = foo
+--------------------------------------
+
+because the hostnames differ. Nor would it match `foo.example.com`; Git
+compares hostnames exactly, without considering whether two hosts are part of
+the same domain. Likewise, a config entry for `http://example.com` would not
+match: Git compares the protocols exactly.
+
+
+CONFIGURATION OPTIONS
+---------------------
+
+Options for a credential context can be configured either in
+`credential.*` (which applies to all credentials), or
+`credential.<url>.*`, where <url> matches the context as described
+above.
+
+The following options are available in either location:
+
+helper::
+
+	The name of an external credential helper, and any associated options.
+	If the helper name is not an absolute path, then the string `git
+	credential-` is prepended. The resulting string is executed by the
+	shell (so, for example, setting this to `foo --option=bar` will execute
+	`git credential-foo --option=bar` via the shell. See the manual of
+	specific helpers for examples of their use.
+
+username::
+
+	A default username, if one is not provided in the URL.
+
+useHttpPath::
+
+	By default, Git does not consider the "path" component of an http URL
+	to be worth matching via external helpers. This means that a credential
+	stored for `https://example.com/foo.git` will also be used for
+	`https://example.com/bar.git`. If you do want to distinguish these
+	cases, set this option to `true`.
+
+
+CUSTOM HELPERS
+--------------
+
+You can write your own custom helpers to interface with any system in
+which you keep credentials. See the documentation for Git's
+link:technical/api-credentials.html[credentials API] for details.

+gitcvs-migration(7)
+===================
+
+NAME
+----
+gitcvs-migration - Git for CVS users
+
+SYNOPSIS
+--------
+[verse]
+'git cvsimport' *
+
+DESCRIPTION
+-----------
+
+Git differs from CVS in that every working tree contains a repository with
+a full copy of the project history, and no repository is inherently more
+important than any other.  However, you can emulate the CVS model by
+designating a single shared repository which people can synchronize with;
+this document explains how to do that.
+
+Some basic familiarity with Git is required. Having gone through
+linkgit:gittutorial[7] and
+linkgit:gitglossary[7] should be sufficient.
+
+Developing against a shared repository
+--------------------------------------
+
+Suppose a shared repository is set up in /pub/repo.git on the host
+foo.com.  Then as an individual committer you can clone the shared
+repository over ssh with:
+
+------------------------------------------------
+$ git clone foo.com:/pub/repo.git/ my-project
+$ cd my-project
+------------------------------------------------
+
+and hack away.  The equivalent of 'cvs update' is
+
+------------------------------------------------
+$ git pull origin
+------------------------------------------------
+
+which merges in any work that others might have done since the clone
+operation.  If there are uncommitted changes in your working tree, commit
+them first before running git pull.
+
+[NOTE]
+================================
+The 'pull' command knows where to get updates from because of certain
+configuration variables that were set by the first 'git clone'
+command; see `git config -l` and the linkgit:git-config[1] man
+page for details.
+================================
+
+You can update the shared repository with your changes by first committing
+your changes, and then using the 'git push' command:
+
+------------------------------------------------
+$ git push origin master
+------------------------------------------------
+
+to "push" those commits to the shared repository.  If someone else has
+updated the repository more recently, 'git push', like 'cvs commit', will
+complain, in which case you must pull any changes before attempting the
+push again.
+
+In the 'git push' command above we specify the name of the remote branch
+to update (`master`).  If we leave that out, 'git push' tries to update
+any branches in the remote repository that have the same name as a branch
+in the local repository.  So the last 'push' can be done with either of:
+
+------------
+$ git push origin
+$ git push foo.com:/pub/project.git/
+------------
+
+as long as the shared repository does not have any branches
+other than `master`.
+
+Setting Up a Shared Repository
+------------------------------
+
+We assume you have already created a Git repository for your project,
+possibly created from scratch or from a tarball (see
+linkgit:gittutorial[7]), or imported from an already existing CVS
+repository (see the next section).
+
+Assume your existing repo is at /home/alice/myproject.  Create a new "bare"
+repository (a repository without a working tree) and fetch your project into
+it:
+
+------------------------------------------------
+$ mkdir /pub/my-repo.git
+$ cd /pub/my-repo.git
+$ git --bare init --shared
+$ git --bare fetch /home/alice/myproject master:master
+------------------------------------------------
+
+Next, give every team member read/write access to this repository.  One
+easy way to do this is to give all the team members ssh access to the
+machine where the repository is hosted.  If you don't want to give them a
+full shell on the machine, there is a restricted shell which only allows
+users to do Git pushes and pulls; see linkgit:git-shell[1].
+
+Put all the committers in the same group, and make the repository
+writable by that group:
+
+------------------------------------------------
+$ chgrp -R $group /pub/my-repo.git
+------------------------------------------------
+
+Make sure committers have a umask of at most 027, so that the directories
+they create are writable and searchable by other group members.
+
+Importing a CVS archive
+-----------------------
+
+First, install version 2.1 or higher of cvsps from
+http://www.cobite.com/cvsps/[http://www.cobite.com/cvsps/] and make
+sure it is in your path.  Then cd to a checked out CVS working directory
+of the project you are interested in and run linkgit:git-cvsimport[1]:
+
+-------------------------------------------
+$ git cvsimport -C <destination> <module>
+-------------------------------------------
+
+This puts a Git archive of the named CVS module in the directory
+<destination>, which will be created if necessary.
+
+The import checks out from CVS every revision of every file.  Reportedly
+cvsimport can average some twenty revisions per second, so for a
+medium-sized project this should not take more than a couple of minutes.
+Larger projects or remote repositories may take longer.
+
+The main trunk is stored in the Git branch named `origin`, and additional
+CVS branches are stored in Git branches with the same names.  The most
+recent version of the main trunk is also left checked out on the `master`
+branch, so you can start adding your own changes right away.
+
+The import is incremental, so if you call it again next month it will
+fetch any CVS updates that have been made in the meantime.  For this to
+work, you must not modify the imported branches; instead, create new
+branches for your own changes, and merge in the imported branches as
+necessary.
+
+If you want a shared repository, you will need to make a bare clone
+of the imported directory, as described above. Then treat the imported
+directory as another development clone for purposes of merging
+incremental imports.
+
+Advanced Shared Repository Management
+-------------------------------------
+
+Git allows you to specify scripts called "hooks" to be run at certain
+points.  You can use these, for example, to send all commits to the shared
+repository to a mailing list.  See linkgit:githooks[5].
+
+You can enforce finer grained permissions using update hooks.  See
+link:howto/update-hook-example.html[Controlling access to branches using
+update hooks].
+
+Providing CVS Access to a Git Repository
+----------------------------------------
+
+It is also possible to provide true CVS access to a Git repository, so
+that developers can still use CVS; see linkgit:git-cvsserver[1] for
+details.
+
+Alternative Development Models
+------------------------------
+
+CVS users are accustomed to giving a group of developers commit access to
+a common repository.  As we've seen, this is also possible with Git.
+However, the distributed nature of Git allows other development models,
+and you may want to first consider whether one of them might be a better
+fit for your project.
+
+For example, you can choose a single person to maintain the project's
+primary public repository.  Other developers then clone this repository
+and each work in their own clone.  When they have a series of changes that
+they're happy with, they ask the maintainer to pull from the branch
+containing the changes.  The maintainer reviews their changes and pulls
+them into the primary repository, which other developers pull from as
+necessary to stay coordinated.  The Linux kernel and other projects use
+variants of this model.
+
+With a small group, developers may just pull changes from each other's
+repositories without the need for a central maintainer.

+
+NAME
+----
+gitdiffcore - Tweaking diff output
+
+SYNOPSIS
+--------
+[verse]
+'git diff' *
+
+DESCRIPTION
+-----------
+
+The diff commands 'git diff-index', 'git diff-files', and 'git diff-tree'
+can be told to manipulate differences they find in
+unconventional ways before showing 'diff' output.  The manipulation
+is collectively called "diffcore transformation".  This short note
+describes what they are and how to use them to produce 'diff' output
+that is easier to understand than the conventional kind.
+
+
+The chain of operation
+----------------------
+
+The 'git diff-{asterisk}' family works by first comparing two sets of
+files:
+
+ - 'git diff-index' compares contents of a "tree" object and the
+   working directory (when '--cached' flag is not used) or a
+   "tree" object and the index file (when '--cached' flag is
+   used);
+
+ - 'git diff-files' compares contents of the index file and the
+   working directory;
+
+ - 'git diff-tree' compares contents of two "tree" objects;
+
+In all of these cases, the commands themselves first optionally limit
+the two sets of files by any pathspecs given on their command-lines,
+and compare corresponding paths in the two resulting sets of files.
+
+The pathspecs are used to limit the world diff operates in.  They remove
+the filepairs outside the specified sets of pathnames.  E.g. If the
+input set of filepairs included:
+
+------------------------------------------------
+:100644 100644 bcd1234... 0123456... M junkfile
+------------------------------------------------
+
+but the command invocation was `git diff-files myfile`, then the
+junkfile entry would be removed from the list because only "myfile"
+is under consideration.
+
+The result of comparison is passed from these commands to what is
+internally called "diffcore", in a format similar to what is output
+when the -p option is not used.  E.g.
+
+------------------------------------------------
+in-place edit  :100644 100644 bcd1234... 0123456... M file0
+create         :000000 100644 0000000... 1234567... A file4
+delete         :100644 000000 1234567... 0000000... D file5
+unmerged       :000000 000000 0000000... 0000000... U file6
+------------------------------------------------
+
+The diffcore mechanism is fed a list of such comparison results
+(each of which is called "filepair", although at this point each
+of them talks about a single file), and transforms such a list
+into another list.  There are currently 5 such transformations:
+
+- diffcore-break
+- diffcore-rename
+- diffcore-merge-broken
+- diffcore-pickaxe
+- diffcore-order
+
+These are applied in sequence.  The set of filepairs 'git diff-{asterisk}'
+commands find are used as the input to diffcore-break, and
+the output from diffcore-break is used as the input to the
+next transformation.  The final result is then passed to the
+output routine and generates either diff-raw format (see Output
+format sections of the manual for 'git diff-{asterisk}' commands) or
+diff-patch format.
+
+
+diffcore-break: For Splitting Up "Complete Rewrites"
+----------------------------------------------------
+
+The second transformation in the chain is diffcore-break, and is
+controlled by the -B option to the 'git diff-{asterisk}' commands.  This is
+used to detect a filepair that represents "complete rewrite" and
+break such filepair into two filepairs that represent delete and
+create.  E.g.  If the input contained this filepair:
+
+------------------------------------------------
+:100644 100644 bcd1234... 0123456... M file0
+------------------------------------------------
+
+and if it detects that the file "file0" is completely rewritten,
+it changes it to:
+
+------------------------------------------------
+:100644 000000 bcd1234... 0000000... D file0
+:000000 100644 0000000... 0123456... A file0
+------------------------------------------------
+
+For the purpose of breaking a filepair, diffcore-break examines
+the extent of changes between the contents of the files before
+and after modification (i.e. the contents that have "bcd1234..."
+and "0123456..." as their SHA-1 content ID, in the above
+example).  The amount of deletion of original contents and
+insertion of new material are added together, and if it exceeds
+the "break score", the filepair is broken into two.  The break
+score defaults to 50% of the size of the smaller of the original
+and the result (i.e. if the edit shrinks the file, the size of
+the result is used; if the edit lengthens the file, the size of
+the original is used), and can be customized by giving a number
+after "-B" option (e.g. "-B75" to tell it to use 75%).
+
+
+diffcore-rename: For Detection Renames and Copies
+-------------------------------------------------
+
+This transformation is used to detect renames and copies, and is
+controlled by the -M option (to detect renames) and the -C option
+(to detect copies as well) to the 'git diff-{asterisk}' commands.  If the
+input contained these filepairs:
+
+------------------------------------------------
+:100644 000000 0123456... 0000000... D fileX
+:000000 100644 0000000... 0123456... A file0
+------------------------------------------------
+
+and the contents of the deleted file fileX is similar enough to
+the contents of the created file file0, then rename detection
+merges these filepairs and creates:
+
+------------------------------------------------
+:100644 100644 0123456... 0123456... R100 fileX file0
+------------------------------------------------
+
+When the "-C" option is used, the original contents of modified files,
+and deleted files (and also unmodified files, if the
+"--find-copies-harder" option is used) are considered as candidates
+of the source files in rename/copy operation.  If the input were like
+these filepairs, that talk about a modified file fileY and a newly
+created file file0:
+
+------------------------------------------------
+:100644 100644 0123456... 1234567... M fileY
+:000000 100644 0000000... bcd3456... A file0
+------------------------------------------------
+
+the original contents of fileY and the resulting contents of
+file0 are compared, and if they are similar enough, they are
+changed to:
+
+------------------------------------------------
+:100644 100644 0123456... 1234567... M fileY
+:100644 100644 0123456... bcd3456... C100 fileY file0
+------------------------------------------------
+
+In both rename and copy detection, the same "extent of changes"
+algorithm used in diffcore-break is used to determine if two
+files are "similar enough", and can be customized to use
+a similarity score different from the default of 50% by giving a
+number after the "-M" or "-C" option (e.g. "-M8" to tell it to use
+8/10 = 80%).
+
+Note.  When the "-C" option is used with `--find-copies-harder`
+option, 'git diff-{asterisk}' commands feed unmodified filepairs to
+diffcore mechanism as well as modified ones.  This lets the copy
+detector consider unmodified files as copy source candidates at
+the expense of making it slower.  Without `--find-copies-harder`,
+'git diff-{asterisk}' commands can detect copies only if the file that was
+copied happened to have been modified in the same changeset.
+
+
+diffcore-merge-broken: For Putting "Complete Rewrites" Back Together
+--------------------------------------------------------------------
+
+This transformation is used to merge filepairs broken by
+diffcore-break, and not transformed into rename/copy by
+diffcore-rename, back into a single modification.  This always
+runs when diffcore-break is used.
+
+For the purpose of merging broken filepairs back, it uses a
+different "extent of changes" computation from the ones used by
+diffcore-break and diffcore-rename.  It counts only the deletion
+from the original, and does not count insertion.  If you removed
+only 10 lines from a 100-line document, even if you added 910
+new lines to make a new 1000-line document, you did not do a
+complete rewrite.  diffcore-break breaks such a case in order to
+help diffcore-rename to consider such filepairs as candidate of
+rename/copy detection, but if filepairs broken that way were not
+matched with other filepairs to create rename/copy, then this
+transformation merges them back into the original
+"modification".
+
+The "extent of changes" parameter can be tweaked from the
+default 80% (that is, unless more than 80% of the original
+material is deleted, the broken pairs are merged back into a
+single modification) by giving a second number to -B option,
+like these:
+
+* -B50/60 (give 50% "break score" to diffcore-break, use 60%
+  for diffcore-merge-broken).
+
+* -B/60 (the same as above, since diffcore-break defaults to 50%).
+
+Note that earlier implementation left a broken pair as a separate
+creation and deletion patches.  This was an unnecessary hack and
+the latest implementation always merges all the broken pairs
+back into modifications, but the resulting patch output is
+formatted differently for easier review in case of such
+a complete rewrite by showing the entire contents of old version
+prefixed with '-', followed by the entire contents of new
+version prefixed with '+'.
+
+
+diffcore-pickaxe: For Detecting Addition/Deletion of Specified String
+---------------------------------------------------------------------
+
+This transformation limits the set of filepairs to those that change
+specified strings between the preimage and the postimage in a certain
+way.  -S<block of text> and -G<regular expression> options are used to
+specify different ways these strings are sought.
+
+"-S<block of text>" detects filepairs whose preimage and postimage
+have different number of occurrences of the specified block of text.
+By definition, it will not detect in-file moves.  Also, when a
+changeset moves a file wholesale without affecting the interesting
+string, diffcore-rename kicks in as usual, and `-S` omits the filepair
+(since the number of occurrences of that string didn't change in that
+rename-detected filepair).  When used with `--pickaxe-regex`, treat
+the <block of text> as an extended POSIX regular expression to match,
+instead of a literal string.
+
+"-G<regular expression>" (mnemonic: grep) detects filepairs whose
+textual diff has an added or a deleted line that matches the given
+regular expression.  This means that it will detect in-file (or what
+rename-detection considers the same file) moves, which is noise.  The
+implementation runs diff twice and greps, and this can be quite
+expensive.
+
+When `-S` or `-G` are used without `--pickaxe-all`, only filepairs
+that match their respective criterion are kept in the output.  When
+`--pickaxe-all` is used, if even one filepair matches their respective
+criterion in a changeset, the entire changeset is kept.  This behavior
+is designed to make reviewing changes in the context of the whole
+changeset easier.
+
+diffcore-order: For Sorting the Output Based on Filenames
+---------------------------------------------------------
+
+This is used to reorder the filepairs according to the user's
+(or project's) taste, and is controlled by the -O option to the
+'git diff-{asterisk}' commands.
+
+This takes a text file each of whose lines is a shell glob
+pattern.  Filepairs that match a glob pattern on an earlier line
+in the file are output before ones that match a later line, and
+filepairs that do not match any glob pattern are output last.
+
+As an example, a typical orderfile for the core Git probably
+would look like this:
+
+------------------------------------------------
+README
+Makefile
+Documentation
+*.h
+*.c
+t

+NAME
+----
+giteveryday - A useful minimum set of commands for Everyday Git
+
+SYNOPSIS
+--------
+
+Everyday Git With 20 Commands Or So
+
+DESCRIPTION
+-----------
+
+Git users can broadly be grouped into four categories for the purposes of
+describing here a small set of useful command for everyday Git.
+
+*	<<STANDALONE,Individual Developer (Standalone)>> commands are essential
+	for anybody who makes a commit, even for somebody who works alone.
+
+*	If you work with other people, you will need commands listed in
+	the <<PARTICIPANT,Individual Developer (Participant)>> section as well.
+
+*	People who play the <<INTEGRATOR,Integrator>> role need to learn some
+	more commands in addition to the above.
+
+*	<<ADMINISTRATION,Repository Administration>> commands are for system
+	administrators who are responsible for the care and feeding
+	of Git repositories.
+
+
+Individual Developer (Standalone)[[STANDALONE]]
+-----------------------------------------------
+
+A standalone individual developer does not exchange patches with
+other people, and works alone in a single repository, using the
+following commands.
+
+  * linkgit:git-init[1] to create a new repository.
+
+  * linkgit:git-log[1] to see what happened.
+
+  * linkgit:git-checkout[1] and linkgit:git-branch[1] to switch
+    branches.
+
+  * linkgit:git-add[1] to manage the index file.
+
+  * linkgit:git-diff[1] and linkgit:git-status[1] to see what
+    you are in the middle of doing.
+
+  * linkgit:git-commit[1] to advance the current branch.
+
+  * linkgit:git-reset[1] and linkgit:git-checkout[1] (with
+    pathname parameters) to undo changes.
+
+  * linkgit:git-merge[1] to merge between local branches.
+
+  * linkgit:git-rebase[1] to maintain topic branches.
+
+  * linkgit:git-tag[1] to mark a known point.
+
+Examples
+~~~~~~~~
+
+Use a tarball as a starting point for a new repository.::
++
+------------
+$ tar zxf frotz.tar.gz
+$ cd frotz
+$ git init
+$ git add . <1>
+$ git commit -m "import of frotz source tree."
+$ git tag v2.43 <2>
+------------
++
+<1> add everything under the current directory.
+<2> make a lightweight, unannotated tag.
+
+Create a topic branch and develop.::
++
+------------
+$ git checkout -b alsa-audio <1>
+$ edit/compile/test
+$ git checkout -- curses/ux_audio_oss.c <2>
+$ git add curses/ux_audio_alsa.c <3>
+$ edit/compile/test
+$ git diff HEAD <4>
+$ git commit -a -s <5>
+$ edit/compile/test
+$ git diff HEAD^ <6>
+$ git commit -a --amend <7>
+$ git checkout master <8>
+$ git merge alsa-audio <9>
+$ git log --since='3 days ago' <10>
+$ git log v2.43.. curses/ <11>
+------------
++
+<1> create a new topic branch.
+<2> revert your botched changes in `curses/ux_audio_oss.c`.
+<3> you need to tell Git if you added a new file; removal and
+modification will be caught if you do `git commit -a` later.
+<4> to see what changes you are committing.
+<5> commit everything, as you have tested, with your sign-off.
+<6> look at all your changes including the previous commit.
+<7> amend the previous commit, adding all your new changes,
+using your original message.
+<8> switch to the master branch.
+<9> merge a topic branch into your master branch.
+<10> review commit logs; other forms to limit output can be
+combined and include `-10` (to show up to 10 commits),
+`--until=2005-12-10`, etc.
+<11> view only the changes that touch what's in `curses/`
+directory, since `v2.43` tag.
+
+
+Individual Developer (Participant)[[PARTICIPANT]]
+-------------------------------------------------
+
+A developer working as a participant in a group project needs to
+learn how to communicate with others, and uses these commands in
+addition to the ones needed by a standalone developer.
+
+  * linkgit:git-clone[1] from the upstream to prime your local
+    repository.
+
+  * linkgit:git-pull[1] and linkgit:git-fetch[1] from "origin"
+    to keep up-to-date with the upstream.
+
+  * linkgit:git-push[1] to shared repository, if you adopt CVS
+    style shared repository workflow.
+
+  * linkgit:git-format-patch[1] to prepare e-mail submission, if
+    you adopt Linux kernel-style public forum workflow.
+
+  * linkgit:git-send-email[1] to send your e-mail submission without
+    corruption by your MUA.
+
+  * linkgit:git-request-pull[1] to create a summary of changes
+    for your upstream to pull.
+
+
+Examples
+~~~~~~~~
+
+Clone the upstream and work on it.  Feed changes to upstream.::
++
+------------
+$ git clone git://git.kernel.org/pub/scm/.../torvalds/linux-2.6 my2.6
+$ cd my2.6
+$ git checkout -b mine master <1>
+$ edit/compile/test; git commit -a -s <2>
+$ git format-patch master <3>
+$ git send-email --to="person <email@example.com>" 00*.patch <4>
+$ git checkout master <5>
+$ git pull <6>
+$ git log -p ORIG_HEAD.. arch/i386 include/asm-i386 <7>
+$ git ls-remote --heads http://git.kernel.org/.../jgarzik/libata-dev.git <8>
+$ git pull git://git.kernel.org/pub/.../jgarzik/libata-dev.git ALL <9>
+$ git reset --hard ORIG_HEAD <10>
+$ git gc <11>
+------------
++
+<1> checkout a new branch `mine` from master.
+<2> repeat as needed.
+<3> extract patches from your branch, relative to master,
+<4> and email them.
+<5> return to `master`, ready to see what's new
+<6> `git pull` fetches from `origin` by default and merges into the
+current branch.
+<7> immediately after pulling, look at the changes done upstream
+since last time we checked, only in the
+area we are interested in.
+<8> check the branch names in an external repository (if not known).
+<9> fetch from a specific branch `ALL` from a specific repository
+and merge it.
+<10> revert the pull.
+<11> garbage collect leftover objects from reverted pull.
+
+
+Push into another repository.::
++
+------------
+satellite$ git clone mothership:frotz frotz <1>
+satellite$ cd frotz
+satellite$ git config --get-regexp '^(remote|branch)\.' <2>
+remote.origin.url mothership:frotz
+remote.origin.fetch refs/heads/*:refs/remotes/origin/*
+branch.master.remote origin
+branch.master.merge refs/heads/master
+satellite$ git config remote.origin.push \
+	   +refs/heads/*:refs/remotes/satellite/* <3>
+satellite$ edit/compile/test/commit
+satellite$ git push origin <4>
+
+mothership$ cd frotz
+mothership$ git checkout master
+mothership$ git merge satellite/master <5>
+------------
++
+<1> mothership machine has a frotz repository under your home
+directory; clone from it to start a repository on the satellite
+machine.
+<2> clone sets these configuration variables by default.
+It arranges `git pull` to fetch and store the branches of mothership
+machine to local `remotes/origin/*` remote-tracking branches.
+<3> arrange `git push` to push all local branches to
+their corresponding branch of the mothership machine.
+<4> push will stash all our work away on `remotes/satellite/*`
+remote-tracking branches on the mothership machine.  You could use this
+as a back-up method. Likewise, you can pretend that mothership
+"fetched" from you (useful when access is one sided).
+<5> on mothership machine, merge the work done on the satellite
+machine into the master branch.
+
+Branch off of a specific tag.::
++
+------------
+$ git checkout -b private2.6.14 v2.6.14 <1>
+$ edit/compile/test; git commit -a
+$ git checkout master
+$ git cherry-pick v2.6.14..private2.6.14 <2>
+------------
++
+<1> create a private branch based on a well known (but somewhat behind)
+tag.
+<2> forward port all changes in `private2.6.14` branch to `master` branch
+without a formal "merging". Or longhand +
+`git format-patch -k -m --stdout v2.6.14..private2.6.14 |
+  git am -3 -k`
+
+An alternate participant submission mechanism is using the
+`git request-pull` or pull-request mechanisms (e.g as used on
+GitHub (www.github.com) to notify your upstream of your
+contribution.
+
+Integrator[[INTEGRATOR]]
+------------------------
+
+A fairly central person acting as the integrator in a group
+project receives changes made by others, reviews and integrates
+them and publishes the result for others to use, using these
+commands in addition to the ones needed by participants.
+
+This section can also be used by those who respond to `git
+request-pull` or pull-request on GitHub (www.github.com) to
+integrate the work of others into their history. An sub-area
+lieutenant for a repository will act both as a participant and
+as an integrator.
+
+
+  * linkgit:git-am[1] to apply patches e-mailed in from your
+    contributors.
+
+  * linkgit:git-pull[1] to merge from your trusted lieutenants.
+
+  * linkgit:git-format-patch[1] to prepare and send suggested
+    alternative to contributors.
+
+  * linkgit:git-revert[1] to undo botched commits.
+
+  * linkgit:git-push[1] to publish the bleeding edge.
+
+
+Examples
+~~~~~~~~
+
+A typical integrator's Git day.::
++
+------------
+$ git status <1>
+$ git branch --no-merged master <2>
+$ mailx <3>
+& s 2 3 4 5 ./+to-apply
+& s 7 8 ./+hold-linus
+& q
+$ git checkout -b topic/one master
+$ git am -3 -i -s ./+to-apply <4>
+$ compile/test
+$ git checkout -b hold/linus && git am -3 -i -s ./+hold-linus <5>
+$ git checkout topic/one && git rebase master <6>
+$ git checkout pu && git reset --hard next <7>
+$ git merge topic/one topic/two && git merge hold/linus <8>
+$ git checkout maint
+$ git cherry-pick master~4 <9>
+$ compile/test
+$ git tag -s -m "GIT 0.99.9x" v0.99.9x <10>
+$ git fetch ko && for branch in master maint next pu <11>
+    do
+	git show-branch ko/$branch $branch <12>
+    done
+$ git push --follow-tags ko <13>
+------------
++
+<1> see what you were in the middle of doing, if anything.
+<2> see which branches haven't been merged into `master` yet.
+Likewise for any other integration branches e.g. `maint`, `next`
+and `pu` (potential updates).
+<3> read mails, save ones that are applicable, and save others
+that are not quite ready (other mail readers are available).
+<4> apply them, interactively, with your sign-offs.
+<5> create topic branch as needed and apply, again with sign-offs.
+<6> rebase internal topic branch that has not been merged to the
+master or exposed as a part of a stable branch.
+<7> restart `pu` every time from the next.
+<8> and bundle topic branches still cooking.
+<9> backport a critical fix.
+<10> create a signed tag.
+<11> make sure master was not accidentally rewound beyond that
+already pushed out.  `ko` shorthand points at the Git maintainer's
+repository at kernel.org, and looks like this:
++
+------------
+(in .git/config)
+[remote "ko"]
+	url = kernel.org:/pub/scm/git/git.git
+	fetch = refs/heads/*:refs/remotes/ko/*
+	push = refs/heads/master
+	push = refs/heads/next
+	push = +refs/heads/pu
+	push = refs/heads/maint
+------------
++
+<12> In the output from `git show-branch`, `master` should have
+everything `ko/master` has, and `next` should have
+everything `ko/next` has, etc.
+<13> push out the bleeding edge, together with new tags that point
+into the pushed history.
+
+
+Repository Administration[[ADMINISTRATION]]
+-------------------------------------------
+
+A repository administrator uses the following tools to set up
+and maintain access to the repository by developers.
+
+  * linkgit:git-daemon[1] to allow anonymous download from
+    repository.
+
+  * linkgit:git-shell[1] can be used as a 'restricted login shell'
+    for shared central repository users.
+
+  * linkgit:git-http-backend[1] provides a server side implementation
+    of Git-over-HTTP ("Smart http") allowing both fetch and push services.
+
+  * linkgit:gitweb[1] provides a web front-end to Git repositories,
+    which can be set-up using the linkgit:git-instaweb[1] script.
+
+link:howto/update-hook-example.html[update hook howto] has a good
+example of managing a shared central repository.
+
+In addition there are a number of other widely deployed hosting, browsing
+and reviewing solutions such as:
+
+  * gitolite, gerrit code review, cgit and others.
+
+Examples
+~~~~~~~~
+We assume the following in /etc/services::
++
+------------
+$ grep 9418 /etc/services
+git		9418/tcp		# Git Version Control System
+------------
+
+Run git-daemon to serve /pub/scm from inetd.::
++
+------------
+$ grep git /etc/inetd.conf
+git	stream	tcp	nowait	nobody \
+  /usr/bin/git-daemon git-daemon --inetd --export-all /pub/scm
+------------
++
+The actual configuration line should be on one line.
+
+Run git-daemon to serve /pub/scm from xinetd.::
++
+------------
+$ cat /etc/xinetd.d/git-daemon
+# default: off
+# description: The Git server offers access to Git repositories
+service git
+{
+	disable = no
+	type            = UNLISTED
+	port            = 9418
+	socket_type     = stream
+	wait            = no
+	user            = nobody
+	server          = /usr/bin/git-daemon
+	server_args     = --inetd --export-all --base-path=/pub/scm
+	log_on_failure  += USERID
+}
+------------
++
+Check your xinetd(8) documentation and setup, this is from a Fedora system.
+Others might be different.
+
+Give push/pull only access to developers using git-over-ssh.::
+
+e.g. those using:
+`$ git push/pull ssh://host.xz/pub/scm/project`
++
+------------
+$ grep git /etc/passwd <1>
+alice:x:1000:1000::/home/alice:/usr/bin/git-shell
+bob:x:1001:1001::/home/bob:/usr/bin/git-shell
+cindy:x:1002:1002::/home/cindy:/usr/bin/git-shell
+david:x:1003:1003::/home/david:/usr/bin/git-shell
+$ grep git /etc/shells <2>
+/usr/bin/git-shell
+------------
++
+<1> log-in shell is set to /usr/bin/git-shell, which does not
+allow anything but `git push` and `git pull`.  The users require
+ssh access to the machine.
+<2> in many distributions /etc/shells needs to list what is used
+as the login shell.
+
+CVS-style shared repository.::
++
+------------
+$ grep git /etc/group <1>
+git:x:9418:alice,bob,cindy,david
+$ cd /home/devo.git
+$ ls -l <2>
+  lrwxrwxrwx   1 david git    17 Dec  4 22:40 HEAD -> refs/heads/master

+NAME
+----
+githooks - Hooks used by Git
+
+SYNOPSIS
+--------
+$GIT_DIR/hooks/*
+
+
+DESCRIPTION
+-----------
+
+Hooks are little scripts you can place in `$GIT_DIR/hooks`
+directory to trigger action at certain points.  When
+'git init' is run, a handful of example hooks are copied into the
+`hooks` directory of the new repository, but by default they are
+all disabled.  To enable a hook, rename it by removing its `.sample`
+suffix.
+
+NOTE: It is also a requirement for a given hook to be executable.
+However - in a freshly initialized repository - the `.sample` files are
+executable by default.
+
+This document describes the currently defined hooks.
+
+HOOKS
+-----
+
+applypatch-msg
+~~~~~~~~~~~~~~
+
+This hook is invoked by 'git am' script.  It takes a single
+parameter, the name of the file that holds the proposed commit
+log message.  Exiting with non-zero status causes
+'git am' to abort before applying the patch.
+
+The hook is allowed to edit the message file in place, and can
+be used to normalize the message into some project standard
+format (if the project has one). It can also be used to refuse
+the commit after inspecting the message file.
+
+The default 'applypatch-msg' hook, when enabled, runs the
+'commit-msg' hook, if the latter is enabled.
+
+pre-applypatch
+~~~~~~~~~~~~~~
+
+This hook is invoked by 'git am'.  It takes no parameter, and is
+invoked after the patch is applied, but before a commit is made.
+
+If it exits with non-zero status, then the working tree will not be
+committed after applying the patch.
+
+It can be used to inspect the current working tree and refuse to
+make a commit if it does not pass certain test.
+
+The default 'pre-applypatch' hook, when enabled, runs the
+'pre-commit' hook, if the latter is enabled.
+
+post-applypatch
+~~~~~~~~~~~~~~~
+
+This hook is invoked by 'git am'.  It takes no parameter,
+and is invoked after the patch is applied and a commit is made.
+
+This hook is meant primarily for notification, and cannot affect
+the outcome of 'git am'.
+
+pre-commit
+~~~~~~~~~~
+
+This hook is invoked by 'git commit', and can be bypassed
+with `--no-verify` option.  It takes no parameter, and is
+invoked before obtaining the proposed commit log message and
+making a commit.  Exiting with non-zero status from this script
+causes the 'git commit' to abort.
+
+The default 'pre-commit' hook, when enabled, catches introduction
+of lines with trailing whitespaces and aborts the commit when
+such a line is found.
+
+All the 'git commit' hooks are invoked with the environment
+variable `GIT_EDITOR=:` if the command will not bring up an editor
+to modify the commit message.
+
+prepare-commit-msg
+~~~~~~~~~~~~~~~~~~
+
+This hook is invoked by 'git commit' right after preparing the
+default log message, and before the editor is started.
+
+It takes one to three parameters.  The first is the name of the file
+that contains the commit log message.  The second is the source of the commit
+message, and can be: `message` (if a `-m` or `-F` option was
+given); `template` (if a `-t` option was given or the
+configuration option `commit.template` is set); `merge` (if the
+commit is a merge or a `.git/MERGE_MSG` file exists); `squash`
+(if a `.git/SQUASH_MSG` file exists); or `commit`, followed by
+a commit SHA-1 (if a `-c`, `-C` or `--amend` option was given).
+
+If the exit status is non-zero, 'git commit' will abort.
+
+The purpose of the hook is to edit the message file in place, and
+it is not suppressed by the `--no-verify` option.  A non-zero exit
+means a failure of the hook and aborts the commit.  It should not
+be used as replacement for pre-commit hook.
+
+The sample `prepare-commit-msg` hook that comes with Git comments
+out the `Conflicts:` part of a merge's commit message.
+
+commit-msg
+~~~~~~~~~~
+
+This hook is invoked by 'git commit', and can be bypassed
+with `--no-verify` option.  It takes a single parameter, the
+name of the file that holds the proposed commit log message.
+Exiting with non-zero status causes the 'git commit' to
+abort.
+
+The hook is allowed to edit the message file in place, and can
+be used to normalize the message into some project standard
+format (if the project has one). It can also be used to refuse
+the commit after inspecting the message file.
+
+The default 'commit-msg' hook, when enabled, detects duplicate
+"Signed-off-by" lines, and aborts the commit if one is found.
+
+post-commit
+~~~~~~~~~~~
+
+This hook is invoked by 'git commit'.  It takes no
+parameter, and is invoked after a commit is made.
+
+This hook is meant primarily for notification, and cannot affect
+the outcome of 'git commit'.
+
+pre-rebase
+~~~~~~~~~~
+
+This hook is called by 'git rebase' and can be used to prevent a
+branch from getting rebased.  The hook may be called with one or
+two parameters.  The first parameter is the upstream from which
+the series was forked.  The second parameter is the branch being
+rebased, and is not set when rebasing the current branch.
+
+post-checkout
+~~~~~~~~~~~~~
+
+This hook is invoked when a 'git checkout' is run after having updated the
+worktree.  The hook is given three parameters: the ref of the previous HEAD,
+the ref of the new HEAD (which may or may not have changed), and a flag
+indicating whether the checkout was a branch checkout (changing branches,
+flag=1) or a file checkout (retrieving a file from the index, flag=0).
+This hook cannot affect the outcome of 'git checkout'.
+
+It is also run after 'git clone', unless the --no-checkout (-n) option is
+used. The first parameter given to the hook is the null-ref, the second the
+ref of the new HEAD and the flag is always 1.
+
+This hook can be used to perform repository validity checks, auto-display
+differences from the previous HEAD if different, or set working dir metadata
+properties.
+
+post-merge
+~~~~~~~~~~
+
+This hook is invoked by 'git merge', which happens when a 'git pull'
+is done on a local repository.  The hook takes a single parameter, a status
+flag specifying whether or not the merge being done was a squash merge.
+This hook cannot affect the outcome of 'git merge' and is not executed,
+if the merge failed due to conflicts.
+
+This hook can be used in conjunction with a corresponding pre-commit hook to
+save and restore any form of metadata associated with the working tree
+(e.g.: permissions/ownership, ACLS, etc).  See contrib/hooks/setgitperms.perl
+for an example of how to do this.
+
+pre-push
+~~~~~~~~
+
+This hook is called by 'git push' and can be used to prevent a push from taking
+place.  The hook is called with two parameters which provide the name and
+location of the destination remote, if a named remote is not being used both
+values will be the same.
+
+Information about what is to be pushed is provided on the hook's standard
+input with lines of the form:
+
+  <local ref> SP <local sha1> SP <remote ref> SP <remote sha1> LF
+
+For instance, if the command +git push origin master:foreign+ were run the
+hook would receive a line like the following:
+
+  refs/heads/master 67890 refs/heads/foreign 12345
+
+although the full, 40-character SHA-1s would be supplied.  If the foreign ref
+does not yet exist the `<remote SHA-1>` will be 40 `0`.  If a ref is to be
+deleted, the `<local ref>` will be supplied as `(delete)` and the `<local
+SHA-1>` will be 40 `0`.  If the local commit was specified by something other
+than a name which could be expanded (such as `HEAD~`, or a SHA-1) it will be
+supplied as it was originally given.
+
+If this hook exits with a non-zero status, 'git push' will abort without
+pushing anything.  Information about why the push is rejected may be sent
+to the user by writing to standard error.
+
+[[pre-receive]]
+pre-receive
+~~~~~~~~~~~
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git push' is done on a local repository.
+Just before starting to update refs on the remote repository, the
+pre-receive hook is invoked.  Its exit status determines the success
+or failure of the update.
+
+This hook executes once for the receive operation. It takes no
+arguments, but for each ref to be updated it receives on standard
+input a line of the format:
+
+  <old-value> SP <new-value> SP <ref-name> LF
+
+where `<old-value>` is the old object name stored in the ref,
+`<new-value>` is the new object name to be stored in the ref and
+`<ref-name>` is the full name of the ref.
+When creating a new ref, `<old-value>` is 40 `0`.
+
+If the hook exits with non-zero status, none of the refs will be
+updated. If the hook exits with zero, updating of individual refs can
+still be prevented by the <<update,'update'>> hook.
+
+Both standard output and standard error output are forwarded to
+'git send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+[[update]]
+update
+~~~~~~
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git push' is done on a local repository.
+Just before updating the ref on the remote repository, the update hook
+is invoked.  Its exit status determines the success or failure of
+the ref update.
+
+The hook executes once for each ref to be updated, and takes
+three parameters:
+
+ - the name of the ref being updated,
+ - the old object name stored in the ref,
+ - and the new object name to be stored in the ref.
+
+A zero exit from the update hook allows the ref to be updated.
+Exiting with a non-zero status prevents 'git-receive-pack'
+from updating that ref.
+
+This hook can be used to prevent 'forced' update on certain refs by
+making sure that the object name is a commit object that is a
+descendant of the commit object named by the old object name.
+That is, to enforce a "fast-forward only" policy.
+
+It could also be used to log the old..new status.  However, it
+does not know the entire set of branches, so it would end up
+firing one e-mail per ref when used naively, though.  The
+<<post-receive,'post-receive'>> hook is more suited to that.
+
+Another use suggested on the mailing list is to use this hook to
+implement access control which is finer grained than the one
+based on filesystem group.
+
+Both standard output and standard error output are forwarded to
+'git send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+The default 'update' hook, when enabled--and with
+`hooks.allowunannotated` config option unset or set to false--prevents
+unannotated tags to be pushed.
+
+[[post-receive]]
+post-receive
+~~~~~~~~~~~~
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git push' is done on a local repository.
+It executes on the remote repository once after all the refs have
+been updated.
+
+This hook executes once for the receive operation.  It takes no
+arguments, but gets the same information as the
+<<pre-receive,'pre-receive'>>
+hook does on its standard input.
+
+This hook does not affect the outcome of 'git-receive-pack', as it
+is called after the real work is done.
+
+This supersedes the <<post-update,'post-update'>> hook in that it gets
+both old and new values of all the refs in addition to their
+names.
+
+Both standard output and standard error output are forwarded to
+'git send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+The default 'post-receive' hook is empty, but there is
+a sample script `post-receive-email` provided in the `contrib/hooks`
+directory in Git distribution, which implements sending commit
+emails.
+
+[[post-update]]
+post-update
+~~~~~~~~~~~
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git push' is done on a local repository.
+It executes on the remote repository once after all the refs have
+been updated.
+
+It takes a variable number of parameters, each of which is the
+name of ref that was actually updated.
+
+This hook is meant primarily for notification, and cannot affect
+the outcome of 'git-receive-pack'.
+
+The 'post-update' hook can tell what are the heads that were pushed,
+but it does not know what their original and updated values are,
+so it is a poor place to do log old..new. The
+<<post-receive,'post-receive'>> hook does get both original and
+updated values of the refs. You might consider it instead if you need
+them.
+
+When enabled, the default 'post-update' hook runs
+'git update-server-info' to keep the information used by dumb
+transports (e.g., HTTP) up-to-date.  If you are publishing
+a Git repository that is accessible via HTTP, you should
+probably enable this hook.
+
+Both standard output and standard error output are forwarded to
+'git send-pack' on the other end, so you can simply `echo` messages
+for the user.
+
+push-to-checkout
+~~~~~~~~~~~~~~~~
+
+This hook is invoked by 'git-receive-pack' on the remote repository,
+which happens when a 'git push' is done on a local repository, when
+the push tries to update the branch that is currently checked out
+and the `receive.denyCurrentBranch` configuration variable is set to
+`updateInstead`.  Such a push by default is refused if the working
+tree and the index of the remote repository has any difference from
+the currently checked out commit; when both the working tree and the
+index match the current commit, they are updated to match the newly
+pushed tip of the branch.  This hook is to be used to override the
+default behaviour.
+
+The hook receives the commit with which the tip of the current
+branch is going to be updated.  It can exit with a non-zero status
+to refuse the push (when it does so, it must not modify the index or
+the working tree).  Or it can make any necessary changes to the
+working tree and to the index to bring them to the desired state
+when the tip of the current branch is updated to the new commit, and
+exit with a zero status.
+
+For example, the hook can simply run `git read-tree -u -m HEAD "$1"`
+in order to emulate 'git fetch' that is run in the reverse direction
+with `git push`, as the two-tree form of `read-tree -u -m` is
+essentially the same as `git checkout` that switches branches while
+keeping the local changes in the working tree that do not interfere
+with the difference between the branches.
+
+
+pre-auto-gc
+~~~~~~~~~~~
+
+This hook is invoked by 'git gc --auto'. It takes no parameter, and
+exiting with non-zero status from this script causes the 'git gc --auto'
+to abort.
+
+post-rewrite
+~~~~~~~~~~~~
+
+This hook is invoked by commands that rewrite commits (`git commit
+--amend`, 'git-rebase'; currently 'git-filter-branch' does 'not' call
+it!).  Its first argument denotes the command it was invoked by:
+currently one of `amend` or `rebase`.  Further command-dependent
+arguments may be passed in the future.
+
+The hook receives a list of the rewritten commits on stdin, in the
+format
+
+  <old-sha1> SP <new-sha1> [ SP <extra-info> ] LF
+
+The 'extra-info' is again command-dependent.  If it is empty, the
+preceding SP is also omitted.  Currently, no commands pass any
+'extra-info'.
+
+The hook always runs after the automatic note copying (see
+"notes.rewrite.<command>" in linkgit:git-config.txt[1]) has happened, and
+thus has access to these notes.
+
+The following command-specific comments apply:
+
+rebase::
+	For the 'squash' and 'fixup' operation, all commits that were
+	squashed are listed as being rewritten to the squashed commit.
+	This means that there will be several lines sharing the same
+	'new-sha1'.
++
+The commits are guaranteed to be listed in the order that they were
+processed by rebase.

+
+NAME
+----
+gitignore - Specifies intentionally untracked files to ignore
+
+SYNOPSIS
+--------
+$HOME/.config/git/ignore, $GIT_DIR/info/exclude, .gitignore
+
+DESCRIPTION
+-----------
+
+A `gitignore` file specifies intentionally untracked files that
+Git should ignore.
+Files already tracked by Git are not affected; see the NOTES
+below for details.
+
+Each line in a `gitignore` file specifies a pattern.
+When deciding whether to ignore a path, Git normally checks
+`gitignore` patterns from multiple sources, with the following
+order of precedence, from highest to lowest (within one level of
+precedence, the last matching pattern decides the outcome):
+
+ * Patterns read from the command line for those commands that support
+   them.
+
+ * Patterns read from a `.gitignore` file in the same directory
+   as the path, or in any parent directory, with patterns in the
+   higher level files (up to the toplevel of the work tree) being overridden
+   by those in lower level files down to the directory containing the file.
+   These patterns match relative to the location of the
+   `.gitignore` file.  A project normally includes such
+   `.gitignore` files in its repository, containing patterns for
+   files generated as part of the project build.
+
+ * Patterns read from `$GIT_DIR/info/exclude`.
+
+ * Patterns read from the file specified by the configuration
+   variable 'core.excludesFile'.
+
+Which file to place a pattern in depends on how the pattern is meant to
+be used.
+
+ * Patterns which should be version-controlled and distributed to
+   other repositories via clone (i.e., files that all developers will want
+   to ignore) should go into a `.gitignore` file.
+
+ * Patterns which are
+   specific to a particular repository but which do not need to be shared
+   with other related repositories (e.g., auxiliary files that live inside
+   the repository but are specific to one user's workflow) should go into
+   the `$GIT_DIR/info/exclude` file.
+
+ * Patterns which a user wants Git to
+   ignore in all situations (e.g., backup or temporary files generated by
+   the user's editor of choice) generally go into a file specified by
+   `core.excludesFile` in the user's `~/.gitconfig`. Its default value is
+   $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or
+   empty, $HOME/.config/git/ignore is used instead.
+
+The underlying Git plumbing tools, such as
+'git ls-files' and 'git read-tree', read
+`gitignore` patterns specified by command-line options, or from
+files specified by command-line options.  Higher-level Git
+tools, such as 'git status' and 'git add',
+use patterns from the sources specified above.
+
+PATTERN FORMAT
+--------------
+
+ - A blank line matches no files, so it can serve as a separator
+   for readability.
+
+ - A line starting with # serves as a comment.
+   Put a backslash ("`\`") in front of the first hash for patterns
+   that begin with a hash.
+
+ - Trailing spaces are ignored unless they are quoted with backslash
+   ("`\`").
+
+ - An optional prefix "`!`" which negates the pattern; any
+   matching file excluded by a previous pattern will become
+   included again. It is not possible to re-include a file if a parent
+   directory of that file is excluded. Git doesn't list excluded
+   directories for performance reasons, so any patterns on contained
+   files have no effect, no matter where they are defined.
+   Put a backslash ("`\`") in front of the first "`!`" for patterns
+   that begin with a literal "`!`", for example, "`\!important!.txt`".
+
+ - If the pattern ends with a slash, it is removed for the
+   purpose of the following description, but it would only find
+   a match with a directory.  In other words, `foo/` will match a
+   directory `foo` and paths underneath it, but will not match a
+   regular file or a symbolic link `foo` (this is consistent
+   with the way how pathspec works in general in Git).
+
+ - If the pattern does not contain a slash '/', Git treats it as
+   a shell glob pattern and checks for a match against the
+   pathname relative to the location of the `.gitignore` file
+   (relative to the toplevel of the work tree if not from a
+   `.gitignore` file).
+
+ - Otherwise, Git treats the pattern as a shell glob suitable
+   for consumption by fnmatch(3) with the FNM_PATHNAME flag:
+   wildcards in the pattern will not match a / in the pathname.
+   For example, "Documentation/{asterisk}.html" matches
+   "Documentation/git.html" but not "Documentation/ppc/ppc.html"
+   or "tools/perf/Documentation/perf.html".
+
+ - A leading slash matches the beginning of the pathname.
+   For example, "/{asterisk}.c" matches "cat-file.c" but not
+   "mozilla-sha1/sha1.c".
+
+Two consecutive asterisks ("`**`") in patterns matched against
+full pathname may have special meaning:
+
+ - A leading "`**`" followed by a slash means match in all
+   directories. For example, "`**/foo`" matches file or directory
+   "`foo`" anywhere, the same as pattern "`foo`". "`**/foo/bar`"
+   matches file or directory "`bar`" anywhere that is directly
+   under directory "`foo`".
+
+ - A trailing "`/**`" matches everything inside. For example,
+   "`abc/**`" matches all files inside directory "`abc`", relative
+   to the location of the `.gitignore` file, with infinite depth.
+
+ - A slash followed by two consecutive asterisks then a slash
+   matches zero or more directories. For example, "`a/**/b`"
+   matches "`a/b`", "`a/x/b`", "`a/x/y/b`" and so on.
+
+ - Other consecutive asterisks are considered invalid.
+
+NOTES
+-----
+
+The purpose of gitignore files is to ensure that certain files
+not tracked by Git remain untracked.
+
+To stop tracking a file that is currently tracked, use
+'git rm --cached'.
+
+EXAMPLES
+--------
+
+--------------------------------------------------------------
+    $ git status
+    [...]
+    # Untracked files:
+    [...]
+    #       Documentation/foo.html
+    #       Documentation/gitignore.html
+    #       file.o
+    #       lib.a
+    #       src/internal.o
+    [...]
+    $ cat .git/info/exclude
+    # ignore objects and archives, anywhere in the tree.
+    *.[oa]
+    $ cat Documentation/.gitignore
+    # ignore generated html files,
+    *.html
+    # except foo.html which is maintained by hand
+    !foo.html
+    $ git status
+    [...]
+    # Untracked files:
+    [...]
+    #       Documentation/foo.html
+    [...]
+--------------------------------------------------------------
+
+Another example:
+
+--------------------------------------------------------------
+    $ cat .gitignore
+    vmlinux*
+    $ ls arch/foo/kernel/vm*
+    arch/foo/kernel/vmlinux.lds.S
+    $ echo '!/vmlinux*' >arch/foo/kernel/.gitignore
+--------------------------------------------------------------
+
+The second .gitignore prevents Git from ignoring
+`arch/foo/kernel/vmlinux.lds.S`.
+
+Example to exclude everything except a specific directory `foo/bar`
+(note the `/*` - without the slash, the wildcard would also exclude
+everything within `foo/bar`):
+
+--------------------------------------------------------------
+    $ cat .gitignore
+    # exclude everything except directory foo/bar
+    /*
+    !/foo
+    /foo/*
+    !/foo/bar

+=============
+
+NAME
+----
+gitmodules - defining submodule properties
+
+SYNOPSIS
+--------
+$GIT_WORK_DIR/.gitmodules
+
+
+DESCRIPTION
+-----------
+
+The `.gitmodules` file, located in the top-level directory of a Git
+working tree, is a text file with a syntax matching the requirements
+of linkgit:git-config[1].
+
+The file contains one subsection per submodule, and the subsection value
+is the name of the submodule. The name is set to the path where the
+submodule has been added unless it was customized with the '--name'
+option of 'git submodule add'. Each submodule section also contains the
+following required keys:
+
+submodule.<name>.path::
+	Defines the path, relative to the top-level directory of the Git
+	working tree, where the submodule is expected to be checked out.
+	The path name must not end with a `/`. All submodule paths must
+	be unique within the .gitmodules file.
+
+submodule.<name>.url::
+	Defines a URL from which the submodule repository can be cloned.
+	This may be either an absolute URL ready to be passed to
+	linkgit:git-clone[1] or (if it begins with ./ or ../) a location
+	relative to the superproject's origin repository.
+
+In addition, there are a number of optional keys:
+
+submodule.<name>.update::
+	Defines the default update procedure for the named submodule,
+	i.e. how the submodule is updated by "git submodule update"
+	command in the superproject. This is only used by `git
+	submodule init` to initialize the configuration variable of
+	the same name. Allowed values here are 'checkout', 'rebase',
+	'merge' or 'none'. See description of 'update' command in
+	linkgit:git-submodule[1] for their meaning. Note that the
+	'!command' form is intentionally ignored here for security
+	reasons.
+
+submodule.<name>.branch::
+	A remote branch name for tracking updates in the upstream submodule.
+	If the option is not specified, it defaults to 'master'.  See the
+	`--remote` documentation in linkgit:git-submodule[1] for details.
+
+submodule.<name>.fetchRecurseSubmodules::
+	This option can be used to control recursive fetching of this
+	submodule. If this option is also present in the submodules entry in
+	.git/config of the superproject, the setting there will override the
+	one found in .gitmodules.
+	Both settings can be overridden on the command line by using the
+	"--[no-]recurse-submodules" option to "git fetch" and "git pull".
+
+submodule.<name>.ignore::
+	Defines under what circumstances "git status" and the diff family show
+	a submodule as modified. When set to "all", it will never be considered
+	modified (but will nonetheless show up in the output of status and
+	commit when it has been staged), "dirty" will ignore all changes
+	to the submodules work tree and
+	takes only differences between the HEAD of the submodule and the commit
+	recorded in the superproject into account. "untracked" will additionally
+	let submodules with modified tracked files in their work tree show up.
+	Using "none" (the default when this option is not set) also shows
+	submodules that have untracked files in their work tree as changed.
+	If this option is also present in the submodules entry in .git/config of
+	the superproject, the setting there will override the one found in
+	.gitmodules.
+	Both settings can be overridden on the command line by using the
+	"--ignore-submodule" option. The 'git submodule' commands are not
+	affected by this setting.
+
+
+EXAMPLES
+--------
+
+Consider the following .gitmodules file:
+
+	[submodule "libfoo"]
+		path = include/foo
+		url = git://foo.com/git/lib.git
+
+	[submodule "libbar"]
+		path = include/bar
+		url = git://bar.com/git/lib.git
+
+
+This defines two submodules, `libfoo` and `libbar`. These are expected to
+be checked out in the paths 'include/foo' and 'include/bar', and for both
+submodules a URL is specified which can be used for cloning the submodules.

+================
+
+NAME
+----
+gitnamespaces - Git namespaces
+
+SYNOPSIS
+--------
+[verse]
+GIT_NAMESPACE=<namespace> 'git upload-pack'
+GIT_NAMESPACE=<namespace> 'git receive-pack'
+
+
+DESCRIPTION
+-----------
+
+Git supports dividing the refs of a single repository into multiple
+namespaces, each of which has its own branches, tags, and HEAD.  Git can
+expose each namespace as an independent repository to pull from and push
+to, while sharing the object store, and exposing all the refs to
+operations such as linkgit:git-gc[1].
+
+Storing multiple repositories as namespaces of a single repository
+avoids storing duplicate copies of the same objects, such as when
+storing multiple branches of the same source.  The alternates mechanism
+provides similar support for avoiding duplicates, but alternates do not
+prevent duplication between new objects added to the repositories
+without ongoing maintenance, while namespaces do.
+
+To specify a namespace, set the `GIT_NAMESPACE` environment variable to
+the namespace.  For each ref namespace, Git stores the corresponding
+refs in a directory under `refs/namespaces/`.  For example,
+`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`.  You
+can also specify namespaces via the `--namespace` option to
+linkgit:git[1].
+
+Note that namespaces which include a `/` will expand to a hierarchy of
+namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under
+`refs/namespaces/foo/refs/namespaces/bar/`.  This makes paths in
+`GIT_NAMESPACE` behave hierarchically, so that cloning with
+`GIT_NAMESPACE=foo/bar` produces the same result as cloning with
+`GIT_NAMESPACE=foo` and cloning from that repo with `GIT_NAMESPACE=bar`.  It
+also avoids ambiguity with strange namespace paths such as `foo/refs/heads/`,
+which could otherwise generate directory/file conflicts within the `refs`
+directory.
+
+linkgit:git-upload-pack[1] and linkgit:git-receive-pack[1] rewrite the
+names of refs as specified by `GIT_NAMESPACE`.  git-upload-pack and
+git-receive-pack will ignore all references outside the specified
+namespace.
+
+The smart HTTP server, linkgit:git-http-backend[1], will pass
+GIT_NAMESPACE through to the backend programs; see
+linkgit:git-http-backend[1] for sample configuration to expose
+repository namespaces as repositories.
+
+For a simple local test, you can use linkgit:git-remote-ext[1]:
+
+----------
+git clone ext::'git --namespace=foo %s /tmp/prefixed.git'

+Anyone with access to any namespace within a repository can potentially
+access objects from any other namespace stored in the same repository.
+You can't directly say "give me object ABCD" if you don't have a ref to
+it, but you can do some other sneaky things like:
+
+. Claiming to push ABCD, at which point the server will optimize out the
+  need for you to actually send it. Now you have a ref to ABCD and can
+  fetch it (claiming not to have it, of course).
+
+. Requesting other refs, claiming that you have ABCD, at which point the
+  server may generate deltas against ABCD.
+
+None of this causes a problem if you only host public repositories, or
+if everyone who may read one namespace may also read everything in every
+other namespace (for instance, if everyone in an organization has read
+permission to every repository).

+NAME
+----
+gitremote-helpers - Helper programs to interact with remote repositories
+
+SYNOPSIS
+--------
+[verse]
+'git remote-<transport>' <repository> [<URL>]
+
+DESCRIPTION
+-----------
+
+Remote helper programs are normally not used directly by end users,
+but they are invoked by Git when it needs to interact with remote
+repositories Git does not support natively.  A given helper will
+implement a subset of the capabilities documented here. When Git
+needs to interact with a repository using a remote helper, it spawns
+the helper as an independent process, sends commands to the helper's
+standard input, and expects results from the helper's standard
+output. Because a remote helper runs as an independent process from
+Git, there is no need to re-link Git to add a new helper, nor any
+need to link the helper with the implementation of Git.
+
+Every helper must support the "capabilities" command, which Git
+uses to determine what other commands the helper will accept.  Those
+other commands can be used to discover and update remote refs,
+transport objects between the object database and the remote repository,
+and update the local object store.
+
+Git comes with a "curl" family of remote helpers, that handle various
+transport protocols, such as 'git-remote-http', 'git-remote-https',
+'git-remote-ftp' and 'git-remote-ftps'. They implement the capabilities
+'fetch', 'option', and 'push'.
+
+INVOCATION
+----------
+
+Remote helper programs are invoked with one or (optionally) two
+arguments. The first argument specifies a remote repository as in Git;
+it is either the name of a configured remote or a URL. The second
+argument specifies a URL; it is usually of the form
+'<transport>://<address>', but any arbitrary string is possible.
+The 'GIT_DIR' environment variable is set up for the remote helper
+and can be used to determine where to store additional data or from
+which directory to invoke auxiliary Git commands.
+
+When Git encounters a URL of the form '<transport>://<address>', where
+'<transport>' is a protocol that it cannot handle natively, it
+automatically invokes 'git remote-<transport>' with the full URL as
+the second argument. If such a URL is encountered directly on the
+command line, the first argument is the same as the second, and if it
+is encountered in a configured remote, the first argument is the name
+of that remote.
+
+A URL of the form '<transport>::<address>' explicitly instructs Git to
+invoke 'git remote-<transport>' with '<address>' as the second
+argument. If such a URL is encountered directly on the command line,
+the first argument is '<address>', and if it is encountered in a
+configured remote, the first argument is the name of that remote.
+
+Additionally, when a configured remote has 'remote.<name>.vcs' set to
+'<transport>', Git explicitly invokes 'git remote-<transport>' with
+'<name>' as the first argument. If set, the second argument is
+'remote.<name>.url'; otherwise, the second argument is omitted.
+
+INPUT FORMAT
+------------
+
+Git sends the remote helper a list of commands on standard input, one
+per line.  The first command is always the 'capabilities' command, in
+response to which the remote helper must print a list of the
+capabilities it supports (see below) followed by a blank line.  The
+response to the capabilities command determines what commands Git uses
+in the remainder of the command stream.
+
+The command stream is terminated by a blank line.  In some cases
+(indicated in the documentation of the relevant commands), this blank
+line is followed by a payload in some other protocol (e.g., the pack
+protocol), while in others it indicates the end of input.
+
+Capabilities
+~~~~~~~~~~~~
+
+Each remote helper is expected to support only a subset of commands.
+The operations a helper supports are declared to Git in the response
+to the `capabilities` command (see COMMANDS, below).
+
+In the following, we list all defined capabilities and for
+each we list which commands a helper with that capability
+must provide.
+
+Capabilities for Pushing
+^^^^^^^^^^^^^^^^^^^^^^^^
+'connect'::
+	Can attempt to connect to 'git receive-pack' (for pushing),
+	'git upload-pack', etc for communication using
+	git's native packfile protocol. This
+	requires a bidirectional, full-duplex connection.
++
+Supported commands: 'connect'.
+
+'push'::
+	Can discover remote refs and push local commits and the
+	history leading up to them to new or existing remote refs.
++
+Supported commands: 'list for-push', 'push'.
+
+'export'::
+	Can discover remote refs and push specified objects from a
+	fast-import stream to remote refs.
++
+Supported commands: 'list for-push', 'export'.
+
+If a helper advertises 'connect', Git will use it if possible and
+fall back to another capability if the helper requests so when
+connecting (see the 'connect' command under COMMANDS).
+When choosing between 'push' and 'export', Git prefers 'push'.
+Other frontends may have some other order of preference.
+
+'no-private-update'::
+	When using the 'refspec' capability, git normally updates the
+	private ref on successful push. This update is disabled when
+	the remote-helper declares the capability 'no-private-update'.
+
+
+Capabilities for Fetching
+^^^^^^^^^^^^^^^^^^^^^^^^^
+'connect'::
+	Can try to connect to 'git upload-pack' (for fetching),
+	'git receive-pack', etc for communication using the
+	Git's native packfile protocol. This
+	requires a bidirectional, full-duplex connection.
++
+Supported commands: 'connect'.
+
+'fetch'::
+	Can discover remote refs and transfer objects reachable from
+	them to the local object store.
++
+Supported commands: 'list', 'fetch'.
+
+'import'::
+	Can discover remote refs and output objects reachable from
+	them as a stream in fast-import format.
++
+Supported commands: 'list', 'import'.
+
+'check-connectivity'::
+	Can guarantee that when a clone is requested, the received
+	pack is self contained and is connected.
+
+If a helper advertises 'connect', Git will use it if possible and
+fall back to another capability if the helper requests so when
+connecting (see the 'connect' command under COMMANDS).
+When choosing between 'fetch' and 'import', Git prefers 'fetch'.
+Other frontends may have some other order of preference.
+
+Miscellaneous capabilities
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+'option'::
+	For specifying settings like `verbosity` (how much output to
+	write to stderr) and `depth` (how much history is wanted in the
+	case of a shallow clone) that affect how other commands are
+	carried out.
+
+'refspec' <refspec>::
+	For remote helpers that implement 'import' or 'export', this capability
+	allows the refs to be constrained to a private namespace, instead of
+	writing to refs/heads or refs/remotes directly.
+	It is recommended that all importers providing the 'import'
+	capability use this. It's mandatory for 'export'.
++
+A helper advertising the capability
+`refspec refs/heads/*:refs/svn/origin/branches/*`
+is saying that, when it is asked to `import refs/heads/topic`, the
+stream it outputs will update the `refs/svn/origin/branches/topic`
+ref.
++
+This capability can be advertised multiple times.  The first
+applicable refspec takes precedence.  The left-hand of refspecs
+advertised with this capability must cover all refs reported by
+the list command.  If no 'refspec' capability is advertised,
+there is an implied `refspec *:*`.
++
+When writing remote-helpers for decentralized version control
+systems, it is advised to keep a local copy of the repository to
+interact with, and to let the private namespace refs point to this
+local repository, while the refs/remotes namespace is used to track
+the remote repository.
+
+'bidi-import'::
+	This modifies the 'import' capability.
+	The fast-import commands 'cat-blob' and 'ls' can be used by remote-helpers
+	to retrieve information about blobs and trees that already exist in
+	fast-import's memory. This requires a channel from fast-import to the
+	remote-helper.
+	If it is advertised in addition to "import", Git establishes a pipe from
+	fast-import to the remote-helper's stdin.
+	It follows that Git and fast-import are both connected to the
+	remote-helper's stdin. Because Git can send multiple commands to
+	the remote-helper it is required that helpers that use 'bidi-import'
+	buffer all 'import' commands of a batch before sending data to fast-import.
+	This is to prevent mixing commands and fast-import responses on the
+	helper's stdin.
+
+'export-marks' <file>::
+	This modifies the 'export' capability, instructing Git to dump the
+	internal marks table to <file> when complete. For details,
+	read up on '--export-marks=<file>' in linkgit:git-fast-export[1].
+
+'import-marks' <file>::
+	This modifies the 'export' capability, instructing Git to load the
+	marks specified in <file> before processing any input. For details,
+	read up on '--import-marks=<file>' in linkgit:git-fast-export[1].
+
+'signed-tags'::
+	This modifies the 'export' capability, instructing Git to pass
+	'--signed-tags=verbatim' to linkgit:git-fast-export[1].  In the
+	absence of this capability, Git will use '--signed-tags=warn-strip'.
+
+
+
+COMMANDS
+--------
+
+Commands are given by the caller on the helper's standard input, one per line.
+
+'capabilities'::
+	Lists the capabilities of the helper, one per line, ending
+	with a blank line. Each capability may be preceded with '*',
+	which marks them mandatory for Git versions using the remote
+	helper to understand. Any unknown mandatory capability is a
+	fatal error.
++
+Support for this command is mandatory.
+
+'list'::
+	Lists the refs, one per line, in the format "<value> <name>
+	[<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for
+	a symref, or "?" to indicate that the helper could not get the
+	value of the ref. A space-separated list of attributes follows
+	the name; unrecognized attributes are ignored. The list ends
+	with a blank line.
++
+See REF LIST ATTRIBUTES for a list of currently defined attributes.
++
+Supported if the helper has the "fetch" or "import" capability.
+
+'list for-push'::
+	Similar to 'list', except that it is used if and only if
+	the caller wants to the resulting ref list to prepare
+	push commands.
+	A helper supporting both push and fetch can use this
+	to distinguish for which operation the output of 'list'
+	is going to be used, possibly reducing the amount
+	of work that needs to be performed.
++
+Supported if the helper has the "push" or "export" capability.
+
+'option' <name> <value>::
+	Sets the transport helper option <name> to <value>.  Outputs a
+	single line containing one of 'ok' (option successfully set),
+	'unsupported' (option not recognized) or 'error <msg>'
+	(option <name> is supported but <value> is not valid
+	for it).  Options should be set before other commands,
+	and may influence the behavior of those commands.
++
+See OPTIONS for a list of currently defined options.
++
+Supported if the helper has the "option" capability.
+
+'fetch' <sha1> <name>::
+	Fetches the given object, writing the necessary objects
+	to the database.  Fetch commands are sent in a batch, one
+	per line, terminated with a blank line.
+	Outputs a single blank line when all fetch commands in the
+	same batch are complete. Only objects which were reported
+	in the output of 'list' with a sha1 may be fetched this way.
++
+Optionally may output a 'lock <file>' line indicating a file under
+GIT_DIR/objects/pack which is keeping a pack until refs can be
+suitably updated.
++
+If option 'check-connectivity' is requested, the helper must output
+'connectivity-ok' if the clone is self-contained and connected.
++
+Supported if the helper has the "fetch" capability.
+
+'push' +<src>:<dst>::
+	Pushes the given local <src> commit or branch to the
+	remote branch described by <dst>.  A batch sequence of
+	one or more 'push' commands is terminated with a blank line
+	(if there is only one reference to push, a single 'push' command
+	is followed by a blank line). For example, the following would
+	be two batches of 'push', the first asking the remote-helper
+	to push the local ref 'master' to the remote ref 'master' and
+	the local 'HEAD' to the remote 'branch', and the second
+	asking to push ref 'foo' to ref 'bar' (forced update requested
+	by the '+').
++
+------------
+push refs/heads/master:refs/heads/master
+push HEAD:refs/heads/branch
+\n
+push +refs/heads/foo:refs/heads/bar
+\n
+------------
++
+Zero or more protocol options may be entered after the last 'push'
+command, before the batch's terminating blank line.
++
+When the push is complete, outputs one or more 'ok <dst>' or
+'error <dst> <why>?' lines to indicate success or failure of
+each pushed ref.  The status report output is terminated by
+a blank line.  The option field <why> may be quoted in a C
+style string if it contains an LF.
++
+Supported if the helper has the "push" capability.
+
+'import' <name>::
+	Produces a fast-import stream which imports the current value
+	of the named ref. It may additionally import other refs as
+	needed to construct the history efficiently. The script writes
+	to a helper-specific private namespace. The value of the named
+	ref should be written to a location in this namespace derived
+	by applying the refspecs from the "refspec" capability to the
+	name of the ref.
++
+Especially useful for interoperability with a foreign versioning
+system.
++
+Just like 'push', a batch sequence of one or more 'import' is
+terminated with a blank line. For each batch of 'import', the remote
+helper should produce a fast-import stream terminated by a 'done'
+command.
++
+Note that if the 'bidi-import' capability is used the complete batch
+sequence has to be buffered before starting to send data to fast-import
+to prevent mixing of commands and fast-import responses on the helper's
+stdin.
++
+Supported if the helper has the "import" capability.
+
+'export'::
+	Instructs the remote helper that any subsequent input is
+	part of a fast-import stream (generated by 'git fast-export')
+	containing objects which should be pushed to the remote.
++
+Especially useful for interoperability with a foreign versioning
+system.
++
+The 'export-marks' and 'import-marks' capabilities, if specified,
+affect this command in so far as they are passed on to 'git
+fast-export', which then will load/store a table of marks for
+local objects. This can be used to implement for incremental
+operations.
++
+Supported if the helper has the "export" capability.
+
+'connect' <service>::
+	Connects to given service. Standard input and standard output
+	of helper are connected to specified service (git prefix is
+	included in service name so e.g. fetching uses 'git-upload-pack'
+	as service) on remote side. Valid replies to this command are
+	empty line (connection established), 'fallback' (no smart
+	transport support, fall back to dumb transports) and just
+	exiting with error message printed (can't connect, don't
+	bother trying to fall back). After line feed terminating the
+	positive (empty) response, the output of service starts. After
+	the connection ends, the remote helper exits.
++
+Supported if the helper has the "connect" capability.
+
+If a fatal error occurs, the program writes the error message to
+stderr and exits. The caller should expect that a suitable error
+message has been printed if the child closes the connection without
+completing a valid response for the current command.
+
+Additional commands may be supported, as may be determined from
+capabilities reported by the helper.
+
+REF LIST ATTRIBUTES
+-------------------
+
+The 'list' command produces a list of refs in which each ref
+may be followed by a list of attributes. The following ref list
+attributes are defined.
+
+'unchanged'::
+	This ref is unchanged since the last import or fetch, although
+	the helper cannot necessarily determine what value that produced.
+
+OPTIONS
+-------
+
+The following options are defined and (under suitable circumstances)
+set by Git if the remote helper has the 'option' capability.
+
+'option verbosity' <n>::
+	Changes the verbosity of messages displayed by the helper.
+	A value of 0 for <n> means that processes operate
+	quietly, and the helper produces only error output.
+	1 is the default level of verbosity, and higher values
+	of <n> correspond to the number of -v flags passed on the
+	command line.
+
+'option progress' {'true'|'false'}::
+	Enables (or disables) progress messages displayed by the
+	transport helper during a command.
+
+'option depth' <depth>::
+	Deepens the history of a shallow repository.
+
+'option followtags' {'true'|'false'}::
+	If enabled the helper should automatically fetch annotated
+	tag objects if the object the tag points at was transferred
+	during the fetch command.  If the tag is not fetched by
+	the helper a second fetch command will usually be sent to
+	ask for the tag specifically.  Some helpers may be able to
+	use this option to avoid a second network connection.
+
+'option dry-run' {'true'|'false'}:
+	If true, pretend the operation completed successfully,
+	but don't actually change any repository data.	For most
+	helpers this only applies to the 'push', if supported.
+
+'option servpath <c-style-quoted-path>'::
+	Sets service path (--upload-pack, --receive-pack etc.) for
+	next connect. Remote helper may support this option, but
+	must not rely on this option being set before
+	connect request occurs.
+
+'option check-connectivity' {'true'|'false'}::
+	Request the helper to check connectivity of a clone.
+
+'option force' {'true'|'false'}::
+	Request the helper to perform a force update.  Defaults to
+	'false'.
+
+'option cloning {'true'|'false'}::
+	Notify the helper this is a clone request (i.e. the current
+	repository is guaranteed empty).
+
+'option update-shallow {'true'|'false'}::
+	Allow to extend .git/shallow if the new refs require it.
+
+'option pushcert {'true'|'false'}::
+	GPG sign pushes.

+=======================
+
+NAME
+----
+gitrepository-layout - Git Repository Layout
+
+SYNOPSIS
+--------
+$GIT_DIR/*
+
+DESCRIPTION
+-----------
+
+A Git repository comes in two different flavours:
+
+ * a `.git` directory at the root of the working tree;
+
+ * a `<project>.git` directory that is a 'bare' repository
+   (i.e. without its own working tree), that is typically used for
+   exchanging histories with others by pushing into it and fetching
+   from it.
+
+*Note*: Also you can have a plain text file `.git` at the root of
+your working tree, containing `gitdir: <path>` to point at the real
+directory that has the repository.  This mechanism is often used for
+a working tree of a submodule checkout, to allow you in the
+containing superproject to `git checkout` a branch that does not
+have the submodule.  The `checkout` has to remove the entire
+submodule working tree, without losing the submodule repository.
+
+These things may exist in a Git repository.
+
+objects::
+	Object store associated with this repository.  Usually
+	an object store is self sufficient (i.e. all the objects
+	that are referred to by an object found in it are also
+	found in it), but there are a few ways to violate it.
++
+. You could have an incomplete but locally usable repository
+by creating a shallow clone.  See linkgit:git-clone[1].
+. You could be using the `objects/info/alternates` or
+`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanisms to 'borrow'
+objects from other object stores.  A repository with this kind
+of incomplete object store is not suitable to be published for
+use with dumb transports but otherwise is OK as long as
+`objects/info/alternates` points at the object stores it
+borrows from.
++
+This directory is ignored if $GIT_COMMON_DIR is set and
+"$GIT_COMMON_DIR/objects" will be used instead.
+
+objects/[0-9a-f][0-9a-f]::
+	A newly created object is stored in its own file.
+	The objects are splayed over 256 subdirectories using
+	the first two characters of the sha1 object name to
+	keep the number of directory entries in `objects`
+	itself to a manageable number. Objects found
+	here are often called 'unpacked' (or 'loose') objects.
+
+objects/pack::
+	Packs (files that store many object in compressed form,
+	along with index files to allow them to be randomly
+	accessed) are found in this directory.
+
+objects/info::
+	Additional information about the object store is
+	recorded in this directory.
+
+objects/info/packs::
+	This file is to help dumb transports discover what packs
+	are available in this object store.  Whenever a pack is
+	added or removed, `git update-server-info` should be run
+	to keep this file up-to-date if the repository is
+	published for dumb transports.  'git repack' does this
+	by default.
+
+objects/info/alternates::
+	This file records paths to alternate object stores that
+	this object store borrows objects from, one pathname per
+	line. Note that not only native Git tools use it locally,
+	but the HTTP fetcher also tries to use it remotely; this
+	will usually work if you have relative paths (relative
+	to the object database, not to the repository!) in your
+	alternates file, but it will not work if you use absolute
+	paths unless the absolute path in filesystem and web URL
+	is the same. See also 'objects/info/http-alternates'.
+
+objects/info/http-alternates::
+	This file records URLs to alternate object stores that
+	this object store borrows objects from, to be used when
+	the repository is fetched over HTTP.
+
+refs::
+	References are stored in subdirectories of this
+	directory.  The 'git prune' command knows to preserve
+	objects reachable from refs found in this directory and
+	its subdirectories. This directory is ignored if $GIT_COMMON_DIR
+	is set and "$GIT_COMMON_DIR/refs" will be used instead.
+
+refs/heads/`name`::
+	records tip-of-the-tree commit objects of branch `name`
+
+refs/tags/`name`::
+	records any object name (not necessarily a commit
+	object, or a tag object that points at a commit object).
+
+refs/remotes/`name`::
+	records tip-of-the-tree commit objects of branches copied
+	from a remote repository.
+
+refs/replace/`<obj-sha1>`::
+	records the SHA-1 of the object that replaces `<obj-sha1>`.
+	This is similar to info/grafts and is internally used and
+	maintained by linkgit:git-replace[1]. Such refs can be exchanged
+	between repositories while grafts are not.
+
+packed-refs::
+	records the same information as refs/heads/, refs/tags/,
+	and friends record in a more efficient way.  See
+	linkgit:git-pack-refs[1]. This file is ignored if $GIT_COMMON_DIR
+	is set and "$GIT_COMMON_DIR/packed-refs" will be used instead.
+
+HEAD::
+	A symref (see glossary) to the `refs/heads/` namespace
+	describing the currently active branch.  It does not mean
+	much if the repository is not associated with any working tree
+	(i.e. a 'bare' repository), but a valid Git repository
+	*must* have the HEAD file; some porcelains may use it to
+	guess the designated "default" branch of the repository
+	(usually 'master').  It is legal if the named branch
+	'name' does not (yet) exist.  In some legacy setups, it is
+	a symbolic link instead of a symref that points at the current
+	branch.
++
+HEAD can also record a specific commit directly, instead of
+being a symref to point at the current branch.  Such a state
+is often called 'detached HEAD.'  See linkgit:git-checkout[1]
+for details.
+
+config::
+	Repository specific configuration file. This file is ignored
+	if $GIT_COMMON_DIR is set and "$GIT_COMMON_DIR/config" will be
+	used instead.
+
+branches::
+	A slightly deprecated way to store shorthands to be used
+	to specify a URL to 'git fetch', 'git pull' and 'git push'.
+	A file can be stored as `branches/<name>` and then
+	'name' can be given to these commands in place of
+	'repository' argument.  See the REMOTES section in
+	linkgit:git-fetch[1] for details.  This mechanism is legacy
+	and not likely to be found in modern repositories. This
+	directory is ignored if $GIT_COMMON_DIR is set and
+	"$GIT_COMMON_DIR/branches" will be used instead.
+
+
+hooks::
+	Hooks are customization scripts used by various Git
+	commands.  A handful of sample hooks are installed when
+	'git init' is run, but all of them are disabled by
+	default.  To enable, the `.sample` suffix has to be
+	removed from the filename by renaming.
+	Read linkgit:githooks[5] for more details about
+	each hook. This directory is ignored if $GIT_COMMON_DIR is set
+	and "$GIT_COMMON_DIR/hooks" will be used instead.
+
+
+index::
+	The current index file for the repository.  It is
+	usually not found in a bare repository.
+
+sharedindex.<SHA-1>::
+	The shared index part, to be referenced by $GIT_DIR/index and
+	other temporary index files. Only valid in split index mode.
+
+info::
+	Additional information about the repository is recorded
+	in this directory. This directory is ignored if $GIT_COMMON_DIR
+	is set and "$GIT_COMMON_DIR/index" will be used instead.
+
+info/refs::
+	This file helps dumb transports discover what refs are
+	available in this repository.  If the repository is
+	published for dumb transports, this file should be
+	regenerated by 'git update-server-info' every time a tag
+	or branch is created or modified.  This is normally done
+	from the `hooks/update` hook, which is run by the
+	'git-receive-pack' command when you 'git push' into the
+	repository.
+
+info/grafts::
+	This file records fake commit ancestry information, to
+	pretend the set of parents a commit has is different
+	from how the commit was actually created.  One record
+	per line describes a commit and its fake parents by
+	listing their 40-byte hexadecimal object names separated
+	by a space and terminated by a newline.
++
+Note that the grafts mechanism is outdated and can lead to problems
+transferring objects between repositories; see linkgit:git-replace[1]
+for a more flexible and robust system to do the same thing.
+
+info/exclude::
+	This file, by convention among Porcelains, stores the
+	exclude pattern list. `.gitignore` is the per-directory
+	ignore file.  'git status', 'git add', 'git rm' and
+	'git clean' look at it but the core Git commands do not look
+	at it.  See also: linkgit:gitignore[5].
+
+info/sparse-checkout::
+	This file stores sparse checkout patterns.
+	See also: linkgit:git-read-tree[1].
+
+remotes::
+	Stores shorthands for URL and default refnames for use
+	when interacting with remote repositories via 'git fetch',
+	'git pull' and 'git push' commands.  See the REMOTES section
+	in linkgit:git-fetch[1] for details.  This mechanism is legacy
+	and not likely to be found in modern repositories. This
+	directory is ignored if $GIT_COMMON_DIR is set and
+	"$GIT_COMMON_DIR/remotes" will be used instead.
+
+logs::
+	Records of changes made to refs are stored in this directory.
+	See linkgit:git-update-ref[1] for more information. This
+	directory is ignored if $GIT_COMMON_DIR is set and
+	"$GIT_COMMON_DIR/logs" will be used instead.
+
+logs/refs/heads/`name`::
+	Records all changes made to the branch tip named `name`.
+
+logs/refs/tags/`name`::
+	Records all changes made to the tag named `name`.
+
+shallow::
+	This is similar to `info/grafts` but is internally used
+	and maintained by shallow clone mechanism.  See `--depth`
+	option to linkgit:git-clone[1] and linkgit:git-fetch[1]. This
+	file is ignored if $GIT_COMMON_DIR is set and
+	"$GIT_COMMON_DIR/shallow" will be used instead.
+
+commondir::
+	If this file exists, $GIT_COMMON_DIR (see linkgit:git[1]) will
+	be set to the path specified in this file if it is not
+	explicitly set. If the specified path is relative, it is
+	relative to $GIT_DIR. The repository with commondir is
+	incomplete without the repository pointed by "commondir".
+
+modules::
+	Contains the git-repositories of the submodules.
+
+worktrees::
+	Contains administrative data for linked
+	working trees. Each subdirectory contains the working tree-related
+	part of a linked working tree. This directory is ignored if
+	$GIT_COMMON_DIR is set, in which case
+	"$GIT_COMMON_DIR/worktrees" will be used instead.
+
+worktrees/<id>/gitdir::
+	A text file containing the absolute path back to the .git file
+	that points to here. This is used to check if the linked
+	repository has been manually removed and there is no need to
+	keep this directory any more. The mtime of this file should be
+	updated every time the linked repository is accessed.
+
+worktrees/<id>/locked::
+	If this file exists, the linked working tree may be on a
+	portable device and not available. The presence of this file
+	prevents `worktrees/<id>` from being pruned either automatically
+	or manually by `git worktree prune`. The file may contain a string
+	explaining why the repository is locked.
+
+worktrees/<id>/link::
+	If this file exists, it is a hard link to the linked .git
+	file. It is used to detect if the linked repository is
+	manually removed.

+gitrevisions - specifying revisions and ranges for Git
+
+SYNOPSIS
+--------
+gitrevisions
+
+
+DESCRIPTION
+-----------
+
+Many Git commands take revision parameters as arguments. Depending on
+the command, they denote a specific commit or, for commands which
+walk the revision graph (such as linkgit:git-log[1]), all commits which can
+be reached from that commit. In the latter case one can also specify a
+range of revisions explicitly.
+
+In addition, some Git commands (such as linkgit:git-show[1]) also take
+revision parameters which denote other objects than commits, e.g. blobs
+("files") or trees ("directories of files").

+================
+
+NAME
+----
+gittutorial-2 - A tutorial introduction to Git: part two
+
+SYNOPSIS
+--------
+[verse]
+git *
+
+DESCRIPTION
+-----------
+
+You should work through linkgit:gittutorial[7] before reading this tutorial.
+
+The goal of this tutorial is to introduce two fundamental pieces of
+Git's architecture--the object database and the index file--and to
+provide the reader with everything necessary to understand the rest
+of the Git documentation.
+
+The Git object database
+-----------------------
+
+Let's start a new project and create a small amount of history:
+
+------------------------------------------------
+$ mkdir test-project
+$ cd test-project
+$ git init
+Initialized empty Git repository in .git/
+$ echo 'hello world' > file.txt
+$ git add .
+$ git commit -a -m "initial commit"
+[master (root-commit) 54196cc] initial commit
+ 1 file changed, 1 insertion(+)
+ create mode 100644 file.txt
+$ echo 'hello world!' >file.txt
+$ git commit -a -m "add emphasis"
+[master c4d59f3] add emphasis
+ 1 file changed, 1 insertion(+), 1 deletion(-)
+------------------------------------------------
+
+What are the 7 digits of hex that Git responded to the commit with?
+
+We saw in part one of the tutorial that commits have names like this.
+It turns out that every object in the Git history is stored under
+a 40-digit hex name.  That name is the SHA-1 hash of the object's
+contents; among other things, this ensures that Git will never store
+the same data twice (since identical data is given an identical SHA-1
+name), and that the contents of a Git object will never change (since
+that would change the object's name as well). The 7 char hex strings
+here are simply the abbreviation of such 40 character long strings.
+Abbreviations can be used everywhere where the 40 character strings
+can be used, so long as they are unambiguous.
+
+It is expected that the content of the commit object you created while
+following the example above generates a different SHA-1 hash than
+the one shown above because the commit object records the time when
+it was created and the name of the person performing the commit.
+
+We can ask Git about this particular object with the `cat-file`
+command. Don't copy the 40 hex digits from this example but use those
+from your own version. Note that you can shorten it to only a few
+characters to save yourself typing all 40 hex digits:
+
+------------------------------------------------
+$ git cat-file -t 54196cc2
+commit
+$ git cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+
+initial commit
+------------------------------------------------
+
+A tree can refer to one or more "blob" objects, each corresponding to
+a file.  In addition, a tree can also refer to other tree objects,
+thus creating a directory hierarchy.  You can examine the contents of
+any tree using ls-tree (remember that a long enough initial portion
+of the SHA-1 will also work):
+
+------------------------------------------------
+$ git ls-tree 92b8b694
+100644 blob 3b18e512dba79e4c8300dd08aeb37f8e728b8dad    file.txt
+------------------------------------------------
+
+Thus we see that this tree has one file in it.  The SHA-1 hash is a
+reference to that file's data:
+
+------------------------------------------------
+$ git cat-file -t 3b18e512
+blob
+------------------------------------------------
+
+A "blob" is just file data, which we can also examine with cat-file:
+
+------------------------------------------------
+$ git cat-file blob 3b18e512
+hello world
+------------------------------------------------
+
+Note that this is the old file data; so the object that Git named in
+its response to the initial tree was a tree with a snapshot of the
+directory state that was recorded by the first commit.
+
+All of these objects are stored under their SHA-1 names inside the Git
+directory:
+
+------------------------------------------------
+$ find .git/objects/
+.git/objects/
+.git/objects/pack
+.git/objects/info
+.git/objects/3b
+.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad
+.git/objects/92
+.git/objects/92/b8b694ffb1675e5975148e1121810081dbdffe
+.git/objects/54
+.git/objects/54/196cc2703dc165cbd373a65a4dcf22d50ae7f7
+.git/objects/a0
+.git/objects/a0/423896973644771497bdc03eb99d5281615b51
+.git/objects/d0
+.git/objects/d0/492b368b66bdabf2ac1fd8c92b39d3db916e59
+.git/objects/c4
+.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
+------------------------------------------------
+
+and the contents of these files is just the compressed data plus a
+header identifying their length and their type.  The type is either a
+blob, a tree, a commit, or a tag.
+
+The simplest commit to find is the HEAD commit, which we can find
+from .git/HEAD:
+
+------------------------------------------------
+$ cat .git/HEAD
+ref: refs/heads/master
+------------------------------------------------
+
+As you can see, this tells us which branch we're currently on, and it
+tells us this by naming a file under the .git directory, which itself
+contains a SHA-1 name referring to a commit object, which we can
+examine with cat-file:
+
+------------------------------------------------
+$ cat .git/refs/heads/master
+c4d59f390b9cfd4318117afde11d601c1085f241
+$ git cat-file -t c4d59f39
+commit
+$ git cat-file commit c4d59f39
+tree d0492b368b66bdabf2ac1fd8c92b39d3db916e59
+parent 54196cc2703dc165cbd373a65a4dcf22d50ae7f7

+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
+
+add emphasis
+------------------------------------------------
+
+The "tree" object here refers to the new state of the tree:
+
+------------------------------------------------
+$ git ls-tree d0492b36
+100644 blob a0423896973644771497bdc03eb99d5281615b51    file.txt
+$ git cat-file blob a0423896
+hello world!
+------------------------------------------------
+
+and the "parent" object refers to the previous commit:
+
+------------------------------------------------
+$ git cat-file commit 54196cc2
+tree 92b8b694ffb1675e5975148e1121810081dbdffe
+author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
+
+initial commit
+------------------------------------------------
+
+The tree object is the tree we examined first, and this commit is
+unusual in that it lacks any parent.
+
+Most commits have only one parent, but it is also common for a commit
+to have multiple parents.   In that case the commit represents a
+merge, with the parent references pointing to the heads of the merged
+branches.
+
+Besides blobs, trees, and commits, the only remaining type of object
+is a "tag", which we won't discuss here; refer to linkgit:git-tag[1]
+for details.
+
+So now we know how Git uses the object database to represent a
+project's history:
+
+  * "commit" objects refer to "tree" objects representing the
+    snapshot of a directory tree at a particular point in the
+    history, and refer to "parent" commits to show how they're
+    connected into the project history.
+  * "tree" objects represent the state of a single directory,
+    associating directory names to "blob" objects containing file
+    data and "tree" objects containing subdirectory information.
+  * "blob" objects contain file data without any other structure.
+  * References to commit objects at the head of each branch are
+    stored in files under .git/refs/heads/.
+  * The name of the current branch is stored in .git/HEAD.
+
+Note, by the way, that lots of commands take a tree as an argument.
+But as we can see above, a tree can be referred to in many different
+ways--by the SHA-1 name for that tree, by the name of a commit that
+refers to the tree, by the name of a branch whose head refers to that
+tree, etc.--and most such commands can accept any of these names.
+
+In command synopses, the word "tree-ish" is sometimes used to
+designate such an argument.
+
+The index file
+--------------
+
+The primary tool we've been using to create commits is `git-commit
+-a`, which creates a commit including every change you've made to
+your working tree.  But what if you want to commit changes only to
+certain files?  Or only certain changes to certain files?
+
+If we look at the way commits are created under the cover, we'll see
+that there are more flexible ways creating commits.
+
+Continuing with our test-project, let's modify file.txt again:
+
+------------------------------------------------
+$ echo "hello world, again" >>file.txt
+------------------------------------------------
+
+but this time instead of immediately making the commit, let's take an
+intermediate step, and ask for diffs along the way to keep track of
+what's happening:
+
+------------------------------------------------
+$ git diff
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+$ git add file.txt
+$ git diff
+------------------------------------------------
+
+The last diff is empty, but no new commits have been made, and the
+head still doesn't contain the new line:
+
+------------------------------------------------
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..513feba 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+So 'git diff' is comparing against something other than the head.
+The thing that it's comparing against is actually the index file,
+which is stored in .git/index in a binary format, but whose contents
+we can examine with ls-files:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
+$ git cat-file -t 513feba2
+blob
+$ git cat-file blob 513feba2
+hello world!
+hello world, again
+------------------------------------------------
+
+So what our 'git add' did was store a new blob and then put
+a reference to it in the index file.  If we modify the file again,
+we'll see that the new modifications are reflected in the 'git diff'
+output:
+
+------------------------------------------------
+$ echo 'again?' >>file.txt
+$ git diff
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+With the right arguments, 'git diff' can also show us the difference
+between the working directory and the last commit, or between the
+index and the last commit:
+
+------------------------------------------------
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index a042389..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,3 @@
+ hello world!
++hello world, again
++again?
+$ git diff --cached
+diff --git a/file.txt b/file.txt

+--- a/file.txt
++++ b/file.txt
+@@ -1 +1,2 @@
+ hello world!
++hello world, again
+------------------------------------------------
+
+At any time, we can create a new commit using 'git commit' (without
+the "-a" option), and verify that the state committed only includes the
+changes stored in the index file, not the additional change that is
+still only in our working tree:
+
+------------------------------------------------
+$ git commit -m "repeat"
+$ git diff HEAD
+diff --git a/file.txt b/file.txt
+index 513feba..ba3da7b 100644
+--- a/file.txt
++++ b/file.txt
+@@ -1,2 +1,3 @@
+ hello world!
+ hello world, again
++again?
+------------------------------------------------
+
+So by default 'git commit' uses the index to create the commit, not
+the working tree; the "-a" option to commit tells it to first update
+the index with all changes in the working tree.
+
+Finally, it's worth looking at the effect of 'git add' on the index
+file:
+
+------------------------------------------------
+$ echo "goodbye, world" >closing.txt
+$ git add closing.txt
+------------------------------------------------
+
+The effect of the 'git add' was to add one entry to the index file:
+
+------------------------------------------------
+$ git ls-files --stage
+100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0       closing.txt
+100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
+------------------------------------------------
+
+And, as you can see with cat-file, this new entry refers to the
+current contents of the file:
+
+------------------------------------------------
+$ git cat-file blob 8b9743b2
+goodbye, world
+------------------------------------------------
+
+The "status" command is a useful way to get a quick summary of the
+situation:
+
+------------------------------------------------
+$ git status
+On branch master
+Changes to be committed:
+  (use "git reset HEAD <file>..." to unstage)
+
+	new file:   closing.txt
+
+Changes not staged for commit:
+  (use "git add <file>..." to update what will be committed)
+  (use "git checkout -- <file>..." to discard changes in working directory)
+
+	modified:   file.txt
+
+------------------------------------------------
+
+Since the current state of closing.txt is cached in the index file,
+it is listed as "Changes to be committed".  Since file.txt has
+changes in the working directory that aren't reflected in the index,
+it is marked "changed but not updated".  At this point, running "git
+commit" would create a commit that added closing.txt (with its new
+contents), but that didn't modify file.txt.
+
+Also, note that a bare `git diff` shows the changes to file.txt, but
+not the addition of closing.txt, because the version of closing.txt
+in the index file is identical to the one in the working directory.
+
+In addition to being the staging area for new commits, the index file
+is also populated from the object database when checking out a
+branch, and is used to hold the trees involved in a merge operation.
+See linkgit:gitcore-tutorial[7] and the relevant man
+pages for details.
+
+What next?
+----------
+
+At this point you should know everything necessary to read the man
+pages for any of the git commands; one good place to start would be
+with the commands mentioned in linkgit:giteveryday[7].  You
+should be able to find any unknown jargon in linkgit:gitglossary[7].
+
+The link:user-manual.html[Git User's Manual] provides a more
+comprehensive introduction to Git.
+
+linkgit:gitcvs-migration[7] explains how to
+import a CVS repository into Git, and shows how to use Git in a
+CVS-like way.
+
+For some interesting examples of Git use, see the
+link:howto-index.html[howtos].
+
+For Git developers, linkgit:gitcore-tutorial[7] goes

+NAME
+----
+gittutorial - A tutorial introduction to Git
+
+SYNOPSIS
+--------
+[verse]
+git *
+
+DESCRIPTION
+-----------
+
+This tutorial explains how to import a new project into Git, make
+changes to it, and share changes with other developers.
+
+If you are instead primarily interested in using Git to fetch a project,
+for example, to test the latest version, you may prefer to start with
+the first two chapters of link:user-manual.html[The Git User's Manual].
+
+First, note that you can get documentation for a command such as
+`git log --graph` with:
+
+------------------------------------------------
+$ man git-log
+------------------------------------------------
+
+or:
+
+------------------------------------------------
+$ git help log
+------------------------------------------------
+
+With the latter, you can use the manual viewer of your choice; see
+linkgit:git-help[1] for more information.
+
+It is a good idea to introduce yourself to Git with your name and
+public email address before doing any operation.  The easiest
+way to do so is:
+
+------------------------------------------------
+$ git config --global user.name "Your Name Comes Here"
+$ git config --global user.email you@yourdomain.example.com
+------------------------------------------------
+
+
+Importing a new project
+-----------------------
+
+Assume you have a tarball project.tar.gz with your initial work.  You
+can place it under Git revision control as follows.
+
+------------------------------------------------
+$ tar xzf project.tar.gz
+$ cd project
+$ git init
+------------------------------------------------
+
+Git will reply
+
+------------------------------------------------
+Initialized empty Git repository in .git/
+------------------------------------------------
+
+You've now initialized the working directory--you may notice a new
+directory created, named ".git".
+
+Next, tell Git to take a snapshot of the contents of all files under the
+current directory (note the '.'), with 'git add':
+
+------------------------------------------------
+$ git add .
+------------------------------------------------
+
+This snapshot is now stored in a temporary staging area which Git calls
+the "index".  You can permanently store the contents of the index in the
+repository with 'git commit':
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+This will prompt you for a commit message.  You've now stored the first
+version of your project in Git.
+
+Making changes
+--------------
+
+Modify some files, then add their updated contents to the index:
+
+------------------------------------------------
+$ git add file1 file2 file3
+------------------------------------------------
+
+You are now ready to commit.  You can see what is about to be committed
+using 'git diff' with the --cached option:
+
+------------------------------------------------
+$ git diff --cached
+------------------------------------------------
+
+(Without --cached, 'git diff' will show you any changes that
+you've made but not yet added to the index.)  You can also get a brief
+summary of the situation with 'git status':
+
+------------------------------------------------
+$ git status
+On branch master
+Changes to be committed:
+Your branch is up-to-date with 'origin/master'.
+  (use "git reset HEAD <file>..." to unstage)
+
+	modified:   file1
+	modified:   file2
+	modified:   file3
+
+------------------------------------------------
+
+If you need to make any further adjustments, do so now, and then add any
+newly modified content to the index.  Finally, commit your changes with:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+This will again prompt you for a message describing the change, and then
+record a new version of the project.
+
+Alternatively, instead of running 'git add' beforehand, you can use
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+which will automatically notice any modified (but not new) files, add
+them to the index, and commit, all in one step.
+
+A note on commit messages: Though not required, it's a good idea to
+begin the commit message with a single short (less than 50 character)
+line summarizing the change, followed by a blank line and then a more
+thorough description. The text up to the first blank line in a commit
+message is treated as the commit title, and that title is used
+throughout Git.  For example, linkgit:git-format-patch[1] turns a
+commit into email, and it uses the title on the Subject line and the
+rest of the commit in the body.
+
+Git tracks content not files
+----------------------------
+
+Many revision control systems provide an `add` command that tells the
+system to start tracking changes to a new file.  Git's `add` command
+does something simpler and more powerful: 'git add' is used both for new
+and newly modified files, and in both cases it takes a snapshot of the
+given files and stages that content in the index, ready for inclusion in
+the next commit.
+
+Viewing project history
+-----------------------
+
+At any point you can view the history of your changes using
+
+------------------------------------------------
+$ git log
+------------------------------------------------
+
+If you also want to see complete diffs at each step, use
+
+------------------------------------------------
+$ git log -p
+------------------------------------------------
+
+Often the overview of the change is useful to get a feel of
+each step
+
+------------------------------------------------
+$ git log --stat --summary
+------------------------------------------------
+
+Managing branches
+-----------------
+
+A single Git repository can maintain multiple branches of
+development.  To create a new branch named "experimental", use
+
+------------------------------------------------
+$ git branch experimental
+------------------------------------------------
+
+If you now run
+
+------------------------------------------------
+$ git branch
+------------------------------------------------
+
+you'll get a list of all existing branches:
+
+------------------------------------------------
+  experimental
+* master
+------------------------------------------------
+
+The "experimental" branch is the one you just created, and the
+"master" branch is a default branch that was created for you
+automatically.  The asterisk marks the branch you are currently on;
+type
+
+------------------------------------------------
+$ git checkout experimental
+------------------------------------------------
+
+to switch to the experimental branch.  Now edit a file, commit the
+change, and switch back to the master branch:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+$ git checkout master
+------------------------------------------------
+
+Check that the change you made is no longer visible, since it was
+made on the experimental branch and you're back on the master branch.
+
+You can make a different change on the master branch:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+------------------------------------------------
+
+at this point the two branches have diverged, with different changes
+made in each.  To merge the changes made in experimental into master, run
+
+------------------------------------------------
+$ git merge experimental
+------------------------------------------------
+
+If the changes don't conflict, you're done.  If there are conflicts,
+markers will be left in the problematic files showing the conflict;
+
+------------------------------------------------
+$ git diff
+------------------------------------------------
+
+will show this.  Once you've edited the files to resolve the
+conflicts,
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+will commit the result of the merge. Finally,
+
+------------------------------------------------
+$ gitk
+------------------------------------------------
+
+will show a nice graphical representation of the resulting history.
+
+At this point you could delete the experimental branch with
+
+------------------------------------------------
+$ git branch -d experimental
+------------------------------------------------
+
+This command ensures that the changes in the experimental branch are
+already in the current branch.
+
+If you develop on a branch crazy-idea, then regret it, you can always
+delete the branch with
+
+-------------------------------------
+$ git branch -D crazy-idea
+-------------------------------------
+
+Branches are cheap and easy, so this is a good way to try something
+out.
+
+Using Git for collaboration
+---------------------------
+
+Suppose that Alice has started a new project with a Git repository in
+/home/alice/project, and that Bob, who has a home directory on the
+same machine, wants to contribute.
+
+Bob begins with:
+
+------------------------------------------------
+bob$ git clone /home/alice/project myrepo
+------------------------------------------------
+
+This creates a new directory "myrepo" containing a clone of Alice's
+repository.  The clone is on an equal footing with the original
+project, possessing its own copy of the original project's history.
+
+Bob then makes some changes and commits them:
+
+------------------------------------------------
+(edit files)
+bob$ git commit -a
+(repeat as necessary)
+------------------------------------------------
+
+When he's ready, he tells Alice to pull changes from the repository
+at /home/bob/myrepo.  She does this with:
+
+------------------------------------------------
+alice$ cd /home/alice/project
+alice$ git pull /home/bob/myrepo master
+------------------------------------------------
+
+This merges the changes from Bob's "master" branch into Alice's
+current branch.  If Alice has made her own changes in the meantime,
+then she may need to manually fix any conflicts.
+
+The "pull" command thus performs two operations: it fetches changes
+from a remote branch, then merges them into the current branch.
+
+Note that in general, Alice would want her local changes committed before
+initiating this "pull".  If Bob's work conflicts with what Alice did since
+their histories forked, Alice will use her working tree and the index to
+resolve conflicts, and existing local changes will interfere with the
+conflict resolution process (Git will still perform the fetch but will
+refuse to merge --- Alice will have to get rid of her local changes in
+some way and pull again when this happens).
+
+Alice can peek at what Bob did without merging first, using the "fetch"
+command; this allows Alice to inspect what Bob did, using a special
+symbol "FETCH_HEAD", in order to determine if he has anything worth
+pulling, like this:
+
+------------------------------------------------
+alice$ git fetch /home/bob/myrepo master
+alice$ git log -p HEAD..FETCH_HEAD
+------------------------------------------------
+
+This operation is safe even if Alice has uncommitted local changes.
+The range notation "HEAD..FETCH_HEAD" means "show everything that is reachable
+from the FETCH_HEAD but exclude anything that is reachable from HEAD".
+Alice already knows everything that leads to her current state (HEAD),
+and reviews what Bob has in his state (FETCH_HEAD) that she has not
+seen with this command.
+
+If Alice wants to visualize what Bob did since their histories forked
+she can issue the following command:
+
+------------------------------------------------
+$ gitk HEAD..FETCH_HEAD
+------------------------------------------------
+
+This uses the same two-dot range notation we saw earlier with 'git log'.
+
+Alice may want to view what both of them did since they forked.
+She can use three-dot form instead of the two-dot form:
+
+------------------------------------------------
+$ gitk HEAD...FETCH_HEAD
+------------------------------------------------
+
+This means "show everything that is reachable from either one, but
+exclude anything that is reachable from both of them".
+
+Please note that these range notation can be used with both gitk
+and "git log".
+
+After inspecting what Bob did, if there is nothing urgent, Alice may
+decide to continue working without pulling from Bob.  If Bob's history
+does have something Alice would immediately need, Alice may choose to
+stash her work-in-progress first, do a "pull", and then finally unstash
+her work-in-progress on top of the resulting history.
+
+When you are working in a small closely knit group, it is not
+unusual to interact with the same repository over and over
+again.  By defining 'remote' repository shorthand, you can make
+it easier:
+
+------------------------------------------------
+alice$ git remote add bob /home/bob/myrepo
+------------------------------------------------
+
+With this, Alice can perform the first part of the "pull" operation
+alone using the 'git fetch' command without merging them with her own
+branch, using:
+
+-------------------------------------
+alice$ git fetch bob
+-------------------------------------
+
+Unlike the longhand form, when Alice fetches from Bob using a
+remote repository shorthand set up with 'git remote', what was
+fetched is stored in a remote-tracking branch, in this case
+`bob/master`.  So after this:
+
+-------------------------------------
+alice$ git log -p master..bob/master
+-------------------------------------
+
+shows a list of all the changes that Bob made since he branched from
+Alice's master branch.
+
+After examining those changes, Alice
+could merge the changes into her master branch:
+
+-------------------------------------
+alice$ git merge bob/master
+-------------------------------------
+
+This `merge` can also be done by 'pulling from her own remote-tracking
+branch', like this:
+
+-------------------------------------
+alice$ git pull . remotes/bob/master
+-------------------------------------
+
+Note that git pull always merges into the current branch,
+regardless of what else is given on the command line.
+
+Later, Bob can update his repo with Alice's latest changes using
+
+-------------------------------------
+bob$ git pull
+-------------------------------------
+
+Note that he doesn't need to give the path to Alice's repository;
+when Bob cloned Alice's repository, Git stored the location of her
+repository in the repository configuration, and that location is
+used for pulls:
+
+-------------------------------------
+bob$ git config --get remote.origin.url
+/home/alice/project
+-------------------------------------
+
+(The complete configuration created by 'git clone' is visible using
+`git config -l`, and the linkgit:git-config[1] man page
+explains the meaning of each option.)
+
+Git also keeps a pristine copy of Alice's master branch under the
+name "origin/master":
+
+-------------------------------------
+bob$ git branch -r
+  origin/master
+-------------------------------------
+
+If Bob later decides to work from a different host, he can still
+perform clones and pulls using the ssh protocol:
+
+-------------------------------------
+bob$ git clone alice.org:/home/alice/project myrepo
+-------------------------------------
+
+Alternatively, Git has a native protocol, or can use rsync or http;
+see linkgit:git-pull[1] for details.
+
+Git can also be used in a CVS-like mode, with a central repository
+that various users push changes to; see linkgit:git-push[1] and
+linkgit:gitcvs-migration[7].
+
+Exploring history
+-----------------
+
+Git history is represented as a series of interrelated commits.  We
+have already seen that the 'git log' command can list those commits.
+Note that first line of each git log entry also gives a name for the
+commit:
+
+-------------------------------------
+$ git log
+commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+Author: Junio C Hamano <junkio@cox.net>
+Date:   Tue May 16 17:18:22 2006 -0700
+
+    merge-base: Clarify the comments on post processing.
+-------------------------------------
+
+We can give this name to 'git show' to see the details about this
+commit.
+
+-------------------------------------
+$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+-------------------------------------
+
+But there are other ways to refer to commits.  You can use any initial
+part of the name that is long enough to uniquely identify the commit:
+
+-------------------------------------
+$ git show c82a22c39c	# the first few characters of the name are
+			# usually enough
+$ git show HEAD		# the tip of the current branch
+$ git show experimental	# the tip of the "experimental" branch
+-------------------------------------
+
+Every commit usually has one "parent" commit
+which points to the previous state of the project:
+
+-------------------------------------
+$ git show HEAD^  # to see the parent of HEAD
+$ git show HEAD^^ # to see the grandparent of HEAD
+$ git show HEAD~4 # to see the great-great grandparent of HEAD
+-------------------------------------
+
+Note that merge commits may have more than one parent:
+
+-------------------------------------
+$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
+$ git show HEAD^2 # show the second parent of HEAD
+-------------------------------------
+
+You can also give commits names of your own; after running
+
+-------------------------------------
+$ git tag v2.5 1b2e1d63ff
+-------------------------------------
+
+you can refer to 1b2e1d63ff by the name "v2.5".  If you intend to
+share this name with other people (for example, to identify a release
+version), you should create a "tag" object, and perhaps sign it; see
+linkgit:git-tag[1] for details.
+
+Any Git command that needs to know a commit can take any of these
+names.  For example:
+
+-------------------------------------
+$ git diff v2.5 HEAD	 # compare the current HEAD to v2.5
+$ git branch stable v2.5 # start a new branch named "stable" based
+			 # at v2.5
+$ git reset --hard HEAD^ # reset your current branch and working
+			 # directory to its state at HEAD^
+-------------------------------------
+
+Be careful with that last command: in addition to losing any changes
+in the working directory, it will also remove all later commits from
+this branch.  If this branch is the only branch containing those
+commits, they will be lost.  Also, don't use 'git reset' on a
+publicly-visible branch that other developers pull from, as it will
+force needless merges on other developers to clean up the history.
+If you need to undo changes that you have pushed, use 'git revert'
+instead.
+
+The 'git grep' command can search for strings in any version of your
+project, so
+
+-------------------------------------
+$ git grep "hello" v2.5
+-------------------------------------
+
+searches for all occurrences of "hello" in v2.5.
+
+If you leave out the commit name, 'git grep' will search any of the
+files it manages in your current directory.  So
+
+-------------------------------------
+$ git grep "hello"
+-------------------------------------
+
+is a quick way to search just the files that are tracked by Git.
+
+Many Git commands also take sets of commits, which can be specified
+in a number of ways.  Here are some examples with 'git log':
+
+-------------------------------------
+$ git log v2.5..v2.6            # commits between v2.5 and v2.6
+$ git log v2.5..                # commits since v2.5
+$ git log --since="2 weeks ago" # commits from the last 2 weeks
+$ git log v2.5.. Makefile       # commits since v2.5 which modify
+				# Makefile
+-------------------------------------
+
+You can also give 'git log' a "range" of commits where the first is not
+necessarily an ancestor of the second; for example, if the tips of
+the branches "stable" and "master" diverged from a common
+commit some time ago, then
+
+-------------------------------------
+$ git log stable..master
+-------------------------------------
+
+will list commits made in the master branch but not in the
+stable branch, while
+
+-------------------------------------
+$ git log master..stable
+-------------------------------------
+
+will show the list of commits made on the stable branch but not
+the master branch.
+
+The 'git log' command has a weakness: it must present commits in a
+list.  When the history has lines of development that diverged and
+then merged back together, the order in which 'git log' presents
+those commits is meaningless.
+
+Most projects with multiple contributors (such as the Linux kernel,
+or Git itself) have frequent merges, and 'gitk' does a better job of
+visualizing their history.  For example,
+
+-------------------------------------
+$ gitk --since="2 weeks ago" drivers/
+-------------------------------------
+
+allows you to browse any commits from the last 2 weeks of commits
+that modified files under the "drivers" directory.  (Note: you can
+adjust gitk's fonts by holding down the control key while pressing
+"-" or "+".)
+
+Finally, most commands that take filenames will optionally allow you
+to precede any filename by a commit, to specify a particular version
+of the file:
+
+-------------------------------------
+$ git diff v2.5:Makefile HEAD:Makefile.in
+-------------------------------------
+
+You can also use 'git show' to see any such file:
+
+-------------------------------------
+$ git show v2.5:Makefile
+-------------------------------------
+
+Next Steps
+----------
+
+This tutorial should be enough to perform basic distributed revision
+control for your projects.  However, to fully understand the depth
+and power of Git you need to understand two simple ideas on which it
+is based:
+
+  * The object database is the rather elegant system used to
+    store the history of your project--files, directories, and
+    commits.
+
+  * The index file is a cache of the state of a directory tree,
+    used to create commits, check out working directories, and
+    hold the various trees involved in a merge.
+
+Part two of this tutorial explains the object
+database, the index file, and a few other odds and ends that you'll
+need to make the most of Git. You can find it at linkgit:gittutorial-2[7].
+
+If you don't want to continue with that right away, a few other
+digressions that may be interesting at this point are:
+
+  * linkgit:git-format-patch[1], linkgit:git-am[1]: These convert
+    series of git commits into emailed patches, and vice versa,
+    useful for projects such as the Linux kernel which rely heavily
+    on emailed patches.
+
+  * linkgit:git-bisect[1]: When there is a regression in your
+    project, one way to track down the bug is by searching through
+    the history to find the exact commit that's to blame.  Git bisect
+    can help you perform a binary search for that commit.  It is
+    smart enough to perform a close-to-optimal search even in the
+    case of complex non-linear history with lots of merged branches.
+
+  * linkgit:gitworkflows[7]: Gives an overview of recommended
+    workflows.
+
+  * linkgit:giteveryday[7]: Everyday Git with 20 Commands Or So.
+
+  * linkgit:gitcvs-migration[7]: Git for CVS users.

+
+NAME
+----
+gitweb.conf - Gitweb (Git web interface) configuration file
+
+SYNOPSIS
+--------
+/etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl
+
+DESCRIPTION
+-----------
+
+The gitweb CGI script for viewing Git repositories over the web uses a
+perl script fragment as its configuration file.  You can set variables
+using "`our $variable = value`"; text from a "#" character until the
+end of a line is ignored.  See *perlsyn*(1) for details.
+
+An example:
+
+    # gitweb configuration file for http://git.example.org
+    #
+    our $projectroot = "/srv/git"; # FHS recommendation
+    our $site_name = 'Example.org >> Repos';
+
+
+The configuration file is used to override the default settings that
+were built into gitweb at the time the 'gitweb.cgi' script was generated.
+
+While one could just alter the configuration settings in the gitweb
+CGI itself, those changes would be lost upon upgrade.  Configuration
+settings might also be placed into a file in the same directory as the
+CGI script with the default name 'gitweb_config.perl' -- allowing
+one to have multiple gitweb instances with different configurations by
+the use of symlinks.
+
+Note that some configuration can be controlled on per-repository rather than
+gitweb-wide basis: see "Per-repository gitweb configuration" subsection on
+linkgit:gitweb[1] manpage.
+
+
+DISCUSSION
+----------
+Gitweb reads configuration data from the following sources in the
+following order:
+
+ * built-in values (some set during build stage),
+
+ * common system-wide configuration file (defaults to
+   '/etc/gitweb-common.conf'),
+
+ * either per-instance configuration file (defaults to 'gitweb_config.perl'
+   in the same directory as the installed gitweb), or if it does not exists
+   then fallback system-wide configuration file (defaults to '/etc/gitweb.conf').
+
+Values obtained in later configuration files override values obtained earlier
+in the above sequence.
+
+Locations of the common system-wide configuration file, the fallback
+system-wide configuration file and the per-instance configuration file
+are defined at compile time using build-time Makefile configuration
+variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM`
+and `GITWEB_CONFIG`.
+
+You can also override locations of gitweb configuration files during
+runtime by setting the following environment variables:
+`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG`
+to a non-empty value.
+
+
+The syntax of the configuration files is that of Perl, since these files are
+handled by sourcing them as fragments of Perl code (the language that
+gitweb itself is written in). Variables are typically set using the
+`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax
+errors if a new version of gitweb no longer uses a variable and therefore
+stops declaring it.
+
+You can include other configuration file using read_config_file()
+subroutine.  For example, one might want to put gitweb configuration
+related to access control for viewing repositories via Gitolite (one
+of Git repository management tools) in a separate file, e.g. in
+'/etc/gitweb-gitolite.conf'.  To include it, put
+
+--------------------------------------------------
+read_config_file("/etc/gitweb-gitolite.conf");
+--------------------------------------------------
+
+somewhere in gitweb configuration file used, e.g. in per-installation
+gitweb configuration file.  Note that read_config_file() checks itself
+that the file it reads exists, and does nothing if it is not found.
+It also handles errors in included file.
+
+
+The default configuration with no configuration file at all may work
+perfectly well for some installations.  Still, a configuration file is
+useful for customizing or tweaking the behavior of gitweb in many ways, and
+some optional features will not be present unless explicitly enabled using
+the configurable `%features` variable (see also "Configuring gitweb
+features" section below).
+
+
+CONFIGURATION VARIABLES
+-----------------------
+Some configuration variables have their default values (embedded in the CGI
+script) set during building gitweb -- if that is the case, this fact is put
+in their description.  See gitweb's 'INSTALL' file for instructions on building
+and installing gitweb.
+
+
+Location of repositories
+~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below control how gitweb finds
+Git repositories, and how repositories are displayed and accessed.
+
+See also "Repositories" and later subsections in linkgit:gitweb[1] manpage.
+
+$projectroot::
+	Absolute filesystem path which will be prepended to project path;
+	the path to repository is `$projectroot/$project`.  Set to
+	`$GITWEB_PROJECTROOT` during installation.  This variable has to be
+	set correctly for gitweb to find repositories.
++
+For example, if `$projectroot` is set to "/srv/git" by putting the following
+in gitweb config file:
++
+----------------------------------------------------------------------------
+our $projectroot = "/srv/git";
+----------------------------------------------------------------------------
++
+then
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi?p=foo/bar.git
+------------------------------------------------
++
+and its path_info based equivalent
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi/foo/bar.git
+------------------------------------------------
++
+will map to the path '/srv/git/foo/bar.git' on the filesystem.
+
+$projects_list::
+	Name of a plain text file listing projects, or a name of directory
+	to be scanned for projects.
++
+Project list files should list one project per line, with each line
+having the following format
++
+-----------------------------------------------------------------------------
+<URI-encoded filesystem path to repository> SP <URI-encoded repository owner>
+-----------------------------------------------------------------------------
++
+The default value of this variable is determined by the `GITWEB_LIST`
+makefile variable at installation time.  If this variable is empty, gitweb
+will fall back to scanning the `$projectroot` directory for repositories.
+
+$project_maxdepth::
+	If `$projects_list` variable is unset, gitweb will recursively
+	scan filesystem for Git repositories.  The `$project_maxdepth`
+	is used to limit traversing depth, relative to `$projectroot`
+	(starting point); it means that directories which are further
+	from `$projectroot` than `$project_maxdepth` will be skipped.
++
+It is purely performance optimization, originally intended for MacOS X,
+where recursive directory traversal is slow.  Gitweb follows symbolic
+links, but it detects cycles, ignoring any duplicate files and directories.
++
+The default value of this variable is determined by the build-time
+configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to
+2007.
+
+$export_ok::
+	Show repository only if this file exists (in repository).  Only
+	effective if this variable evaluates to true.  Can be set when
+	building gitweb by setting `GITWEB_EXPORT_OK`.  This path is
+	relative to `GIT_DIR`.  git-daemon[1] uses 'git-daemon-export-ok',
+	unless started with `--export-all`.  By default this variable is
+	not set, which means that this feature is turned off.
+
+$export_auth_hook::
+	Function used to determine which repositories should be shown.
+	This subroutine should take one parameter, the full path to
+	a project, and if it returns true, that project will be included
+	in the projects list and can be accessed through gitweb as long
+	as it fulfills the other requirements described by $export_ok,
+	$projects_list, and $projects_maxdepth.  Example:
++
+----------------------------------------------------------------------------
+our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; };
+----------------------------------------------------------------------------
++
+though the above might be done by using `$export_ok` instead
++
+----------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+----------------------------------------------------------------------------
++
+If not set (default), it means that this feature is disabled.
++
+See also more involved example in "Controlling access to Git repositories"
+subsection on linkgit:gitweb[1] manpage.
+
+$strict_export::
+	Only allow viewing of repositories also shown on the overview page.
+	This for example makes `$gitweb_export_ok` file decide if repository is
+	available and not only if it is shown.  If `$gitweb_list` points to
+	file with list of project, only those repositories listed would be
+	available for gitweb.  Can be set during building gitweb via
+	`GITWEB_STRICT_EXPORT`.  By default this variable is not set, which
+	means that you can directly access those repositories that are hidden
+	from projects list page (e.g. the are not listed in the $projects_list
+	file).
+
+
+Finding files
+~~~~~~~~~~~~~
+The following configuration variables tell gitweb where to find files.
+The values of these variables are paths on the filesystem.
+
+$GIT::
+	Core git executable to use.  By default set to `$GIT_BINDIR/git`, which
+	in turn is by default set to `$(bindir)/git`.  If you use Git installed
+	from a binary package, you should usually set this to "/usr/bin/git".
+	This can just be "git" if your web server has a sensible PATH; from
+	security point of view it is better to use absolute path to git binary.
+	If you have multiple Git versions installed it can be used to choose
+	which one to use.  Must be (correctly) set for gitweb to be able to
+	work.
+
+$mimetypes_file::
+	File to use for (filename extension based) guessing of MIME types before
+	trying '/etc/mime.types'.  *NOTE* that this path, if relative, is taken
+	as relative to the current Git repository, not to CGI script.  If unset,
+	only '/etc/mime.types' is used (if present on filesystem).  If no mimetypes
+	file is found, mimetype guessing based on extension of file is disabled.
+	Unset by default.
+
+$highlight_bin::
+	Path to the highlight executable to use (it must be the one from
+	http://www.andre-simon.de[] due to assumptions about parameters and output).
+	By default set to 'highlight'; set it to full path to highlight
+	executable if it is not installed on your web server's PATH.
+	Note that 'highlight' feature must be set for gitweb to actually
+	use syntax highlighting.
++
+*NOTE*: if you want to add support for new file type (supported by
+"highlight" but not used by gitweb), you need to modify `%highlight_ext`
+or `%highlight_basename`, depending on whether you detect type of file
+based on extension (for example "sh") or on its basename (for example
+"Makefile").  The keys of these hashes are extension and basename,
+respectively, and value for given key is name of syntax to be passed via
+`--syntax <syntax>` to highlighter.
++
+For example if repositories you are hosting use "phtml" extension for
+PHP files, and you want to have correct syntax-highlighting for those
+files, you can add the following to gitweb configuration:
++
+---------------------------------------------------------
+our %highlight_ext;
+$highlight_ext{'phtml'} = 'php';
+---------------------------------------------------------
+
+
+Links and their targets
+~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below configure some of gitweb links:
+their target and their look (text or image), and where to find page
+prerequisites (stylesheet, favicon, images, scripts).  Usually they are left
+at their default values, with the possible exception of `@stylesheets`
+variable.
+
+@stylesheets::
+	List of URIs of stylesheets (relative to the base URI of a page). You
+	might specify more than one stylesheet, for example to use "gitweb.css"
+	as base with site specific modifications in a separate stylesheet
+	to make it easier to upgrade gitweb.  For example, you can add
+	a `site` stylesheet by putting
++
+----------------------------------------------------------------------------
+push @stylesheets, "gitweb-site.css";
+----------------------------------------------------------------------------
++
+in the gitweb config file.  Those values that are relative paths are
+relative to base URI of gitweb.
++
+This list should contain the URI of gitweb's standard stylesheet.  The default
+URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS`
+makefile variable.  Its default value is 'static/gitweb.css'
+(or 'static/gitweb.min.css' if the `CSSMIN` variable is defined,
+i.e. if CSS minifier is used during build).
++
+*Note*: there is also a legacy `$stylesheet` configuration variable, which was
+used by older gitweb.  If `$stylesheet` variable is defined, only CSS stylesheet
+given by this variable is used by gitweb.
+
+$logo::
+	Points to the location where you put 'git-logo.png' on your web
+	server, or to be more the generic URI of logo, 72x27 size).  This image
+	is displayed in the top right corner of each gitweb page and used as
+	a logo for the Atom feed.  Relative to the base URI of gitweb (as a path).
+	Can be adjusted when building gitweb using `GITWEB_LOGO` variable
+	By default set to 'static/git-logo.png'.
+
+$favicon::
+	Points to the location where you put 'git-favicon.png' on your web
+	server, or to be more the generic URI of favicon, which will be served
+	as "image/png" type.  Web browsers that support favicons (website icons)
+	may display them in the browser's URL bar and next to the site name in
+	bookmarks.  Relative to the base URI of gitweb.  Can be adjusted at
+	build time using `GITWEB_FAVICON` variable.
+	By default set to 'static/git-favicon.png'.
+
+$javascript::
+	Points to the location where you put 'gitweb.js' on your web server,
+	or to be more generic the URI of JavaScript code used by gitweb.
+	Relative to the base URI of gitweb.  Can be set at build time using
+	the `GITWEB_JS` build-time configuration variable.
++
+The default value is either 'static/gitweb.js', or 'static/gitweb.min.js' if
+the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used
+at build time.  *Note* that this single file is generated from multiple
+individual JavaScript "modules".
+
+$home_link::
+	Target of the home link on the top of all pages (the first part of view
+	"breadcrumbs").  By default it is set to the absolute URI of a current page
+	(to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined
+	or is an empty string).
+
+$home_link_str::
+	Label for the "home link" at the top of all pages, leading to `$home_link`
+	(usually the main gitweb page, which contains the projects list).  It is
+	used as the first component of gitweb's "breadcrumb trail":
+	`<home link> / <project> / <action>`.  Can be set at build time using
+	the `GITWEB_HOME_LINK_STR` variable.  By default it is set to "projects",
+	as this link leads to the list of projects.  Another popular choice is to
+	set it to the name of site.  Note that it is treated as raw HTML so it
+	should not be set from untrusted sources.
+
+@extra_breadcrumbs::
+	Additional links to be added to the start of the breadcrumb trail before
+	the home link, to pages that are logically "above" the gitweb projects
+	list, such as the organization and department which host the gitweb
+	server. Each element of the list is a reference to an array, in which
+	element 0 is the link text (equivalent to `$home_link_str`) and element
+	1 is the target URL (equivalent to `$home_link`).
++
+For example, the following setting produces a breadcrumb trail like
+"home / dev / projects / ..." where "projects" is the home link.
+----------------------------------------------------------------------------
+    our @extra_breadcrumbs = (
+      [ 'home' => 'https://www.example.org/' ],
+      [ 'dev'  => 'https://dev.example.org/' ],
+    );
+----------------------------------------------------------------------------
+
+$logo_url::
+$logo_label::
+	URI and label (title) for the Git logo link (or your site logo,
+	if you chose to use different logo image). By default, these both
+	refer to Git homepage, http://git-scm.com[]; in the past, they pointed
+	to Git documentation at http://www.kernel.org[].
+
+
+Changing gitweb's look
+~~~~~~~~~~~~~~~~~~~~~~
+You can adjust how pages generated by gitweb look using the variables described
+below.  You can change the site name, add common headers and footers for all
+pages, and add a description of this gitweb installation on its main page
+(which is the projects list page), etc.
+
+$site_name::
+	Name of your site or organization, to appear in page titles.  Set it
+	to something descriptive for clearer bookmarks etc.  If this variable
+	is not set or is, then gitweb uses the value of the `SERVER_NAME`
+	CGI environment variable, setting site name to "$SERVER_NAME Git",
+	or "Untitled Git" if this variable is not set (e.g. if running gitweb
+	as standalone script).
++
+Can be set using the `GITWEB_SITENAME` at build time.  Unset by default.
+
+$site_html_head_string::
+	HTML snippet to be included in the <head> section of each page.
+	Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time.
+	No default value.
+
+$site_header::
+	Name of a file with HTML to be included at the top of each page.
+	Relative to the directory containing the 'gitweb.cgi' script.
+	Can be set using `GITWEB_SITE_HEADER` at build time.  No default
+	value.
+
+$site_footer::
+	Name of a file with HTML to be included at the bottom of each page.
+	Relative to the directory containing the 'gitweb.cgi' script.
+	Can be set using `GITWEB_SITE_FOOTER` at build time.  No default
+	value.
+
+$home_text::
+	Name of a HTML file which, if it exists, is included on the
+	gitweb projects overview page ("projects_list" view).  Relative to
+	the directory containing the gitweb.cgi script.  Default value
+	can be adjusted during build time using `GITWEB_HOMETEXT` variable.
+	By default set to 'indextext.html'.
+
+$projects_list_description_width::
+	The width (in characters) of the "Description" column of the projects list.
+	Longer descriptions will be truncated (trying to cut at word boundary);
+	the full description is available in the 'title' attribute (usually shown on
+	mouseover).  The default is 25, which might be too small if you
+	use long project descriptions.
+
+$default_projects_order::
+	Default value of ordering of projects on projects list page, which
+	means the ordering used if you don't explicitly sort projects list
+	(if there is no "o" CGI query parameter in the URL).  Valid values
+	are "none" (unsorted), "project" (projects are by project name,
+	i.e. path to repository relative to `$projectroot`), "descr"
+	(project description), "owner", and "age" (by date of most current
+	commit).
++
+Default value is "project".  Unknown value means unsorted.
+
+
+Changing gitweb's behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+These configuration variables control _internal_ gitweb behavior.
+
+$default_blob_plain_mimetype::
+	Default mimetype for the blob_plain (raw) view, if mimetype checking
+	doesn't result in some other type; by default "text/plain".
+	Gitweb guesses mimetype of a file to display based on extension
+	of its filename, using `$mimetypes_file` (if set and file exists)
+	and '/etc/mime.types' files (see *mime.types*(5) manpage; only
+	filename extension rules are supported by gitweb).
+
+$default_text_plain_charset::
+	Default charset for text files. If this is not set, the web server
+	configuration will be used.  Unset by default.
+
+$fallback_encoding::
+	Gitweb assumes this charset when a line contains non-UTF-8 characters.
+	The fallback decoding is used without error checking, so it can be even
+	"utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm)
+	man page for a list. The default is "latin1", aka. "iso-8859-1".
+
+@diff_opts::
+	Rename detection options for git-diff and git-diff-tree. The default is
+	(\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies,
+	or set it to () i.e. empty list if you don't want to have renames
+	detection.
++
+*Note* that rename and especially copy detection can be quite
+CPU-intensive.  Note also that non Git tools can have problems with
+patches generated with options mentioned above, especially when they
+involve file copies (\'-C') or criss-cross renames (\'-B').
+
+
+Some optional features and policies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most of features are configured via `%feature` hash; however some of extra
+gitweb features can be turned on and configured using variables described
+below.  This list beside configuration variables that control how gitweb
+looks does contain variables configuring administrative side of gitweb
+(e.g. cross-site scripting prevention; admittedly this as side effect
+affects how "summary" pages look like, or load limiting).
+
+@git_base_url_list::
+	List of Git base URLs.  These URLs are used to generate URLs
+	describing from where to fetch a project, which are shown on
+	project summary page.  The full fetch URL is "`$git_base_url/$project`",
+	for each element of this list. You can set up multiple base URLs
+	(for example one for `git://` protocol, and one for `http://`
+	protocol).
++
+Note that per repository configuration can be set in '$GIT_DIR/cloneurl'
+file, or as values of multi-value `gitweb.url` configuration variable in
+project config.  Per-repository configuration takes precedence over value
+composed from `@git_base_url_list` elements and project name.
++
+You can setup one single value (single entry/item in this list) at build
+time by setting the `GITWEB_BASE_URL` build-time configuration variable.
+By default it is set to (), i.e. an empty list.  This means that gitweb
+would not try to create project URL (to fetch) from project name.
+
+$projects_list_group_categories::
+	Whether to enable the grouping of projects by category on the project
+	list page. The category of a project is determined by the
+	`$GIT_DIR/category` file or the `gitweb.category` variable in each
+	repository's configuration.  Disabled by default (set to 0).
+
+$project_list_default_category::
+	Default category for projects for which none is specified.  If this is
+	set to the empty string, such projects will remain uncategorized and
+	listed at the top, above categorized projects.  Used only if project
+	categories are enabled, which means if `$projects_list_group_categories`
+	is true.  By default set to "" (empty string).
+
+$prevent_xss::
+	If true, some gitweb features are disabled to prevent content in
+	repositories from launching cross-site scripting (XSS) attacks.  Set this
+	to true if you don't trust the content of your repositories.
+	False by default (set to 0).
+
+$maxload::
+	Used to set the maximum load that we will still respond to gitweb queries.
+	If the server load exceeds this value then gitweb will return
+	"503 Service Unavailable" error.  The server load is taken to be 0
+	if gitweb cannot determine its value.  Currently it works only on Linux,
+	where it uses '/proc/loadavg'; the load there is the number of active
+	tasks on the system -- processes that are actually running -- averaged
+	over the last minute.
++
+Set `$maxload` to undefined value (`undef`) to turn this feature off.
+The default value is 300.
+
+$omit_age_column::
+	If true, omit the column with date of the most current commit on the
+	projects list page. It can save a bit of I/O and a fork per repository.
+
+$omit_owner::
+	If true prevents displaying information about repository owner.
+
+$per_request_config::
+	If this is set to code reference, it will be run once for each request.
+	You can	set parts of configuration that change per session this way.
+	For example, one might use the following code in a gitweb configuration
+	file
++
+--------------------------------------------------------------------------------
+our $per_request_config = sub {
+	$ENV{GL_USER} = $cgi->remote_user || "gitweb";
+};
+--------------------------------------------------------------------------------
++
+If `$per_request_config` is not a code reference, it is interpreted as boolean
+value.  If it is true gitweb will process config files once per request,
+and if it is false gitweb will process config files only once, each time it
+is executed.  True by default (set to 1).
++
+*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default
+values before every request, so if you want to change them, be sure to set
+this variable to true or a code reference effecting the desired changes.
++
+This variable matters only when using persistent web environments that
+serve multiple requests using single gitweb instance, like mod_perl,
+FastCGI or Plackup.
+
+
+Other variables
+~~~~~~~~~~~~~~~
+Usually you should not need to change (adjust) any of configuration
+variables described below; they should be automatically set by gitweb to
+correct value.
+
+
+$version::
+	Gitweb version, set automatically when creating gitweb.cgi from
+	gitweb.perl. You might want to modify it if you are running modified
+	gitweb, for example
++
+---------------------------------------------------
+our $version .= " with caching";
+---------------------------------------------------
++
+if you run modified version of gitweb with caching support.  This variable
+is purely informational, used e.g. in the "generator" meta header in HTML
+header.
+
+$my_url::
+$my_uri::
+	Full URL and absolute URL of the gitweb script;
+	in earlier versions of gitweb you might have need to set those
+	variables, but now there should be no need to do it.  See
+	`$per_request_config` if you need to set them still.
+
+$base_url::
+	Base URL for relative URLs in pages generated by gitweb,
+	(e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs),
+	needed and used '<base href="$base_url">' only for URLs with nonempty
+	PATH_INFO.  Usually gitweb sets its value correctly,
+	and there is no need to set this variable, e.g. to $my_uri or "/".
+	See `$per_request_config` if you need to override it anyway.
+
+
+CONFIGURING GITWEB FEATURES
+---------------------------
+Many gitweb features can be enabled (or disabled) and configured using the
+`%feature` hash.  Names of gitweb features are keys of this hash.
+
+Each `%feature` hash element is a hash reference and has the following
+structure:
+----------------------------------------------------------------------
+"<feature_name>" => {
+	"sub" => <feature-sub (subroutine)>,
+	"override" => <allow-override (boolean)>,
+	"default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+Some features cannot be overridden per project.  For those
+features the structure of appropriate `%feature` hash element has a simpler
+form:
+----------------------------------------------------------------------
+"<feature_name>" => {
+	"override" => 0,
+	"default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+As one can see it lacks the \'sub' element.
+
+The meaning of each part of feature configuration is described
+below:
+
+default::
+	List (array reference) of feature parameters (if there are any),
+	used also to toggle (enable or disable) given feature.
++
+Note that it is currently *always* an array reference, even if
+feature doesn't accept any configuration parameters, and \'default'
+is used only to turn it on or off.  In such case you turn feature on
+by setting this element to `[1]`, and torn it off by setting it to
+`[0]`.  See also the passage about the "blame" feature in the "Examples"
+section.
++
+To disable features that accept parameters (are configurable), you
+need to set this element to empty list i.e. `[]`.
+
+override::
+	If this field has a true value then the given feature is
+	overridable, which means that it can be configured
+	(or enabled/disabled) on a per-repository basis.
++
+Usually given "<feature>" is configurable via the `gitweb.<feature>`
+config variable in the per-repository Git configuration file.
++
+*Note* that no feature is overridable by default.
+
+sub::
+	Internal detail of implementation.  What is important is that
+	if this field is not present then per-repository override for
+	given feature is not supported.
++
+You wouldn't need to ever change it in gitweb config file.
+
+
+Features in `%feature`
+~~~~~~~~~~~~~~~~~~~~~~
+The gitweb features that are configurable via `%feature` hash are listed
+below.  This should be a complete list, but ultimately the authoritative
+and complete list is in gitweb.cgi source code, with features described
+in the comments.
+
+blame::
+	Enable the "blame" and "blame_incremental" blob views, showing for
+	each line the last commit that modified it; see linkgit:git-blame[1].
+	This can be very CPU-intensive and is therefore disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable (boolean).
+
+snapshot::
+	Enable and configure the "snapshot" action, which allows user to
+	download a compressed archive of any tree or commit, as produced
+	by linkgit:git-archive[1] and possibly additionally compressed.
+	This can potentially generate high traffic if you have large project.
++
+The value of \'default' is a list of names of snapshot formats,
+defined in `%known_snapshot_formats` hash, that you wish to offer.
+Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz
+compressed tar archive) and "zip"; please consult gitweb sources for
+a definitive list.  By default only "tgz" is offered.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable, which contains
+a comma separated list of formats or "none" to disable snapshots.
+Unknown values are ignored.
+
+grep::
+	Enable grep search, which lists the files in currently selected
+	tree (directory) containing the given string; see linkgit:git-grep[1].
+	This can be potentially CPU-intensive, of course.  Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.grep` configuration variable (boolean).
+
+pickaxe::
+	Enable the so called pickaxe search, which will list the commits
+	that introduced or removed a given string in a file.  This can be
+	practical and quite faster alternative to "blame" action, but it is
+	still potentially CPU-intensive.  Enabled by default.
++
+The pickaxe search is described in linkgit:git-log[1] (the
+description of `-S<string>` option, which refers to pickaxe entry in
+linkgit:gitdiffcore[7] for more details).
++
+This feature can be configured on a per-repository basis by setting
+repository's `gitweb.pickaxe` configuration variable (boolean).
+
+show-sizes::
+	Enable showing size of blobs (ordinary files) in a "tree" view, in a
+	separate column, similar to what `ls -l` does; see description of
+	`-l` option in linkgit:git-ls-tree[1] manpage.  This costs a bit of
+	I/O.  Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.showSizes` configuration variable (boolean).
+
+patches::
+	Enable and configure "patches" view, which displays list of commits in email
+	(plain text) output format; see also linkgit:git-format-patch[1].
+	The value is the maximum number of patches in a patchset generated
+	in "patches" view.  Set the 'default' field to a list containing single
+	item of or to an empty list to disable patch view, or to a list
+	containing a single negative number to remove any limit.
+	Default value is 16.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.patches` configuration variable (integer).
+
+avatar::
+	Avatar support.  When this feature is enabled, views such as
+	"shortlog" or "commit" will display an avatar associated with
+	the email of each committer and author.
++
+Currently available providers are *"gravatar"* and *"picon"*.
+Only one provider at a time can be selected ('default' is one element list).
+If an unknown provider is specified, the feature is disabled.
+*Note* that some providers might require extra Perl packages to be
+installed; see 'gitweb/INSTALL' for more details.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.avatar` configuration variable.
++
+See also `%avatar_size` with pixel sizes for icons and avatars
+("default" is used for one-line like "log" and "shortlog", "double"
+is used for two-line like "commit", "commitdiff" or "tag").  If the
+default font sizes or lineheights are changed (e.g. via adding extra
+CSS stylesheet in `@stylesheets`), it may be appropriate to change
+these values.
+
+highlight::
+	Server-side syntax highlight support in "blob" view.  It requires
+	`$highlight_bin` program to be available (see the description of
+	this variable in the "Configuration variables" section above),
+	and therefore is disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.highlight` configuration variable (boolean).
+
+remote_heads::
+	Enable displaying remote heads (remote-tracking branches) in the "heads"
+	list.  In most cases the list of remote-tracking branches is an
+	unnecessary internal private detail, and this feature is therefore
+	disabled by default.  linkgit:git-instaweb[1], which is usually used
+	to browse local repositories, enables and uses this feature.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.remote_heads` configuration variable (boolean).
+
+
+The remaining features cannot be overridden on a per project basis.
+
+search::
+	Enable text search, which will list the commits which match author,
+	committer or commit text to a given string; see the description of
+	`--author`, `--committer` and `--grep` options in linkgit:git-log[1]
+	manpage.  Enabled by default.
++
+Project specific override is not supported.
+
+forks::
+	If this feature is enabled, gitweb considers projects in
+	subdirectories of project root (basename) to be forks of existing
+	projects.  For each project +$projname.git+, projects in the
+	+$projname/+ directory and its subdirectories will not be
+	shown in the main projects list.  Instead, a \'\+' mark is shown
+	next to +$projname+, which links to a "forks" view that lists all
+	the forks (all projects in +$projname/+ subdirectory).  Additionally
+	a "forks" view for a project is linked from project summary page.
++
+If the project list is taken from a file (+$projects_list+ points to a
+file), forks are only recognized if they are listed after the main project
+in that file.
++
+Project specific override is not supported.
+
+actions::
+	Insert custom links to the action bar of all project pages.  This
+	allows you to link to third-party scripts integrating into gitweb.
++
+The "default" value consists of a list of triplets in the form
+`("<label>", "<link>", "<position>")` where "position" is the label
+after which to insert the link, "link" is a format string where `%n`
+expands to the project name, `%f` to the project path within the
+filesystem (i.e. "$projectroot/$project"), `%h` to the current hash
+(\'h' gitweb parameter) and `%b` to the current hash base
+(\'hb' gitweb parameter); `%%` expands to \'%'.
++
+For example, at the time this page was written, the http://repo.or.cz[]
+Git hosting site set it to the following to enable graphical log
+(using the third party tool *git-browser*):
++
+----------------------------------------------------------------------
+$feature{'actions'}{'default'} =
+	[ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')];
+----------------------------------------------------------------------
++
+This adds a link titled "graphiclog" after the "summary" link, leading to
+`git-browser` script, passing `r=<project>` as a query parameter.
++
+Project specific override is not supported.
+
+timed::
+	Enable displaying how much time and how many Git commands it took to
+	generate and display each page in the page footer (at the bottom of
+	page).  For example the footer might contain: "This page took 6.53325
+	seconds and 13 Git commands to generate."  Disabled by default.
++
+Project specific override is not supported.
+
+javascript-timezone::
+	Enable and configure the ability to change a common time zone for dates
+	in gitweb output via JavaScript.  Dates in gitweb output include
+	authordate and committerdate in "commit", "commitdiff" and "log"
+	views, and taggerdate in "tag" view.  Enabled by default.
++
+The value is a list of three values: a default time zone (for if the client
+hasn't selected some other time zone and saved it in a cookie), a name of cookie
+where to store selected time zone, and a CSS class used to mark up
+dates for manipulation.  If you want to turn this feature off, set "default"
+to empty list: `[]`.
++
+Typical gitweb config files will only change starting (default) time zone,
+and leave other elements at their default values:
++
+---------------------------------------------------------------------------
+$feature{'javascript-timezone'}{'default'}[0] = "utc";
+---------------------------------------------------------------------------
++
+The example configuration presented here is guaranteed to be backwards
+and forward compatible.
++
+Time zone values can be "local" (for local time zone that browser uses), "utc"
+(what gitweb uses when JavaScript or this feature is disabled), or numerical
+time zones in the form of "+/-HHMM", such as "+0200".
++
+Project specific override is not supported.
+
+extra-branch-refs::
+	List of additional directories under "refs" which are going to
+	be used as branch refs. For example if you have a gerrit setup
+	where all branches under refs/heads/ are official,
+	push-after-review ones and branches under refs/sandbox/,
+	refs/wip and refs/other are user ones where permissions are
+	much wider, then you might want to set this variable as
+	follows:
++
+--------------------------------------------------------------------------------
+$feature{'extra-branch-refs'}{'default'} =
+	['sandbox', 'wip', 'other'];
+--------------------------------------------------------------------------------
++
+This feature can be configured on per-repository basis after setting
+$feature{'extra-branch-refs'}{'override'} to true, via repository's
+`gitweb.extraBranchRefs` configuration variable, which contains a
+space separated list of refs. An example:
++
+--------------------------------------------------------------------------------
+[gitweb]
+	extraBranchRefs = sandbox wip other
+--------------------------------------------------------------------------------
++
+The gitweb.extraBranchRefs is actually a multi-valued configuration
+variable, so following example is also correct and the result is the
+same as of the snippet above:
++
+--------------------------------------------------------------------------------
+[gitweb]
+	extraBranchRefs = sandbox
+	extraBranchRefs = wip other
+--------------------------------------------------------------------------------
++
+It is an error to specify a ref that does not pass "git check-ref-format"
+scrutiny. Duplicated values are filtered.
+
+
+EXAMPLES
+--------
+
+To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and
+"zip" snapshots), while allowing individual projects to turn them off, put
+the following in your GITWEB_CONFIG file:
+
+	$feature{'blame'}{'default'} = [1];
+	$feature{'blame'}{'override'} = 1;
+
+	$feature{'pickaxe'}{'default'} = [1];
+	$feature{'pickaxe'}{'override'} = 1;
+
+	$feature{'snapshot'}{'default'} = ['zip', 'tgz'];
+	$feature{'snapshot'}{'override'} = 1;
+
+If you allow overriding for the snapshot feature, you can specify which
+snapshot formats are globally disabled. You can also add any command-line
+options you want (such as setting the compression level). For instance, you
+can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by
+adding the following lines to your gitweb configuration file:
+
+	$known_snapshot_formats{'zip'}{'disabled'} = 1;
+	$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
+
+BUGS
+----
+Debugging would be easier if the fallback configuration file
+(`/etc/gitweb.conf`) and environment variable to override its location
+('GITWEB_CONFIG_SYSTEM') had names reflecting their "fallback" role.
+The current names are kept to avoid breaking working setups.
+
+ENVIRONMENT
+-----------
+The location of per-instance and system-wide configuration files can be
+overridden using the following environment variables:
+
+GITWEB_CONFIG::
+	Sets location of per-instance configuration file.
+GITWEB_CONFIG_SYSTEM::
+	Sets location of fallback system-wide configuration file.
+	This file is read only if per-instance one does not exist.
+GITWEB_CONFIG_COMMON::
+	Sets location of common system-wide configuration file.
+
+
+FILES
+-----
+gitweb_config.perl::
+	This is default name of per-instance configuration file.  The
+	format of this file is described above.
+/etc/gitweb.conf::
+	This is default name of fallback system-wide configuration
+	file.  This file is used only if per-instance configuration
+	variable is not found.
+/etc/gitweb-common.conf::
+	This is default name of common system-wide configuration
+	file.

+NAME
+----
+gitweb - Git web interface (web frontend to Git repositories)
+
+SYNOPSIS
+--------
+To get started with gitweb, run linkgit:git-instaweb[1] from a Git repository.
+This would configure and start your web server, and run web browser pointing to
+gitweb.
+
+
+DESCRIPTION
+-----------
+Gitweb provides a web interface to Git repositories.  Its features include:
+
+* Viewing multiple Git repositories with common root.
+* Browsing every revision of the repository.
+* Viewing the contents of files in the repository at any revision.
+* Viewing the revision log of branches, history of files and directories,
+  see what was changed when, by who.
+* Viewing the blame/annotation details of any file (if enabled).
+* Generating RSS and Atom feeds of commits, for any branch.
+  The feeds are auto-discoverable in modern web browsers.
+* Viewing everything that was changed in a revision, and step through
+  revisions one at a time, viewing the history of the repository.
+* Finding commits which commit messages matches given search term.
+
+See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb[] or
+http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/[] for gitweb source code,
+browsed using gitweb itself.
+
+
+CONFIGURATION
+-------------
+Various aspects of gitweb's behavior can be controlled through the configuration
+file 'gitweb_config.perl' or '/etc/gitweb.conf'.  See the linkgit:gitweb.conf[5]
+for details.
+
+Repositories
+~~~~~~~~~~~~
+Gitweb can show information from one or more Git repositories.  These
+repositories have to be all on local filesystem, and have to share common
+repository root, i.e. be all under a single parent repository (but see also
+"Advanced web server setup" section, "Webserver configuration with multiple
+projects' root" subsection).
+
+-----------------------------------------------------------------------
+our $projectroot = '/path/to/parent/directory';
+-----------------------------------------------------------------------
+
+The default value for `$projectroot` is '/pub/git'.  You can change it during
+building gitweb via `GITWEB_PROJECTROOT` build configuration variable.
+
+By default all Git repositories under `$projectroot` are visible and available
+to gitweb.  The list of projects is generated by default by scanning the
+`$projectroot` directory for Git repositories (for object databases to be
+more exact; gitweb is not interested in a working area, and is best suited
+to showing "bare" repositories).
+
+The name of the repository in gitweb is the path to its `$GIT_DIR` (its object
+database) relative to `$projectroot`.  Therefore the repository $repo can be
+found at "$projectroot/$repo".
+
+
+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Instead of having gitweb find repositories by scanning filesystem
+starting from $projectroot, you can provide a pre-generated list of
+visible projects by setting `$projects_list` to point to a plain text
+file with a list of projects (with some additional info).
+
+This file uses the following format:
+
+* One record (for project / repository) per line; does not support line
+continuation (newline escaping).
+
+* Leading and trailing whitespace are ignored.
+
+* Whitespace separated fields; any run of whitespace can be used as field
+separator (rules for Perl's "`split(" ", $line)`").
+
+* Fields use modified URI encoding, defined in RFC 3986, section 2.1
+(Percent-Encoding), or rather "Query string encoding" (see
+http://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference
+being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be
+also percent-encoded).
++
+Reserved characters are: "%" (used for encoding), "{plus}" (can be used to
+encode SPACE), all whitespace characters as defined in Perl, including SP,
+TAB and LF, (used to separate fields in a record).
+
+* Currently recognized fields are:
+<repository path>::
+	path to repository GIT_DIR, relative to `$projectroot`
+<repository owner>::
+	displayed as repository owner, preferably full name, or email,
+	or both
+
+You can generate the projects list index file using the project_index action
+(the 'TXT' link on projects list page) directly from gitweb; see also
+"Generating projects list using gitweb" section below.
+
+Example contents:
+-----------------------------------------------------------------------
+foo.git       Joe+R+Hacker+<joe@example.com>
+foo/bar.git   O+W+Ner+<owner@example.org>
+-----------------------------------------------------------------------
+
+
+By default this file controls only which projects are *visible* on projects
+list page (note that entries that do not point to correctly recognized Git
+repositories won't be displayed by gitweb).  Even if a project is not
+visible on projects list page, you can view it nevertheless by hand-crafting
+a gitweb URL.  By setting `$strict_export` configuration variable (see
+linkgit:gitweb.conf[5]) to true value you can allow viewing only of
+repositories also shown on the overview page (i.e. only projects explicitly
+listed in projects list file will be accessible).
+
+
+Generating projects list using gitweb
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We assume that GITWEB_CONFIG has its default Makefile value, namely
+'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file:
+----------------------------------------------------------------------------
+read_config_file("gitweb_config.perl");
+$projects_list = $projectroot;
+----------------------------------------------------------------------------
+
+Then create the following script to get list of project in the format
+suitable for GITWEB_LIST build configuration variable (or
+`$projects_list` variable in gitweb config):
+
+----------------------------------------------------------------------------
+#!/bin/sh
+
+export GITWEB_CONFIG="gitweb_make_index.perl"
+export GATEWAY_INTERFACE="CGI/1.1"
+export HTTP_ACCEPT="*/*"
+export REQUEST_METHOD="GET"
+export QUERY_STRING="a=project_index"
+
+perl -- /var/www/cgi-bin/gitweb.cgi
+----------------------------------------------------------------------------
+
+Run this script and save its output to a file.  This file could then be used
+as projects list file, which means that you can set `$projects_list` to its
+filename.
+
+
+Controlling access to Git repositories
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+By default all Git repositories under `$projectroot` are visible and
+available to gitweb.  You can however configure how gitweb controls access
+to repositories.
+
+* As described in "Projects list file format" section, you can control which
+projects are *visible* by selectively including repositories in projects
+list file, and setting `$projects_list` gitweb configuration variable to
+point to it.  With `$strict_export` set, projects list file can be used to
+control which repositories are *available* as well.
+
+* You can configure gitweb to only list and allow viewing of the explicitly
+exported repositories, via `$export_ok` variable in gitweb config file; see
+linkgit:gitweb.conf[5] manpage.  If it evaluates to true, gitweb shows
+repositories only if this file named by `$export_ok` exists in its object
+database (if directory has the magic file named `$export_ok`).
++
+For example linkgit:git-daemon[1] by default (unless `--export-all` option
+is used) allows pulling only for those repositories that have
+'git-daemon-export-ok' file.  Adding
++
+--------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+--------------------------------------------------------------------------
++
+makes gitweb show and allow access only to those repositories that can be
+fetched from via `git://` protocol.
+
+* Finally, it is possible to specify an arbitrary perl subroutine that will
+be called for each repository to determine if it can be exported.  The
+subroutine receives an absolute path to the project (repository) as its only
+parameter (i.e. "$projectroot/$project").
++
+For example, if you use mod_perl to run the script, and have dumb
+HTTP protocol authentication configured for your repositories, you
+can use the following hook to allow access only if the user is
+authorized to read the files:
++
+--------------------------------------------------------------------------
+$export_auth_hook = sub {
+	use Apache2::SubRequest ();
+	use Apache2::Const -compile => qw(HTTP_OK);
+	my $path = "$_[0]/HEAD";
+	my $r    = Apache2::RequestUtil->request;
+	my $sub  = $r->lookup_file($path);
+	return $sub->filename eq $path
+	    && $sub->status == Apache2::Const::HTTP_OK;
+};
+--------------------------------------------------------------------------
+
+
+Per-repository gitweb configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can configure individual repositories shown in gitweb by creating file
+in the 'GIT_DIR' of Git repository, or by setting some repo configuration
+variable (in 'GIT_DIR/config', see linkgit:git-config[1]).
+
+You can use the following files in repository:
+
+README.html::
+	A html file (HTML fragment) which is included on the gitweb project
+	"summary" page inside `<div>` block element. You can use it for longer
+	description of a project, to provide links (for example to project's
+	homepage), etc. This is recognized only if XSS prevention is off
+	(`$prevent_xss` is false, see linkgit:gitweb.conf[5]); a way to include
+	a README safely when XSS prevention is on may be worked out in the
+	future.
+
+description (or `gitweb.description`)::
+	Short (shortened to `$projects_list_description_width` in the projects
+	list page, which is 25 characters by default; see
+	linkgit:gitweb.conf[5]) single line description of a project (of a
+	repository).  Plain text file; HTML will be escaped.  By default set to
++
+-------------------------------------------------------------------------------
+Unnamed repository; edit this file to name it for gitweb.
+-------------------------------------------------------------------------------
++
+from the template during repository creation, usually installed in
+'/usr/share/git-core/templates/'.  You can use the `gitweb.description` repo
+configuration variable, but the file takes precedence.
+
+category (or `gitweb.category`)::
+	Singe line category of a project, used to group projects if
+	`$projects_list_group_categories` is enabled.  By default (file and
+	configuration variable absent), uncategorized projects are put in the
+	`$project_list_default_category` category.  You can use the
+	`gitweb.category` repo configuration variable, but the file takes
+	precedence.
++
+The configuration variables `$projects_list_group_categories` and
+`$project_list_default_category` are described in linkgit:gitweb.conf[5]
+
+cloneurl (or multiple-valued `gitweb.url`)::
+	File with repository URL (used for clone and fetch), one per line.
+	Displayed in the project summary page. You can use multiple-valued
+	`gitweb.url` repository configuration variable for that, but the file
+	takes precedence.
++
+This is per-repository enhancement / version of global prefix-based
+`@git_base_url_list` gitweb configuration variable (see
+linkgit:gitweb.conf[5]).
+
+gitweb.owner::
+	You can use the `gitweb.owner` repository configuration variable to set
+	repository's owner.  It is displayed in the project list and summary
+	page.
++
+If it's not set, filesystem directory's owner is used (via GECOS field,
+i.e. real name field from *getpwuid*(3)) if `$projects_list` is unset
+(gitweb scans `$projectroot` for repositories); if `$projects_list`
+points to file with list of repositories, then project owner defaults to
+value from this file for given repository.
+
+various `gitweb.*` config variables (in config)::
+	Read description of `%feature` hash for detailed list, and descriptions.
+	See also "Configuring gitweb features" section in linkgit:gitweb.conf[5]
+
+
+ACTIONS, AND URLS
+-----------------
+Gitweb can use path_info (component) based URLs, or it can pass all necessary
+information via query parameters.  The typical gitweb URLs are broken down in to
+five components:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments>
+-----------------------------------------------------------------------
+
+repo::
+	The repository the action will be performed on.
++
+All actions except for those that list all available projects,
+in whatever form, require this parameter.
+
+action::
+	The action that will be run.  Defaults to 'projects_list' if repo
+	is not set, and to 'summary' otherwise.
+
+revision::
+	Revision shown.  Defaults to HEAD.
+
+path::
+	The path within the <repository> that the action is performed on,
+	for those actions that require it.
+
+arguments::
+	Any arguments that control the behaviour of the action.
+
+Some actions require or allow to specify two revisions, and sometimes even two
+pathnames.  In most general form such path_info (component) based gitweb URL
+looks like this:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments>
+-----------------------------------------------------------------------
+
+
+Each action is implemented as a subroutine, and must be present in %actions
+hash.  Some actions are disabled by default, and must be turned on via feature
+mechanism.  For example to enable 'blame' view add the following to gitweb
+configuration file:
+
+-----------------------------------------------------------------------
+$feature{'blame'}{'default'} = [1];
+-----------------------------------------------------------------------
+
+
+Actions:
+~~~~~~~~
+The standard actions are:
+
+project_list::
+	Lists the available Git repositories.  This is the default command if no
+	repository is specified in the URL.
+
+summary::
+	Displays summary about given repository.  This is the default command if
+	no action is specified in URL, and only repository is specified.
+
+heads::
+remotes::
+	Lists all local or all remote-tracking branches in given repository.
++
+The latter is not available by default, unless configured.
+
+tags::
+	List all tags (lightweight and annotated) in given repository.
+
+blob::
+tree::
+	Shows the files and directories in a given repository path, at given
+	revision.  This is default command if no action is specified in the URL,
+	and path is given.
+
+blob_plain::
+	Returns the raw data for the file in given repository, at given path and
+	revision.  Links to this action are marked 'raw'.
+
+blobdiff::
+	Shows the difference between two revisions of the same file.
+
+blame::
+blame_incremental::
+	Shows the blame (also called annotation) information for a file. On a
+	per line basis it shows the revision in which that line was last changed
+	and the user that committed the change.  The incremental version (which
+	if configured is used automatically when JavaScript is enabled) uses
+	Ajax to incrementally add blame info to the contents of given file.
++
+This action is disabled by default for performance reasons.
+
+commit::
+commitdiff::
+	Shows information about a specific commit in a repository.  The 'commit'
+	view shows information about commit in more detail, the 'commitdiff'
+	action shows changeset for given commit.
+
+patch::
+	Returns the commit in plain text mail format, suitable for applying with
+	linkgit:git-am[1].
+
+tag::
+	Display specific annotated tag (tag object).
+
+log::
+shortlog::
+	Shows log information (commit message or just commit subject) for a
+	given branch (starting from given revision).
++
+The 'shortlog' view is more compact; it shows one commit per line.
+
+history::
+	Shows history of the file or directory in a given repository path,
+	starting from given revision (defaults to HEAD, i.e. default branch).
++
+This view is similar to 'shortlog' view.
+
+rss::
+atom::
+	Generates an RSS (or Atom) feed of changes to repository.
+
+
+WEBSERVER CONFIGURATION
+-----------------------
+This section explains how to configure some common webservers to run gitweb. In
+all cases, `/path/to/gitweb` in the examples is the directory you ran installed
+gitweb in, and contains `gitweb_config.perl`.
+
+If you've configured a web server that isn't listed here for gitweb, please send
+in the instructions so they can be included in a future release.
+
+Apache as CGI
+~~~~~~~~~~~~~
+Apache must be configured to support CGI scripts in the directory in
+which gitweb is installed.  Let's assume that it is '/var/www/cgi-bin'
+directory.
+
+-----------------------------------------------------------------------
+ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
+
+<Directory "/var/www/cgi-bin">
+    Options Indexes FollowSymlinks ExecCGI
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/cgi-bin/gitweb.cgi
+
+Apache with mod_perl, via ModPerl::Registry
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can use mod_perl with gitweb.  You must install Apache::Registry
+(for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable
+this support.
+
+Assuming that gitweb is installed to '/var/www/perl', the following
+Apache configuration (for mod_perl 2.x) is suitable.
+
+-----------------------------------------------------------------------
+Alias /perl "/var/www/perl"
+
+<Directory "/var/www/perl">
+    SetHandler perl-script
+    PerlResponseHandler ModPerl::Registry
+    PerlOptions +ParseHeaders
+    Options Indexes FollowSymlinks +ExecCGI
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/perl/gitweb.cgi
+
+Apache with FastCGI
+~~~~~~~~~~~~~~~~~~~
+Gitweb works with Apache and FastCGI.  First you need to rename, copy
+or symlink gitweb.cgi to gitweb.fcgi.  Let's assume that gitweb is
+installed in '/usr/share/gitweb' directory.  The following Apache
+configuration is suitable (UNTESTED!)
+
+-----------------------------------------------------------------------
+FastCgiServer /usr/share/gitweb/gitweb.cgi
+ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi
+
+Alias /gitweb/static /usr/share/gitweb/static
+<Directory /usr/share/gitweb/static>
+    SetHandler default-handler
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/gitweb
+
+
+ADVANCED WEB SERVER SETUP
+-------------------------
+All of those examples use request rewriting, and need `mod_rewrite`
+(or equivalent; examples below are written for Apache).
+
+Single URL for gitweb and for fetching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to have one URL for both gitweb and your `http://`
+repositories, you can configure Apache like this:
+
+-----------------------------------------------------------------------
+<VirtualHost *:80>
+    ServerName    git.example.org
+    DocumentRoot  /pub/git
+    SetEnv        GITWEB_CONFIG   /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on
+
+    # make the front page an internal rewrite to the gitweb script
+    RewriteRule ^/$  /cgi-bin/gitweb.cgi
+
+    # make access for "dumb clients" work
+    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+		/cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
+</VirtualHost>
+-----------------------------------------------------------------------
+
+The above configuration expects your public repositories to live under
+'/pub/git' and will serve them as `http://git.domain.org/dir-under-pub-git`,
+both as clonable Git URL and as browseable gitweb interface.  If you then
+start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all`
+then you can even use the `git://` URL with exactly the same path.
+
+Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the
+named file (i.e. in this example '/etc/gitweb.conf') as a configuration for
+gitweb.  You don't really need it in above example; it is required only if
+your configuration file is in different place than built-in (during
+compiling gitweb) 'gitweb_config.perl' or '/etc/gitweb.conf'.  See
+linkgit:gitweb.conf[5] for details, especially information about precedence
+rules.
+
+If you use the rewrite rules from the example you *might* also need
+something like the following in your gitweb configuration file
+('/etc/gitweb.conf' following example):
+----------------------------------------------------------------------------
+@stylesheets = ("/some/absolute/path/gitweb.css");
+$my_uri    = "/";
+$home_link = "/";
+$per_request_config = 1;
+----------------------------------------------------------------------------
+Nowadays though gitweb should create HTML base tag when needed (to set base
+URI for relative links), so it should work automatically.
+
+
+Webserver configuration with multiple projects' root
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to use gitweb with several project roots you can edit your
+Apache virtual host and gitweb configuration files in the following way.
+
+The virtual host configuration (in Apache configuration file) should look
+like this:
+--------------------------------------------------------------------------
+<VirtualHost *:80>
+    ServerName    git.example.org
+    DocumentRoot  /pub/git
+    SetEnv        GITWEB_CONFIG  /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on
+
+    # make the front page an internal rewrite to the gitweb script
+    RewriteRule ^/$  /cgi-bin/gitweb.cgi  [QSA,L,PT]
+
+    # look for a public_git folder in unix users' home
+    # http://git.example.org/~<user>/
+    RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # http://git.example.org/+<user>/
+    #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		 [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # http://git.example.org/user/<user>/
+    #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		 [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]

+--------------------------------------------------------------------------
+
+Here actual project root is passed to gitweb via `GITWEB_PROJECT_ROOT`
+environment variable from a web server, so you need to put the following
+line in gitweb configuration file ('/etc/gitweb.conf' in above example):
+--------------------------------------------------------------------------
+$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
+--------------------------------------------------------------------------
+*Note* that this requires to be set for each request, so either
+`$per_request_config` must be false, or the above must be put in code
+referenced by `$per_request_config`;
+
+These configurations enable two things. First, each unix user (`<user>`) of
+the server will be able to browse through gitweb Git repositories found in
+'~/public_git/' with the following url:
+
+  http://git.example.org/~<user>/
+
+If you do not want this feature on your server just remove the second
+rewrite rule.
+
+If you already use `mod_userdir` in your virtual host or you don't want to
+use the \'~' as first character, just comment or remove the second rewrite
+rule, and uncomment one of the following according to what you want.
+
+Second, repositories found in '/pub/scm/' and '/var/git/' will be accessible
+through `http://git.example.org/scm/` and `http://git.example.org/var/`.
+You can add as many project roots as you want by adding rewrite rules like
+the third and the fourth.
+
+
+PATH_INFO usage
+~~~~~~~~~~~~~~~
+If you enable PATH_INFO usage in gitweb by putting
+----------------------------------------------------------------------------
+$feature{'pathinfo'}{'default'} = [1];
+----------------------------------------------------------------------------
+in your gitweb configuration file, it is possible to set up your server so
+that it consumes and produces URLs in the form
+
+  http://git.example.com/project.git/shortlog/sometag
+
+i.e. without 'gitweb.cgi' part, by using a configuration such as the
+following.  This configuration assumes that '/var/www/gitweb' is the
+DocumentRoot of your webserver, contains the gitweb.cgi script and
+complementary static files (stylesheet, favicon, JavaScript):
+
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+	ServerAlias git.example.com
+
+	DocumentRoot /var/www/gitweb
+
+	<Directory /var/www/gitweb>
+		Options ExecCGI
+		AddHandler cgi-script cgi
+
+		DirectoryIndex gitweb.cgi
+
+		RewriteEngine On
+		RewriteCond %{REQUEST_FILENAME} !-f
+		RewriteCond %{REQUEST_FILENAME} !-d
+		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+	</Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+The rewrite rule guarantees that existing static files will be properly
+served, whereas any other URL will be passed to gitweb as PATH_INFO
+parameter.
+
+*Notice* that in this case you don't need special settings for
+`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client"
+access to your project .git dirs (described in "Single URL for gitweb and
+for fetching" section).  A possible workaround for the latter is the
+following: in your project root dir (e.g. '/pub/git') have the projects
+named *without* a .git extension (e.g. '/pub/git/project' instead of
+'/pub/git/project.git') and configure Apache as follows:
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+	ServerAlias git.example.com
+
+	DocumentRoot /var/www/gitweb
+
+	AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
+	<Directory /var/www/gitweb>
+		Options ExecCGI
+		AddHandler cgi-script cgi
+
+		DirectoryIndex gitweb.cgi
+
+		RewriteEngine On
+		RewriteCond %{REQUEST_FILENAME} !-f
+		RewriteCond %{REQUEST_FILENAME} !-d
+		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+	</Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+
+The additional AliasMatch makes it so that
+
+  http://git.example.com/project.git
+
+will give raw access to the project's Git dir (so that the project can be
+cloned), while
+
+  http://git.example.com/project
+
+will provide human-friendly gitweb access.
+
+This solution is not 100% bulletproof, in the sense that if some project has
+a named ref (branch, tag) starting with 'git/', then paths such as
+
+  http://git.example.com/project/command/abranch..git/abranch
+
+will fail with a 404 error.

+===============
+
+NAME
+----
+gitworkflows - An overview of recommended workflows with Git
+
+SYNOPSIS
+--------
+[verse]
+git *
+
+
+DESCRIPTION
+-----------
+
+This document attempts to write down and motivate some of the workflow
+elements used for `git.git` itself.  Many ideas apply in general,
+though the full workflow is rarely required for smaller projects with
+fewer people involved.
+
+We formulate a set of 'rules' for quick reference, while the prose
+tries to motivate each of them.  Do not always take them literally;
+you should value good reasons for your actions higher than manpages
+such as this one.
+
+
+SEPARATE CHANGES
+----------------
+
+As a general rule, you should try to split your changes into small
+logical steps, and commit each of them.  They should be consistent,
+working independently of any later commits, pass the test suite, etc.
+This makes the review process much easier, and the history much more
+useful for later inspection and analysis, for example with
+linkgit:git-blame[1] and linkgit:git-bisect[1].
+
+To achieve this, try to split your work into small steps from the very
+beginning. It is always easier to squash a few commits together than
+to split one big commit into several.  Don't be afraid of making too
+small or imperfect steps along the way. You can always go back later
+and edit the commits with `git rebase --interactive` before you
+publish them.  You can use `git stash save --keep-index` to run the
+test suite independent of other uncommitted changes; see the EXAMPLES
+section of linkgit:git-stash[1].
+
+
+MANAGING BRANCHES
+-----------------
+
+There are two main tools that can be used to include changes from one
+branch on another: linkgit:git-merge[1] and
+linkgit:git-cherry-pick[1].
+
+Merges have many advantages, so we try to solve as many problems as
+possible with merges alone.  Cherry-picking is still occasionally
+useful; see "Merging upwards" below for an example.
+
+Most importantly, merging works at the branch level, while
+cherry-picking works at the commit level.  This means that a merge can
+carry over the changes from 1, 10, or 1000 commits with equal ease,
+which in turn means the workflow scales much better to a large number
+of contributors (and contributions).  Merges are also easier to
+understand because a merge commit is a "promise" that all changes from
+all its parents are now included.
+
+There is a tradeoff of course: merges require a more careful branch
+management.  The following subsections discuss the important points.
+
+
+Graduation
+~~~~~~~~~~
+
+As a given feature goes from experimental to stable, it also
+"graduates" between the corresponding branches of the software.
+`git.git` uses the following 'integration branches':
+
+* 'maint' tracks the commits that should go into the next "maintenance
+  release", i.e., update of the last released stable version;
+
+* 'master' tracks the commits that should go into the next release;
+
+* 'next' is intended as a testing branch for topics being tested for
+  stability for master.
+
+There is a fourth official branch that is used slightly differently:
+
+* 'pu' (proposed updates) is an integration branch for things that are
+  not quite ready for inclusion yet (see "Integration Branches"
+  below).
+
+Each of the four branches is usually a direct descendant of the one
+above it.
+
+Conceptually, the feature enters at an unstable branch (usually 'next'
+or 'pu'), and "graduates" to 'master' for the next release once it is
+considered stable enough.
+
+
+Merging upwards
+~~~~~~~~~~~~~~~
+
+The "downwards graduation" discussed above cannot be done by actually
+merging downwards, however, since that would merge 'all' changes on
+the unstable branch into the stable one.  Hence the following:
+
+.Merge upwards
+[caption="Rule: "]
+=====================================
+Always commit your fixes to the oldest supported branch that require
+them.  Then (periodically) merge the integration branches upwards into each
+other.
+=====================================
+
+This gives a very controlled flow of fixes.  If you notice that you
+have applied a fix to e.g. 'master' that is also required in 'maint',
+you will need to cherry-pick it (using linkgit:git-cherry-pick[1])
+downwards.  This will happen a few times and is nothing to worry about
+unless you do it very frequently.
+
+
+Topic branches
+~~~~~~~~~~~~~~
+
+Any nontrivial feature will require several patches to implement, and
+may get extra bugfixes or improvements during its lifetime.
+
+Committing everything directly on the integration branches leads to many
+problems: Bad commits cannot be undone, so they must be reverted one
+by one, which creates confusing histories and further error potential
+when you forget to revert part of a group of changes.  Working in
+parallel mixes up the changes, creating further confusion.
+
+Use of "topic branches" solves these problems.  The name is pretty
+self explanatory, with a caveat that comes from the "merge upwards"
+rule above:
+
+.Topic branches
+[caption="Rule: "]
+=====================================
+Make a side branch for every topic (feature, bugfix, ...). Fork it off
+at the oldest integration branch that you will eventually want to merge it
+into.
+=====================================
+
+Many things can then be done very naturally:
+
+* To get the feature/bugfix into an integration branch, simply merge
+  it.  If the topic has evolved further in the meantime, merge again.
+  (Note that you do not necessarily have to merge it to the oldest
+  integration branch first.  For example, you can first merge a bugfix
+  to 'next', give it some testing time, and merge to 'maint' when you
+  know it is stable.)
+
+* If you find you need new features from the branch 'other' to continue
+  working on your topic, merge 'other' to 'topic'.  (However, do not
+  do this "just habitually", see below.)
+
+* If you find you forked off the wrong branch and want to move it
+  "back in time", use linkgit:git-rebase[1].
+
+Note that the last point clashes with the other two: a topic that has
+been merged elsewhere should not be rebased.  See the section on
+RECOVERING FROM UPSTREAM REBASE in linkgit:git-rebase[1].
+
+We should point out that "habitually" (regularly for no real reason)
+merging an integration branch into your topics -- and by extension,
+merging anything upstream into anything downstream on a regular basis
+-- is frowned upon:
+
+.Merge to downstream only at well-defined points
+[caption="Rule: "]
+=====================================
+Do not merge to downstream except with a good reason: upstream API
+changes affect your branch; your branch no longer merges to upstream
+cleanly; etc.
+=====================================
+
+Otherwise, the topic that was merged to suddenly contains more than a
+single (well-separated) change.  The many resulting small merges will
+greatly clutter up history.  Anyone who later investigates the history
+of a file will have to find out whether that merge affected the topic
+in development.  An upstream might even inadvertently be merged into a
+"more stable" branch.  And so on.
+
+
+Throw-away integration
+~~~~~~~~~~~~~~~~~~~~~~
+
+If you followed the last paragraph, you will now have many small topic
+branches, and occasionally wonder how they interact.  Perhaps the
+result of merging them does not even work?  But on the other hand, we
+want to avoid merging them anywhere "stable" because such merges
+cannot easily be undone.
+
+The solution, of course, is to make a merge that we can undo: merge
+into a throw-away branch.
+
+.Throw-away integration branches
+[caption="Rule: "]
+=====================================
+To test the interaction of several topics, merge them into a
+throw-away branch.  You must never base any work on such a branch!
+=====================================
+
+If you make it (very) clear that this branch is going to be deleted
+right after the testing, you can even publish this branch, for example
+to give the testers a chance to work with it, or other developers a
+chance to see if their in-progress work will be compatible.  `git.git`
+has such an official throw-away integration branch called 'pu'.
+
+
+Branch management for a release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Assuming you are using the merge approach discussed above, when you
+are releasing your project you will need to do some additional branch
+management work.
+
+A feature release is created from the 'master' branch, since 'master'
+tracks the commits that should go into the next feature release.
+
+The 'master' branch is supposed to be a superset of 'maint'. If this
+condition does not hold, then 'maint' contains some commits that
+are not included on 'master'. The fixes represented by those commits
+will therefore not be included in your feature release.
+
+To verify that 'master' is indeed a superset of 'maint', use git log:
+
+.Verify 'master' is a superset of 'maint'
+[caption="Recipe: "]
+=====================================
+`git log master..maint`
+=====================================
+
+This command should not list any commits.  Otherwise, check out
+'master' and merge 'maint' into it.
+
+Now you can proceed with the creation of the feature release. Apply a
+tag to the tip of 'master' indicating the release version:
+
+.Release tagging
+[caption="Recipe: "]
+=====================================
+`git tag -s -m "Git X.Y.Z" vX.Y.Z master`
+=====================================
+
+You need to push the new tag to a public Git server (see
+"DISTRIBUTED WORKFLOWS" below). This makes the tag available to
+others tracking your project. The push could also trigger a
+post-update hook to perform release-related items such as building
+release tarballs and preformatted documentation pages.
+
+Similarly, for a maintenance release, 'maint' is tracking the commits
+to be released. Therefore, in the steps above simply tag and push
+'maint' rather than 'master'.
+
+
+Maintenance branch management after a feature release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a feature release, you need to manage your maintenance branches.
+
+First, if you wish to continue to release maintenance fixes for the
+feature release made before the recent one, then you must create
+another branch to track commits for that previous release.
+
+To do this, the current maintenance branch is copied to another branch
+named with the previous release version number (e.g. maint-X.Y.(Z-1)
+where X.Y.Z is the current release).
+
+.Copy maint
+[caption="Recipe: "]
+=====================================
+`git branch maint-X.Y.(Z-1) maint`
+=====================================
+
+The 'maint' branch should now be fast-forwarded to the newly released
+code so that maintenance fixes can be tracked for the current release:
+
+.Update maint to new release
+[caption="Recipe: "]
+=====================================
+* `git checkout maint`
+* `git merge --ff-only master`
+=====================================
+
+If the merge fails because it is not a fast-forward, then it is
+possible some fixes on 'maint' were missed in the feature release.
+This will not happen if the content of the branches was verified as
+described in the previous section.
+
+
+Branch management for next and pu after a feature release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a feature release, the integration branch 'next' may optionally be
+rewound and rebuilt from the tip of 'master' using the surviving
+topics on 'next':
+
+.Rewind and rebuild next
+[caption="Recipe: "]
+=====================================
+* `git checkout next`
+* `git reset --hard master`
+* `git merge ai/topic_in_next1`
+* `git merge ai/topic_in_next2`
+* ...
+=====================================
+
+The advantage of doing this is that the history of 'next' will be
+clean. For example, some topics merged into 'next' may have initially
+looked promising, but were later found to be undesirable or premature.
+In such a case, the topic is reverted out of 'next' but the fact
+remains in the history that it was once merged and reverted. By
+recreating 'next', you give another incarnation of such topics a clean
+slate to retry, and a feature release is a good point in history to do
+so.
+
+If you do this, then you should make a public announcement indicating
+that 'next' was rewound and rebuilt.
+
+The same rewind and rebuild process may be followed for 'pu'. A public
+announcement is not necessary since 'pu' is a throw-away branch, as
+described above.
+
+
+DISTRIBUTED WORKFLOWS
+---------------------
+
+After the last section, you should know how to manage topics.  In
+general, you will not be the only person working on the project, so
+you will have to share your work.
+
+Roughly speaking, there are two important workflows: merge and patch.
+The important difference is that the merge workflow can propagate full
+history, including merges, while patches cannot.  Both workflows can
+be used in parallel: in `git.git`, only subsystem maintainers use
+the merge workflow, while everyone else sends patches.
+
+Note that the maintainer(s) may impose restrictions, such as
+"Signed-off-by" requirements, that all commits/patches submitted for
+inclusion must adhere to.  Consult your project's documentation for
+more information.
+
+
+Merge workflow
+~~~~~~~~~~~~~~
+
+The merge workflow works by copying branches between upstream and
+downstream.  Upstream can merge contributions into the official
+history; downstream base their work on the official history.
+
+There are three main tools that can be used for this:
+
+* linkgit:git-push[1] copies your branches to a remote repository,
+  usually to one that can be read by all involved parties;
+
+* linkgit:git-fetch[1] that copies remote branches to your repository;
+  and
+
+* linkgit:git-pull[1] that does fetch and merge in one go.
+
+Note the last point.  Do 'not' use 'git pull' unless you actually want
+to merge the remote branch.
+
+Getting changes out is easy:
+
+.Push/pull: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+`git push <remote> <branch>` and tell everyone where they can fetch
+from.
+=====================================
+
+You will still have to tell people by other means, such as mail.  (Git
+provides the linkgit:git-request-pull[1] to send preformatted pull
+requests to upstream maintainers to simplify this task.)
+
+If you just want to get the newest copies of the integration branches,
+staying up to date is easy too:
+
+.Push/pull: Staying up to date
+[caption="Recipe: "]
+=====================================
+Use `git fetch <remote>` or `git remote update` to stay up to date.
+=====================================
+
+Then simply fork your topic branches from the stable remotes as
+explained earlier.
+
+If you are a maintainer and would like to merge other people's topic
+branches to the integration branches, they will typically send a
+request to do so by mail.  Such a request looks like
+
+-------------------------------------
+Please pull from
+    <url> <branch>
+-------------------------------------
+
+In that case, 'git pull' can do the fetch and merge in one go, as
+follows.
+
+.Push/pull: Merging remote topics
+[caption="Recipe: "]
+=====================================
+`git pull <url> <branch>`
+=====================================
+
+Occasionally, the maintainer may get merge conflicts when he tries to
+pull changes from downstream.  In this case, he can ask downstream to
+do the merge and resolve the conflicts themselves (perhaps they will
+know better how to resolve them).  It is one of the rare cases where
+downstream 'should' merge from upstream.
+
+
+Patch workflow
+~~~~~~~~~~~~~~
+
+If you are a contributor that sends changes upstream in the form of
+emails, you should use topic branches as usual (see above).  Then use
+linkgit:git-format-patch[1] to generate the corresponding emails
+(highly recommended over manually formatting them because it makes the
+maintainer's life easier).
+
+.format-patch/am: Publishing branches/topics
+[caption="Recipe: "]
+=====================================
+* `git format-patch -M upstream..topic` to turn them into preformatted
+  patch files
+* `git send-email --to=<recipient> <patches>`
+=====================================
+
+See the linkgit:git-format-patch[1] and linkgit:git-send-email[1]
+manpages for further usage notes.
+
+If the maintainer tells you that your patch no longer applies to the
+current upstream, you will have to rebase your topic (you cannot use a
+merge because you cannot format-patch merges):
+
+.format-patch/am: Keeping topics up to date
+[caption="Recipe: "]
+=====================================
+`git pull --rebase <url> <branch>`
+=====================================
+
+You can then fix the conflicts during the rebase.  Presumably you have
+not published your topic other than by mail, so rebasing it is not a
+problem.
+
+If you receive such a patch series (as maintainer, or perhaps as a
+reader of the mailing list it was sent to), save the mails to files,
+create a new topic branch and use 'git am' to import the commits:
+
+.format-patch/am: Importing patches
+[caption="Recipe: "]
+=====================================
+`git am < patch`
+=====================================
+
+One feature worth pointing out is the three-way merge, which can help
+if you get conflicts: `git am -3` will use index information contained
+in patches to figure out the merge base.  See linkgit:git-am[1] for
+other options.

+	to the top <<def_directory,directory>> of the stored
+	revision.
+
+[[def_commit-ish]]commit-ish (also committish)::
+	A <<def_commit_object,commit object>> or an
+	<<def_object,object>> that can be recursively dereferenced to
+	a commit object.
+	The following are all commit-ishes:
+	a commit object,
+	a <<def_tag_object,tag object>> that points to a commit
+	object,
+	a tag object that points to a tag object that points to a
+	commit object,
+	etc.
+
+[[def_core_git]]core Git::
+	Fundamental data structures and utilities of Git. Exposes only limited
+	source code management tools.
+
+[[def_DAG]]DAG::
+	Directed acyclic graph. The <<def_commit_object,commit objects>> form a
+	directed acyclic graph, because they have parents (directed), and the
+	graph of commit objects is acyclic (there is no <<def_chain,chain>>
+	which begins and ends with the same <<def_object,object>>).
+
+[[def_dangling_object]]dangling object::
+	An <<def_unreachable_object,unreachable object>> which is not
+	<<def_reachable,reachable>> even from other unreachable objects; a
+	dangling object has no references to it from any
+	reference or <<def_object,object>> in the <<def_repository,repository>>.
+
+[[def_detached_HEAD]]detached HEAD::
+	Normally the <<def_HEAD,HEAD>> stores the name of a
+	<<def_branch,branch>>, and commands that operate on the
+	history HEAD represents operate on the history leading to the
+	tip of the branch the HEAD points at.  However, Git also
+	allows you to <<def_checkout,check out>> an arbitrary
+	<<def_commit,commit>> that isn't necessarily the tip of any
+	particular branch.  The HEAD in such a state is called
+	"detached".
++
+Note that commands that operate on the history of the current branch
+(e.g. `git commit` to build a new history on top of it) still work
+while the HEAD is detached. They update the HEAD to point at the tip
+of the updated history without affecting any branch.  Commands that
+update or inquire information _about_ the current branch (e.g. `git
+branch --set-upstream-to` that sets what remote-tracking branch the
+current branch integrates with) obviously do not work, as there is no
+(real) current branch to ask about in this state.
+
+[[def_directory]]directory::
+	The list you get with "ls" :-)
+
+[[def_dirty]]dirty::
+	A <<def_working_tree,working tree>> is said to be "dirty" if
+	it contains modifications which have not been <<def_commit,committed>> to the current
+	<<def_branch,branch>>.
+
+[[def_evil_merge]]evil merge::
+	An evil merge is a <<def_merge,merge>> that introduces changes that
+	do not appear in any <<def_parent,parent>>.
+
+[[def_fast_forward]]fast-forward::
+	A fast-forward is a special type of <<def_merge,merge>> where you have a
+	<<def_revision,revision>> and you are "merging" another
+	<<def_branch,branch>>'s changes that happen to be a descendant of what
+	you have. In such these cases, you do not make a new <<def_merge,merge>>
+	<<def_commit,commit>> but instead just update to his
+	revision. This will happen frequently on a
+	<<def_remote_tracking_branch,remote-tracking branch>> of a remote
+	<<def_repository,repository>>.
+
+[[def_fetch]]fetch::
+	Fetching a <<def_branch,branch>> means to get the
+	branch's <<def_head_ref,head ref>> from a remote
+	<<def_repository,repository>>, to find out which objects are
+	missing from the local <<def_object_database,object database>>,
+	and to get them, too.  See also linkgit:git-fetch[1].
+
+[[def_file_system]]file system::
+	Linus Torvalds originally designed Git to be a user space file system,
+	i.e. the infrastructure to hold files and directories. That ensured the
+	efficiency and speed of Git.
+
+[[def_git_archive]]Git archive::
+	Synonym for <<def_repository,repository>> (for arch people).
+
+[[def_gitfile]]gitfile::
+	A plain file `.git` at the root of a working tree that
+	points at the directory that is the real repository.
+
+[[def_grafts]]grafts::
+	Grafts enables two otherwise different lines of development to be joined
+	together by recording fake ancestry information for commits. This way
+	you can make Git pretend the set of <<def_parent,parents>> a <<def_commit,commit>> has
+	is different from what was recorded when the commit was
+	created. Configured via the `.git/info/grafts` file.
++
+Note that the grafts mechanism is outdated and can lead to problems
+transferring objects between repositories; see linkgit:git-replace[1]
+for a more flexible and robust system to do the same thing.
+
+[[def_hash]]hash::
+	In Git's context, synonym for <<def_object_name,object name>>.
+
+[[def_head]]head::
+	A <<def_ref,named reference>> to the <<def_commit,commit>> at the tip of a
+	<<def_branch,branch>>.  Heads are stored in a file in
+	`$GIT_DIR/refs/heads/` directory, except when using packed refs. (See
+	linkgit:git-pack-refs[1].)
+
+[[def_HEAD]]HEAD::
+	The current <<def_branch,branch>>.  In more detail: Your <<def_working_tree,
+	working tree>> is normally derived from the state of the tree
+	referred to by HEAD.  HEAD is a reference to one of the
+	<<def_head,heads>> in your repository, except when using a
+	<<def_detached_HEAD,detached HEAD>>, in which case it directly
+	references an arbitrary commit.
+
+[[def_head_ref]]head ref::
+	A synonym for <<def_head,head>>.
+
+[[def_hook]]hook::
+	During the normal execution of several Git commands, call-outs are made
+	to optional scripts that allow a developer to add functionality or
+	checking. Typically, the hooks allow for a command to be pre-verified
+	and potentially aborted, and allow for a post-notification after the
+	operation is done. The hook scripts are found in the
+	`$GIT_DIR/hooks/` directory, and are enabled by simply
+	removing the `.sample` suffix from the filename. In earlier versions
+	of Git you had to make them executable.
+
+[[def_index]]index::
+	A collection of files with stat information, whose contents are stored
+	as objects. The index is a stored version of your
+	<<def_working_tree,working tree>>. Truth be told, it can also contain a second, and even
+	a third version of a working tree, which are used
+	when <<def_merge,merging>>.
+
+[[def_index_entry]]index entry::
+	The information regarding a particular file, stored in the
+	<<def_index,index>>. An index entry can be unmerged, if a
+	<<def_merge,merge>> was started, but not yet finished (i.e. if
+	the index contains multiple versions of that file).
+
+[[def_master]]master::
+	The default development <<def_branch,branch>>. Whenever you
+	create a Git <<def_repository,repository>>, a branch named
+	"master" is created, and becomes the active branch. In most
+	cases, this contains the local development, though that is
+	purely by convention and is not required.
+
+[[def_merge]]merge::
+	As a verb: To bring the contents of another
+	<<def_branch,branch>> (possibly from an external
+	<<def_repository,repository>>) into the current branch.  In the
+	case where the merged-in branch is from a different repository,
+	this is done by first <<def_fetch,fetching>> the remote branch
+	and then merging the result into the current branch.  This
+	combination of fetch and merge operations is called a
+	<<def_pull,pull>>.  Merging is performed by an automatic process
+	that identifies changes made since the branches diverged, and
+	then applies all those changes together.  In cases where changes
+	conflict, manual intervention may be required to complete the
+	merge.
++
+As a noun: unless it is a <<def_fast_forward,fast-forward>>, a
+successful merge results in the creation of a new <<def_commit,commit>>
+representing the result of the merge, and having as
+<<def_parent,parents>> the tips of the merged <<def_branch,branches>>.
+This commit is referred to as a "merge commit", or sometimes just a
+"merge".
+
+[[def_object]]object::
+	The unit of storage in Git. It is uniquely identified by the
+	<<def_SHA1,SHA-1>> of its contents. Consequently, an
+	object can not be changed.
+
+[[def_object_database]]object database::
+	Stores a set of "objects", and an individual <<def_object,object>> is
+	identified by its <<def_object_name,object name>>. The objects usually
+	live in `$GIT_DIR/objects/`.
+
+[[def_object_identifier]]object identifier::
+	Synonym for <<def_object_name,object name>>.
+
+[[def_object_name]]object name::
+	The unique identifier of an <<def_object,object>>.  The
+	object name is usually represented by a 40 character
+	hexadecimal string.  Also colloquially called <<def_SHA1,SHA-1>>.
+
+[[def_object_type]]object type::
+	One of the identifiers "<<def_commit_object,commit>>",
+	"<<def_tree_object,tree>>", "<<def_tag_object,tag>>" or
+	"<<def_blob_object,blob>>" describing the type of an
+	<<def_object,object>>.
+
+[[def_octopus]]octopus::
+	To <<def_merge,merge>> more than two <<def_branch,branches>>.
+
+[[def_origin]]origin::
+	The default upstream <<def_repository,repository>>. Most projects have
+	at least one upstream project which they track. By default
+	'origin' is used for that purpose. New upstream updates
+	will be fetched into <<def_remote_tracking_branch,remote-tracking branches>> named
+	origin/name-of-upstream-branch, which you can see using
+	`git branch -r`.
+
+[[def_pack]]pack::
+	A set of objects which have been compressed into one file (to save space
+	or to transmit them efficiently).
+
+[[def_pack_index]]pack index::
+	The list of identifiers, and other information, of the objects in a
+	<<def_pack,pack>>, to assist in efficiently accessing the contents of a
+	pack.
+
+[[def_pathspec]]pathspec::
+	Pattern used to limit paths in Git commands.
++
+Pathspecs are used on the command line of "git ls-files", "git
+ls-tree", "git add", "git grep", "git diff", "git checkout",
+and many other commands to
+limit the scope of operations to some subset of the tree or
+worktree.  See the documentation of each command for whether
+paths are relative to the current directory or toplevel.  The
+pathspec syntax is as follows:
++
+--
+
+* any path matches itself
+* the pathspec up to the last slash represents a
+  directory prefix.  The scope of that pathspec is
+  limited to that subtree.
+* the rest of the pathspec is a pattern for the remainder
+  of the pathname.  Paths relative to the directory
+  prefix will be matched against that pattern using fnmatch(3);
+  in particular, '*' and '?' _can_ match directory separators.
+
+--
++
+For example, Documentation/*.jpg will match all .jpg files
+in the Documentation subtree,
+including Documentation/chapter_1/figure_1.jpg.
++
+A pathspec that begins with a colon `:` has special meaning.  In the
+short form, the leading colon `:` is followed by zero or more "magic
+signature" letters (which optionally is terminated by another colon `:`),
+and the remainder is the pattern to match against the path.
+The "magic signature" consists of ASCII symbols that are neither
+alphanumeric, glob, regex special characters nor colon.
+The optional colon that terminates the "magic signature" can be
+omitted if the pattern begins with a character that does not belong to
+"magic signature" symbol set and is not a colon.
++
+In the long form, the leading colon `:` is followed by a open
+parenthesis `(`, a comma-separated list of zero or more "magic words",
+and a close parentheses `)`, and the remainder is the pattern to match
+against the path.
++
+A pathspec with only a colon means "there is no pathspec". This form
+should not be combined with other pathspec.
++
+--
+top;;
+	The magic word `top` (magic signature: `/`) makes the pattern
+	match from the root of the working tree, even when you are
+	running the command from inside a subdirectory.
+
+literal;;
+	Wildcards in the pattern such as `*` or `?` are treated
+	as literal characters.
+
+icase;;
+	Case insensitive match.
+
+glob;;
+	Git treats the pattern as a shell glob suitable for
+	consumption by fnmatch(3) with the FNM_PATHNAME flag:
+	wildcards in the pattern will not match a / in the pathname.
+	For example, "Documentation/{asterisk}.html" matches
+	"Documentation/git.html" but not "Documentation/ppc/ppc.html"
+	or "tools/perf/Documentation/perf.html".
++
+Two consecutive asterisks ("`**`") in patterns matched against
+full pathname may have special meaning:
+
+ - A leading "`**`" followed by a slash means match in all
+   directories. For example, "`**/foo`" matches file or directory
+   "`foo`" anywhere, the same as pattern "`foo`". "`**/foo/bar`"
+   matches file or directory "`bar`" anywhere that is directly
+   under directory "`foo`".
+
+ - A trailing "`/**`" matches everything inside. For example,
+   "`abc/**`" matches all files inside directory "abc", relative
+   to the location of the `.gitignore` file, with infinite depth.
+
+ - A slash followed by two consecutive asterisks then a slash
+   matches zero or more directories. For example, "`a/**/b`"
+   matches "`a/b`", "`a/x/b`", "`a/x/y/b`" and so on.
+
+ - Other consecutive asterisks are considered invalid.
++
+Glob magic is incompatible with literal magic.
+
+exclude;;
+	After a path matches any non-exclude pathspec, it will be run
+	through all exclude pathspec (magic signature: `!`). If it
+	matches, the path is ignored.
+--
+
+[[def_parent]]parent::
+	A <<def_commit_object,commit object>> contains a (possibly empty) list
+	of the logical predecessor(s) in the line of development, i.e. its
+	parents.
+
+[[def_pickaxe]]pickaxe::
+	The term <<def_pickaxe,pickaxe>> refers to an option to the diffcore
+	routines that help select changes that add or delete a given text
+	string. With the `--pickaxe-all` option, it can be used to view the full
+	<<def_changeset,changeset>> that introduced or removed, say, a
+	particular line of text. See linkgit:git-diff[1].
+
+[[def_plumbing]]plumbing::
+	Cute name for <<def_core_git,core Git>>.
+
+[[def_porcelain]]porcelain::
+	Cute name for programs and program suites depending on
+	<<def_core_git,core Git>>, presenting a high level access to
+	core Git. Porcelains expose more of a <<def_SCM,SCM>>
+	interface than the <<def_plumbing,plumbing>>.
+
+[[def_per_worktree_ref]]per-worktree ref::
+	Refs that are per-<<def_working_tree,worktree>>, rather than
+	global.  This is presently only <<def_HEAD,HEAD>>, but might
+	later include other unusual refs.
+
+[[def_pseudoref]]pseudoref::
+	Pseudorefs are a class of files under `$GIT_DIR` which behave
+	like refs for the purposes of rev-parse, but which are treated
+	specially by git.  Pseudorefs both have names that are all-caps,
+	and always start with a line consisting of a
+	<<def_SHA1,SHA-1>> followed by whitespace.  So, HEAD is not a
+	pseudoref, because it is sometimes a symbolic ref.  They might
+	optionally contain some additional data.  `MERGE_HEAD` and
+	`CHERRY_PICK_HEAD` are examples.  Unlike
+	<<def_per_worktree_ref,per-worktree refs>>, these files cannot
+	be symbolic refs, and never have reflogs.  They also cannot be
+	updated through the normal ref update machinery.  Instead,
+	they are updated by directly writing to the files.  However,
+	they can be read as if they were refs, so `git rev-parse
+	MERGE_HEAD` will work.
+
+[[def_pull]]pull::
+	Pulling a <<def_branch,branch>> means to <<def_fetch,fetch>> it and
+	<<def_merge,merge>> it.  See also linkgit:git-pull[1].
+
+[[def_push]]push::
+	Pushing a <<def_branch,branch>> means to get the branch's
+	<<def_head_ref,head ref>> from a remote <<def_repository,repository>>,
+	find out if it is a direct ancestor to the branch's local
+	head ref, and in that case, putting all
+	objects, which are <<def_reachable,reachable>> from the local
+	head ref, and which are missing from the remote
+	repository, into the remote
+	<<def_object_database,object database>>, and updating the remote
+	head ref. If the remote <<def_head,head>> is not an
+	ancestor to the local head, the push fails.
+
+[[def_reachable]]reachable::
+	All of the ancestors of a given <<def_commit,commit>> are said to be
+	"reachable" from that commit. More
+	generally, one <<def_object,object>> is reachable from
+	another if we can reach the one from the other by a <<def_chain,chain>>
+	that follows <<def_tag,tags>> to whatever they tag,
+	<<def_commit_object,commits>> to their parents or trees, and
+	<<def_tree_object,trees>> to the trees or <<def_blob_object,blobs>>
+	that they contain.
+
+[[def_rebase]]rebase::
+	To reapply a series of changes from a <<def_branch,branch>> to a
+	different base, and reset the <<def_head,head>> of that branch
+	to the result.
+
+[[def_ref]]ref::
+	A name that begins with `refs/` (e.g. `refs/heads/master`)
+	that points to an <<def_object_name,object name>> or another
+	ref (the latter is called a <<def_symref,symbolic ref>>).
+	For convenience, a ref can sometimes be abbreviated when used
+	as an argument to a Git command; see linkgit:gitrevisions[7]
+	for details.
+	Refs are stored in the <<def_repository,repository>>.
++
+The ref namespace is hierarchical.
+Different subhierarchies are used for different purposes (e.g. the
+`refs/heads/` hierarchy is used to represent local branches).
++
+There are a few special-purpose refs that do not begin with `refs/`.
+The most notable example is `HEAD`.
+
+[[def_reflog]]reflog::
+	A reflog shows the local "history" of a ref.  In other words,
+	it can tell you what the 3rd last revision in _this_ repository
+	was, and what was the current state in _this_ repository,
+	yesterday 9:14pm.  See linkgit:git-reflog[1] for details.
+
+[[def_refspec]]refspec::
+	A "refspec" is used by <<def_fetch,fetch>> and
+	<<def_push,push>> to describe the mapping between remote
+	<<def_ref,ref>> and local ref.
+
+[[def_remote]]remote repository::
+	A <<def_repository,repository>> which is used to track the same
+	project but resides somewhere else. To communicate with remotes,
+	see <<def_fetch,fetch>> or <<def_push,push>>.
+
+[[def_remote_tracking_branch]]remote-tracking branch::
+	A <<def_ref,ref>> that is used to follow changes from another
+	<<def_repository,repository>>. It typically looks like
+	'refs/remotes/foo/bar' (indicating that it tracks a branch named
+	'bar' in a remote named 'foo'), and matches the right-hand-side of
+	a configured fetch <<def_refspec,refspec>>. A remote-tracking
+	branch should not contain direct modifications or have local
+	commits made to it.
+
+[[def_repository]]repository::
+	A collection of <<def_ref,refs>> together with an
+	<<def_object_database,object database>> containing all objects
+	which are <<def_reachable,reachable>> from the refs, possibly
+	accompanied by meta data from one or more <<def_porcelain,porcelains>>. A
+	repository can share an object database with other repositories
+	via <<def_alternate_object_database,alternates mechanism>>.
+
+[[def_resolve]]resolve::
+	The action of fixing up manually what a failed automatic
+	<<def_merge,merge>> left behind.
+
+[[def_revision]]revision::
+	Synonym for <<def_commit,commit>> (the noun).
+
+[[def_rewind]]rewind::
+	To throw away part of the development, i.e. to assign the
+	<<def_head,head>> to an earlier <<def_revision,revision>>.
+
+[[def_SCM]]SCM::
+	Source code management (tool).
+
+[[def_SHA1]]SHA-1::
+	"Secure Hash Algorithm 1"; a cryptographic hash function.
+	In the context of Git used as a synonym for <<def_object_name,object name>>.
+
+[[def_shallow_repository]]shallow repository::
+	A shallow <<def_repository,repository>> has an incomplete
+	history some of whose <<def_commit,commits>> have <<def_parent,parents>> cauterized away (in other
+	words, Git is told to pretend that these commits do not have the
+	parents, even though they are recorded in the <<def_commit_object,commit
+	object>>). This is sometimes useful when you are interested only in the
+	recent history of a project even though the real history recorded in the
+	upstream is much larger. A shallow repository
+	is created by giving the `--depth` option to linkgit:git-clone[1], and
+	its history can be later deepened with linkgit:git-fetch[1].
+
+[[def_submodule]]submodule::
+	A <<def_repository,repository>> that holds the history of a
+	separate project inside another repository (the latter of
+	which is called <<def_superproject, superproject>>).
+
+[[def_superproject]]superproject::
+	A <<def_repository,repository>> that references repositories
+	of other projects in its working tree as <<def_submodule,submodules>>.
+	The superproject knows about the names of (but does not hold
+	copies of) commit objects of the contained submodules.
+
+[[def_symref]]symref::
+	Symbolic reference: instead of containing the <<def_SHA1,SHA-1>>
+	id itself, it is of the format 'ref: refs/some/thing' and when
+	referenced, it recursively dereferences to this reference.
+	'<<def_HEAD,HEAD>>' is a prime example of a symref. Symbolic
+	references are manipulated with the linkgit:git-symbolic-ref[1]
+	command.
+
+[[def_tag]]tag::
+	A <<def_ref,ref>> under `refs/tags/` namespace that points to an
+	object of an arbitrary type (typically a tag points to either a
+	<<def_tag_object,tag>> or a <<def_commit_object,commit object>>).
+	In contrast to a <<def_head,head>>, a tag is not updated by
+	the `commit` command. A Git tag has nothing to do with a Lisp
+	tag (which would be called an <<def_object_type,object type>>
+	in Git's context). A tag is most typically used to mark a particular
+	point in the commit ancestry <<def_chain,chain>>.
+
+[[def_tag_object]]tag object::
+	An <<def_object,object>> containing a <<def_ref,ref>> pointing to
+	another object, which can contain a message just like a
+	<<def_commit_object,commit object>>. It can also contain a (PGP)
+	signature, in which case it is called a "signed tag object".
+
+[[def_topic_branch]]topic branch::
+	A regular Git <<def_branch,branch>> that is used by a developer to
+	identify a conceptual line of development. Since branches are very easy
+	and inexpensive, it is often desirable to have several small branches
+	that each contain very well defined concepts or small incremental yet
+	related changes.
+
+[[def_tree]]tree::
+	Either a <<def_working_tree,working tree>>, or a <<def_tree_object,tree
+	object>> together with the dependent <<def_blob_object,blob>> and tree objects
+	(i.e. a stored representation of a working tree).
+
+[[def_tree_object]]tree object::
+	An <<def_object,object>> containing a list of file names and modes along
+	with refs to the associated blob and/or tree objects. A
+	<<def_tree,tree>> is equivalent to a <<def_directory,directory>>.
+
+[[def_tree-ish]]tree-ish (also treeish)::
+	A <<def_tree_object,tree object>> or an <<def_object,object>>
+	that can be recursively dereferenced to a tree object.
+	Dereferencing a <<def_commit_object,commit object>> yields the
+	tree object corresponding to the <<def_revision,revision>>'s
+	top <<def_directory,directory>>.
+	The following are all tree-ishes:
+	a <<def_commit-ish,commit-ish>>,
+	a tree object,
+	a <<def_tag_object,tag object>> that points to a tree object,
+	a tag object that points to a tag object that points to a tree
+	object,
+	etc.
+
+[[def_unmerged_index]]unmerged index::
+	An <<def_index,index>> which contains unmerged
+	<<def_index_entry,index entries>>.
+
+[[def_unreachable_object]]unreachable object::
+	An <<def_object,object>> which is not <<def_reachable,reachable>> from a
+	<<def_branch,branch>>, <<def_tag,tag>>, or any other reference.
+
+[[def_upstream_branch]]upstream branch::
+	The default <<def_branch,branch>> that is merged into the branch in
+	question (or the branch in question is rebased onto). It is configured
+	via branch.<name>.remote and branch.<name>.merge. If the upstream branch
+	of 'A' is 'origin/B' sometimes we say "'A' is tracking 'origin/B'".
+
+[[def_working_tree]]working tree::
+	The tree of actual checked out files.  The working tree normally
+	contains the contents of the <<def_HEAD,HEAD>> commit's tree,
+	plus any local changes that you have made but not yet committed.

-
-bare repository::
-	A bare repository is normally an appropriately named
-	directory with a `.git` suffix that does not have a

-	control.  That is, all of the `git` administrative and
-	control files that would normally be present in the

-
-branch::
-	A non-cyclical graph of revisions, i.e. the complete history of

-	the term "changesets" with git.
-
-checkout::
-	The action of updating the working tree to a revision which was
-	stored in the object database.
-
-cherry-picking::
-	In SCM jargon, "cherry pick" means to choose a subset of
-	changes out of a series of changes (typically commits)
-	and record them as a new series of changes on top of
-	different codebase.  In GIT, this is performed by
-	"git cherry-pick" command to extract the change
-	introduced by an existing commit and to record it based
-	on the tip of the current branch as a new commit.
-
-clean::
-	A working tree is clean, if it corresponds to the revision
-	referenced by the current head.  Also see "dirty".
-
-commit::
-	As a verb: The action of storing the current state of the index in the
-	object database. The result is a revision.
-	As a noun: Short hand for commit object.
-
-commit object::
-	An object which contains the information about a particular
-	revision, such as parents, committer, author, date and the
-	tree object which corresponds to the top directory of the
-	stored revision.
-
-core git::
-	Fundamental data structures and utilities of git. Exposes only
-	limited source code management tools.
-
-DAG::
-	Directed acyclic graph. The commit objects form a directed acyclic
-	graph, because they have parents (directed), and the graph of commit
-	objects is acyclic (there is no chain which begins and ends with the
-	same object).
-
-dangling object::
-	An unreachable object which is not reachable even from other
-	unreachable objects; a dangling object has no references to it
-	from any reference or object in the repository.
-
-dircache::
-	You are *waaaaay* behind.
-
-dirty::
-	A working tree is said to be dirty if it contains modifications
-	which have not been committed to the current branch.
-
-directory::
-	The list you get with "ls" :-)
-
-ent::
-	Favorite synonym to "tree-ish" by some total geeks. See
-	`http://en.wikipedia.org/wiki/Ent_(Middle-earth)` for an in-depth
-	explanation.  Avoid this term, not to confuse people.
-
-fast forward::
-	A fast-forward is a special type of merge where you have
-	a revision and you are "merging" another branch's changes
-	that happen to be a descendant of what you have.
-	In such these cases, you do not make a new merge commit but
-	instead just update to his revision. This will happen
-	frequently on a tracking branch of a remote repository.
-
-fetch::
-	Fetching a branch means to get the branch's head ref from a
-	remote repository, to find out which objects are missing from
-	the local object database, and to get them, too.
-
-file system::
-	Linus Torvalds originally designed git to be a user space file
-	system, i.e. the infrastructure to hold files and directories.
-	That ensured the efficiency and speed of git.
-
-git archive::
-	Synonym for repository (for arch people).
-
-grafts::
-	Grafts enables two otherwise different lines of development to be
-	joined together by recording fake ancestry information for commits.
-	This way you can make git pretend the set of parents a commit
-	has is different from what was recorded when the commit was created.
-	Configured via the `.git/info/grafts` file.
-
-hash::
-	In git's context, synonym to object name.
-
-head::
-	The top of a branch. It contains a ref to the corresponding
-	commit object.
-
-head ref::
-	A ref pointing to a head. Often, this is abbreviated to "head".
-	Head refs are stored in `$GIT_DIR/refs/heads/`.
-
-hook::
-	During the normal execution of several git commands,
-	call-outs are made to optional scripts that allow
-	a developer to add functionality or checking.
-	Typically, the hooks allow for a command to be pre-verified
-	and potentially aborted, and allow for a post-notification
-	after the operation is done.
-	The hook scripts are found in the `$GIT_DIR/hooks/` directory,
-	and are enabled by simply making them executable.
-
-index::
-	A collection of files with stat information, whose contents are
-	stored as objects. The index is a stored version of your working
-	tree. Truth be told, it can also contain a second, and even a third
-	version of a working tree, which are used when merging.
-
-index entry::
-	The information regarding a particular file, stored in the index.
-	An index entry can be unmerged, if a merge was started, but not
-	yet finished (i.e. if the index contains multiple versions of
-	that file).
-
-master::
-	The default development branch. Whenever you create a git
-	repository, a branch named "master" is created, and becomes
-	the active branch. In most cases, this contains the local
-	development, though that is purely conventional and not required.
-
-merge::
-	To merge branches means to try to accumulate the changes since a
-	common ancestor and apply them to the first branch. An automatic
-	merge uses heuristics to accomplish that. Evidently, an automatic
-	merge can fail.
-
-object::
-	The unit of storage in git. It is uniquely identified by
-	the SHA1 of its contents. Consequently, an object can not
-	be changed.
-
-object database::
-	Stores a set of "objects", and an individual object is identified
-	by its object name. The objects usually live in `$GIT_DIR/objects/`.
-
-object identifier::
-	Synonym for object name.
-
-object name::
-	The unique identifier of an object. The hash of the object's contents
-	using the Secure Hash Algorithm 1 and usually represented by the 40
-	character hexadecimal encoding of the hash of the object (possibly
-	followed by a white space).
-
-object type::
-	One of the identifiers "commit","tree","tag" and "blob" describing
-	the type of an object.
-
-octopus::
-	To merge more than two branches. Also denotes an intelligent
-	predator.
-
-origin::
-	The default upstream repository. Most projects have at
-	least one upstream project which they track. By default
-	'origin' is used for that purpose.  New upstream updates
-	will be fetched into remote tracking branches named
-	origin/name-of-upstream-branch, which you can see using
-	"git branch -r".
-
-pack::
-	A set of objects which have been compressed into one file (to save
-	space or to transmit them efficiently).
-
-pack index::
-	The list of identifiers, and other information, of the objects in a
-	pack, to assist in efficiently accessing the contents of a pack.
-
-parent::
-	A commit object contains a (possibly empty) list of the logical
-	predecessor(s) in the line of development, i.e. its parents.
-
-pickaxe::
-	The term pickaxe refers to an option to the diffcore routines
-	that help select changes that add or delete a given text string.
-	With the --pickaxe-all option, it can be used to view the
-	full changeset that introduced or removed, say, a particular
-	line of text.  See gitlink:git-diff[1].
-
-plumbing::
-	Cute name for core git.
-
-porcelain::
-	Cute name for programs and program suites depending on core git,
-	presenting a high level access to core git. Porcelains expose
-	more of a SCM interface than the plumbing.
-
-pull::
-	Pulling a branch means to fetch it and merge it.
-
-push::
-	Pushing a branch means to get the branch's head ref from a remote
-	repository, find out if it is an ancestor to the branch's local
-	head ref is a direct, and in that case, putting all objects, which
-	are reachable from the local head ref, and which are missing from
-	the remote repository, into the remote object database, and updating
-	the remote head ref. If the remote head is not an ancestor to the
-	local head, the push fails.
-
-reachable::
-	All of the ancestors of a given commit are said to be reachable from
-	that commit.  More generally, one object is reachable from another if
-	we can reach the one from the other by a chain that follows tags to
-	whatever they tag, commits to their parents or trees, and trees to the
-	trees or blobs that they contain.
-
-rebase::
-	To clean a branch by starting from the head of the main line of
-	development ("master"), and reapply the (possibly cherry-picked)
-	changes from that branch.
-
-ref::
-	A 40-byte hex representation of a SHA1 or a name that denotes
-	a particular object. These may be stored in `$GIT_DIR/refs/`.
-
-refspec::
-	A refspec is used by fetch and push to describe the mapping
-	between remote ref and local ref.  They are combined with
-	a colon in the format <src>:<dst>, preceded by an optional
-	plus sign, +.  For example:
-	`git fetch $URL refs/heads/master:refs/heads/origin`
-	means "grab the master branch head from the $URL and store
-	it as my origin branch head".
-	And `git push $URL refs/heads/master:refs/heads/to-upstream`
-	means "publish my master branch head as to-upstream branch
-	at $URL".   See also gitlink:git-push[1]
-
-repository::
-	A collection of refs together with an object database containing
-	all objects, which are reachable from the refs, possibly accompanied
-	by meta data from one or more porcelains. A repository can
-	share an object database with other repositories.
-
-resolve::
-	The action of fixing up manually what a failed automatic merge
-	left behind.
-
-revision::
-	A particular state of files and directories which was stored in
-	the object database. It is referenced by a commit object.
-
-rewind::
-	To throw away part of the development, i.e. to assign the head to
-	an earlier revision.
-
-SCM::
-	Source code management (tool).
-
-SHA1::
-	Synonym for object name.
-
-shallow repository::
-	A shallow repository has an incomplete history some of
-	whose commits have parents cauterized away (in other
-	words, git is told to pretend that these commits do not
-	have the parents, even though they are recorded in the
-	commit object).  This is sometimes useful when you are
-	interested only in the recent history of a project even
-	though the real history recorded in the upstream is
-	much larger.  A shallow repository is created by giving
-	`--depth` option to gitlink:git-clone[1], and its
-	history can be later deepened with gitlink:git-fetch[1].
-
-symref::
-	Symbolic reference: instead of containing the SHA1 id itself, it
-	is of the format 'ref: refs/some/thing' and when referenced, it
-	recursively dereferences to this reference. 'HEAD' is a prime
-	example of a symref. Symbolic references are manipulated with
-	the gitlink:git-symbolic-ref[1] command.
-
-topic branch::
-	A regular git branch that is used by a developer to
-	identify a conceptual line of development.  Since branches
-	are very easy and inexpensive, it is often desirable to
-	have several small branches that each contain very well
-	defined concepts or small incremental yet related changes.
-
-tracking branch::
-	A regular git branch that is used to follow changes from
-	another repository.  A tracking branch should not contain
-	direct modifications or have local commits made to it.
-	A tracking branch can usually be identified as the
-	right-hand-side ref in a Pull: refspec.
-
-tree object::
-	An object containing a list of file names and modes along with refs
-	to the associated blob and/or tree objects. A tree is equivalent
-	to a directory.
-
-tree::
-	Either a working tree, or a tree object together with the
-	dependent blob and tree objects (i.e. a stored representation
-	of a working tree).
-
-tree-ish::
-	A ref pointing to either a commit object, a tree object, or a
-	tag object pointing to a tag or commit or tree object.
-
-tag object::
-	An object containing a ref pointing to another object, which can
-	contain a message just like a commit object. It can also
-	contain a (PGP) signature, in which case it is called a "signed
-	tag object".
-
-tag::
-	A ref pointing to a tag or commit object. In contrast to a head,
-	a tag is not changed by a commit. Tags (not tag objects) are
-	stored in `$GIT_DIR/refs/tags/`. A git tag has nothing to do with
-	a Lisp tag (which is called object type in git's context).
-	A tag is most typically used to mark a particular point in the
-	commit ancestry chain.
-
-unmerged index::
-	An index which contains unmerged index entries.
-
-unreachable object::
-	An object which is not reachable from a branch, tag, or any
-	other reference.
-
-working tree::
-	The set of files and directories currently being worked on,
-	i.e. you can work in your working tree without using git at all.

-Hooks used by git
-=================
-
-Hooks are little scripts you can place in `$GIT_DIR/hooks`
-directory to trigger action at certain points.  When
-`git-init` is run, a handful example hooks are copied in the
-`hooks` directory of the new repository, but by default they are
-all disabled.  To enable a hook, make it executable with `chmod +x`.
-
-This document describes the currently defined hooks.
-
-applypatch-msg
---------------
-
-This hook is invoked by `git-applypatch` script, which is
-typically invoked by `git-applymbox`.  It takes a single
-parameter, the name of the file that holds the proposed commit
-log message.  Exiting with non-zero status causes
-`git-applypatch` to abort before applying the patch.
-
-The hook is allowed to edit the message file in place, and can
-be used to normalize the message into some project standard
-format (if the project has one). It can also be used to refuse
-the commit after inspecting the message file.
-
-The default 'applypatch-msg' hook, when enabled, runs the
-'commit-msg' hook, if the latter is enabled.
-
-pre-applypatch
---------------
-
-This hook is invoked by `git-applypatch` script, which is
-typically invoked by `git-applymbox`.  It takes no parameter,
-and is invoked after the patch is applied, but before a commit
-is made.  Exiting with non-zero status causes the working tree
-after application of the patch not committed.
-
-It can be used to inspect the current working tree and refuse to
-make a commit if it does not pass certain test.
-
-The default 'pre-applypatch' hook, when enabled, runs the
-'pre-commit' hook, if the latter is enabled.
-
-post-applypatch
----------------
-
-This hook is invoked by `git-applypatch` script, which is
-typically invoked by `git-applymbox`.  It takes no parameter,
-and is invoked after the patch is applied and a commit is made.
-
-This hook is meant primarily for notification, and cannot affect
-the outcome of `git-applypatch`.
-
-pre-commit
-----------
-
-This hook is invoked by `git-commit`, and can be bypassed
-with `\--no-verify` option.  It takes no parameter, and is
-invoked before obtaining the proposed commit log message and
-making a commit.  Exiting with non-zero status from this script
-causes the `git-commit` to abort.
-
-The default 'pre-commit' hook, when enabled, catches introduction
-of lines with trailing whitespaces and aborts the commit when
-such a line is found.
-
-commit-msg
-----------
-
-This hook is invoked by `git-commit`, and can be bypassed
-with `\--no-verify` option.  It takes a single parameter, the
-name of the file that holds the proposed commit log message.
-Exiting with non-zero status causes the `git-commit` to
-abort.
-
-The hook is allowed to edit the message file in place, and can
-be used to normalize the message into some project standard
-format (if the project has one). It can also be used to refuse
-the commit after inspecting the message file.
-
-The default 'commit-msg' hook, when enabled, detects duplicate
-"Signed-off-by" lines, and aborts the commit if one is found.
-
-post-commit
------------
-
-This hook is invoked by `git-commit`.  It takes no
-parameter, and is invoked after a commit is made.
-
-This hook is meant primarily for notification, and cannot affect
-the outcome of `git-commit`.
-
-update
-------
-
-This hook is invoked by `git-receive-pack` on the remote repository,
-which happens when a `git push` is done on a local repository.
-Just before updating the ref on the remote repository, the update hook
-is invoked.  Its exit status determines the success or failure of
-the ref update.
-
-The hook executes once for each ref to be updated, and takes
-three parameters:
-
- - the name of the ref being updated,
- - the old object name stored in the ref,
- - and the new objectname to be stored in the ref.
-
-A zero exit from the update hook allows the ref to be updated.
-Exiting with a non-zero status prevents `git-receive-pack`
-from updating the ref.
-
-This hook can be used to prevent 'forced' update on certain refs by
-making sure that the object name is a commit object that is a
-descendant of the commit object named by the old object name.
-That is, to enforce a "fast forward only" policy.
-
-It could also be used to log the old..new status.  However, it
-does not know the entire set of branches, so it would end up
-firing one e-mail per ref when used naively, though.
-
-Another use suggested on the mailing list is to use this hook to
-implement access control which is finer grained than the one
-based on filesystem group.
-
-The standard output of this hook is sent to `stderr`, so if you
-want to report something to the `git-send-pack` on the other end,
-you can simply `echo` your messages.
-
-The default 'update' hook, when enabled, demonstrates how to
-send out a notification e-mail.
-
-post-update
------------
-
-This hook is invoked by `git-receive-pack` on the remote repository,
-which happens when a `git push` is done on a local repository.
-It executes on the remote repository once after all the refs have
-been updated.
-
-It takes a variable number of parameters, each of which is the
-name of ref that was actually updated.
-
-This hook is meant primarily for notification, and cannot affect
-the outcome of `git-receive-pack`.
-
-The 'post-update' hook can tell what are the heads that were pushed,
-but it does not know what their original and updated values are,
-so it is a poor place to do log old..new.
-
-When enabled, the default 'post-update' hook runs
-`git-update-server-info` to keep the information used by dumb
-transports (e.g., HTTP) up-to-date.  If you are publishing
-a git repository that is accessible via HTTP, you should
-probably enable this hook.
-
-The standard output of this hook is sent to `/dev/null`; if you
-want to report something to the `git-send-pack` on the other end,
-you can redirect your output to your `stderr`.

-
-The most common situation is that you've rebased a branch (or you have
-pulled from somebody else who rebased a branch, like the "pu" branch in
-the git.git archive itself).
-
-What happens is that the old head of the original branch still exists, as
-does obviously everything it pointed to. The branch pointer itself just
-doesn't, since you replaced it with another one.
-
-However, there are certainly other situations too that cause dangling
-objects. For example, the "dangling blob" situation you have tends to be
-because you did a "git add" of a file, but then, before you actually
-committed it and made it part of the bigger picture, you changed something
-else in that file and committed that *updated* thing - the old state that
-you added originally ends up not being pointed to by any commit/tree, so
-it's now a dangling blob object.
-
-Similarly, when the "recursive" merge strategy runs, and finds that there
-are criss-cross merges and thus more than one merge base (which is fairly
-unusual, but it does happen), it will generate one temporary midway tree
-(or possibly even more, if you had lots of criss-crossing merges and
-more than two merge bases) as a temporary internal merge base, and again,
-those are real objects, but the end result will not end up pointing to
-them, so they end up "dangling" in your repository.
-
-Generally, dangling objects aren't anything to worry about. They can even
-be very useful: if you screw something up, the dangling objects can be how
-you recover your old tree (say, you did a rebase, and realized that you
-really didn't want to - you can look at what dangling objects you have,
-and decide to reset your head to some old dangling state).
-
-For commits, the most useful thing to do with dangling objects tends to be
-to do a simple
-
-	gitk <dangling-commit-sha-goes-here> --not --all
-
-which means exactly what it sounds like: it says that you want to see the
-commit history that is described by the dangling commit(s), but you do NOT
-want to see the history that is described by all your branches and tags
-(which are the things you normally reach). That basically shows you in a
-nice way what the danglign commit was (and notice that it might not be
-just one commit: we only report the "tip of the line" as being dangling,
-but there might be a whole deep and complex commit history that has gotten
-dropped - rebasing will do that).
-
-For blobs and trees, you can't do the same, but you can examine them. You
-can just do
-
-	git show <dangling-blob/tree-sha-goes-here>
-
-to show what the contents of the blob were (or, for a tree, basically what
-the "ls" for that directory was), and that may give you some idea of what
-the operation was that left that dangling object.
-
-Usually, dangling blobs and trees aren't very interesting. They're almost
-always the result of either being a half-way mergebase (the blob will
-often even have the conflict markers from a merge in it, if you have had
-conflicting merges that you fixed up by hand), or simply because you
-interrupted a "git fetch" with ^C or something like that, leaving _some_
-of the new objects in the object database, but just dangling and useless.
-
-Anyway, once you are sure that you're not interested in any dangling
-state, you can just prune all unreachable objects:
-
-	git prune
-
-and they'll be gone. But you should only run "git prune" on a quiescent
-repository - it's kind of like doing a filesystem fsck recovery: you don't
-want to do that while the filesystem is mounted.
-
-(The same is true of "git-fsck-objects" itself, btw - but since
-git-fsck-objects never actually *changes* the repository, it just reports
-on what it found, git-fsck-objects itself is never "dangerous" to run.
-Running it while somebody is actually changing the repository can cause
-confusing and scary messages, but it won't actually do anything bad. In
-contrast, running "git prune" while somebody is actively changing the
-repository is a *BAD* idea).

-head of "master", since that's what you just tried to boot and failed at). 
-Also, figure out the most recent known-good commit (usually the _previous_ 
-kernel you ran: and if you've only done a single "pull" in between, it 
-will be ORIG_HEAD).
-
-Then do
-
-	git bisect start
-	git bisect bad master		<- mark "master" as the bad state
-	git bisect good ORIG_HEAD	<- mark ORIG_HEAD as good (or
-					   whatever other known-good 
-					   thing you booted last)
-
-and at this point "git bisect" will churn for a while, and tell you what 
-the mid-point between those two commits are, and check that state out as 
-the head of the new "bisect" branch.
-
-Compile and reboot.
-
-If it's good, just do
-
-	git bisect good		<- mark current head as good
-
-otherwise, reboot into a good kernel instead, and do (surprise surprise, 
-git really is very intuitive):
-
-	git bisect bad		<- mark current head as bad
-
-and whatever you do, git will select a new half-way point. Do this for a 
-while, until git tells you exactly which commit was the first bad commit. 
-That's your culprit.
-
-It really works wonderfully well, except for the case where there was 
-_another_ commit that broke something in between, like introduced some 
-stupid compile error. In that case you should not mark that commit good or 
-bad: you should try to find another commit close-by, and do a "git reset 
---hard <newcommit>" to try out _that_ commit instead, and then test that 
-instead (and mark it good or bad).
-
-You can do "git bisect visualize" while you do all this to see what's 
-going on by starting up gitk on the bisection range.
-
-Finally, once you've figured out exactly which commit was bad, you can 
-then go back to the master branch, and try reverting just that commit:
-
-	git checkout master
-	git revert <bad-commit-id>
-
-to verify that the top-of-kernel works with that single commit reverted.

+Subject: Beginner question on "Pull is mostly evil"
+Abstract: This how-to explains a method for keeping a
+ project's history correct when using git pull.
+Content-type: text/asciidoc
+
+Keep authoritative canonical history correct with git pull
+==========================================================
+
+Sometimes a new project integrator will end up with project history
+that appears to be "backwards" from what other project developers
+expect. This howto presents a suggested integration workflow for
+maintaining a central repository.
+
+Suppose that that central repository has this history:
+
+------------
+    ---o---o---A
+------------
+
+which ends at commit `A` (time flows from left to right and each node
+in the graph is a commit, lines between them indicating parent-child
+relationship).
+
+Then you clone it and work on your own commits, which leads you to
+have this history in *your* repository:
+
+------------
+    ---o---o---A---B---C
+------------
+
+Imagine your coworker did the same and built on top of `A` in *his*
+repository in the meantime, and then pushed it to the
+central repository:
+
+------------
+    ---o---o---A---X---Y---Z
+------------
+
+Now, if you `git push` at this point, because your history that leads
+to `C` lacks `X`, `Y` and `Z`, it will fail.  You need to somehow make
+the tip of your history a descendant of `Z`.
+
+One suggested way to solve the problem is "fetch and then merge", aka
+`git pull`. When you fetch, your repository will have a history like
+this:
+
+------------
+    ---o---o---A---B---C
+		\
+		 X---Y---Z
+------------
+
+Once you run merge after that, while still on *your* branch, i.e. `C`,
+you will create a merge `M` and make the history look like this:
+
+------------
+    ---o---o---A---B---C---M
+		\         /
+		 X---Y---Z
+------------
+
+`M` is a descendant of `Z`, so you can push to update the central
+repository.  Such a merge `M` does not lose any commit in both
+histories, so in that sense it may not be wrong, but when people want
+to talk about "the authoritative canonical history that is shared
+among the project participants", i.e. "the trunk", they often view
+it as "commits you see by following the first-parent chain", and use
+this command to view it:
+
+------------
+    $ git log --first-parent
+------------
+
+For all other people who observed the central repository after your
+coworker pushed `Z` but before you pushed `M`, the commit on the trunk
+used to be `o-o-A-X-Y-Z`.  But because you made `M` while you were on
+`C`, `M`'s first parent is `C`, so by pushing `M` to advance the
+central repository, you made `X-Y-Z` a side branch, not on the trunk.
+
+You would rather want to have a history of this shape:
+
+------------
+    ---o---o---A---X---Y---Z---M'
+		\             /
+		 B-----------C
+------------
+
+so that in the first-parent chain, it is clear that the project first
+did `X` and then `Y` and then `Z` and merged a change that consists of
+two commits `B` and `C` that achieves a single goal.  You may have
+worked on fixing the bug #12345 with these two patches, and the merge
+`M'` with swapped parents can say in its log message "Merge
+fix-bug-12345". Having a way to tell `git pull` to create a merge
+but record the parents in reverse order may be a way to do so.
+
+Note that I said "achieves a single goal" above, because this is
+important.  "Swapping the merge order" only covers a special case
+where the project does not care too much about having unrelated
+things done on a single merge but cares a lot about first-parent
+chain.
+
+There are multiple schools of thought about the "trunk" management.
+
+ 1. Some projects want to keep a completely linear history without any
+    merges.  Obviously, swapping the merge order would not match their
+    taste.  You would need to flatten your history on top of the
+    updated upstream to result in a history of this shape instead:
++
+------------
+    ---o---o---A---X---Y---Z---B---C
+------------
++
+with `git pull --rebase` or something.
+
+ 2. Some projects tolerate merges in their history, but do not worry
+    too much about the first-parent order, and allow fast-forward
+    merges.  To them, swapping the merge order does not hurt, but
+    it is unnecessary.
+
+ 3. Some projects want each commit on the "trunk" to do one single
+    thing.  The output of `git log --first-parent` in such a project
+    would show either a merge of a side branch that completes a single
+    theme, or a single commit that completes a single theme by itself.
+    If your two commits `B` and `C` (or they may even be two groups of
+    commits) were solving two independent issues, then the merge `M'`
+    we made in the earlier example by swapping the merge order is
+    still not up to the project standard.  It merges two unrelated
+    efforts `B` and `C` at the same time.
+
+For projects in the last category (Git itself is one of them),
+individual developers would want to prepare a history more like
+this:
+
+------------
+		 C0--C1--C2     topic-c
+		/
+    ---o---o---A                master
+		\
+		 B0--B1--B2     topic-b
+------------
+
+That is, keeping separate topics on separate branches, perhaps like
+so:
+
+------------
+    $ git clone $URL work && cd work
+    $ git checkout -b topic-b master
+    $ ... work to create B0, B1 and B2 to complete one theme
+    $ git checkout -b topic-c master
+    $ ... same for the theme of topic-c
+------------
+
+And then
+
+------------
+    $ git checkout master
+    $ git pull --ff-only
+------------
+
+would grab `X`, `Y` and `Z` from the upstream and advance your master
+branch:
+
+------------
+		 C0--C1--C2     topic-c
+		/
+    ---o---o---A---X---Y---Z    master
+		\
+		 B0--B1--B2     topic-b
+------------
+
+And then you would merge these two branches separately:
+
+------------
+    $ git merge topic-b
+    $ git merge topic-c
+------------
+
+to result in
+
+------------
+		 C0--C1---------C2
+		/                 \
+    ---o---o---A---X---Y---Z---M---N
+		\             /
+		 B0--B1-----B2
+------------
+
+and push it back to the central repository.
+
+It is very much possible that while you are merging topic-b and
+topic-c, somebody again advanced the history in the central repository
+to put `W` on top of `Z`, and make your `git push` fail.
+
+In such a case, you would rewind to discard `M` and `N`, update the
+tip of your 'master' again and redo the two merges:
+
+------------
+    $ git reset --hard origin/master
+    $ git pull --ff-only
+    $ git merge topic-b
+    $ git merge topic-c
+------------
+
+The procedure will result in a history that looks like this:
+
+------------
+		 C0--C1--------------C2
+		/                     \
+    ---o---o---A---X---Y---Z---W---M'--N'
+		\                 /
+		 B0--B1---------B2
+------------

+Subject: Addendum to "MaintNotes"
+Abstract: Imagine that Git development is racing along as usual, when our friendly
+ neighborhood maintainer is struck down by a wayward bus. Out of the
+ hordes of suckers (loyal developers), you have been tricked (chosen) to
+ step up as the new maintainer. This howto will show you "how to" do it.
+Content-type: text/asciidoc
+
+How to maintain Git
+===================
+
+Activities
+----------
+
+The maintainer's Git time is spent on three activities.
+
+ - Communication (45%)
+
+   Mailing list discussions on general design, fielding user
+   questions, diagnosing bug reports; reviewing, commenting on,
+   suggesting alternatives to, and rejecting patches.
+
+ - Integration (50%)
+
+   Applying new patches from the contributors while spotting and
+   correcting minor mistakes, shuffling the integration and
+   testing branches, pushing the results out, cutting the
+   releases, and making announcements.
+
+ - Own development (5%)
+
+   Scratching my own itch and sending proposed patch series out.
+
+The Policy
+----------
+
+The policy on Integration is informally mentioned in "A Note
+from the maintainer" message, which is periodically posted to
+this mailing list after each feature release is made.
+
+ - Feature releases are numbered as vX.Y.0 and are meant to
+   contain bugfixes and enhancements in any area, including
+   functionality, performance and usability, without regression.
+
+ - One release cycle for a feature release is expected to last for
+   eight to ten weeks.
+
+ - Maintenance releases are numbered as vX.Y.Z and are meant
+   to contain only bugfixes for the corresponding vX.Y.0 feature
+   release and earlier maintenance releases vX.Y.W (W < Z).
+
+ - 'master' branch is used to prepare for the next feature
+   release. In other words, at some point, the tip of 'master'
+   branch is tagged with vX.Y.0.
+
+ - 'maint' branch is used to prepare for the next maintenance
+   release.  After the feature release vX.Y.0 is made, the tip
+   of 'maint' branch is set to that release, and bugfixes will
+   accumulate on the branch, and at some point, the tip of the
+   branch is tagged with vX.Y.1, vX.Y.2, and so on.
+
+ - 'next' branch is used to publish changes (both enhancements
+   and fixes) that (1) have worthwhile goal, (2) are in a fairly
+   good shape suitable for everyday use, (3) but have not yet
+   demonstrated to be regression free.  New changes are tested
+   in 'next' before merged to 'master'.
+
+ - 'pu' branch is used to publish other proposed changes that do
+   not yet pass the criteria set for 'next'.
+
+ - The tips of 'master' and 'maint' branches will not be rewound to
+   allow people to build their own customization on top of them.
+   Early in a new development cycle, 'next' is rewound to the tip of
+   'master' once, but otherwise it will not be rewound until the end
+   of the cycle.
+
+ - Usually 'master' contains all of 'maint' and 'next' contains all
+   of 'master'.  'pu' contains all the topics merged to 'next', but
+   is rebuilt directly on 'master'.
+
+ - The tip of 'master' is meant to be more stable than any
+   tagged releases, and the users are encouraged to follow it.
+
+ - The 'next' branch is where new action takes place, and the
+   users are encouraged to test it so that regressions and bugs
+   are found before new topics are merged to 'master'.
+
+Note that before v1.9.0 release, the version numbers used to be
+structured slightly differently.  vX.Y.Z were feature releases while
+vX.Y.Z.W were maintenance releases for vX.Y.Z.
+
+
+A Typical Git Day
+-----------------
+
+A typical Git day for the maintainer implements the above policy
+by doing the following:
+
+ - Scan mailing list.  Respond with review comments, suggestions
+   etc.  Kibitz.  Collect potentially usable patches from the
+   mailing list.  Patches about a single topic go to one mailbox (I
+   read my mail in Gnus, and type \C-o to save/append messages in
+   files in mbox format).
+
+ - Write his own patches to address issues raised on the list but
+   nobody has stepped up solving.  Send it out just like other
+   contributors do, and pick them up just like patches from other
+   contributors (see above).
+
+ - Review the patches in the saved mailboxes.  Edit proposed log
+   message for typofixes and clarifications, and add Acks
+   collected from the list.  Edit patch to incorporate "Oops,
+   that should have been like this" fixes from the discussion.
+
+ - Classify the collected patches and handle 'master' and
+   'maint' updates:
+
+   - Obviously correct fixes that pertain to the tip of 'maint'
+     are directly applied to 'maint'.
+
+   - Obviously correct fixes that pertain to the tip of 'master'
+     are directly applied to 'master'.
+
+   - Other topics are not handled in this step.
+
+   This step is done with "git am".
+
+     $ git checkout master    ;# or "git checkout maint"
+     $ git am -sc3 mailbox
+     $ make test
+
+   In practice, almost no patch directly goes to 'master' or
+   'maint'.
+
+ - Review the last issue of "What's cooking" message, review the
+   topics ready for merging (topic->master and topic->maint).  Use
+   "Meta/cook -w" script (where Meta/ contains a checkout of the
+   'todo' branch) to aid this step.
+
+   And perform the merge.  Use "Meta/Reintegrate -e" script (see
+   later) to aid this step.
+
+     $ Meta/cook -w last-issue-of-whats-cooking.mbox
+
+     $ git checkout master    ;# or "git checkout maint"
+     $ echo ai/topic | Meta/Reintegrate -e ;# "git merge ai/topic"
+     $ git log -p ORIG_HEAD.. ;# final review
+     $ git diff ORIG_HEAD..   ;# final review
+     $ make test              ;# final review
+
+ - Handle the remaining patches:
+
+   - Anything unobvious that is applicable to 'master' (in other
+     words, does not depend on anything that is still in 'next'
+     and not in 'master') is applied to a new topic branch that
+     is forked from the tip of 'master'.  This includes both
+     enhancements and unobvious fixes to 'master'.  A topic
+     branch is named as ai/topic where "ai" is two-letter string
+     named after author's initial and "topic" is a descriptive name
+     of the topic (in other words, "what's the series is about").
+
+   - An unobvious fix meant for 'maint' is applied to a new
+     topic branch that is forked from the tip of 'maint'.  The
+     topic is named as ai/maint-topic.
+
+   - Changes that pertain to an existing topic are applied to
+     the branch, but:
+
+     - obviously correct ones are applied first;
+
+     - questionable ones are discarded or applied to near the tip;
+
+   - Replacement patches to an existing topic are accepted only
+     for commits not in 'next'.
+
+   The above except the "replacement" are all done with:
+
+     $ git checkout ai/topic ;# or "git checkout -b ai/topic master"
+     $ git am -sc3 mailbox
+
+   while patch replacement is often done by:
+
+     $ git format-patch ai/topic~$n..ai/topic ;# export existing
+
+   then replace some parts with the new patch, and reapplying:
+
+     $ git checkout ai/topic
+     $ git reset --hard ai/topic~$n
+     $ git am -sc3 -s 000*.txt
+
+   The full test suite is always run for 'maint' and 'master'
+   after patch application; for topic branches the tests are run
+   as time permits.
+
+ - Merge maint to master as needed:
+
+     $ git checkout master
+     $ git merge maint
+     $ make test
+
+ - Merge master to next as needed:
+
+     $ git checkout next
+     $ git merge master
+     $ make test
+
+ - Review the last issue of "What's cooking" again and see if topics
+   that are ready to be merged to 'next' are still in good shape
+   (e.g. has there any new issue identified on the list with the
+   series?)
+
+ - Prepare 'jch' branch, which is used to represent somewhere
+   between 'master' and 'pu' and often is slightly ahead of 'next'.
+
+     $ Meta/Reintegrate master..pu >Meta/redo-jch.sh
+
+   The result is a script that lists topics to be merged in order to
+   rebuild 'pu' as the input to Meta/Reintegrate script.  Remove
+   later topics that should not be in 'jch' yet.  Add a line that
+   consists of '### match next' before the name of the first topic
+   in the output that should be in 'jch' but not in 'next' yet.
+
+ - Now we are ready to start merging topics to 'next'.  For each
+   branch whose tip is not merged to 'next', one of three things can
+   happen:
+
+   - The commits are all next-worthy; merge the topic to next;
+   - The new parts are of mixed quality, but earlier ones are
+     next-worthy; merge the early parts to next;
+   - Nothing is next-worthy; do not do anything.
+
+   This step is aided with Meta/redo-jch.sh script created earlier.
+   If a topic that was already in 'next' gained a patch, the script
+   would list it as "ai/topic~1".  To include the new patch to the
+   updated 'next', drop the "~1" part; to keep it excluded, do not
+   touch the line.  If a topic that was not in 'next' should be
+   merged to 'next', add it at the end of the list.  Then:
+
+     $ git checkout -B jch master
+     $ Meta/redo-jch.sh -c1
+
+   to rebuild the 'jch' branch from scratch.  "-c1" tells the script
+   to stop merging at the first line that begins with '###'
+   (i.e. the "### match next" line you added earlier).
+
+   At this point, build-test the result.  It may reveal semantic
+   conflicts (e.g. a topic renamed a variable, another added a new
+   reference to the variable under its old name), in which case
+   prepare an appropriate merge-fix first (see appendix), and
+   rebuild the 'jch' branch from scratch, starting at the tip of
+   'master'.
+
+   Then do the same to 'next'
+
+     $ git checkout next
+     $ sh Meta/redo-jch.sh -c1 -e
+
+   The "-e" option allows the merge message that comes from the
+   history of the topic and the comments in the "What's cooking" to
+   be edited.  The resulting tree should match 'jch' as the same set
+   of topics are merged on 'master'; otherwise there is a mismerge.
+   Investigate why and do not proceed until the mismerge is found
+   and rectified.
+
+     $ git diff jch next
+
+   When all is well, clean up the redo-jch.sh script with
+
+     $ sh Meta/redo-jch.sh -u
+
+   This removes topics listed in the script that have already been
+   merged to 'master'.  This may lose '### match next' marker;
+   add it again to the appropriate place when it happens.
+
+ - Rebuild 'pu'.
+
+     $ Meta/Reintegrate master..pu >Meta/redo-pu.sh
+
+   Edit the result by adding new topics that are not still in 'pu'
+   in the script.  Then
+
+     $ git checkout -B pu jch
+     $ sh Meta/redo-pu.sh
+
+   When all is well, clean up the redo-pu.sh script with
+
+     $ sh Meta/redo-pu.sh -u
+
+   Double check by running
+
+     $ git branch --no-merged pu
+
+   to see there is no unexpected leftover topics.
+
+   At this point, build-test the result for semantic conflicts, and
+   if there are, prepare an appropriate merge-fix first (see
+   appendix), and rebuild the 'pu' branch from scratch, starting at
+   the tip of 'jch'.
+
+ - Update "What's cooking" message to review the updates to
+   existing topics, newly added topics and graduated topics.
+
+   This step is helped with Meta/cook script.
+
+     $ Meta/cook
+
+   This script inspects the history between master..pu, finds tips
+   of topic branches, compares what it found with the current
+   contents in Meta/whats-cooking.txt, and updates that file.
+   Topics not listed in the file but are found in master..pu are
+   added to the "New topics" section, topics listed in the file that
+   are no longer found in master..pu are moved to the "Graduated to
+   master" section, and topics whose commits changed their states
+   (e.g. used to be only in 'pu', now merged to 'next') are updated
+   with change markers "<<" and ">>".
+
+   Look for lines enclosed in "<<" and ">>"; they hold contents from
+   old file that are replaced by this integration round.  After
+   verifying them, remove the old part.  Review the description for
+   each topic and update its doneness and plan as needed.  To review
+   the updated plan, run
+
+     $ Meta/cook -w
+
+   which will pick up comments given to the topics, such as "Will
+   merge to 'next'", etc. (see Meta/cook script to learn what kind
+   of phrases are supported).
+
+ - Compile, test and install all four (five) integration branches;
+   Meta/Dothem script may aid this step.
+
+ - Format documentation if the 'master' branch was updated;
+   Meta/dodoc.sh script may aid this step.
+
+ - Push the integration branches out to public places; Meta/pushall
+   script may aid this step.
+
+Observations
+------------
+
+Some observations to be made.
+
+ * Each topic is tested individually, and also together with other
+   topics cooking first in 'pu', then in 'jch' and then in 'next'.
+   Until it matures, no part of it is merged to 'master'.
+
+ * A topic already in 'next' can get fixes while still in
+   'next'.  Such a topic will have many merges to 'next' (in
+   other words, "git log --first-parent next" will show many
+   "Merge branch 'ai/topic' to next" for the same topic.
+
+ * An unobvious fix for 'maint' is cooked in 'next' and then
+   merged to 'master' to make extra sure it is Ok and then
+   merged to 'maint'.
+
+ * Even when 'next' becomes empty (in other words, all topics
+   prove stable and are merged to 'master' and "git diff master
+   next" shows empty), it has tons of merge commits that will
+   never be in 'master'.
+
+ * In principle, "git log --first-parent master..next" should
+   show nothing but merges (in practice, there are fixup commits
+   and reverts that are not merges).
+
+ * Commits near the tip of a topic branch that are not in 'next'
+   are fair game to be discarded, replaced or rewritten.
+   Commits already merged to 'next' will not be.
+
+ * Being in the 'next' branch is not a guarantee for a topic to
+   be included in the next feature release.  Being in the
+   'master' branch typically is.

+A merge of two topics may not textually conflict but still have
+conflict at the semantic level. A classic example is for one topic
+to rename an variable and all its uses, while another topic adds a
+new use of the variable under its old name. When these two topics
+are merged together, the reference to the variable newly added by
+the latter topic will still use the old name in the result.
+
+The Meta/Reintegrate script that is used by redo-jch and redo-pu
+scripts implements a crude but usable way to work this issue around.
+When the script merges branch $X, it checks if "refs/merge-fix/$X"
+exists, and if so, the effect of it is squashed into the result of
+the mechanical merge.  In other words,
+
+     $ echo $X | Meta/Reintegrate
+
+is roughly equivalent to this sequence:
+
+     $ git merge --rerere-autoupdate $X
+     $ git commit
+     $ git cherry-pick -n refs/merge-fix/$X
+     $ git commit --amend
+
+The goal of this "prepare a merge-fix" step is to come up with a
+commit that can be squashed into a result of mechanical merge to
+correct semantic conflicts.
+
+After finding that the result of merging branch "ai/topic" to an
+integration branch had such a semantic conflict, say pu~4, check the
+problematic merge out on a detached HEAD, edit the working tree to
+fix the semantic conflict, and make a separate commit to record the
+fix-up:
+
+     $ git checkout pu~4
+     $ git show -s --pretty=%s ;# double check
+     Merge branch 'ai/topic' to pu
+     $ edit
+     $ git commit -m 'merge-fix/ai/topic' -a
+
+Then make a reference "refs/merge-fix/ai/topic" to point at this
+result:
+
+     $ git update-ref refs/merge-fix/ai/topic HEAD
+
+Then double check the result by asking Meta/Reintegrate to redo the
+merge:
+
+     $ git checkout pu~5 ;# the parent of the problem merge
+     $ echo ai/topic | Meta/Reintegrate
+     $ git diff pu~4
+
+This time, because you prepared refs/merge-fix/ai/topic, the
+resulting merge should have been tweaked to include the fix for the
+semantic conflict.
+
+Note that this assumes that the order in which conflicting branches
+are merged does not change.  If the reason why merging ai/topic
+branch needs this merge-fix is because another branch merged earlier
+to the integration branch changed the underlying assumption ai/topic
+branch made (e.g. ai/topic branch added a site to refer to a
+variable, while the other branch renamed that variable and adjusted
+existing use sites), and if you changed redo-jch (or redo-pu) script
+to merge ai/topic branch before the other branch, then the above
+merge-fix should not be applied while merging ai/topic, but should
+instead be applied while merging the other branch.  You would need
+to move the fix to apply to the other branch, perhaps like this:
+
+      $ mf=refs/merge-fix
+      $ git update-ref $mf/$the_other_branch $mf/ai/topic
+      $ git update-ref -d $mf/ai/topic

+Abstract: This is how-to documentation for people who want to add extension

+Content-type: text/asciidoc
+
+How to integrate new subcommands
+================================
+
+This is how-to documentation for people who want to add extension
+commands to Git.  It should be read alongside api-builtin.txt.
+
+Runtime environment
+-------------------
+
+Git subcommands are standalone executables that live in the Git exec
+path, normally /usr/lib/git-core.  The git executable itself is a
+thin wrapper that knows where the subcommands live, and runs them by
+passing command-line arguments to them.
+
+(If "git foo" is not found in the Git exec path, the wrapper
+will look in the rest of your $PATH for it.  Thus, it's possible
+to write local Git extensions that don't live in system space.)
+
+Implementation languages
+------------------------
+
+Most subcommands are written in C or shell.  A few are written in
+Perl.
+
+While we strongly encourage coding in portable C for portability,
+these specific scripting languages are also acceptable.  We won't
+accept more without a very strong technical case, as we don't want
+to broaden the Git suite's required dependencies.  Import utilities,
+surgical tools, remote helpers and other code at the edges of the
+Git suite are more lenient and we allow Python (and even Tcl/tk),
+but they should not be used for core functions.
+
+This may change in the future.  Especially Python is not allowed in
+core because we need better Python integration in the Git Windows
+installer before we can be confident people in that environment
+won't experience an unacceptably large loss of capability.
+
+C commands are normally written as single modules, named after the
+command, that link a collection of functions called libgit.  Thus,
+your command 'git-foo' would normally be implemented as a single
+"git-foo.c" (or "builtin/foo.c" if it is to be linked to the main
+binary); this organization makes it easy for people reading the code
+to find things.
+
+See the CodingGuidelines document for other guidance on what we consider
+good practice in C and shell, and api-builtin.txt for the support
+functions available to built-in commands written in C.
+
+What every extension command needs
+----------------------------------
+
+You must have a man page, written in asciidoc (this is what Git help
+followed by your subcommand name will display).  Be aware that there is
+a local asciidoc configuration and macros which you should use.  It's
+often helpful to start by cloning an existing page and replacing the
+text content.
+
+You must have a test, written to report in TAP (Test Anything Protocol).
+Tests are executables (usually shell scripts) that live in the 't'
+subdirectory of the tree.  Each test name begins with 't' and a sequence
+number that controls where in the test sequence it will be executed;
+conventionally the rest of the name stem is that of the command
+being tested.
+
+Read the file t/README to learn more about the conventions to be used
+in writing tests, and the test support library.
+
+Integrating a command
+---------------------
+
+Here are the things you need to do when you want to merge a new
+subcommand into the Git tree.
+
+1. Don't forget to sign off your patch!
+
+2. Append your command name to one of the variables BUILTIN_OBJS,
+EXTRA_PROGRAMS, SCRIPT_SH, SCRIPT_PERL or SCRIPT_PYTHON.
+
+3. Drop its test in the t directory.
+
+4. If your command is implemented in an interpreted language with a
+p-code intermediate form, make sure .gitignore in the main directory
+includes a pattern entry that ignores such files.  Python .pyc and
+.pyo files will already be covered.
+
+5. If your command has any dependency on a particular version of
+your language, document it in the INSTALL file.
+
+6. There is a file command-list.txt in the distribution main directory
+that categorizes commands by type, so they can be listed in appropriate
+subsections in the documentation's summary command list.  Add an entry
+for yours.  To understand the categories, look at git-commands.txt
+in the main directory.  If the new command is part of the typical Git
+workflow and you believe it common enough to be mentioned in 'git help',
+map this command to a common group in the column [common].
+
+7. Give the maintainer one paragraph to include in the RelNotes file
+to describe the new feature; a good place to do so is in the cover
+letter [PATCH 0/n].
+
+That's all there is to it.

+-----------------------------------------------------------
+
+So exactly *because* the SHA-1 hash is cryptographically secure, the hash
+itself doesn't actually tell you anything, in order to fix a corrupt
+object you basically have to find the "original source" for it.
+
+The easiest way to do that is almost always to have backups, and find the
+same object somewhere else. Backups really are a good idea, and Git makes
+it pretty easy (if nothing else, just clone the repository somewhere else,
+and make sure that you do *not* use a hard-linked clone, and preferably
+not the same disk/machine).
+
+But since you don't seem to have backups right now, the good news is that
+especially with a single blob being corrupt, these things *are* somewhat
+debuggable.
+
+First off, move the corrupt object away, and *save* it. The most common
+cause of corruption so far has been memory corruption, but even so, there
+are people who would be interested in seeing the corruption - but it's
+basically impossible to judge the corruption until we can also see the
+original object, so right now the corrupt object is useless, but it's very
+interesting for the future, in the hope that you can re-create a
+non-corrupt version.
+
+-----------------------------------------------------------
+So:
+
+> ib]$ mv .git/objects/4b/9458b3786228369c63936db65827de3cc06200 ../
+-----------------------------------------------------------
+
+This is the right thing to do, although it's usually best to save it under
+it's full SHA-1 name (you just dropped the "4b" from the result ;).
+
+Let's see what that tells us:
+
+-----------------------------------------------------------
+> ib]$ git-fsck --full
+> broken link from    tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8

+> missing blob 4b9458b3786228369c63936db65827de3cc06200
+-----------------------------------------------------------
+
+Ok, I removed the "dangling commit" messages, because they are just
+messages about the fact that you probably have rebased etc, so they're not
+at all interesting. But what remains is still very useful. In particular,
+we now know which tree points to it!
+
+Now you can do
+
+	git ls-tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8
+
+which will show something like
+
+	100644 blob 8d14531846b95bfa3564b58ccfb7913a034323b8    .gitignore
+	100644 blob ebf9bf84da0aab5ed944264a5db2a65fe3a3e883    .mailmap

+	100644 blob 1c7c229a092665b11cd46a25dbd40feeb31661d9    MAINTAINERS
+	...
+
+and you should now have a line that looks like
+
+	10064 blob 4b9458b3786228369c63936db65827de3cc06200	my-magic-file
+
+in the output. This already tells you a *lot* it tells you what file the
+corrupt blob came from!
+
+Now, it doesn't tell you quite enough, though: it doesn't tell what
+*version* of the file didn't get correctly written! You might be really
+lucky, and it may be the version that you already have checked out in your
+working tree, in which case fixing this problem is really simple, just do
+
+	git hash-object -w my-magic-file
+
+again, and if it outputs the missing SHA-1 (4b945..) you're now all done!
+
+But that's the really lucky case, so let's assume that it was some older
+version that was broken. How do you tell which version it was?
+
+The easiest way to do it is to do
+
+	git log --raw --all --full-history -- subdirectory/my-magic-file
+
+and that will show you the whole log for that file (please realize that
+the tree you had may not be the top-level tree, so you need to figure out
+which subdirectory it was in on your own), and because you're asking for
+raw output, you'll now get something like
+
+	commit abc
+	Author:

+of that file were! So now you can look at those ("oldsha" and "newsha"
+respectively), and hopefully you have done commits often, and can
+re-create the missing my-magic-file version by looking at those older and

+(Btw, you could have ignored the fsck, and started with doing a

+
+and just looked for the sha of the missing object (4b9458b..) in that

+Subject: pack corruption post-mortem
+Abstract: Recovering a corrupted object when no good copy is available.
+Content-type: text/asciidoc
+
+How to recover an object from scratch
+=====================================
+
+I was recently presented with a repository with a corrupted packfile,
+and was asked if the data was recoverable. This post-mortem describes
+the steps I took to investigate and fix the problem. I thought others
+might find the process interesting, and it might help somebody in the
+same situation.
+
+********************************
+Note: In this case, no good copy of the repository was available. For
+the much easier case where you can get the corrupted object from
+elsewhere, see link:recover-corrupted-blob-object.html[this howto].
+********************************
+
+I started with an fsck, which found a problem with exactly one object
+(I've used $pack and $obj below to keep the output readable, and also
+because I'll refer to them later):
+
+-----------
+    $ git fsck
+    error: $pack SHA1 checksum mismatch
+    error: index CRC mismatch for object $obj from $pack at offset 51653873
+    error: inflate: data stream error (incorrect data check)
+    error: cannot unpack $obj from $pack at offset 51653873
+-----------
+
+The pack checksum failing means a byte is munged somewhere, and it is
+presumably in the object mentioned (since both the index checksum and
+zlib were failing).
+
+Reading the zlib source code, I found that "incorrect data check" means
+that the adler-32 checksum at the end of the zlib data did not match the
+inflated data. So stepping the data through zlib would not help, as it
+did not fail until the very end, when we realize the CRC does not match.
+The problematic bytes could be anywhere in the object data.
+
+The first thing I did was pull the broken data out of the packfile. I
+needed to know how big the object was, which I found out with:
+
+------------
+    $ git show-index <$idx | cut -d' ' -f1 | sort -n | grep -A1 51653873
+    51653873
+    51664736
+------------
+
+Show-index gives us the list of objects and their offsets. We throw away
+everything but the offsets, and then sort them so that our interesting
+offset (which we got from the fsck output above) is followed immediately
+by the offset of the next object. Now we know that the object data is
+10863 bytes long, and we can grab it with:
+
+------------
+  dd if=$pack of=object bs=1 skip=51653873 count=10863
+------------
+
+I inspected a hexdump of the data, looking for any obvious bogosity
+(e.g., a 4K run of zeroes would be a good sign of filesystem
+corruption). But everything looked pretty reasonable.
+
+Note that the "object" file isn't fit for feeding straight to zlib; it
+has the git packed object header, which is variable-length. We want to
+strip that off so we can start playing with the zlib data directly. You
+can either work your way through it manually (the format is described in
+link:../technical/pack-format.html[Documentation/technical/pack-format.txt]),
+or you can walk through it in a debugger. I did the latter, creating a
+valid pack like:
+
+------------
+    # pack magic and version
+    printf 'PACK\0\0\0\2' >tmp.pack
+    # pack has one object
+    printf '\0\0\0\1' >>tmp.pack
+    # now add our object data
+    cat object >>tmp.pack
+    # and then append the pack trailer
+    /path/to/git.git/test-sha1 -b <tmp.pack >trailer
+    cat trailer >>tmp.pack
+------------
+
+and then running "git index-pack tmp.pack" in the debugger (stop at
+unpack_raw_entry). Doing this, I found that there were 3 bytes of header
+(and the header itself had a sane type and size). So I stripped those
+off with:
+
+------------
+    dd if=object of=zlib bs=1 skip=3
+------------
+
+I ran the result through zlib's inflate using a custom C program. And
+while it did report the error, I did get the right number of output
+bytes (i.e., it matched git's size header that we decoded above). But
+feeding the result back to "git hash-object" didn't produce the same
+sha1. So there were some wrong bytes, but I didn't know which. The file
+happened to be C source code, so I hoped I could notice something
+obviously wrong with it, but I didn't. I even got it to compile!
+
+I also tried comparing it to other versions of the same path in the
+repository, hoping that there would be some part of the diff that didn't
+make sense. Unfortunately, this happened to be the only revision of this
+particular file in the repository, so I had nothing to compare against.
+
+So I took a different approach. Working under the guess that the
+corruption was limited to a single byte, I wrote a program to munge each
+byte individually, and try inflating the result. Since the object was
+only 10K compressed, that worked out to about 2.5M attempts, which took
+a few minutes.
+
+The program I used is here:
+
+----------------------------------------------
+#include <stdio.h>
+#include <unistd.h>
+#include <string.h>
+#include <signal.h>
+#include <zlib.h>
+
+static int try_zlib(unsigned char *buf, int len)
+{
+	/* make this absurdly large so we don't have to loop */
+	static unsigned char out[1024*1024];
+	z_stream z;
+	int ret;
+
+	memset(&z, 0, sizeof(z));
+	inflateInit(&z);
+
+	z.next_in = buf;
+	z.avail_in = len;
+	z.next_out = out;
+	z.avail_out = sizeof(out);
+
+	ret = inflate(&z, 0);
+	inflateEnd(&z);
+	return ret >= 0;
+}
+
+/* eye candy */
+static int counter = 0;
+static void progress(int sig)
+{
+	fprintf(stderr, "\r%d", counter);
+	alarm(1);
+}
+
+int main(void)
+{
+	/* oversized so we can read the whole buffer in */
+	unsigned char buf[1024*1024];
+	int len;
+	unsigned i, j;
+
+	signal(SIGALRM, progress);
+	alarm(1);
+
+	len = read(0, buf, sizeof(buf));
+	for (i = 0; i < len; i++) {
+		unsigned char c = buf[i];
+		for (j = 0; j <= 0xff; j++) {
+			buf[i] = j;
+
+			counter++;
+			if (try_zlib(buf, len))
+				printf("i=%d, j=%x\n", i, j);
+		}
+		buf[i] = c;
+	}
+
+	alarm(0);
+	fprintf(stderr, "\n");
+	return 0;
+}
+----------------------------------------------
+
+I compiled and ran with:
+
+-------
+  gcc -Wall -Werror -O3 munge.c -o munge -lz
+  ./munge <zlib
+-------
+
+
+There were a few false positives early on (if you write "no data" in the
+zlib header, zlib thinks it's just fine :) ). But I got a hit about
+halfway through:
+
+-------
+  i=5642, j=c7
+-------
+
+I let it run to completion, and got a few more hits at the end (where it
+was munging the CRC to match our broken data). So there was a good
+chance this middle hit was the source of the problem.
+
+I confirmed by tweaking the byte in a hex editor, zlib inflating the
+result (no errors!), and then piping the output into "git hash-object",
+which reported the sha1 of the broken object. Success!
+
+I fixed the packfile itself with:
+
+-------
+  chmod +w $pack
+  printf '\xc7' | dd of=$pack bs=1 seek=51659518 conv=notrunc
+  chmod -w $pack
+-------
+
+The `\xc7` comes from the replacement byte our "munge" program found.
+The offset 51659518 is derived by taking the original object offset
+(51653873), adding the replacement offset found by "munge" (5642), and
+then adding back in the 3 bytes of git header we stripped.
+
+After that, "git fsck" ran clean.
+
+As for the corruption itself, I was lucky that it was indeed a single
+byte. In fact, it turned out to be a single bit. The byte 0xc7 was
+corrupted to 0xc5. So presumably it was caused by faulty hardware, or a
+cosmic ray.
+
+And the aborted attempt to look at the inflated output to see what was
+wrong? I could have looked forever and never found it. Here's the diff
+between what the corrupted data inflates to, versus the real data:
+
+--------------
+  -       cp = strtok (arg, "+");
+  +       cp = strtok (arg, ".");
+--------------
+
+It tweaked one byte and still ended up as valid, readable C that just
+happened to do something totally different! One takeaway is that on a
+less unlucky day, looking at the zlib output might have actually been
+helpful, as most random changes would actually break the C code.
+
+But more importantly, git's hashing and checksumming noticed a problem
+that easily could have gone undetected in another system. The result
+still compiled, but would have caused an interesting bug (that would
+have been blamed on some random commit).
+
+
+The adventure continues...
+--------------------------
+
+I ended up doing this again! Same entity, new hardware. The assumption
+at this point is that the old disk corrupted the packfile, and then the
+corruption was migrated to the new hardware (because it was done by
+rsync or similar, and no fsck was done at the time of migration).
+
+This time, the affected blob was over 20 megabytes, which was far too
+large to do a brute-force on. I followed the instructions above to
+create the `zlib` file. I then used the `inflate` program below to pull
+the corrupted data from that. Examining that output gave me a hint about
+where in the file the corruption was. But now I was working with the
+file itself, not the zlib contents. So knowing the sha1 of the object
+and the approximate area of the corruption, I used the `sha1-munge`
+program below to brute-force the correct byte.
+
+Here's the inflate program (it's essentially `gunzip` but without the
+`.gz` header processing):
+
+--------------------------
+#include <stdio.h>
+#include <string.h>
+#include <zlib.h>
+#include <stdlib.h>
+
+int main(int argc, char **argv)
+{
+	/*
+	 * oversized so we can read the whole buffer in;
+	 * this could actually be switched to streaming
+	 * to avoid any memory limitations
+	 */
+	static unsigned char buf[25 * 1024 * 1024];
+	static unsigned char out[25 * 1024 * 1024];
+	int len;
+	z_stream z;
+	int ret;
+
+	len = read(0, buf, sizeof(buf));
+	memset(&z, 0, sizeof(z));
+	inflateInit(&z);
+
+	z.next_in = buf;
+	z.avail_in = len;
+	z.next_out = out;
+	z.avail_out = sizeof(out);
+
+	ret = inflate(&z, 0);
+	if (ret != Z_OK && ret != Z_STREAM_END)
+		fprintf(stderr, "initial inflate failed (%d)\n", ret);
+
+	fprintf(stderr, "outputting %lu bytes", z.total_out);
+	fwrite(out, 1, z.total_out, stdout);
+	return 0;
+}
+--------------------------
+
+And here is the `sha1-munge` program:
+
+--------------------------
+#include <stdio.h>
+#include <unistd.h>
+#include <string.h>
+#include <signal.h>
+#include <openssl/sha.h>
+#include <stdlib.h>

+ recovering from such a premature merge and continuing development
+ after the offending branch is fixed.

+
+How to revert a faulty merge
+============================
+
+Alan <alan@clueserver.org> said:
+
+    I have a master branch.  We have a branch off of that that some
+    developers are doing work on.  They claim it is ready. We merge it
+    into the master branch.  It breaks something so we revert the merge.
+    They make changes to the code.  they get it to a point where they say
+    it is ok and we merge again.
+
+    When examined, we find that code changes made before the revert are
+    not in the master branch, but code changes after are in the master
+    branch.
+
+and asked for help recovering from this situation.
+
+The history immediately after the "revert of the merge" would look like
+this:
+
+ ---o---o---o---M---x---x---W
+	       /
+       ---A---B
+
+where A and B are on the side development that was not so good, M is the
+merge that brings these premature changes into the mainline, x are changes
+unrelated to what the side branch did and already made on the mainline,
+and W is the "revert of the merge M" (doesn't W look M upside down?).
+IOW, `"diff W^..W"` is similar to `"diff -R M^..M"`.
+
+Such a "revert" of a merge can be made with:
+
+    $ git revert -m 1 M
+
+After the developers of the side branch fix their mistakes, the history
+may look like this:
+
+ ---o---o---o---M---x---x---W---x
+	       /
+       ---A---B-------------------C---D
+
+where C and D are to fix what was broken in A and B, and you may already
+have some other changes on the mainline after W.
+
+If you merge the updated side branch (with D at its tip), none of the
+changes made in A or B will be in the result, because they were reverted
+by W.  That is what Alan saw.
+
+Linus explains the situation:
+
+    Reverting a regular commit just effectively undoes what that commit
+    did, and is fairly straightforward. But reverting a merge commit also
+    undoes the _data_ that the commit changed, but it does absolutely
+    nothing to the effects on _history_ that the merge had.
+
+    So the merge will still exist, and it will still be seen as joining
+    the two branches together, and future merges will see that merge as
+    the last shared state - and the revert that reverted the merge brought
+    in will not affect that at all.
+
+    So a "revert" undoes the data changes, but it's very much _not_ an
+    "undo" in the sense that it doesn't undo the effects of a commit on
+    the repository history.
+
+    So if you think of "revert" as "undo", then you're going to always
+    miss this part of reverts. Yes, it undoes the data, but no, it doesn't
+    undo history.
+
+In such a situation, you would want to first revert the previous revert,
+which would make the history look like this:
+
+ ---o---o---o---M---x---x---W---x---Y
+	       /
+       ---A---B-------------------C---D
+
+where Y is the revert of W.  Such a "revert of the revert" can be done
+with:
+
+    $ git revert W
+
+This history would (ignoring possible conflicts between what W and W..Y
+changed) be equivalent to not having W or Y at all in the history:
+
+ ---o---o---o---M---x---x-------x----
+	       /
+       ---A---B-------------------C---D
+
+and merging the side branch again will not have conflict arising from an
+earlier revert and revert of the revert.
+
+ ---o---o---o---M---x---x-------x-------*
+	       /                       /
+       ---A---B-------------------C---D
+
+Of course the changes made in C and D still can conflict with what was
+done by any of the x, but that is just a normal merge conflict.
+
+On the other hand, if the developers of the side branch discarded their
+faulty A and B, and redone the changes on top of the updated mainline
+after the revert, the history would have looked like this:
+
+ ---o---o---o---M---x---x---W---x---x
+	       /                 \
+       ---A---B                   A'--B'--C'
+
+If you reverted the revert in such a case as in the previous example:
+
+ ---o---o---o---M---x---x---W---x---x---Y---*
+	       /                 \         /
+       ---A---B                   A'--B'--C'
+
+where Y is the revert of W, A' and B' are rerolled A and B, and there may
+also be a further fix-up C' on the side branch.  `"diff Y^..Y"` is similar
+to `"diff -R W^..W"` (which in turn means it is similar to `"diff M^..M"`),
+and `"diff A'^..C'"` by definition would be similar but different from that,
+because it is a rerolled series of the earlier change.  There will be a
+lot of overlapping changes that result in conflicts.  So do not do "revert
+of revert" blindly without thinking..
+
+ ---o---o---o---M---x---x---W---x---x
+	       /                 \
+       ---A---B                   A'--B'--C'
+
+In the history with rebased side branch, W (and M) are behind the merge
+base of the updated branch and the tip of the mainline, and they should
+merge without the past faulty merge and its revert getting in the way.
+
+To recap, these are two very different scenarios, and they want two very
+different resolution strategies:
+
+ - If the faulty side branch was fixed by adding corrections on top, then
+   doing a revert of the previous revert would be the right thing to do.
+
+ - If the faulty side branch whose effects were discarded by an earlier
+   revert of a merge was rebuilt from scratch (i.e. rebasing and fixing,
+   as you seem to have interpreted), then re-merging the result without
+   doing anything else fancy would be the right thing to do.
+   (See the ADDENDUM below for how to rebuild a branch from scratch
+   without changing its original branching-off point.)
+
+However, there are things to keep in mind when reverting a merge (and
+reverting such a revert).
+
+For example, think about what reverting a merge (and then reverting the
+revert) does to bisectability. Ignore the fact that the revert of a revert
+is undoing it - just think of it as a "single commit that does a lot".
+Because that is what it does.
+
+When you have a problem you are chasing down, and you hit a "revert this
+merge", what you're hitting is essentially a single commit that contains
+all the changes (but obviously in reverse) of all the commits that got
+merged. So it's debugging hell, because now you don't have lots of small
+changes that you can try to pinpoint which _part_ of it changes.
+
+But does it all work? Sure it does. You can revert a merge, and from a
+purely technical angle, Git did it very naturally and had no real
+troubles. It just considered it a change from "state before merge" to
+"state after merge", and that was it. Nothing complicated, nothing odd,
+nothing really dangerous. Git will do it without even thinking about it.
+
+So from a technical angle, there's nothing wrong with reverting a merge,
+but from a workflow angle it's something that you generally should try to
+avoid.
+
+If at all possible, for example, if you find a problem that got merged
+into the main tree, rather than revert the merge, try _really_ hard to
+bisect the problem down into the branch you merged, and just fix it, or
+try to revert the individual commit that caused it.
+
+Yes, it's more complex, and no, it's not always going to work (sometimes
+the answer is: "oops, I really shouldn't have merged it, because it wasn't
+ready yet, and I really need to undo _all_ of the merge"). So then you
+really should revert the merge, but when you want to re-do the merge, you
+now need to do it by reverting the revert.
+
+ADDENDUM
+
+Sometimes you have to rewrite one of a topic branch's commits *and* you can't
+change the topic's branching-off point.  Consider the following situation:
+
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C
+
+where commit W reverted commit M because it turned out that commit B was wrong
+and needs to be rewritten, but you need the rewritten topic to still branch
+from commit P (perhaps P is a branching-off point for yet another branch, and
+you want be able to merge the topic into both branches).
+
+The natural thing to do in this case is to checkout the A-B-C branch and use
+"rebase -i P" to change commit B.  However this does not rewrite commit A,
+because "rebase -i" by default fast-forwards over any initial commits selected
+with the "pick" command.  So you end up with this:
+
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C   <-- old branch
+    \
+     B'---C'   <-- naively rewritten branch
+
+To merge A-B'-C' into the mainline branch you would still have to first revert
+commit W in order to pick up the changes in A, but then it's likely that the
+changes in B' will conflict with the original B changes re-introduced by the
+reversion of W.
+
+However, you can avoid these problems if you recreate the entire branch,
+including commit A:
+
+   A'---B'---C'  <-- completely rewritten branch
+  /
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C
+
+You can merge A'-B'-C' into the mainline branch without worrying about first
+reverting W.  Mainline's history would look like this:
+
+   A'---B'---C'------------------
+  /                              \
+ P---o---o---M---x---x---W---x---M2
+  \         /
+   A---B---C
+
+But if you don't actually need to change commit A, then you need some way to
+recreate it as a new commit with the same changes in it.  The rebase command's
+--no-ff option provides a way to do this:
+
+    $ git rebase [-i] --no-ff P
+
+The --no-ff option creates a new branch A'-B'-C' with all-new commits (all the
+SHA IDs will be different) even if in the interactive case you only actually
+modify commit B.  You can then merge this new branch directly into the mainline
+branch and be sure you'll get all of the branch's changes.
+
+You can also use --no-ff in cases where you just add extra commits to the topic
+to fix it up.  Let's revisit the situation discussed at the start of this howto:
+
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C----------------D---E   <-- fixed-up topic branch
+
+At this point, you can use --no-ff to recreate the topic branch:
+
+    $ git checkout E
+    $ git rebase --no-ff P
+
+yielding
+
+   A'---B'---C'------------D'---E'  <-- recreated topic branch
+  /
+ P---o---o---M---x---x---W---x
+  \         /
+   A---B---C----------------D---E
+
+You can merge the recreated branch into the mainline without reverting commit W,
+and mainline's history will look like this:
+
+   A'---B'---C'------------D'---E'
+  /                              \
+ P---o---o---M---x---x---W---x---M2
+  \         /

+How to use git-daemon
+=====================
+
+Git can be run in inetd mode and in stand alone mode. But all you want is
+let a coworker pull from you, and therefore need to set up a Git server
+real quick, right?
+
+Note that git-daemon is not really chatty at the moment, especially when
+things do not go according to plan (e.g. a socket could not be bound).
+
+Another word of warning: if you run
+
+	$ git ls-remote git://127.0.0.1/rule-the-world.git
+
+and you see a message like
+
+	fatal: The remote end hung up unexpectedly
+
+it only means that _something_ went wrong. To find out _what_ went wrong,
+you have to ask the server. (Git refuses to be more precise for your
+security only. Take off your shoes now. You have any coins in your pockets?
+Sorry, not allowed -- who knows what you planned to do with them?)
+
+With these two caveats, let's see an example:
+
+	$ git daemon --reuseaddr --verbose --base-path=/home/gitte/git \
+	  --export-all -- /home/gitte/git/rule-the-world.git
+
+(Of course, unless your user name is `gitte` _and_ your repository is in
+~/rule-the-world.git, you have to adjust the paths. If your repository is
+not bare, be aware that you have to type the path to the .git directory!)
+
+This invocation tries to reuse the address if it is already taken
+(this can save you some debugging, because otherwise killing and restarting
+git-daemon could just silently fail to bind to a socket).
+
+Also, it is (relatively) verbose when somebody actually connects to it.
+It also sets the base path, which means that all the projects which can be
+accessed using this daemon have to reside in or under that path.
+
+The option `--export-all` just means that you _don't_ have to create a
+file named `git-daemon-export-ok` in each exported repository. (Otherwise,
+git-daemon would complain loudly, and refuse to cooperate.)
+
+Last of all, the repository which should be exported is specified. It is
+a good practice to put the paths after a "--" separator.
+
+Now, test your daemon with
+
+	$ git ls-remote git://127.0.0.1/rule-the-world.git
+
+If this does not work, find out why, and submit a patch to this document.

+Cc: git@vger.kernel.org
+Subject: how to use git merge -s subtree?
+Abstract: In this article, Sean demonstrates how one can use the subtree merge
+ strategy.
+Content-type: text/asciidoc
+Message-ID: <BAYC1-PASMTP12374B54BA370A1E1C6E78AE4E0@CEZ.ICE>
+
+How to use the subtree merge strategy
+=====================================
+
+There are situations where you want to include contents in your project
+from an independently developed project. You can just pull from the
+other project as long as there are no conflicting paths.
+
+The problematic case is when there are conflicting files. Potential
+candidates are Makefiles and other standard filenames. You could merge
+these files but probably you do not want to.  A better solution for this
+problem can be to merge the project as its own subdirectory. This is not
+supported by the 'recursive' merge strategy, so just pulling won't work.
+
+What you want is the 'subtree' merge strategy, which helps you in such a
+situation.
+
+In this example, let's say you have the repository at `/path/to/B` (but
+it can be a URL as well, if you want). You want to merge the 'master'
+branch of that repository to the `dir-B` subdirectory in your current
+branch.
+
+Here is the command sequence you need:
+
+----------------
+$ git remote add -f Bproject /path/to/B <1>
+$ git merge -s ours --no-commit Bproject/master <2>
+$ git read-tree --prefix=dir-B/ -u Bproject/master <3>
+$ git commit -m "Merge B project as our subdirectory" <4>
+
+$ git pull -s subtree Bproject master <5>
+----------------
+<1> name the other project "Bproject", and fetch.
+<2> prepare for the later step to record the result as a merge.
+<3> read "master" branch of Bproject to the subdirectory "dir-B".
+<4> record the merge result.
+<5> maintain the result with subsequent merges using "subtree"
+
+The first four commands are used for the initial merge, while the last
+one is to merge updates from 'B project'.
+
+Comparing 'subtree' merge with submodules
+-----------------------------------------
+
+- The benefit of using subtree merge is that it requires less
+  administrative burden from the users of your repository. It works with
+  older (before Git v1.5.2) clients and you have the code right after
+  clone.
+
+- However if you use submodules then you can choose not to transfer the
+  submodule objects. This may be a problem with the subtree merge.
+
+- Also, in case you make changes to the other project, it is easier to
+  submit changes if you just use submodules.
+
+Additional tips
+---------------
+
+- If you made changes to the other project in your repository, they may
+  want to merge from your project. This is possible using subtree -- it
+  can shift up the paths in your tree and then they can merge only the
+  relevant parts of your tree.
+
+- Please note that if the other project merges from you, then it will
+  connect its history to yours, which can be something they don't want
+  to.

+Subject: Using signed tag in pull requests
+Abstract: Beginning v1.7.9, a contributor can push a signed tag to her
+ publishing repository and ask her integrator to pull it. This assures the
+ integrator that the pulled history is authentic and allows others to
+ later validate it.
+Content-type: text/asciidoc
+
+How to use a signed tag in pull requests
+========================================
+
+A typical distributed workflow using Git is for a contributor to fork a
+project, build on it, publish the result to her public repository, and ask
+the "upstream" person (often the owner of the project where she forked
+from) to pull from her public repository. Requesting such a "pull" is made
+easy by the `git request-pull` command.
+
+Earlier, a typical pull request may have started like this:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the Git repository at:
+
+   example.com:/git/froboz.git for-xyzzy
+------------
+
+followed by a shortlog of the changes and a diffstat.
+
+The request was for a branch name (e.g. `for-xyzzy`) in the public
+repository of the contributor, and even though it stated where the
+contributor forked her work from, the message did not say anything about
+the commit to expect at the tip of the for-xyzzy branch. If the site that
+hosts the public repository of the contributor cannot be fully trusted, it
+was unnecessarily hard to make sure what was pulled by the integrator was
+genuinely what the contributor had produced for the project. Also there
+was no easy way for third-party auditors to later verify the resulting
+history.
+
+Starting from Git release v1.7.9, a contributor can add a signed tag to
+the commit at the tip of the history and ask the integrator to pull that
+signed tag. When the integrator runs `git pull`, the signed tag is
+automatically verified to assure that the history is not tampered with.
+In addition, the resulting merge commit records the content of the signed
+tag, so that other people can verify that the branch merged by the
+integrator was signed by the contributor, without fetching the signed tag
+used to validate the pull request separately and keeping it in the refs
+namespace.
+
+This document describes the workflow between the contributor and the
+integrator, using Git v1.7.9 or later.
+
+
+A contributor or a lieutenant
+-----------------------------
+
+After preparing her work to be pulled, the contributor uses `git tag -s`
+to create a signed tag:
+
+------------
+ $ git checkout work
+ $ ... "git pull" from sublieutenants, "git commit" your own work ...
+ $ git tag -s -m "Completed frotz feature" frotz-for-xyzzy work
+------------
+
+Note that this example uses the `-m` option to create a signed tag with
+just a one-liner message, but this is for illustration purposes only. It
+is advisable to compose a well-written explanation of what the topic does
+to justify why it is worthwhile for the integrator to pull it, as this
+message will eventually become part of the final history after the
+integrator responds to the pull request (as we will see later).
+
+Then she pushes the tag out to her public repository:
+
+------------
+ $ git push example.com:/git/froboz.git/ +frotz-for-xyzzy
+------------
+
+There is no need to push the `work` branch or anything else.
+
+Note that the above command line used a plus sign at the beginning of
+`+frotz-for-xyzzy` to allow forcing the update of a tag, as the same
+contributor may want to reuse a signed tag with the same name after the
+previous pull request has already been responded to.
+
+The contributor then prepares a message to request a "pull":
+
+------------
+ $ git request-pull v3.2 example.com:/git/froboz.git/ frotz-for-xyzzy >msg.txt
+------------
+
+The arguments are:
+
+. the version of the integrator's commit the contributor based her work on;
+. the URL of the repository, to which the contributor has pushed what she
+  wants to get pulled; and
+. the name of the tag the contributor wants to get pulled (earlier, she could
+  write only a branch name here).
+
+The resulting msg.txt file begins like so:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the Git repository at:
+
+   example.com:/git/froboz.git tags/frotz-for-xyzzy
+
+ for you to fetch changes up to 703f05ad5835c...:
+
+   Add tests and documentation for frotz (2011-12-02 10:02:52 -0800)
+
+ -----------------------------------------------
+ Completed frotz feature
+ -----------------------------------------------
+------------
+
+followed by a shortlog of the changes and a diffstat.  Comparing this with
+the earlier illustration of the output from the traditional `git request-pull`
+command, the reader should notice that:
+
+. The tip commit to expect is shown to the integrator; and
+. The signed tag message is shown prominently between the dashed lines
+  before the shortlog.
+
+The latter is why the contributor would want to justify why pulling her
+work is worthwhile when creating the signed tag.  The contributor then
+opens her favorite MUA, reads msg.txt, edits and sends it to her upstream
+integrator.
+
+
+Integrator
+----------
+
+After receiving such a pull request message, the integrator fetches and
+integrates the tag named in the request, with:
+
+------------
+ $ git pull example.com:/git/froboz.git/ tags/frotz-for-xyzzy
+------------
+
+This operation will always open an editor to allow the integrator to fine
+tune the commit log message when merging a signed tag.  Also, pulling a
+signed tag will always create a merge commit even when the integrator does
+not have any new commit since the contributor's work forked (i.e. 'fast
+forward'), so that the integrator can properly explain what the merge is
+about and why it was made.
+
+In the editor, the integrator will see something like this:
+
+------------
+ Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/
+
+ Completed frotz feature
+ # gpg: Signature made Fri 02 Dec 2011 10:03:01 AM PST using RSA key ID 96AFE6CB
+ # gpg: Good signature from "Con Tributor <nitfol@example.com>"
+------------
+
+Notice that the message recorded in the signed tag "Completed frotz
+feature" appears here, and again that is why it is important for the
+contributor to explain her work well when creating the signed tag.
+
+As usual, the lines commented with `#` are stripped out. The resulting
+commit records the signed tag used for this validation in a hidden field
+so that it can later be used by others to audit the history. There is no
+need for the integrator to keep a separate copy of the tag in his
+repository (i.e. `git tag -l` won't list the `frotz-for-xyzzy` tag in the
+above example), and there is no need to publish the tag to his public
+repository, either.
+
+After the integrator responds to the pull request and her work becomes
+part of the permanent history, the contributor can remove the tag from
+her public repository, if she chooses, in order to keep the tag namespace
+of her public repository clean, with:
+
+------------
+ $ git push example.com:/git/froboz.git :frotz-for-xyzzy
+------------
+
+
+Auditors
+--------
+
+The `--show-signature` option can be given to `git log` or `git show` and
+shows the verification status of the embedded signed tag in merge commits
+created when the integrator responded to a pull request of a signed tag.
+
+A typical output from `git show --show-signature` may look like this:
+
+------------
+ $ git show --show-signature
+ commit 02306ef6a3498a39118aef9df7975bdb50091585
+ merged tag 'frotz-for-xyzzy'
+ gpg: Signature made Fri 06 Jan 2012 12:41:49 PM PST using RSA key ID 96AFE6CB
+ gpg: Good signature from "Con Tributor <nitfol@example.com>"
+ Merge: 406da78 703f05a
+ Author: Inte Grator <xyzzy@example.com>
+ Date:   Tue Jan 17 13:49:41 2012 -0800
+
+     Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/
+
+     Completed frotz feature
+
+     * tag 'frotz-for-xyzzy' (100 commits)
+       Add tests and documentation for frotz
+       ...
+------------
+
+There is no need for the auditor to explicitly fetch the contributor's
+signature, or to even be aware of what tag(s) the contributor and integrator
+used to communicate the signature.  All the required information is recorded
+as part of the merge commit.

-From: tony.luck@intel.com
-Subject: Some tutorial text (was git/cogito workshop/bof at linuxconf au?)
-Abstract: In this article, Tony Luck discusses how he uses GIT
- as a Linux subsystem maintainer.
-
-Here's something that I've been putting together on how I'm using
-GIT as a Linux subsystem maintainer.
-
--Tony
-
-Last updated w.r.t. GIT 1.1
-
-Linux subsystem maintenance using GIT
--------------------------------------
-
-My requirements here are to be able to create two public trees:
-
-1) A "test" tree into which patches are initially placed so that they
-can get some exposure when integrated with other ongoing development.
-This tree is available to Andrew for pulling into -mm whenever he wants.
-
-2) A "release" tree into which tested patches are moved for final
-sanity checking, and as a vehicle to send them upstream to Linus
-(by sending him a "please pull" request.)
-
-Note that the period of time that each patch spends in the "test" tree
-is dependent on the complexity of the change.  Since GIT does not support
-cherry picking, it is not practical to simply apply all patches to the
-test tree and then pull to the release tree as that would leave trivial
-patches blocked in the test tree waiting for complex changes to accumulate
-enough test time to graduate.
-
-Back in the BitKeeper days I achieved this by creating small forests of
-temporary trees, one tree for each logical grouping of patches, and then
-pulling changes from these trees first to the test tree, and then to the
-release tree.  At first I replicated this in GIT, but then I realised
-that I could so this far more efficiently using branches inside a single
-GIT repository.
-
-So here is the step-by-step guide how this all works for me.
-
-First create your work tree by cloning Linus's public tree:
-
- $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git work
-
-Change directory into the cloned tree you just created
-
- $ cd work
-
-Set up a remotes file so that you can fetch the latest from Linus' master
-branch into a local branch named "linus":
-
- $ cat > .git/remotes/linus
- URL: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
- Pull: master:linus
- ^D
-
-and create the linus branch:
-
- $ git branch linus
-
-The "linus" branch will be used to track the upstream kernel.  To update it,
-you simply run:
-
- $ git fetch linus
-
-you can do this frequently (and it should be safe to do so with pending
-work in your tree, but perhaps not if you are in mid-merge).
-
-If you need to keep track of other public trees, you can add remote branches
-for them too:
-
- $ git branch another
- $ cat > .git/remotes/another
- URL: ... insert URL here ...
- Pull: name-of-branch-in-this-remote-tree:another
- ^D
-
-and run:
-
- $ git fetch another
-
-Now create the branches in which you are going to work, these start
-out at the current tip of the linus branch.
-
- $ git branch test linus
- $ git branch release linus
-
-These can be easily kept up to date by merging from the "linus" branch:
-
- $ git checkout test && git merge "Auto-update from upstream" test linus
- $ git checkout release && git merge "Auto-update from upstream" release linus
-
-Important note!  If you have any local changes in these branches, then
-this merge will create a commit object in the history (with no local
-changes git will simply do a "Fast forward" merge).  Many people dislike
-the "noise" that this creates in the Linux history, so you should avoid
-doing this capriciously in the "release" branch, as these noisy commits
-will become part of the permanent history when you ask Linus to pull
-from the release branch.
-
-Set up so that you can push upstream to your public tree (you need to
-log-in to the remote system and create an empty tree there before the
-first push).
-
- $ cat > .git/remotes/mytree
- URL: master.kernel.org:/pub/scm/linux/kernel/git/aegl/linux-2.6.git
- Push: release
- Push: test
- ^D
-
-and the push both the test and release trees using:
-
- $ git push mytree
-
-or push just one of the test and release branches using:
-
- $ git push mytree test
-or
- $ git push mytree release
-
-Now to apply some patches from the community.  Think of a short
-snappy name for a branch to hold this patch (or related group of
-patches), and create a new branch from the current tip of the
-linus branch:
-
- $ git checkout -b speed-up-spinlocks linus
-
-Now you apply the patch(es), run some tests, and commit the change(s).  If
-the patch is a multi-part series, then you should apply each as a separate
-commit to this branch.
-
- $ ... patch ... test  ... commit [ ... patch ... test ... commit ]*
-
-When you are happy with the state of this change, you can pull it into the
-"test" branch in preparation to make it public:
-
- $ git checkout test && git merge "Pull speed-up-spinlock changes" test speed-up-spinlocks
-
-It is unlikely that you would have any conflicts here ... but you might if you
-spent a while on this step and had also pulled new versions from upstream.
-
-Some time later when enough time has passed and testing done, you can pull the
-same branch into the "release" tree ready to go upstream.  This is where you
-see the value of keeping each patch (or patch series) in its own branch.  It
-means that the patches can be moved into the "release" tree in any order.
-
- $ git checkout release && git merge "Pull speed-up-spinlock changes" release speed-up-spinlocks
-
-After a while, you will have a number of branches, and despite the
-well chosen names you picked for each of them, you may forget what
-they are for, or what status they are in.  To get a reminder of what
-changes are in a specific branch, use:
-
- $ git-whatchanged branchname ^linus | git-shortlog
-
-To see whether it has already been merged into the test or release branches
-use:
-
- $ git-rev-list branchname ^test
-or
- $ git-rev-list branchname ^release
-
-[If this branch has not yet been merged you will see a set of SHA1 values
-for the commits, if it has been merged, then there will be no output]
-
-Once a patch completes the great cycle (moving from test to release, then
-pulled by Linus, and finally coming back into your local "linus" branch)
-the branch for this change is no longer needed.  You detect this when the
-output from:
-
- $ git-rev-list branchname ^linus
-
-is empty.  At this point the branch can be deleted:
-
- $ git branch -d branchname
-
-Some changes are so trivial that it is not necessary to create a separate
-branch and then merge into each of the test and release branches.  For
-these changes, just apply directly to the "release" branch, and then
-merge that into the "test" branch.
-
-To create diffstat and shortlog summaries of changes to include in a "please
-pull" request to Linus you can use:
-
- $ git-whatchanged -p release ^linus | diffstat -p1
-and
- $ git-whatchanged release ^linus | git-shortlog
-
-
-Here are some of the scripts that I use to simplify all this even further.

+
+In the simple form, each line in the file consists of the canonical

+--
+	Proper Name <commit@email.xx>

+The more complex forms are:

+--
+	Proper Name <proper@email.xx> <commit@email.xx>

+--
+which allows mailmap to replace both the name and the email of a

+would look like:
+
+------------
+Jane Doe         <jane@desktop.(none)>
+Joe R. Developer <joe@example.com>
+------------
+
+Note how there is no need for an entry for `<jane@laptop.(none)>`, because the
+real name of that author is already correct.

+Example 2: Your repository contains commits from the following

+nick2 <bugs@company.xx>
+nick2 <nick2@company.xx>
+santa <me@company.xx>

+merge.conflictStyle::
+	Specify the style in which conflicted hunks are written out to
+	working tree files upon merge.  The default is "merge", which
+	shows a `<<<<<<<` conflict marker, changes made by one side,
+	a `=======` marker, changes made by the other side, and then
+	a `>>>>>>>` marker.  An alternate style, "diff3", adds a `|||||||`
+	marker and the original text before the `=======` marker.

+merge.defaultToUpstream::
+	If merge is called without any commit argument, merge the upstream
+	branches configured for the current branch by using their last
+	observed values stored in their remote-tracking branches.
+	The values of the `branch.<current branch>.merge` that name the
+	branches at the remote named by `branch.<current branch>.remote`
+	are consulted, and then they are mapped via `remote.<remote>.fetch`

+
+merge.ff::
+	By default, Git does not create an extra merge commit when merging
+	a commit that is a descendant of the current commit. Instead, the
+	tip of the current branch is fast-forwarded. When set to `false`,
+	this variable tells Git to create an extra merge commit in such
+	a case (equivalent to giving the `--no-ff` option from the command

+
+merge.renormalize::
+	Tell Git that canonical representation of files in the
+	repository has changed over time (e.g. earlier commits record
+	text files with CRLF line endings, but recent ones use LF line
+	endings).  In such a repository, Git can convert the data
+	recorded in commits to a canonical form before performing a
+	merge to reduce unnecessary conflicts.  For more information,
+	see section "Merging branches with differing checkin/checkout
+	attributes" in linkgit:gitattributes[5].
+
+merge.stat::
+	Whether to print the diffstat between ORIG_HEAD and the merge result

+merge.tool::
+	Controls which merge tool is used by linkgit:git-mergetool[1].

+merge.verbosity::
+	Controls the amount of output shown by the recursive merge

 MERGE STRATEGIES
 ----------------
 
+The merge mechanism (`git merge` and `git pull` commands) allows the
+backend 'merge strategies' to be chosen with `-s` option.  Some strategies
+can also take their own options, which can be passed by giving `-X<option>`
+arguments to `git merge` and/or `git pull`.

++
+The 'recursive' strategy can take the following options:
+
+ours;;
+	This option forces conflicting hunks to be auto-resolved cleanly by
+	favoring 'our' version.  Changes from the other tree that do not
+	conflict with our side are reflected to the merge result.
+	For a binary file, the entire contents are taken from our side.
++

+even look at what the other tree contains at all.  It discards everything
+the other tree did, declaring 'our' history contains all that happened in it.
+
+theirs;;
+	This is the opposite of 'ours'.
+
+patience;;
+	With this option, 'merge-recursive' spends a little extra time
+	to avoid mismerges that sometimes occur due to unimportant
+	matching lines (e.g., braces from distinct functions).  Use
+	this when the branches to be merged have diverged wildly.
+	See also linkgit:git-diff[1] `--patience`.

+diff-algorithm=[patience|minimal|histogram|myers];;
+	Tells 'merge-recursive' to use a different diff algorithm, which
+	can help avoid mismerges that occur due to unimportant matching
+	lines (such as braces from distinct functions).  See also
+	linkgit:git-diff[1] `--diff-algorithm`.
+
+ignore-space-change;;
+ignore-all-space;;
+ignore-space-at-eol;;
+	Treats lines with the indicated type of whitespace change as
+	unchanged for the sake of a three-way merge.  Whitespace
+	changes mixed with other changes to a line are not ignored.
+	See also linkgit:git-diff[1] `-b`, `-w`, and
+	`--ignore-space-at-eol`.
++
+* If 'their' version only introduces whitespace changes to a line,
+  'our' version is used;
+* If 'our' version introduces whitespace changes but 'their'
+  version includes a substantial change, 'their' version is used;
+* Otherwise, the merge proceeds in the usual way.
+
+renormalize;;
+	This runs a virtual check-out and check-in of all three stages
+	of a file when resolving a three-way merge.  This option is
+	meant to be used when merging branches with different clean
+	filters or end-of-line normalization rules.  See "Merging
+	branches with differing checkin/checkout attributes" in
+	linkgit:gitattributes[5] for details.
+
+no-renormalize;;
+	Disables the `renormalize` option.  This overrides the
+	`merge.renormalize` configuration variable.

+rename-threshold=<n>;;
+	Controls the similarity threshold used for rename detection.
+	See also linkgit:git-diff[1] `-M`.
+
+subtree[=<path>];;
+	This option is a more advanced form of 'subtree' strategy, where

+	the 'recursive' merge strategy.
+
+subtree::
+	This is a modified recursive strategy. When merging trees A and

+	match the tree structure of A, instead of reading the trees at
+	the same level. This adjustment is also done to the common
+	ancestor tree.
+
+With the strategies that use 3-way merge (including the default, 'recursive'),
+if a change is made on both branches, but later reverted on one of the
+branches, that change will be present in the merged result; some people find
+this behavior confusing.  It occurs because only the heads and the merge base
+are considered when performing a merge, not the individual commits.  The merge
+algorithm therefore considers the reverted change as no change at all, and
+substitutes the changed version instead.

+The 'tformat:' format works exactly like 'format:', except that it

+This means that the final entry of a single-line format will be properly
+terminated with a new line, just as the "oneline" format does.
+For example:
++
+---------------------
+$ git log -2 --pretty=format:%h 4da45bef \
+  | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
+4da45be
+7134973 -- NO NEWLINE
+
+$ git log -2 --pretty=tformat:%h 4da45bef \
+  | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
+4da45be
+7134973
+---------------------
++
+In addition, any unrecognized string that has a `%` in it is interpreted
+as if it has `tformat:` in front of it.  For example, these two are
+equivalent:
++
+---------------------
+$ git log -2 --pretty=tformat:%h 4da45bef

+--format=<format>::
+
+	Pretty-print the contents of the commit logs in a given format,
+	where '<format>' can be one of 'oneline', 'short', 'medium',
+	'full', 'fuller', 'email', 'raw', 'format:<string>'
+	and 'tformat:<string>'.  When '<format>' is none of the above,
+	and has '%placeholder' in it, it acts as if
+	'--pretty=tformat:<format>' were given.
++
+See the "PRETTY FORMATS" section for some additional details for each
+format.  When '=<format>' part is omitted, it defaults to 'medium'.
++
+Note: you can specify the default pretty format in the repository
+configuration (see linkgit:git-config[1]).
+
+--abbrev-commit::
+	Instead of showing the full 40-byte hexadecimal commit object
+	name, show only a partial prefix.  Non default number of
+	digits can be specified with "--abbrev=<n>" (which also modifies
+	diff output, if it is displayed).
++
+This should make "--pretty=oneline" a whole lot more readable for
+people using 80-column terminals.
+
+--no-abbrev-commit::
+	Show the full 40-byte hexadecimal commit object name. This negates
+	`--abbrev-commit` and those options which imply it such as
+	"--oneline". It also overrides the 'log.abbrevCommit' variable.
+
+--oneline::
+	This is a shorthand for "--pretty=oneline --abbrev-commit"
+	used together.
+
+--encoding=<encoding>::
+	The commit objects record the encoding used for the log message
+	in their encoding header; this option can be used to tell the
+	command to re-code the commit log message in the encoding
+	preferred by the user.  For non plumbing commands this
+	defaults to UTF-8. Note that if an object claims to be encoded
+	in `X` and we are outputting in `X`, we will output the object
+	verbatim; this means that invalid sequences in the original
+	commit may be copied to the output.
+
+ifndef::git-rev-list[]
+--notes[=<ref>]::
+	Show the notes (see linkgit:git-notes[1]) that annotate the
+	commit, when showing the commit log message.  This is the default
+	for `git log`, `git show` and `git whatchanged` commands when
+	there is no `--pretty`, `--format`, or `--oneline` option given
+	on the command line.
++
+By default, the notes shown are from the notes refs listed in the
+'core.notesRef' and 'notes.displayRef' variables (or corresponding
+environment overrides). See linkgit:git-config[1] for more details.
++
+With an optional '<ref>' argument, show this notes ref instead of the
+default notes ref(s). The ref is taken to be in `refs/notes/` if it
+is not qualified.
++
+Multiple --notes options can be combined to control which notes are
+being displayed. Examples: "--notes=foo" will show only notes from
+"refs/notes/foo"; "--notes=foo --notes" will show both notes from
+"refs/notes/foo" and from the default notes ref(s).
+
+--no-notes::
+	Do not show notes. This negates the above `--notes` option, by
+	resetting the list of notes refs from which notes are shown.
+	Options are parsed in the order given on the command line, so e.g.
+	"--notes --notes=foo --no-notes --notes=bar" will only show notes
+	from "refs/notes/bar".
+
+--show-notes[=<ref>]::
+--[no-]standard-notes::
+	These options are deprecated. Use the above --notes/--no-notes
+	options instead.
+endif::git-rev-list[]
+
+--show-signature::
+	Check the validity of a signed commit object by passing the signature
+	to `gpg --verify` and show the output.

-git repository layout
-=====================
-
-You may find these things in your git repository (`.git`
-directory for a repository associated with your working tree, or
-`'project'.git` directory for a public 'bare' repository).
-
-objects::
-	Object store associated with this repository.  Usually
-	an object store is self sufficient (i.e. all the objects
-	that are referred to by an object found in it are also
-	found in it), but there are couple of ways to violate
-	it.
-+
-. You could populate the repository by running a commit walker
-without `-a` option.  Depending on which options are given, you
-could have only commit objects without associated blobs and
-trees this way, for example.  A repository with this kind of
-incomplete object store is not suitable to be published to the
-outside world but sometimes useful for private repository.
-. You also could have an incomplete but locally usable repository
-by cloning shallowly.  See gitlink:git-clone[1].
-. You can be using `objects/info/alternates` mechanism, or
-`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanism to 'borrow'
-objects from other object stores.  A repository with this kind
-of incomplete object store is not suitable to be published for
-use with dumb transports but otherwise is OK as long as
-`objects/info/alternates` points at the right object stores
-it borrows from.
-
-objects/[0-9a-f][0-9a-f]::
-	Traditionally, each object is stored in its own file.
-	They are split into 256 subdirectories using the first
-	two letters from its object name to keep the number of
-	directory entries `objects` directory itself needs to
-	hold.  Objects found here are often called 'unpacked'
-	(or 'loose') objects.
-
-objects/pack::
-	Packs (files that store many object in compressed form,
-	along with index files to allow them to be randomly
-	accessed) are found in this directory.
-
-objects/info::
-	Additional information about the object store is
-	recorded in this directory.
-
-objects/info/packs::
-	This file is to help dumb transports discover what packs
-	are available in this object store.  Whenever a pack is
-	added or removed, `git update-server-info` should be run
-	to keep this file up-to-date if the repository is
-	published for dumb transports.  `git repack` does this
-	by default.
-
-objects/info/alternates::
-	This file records paths to alternate object stores that
-	this object store borrows objects from, one pathname per
-	line. Note that not only native Git tools use it locally,
-	but the HTTP fetcher also tries to use it remotely; this
-	will usually work if you have relative paths (relative
-	to the object database, not to the repository!) in your
-	alternates file, but it will not work if you use absolute
-	paths unless the absolute path in filesystem and web URL
-	is the same. See also 'objects/info/http-alternates'.
-
-objects/info/http-alternates::
-	This file records URLs to alternate object stores that
-	this object store borrows objects from, to be used when
-	the repository is fetched over HTTP.
-
-refs::
-	References are stored in subdirectories of this
-	directory.  The `git prune` command knows to keep
-	objects reachable from refs found in this directory and
-	its subdirectories.
-
-refs/heads/`name`::
-	records tip-of-the-tree commit objects of branch `name`
-
-refs/tags/`name`::
-	records any object name (not necessarily a commit
-	object, or a tag object that points at a commit object).
-
-refs/remotes/`name`::
-	records tip-of-the-tree commit objects of branches copied
-	from a remote repository.
-
-packed-refs::
-	records the same information as refs/heads/, refs/tags/,
-	and friends record in a more efficient way.  See
-	gitlink:git-pack-refs[1].
-
-HEAD::
-	A symref (see glossary) to the `refs/heads/` namespace
-	describing the currently active branch.  It does not mean
-	much if the repository is not associated with any working tree
-	(i.e. a 'bare' repository), but a valid git repository
-	*must* have the HEAD file; some porcelains may use it to
-	guess the designated "default" branch of the repository
-	(usually 'master').  It is legal if the named branch
-	'name' does not (yet) exist.  In some legacy setups, it is
-	a symbolic link instead of a symref that points at the current
-	branch.
-+
-HEAD can also record a specific commit directly, instead of
-being a symref to point at the current branch.  Such a state
-is often called 'detached HEAD', and almost all commands work
-identically as normal.  See gitlink:git-checkout[1] for
-details.
-
-branches::
-	A slightly deprecated way to store shorthands to be used
-	to specify URL to `git fetch`, `git pull` and `git push`
-	commands is to store a file in `branches/'name'` and
-	give 'name' to these commands in place of 'repository'
-	argument.
-
-hooks::
-	Hooks are customization scripts used by various git
-	commands.  A handful of sample hooks are installed when
-	`git init` is run, but all of them are disabled by
-	default.  To enable, they need to be made executable.
-	Read link:hooks.html[hooks] for more details about
-	each hook.
-
-index::
-	The current index file for the repository.  It is
-	usually not found in a bare repository.
-
-info::
-	Additional information about the repository is recorded
-	in this directory.
-
-info/refs::
-	This file helps dumb transports discover what refs are
-	available in this repository.  If the repository is
-	published for dumb transports, this file should be
-	regenerated by `git update-server-info` every time a tag
-	or branch is created or modified.  This is normally done
-	from the `hooks/update` hook, which is run by the
-	`git-receive-pack` command when you `git push` into the
-	repository.
-
-info/grafts::
-	This file records fake commit ancestry information, to
-	pretend the set of parents a commit has is different
-	from how the commit was actually created.  One record
-	per line describes a commit and its fake parents by
-	listing their 40-byte hexadecimal object names separated
-	by a space and terminated by a newline.
-
-info/exclude::
-	This file, by convention among Porcelains, stores the
-	exclude pattern list. `.gitignore` is the per-directory
-	ignore file.  `git status`, `git add`, `git rm` and `git
-	clean` look at it but the core git commands do not look
-	at it.  See also: gitlink:git-ls-files[1] `--exclude-from`
-	and `--exclude-per-directory`.
-
-remotes::
-	Stores shorthands to be used to give URL and default
-	refnames to interact with remote repository to `git
-	fetch`, `git pull` and `git push` commands.
-
-logs::
-	Records of changes made to refs are stored in this
-	directory.  See the documentation on git-update-ref
-	for more information.
-
-logs/refs/heads/`name`::
-	Records all changes made to the branch tip named `name`.
-
-logs/refs/tags/`name`::
-	Records all changes made to the tag named `name`.
-
-shallow::
-	This is similar to `info/grafts` but is internally used
-	and maintained by shallow clone mechanism.  See `--depth`
-	option to gitlink:git-clone[1] and gitlink:git-fetch[1].

+Commit Limiting
+~~~~~~~~~~~~~~~
+
+Besides specifying a range of commits that should be listed using the
+special notations explained in the description, additional commit
+limiting may be applied.
+
+Using more options generally further limits the output (e.g.
+`--since=<date1>` limits to commits newer than `<date1>`, and using it
+with `--grep=<pattern>` further limits to commits whose log message
+has a line that matches `<pattern>`), unless otherwise noted.
+
+Note that these are applied before commit
+ordering and formatting options, such as `--reverse`.
+
+--
+
+-<number>::
+-n <number>::
+--max-count=<number>::
+	Limit the number of commits to output.
+
+--skip=<number>::
+	Skip 'number' commits before starting to show the commit output.
+
+--since=<date>::
+--after=<date>::
+	Show commits more recent than a specific date.
+
+--until=<date>::
+--before=<date>::
+	Show commits older than a specific date.
+
+ifdef::git-rev-list[]
+--max-age=<timestamp>::
+--min-age=<timestamp>::
+	Limit the commits output to specified time range.
+endif::git-rev-list[]
+
+--author=<pattern>::
+--committer=<pattern>::
+	Limit the commits output to ones with author/committer
+	header lines that match the specified pattern (regular
+	expression).  With more than one `--author=<pattern>`,
+	commits whose author matches any of the given patterns are
+	chosen (similarly for multiple `--committer=<pattern>`).
+
+--grep-reflog=<pattern>::
+	Limit the commits output to ones with reflog entries that
+	match the specified pattern (regular expression). With
+	more than one `--grep-reflog`, commits whose reflog message
+	matches any of the given patterns are chosen.  It is an
+	error to use this option unless `--walk-reflogs` is in use.
+
+--grep=<pattern>::
+	Limit the commits output to ones with log message that
+	matches the specified pattern (regular expression).  With
+	more than one `--grep=<pattern>`, commits whose message
+	matches any of the given patterns are chosen (but see
+	`--all-match`).
+ifndef::git-rev-list[]
++
+When `--show-notes` is in effect, the message from the notes is
+matched as if it were part of the log message.
+endif::git-rev-list[]
+
+--all-match::
+	Limit the commits output to ones that match all given `--grep`,
+	instead of ones that match at least one.
+
+--invert-grep::
+	Limit the commits output to ones with log message that do not
+	match the pattern specified with `--grep=<pattern>`.
+
+-i::
+--regexp-ignore-case::
+	Match the regular expression limiting patterns without regard to letter
+	case.
+
+--basic-regexp::
+	Consider the limiting patterns to be basic regular expressions;
+	this is the default.
+
+-E::
+--extended-regexp::
+	Consider the limiting patterns to be extended regular expressions
+	instead of the default basic regular expressions.
+
+-F::
+--fixed-strings::
+	Consider the limiting patterns to be fixed strings (don't interpret
+	pattern as a regular expression).
+
+--perl-regexp::
+	Consider the limiting patterns to be Perl-compatible regular expressions.
+	Requires libpcre to be compiled in.
+
+--remove-empty::
+	Stop when a given path disappears from the tree.
+
+--merges::
+	Print only merge commits. This is exactly the same as `--min-parents=2`.
+
+--no-merges::
+	Do not print commits with more than one parent. This is
+	exactly the same as `--max-parents=1`.
+
+--min-parents=<number>::
+--max-parents=<number>::
+--no-min-parents::
+--no-max-parents::
+	Show only commits which have at least (or at most) that many parent
+	commits. In particular, `--max-parents=1` is the same as `--no-merges`,
+	`--min-parents=2` is the same as `--merges`.  `--max-parents=0`
+	gives all root commits and `--min-parents=3` all octopus merges.
++
+`--no-min-parents` and `--no-max-parents` reset these limits (to no limit)
+again.  Equivalent forms are `--min-parents=0` (any commit has 0 or more
+parents) and `--max-parents=-1` (negative numbers denote no upper limit).
+
+--first-parent::
+	Follow only the first parent commit upon seeing a merge
+	commit.  This option can give a better overview when
+	viewing the evolution of a particular topic branch,
+	because merges into a topic branch tend to be only about
+	adjusting to updated upstream from time to time, and
+	this option allows you to ignore the individual commits
+	brought in to your history by such a merge. Cannot be
+	combined with --bisect.
+
+--not::
+	Reverses the meaning of the '{caret}' prefix (or lack thereof)
+	for all following revision specifiers, up to the next `--not`.
+
+--all::
+	Pretend as if all the refs in `refs/` are listed on the
+	command line as '<commit>'.
+
+--branches[=<pattern>]::
+	Pretend as if all the refs in `refs/heads` are listed
+	on the command line as '<commit>'. If '<pattern>' is given, limit
+	branches to ones matching given shell glob. If pattern lacks '?',
+	'{asterisk}', or '[', '/{asterisk}' at the end is implied.
+
+--tags[=<pattern>]::
+	Pretend as if all the refs in `refs/tags` are listed
+	on the command line as '<commit>'. If '<pattern>' is given, limit
+	tags to ones matching given shell glob. If pattern lacks '?', '{asterisk}',
+	or '[', '/{asterisk}' at the end is implied.
+
+--remotes[=<pattern>]::
+	Pretend as if all the refs in `refs/remotes` are listed
+	on the command line as '<commit>'. If '<pattern>' is given, limit
+	remote-tracking branches to ones matching given shell glob.
+	If pattern lacks '?', '{asterisk}', or '[', '/{asterisk}' at the end is implied.
+
+--glob=<glob-pattern>::
+	Pretend as if all the refs matching shell glob '<glob-pattern>'
+	are listed on the command line as '<commit>'. Leading 'refs/',
+	is automatically prepended if missing. If pattern lacks '?', '{asterisk}',
+	or '[', '/{asterisk}' at the end is implied.
+
+--exclude=<glob-pattern>::
+
+	Do not include refs matching '<glob-pattern>' that the next `--all`,
+	`--branches`, `--tags`, `--remotes`, or `--glob` would otherwise
+	consider. Repetitions of this option accumulate exclusion patterns
+	up to the next `--all`, `--branches`, `--tags`, `--remotes`, or
+	`--glob` option (other options or arguments do not clear
+	accumulated patterns).
++
+The patterns given should not begin with `refs/heads`, `refs/tags`, or
+`refs/remotes` when applied to `--branches`, `--tags`, or `--remotes`,
+respectively, and they must begin with `refs/` when applied to `--glob`
+or `--all`. If a trailing '/{asterisk}' is intended, it must be given
+explicitly.

+--reflog::
+	Pretend as if all objects mentioned by reflogs are listed on the
+	command line as `<commit>`.
+
+--ignore-missing::
+	Upon seeing an invalid object name in the input, pretend as if
+	the bad input was not given.
+
+ifndef::git-rev-list[]
+--bisect::
+	Pretend as if the bad bisection ref `refs/bisect/bad`
+	was listed and as if it was followed by `--not` and the good
+	bisection refs `refs/bisect/good-*` on the command
+	line. Cannot be combined with --first-parent.

+--stdin::
+	In addition to the '<commit>' listed on the command
+	line, read them from the standard input. If a '--' separator is

+
+ifdef::git-rev-list[]
+--quiet::
+	Don't print anything to standard output.  This form
+	is primarily meant to allow the caller to
+	test the exit status to see if a range of objects is fully
+	connected (or not).  It is faster than redirecting stdout
+	to `/dev/null` as the output does not have to be formatted.
+endif::git-rev-list[]
+
+--cherry-mark::
+	Like `--cherry-pick` (see below) but mark equivalent commits
+	with `=` rather than omitting them, and inequivalent ones with `+`.
+
+--cherry-pick::
+	Omit any commit that introduces the same change as
+	another commit on the ``other side'' when the set of
+	commits are limited with symmetric difference.
++
+For example, if you have two branches, `A` and `B`, a usual way
+to list all commits on only one side of them is with
+`--left-right` (see the example below in the description of
+the `--left-right` option). However, it shows the commits that were
+cherry-picked from the other branch (for example, ``3rd on b'' may be
+cherry-picked from branch A). With this option, such pairs of commits are
+excluded from the output.
+
+--left-only::
+--right-only::
+	List only commits on the respective side of a symmetric range,
+	i.e. only those which would be marked `<` resp. `>` by
+	`--left-right`.
++
+For example, `--cherry-pick --right-only A...B` omits those
+commits from `B` which are in `A` or are patch-equivalent to a commit in
+`A`. In other words, this lists the `+` commits from `git cherry A B`.
+More precisely, `--cherry-pick --right-only --no-merges` gives the exact
+list.
+
+--cherry::
+	A synonym for `--right-only --cherry-mark --no-merges`; useful to
+	limit the output to the commits on our side and mark those that
+	have been applied to the other side of a forked history with
+	`git log --cherry upstream...mybranch`, similar to
+	`git cherry upstream mybranch`.
+
+-g::
+--walk-reflogs::
+	Instead of walking the commit ancestry chain, walk
+	reflog entries from the most recent one to older ones.
+	When this option is used you cannot specify commits to
+	exclude (that is, '{caret}commit', 'commit1..commit2',
+	and 'commit1\...commit2' notations cannot be used).
++
+With `--pretty` format other than `oneline` (for obvious reasons),
+this causes the output to have two extra lines of information
+taken from the reflog.  By default, 'commit@\{Nth}' notation is
+used in the output.  When the starting commit is specified as
+'commit@\{now}', output also uses 'commit@\{timestamp}' notation
+instead.  Under `--pretty=oneline`, the commit message is
+prefixed with this information on the same line.
+This option cannot be combined with `--reverse`.
+See also linkgit:git-reflog[1].
+
+--merge::
+	After a failed merge, show refs that touch files having a
+	conflict and don't exist on all heads to merge.
+
+--boundary::
+	Output excluded boundary commits. Boundary commits are
+	prefixed with `-`.
+
+ifdef::git-rev-list[]
+--use-bitmap-index::
+
+	Try to speed up the traversal using the pack bitmap index (if
+	one is available). Note that when traversing with `--objects`,
+	trees and blobs will not have their associated path printed.

+
+History Simplification
+~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes you are only interested in parts of the history, for example the
+commits modifying a particular <path>. But there are two parts of
+'History Simplification', one part is selecting the commits and the other
+is how to do it, as there are various strategies to simplify the history.
+
+The following options select the commits to be shown:
+
+<paths>::
+	Commits modifying the given <paths> are selected.
+
+--simplify-by-decoration::
+	Commits that are referred by some branch or tag are selected.
+
+Note that extra commits can be shown to give a meaningful history.
+
+The following options affect the way the simplification is performed:
+
+Default mode::
+	Simplifies the history to the simplest history explaining the
+	final state of the tree. Simplest because it prunes some side
+	branches if the end result is the same (i.e. merging branches
+	with the same content)
+
+--full-history::
+	Same as the default mode, but does not prune some history.
+
+--dense::
+	Only the selected commits are shown, plus some to have a
+	meaningful history.
+
+--sparse::
+	All commits in the simplified history are shown.
+
+--simplify-merges::
+	Additional option to `--full-history` to remove some needless
+	merges from the resulting history, as there are no selected
+	commits contributing to this merge.
+
+--ancestry-path::
+	When given a range of commits to display (e.g. 'commit1..commit2'
+	or 'commit2 {caret}commit1'), only display commits that exist
+	directly on the ancestry chain between the 'commit1' and
+	'commit2', i.e. commits that are both descendants of 'commit1',
+	and ancestors of 'commit2'.
+
+A more detailed explanation follows.
+
+Suppose you specified `foo` as the <paths>.  We shall call commits
+that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
+filtered for `foo`, they look different and equal, respectively.)
+
+In the following, we will always refer to the same example history to
+illustrate the differences between simplification settings.  We assume
+that you are filtering for a file `foo` in this commit graph:
+-----------------------------------------------------------------------
+	  .-A---M---N---O---P---Q
+	 /     /   /   /   /   /
+	I     B   C   D   E   Y
+	 \   /   /   /   /   /
+	  `-------------'   X
+-----------------------------------------------------------------------
+The horizontal line of history A---Q is taken to be the first parent of
+each merge.  The commits are:
+
+* `I` is the initial commit, in which `foo` exists with contents
+  ``asdf'', and a file `quux` exists with contents ``quux''. Initial
+  commits are compared to an empty tree, so `I` is !TREESAME.
+
+* In `A`, `foo` contains just ``foo''.
+
+* `B` contains the same change as `A`.  Its merge `M` is trivial and
+  hence TREESAME to all parents.
+
+* `C` does not change `foo`, but its merge `N` changes it to ``foobar'',
+  so it is not TREESAME to any parent.
+
+* `D` sets `foo` to ``baz''. Its merge `O` combines the strings from
+  `N` and `D` to ``foobarbaz''; i.e., it is not TREESAME to any parent.
+
+* `E` changes `quux` to ``xyzzy'', and its merge `P` combines the
+  strings to ``quux xyzzy''. `P` is TREESAME to `O`, but not to `E`.
+
+* `X` is an independent root commit that added a new file `side`, and `Y`
+  modified it. `Y` is TREESAME to `X`. Its merge `Q` added `side` to `P`, and
+  `Q` is TREESAME to `P`, but not to `Y`.
+
+`rev-list` walks backwards through history, including or excluding
+commits based on whether `--full-history` and/or parent rewriting
+(via `--parents` or `--children`) are used. The following settings
+are available.
+
+Default mode::
+	Commits are included if they are not TREESAME to any parent
+	(though this can be changed, see `--sparse` below).  If the
+	commit was a merge, and it was TREESAME to one parent, follow
+	only that parent.  (Even if there are several TREESAME
+	parents, follow only one of them.)  Otherwise, follow all
+	parents.
++
+This results in:
++
+-----------------------------------------------------------------------
+	  .-A---N---O
+	 /     /   /
+	I---------D
+-----------------------------------------------------------------------
++
+Note how the rule to only follow the TREESAME parent, if one is
+available, removed `B` from consideration entirely.  `C` was
+considered via `N`, but is TREESAME.  Root commits are compared to an
+empty tree, so `I` is !TREESAME.
++
+Parent/child relations are only visible with `--parents`, but that does
+not affect the commits selected in default mode, so we have shown the
+parent lines.
+
+--full-history without parent rewriting::
+	This mode differs from the default in one point: always follow
+	all parents of a merge, even if it is TREESAME to one of them.
+	Even if more than one side of the merge has commits that are
+	included, this does not imply that the merge itself is!  In
+	the example, we get
++
+-----------------------------------------------------------------------
+	I  A  B  N  D  O  P  Q
+-----------------------------------------------------------------------
++
+`M` was excluded because it is TREESAME to both parents.  `E`,
+`C` and `B` were all walked, but only `B` was !TREESAME, so the others
+do not appear.
++
+Note that without parent rewriting, it is not really possible to talk
+about the parent/child relationships between the commits, so we show
+them disconnected.
+
+--full-history with parent rewriting::
+	Ordinary commits are only included if they are !TREESAME
+	(though this can be changed, see `--sparse` below).
++
+Merges are always included.  However, their parent list is rewritten:
+Along each parent, prune away commits that are not included
+themselves.  This results in
++
+-----------------------------------------------------------------------
+	  .-A---M---N---O---P---Q
+	 /     /   /   /   /
+	I     B   /   D   /
+	 \   /   /   /   /
+	  `-------------'
+-----------------------------------------------------------------------
++
+Compare to `--full-history` without rewriting above.  Note that `E`
+was pruned away because it is TREESAME, but the parent list of P was
+rewritten to contain `E`'s parent `I`.  The same happened for `C` and
+`N`, and `X`, `Y` and `Q`.
+
+In addition to the above settings, you can change whether TREESAME
+affects inclusion:
+
+--dense::
+	Commits that are walked are included if they are not TREESAME
+	to any parent.
+
+--sparse::
+	All commits that are walked are included.
++
+Note that without `--full-history`, this still simplifies merges: if
+one of the parents is TREESAME, we follow only that one, so the other
+sides of the merge are never walked.
+
+--simplify-merges::
+	First, build a history graph in the same way that
+	`--full-history` with parent rewriting does (see above).
++
+Then simplify each commit `C` to its replacement `C'` in the final
+history according to the following rules:
++
+--
+* Set `C'` to `C`.
++
+* Replace each parent `P` of `C'` with its simplification `P'`.  In
+  the process, drop parents that are ancestors of other parents or that are
+  root commits TREESAME to an empty tree, and remove duplicates, but take care
+  to never drop all parents that we are TREESAME to.
++
+* If after this parent rewriting, `C'` is a root or merge commit (has
+  zero or >1 parents), a boundary commit, or !TREESAME, it remains.
+  Otherwise, it is replaced with its only parent.
+--
++
+The effect of this is best shown by way of comparing to
+`--full-history` with parent rewriting.  The example turns into:
++
+-----------------------------------------------------------------------
+	  .-A---M---N---O
+	 /     /       /
+	I     B       D
+	 \   /       /
+	  `---------'
+-----------------------------------------------------------------------
++
+Note the major differences in `N`, `P`, and `Q` over `--full-history`:
++
+--
+* `N`'s parent list had `I` removed, because it is an ancestor of the
+  other parent `M`.  Still, `N` remained because it is !TREESAME.
++
+* `P`'s parent list similarly had `I` removed.  `P` was then
+  removed completely, because it had one parent and is TREESAME.
++
+* `Q`'s parent list had `Y` simplified to `X`. `X` was then removed, because it
+  was a TREESAME root. `Q` was then removed completely, because it had one
+  parent and is TREESAME.
+--
+
+Finally, there is a fifth simplification mode available:
+
+--ancestry-path::
+	Limit the displayed commits to those directly on the ancestry
+	chain between the ``from'' and ``to'' commits in the given commit
+	range. I.e. only display commits that are ancestor of the ``to''
+	commit and descendants of the ``from'' commit.
++
+As an example use case, consider the following commit history:
++
+-----------------------------------------------------------------------
+	    D---E-------F
+	   /     \       \
+	  B---C---G---H---I---J
+	 /                     \
+	A-------K---------------L--M
+-----------------------------------------------------------------------
++
+A regular 'D..M' computes the set of commits that are ancestors of `M`,
+but excludes the ones that are ancestors of `D`. This is useful to see
+what happened to the history leading to `M` since `D`, in the sense
+that ``what does `M` have that did not exist in `D`''. The result in this
+example would be all the commits, except `A` and `B` (and `D` itself,
+of course).
++
+When we want to find out what commits in `M` are contaminated with the
+bug introduced by `D` and need fixing, however, we might want to view
+only the subset of 'D..M' that are actually descendants of `D`, i.e.
+excluding `C` and `K`. This is exactly what the `--ancestry-path`
+option does. Applied to the 'D..M' range, it results in:
++
+-----------------------------------------------------------------------
+		E-------F
+		 \       \
+		  G---H---I---J
+			       \
+				L--M
+-----------------------------------------------------------------------
+
+The `--simplify-by-decoration` option allows you to view only the
+big picture of the topology of the history, by omitting commits
+that are not referenced by tags.  Commits are marked as !TREESAME
+(in other words, kept after history simplification rules described
+above) if (1) they are referenced by tags, or (2) they change the
+contents of the paths given on the command line.  All other
+commits are marked as TREESAME (subject to be simplified away).
+
+ifdef::git-rev-list[]
+Bisection Helpers
+~~~~~~~~~~~~~~~~~
+
+--bisect::
+	Limit output to the one commit object which is roughly halfway between
+	included and excluded commits. Note that the bad bisection ref
+	`refs/bisect/bad` is added to the included commits (if it
+	exists) and the good bisection refs `refs/bisect/good-*` are
+	added to the excluded commits (if they exist). Thus, supposing there
+	are no refs in `refs/bisect/`, if
++
+-----------------------------------------------------------------------
+	$ git rev-list --bisect foo ^bar ^baz
+-----------------------------------------------------------------------
++
+outputs 'midpoint', the output of the two commands
++
+-----------------------------------------------------------------------
+	$ git rev-list foo ^midpoint
+	$ git rev-list midpoint ^bar ^baz
+-----------------------------------------------------------------------
++
+would be of roughly the same length.  Finding the change which
+introduces a regression is thus reduced to a binary search: repeatedly
+generate and test new 'midpoint's until the commit chain is of length
+one. Cannot be combined with --first-parent.
+
+--bisect-vars::
+	This calculates the same as `--bisect`, except that refs in
+	`refs/bisect/` are not used, and except that this outputs
+	text ready to be eval'ed by the shell. These lines will assign the
+	name of the midpoint revision to the variable `bisect_rev`, and the
+	expected number of commits to be tested after `bisect_rev` is tested
+	to `bisect_nr`, the expected number of commits to be tested if
+	`bisect_rev` turns out to be good to `bisect_good`, the expected
+	number of commits to be tested if `bisect_rev` turns out to be bad to
+	`bisect_bad`, and the number of commits we are bisecting right now to
+	`bisect_all`.
+
+--bisect-all::
+	This outputs all the commit objects between the included and excluded
+	commits, ordered by their distance to the included and excluded
+	commits. Refs in `refs/bisect/` are not used. The farthest
+	from them is displayed first. (This is the only one displayed by
+	`--bisect`.)
++
+This is useful because it makes it easy to choose a good commit to
+test when you want to avoid to test some of them for some reason (they
+may not compile for example).
++
+This option can be used along with `--bisect-vars`, in this case,
+after all the sorted commit objects, there will be the same text as if
+`--bisect-vars` had been used alone.
+endif::git-rev-list[]
+
+
+Commit Ordering
+~~~~~~~~~~~~~~~
+
+By default, the commits are shown in reverse chronological order.
+
+--date-order::
+	Show no parents before all of its children are shown, but
+	otherwise show commits in the commit timestamp order.
+
+--author-date-order::
+	Show no parents before all of its children are shown, but
+	otherwise show commits in the author timestamp order.
+
+--topo-order::
+	Show no parents before all of its children are shown, and
+	avoid showing commits on multiple lines of history
+	intermixed.
++
+For example, in a commit history like this:
++
+----------------------------------------------------------------
+
+    ---1----2----4----7
+	\	       \
+	 3----5----6----8---
+
+----------------------------------------------------------------
++
+where the numbers denote the order of commit timestamps, `git
+rev-list` and friends with `--date-order` show the commits in the
+timestamp order: 8 7 6 5 4 3 2 1.
++
+With `--topo-order`, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5
+3 1); some older commits are shown before newer ones in order to
+avoid showing the commits from two parallel development track mixed
+together.
+
+--reverse::
+	Output the commits in reverse order.
+	Cannot be combined with `--walk-reflogs`.
+
+Object Traversal
+~~~~~~~~~~~~~~~~
+
+These options are mostly targeted for packing of Git repositories.
+
+ifdef::git-rev-list[]
+--objects::
+	Print the object IDs of any object referenced by the listed
+	commits.  `--objects foo ^bar` thus means ``send me
+	all object IDs which I need to download if I have the commit
+	object _bar_ but not _foo_''.
+
+--objects-edge::
+	Similar to `--objects`, but also print the IDs of excluded
+	commits prefixed with a ``-'' character.  This is used by
+	linkgit:git-pack-objects[1] to build a ``thin'' pack, which records
+	objects in deltified form based on objects contained in these
+	excluded commits to reduce network traffic.
+
+--objects-edge-aggressive::
+	Similar to `--objects-edge`, but it tries harder to find excluded
+	commits at the cost of increased time.  This is used instead of
+	`--objects-edge` to build ``thin'' packs for shallow repositories.
+
+--indexed-objects::
+	Pretend as if all trees and blobs used by the index are listed
+	on the command line.  Note that you probably want to use
+	`--objects`, too.
+
+--unpacked::
+	Only useful with `--objects`; print the object IDs that are not
+	in packs.
+endif::git-rev-list[]
+
+--no-walk[=(sorted|unsorted)]::
+	Only show the given commits, but do not traverse their ancestors.
+	This has no effect if a range is specified. If the argument
+	`unsorted` is given, the commits are shown in the order they were
+	given on the command line. Otherwise (if `sorted` or no argument
+	was given), the commits are shown in reverse chronological order
+	by commit time.
+	Cannot be combined with `--graph`.
+
+--do-walk::
+	Overrides a previous `--no-walk`.
+
+Commit Formatting
+~~~~~~~~~~~~~~~~~
+
+ifdef::git-rev-list[]
+Using these options, linkgit:git-rev-list[1] will act similar to the
+more specialized family of commit log tools: linkgit:git-log[1],
+linkgit:git-show[1], and linkgit:git-whatchanged[1]
+endif::git-rev-list[]
+
+include::pretty-options.txt[]
+
+--relative-date::
+	Synonym for `--date=relative`.
+
+--date=(relative|local|default|iso|iso-strict|rfc|short|raw)::
+	Only takes effect for dates shown in human-readable format, such
+	as when using `--pretty`. `log.date` config variable sets a default
+	value for the log command's `--date` option.
++
+`--date=relative` shows dates relative to the current time,
+e.g. ``2 hours ago''.
++
+`--date=local` shows timestamps in user's local time zone.
++
+`--date=iso` (or `--date=iso8601`) shows timestamps in a ISO 8601-like format.
+The differences to the strict ISO 8601 format are:
+
+	- a space instead of the `T` date/time delimiter
+	- a space between time and time zone
+	- no colon between hours and minutes of the time zone
+
++
+`--date=iso-strict` (or `--date=iso8601-strict`) shows timestamps in strict
+ISO 8601 format.
++
+`--date=rfc` (or `--date=rfc2822`) shows timestamps in RFC 2822
+format, often found in email messages.
++
+`--date=short` shows only the date, but not the time, in `YYYY-MM-DD` format.
++
+`--date=raw` shows the date in the internal raw Git format `%s %z` format.
++
+`--date=format:...` feeds the format `...` to your system `strftime`.
+Use `--date=format:%c` to show the date in your system locale's
+preferred format.  See the `strftime` manual for a complete list of
+format placeholders.
++
+`--date=default` shows timestamps in the original time zone
+(either committer's or author's).
+
+ifdef::git-rev-list[]
+--header::
+	Print the contents of the commit in raw-format; each record is
+	separated with a NUL character.
+endif::git-rev-list[]
+
+--parents::
+	Print also the parents of the commit (in the form "commit parent...").
+	Also enables parent rewriting, see 'History Simplification' below.
+
+--children::
+	Print also the children of the commit (in the form "commit child...").
+	Also enables parent rewriting, see 'History Simplification' below.
+
+ifdef::git-rev-list[]
+--timestamp::
+	Print the raw commit timestamp.
+endif::git-rev-list[]
+
+--left-right::
+	Mark which side of a symmetric diff a commit is reachable from.
+	Commits from the left side are prefixed with `<` and those from
+	the right with `>`.  If combined with `--boundary`, those
+	commits are prefixed with `-`.
++
+For example, if you have this topology:
++
+-----------------------------------------------------------------------
+	     y---b---b  branch B
+	    / \ /
+	   /   .
+	  /   / \
+	 o---x---a---a  branch A
+-----------------------------------------------------------------------
++
+you would get an output like this:
++
+-----------------------------------------------------------------------
+	$ git rev-list --left-right --boundary --pretty=oneline A...B
+
+	>bbbbbbb... 3rd on b
+	>bbbbbbb... 2nd on b
+	<aaaaaaa... 3rd on a
+	<aaaaaaa... 2nd on a
+	-yyyyyyy... 1st on b
+	-xxxxxxx... 1st on a
+-----------------------------------------------------------------------
+
+--graph::
+	Draw a text-based graphical representation of the commit history
+	on the left hand side of the output.  This may cause extra lines
+	to be printed in between commits, in order for the graph history
+	to be drawn properly.
+	Cannot be combined with `--no-walk`.
++
+This enables parent rewriting, see 'History Simplification' below.
++
+This implies the `--topo-order` option by default, but the
+`--date-order` option may also be specified.
+
+--show-linear-break[=<barrier>]::
+	When --graph is not used, all history branches are flattened
+	which can make it hard to see that the two consecutive commits
+	do not belong to a linear branch. This option puts a barrier
+	in between them in that case. If `<barrier>` is specified, it
+	is the string that will be shown instead of the default one.
+
+ifdef::git-rev-list[]
+--count::
+	Print a number stating how many commits would have been
+	listed, and suppress all other output.  When used together
+	with `--left-right`, instead print the counts for left and
+	right commits, separated by a tab. When used together with
+	`--cherry-mark`, omit patch equivalent commits from these
+	counts and print the count for equivalent commits separated
+	by a tab.
+endif::git-rev-list[]

+ifndef::git-rev-list[]
+Diff Formatting
+~~~~~~~~~~~~~~~
+
+Listed below are options that control the formatting of diff output.
+Some of them are specific to linkgit:git-rev-list[1], however other diff
+options may be given. See linkgit:git-diff-files[1] for more options.
+
+-c::
+	With this option, diff output for a merge commit
+	shows the differences from each of the parents to the merge result
+	simultaneously instead of showing pairwise diff between a parent
+	and the result one at a time. Furthermore, it lists only files
+	which were modified from all parents.
+
+--cc::
+	This flag implies the `-c` option and further compresses the
+	patch output by omitting uninteresting hunks whose contents in
+	the parents have only two variants and the merge result picks
+	one of them without modification.
+
+-m::
+	This flag makes the merge commits show the full diff like
+	regular commits; for each merge parent, a separate log entry
+	and diff is generated. An exception is that only diff against
+	the first parent is shown when `--first-parent` option is given;
+	in that case, the output represents the changes the merge
+	brought _into_ the then-current branch.
+
+-r::
+	Show recursive diffs.
+
+-t::
+	Show the tree objects in the diff output. This implies `-r`.

+SPECIFYING REVISIONS
+--------------------
+
+A revision parameter '<rev>' typically, but not necessarily, names a
+commit object.  It uses what is called an 'extended SHA-1'
+syntax.  Here are various ways to spell object names.  The
+ones listed near the end of this list name trees and
+blobs contained in a commit.
+
+'<sha1>', e.g. 'dae86e1950b1277e545cee180551750029cfe735', 'dae86e'::
+  The full SHA-1 object name (40-byte hexadecimal string), or
+  a leading substring that is unique within the repository.
+  E.g. dae86e1950b1277e545cee180551750029cfe735 and dae86e both
+  name the same commit object if there is no other object in
+  your repository whose object name starts with dae86e.
+
+'<describeOutput>', e.g. 'v1.7.4.2-679-g3bee7fb'::
+  Output from `git describe`; i.e. a closest tag, optionally
+  followed by a dash and a number of commits, followed by a dash, a
+  'g', and an abbreviated object name.
+
+'<refname>', e.g. 'master', 'heads/master', 'refs/heads/master'::
+  A symbolic ref name.  E.g. 'master' typically means the commit
+  object referenced by 'refs/heads/master'.  If you
+  happen to have both 'heads/master' and 'tags/master', you can
+  explicitly say 'heads/master' to tell Git which one you mean.
+  When ambiguous, a '<refname>' is disambiguated by taking the
+  first match in the following rules:
+
+  . If '$GIT_DIR/<refname>' exists, that is what you mean (this is usually
+    useful only for 'HEAD', 'FETCH_HEAD', 'ORIG_HEAD', 'MERGE_HEAD'
+    and 'CHERRY_PICK_HEAD');
+
+  . otherwise, 'refs/<refname>' if it exists;
+
+  . otherwise, 'refs/tags/<refname>' if it exists;
+
+  . otherwise, 'refs/heads/<refname>' if it exists;
+
+  . otherwise, 'refs/remotes/<refname>' if it exists;
+
+  . otherwise, 'refs/remotes/<refname>/HEAD' if it exists.
++
+'HEAD' names the commit on which you based the changes in the working tree.
+'FETCH_HEAD' records the branch which you fetched from a remote repository
+with your last `git fetch` invocation.
+'ORIG_HEAD' is created by commands that move your 'HEAD' in a drastic
+way, to record the position of the 'HEAD' before their operation, so that
+you can easily change the tip of the branch back to the state before you ran
+them.
+'MERGE_HEAD' records the commit(s) which you are merging into your branch
+when you run `git merge`.
+'CHERRY_PICK_HEAD' records the commit which you are cherry-picking
+when you run `git cherry-pick`.
++
+Note that any of the 'refs/*' cases above may come either from
+the '$GIT_DIR/refs' directory or from the '$GIT_DIR/packed-refs' file.
+While the ref name encoding is unspecified, UTF-8 is preferred as
+some output processing may assume ref names in UTF-8.
+
+'@'::
+  '@' alone is a shortcut for 'HEAD'.
+
+'<refname>@\{<date>\}', e.g. 'master@\{yesterday\}', 'HEAD@\{5 minutes ago\}'::
+  A ref followed by the suffix '@' with a date specification
+  enclosed in a brace
+  pair (e.g. '\{yesterday\}', '\{1 month 2 weeks 3 days 1 hour 1
+  second ago\}' or '\{1979-02-26 18:30:00\}') specifies the value
+  of the ref at a prior point in time.  This suffix may only be
+  used immediately following a ref name and the ref must have an
+  existing log ('$GIT_DIR/logs/<ref>'). Note that this looks up the state
+  of your *local* ref at a given time; e.g., what was in your local
+  'master' branch last week. If you want to look at commits made during
+  certain times, see '--since' and '--until'.
+
+'<refname>@\{<n>\}', e.g. 'master@\{1\}'::
+  A ref followed by the suffix '@' with an ordinal specification
+  enclosed in a brace pair (e.g. '\{1\}', '\{15\}') specifies
+  the n-th prior value of that ref.  For example 'master@\{1\}'
+  is the immediate prior value of 'master' while 'master@\{5\}'
+  is the 5th prior value of 'master'. This suffix may only be used
+  immediately following a ref name and the ref must have an existing
+  log ('$GIT_DIR/logs/<refname>').
+
+'@\{<n>\}', e.g. '@\{1\}'::
+  You can use the '@' construct with an empty ref part to get at a
+  reflog entry of the current branch. For example, if you are on
+  branch 'blabla' then '@\{1\}' means the same as 'blabla@\{1\}'.
+
+'@\{-<n>\}', e.g. '@\{-1\}'::
+  The construct '@\{-<n>\}' means the <n>th branch/commit checked out
+  before the current one.
+
+'<branchname>@\{upstream\}', e.g. 'master@\{upstream\}', '@\{u\}'::
+  The suffix '@\{upstream\}' to a branchname (short form '<branchname>@\{u\}')
+  refers to the branch that the branch specified by branchname is set to build on
+  top of (configured with `branch.<name>.remote` and
+  `branch.<name>.merge`).  A missing branchname defaults to the
+  current one.
+
+'<branchname>@\{push\}', e.g. 'master@\{push\}', '@\{push\}'::
+  The suffix '@\{push}' reports the branch "where we would push to" if
+  `git push` were run while `branchname` was checked out (or the current
+  'HEAD' if no branchname is specified). Since our push destination is
+  in a remote repository, of course, we report the local tracking branch
+  that corresponds to that branch (i.e., something in 'refs/remotes/').
++
+Here's an example to make it more clear:
++
+------------------------------
+$ git config push.default current
+$ git config remote.pushdefault myfork
+$ git checkout -b mybranch origin/master
+
+$ git rev-parse --symbolic-full-name @{upstream}
+refs/remotes/origin/master
+
+$ git rev-parse --symbolic-full-name @{push}
+refs/remotes/myfork/mybranch
+------------------------------
++
+Note in the example that we set up a triangular workflow, where we pull
+from one location and push to another. In a non-triangular workflow,
+'@\{push}' is the same as '@\{upstream}', and there is no need for it.
+
+'<rev>{caret}', e.g. 'HEAD{caret}, v1.5.1{caret}0'::
+  A suffix '{caret}' to a revision parameter means the first parent of
+  that commit object.  '{caret}<n>' means the <n>th parent (i.e.
+  '<rev>{caret}'
+  is equivalent to '<rev>{caret}1').  As a special rule,
+  '<rev>{caret}0' means the commit itself and is used when '<rev>' is the
+  object name of a tag object that refers to a commit object.
+
+'<rev>{tilde}<n>', e.g. 'master{tilde}3'::
+  A suffix '{tilde}<n>' to a revision parameter means the commit
+  object that is the <n>th generation ancestor of the named
+  commit object, following only the first parents.  I.e. '<rev>{tilde}3' is
+  equivalent to '<rev>{caret}{caret}{caret}' which is equivalent to
+  '<rev>{caret}1{caret}1{caret}1'.  See below for an illustration of
+  the usage of this form.
+
+'<rev>{caret}\{<type>\}', e.g. 'v0.99.8{caret}\{commit\}'::
+  A suffix '{caret}' followed by an object type name enclosed in
+  brace pair means dereference the object at '<rev>' recursively until
+  an object of type '<type>' is found or the object cannot be
+  dereferenced anymore (in which case, barf).
+  For example, if '<rev>' is a commit-ish, '<rev>{caret}\{commit\}'
+  describes the corresponding commit object.
+  Similarly, if '<rev>' is a tree-ish, '<rev>{caret}\{tree\}'
+  describes the corresponding tree object.
+  '<rev>{caret}0'
+  is a short-hand for '<rev>{caret}\{commit\}'.
++
+'rev{caret}\{object\}' can be used to make sure 'rev' names an
+object that exists, without requiring 'rev' to be a tag, and
+without dereferencing 'rev'; because a tag is already an object,
+it does not have to be dereferenced even once to get to an object.
++
+'rev{caret}\{tag\}' can be used to ensure that 'rev' identifies an
+existing tag object.
+
+'<rev>{caret}\{\}', e.g. 'v0.99.8{caret}\{\}'::
+  A suffix '{caret}' followed by an empty brace pair
+  means the object could be a tag,
+  and dereference the tag recursively until a non-tag object is
+  found.
+
+'<rev>{caret}\{/<text>\}', e.g. 'HEAD^{/fix nasty bug}'::
+  A suffix '{caret}' to a revision parameter, followed by a brace
+  pair that contains a text led by a slash,
+  is the same as the ':/fix nasty bug' syntax below except that
+  it returns the youngest matching commit which is reachable from
+  the '<rev>' before '{caret}'.
+
+':/<text>', e.g. ':/fix nasty bug'::
+  A colon, followed by a slash, followed by a text, names
+  a commit whose commit message matches the specified regular expression.
+  This name returns the youngest matching commit which is
+  reachable from any ref.  If the commit message starts with a
+  '!' you have to repeat that;  the special sequence ':/!',
+  followed by something else than '!', is reserved for now.
+  The regular expression can match any part of the commit message. To
+  match messages starting with a string, one can use e.g. ':/^foo'.
+
+'<rev>:<path>', e.g. 'HEAD:README', ':README', 'master:./README'::
+  A suffix ':' followed by a path names the blob or tree
+  at the given path in the tree-ish object named by the part
+  before the colon.
+  ':path' (with an empty part before the colon)
+  is a special case of the syntax described next: content
+  recorded in the index at the given path.
+  A path starting with './' or '../' is relative to the current working directory.
+  The given path will be converted to be relative to the working tree's root directory.
+  This is most useful to address a blob or tree from a commit or tree that has
+  the same tree structure as the working tree.
+
+':<n>:<path>', e.g. ':0:README', ':README'::
+  A colon, optionally followed by a stage number (0 to 3) and a
+  colon, followed by a path, names a blob object in the
+  index at the given path. A missing stage number (and the colon
+  that follows it) names a stage 0 entry. During a merge, stage
+  1 is the common ancestor, stage 2 is the target branch's version
+  (typically the current branch), and stage 3 is the version from
+  the branch which is being merged.
+
+Here is an illustration, by Jon Loeliger.  Both commit nodes B
+and C are parents of commit node A.  Parent commits are ordered
+left-to-right.
+
+........................................
+G   H   I   J
+ \ /     \ /
+  D   E   F
+   \  |  / \

+       \   /
+        \ /
+         A

+
+    A =      = A^0
+    B = A^   = A^1     = A~1
+    C = A^2  = A^2
+    D = A^^  = A^1^1   = A~2
+    E = B^2  = A^^2
+    F = B^3  = A^^3
+    G = A^^^ = A^1^1^1 = A~3
+    H = D^2  = B^^2    = A^^^2  = A~2^2
+    I = F^   = B^3^    = A^^3^
+    J = F^2  = B^3^2   = A^^3^2
+
+
+SPECIFYING RANGES
+-----------------
+
+History traversing commands such as `git log` operate on a set
+of commits, not just a single commit.  To these commands,
+specifying a single revision with the notation described in the
+previous section means the set of commits reachable from that
+commit, following the commit ancestry chain.
+
+To exclude commits reachable from a commit, a prefix '{caret}'
+notation is used.  E.g. '{caret}r1 r2' means commits reachable
+from 'r2' but exclude the ones reachable from 'r1'.
+
+This set operation appears so often that there is a shorthand
+for it.  When you have two commits 'r1' and 'r2' (named according
+to the syntax explained in SPECIFYING REVISIONS above), you can ask
+for commits that are reachable from r2 excluding those that are reachable
+from r1 by '{caret}r1 r2' and it can be written as 'r1..r2'.
+
+A similar notation 'r1\...r2' is called symmetric difference
+of 'r1' and 'r2' and is defined as
+'r1 r2 --not $(git merge-base --all r1 r2)'.
+It is the set of commits that are reachable from either one of
+'r1' or 'r2' but not from both.
+
+In these two shorthands, you can omit one end and let it default to HEAD.
+For example, 'origin..' is a shorthand for 'origin..HEAD' and asks "What
+did I do since I forked from the origin branch?"  Similarly, '..origin'
+is a shorthand for 'HEAD..origin' and asks "What did the origin do since
+I forked from them?"  Note that '..' would mean 'HEAD..HEAD' which is an
+empty range that is both reachable and unreachable from HEAD.
+
+Two other shorthands for naming a set that is formed by a commit
+and its parent commits exist.  The 'r1{caret}@' notation means all
+parents of 'r1'.  'r1{caret}!' includes commit 'r1' but excludes
+all of its parents.
+
+To summarize:
+
+'<rev>'::
+	Include commits that are reachable from (i.e. ancestors of)
+	<rev>.
+
+'{caret}<rev>'::
+	Exclude commits that are reachable from (i.e. ancestors of)
+	<rev>.
+
+'<rev1>..<rev2>'::
+	Include commits that are reachable from <rev2> but exclude
+	those that are reachable from <rev1>.  When either <rev1> or
+	<rev2> is omitted, it defaults to 'HEAD'.
+
+'<rev1>\...<rev2>'::
+	Include commits that are reachable from either <rev1> or
+	<rev2> but exclude those that are reachable from both.  When
+	either <rev1> or <rev2> is omitted, it defaults to 'HEAD'.
+
+'<rev>{caret}@', e.g. 'HEAD{caret}@'::
+  A suffix '{caret}' followed by an at sign is the same as listing
+  all parents of '<rev>' (meaning, include anything reachable from
+  its parents, but not the commit itself).
+
+'<rev>{caret}!', e.g. 'HEAD{caret}!'::
+  A suffix '{caret}' followed by an exclamation mark is the same
+  as giving commit '<rev>' and then all its parents prefixed with
+  '{caret}' to exclude them (and their ancestors).
+
+Here are a handful of examples:
+
+   D                G H D
+   D F              G H I J D F
+   ^G D             H D
+   ^D B             E I J F B
+   B..C             C
+   B...C            G H D E B C
+   ^D B C           E I J F B C
+   C                I J F C
+   C^@              I J F

+allocation growing API
+======================
+
+Dynamically growing an array using realloc() is error prone and boring.
+
+Define your array with:
+
+* a pointer (`item`) that points at the array, initialized to `NULL`
+  (although please name the variable based on its contents, not on its
+  type);
+
+* an integer variable (`alloc`) that keeps track of how big the current
+  allocation is, initialized to `0`;
+
+* another integer variable (`nr`) to keep track of how many elements the
+  array currently has, initialized to `0`.
+
+Then before adding `n`th element to the item, call `ALLOC_GROW(item, n,
+alloc)`.  This ensures that the array can hold at least `n` elements by
+calling `realloc(3)` and adjusting `alloc` variable.
+
+------------
+sometype *item;
+size_t nr;
+size_t alloc
+
+for (i = 0; i < nr; i++)
+	if (we like item[i] already)
+		return;
+
+/* we did not like any existing one, so add one */
+ALLOC_GROW(item, nr + 1, alloc);
+item[nr++] = value you like;
+------------
+
+You are responsible for updating the `nr` variable.
+
+If you need to specify the number of elements to allocate explicitly
+then use the macro `REALLOC_ARRAY(item, alloc)` instead of `ALLOC_GROW`.

+argv-array API
+==============
+
+The argv-array API allows one to dynamically build and store
+NULL-terminated lists.  An argv-array maintains the invariant that the
+`argv` member always points to a non-NULL array, and that the array is
+always NULL-terminated at the element pointed to by `argv[argc]`. This
+makes the result suitable for passing to functions expecting to receive
+argv from main(), or the link:api-run-command.html[run-command API].
+
+The link:api-string-list.html[string-list API] is similar, but cannot be
+used for these purposes; instead of storing a straight string pointer,
+it contains an item structure with a `util` field that is not compatible
+with the traditional argv interface.
+
+Each `argv_array` manages its own memory. Any strings pushed into the
+array are duplicated, and all memory is freed by argv_array_clear().
+
+Data Structures
+---------------
+
+`struct argv_array`::
+
+	A single array. This should be initialized by assignment from
+	`ARGV_ARRAY_INIT`, or by calling `argv_array_init`. The `argv`
+	member contains the actual array; the `argc` member contains the
+	number of elements in the array, not including the terminating
+	NULL.
+
+Functions
+---------
+
+`argv_array_init`::
+	Initialize an array. This is no different than assigning from
+	`ARGV_ARRAY_INIT`.
+
+`argv_array_push`::
+	Push a copy of a string onto the end of the array.
+
+`argv_array_pushl`::
+	Push a list of strings onto the end of the array. The arguments
+	should be a list of `const char *` strings, terminated by a NULL
+	argument.
+
+`argv_array_pushf`::
+	Format a string and push it onto the end of the array. This is a
+	convenience wrapper combining `strbuf_addf` and `argv_array_push`.
+
+`argv_array_pushv`::
+	Push a null-terminated array of strings onto the end of the array.
+
+`argv_array_pop`::
+	Remove the final element from the array. If there are no
+	elements in the array, do nothing.
+
+`argv_array_clear`::
+	Free all memory associated with the array and return it to the
+	initial, empty state.

+builtin API
+===========
+
+Adding a new built-in
+---------------------
+
+There are 4 things to do to add a built-in command implementation to
+Git:
+
+. Define the implementation of the built-in command `foo` with
+  signature:
+
+	int cmd_foo(int argc, const char **argv, const char *prefix);
+
+. Add the external declaration for the function to `builtin.h`.
+
+. Add the command to the `commands[]` table defined in `git.c`.
+  The entry should look like:
+
+	{ "foo", cmd_foo, <options> },
++
+where options is the bitwise-or of:
+
+`RUN_SETUP`::
+	If there is not a Git directory to work on, abort.  If there
+	is a work tree, chdir to the top of it if the command was
+	invoked in a subdirectory.  If there is no work tree, no
+	chdir() is done.
+
+`RUN_SETUP_GENTLY`::
+	If there is a Git directory, chdir as per RUN_SETUP, otherwise,
+	don't chdir anywhere.
+
+`USE_PAGER`::
+
+	If the standard output is connected to a tty, spawn a pager and
+	feed our output to it.
+
+`NEED_WORK_TREE`::
+
+	Make sure there is a work tree, i.e. the command cannot act
+	on bare repositories.
+	This only makes sense when `RUN_SETUP` is also set.
+
+. Add `builtin/foo.o` to `BUILTIN_OBJS` in `Makefile`.
+
+Additionally, if `foo` is a new command, there are 3 more things to do:
+
+. Add tests to `t/` directory.
+
+. Write documentation in `Documentation/git-foo.txt`.
+
+. Add an entry for `git-foo` to `command-list.txt`.
+
+. Add an entry for `/git-foo` to `.gitignore`.
+
+
+How a built-in is called
+------------------------
+
+The implementation `cmd_foo()` takes three parameters, `argc`, `argv,
+and `prefix`.  The first two are similar to what `main()` of a
+standalone command would be called with.
+
+When `RUN_SETUP` is specified in the `commands[]` table, and when you
+were started from a subdirectory of the work tree, `cmd_foo()` is called
+after chdir(2) to the top of the work tree, and `prefix` gets the path
+to the subdirectory the command started from.  This allows you to
+convert a user-supplied pathname (typically relative to that directory)
+to a pathname relative to the top of the work tree.
+
+The return value from `cmd_foo()` becomes the exit status of the
+command.

+config API
+==========
+
+The config API gives callers a way to access Git configuration files
+(and files which have the same syntax). See linkgit:git-config[1] for a
+discussion of the config file syntax.
+
+General Usage
+-------------
+
+Config files are parsed linearly, and each variable found is passed to a
+caller-provided callback function. The callback function is responsible
+for any actions to be taken on the config option, and is free to ignore
+some options. It is not uncommon for the configuration to be parsed
+several times during the run of a Git program, with different callbacks
+picking out different variables useful to themselves.
+
+A config callback function takes three parameters:
+
+- the name of the parsed variable. This is in canonical "flat" form: the
+  section, subsection, and variable segments will be separated by dots,
+  and the section and variable segments will be all lowercase. E.g.,
+  `core.ignorecase`, `diff.SomeType.textconv`.
+
+- the value of the found variable, as a string. If the variable had no
+  value specified, the value will be NULL (typically this means it
+  should be interpreted as boolean true).
+
+- a void pointer passed in by the caller of the config API; this can
+  contain callback-specific data
+
+A config callback should return 0 for success, or -1 if the variable
+could not be parsed properly.
+
+Basic Config Querying
+---------------------
+
+Most programs will simply want to look up variables in all config files
+that Git knows about, using the normal precedence rules. To do this,
+call `git_config` with a callback function and void data pointer.
+
+`git_config` will read all config sources in order of increasing
+priority. Thus a callback should typically overwrite previously-seen
+entries with new ones (e.g., if both the user-wide `~/.gitconfig` and
+repo-specific `.git/config` contain `color.ui`, the config machinery
+will first feed the user-wide one to the callback, and then the
+repo-specific one; by overwriting, the higher-priority repo-specific
+value is left at the end).
+
+The `git_config_with_options` function lets the caller examine config
+while adjusting some of the default behavior of `git_config`. It should
+almost never be used by "regular" Git code that is looking up
+configuration variables. It is intended for advanced callers like
+`git-config`, which are intentionally tweaking the normal config-lookup
+process. It takes two extra parameters:
+
+`filename`::
+If this parameter is non-NULL, it specifies the name of a file to
+parse for configuration, rather than looking in the usual files. Regular
+`git_config` defaults to `NULL`.
+
+`respect_includes`::
+Specify whether include directives should be followed in parsed files.
+Regular `git_config` defaults to `1`.
+
+There is a special version of `git_config` called `git_config_early`.
+This version takes an additional parameter to specify the repository
+config, instead of having it looked up via `git_path`. This is useful
+early in a Git program before the repository has been found. Unless
+you're working with early setup code, you probably don't want to use
+this.
+
+Reading Specific Files
+----------------------
+
+To read a specific file in git-config format, use
+`git_config_from_file`. This takes the same callback and data parameters
+as `git_config`.
+
+Querying For Specific Variables
+-------------------------------
+
+For programs wanting to query for specific variables in a non-callback
+manner, the config API provides two functions `git_config_get_value`
+and `git_config_get_value_multi`. They both read values from an internal
+cache generated previously from reading the config files.
+
+`int git_config_get_value(const char *key, const char **value)`::
+
+	Finds the highest-priority value for the configuration variable `key`,
+	stores the pointer to it in `value` and returns 0. When the
+	configuration variable `key` is not found, returns 1 without touching
+	`value`. The caller should not free or modify `value`, as it is owned
+	by the cache.
+
+`const struct string_list *git_config_get_value_multi(const char *key)`::
+
+	Finds and returns the value list, sorted in order of increasing priority
+	for the configuration variable `key`. When the configuration variable
+	`key` is not found, returns NULL. The caller should not free or modify
+	the returned pointer, as it is owned by the cache.
+
+`void git_config_clear(void)`::
+
+	Resets and invalidates the config cache.
+
+The config API also provides type specific API functions which do conversion
+as well as retrieval for the queried variable, including:
+
+`int git_config_get_int(const char *key, int *dest)`::
+
+	Finds and parses the value to an integer for the configuration variable
+	`key`. Dies on error; otherwise, stores the value of the parsed integer in
+	`dest` and returns 0. When the configuration variable `key` is not found,
+	returns 1 without touching `dest`.
+
+`int git_config_get_ulong(const char *key, unsigned long *dest)`::
+
+	Similar to `git_config_get_int` but for unsigned longs.
+
+`int git_config_get_bool(const char *key, int *dest)`::
+
+	Finds and parses the value into a boolean value, for the configuration
+	variable `key` respecting keywords like "true" and "false". Integer
+	values are converted into true/false values (when they are non-zero or
+	zero, respectively). Other values cause a die(). If parsing is successful,
+	stores the value of the parsed result in `dest` and returns 0. When the
+	configuration variable `key` is not found, returns 1 without touching
+	`dest`.
+
+`int git_config_get_bool_or_int(const char *key, int *is_bool, int *dest)`::
+
+	Similar to `git_config_get_bool`, except that integers are copied as-is,
+	and `is_bool` flag is unset.
+
+`int git_config_get_maybe_bool(const char *key, int *dest)`::
+
+	Similar to `git_config_get_bool`, except that it returns -1 on error
+	rather than dying.
+
+`int git_config_get_string_const(const char *key, const char **dest)`::
+
+	Allocates and copies the retrieved string into the `dest` parameter for
+	the configuration variable `key`; if NULL string is given, prints an
+	error message and returns -1. When the configuration variable `key` is
+	not found, returns 1 without touching `dest`.
+
+`int git_config_get_string(const char *key, char **dest)`::
+
+	Similar to `git_config_get_string_const`, except that retrieved value
+	copied into the `dest` parameter is a mutable string.
+
+`int git_config_get_pathname(const char *key, const char **dest)`::
+
+	Similar to `git_config_get_string`, but expands `~` or `~user` into
+	the user's home directory when found at the beginning of the path.
+
+`git_die_config(const char *key, const char *err, ...)`::
+
+	First prints the error message specified by the caller in `err` and then
+	dies printing the line number and the file name of the highest priority
+	value for the configuration variable `key`.
+
+`void git_die_config_linenr(const char *key, const char *filename, int linenr)`::
+
+	Helper function which formats the die error message according to the
+	parameters entered. Used by `git_die_config()`. It can be used by callers
+	handling `git_config_get_value_multi()` to print the correct error message
+	for the desired value.
+
+See test-config.c for usage examples.
+
+Value Parsing Helpers
+---------------------
+
+To aid in parsing string values, the config API provides callbacks with
+a number of helper functions, including:
+
+`git_config_int`::
+Parse the string to an integer, including unit factors. Dies on error;
+otherwise, returns the parsed result.
+
+`git_config_ulong`::
+Identical to `git_config_int`, but for unsigned longs.
+
+`git_config_bool`::
+Parse a string into a boolean value, respecting keywords like "true" and
+"false". Integer values are converted into true/false values (when they
+are non-zero or zero, respectively). Other values cause a die(). If
+parsing is successful, the return value is the result.
+
+`git_config_bool_or_int`::
+Same as `git_config_bool`, except that integers are returned as-is, and
+an `is_bool` flag is unset.
+
+`git_config_maybe_bool`::
+Same as `git_config_bool`, except that it returns -1 on error rather
+than dying.
+
+`git_config_string`::
+Allocates and copies the value string into the `dest` parameter; if no
+string is given, prints an error message and returns -1.
+
+`git_config_pathname`::
+Similar to `git_config_string`, but expands `~` or `~user` into the
+user's home directory when found at the beginning of the path.
+
+Include Directives
+------------------
+
+By default, the config parser does not respect include directives.
+However, a caller can use the special `git_config_include` wrapper
+callback to support them. To do so, you simply wrap your "real" callback
+function and data pointer in a `struct config_include_data`, and pass
+the wrapper to the regular config-reading functions. For example:
+
+-------------------------------------------
+int read_file_with_include(const char *file, config_fn_t fn, void *data)
+{
+	struct config_include_data inc = CONFIG_INCLUDE_INIT;
+	inc.fn = fn;
+	inc.data = data;
+	return git_config_from_file(git_config_include, file, &inc);
+}
+-------------------------------------------
+
+`git_config` respects includes automatically. The lower-level
+`git_config_from_file` does not.
+
+Custom Configsets
+-----------------
+
+A `config_set` can be used to construct an in-memory cache for
+config-like files that the caller specifies (i.e., files like `.gitmodules`,
+`~/.gitconfig` etc.). For example,
+
+---------------------------------------
+struct config_set gm_config;
+git_configset_init(&gm_config);
+int b;
+/* we add config files to the config_set */
+git_configset_add_file(&gm_config, ".gitmodules");
+git_configset_add_file(&gm_config, ".gitmodules_alt");
+
+if (!git_configset_get_bool(gm_config, "submodule.frotz.ignore", &b)) {
+	/* hack hack hack */
+}
+
+/* when we are done with the configset */
+git_configset_clear(&gm_config);
+----------------------------------------
+
+Configset API provides functions for the above mentioned work flow, including:
+
+`void git_configset_init(struct config_set *cs)`::
+
+	Initializes the config_set `cs`.
+
+`int git_configset_add_file(struct config_set *cs, const char *filename)`::
+
+	Parses the file and adds the variable-value pairs to the `config_set`,
+	dies if there is an error in parsing the file. Returns 0 on success, or
+	-1 if the file does not exist or is inaccessible. The user has to decide
+	if he wants to free the incomplete configset or continue using it when
+	the function returns -1.
+
+`int git_configset_get_value(struct config_set *cs, const char *key, const char **value)`::
+
+	Finds the highest-priority value for the configuration variable `key`
+	and config set `cs`, stores the pointer to it in `value` and returns 0.
+	When the configuration variable `key` is not found, returns 1 without
+	touching `value`. The caller should not free or modify `value`, as it
+	is owned by the cache.
+
+`const struct string_list *git_configset_get_value_multi(struct config_set *cs, const char *key)`::
+
+	Finds and returns the value list, sorted in order of increasing priority
+	for the configuration variable `key` and config set `cs`. When the
+	configuration variable `key` is not found, returns NULL. The caller
+	should not free or modify the returned pointer, as it is owned by the cache.
+
+`void git_configset_clear(struct config_set *cs)`::
+
+	Clears `config_set` structure, removes all saved variable-value pairs.
+
+In addition to above functions, the `config_set` API provides type specific
+functions in the vein of `git_config_get_int` and family but with an extra
+parameter, pointer to struct `config_set`.
+They all behave similarly to the `git_config_get*()` family described in
+"Querying For Specific Variables" above.
+
+Writing Config Files
+--------------------
+
+Git gives multiple entry points in the Config API to write config values to
+files namely `git_config_set_in_file` and `git_config_set`, which write to
+a specific config file or to `.git/config` respectively. They both take a
+key/value pair as parameter.
+In the end they both call `git_config_set_multivar_in_file` which takes four
+parameters:
+
+- the name of the file, as a string, to which key/value pairs will be written.
+
+- the name of key, as a string. This is in canonical "flat" form: the section,
+  subsection, and variable segments will be separated by dots, and the section
+  and variable segments will be all lowercase.
+  E.g., `core.ignorecase`, `diff.SomeType.textconv`.
+
+- the value of the variable, as a string. If value is equal to NULL, it will
+  remove the matching key from the config file.
+
+- the value regex, as a string. It will disregard key/value pairs where value
+  does not match.
+
+- a multi_replace value, as an int. If value is equal to zero, nothing or only
+  one matching key/value is replaced, else all matching key/values (regardless
+  how many) are removed, before the new pair is written.
+
+It returns 0 on success.
+
+Also, there are functions `git_config_rename_section` and
+`git_config_rename_section_in_file` with parameters `old_name` and `new_name`
+for renaming or removing sections in the config files. If NULL is passed
+through `new_name` parameter, the section will be removed from the config file.

+credentials API
+===============
+
+The credentials API provides an abstracted way of gathering username and
+password credentials from the user (even though credentials in the wider
+world can take many forms, in this document the word "credential" always
+refers to a username and password pair).
+
+This document describes two interfaces: the C API that the credential
+subsystem provides to the rest of Git, and the protocol that Git uses to
+communicate with system-specific "credential helpers". If you are
+writing Git code that wants to look up or prompt for credentials, see
+the section "C API" below. If you want to write your own helper, see
+the section on "Credential Helpers" below.
+
+Typical setup
+-------------
+
+------------
++-----------------------+
+| Git code (C)          |--- to server requiring --->
+|                       |        authentication
+|.......................|
+| C credential API      |--- prompt ---> User
++-----------------------+
+	^      |
+	| pipe |
+	|      v
++-----------------------+
+| Git credential helper |
++-----------------------+
+------------
+
+The Git code (typically a remote-helper) will call the C API to obtain
+credential data like a login/password pair (credential_fill). The
+API will itself call a remote helper (e.g. "git credential-cache" or
+"git credential-store") that may retrieve credential data from a
+store. If the credential helper cannot find the information, the C API
+will prompt the user. Then, the caller of the API takes care of
+contacting the server, and does the actual authentication.
+
+C API
+-----
+
+The credential C API is meant to be called by Git code which needs to
+acquire or store a credential. It is centered around an object
+representing a single credential and provides three basic operations:
+fill (acquire credentials by calling helpers and/or prompting the user),
+approve (mark a credential as successfully used so that it can be stored
+for later use), and reject (mark a credential as unsuccessful so that it
+can be erased from any persistent storage).
+
+Data Structures
+~~~~~~~~~~~~~~~
+
+`struct credential`::
+
+	This struct represents a single username/password combination
+	along with any associated context. All string fields should be
+	heap-allocated (or NULL if they are not known or not applicable).
+	The meaning of the individual context fields is the same as
+	their counterparts in the helper protocol; see the section below
+	for a description of each field.
++
+The `helpers` member of the struct is a `string_list` of helpers.  Each
+string specifies an external helper which will be run, in order, to
+either acquire or store credentials. See the section on credential
+helpers below. This list is filled-in by the API functions
+according to the corresponding configuration variables before
+consulting helpers, so there usually is no need for a caller to
+modify the helpers field at all.
++
+This struct should always be initialized with `CREDENTIAL_INIT` or
+`credential_init`.
+
+
+Functions
+~~~~~~~~~
+
+`credential_init`::
+
+	Initialize a credential structure, setting all fields to empty.
+
+`credential_clear`::
+
+	Free any resources associated with the credential structure,
+	returning it to a pristine initialized state.
+
+`credential_fill`::
+
+	Instruct the credential subsystem to fill the username and
+	password fields of the passed credential struct by first
+	consulting helpers, then asking the user. After this function
+	returns, the username and password fields of the credential are
+	guaranteed to be non-NULL. If an error occurs, the function will
+	die().
+
+`credential_reject`::
+
+	Inform the credential subsystem that the provided credentials
+	have been rejected. This will cause the credential subsystem to
+	notify any helpers of the rejection (which allows them, for
+	example, to purge the invalid credentials from storage).  It
+	will also free() the username and password fields of the
+	credential and set them to NULL (readying the credential for
+	another call to `credential_fill`). Any errors from helpers are
+	ignored.
+
+`credential_approve`::
+
+	Inform the credential subsystem that the provided credentials
+	were successfully used for authentication.  This will cause the
+	credential subsystem to notify any helpers of the approval, so
+	that they may store the result to be used again.  Any errors
+	from helpers are ignored.
+
+`credential_from_url`::
+
+	Parse a URL into broken-down credential fields.
+
+Example
+~~~~~~~
+
+The example below shows how the functions of the credential API could be
+used to login to a fictitious "foo" service on a remote host:
+
+-----------------------------------------------------------------------
+int foo_login(struct foo_connection *f)
+{
+	int status;
+	/*
+	 * Create a credential with some context; we don't yet know the
+	 * username or password.
+	 */
+
+	struct credential c = CREDENTIAL_INIT;
+	c.protocol = xstrdup("foo");
+	c.host = xstrdup(f->hostname);
+
+	/*
+	 * Fill in the username and password fields by contacting
+	 * helpers and/or asking the user. The function will die if it
+	 * fails.
+	 */
+	credential_fill(&c);
+
+	/*
+	 * Otherwise, we have a username and password. Try to use it.
+	 */
+	status = send_foo_login(f, c.username, c.password);
+	switch (status) {
+	case FOO_OK:
+		/* It worked. Store the credential for later use. */
+		credential_accept(&c);
+		break;
+	case FOO_BAD_LOGIN:
+		/* Erase the credential from storage so we don't try it
+		 * again. */
+		credential_reject(&c);
+		break;
+	default:
+		/*
+		 * Some other error occurred. We don't know if the
+		 * credential is good or bad, so report nothing to the
+		 * credential subsystem.
+		 */
+	}
+
+	/* Free any associated resources. */
+	credential_clear(&c);
+
+	return status;
+}
+-----------------------------------------------------------------------
+
+
+Credential Helpers
+------------------
+
+Credential helpers are programs executed by Git to fetch or save
+credentials from and to long-term storage (where "long-term" is simply
+longer than a single Git process; e.g., credentials may be stored
+in-memory for a few minutes, or indefinitely on disk).
+
+Each helper is specified by a single string in the configuration
+variable `credential.helper` (and others, see linkgit:git-config[1]).
+The string is transformed by Git into a command to be executed using
+these rules:
+
+  1. If the helper string begins with "!", it is considered a shell
+     snippet, and everything after the "!" becomes the command.
+
+  2. Otherwise, if the helper string begins with an absolute path, the
+     verbatim helper string becomes the command.
+
+  3. Otherwise, the string "git credential-" is prepended to the helper
+     string, and the result becomes the command.
+
+The resulting command then has an "operation" argument appended to it
+(see below for details), and the result is executed by the shell.
+
+Here are some example specifications:
+
+----------------------------------------------------
+# run "git credential-foo"
+foo
+
+# same as above, but pass an argument to the helper
+foo --bar=baz
+
+# the arguments are parsed by the shell, so use shell
+# quoting if necessary
+foo --bar="whitespace arg"
+
+# you can also use an absolute path, which will not use the git wrapper
+/path/to/my/helper --with-arguments
+
+# or you can specify your own shell snippet
+!f() { echo "password=`cat $HOME/.secret`"; }; f
+----------------------------------------------------
+
+Generally speaking, rule (3) above is the simplest for users to specify.
+Authors of credential helpers should make an effort to assist their
+users by naming their program "git-credential-$NAME", and putting it in
+the $PATH or $GIT_EXEC_PATH during installation, which will allow a user
+to enable it with `git config credential.helper $NAME`.
+
+When a helper is executed, it will have one "operation" argument
+appended to its command line, which is one of:
+
+`get`::
+
+	Return a matching credential, if any exists.
+
+`store`::
+
+	Store the credential, if applicable to the helper.
+
+`erase`::
+
+	Remove a matching credential, if any, from the helper's storage.
+
+The details of the credential will be provided on the helper's stdin
+stream. The exact format is the same as the input/output format of the
+`git credential` plumbing command (see the section `INPUT/OUTPUT
+FORMAT` in linkgit:git-credential[7] for a detailed specification).
+
+For a `get` operation, the helper should produce a list of attributes
+on stdout in the same format. A helper is free to produce a subset, or
+even no values at all if it has nothing useful to provide. Any provided
+attributes will overwrite those already known about by Git.  If a helper
+outputs a `quit` attribute with a value of `true` or `1`, no further
+helpers will be consulted, nor will the user be prompted (if no
+credential has been provided, the operation will then fail).
+
+For a `store` or `erase` operation, the helper's output is ignored.
+If it fails to perform the requested operation, it may complain to
+stderr to inform the user. If it does not support the requested
+operation (e.g., a read-only store), it should silently ignore the
+request.
+
+If a helper receives any other operation, it should silently ignore the
+request. This leaves room for future operations to be added (older
+helpers will just ignore the new requests).

+diff API
+========
+
+The diff API is for programs that compare two sets of files (e.g. two
+trees, one tree and the index) and present the found difference in
+various ways.  The calling program is responsible for feeding the API
+pairs of files, one from the "old" set and the corresponding one from
+"new" set, that are different.  The library called through this API is
+called diffcore, and is responsible for two things.
+
+* finding total rewrites (`-B`), renames (`-M`) and copies (`-C`), and
+  changes that touch a string (`-S`), as specified by the caller.
+
+* outputting the differences in various formats, as specified by the
+  caller.
+
+Calling sequence
+----------------
+
+* Prepare `struct diff_options` to record the set of diff options, and
+  then call `diff_setup()` to initialize this structure.  This sets up
+  the vanilla default.
+
+* Fill in the options structure to specify desired output format, rename
+  detection, etc.  `diff_opt_parse()` can be used to parse options given
+  from the command line in a way consistent with existing git-diff
+  family of programs.
+
+* Call `diff_setup_done()`; this inspects the options set up so far for
+  internal consistency and make necessary tweaking to it (e.g. if
+  textual patch output was asked, recursive behaviour is turned on);
+  the callback set_default in diff_options can be used to tweak this more.
+
+* As you find different pairs of files, call `diff_change()` to feed
+  modified files, `diff_addremove()` to feed created or deleted files,
+  or `diff_unmerge()` to feed a file whose state is 'unmerged' to the
+  API.  These are thin wrappers to a lower-level `diff_queue()` function
+  that is flexible enough to record any of these kinds of changes.
+
+* Once you finish feeding the pairs of files, call `diffcore_std()`.
+  This will tell the diffcore library to go ahead and do its work.
+
+* Calling `diff_flush()` will produce the output.
+
+
+Data structures
+---------------
+
+* `struct diff_filespec`
+
+This is the internal representation for a single file (blob).  It
+records the blob object name (if known -- for a work tree file it
+typically is a NUL SHA-1), filemode and pathname.  This is what the
+`diff_addremove()`, `diff_change()` and `diff_unmerge()` synthesize and
+feed `diff_queue()` function with.
+
+* `struct diff_filepair`
+
+This records a pair of `struct diff_filespec`; the filespec for a file
+in the "old" set (i.e. preimage) is called `one`, and the filespec for a
+file in the "new" set (i.e. postimage) is called `two`.  A change that
+represents file creation has NULL in `one`, and file deletion has NULL
+in `two`.
+
+A `filepair` starts pointing at `one` and `two` that are from the same
+filename, but `diffcore_std()` can break pairs and match component
+filespecs with other filespecs from a different filepair to form new
+filepair.  This is called 'rename detection'.
+
+* `struct diff_queue`
+
+This is a collection of filepairs.  Notable members are:
+
+`queue`::
+
+	An array of pointers to `struct diff_filepair`.  This
+	dynamically grows as you add filepairs;
+
+`alloc`::
+
+	The allocated size of the `queue` array;
+
+`nr`::
+
+	The number of elements in the `queue` array.
+
+
+* `struct diff_options`
+
+This describes the set of options the calling program wants to affect
+the operation of diffcore library with.
+
+Notable members are:
+
+`output_format`::
+	The output format used when `diff_flush()` is run.
+
+`context`::
+	Number of context lines to generate in patch output.
+
+`break_opt`, `detect_rename`, `rename-score`, `rename_limit`::
+	Affects the way detection logic for complete rewrites, renames
+	and copies.
+
+`abbrev`::
+	Number of hexdigits to abbreviate raw format output to.
+
+`pickaxe`::
+	A constant string (can and typically does contain newlines to
+	look for a block of text, not just a single line) to filter out
+	the filepairs that do not change the number of strings contained
+	in its preimage and postimage of the diff_queue.
+
+`flags`::
+	This is mostly a collection of boolean options that affects the
+	operation, but some do not have anything to do with the diffcore
+	library.
+
+`touched_flags`::
+	Records whether a flag has been changed due to user request
+	(rather than just set/unset by default).
+
+`set_default`::
+	Callback which allows tweaking the options in diff_setup_done().
+
+BINARY, TEXT;;
+	Affects the way how a file that is seemingly binary is treated.
+
+FULL_INDEX;;
+	Tells the patch output format not to use abbreviated object
+	names on the "index" lines.
+
+FIND_COPIES_HARDER;;
+	Tells the diffcore library that the caller is feeding unchanged
+	filepairs to allow copies from unmodified files be detected.
+
+COLOR_DIFF;;
+	Output should be colored.
+
+COLOR_DIFF_WORDS;;
+	Output is a colored word-diff.
+
+NO_INDEX;;
+	Tells diff-files that the input is not tracked files but files
+	in random locations on the filesystem.
+
+ALLOW_EXTERNAL;;
+	Tells output routine that it is Ok to call user specified patch

+directory listing API
+=====================
+
+The directory listing API is used to enumerate paths in the work tree,
+optionally taking `.git/info/exclude` and `.gitignore` files per
+directory into account.
+
+Data structure
+--------------
+
+`struct dir_struct` structure is used to pass directory traversal
+options to the library and to record the paths discovered.  A single
+`struct dir_struct` is used regardless of whether or not the traversal
+recursively descends into subdirectories.
+
+The notable options are:
+
+`exclude_per_dir`::
+
+	The name of the file to be read in each directory for excluded
+	files (typically `.gitignore`).
+
+`flags`::
+
+	A bit-field of options (the `*IGNORED*` flags are mutually exclusive):
+
+`DIR_SHOW_IGNORED`:::
+
+	Return just ignored files in `entries[]`, not untracked files.
+
+`DIR_SHOW_IGNORED_TOO`:::
+
+	Similar to `DIR_SHOW_IGNORED`, but return ignored files in `ignored[]`
+	in addition to untracked files in `entries[]`.
+
+`DIR_COLLECT_IGNORED`:::
+
+	Special mode for git-add. Return ignored files in `ignored[]` and
+	untracked files in `entries[]`. Only returns ignored files that match
+	pathspec exactly (no wildcards). Does not recurse into ignored
+	directories.
+
+`DIR_SHOW_OTHER_DIRECTORIES`:::
+
+	Include a directory that is not tracked.
+
+`DIR_HIDE_EMPTY_DIRECTORIES`:::
+
+	Do not include a directory that is not tracked and is empty.
+
+`DIR_NO_GITLINKS`:::
+
+	If set, recurse into a directory that looks like a Git
+	directory.  Otherwise it is shown as a directory.
+
+The result of the enumeration is left in these fields:
+
+`entries[]`::
+
+	An array of `struct dir_entry`, each element of which describes
+	a path.
+
+`nr`::
+
+	The number of members in `entries[]` array.
+
+`alloc`::
+
+	Internal use; keeps track of allocation of `entries[]` array.
+
+`ignored[]`::
+
+	An array of `struct dir_entry`, used for ignored paths with the
+	`DIR_SHOW_IGNORED_TOO` and `DIR_COLLECT_IGNORED` flags.
+
+`ignored_nr`::
+
+	The number of members in `ignored[]` array.
+
+Calling sequence
+----------------
+
+Note: index may be looked at for .gitignore files that are CE_SKIP_WORKTREE
+marked. If you to exclude files, make sure you have loaded index first.
+
+* Prepare `struct dir_struct dir` and clear it with `memset(&dir, 0,
+  sizeof(dir))`.
+
+* To add single exclude pattern, call `add_exclude_list()` and then
+  `add_exclude()`.
+
+* To add patterns from a file (e.g. `.git/info/exclude`), call
+  `add_excludes_from_file()` , and/or set `dir.exclude_per_dir`.  A
+  short-hand function `setup_standard_excludes()` can be used to set
+  up the standard set of exclude settings.
+
+* Set options described in the Data Structure section above.
+
+* Call `read_directory()`.
+
+* Use `dir.entries[]`.
+
+* Call `clear_directory()` when none of the contained elements are no longer in use.

+Error reporting in git
+======================
+
+`die`, `usage`, `error`, and `warning` report errors of various
+kinds.
+
+- `die` is for fatal application errors.  It prints a message to
+  the user and exits with status 128.
+
+- `usage` is for errors in command line usage.  After printing its
+  message, it exits with status 129.  (See also `usage_with_options`
+  in the link:api-parse-options.html[parse-options API].)
+
+- `error` is for non-fatal library errors.  It prints a message
+  to the user and returns -1 for convenience in signaling the error
+  to the caller.
+
+- `warning` is for reporting situations that probably should not
+  occur but which the user (and Git) can continue to work around
+  without running into too many problems.  Like `error`, it
+  returns -1 after reporting the situation to the caller.
+
+Customizable error handlers
+---------------------------
+
+The default behavior of `die` and `error` is to write a message to
+stderr and then exit or return as appropriate.  This behavior can be
+overridden using `set_die_routine` and `set_error_routine`.  For
+example, "git daemon" uses set_die_routine to write the reason `die`
+was called to syslog before exiting.
+
+Library errors
+--------------
+
+Functions return a negative integer on error.  Details beyond that
+vary from function to function:
+
+- Some functions return -1 for all errors.  Others return a more
+  specific value depending on how the caller might want to react
+  to the error.
+
+- Some functions report the error to stderr with `error`,
+  while others leave that for the caller to do.
+
+- errno is not meaningful on return from most functions (except
+  for thin wrappers for system calls).
+
+Check the function's API documentation to be sure.
+
+Caller-handled errors
+---------------------
+
+An increasing number of functions take a parameter 'struct strbuf *err'.
+On error, such functions append a message about what went wrong to the
+'err' strbuf.  The message is meant to be complete enough to be passed
+to `die` or `error` as-is.  For example:
+
+	if (ref_transaction_commit(transaction, &err))
+		die("%s", err.buf);
+
+The 'err' parameter will be untouched if no error occurred, so multiple
+function calls can be chained:
+
+	t = ref_transaction_begin(&err);
+	if (!t ||
+	    ref_transaction_update(t, "HEAD", ..., &err) ||
+	    ret_transaction_commit(t, &err))
+		die("%s", err.buf);
+
+The 'err' parameter must be a pointer to a valid strbuf.  To silence
+a message, pass a strbuf that is explicitly ignored:
+
+	if (thing_that_can_fail_in_an_ignorable_way(..., &err))
+		/* This failure is okay. */
+		strbuf_reset(&err);

+gitattributes API
+=================
+
+gitattributes mechanism gives a uniform way to associate various
+attributes to set of paths.
+
+
+Data Structure
+--------------
+
+`struct git_attr`::
+
+	An attribute is an opaque object that is identified by its name.
+	Pass the name to `git_attr()` function to obtain the object of
+	this type.  The internal representation of this structure is
+	of no interest to the calling programs.  The name of the
+	attribute can be retrieved by calling `git_attr_name()`.
+
+`struct git_attr_check`::
+
+	This structure represents a set of attributes to check in a call
+	to `git_check_attr()` function, and receives the results.
+
+
+Attribute Values
+----------------
+
+An attribute for a path can be in one of four states: Set, Unset,
+Unspecified or set to a string, and `.value` member of `struct
+git_attr_check` records it.  There are three macros to check these:
+
+`ATTR_TRUE()`::
+
+	Returns true if the attribute is Set for the path.
+
+`ATTR_FALSE()`::
+
+	Returns true if the attribute is Unset for the path.
+
+`ATTR_UNSET()`::
+
+	Returns true if the attribute is Unspecified for the path.
+
+If none of the above returns true, `.value` member points at a string
+value of the attribute for the path.
+
+
+Querying Specific Attributes
+----------------------------
+
+* Prepare an array of `struct git_attr_check` to define the list of
+  attributes you would want to check.  To populate this array, you would
+  need to define necessary attributes by calling `git_attr()` function.
+
+* Call `git_check_attr()` to check the attributes for the path.
+
+* Inspect `git_attr_check` structure to see how each of the attribute in
+  the array is defined for the path.
+
+
+Example
+-------
+
+To see how attributes "crlf" and "indent" are set for different paths.
+
+. Prepare an array of `struct git_attr_check` with two elements (because
+  we are checking two attributes).  Initialize their `attr` member with
+  pointers to `struct git_attr` obtained by calling `git_attr()`:
+
+------------
+static struct git_attr_check check[2];
+static void setup_check(void)
+{
+	if (check[0].attr)
+		return; /* already done */
+	check[0].attr = git_attr("crlf");
+	check[1].attr = git_attr("ident");
+}
+------------
+
+. Call `git_check_attr()` with the prepared array of `struct git_attr_check`:
+
+------------
+	const char *path;
+
+	setup_check();
+	git_check_attr(path, ARRAY_SIZE(check), check);
+------------
+
+. Act on `.value` member of the result, left in `check[]`:
+
+------------
+	const char *value = check[0].value;
+
+	if (ATTR_TRUE(value)) {
+		The attribute is Set, by listing only the name of the
+		attribute in the gitattributes file for the path.
+	} else if (ATTR_FALSE(value)) {
+		The attribute is Unset, by listing the name of the
+		attribute prefixed with a dash - for the path.
+	} else if (ATTR_UNSET(value)) {
+		The attribute is neither set nor unset for the path.
+	} else if (!strcmp(value, "input")) {
+		If none of ATTR_TRUE(), ATTR_FALSE(), or ATTR_UNSET() is
+		true, the value is a string set in the gitattributes
+		file for the path by saying "attr=value".
+	} else if (... other check using value as string ...) {
+		...
+	}
+------------
+
+
+Querying All Attributes
+-----------------------
+
+To get the values of all attributes associated with a file:
+
+* Call `git_all_attrs()`, which returns an array of `git_attr_check`
+  structures.
+
+* Iterate over the `git_attr_check` array to examine the attribute
+  names and values.  The name of the attribute described by a
+  `git_attr_check` object can be retrieved via
+  `git_attr_name(check[i].attr)`.  (Please note that no items will be
+  returned for unset attributes, so `ATTR_UNSET()` will return false
+  for all returned `git_array_check` objects.)
+
+* Free the `git_array_check` array.

+hashmap API
+===========
+
+The hashmap API is a generic implementation of hash-based key-value mappings.
+
+Data Structures
+---------------
+
+`struct hashmap`::
+
+	The hash table structure. Members can be used as follows, but should
+	not be modified directly:
++
+The `size` member keeps track of the total number of entries (0 means the
+hashmap is empty).
++
+`tablesize` is the allocated size of the hash table. A non-0 value indicates
+that the hashmap is initialized. It may also be useful for statistical purposes
+(i.e. `size / tablesize` is the current load factor).
++
+`cmpfn` stores the comparison function specified in `hashmap_init()`. In
+advanced scenarios, it may be useful to change this, e.g. to switch between
+case-sensitive and case-insensitive lookup.
+
+`struct hashmap_entry`::
+
+	An opaque structure representing an entry in the hash table, which must
+	be used as first member of user data structures. Ideally it should be
+	followed by an int-sized member to prevent unused memory on 64-bit
+	systems due to alignment.
++
+The `hash` member is the entry's hash code and the `next` member points to the
+next entry in case of collisions (i.e. if multiple entries map to the same
+bucket).
+
+`struct hashmap_iter`::
+
+	An iterator structure, to be used with hashmap_iter_* functions.
+
+Types
+-----
+
+`int (*hashmap_cmp_fn)(const void *entry, const void *entry_or_key, const void *keydata)`::
+
+	User-supplied function to test two hashmap entries for equality. Shall
+	return 0 if the entries are equal.
++
+This function is always called with non-NULL `entry` / `entry_or_key`
+parameters that have the same hash code. When looking up an entry, the `key`
+and `keydata` parameters to hashmap_get and hashmap_remove are always passed
+as second and third argument, respectively. Otherwise, `keydata` is NULL.
+
+Functions
+---------
+
+`unsigned int strhash(const char *buf)`::
+`unsigned int strihash(const char *buf)`::
+`unsigned int memhash(const void *buf, size_t len)`::
+`unsigned int memihash(const void *buf, size_t len)`::
+
+	Ready-to-use hash functions for strings, using the FNV-1 algorithm (see
+	http://www.isthe.com/chongo/tech/comp/fnv).
++
+`strhash` and `strihash` take 0-terminated strings, while `memhash` and
+`memihash` operate on arbitrary-length memory.
++
+`strihash` and `memihash` are case insensitive versions.
+
+`unsigned int sha1hash(const unsigned char *sha1)`::
+
+	Converts a cryptographic hash (e.g. SHA-1) into an int-sized hash code
+	for use in hash tables. Cryptographic hashes are supposed to have
+	uniform distribution, so in contrast to `memhash()`, this just copies
+	the first `sizeof(int)` bytes without shuffling any bits. Note that
+	the results will be different on big-endian and little-endian
+	platforms, so they should not be stored or transferred over the net.
+
+`void hashmap_init(struct hashmap *map, hashmap_cmp_fn equals_function, size_t initial_size)`::
+
+	Initializes a hashmap structure.
++
+`map` is the hashmap to initialize.
++
+The `equals_function` can be specified to compare two entries for equality.
+If NULL, entries are considered equal if their hash codes are equal.
++
+If the total number of entries is known in advance, the `initial_size`
+parameter may be used to preallocate a sufficiently large table and thus
+prevent expensive resizing. If 0, the table is dynamically resized.
+
+`void hashmap_free(struct hashmap *map, int free_entries)`::
+
+	Frees a hashmap structure and allocated memory.
++
+`map` is the hashmap to free.
++
+If `free_entries` is true, each hashmap_entry in the map is freed as well
+(using stdlib's free()).
+
+`void hashmap_entry_init(void *entry, unsigned int hash)`::
+
+	Initializes a hashmap_entry structure.
++
+`entry` points to the entry to initialize.
++
+`hash` is the hash code of the entry.
+
+`void *hashmap_get(const struct hashmap *map, const void *key, const void *keydata)`::
+
+	Returns the hashmap entry for the specified key, or NULL if not found.
++
+`map` is the hashmap structure.
++
+`key` is a hashmap_entry structure (or user data structure that starts with
+hashmap_entry) that has at least been initialized with the proper hash code
+(via `hashmap_entry_init`).
++
+If an entry with matching hash code is found, `key` and `keydata` are passed
+to `hashmap_cmp_fn` to decide whether the entry matches the key.
+
+`void *hashmap_get_from_hash(const struct hashmap *map, unsigned int hash, const void *keydata)`::
+
+	Returns the hashmap entry for the specified hash code and key data,
+	or NULL if not found.
++
+`map` is the hashmap structure.
++
+`hash` is the hash code of the entry to look up.
++
+If an entry with matching hash code is found, `keydata` is passed to
+`hashmap_cmp_fn` to decide whether the entry matches the key. The
+`entry_or_key` parameter points to a bogus hashmap_entry structure that
+should not be used in the comparison.
+
+`void *hashmap_get_next(const struct hashmap *map, const void *entry)`::
+
+	Returns the next equal hashmap entry, or NULL if not found. This can be
+	used to iterate over duplicate entries (see `hashmap_add`).
++
+`map` is the hashmap structure.
++
+`entry` is the hashmap_entry to start the search from, obtained via a previous
+call to `hashmap_get` or `hashmap_get_next`.
+
+`void hashmap_add(struct hashmap *map, void *entry)`::
+
+	Adds a hashmap entry. This allows to add duplicate entries (i.e.
+	separate values with the same key according to hashmap_cmp_fn).
++
+`map` is the hashmap structure.
++
+`entry` is the entry to add.
+
+`void *hashmap_put(struct hashmap *map, void *entry)`::
+
+	Adds or replaces a hashmap entry. If the hashmap contains duplicate
+	entries equal to the specified entry, only one of them will be replaced.
++
+`map` is the hashmap structure.
++
+`entry` is the entry to add or replace.
++
+Returns the replaced entry, or NULL if not found (i.e. the entry was added).
+
+`void *hashmap_remove(struct hashmap *map, const void *key, const void *keydata)`::
+
+	Removes a hashmap entry matching the specified key. If the hashmap
+	contains duplicate entries equal to the specified key, only one of
+	them will be removed.
++
+`map` is the hashmap structure.
++
+`key` is a hashmap_entry structure (or user data structure that starts with
+hashmap_entry) that has at least been initialized with the proper hash code
+(via `hashmap_entry_init`).
++
+If an entry with matching hash code is found, `key` and `keydata` are
+passed to `hashmap_cmp_fn` to decide whether the entry matches the key.
++
+Returns the removed entry, or NULL if not found.
+
+`void hashmap_iter_init(struct hashmap *map, struct hashmap_iter *iter)`::
+`void *hashmap_iter_next(struct hashmap_iter *iter)`::
+`void *hashmap_iter_first(struct hashmap *map, struct hashmap_iter *iter)`::
+
+	Used to iterate over all entries of a hashmap.
++
+`hashmap_iter_init` initializes a `hashmap_iter` structure.
++
+`hashmap_iter_next` returns the next hashmap_entry, or NULL if there are no
+more entries.
++
+`hashmap_iter_first` is a combination of both (i.e. initializes the iterator
+and returns the first entry, if any).
+
+`const char *strintern(const char *string)`::
+`const void *memintern(const void *data, size_t len)`::
+
+	Returns the unique, interned version of the specified string or data,
+	similar to the `String.intern` API in Java and .NET, respectively.
+	Interned strings remain valid for the entire lifetime of the process.
++
+Can be used as `[x]strdup()` or `xmemdupz` replacement, except that interned
+strings / data must not be modified or freed.
++
+Interned strings are best used for short strings with high probability of
+duplicates.
++
+Uses a hashmap to store the pool of interned strings.
+
+Usage example
+-------------
+
+Here's a simple usage example that maps long keys to double values.
+------------
+struct hashmap map;
+
+struct long2double {
+	struct hashmap_entry ent; /* must be the first member! */
+	long key;
+	double value;
+};
+
+static int long2double_cmp(const struct long2double *e1, const struct long2double *e2, const void *unused)
+{
+	return !(e1->key == e2->key);
+}
+
+void long2double_init(void)
+{
+	hashmap_init(&map, (hashmap_cmp_fn) long2double_cmp, 0);
+}
+
+void long2double_free(void)
+{
+	hashmap_free(&map, 1);
+}
+
+static struct long2double *find_entry(long key)
+{
+	struct long2double k;
+	hashmap_entry_init(&k, memhash(&key, sizeof(long)));
+	k.key = key;
+	return hashmap_get(&map, &k, NULL);
+}
+
+double get_value(long key)
+{
+	struct long2double *e = find_entry(key);
+	return e ? e->value : 0;
+}
+
+void set_value(long key, double value)
+{
+	struct long2double *e = find_entry(key);
+	if (!e) {
+		e = malloc(sizeof(struct long2double));
+		hashmap_entry_init(e, memhash(&key, sizeof(long)));
+		e->key = key;
+		hashmap_add(&map, e);
+	}
+	e->value = value;
+}
+------------
+
+Using variable-sized keys
+-------------------------
+
+The `hashmap_entry_get` and `hashmap_entry_remove` functions expect an ordinary
+`hashmap_entry` structure as key to find the correct entry. If the key data is
+variable-sized (e.g. a FLEX_ARRAY string) or quite large, it is undesirable
+to create a full-fledged entry structure on the heap and copy all the key data
+into the structure.
+
+In this case, the `keydata` parameter can be used to pass
+variable-sized key data directly to the comparison function, and the `key`
+parameter can be a stripped-down, fixed size entry structure allocated on the
+stack.
+
+See test-hashmap.c for an example using arbitrary-length strings as keys.

+history graph API
+=================
+
+The graph API is used to draw a text-based representation of the commit
+history.  The API generates the graph in a line-by-line fashion.
+
+Functions
+---------
+
+Core functions:
+
+* `graph_init()` creates a new `struct git_graph`
+
+* `graph_update()` moves the graph to a new commit.
+
+* `graph_next_line()` outputs the next line of the graph into a strbuf.  It
+  does not add a terminating newline.
+
+* `graph_padding_line()` outputs a line of vertical padding in the graph.  It
+  is similar to `graph_next_line()`, but is guaranteed to never print the line
+  containing the current commit.  Where `graph_next_line()` would print the
+  commit line next, `graph_padding_line()` prints a line that simply extends
+  all branch lines downwards one row, leaving their positions unchanged.
+
+* `graph_is_commit_finished()` determines if the graph has output all lines
+  necessary for the current commit.  If `graph_update()` is called before all
+  lines for the current commit have been printed, the next call to
+  `graph_next_line()` will output an ellipsis, to indicate that a portion of
+  the graph was omitted.
+
+The following utility functions are wrappers around `graph_next_line()` and
+`graph_is_commit_finished()`.  They always print the output to stdout.
+They can all be called with a NULL graph argument, in which case no graph
+output will be printed.
+
+* `graph_show_commit()` calls `graph_next_line()` and
+  `graph_is_commit_finished()` until one of them return non-zero.  This prints
+  all graph lines up to, and including, the line containing this commit.
+  Output is printed to stdout.  The last line printed does not contain a
+  terminating newline.
+
+* `graph_show_oneline()` calls `graph_next_line()` and prints the result to
+  stdout.  The line printed does not contain a terminating newline.
+
+* `graph_show_padding()` calls `graph_padding_line()` and prints the result to
+  stdout.  The line printed does not contain a terminating newline.
+
+* `graph_show_remainder()` calls `graph_next_line()` until
+  `graph_is_commit_finished()` returns non-zero.  Output is printed to stdout.
+  The last line printed does not contain a terminating newline.  Returns 1 if
+  output was printed, and 0 if no output was necessary.
+
+* `graph_show_strbuf()` prints the specified strbuf to stdout, prefixing all
+  lines but the first with a graph line.  The caller is responsible for
+  ensuring graph output for the first line has already been printed to stdout.
+  (This can be done with `graph_show_commit()` or `graph_show_oneline()`.)  If
+  a NULL graph is supplied, the strbuf is printed as-is.
+
+* `graph_show_commit_msg()` is similar to `graph_show_strbuf()`, but it also
+  prints the remainder of the graph, if more lines are needed after the strbuf
+  ends.  It is better than directly calling `graph_show_strbuf()` followed by
+  `graph_show_remainder()` since it properly handles buffers that do not end in
+  a terminating newline.  The output printed by `graph_show_commit_msg()` will
+  end in a newline if and only if the strbuf ends in a newline.
+
+Data structure
+--------------
+`struct git_graph` is an opaque data type used to store the current graph
+state.
+
+Calling sequence
+----------------
+
+* Create a `struct git_graph` by calling `graph_init()`.  When using the
+  revision walking API, this is done automatically by `setup_revisions()` if
+  the '--graph' option is supplied.
+
+* Use the revision walking API to walk through a group of contiguous commits.
+  The `get_revision()` function automatically calls `graph_update()` each time
+  it is invoked.
+
+* For each commit, call `graph_next_line()` repeatedly, until
+  `graph_is_commit_finished()` returns non-zero.  Each call go
+  `graph_next_line()` will output a single line of the graph.  The resulting
+  lines will not contain any newlines.  `graph_next_line()` returns 1 if the
+  resulting line contains the current commit, or 0 if this is merely a line
+  needed to adjust the graph before or after the current commit.  This return
+  value can be used to determine where to print the commit summary information
+  alongside the graph output.
+
+Limitations
+-----------
+
+* `graph_update()` must be called with commits in topological order.  It should
+  not be called on a commit if it has already been invoked with an ancestor of
+  that commit, or the graph output will be incorrect.
+
+* `graph_update()` must be called on a contiguous group of commits.  If
+  `graph_update()` is called on a particular commit, it should later be called
+  on all parents of that commit.  Parents must not be skipped, or the graph
+  output will appear incorrect.
++
+`graph_update()` may be used on a pruned set of commits only if the parent list
+has been rewritten so as to include only ancestors from the pruned set.
+
+* The graph API does not currently support reverse commit ordering.  In
+  order to implement reverse ordering, the graphing API needs an
+  (efficient) mechanism to find the children of a commit.
+
+Sample usage
+------------
+
+------------
+struct commit *commit;
+struct git_graph *graph = graph_init(opts);
+
+while ((commit = get_revision(opts)) != NULL) {
+	graph_update(graph, commit);
+	while (!graph_is_commit_finished(graph))
+	{
+		struct strbuf sb;
+		int is_commit_line;
+
+		strbuf_init(&sb, 0);
+		is_commit_line = graph_next_line(graph, &sb);
+		fputs(sb.buf, stdout);
+
+		if (is_commit_line)
+			log_tree_commit(opts, commit);
+		else
+			putchar(opts->diffopt.line_termination);
+	}
+}
+------------
+
+Sample output
+-------------
+
+The following is an example of the output from the graph API.  This output does
+not include any commit summary information--callers are responsible for
+outputting that information, if desired.

+merge API
+=========
+
+The merge API helps a program to reconcile two competing sets of
+improvements to some files (e.g., unregistered changes from the work
+tree versus changes involved in switching to a new branch), reporting
+conflicts if found.  The library called through this API is
+responsible for a few things.
+
+ * determining which trees to merge (recursive ancestor consolidation);
+
+ * lining up corresponding files in the trees to be merged (rename
+   detection, subtree shifting), reporting edge cases like add/add
+   and rename/rename conflicts to the user;
+
+ * performing a three-way merge of corresponding files, taking
+   path-specific merge drivers (specified in `.gitattributes`)
+   into account.
+
+Data structures
+---------------
+
+* `mmbuffer_t`, `mmfile_t`
+
+These store data usable for use by the xdiff backend, for writing and
+for reading, respectively.  See `xdiff/xdiff.h` for the definitions
+and `diff.c` for examples.
+
+* `struct ll_merge_options`
+
+This describes the set of options the calling program wants to affect
+the operation of a low-level (single file) merge.  Some options:
+
+`virtual_ancestor`::
+	Behave as though this were part of a merge between common
+	ancestors in a recursive merge.
+	If a helper program is specified by the
+	`[merge "<driver>"] recursive` configuration, it will
+	be used (see linkgit:gitattributes[5]).
+
+`variant`::
+	Resolve local conflicts automatically in favor
+	of one side or the other (as in 'git merge-file'
+	`--ours`/`--theirs`/`--union`).  Can be `0`,
+	`XDL_MERGE_FAVOR_OURS`, `XDL_MERGE_FAVOR_THEIRS`, or
+	`XDL_MERGE_FAVOR_UNION`.
+
+`renormalize`::
+	Resmudge and clean the "base", "theirs" and "ours" files
+	before merging.  Use this when the merge is likely to have
+	overlapped with a change in smudge/clean or end-of-line
+	normalization rules.
+
+Low-level (single file) merge
+-----------------------------
+
+`ll_merge`::
+
+	Perform a three-way single-file merge in core.  This is
+	a thin wrapper around `xdl_merge` that takes the path and
+	any merge backend specified in `.gitattributes` or
+	`.git/info/attributes` into account.  Returns 0 for a
+	clean merge.
+
+Calling sequence:
+
+* Prepare a `struct ll_merge_options` to record options.
+  If you have no special requests, skip this and pass `NULL`
+  as the `opts` parameter to use the default options.
+
+* Allocate an mmbuffer_t variable for the result.
+
+* Allocate and fill variables with the file's original content
+  and two modified versions (using `read_mmfile`, for example).
+
+* Call `ll_merge()`.
+
+* Read the merged content from `result_buf.ptr` and `result_buf.size`.
+
+* Release buffers when finished.  A simple
+  `free(ancestor.ptr); free(ours.ptr); free(theirs.ptr);
+  free(result_buf.ptr);` will do.
+
+If the modifications do not merge cleanly, `ll_merge` will return a
+nonzero value and `result_buf` will generally include a description of
+the conflict bracketed by markers such as the traditional `<<<<<<<`
+and `>>>>>>>`.
+
+The `ancestor_label`, `our_label`, and `their_label` parameters are
+used to label the different sides of a conflict if the merge driver
+supports this.
+
+Everything else
+---------------
+
+Talk about <merge-recursive.h> and merge_file():
+
+ - merge_trees() to merge with rename detection
+ - merge_recursive() for ancestor consolidation
+ - try_merge_command() for other strategies
+ - conflict format
+ - merge options

+parse-options API
+=================
+
+The parse-options API is used to parse and massage options in Git
+and to provide a usage help with consistent look.
+
+Basics
+------
+
+The argument vector `argv[]` may usually contain mandatory or optional
+'non-option arguments', e.g. a filename or a branch, and 'options'.
+Options are optional arguments that start with a dash and
+that allow to change the behavior of a command.
+
+* There are basically three types of options:
+  'boolean' options,
+  options with (mandatory) 'arguments' and
+  options with 'optional arguments'
+  (i.e. a boolean option that can be adjusted).
+
+* There are basically two forms of options:
+  'Short options' consist of one dash (`-`) and one alphanumeric
+  character.
+  'Long options' begin with two dashes (`--`) and some
+  alphanumeric characters.
+
+* Options are case-sensitive.
+  Please define 'lower-case long options' only.
+
+The parse-options API allows:
+
+* 'stuck' and 'separate form' of options with arguments.
+  `-oArg` is stuck, `-o Arg` is separate form.
+  `--option=Arg` is stuck, `--option Arg` is separate form.
+
+* Long options may be 'abbreviated', as long as the abbreviation
+  is unambiguous.
+
+* Short options may be bundled, e.g. `-a -b` can be specified as `-ab`.
+
+* Boolean long options can be 'negated' (or 'unset') by prepending
+  `no-`, e.g. `--no-abbrev` instead of `--abbrev`. Conversely,
+  options that begin with `no-` can be 'negated' by removing it.
+  Other long options can be unset (e.g., set string to NULL, set
+  integer to 0) by prepending `no-`.
+
+* Options and non-option arguments can clearly be separated using the `--`
+  option, e.g. `-a -b --option -- --this-is-a-file` indicates that
+  `--this-is-a-file` must not be processed as an option.
+
+Steps to parse options
+----------------------
+
+. `#include "parse-options.h"`
+
+. define a NULL-terminated
+  `static const char * const builtin_foo_usage[]` array
+  containing alternative usage strings
+
+. define `builtin_foo_options` array as described below
+  in section 'Data Structure'.
+
+. in `cmd_foo(int argc, const char **argv, const char *prefix)`
+  call
+
+	argc = parse_options(argc, argv, prefix, builtin_foo_options, builtin_foo_usage, flags);
++
+`parse_options()` will filter out the processed options of `argv[]` and leave the
+non-option arguments in `argv[]`.
+`argc` is updated appropriately because of the assignment.
++
+You can also pass NULL instead of a usage array as the fifth parameter of
+parse_options(), to avoid displaying a help screen with usage info and
+option list.  This should only be done if necessary, e.g. to implement
+a limited parser for only a subset of the options that needs to be run
+before the full parser, which in turn shows the full help message.
++
+Flags are the bitwise-or of:
+
+`PARSE_OPT_KEEP_DASHDASH`::
+	Keep the `--` that usually separates options from
+	non-option arguments.
+
+`PARSE_OPT_STOP_AT_NON_OPTION`::
+	Usually the whole argument vector is massaged and reordered.
+	Using this flag, processing is stopped at the first non-option
+	argument.
+
+`PARSE_OPT_KEEP_ARGV0`::
+	Keep the first argument, which contains the program name.  It's
+	removed from argv[] by default.
+
+`PARSE_OPT_KEEP_UNKNOWN`::
+	Keep unknown arguments instead of erroring out.  This doesn't
+	work for all combinations of arguments as users might expect
+	it to do.  E.g. if the first argument in `--unknown --known`
+	takes a value (which we can't know), the second one is
+	mistakenly interpreted as a known option.  Similarly, if
+	`PARSE_OPT_STOP_AT_NON_OPTION` is set, the second argument in
+	`--unknown value` will be mistakenly interpreted as a
+	non-option, not as a value belonging to the unknown option,
+	the parser early.  That's why parse_options() errors out if
+	both options are set.
+
+`PARSE_OPT_NO_INTERNAL_HELP`::
+	By default, parse_options() handles `-h`, `--help` and
+	`--help-all` internally, by showing a help screen.  This option
+	turns it off and allows one to add custom handlers for these
+	options, or to just leave them unknown.
+
+Data Structure
+--------------
+
+The main data structure is an array of the `option` struct,
+say `static struct option builtin_add_options[]`.
+There are some macros to easily define options:
+
+`OPT__ABBREV(&int_var)`::
+	Add `--abbrev[=<n>]`.
+
+`OPT__COLOR(&int_var, description)`::
+	Add `--color[=<when>]` and `--no-color`.
+
+`OPT__DRY_RUN(&int_var, description)`::
+	Add `-n, --dry-run`.
+
+`OPT__FORCE(&int_var, description)`::
+	Add `-f, --force`.
+
+`OPT__QUIET(&int_var, description)`::
+	Add `-q, --quiet`.
+
+`OPT__VERBOSE(&int_var, description)`::
+	Add `-v, --verbose`.
+
+`OPT_GROUP(description)`::
+	Start an option group. `description` is a short string that
+	describes the group or an empty string.
+	Start the description with an upper-case letter.
+
+`OPT_BOOL(short, long, &int_var, description)`::
+	Introduce a boolean option. `int_var` is set to one with
+	`--option` and set to zero with `--no-option`.
+
+`OPT_COUNTUP(short, long, &int_var, description)`::
+	Introduce a count-up option.
+	`int_var` is incremented on each use of `--option`, and
+	reset to zero with `--no-option`.
+
+`OPT_BIT(short, long, &int_var, description, mask)`::
+	Introduce a boolean option.
+	If used, `int_var` is bitwise-ored with `mask`.
+
+`OPT_NEGBIT(short, long, &int_var, description, mask)`::
+	Introduce a boolean option.
+	If used, `int_var` is bitwise-anded with the inverted `mask`.
+
+`OPT_SET_INT(short, long, &int_var, description, integer)`::
+	Introduce an integer option.
+	`int_var` is set to `integer` with `--option`, and
+	reset to zero with `--no-option`.
+
+`OPT_STRING(short, long, &str_var, arg_str, description)`::
+	Introduce an option with string argument.
+	The string argument is put into `str_var`.
+
+`OPT_INTEGER(short, long, &int_var, description)`::
+	Introduce an option with integer argument.
+	The integer is put into `int_var`.
+
+`OPT_MAGNITUDE(short, long, &unsigned_long_var, description)`::
+	Introduce an option with a size argument. The argument must be a
+	non-negative integer and may include a suffix of 'k', 'm' or 'g' to
+	scale the provided value by 1024, 1024^2 or 1024^3 respectively.
+	The scaled value is put into `unsigned_long_var`.
+
+`OPT_DATE(short, long, &int_var, description)`::
+	Introduce an option with date argument, see `approxidate()`.
+	The timestamp is put into `int_var`.
+
+`OPT_EXPIRY_DATE(short, long, &int_var, description)`::
+	Introduce an option with expiry date argument, see `parse_expiry_date()`.
+	The timestamp is put into `int_var`.
+
+`OPT_CALLBACK(short, long, &var, arg_str, description, func_ptr)`::
+	Introduce an option with argument.
+	The argument will be fed into the function given by `func_ptr`
+	and the result will be put into `var`.
+	See 'Option Callbacks' below for a more elaborate description.
+
+`OPT_FILENAME(short, long, &var, description)`::
+	Introduce an option with a filename argument.
+	The filename will be prefixed by passing the filename along with
+	the prefix argument of `parse_options()` to `prefix_filename()`.
+
+`OPT_ARGUMENT(long, description)`::
+	Introduce a long-option argument that will be kept in `argv[]`.
+
+`OPT_NUMBER_CALLBACK(&var, description, func_ptr)`::
+	Recognize numerical options like -123 and feed the integer as
+	if it was an argument to the function given by `func_ptr`.
+	The result will be put into `var`.  There can be only one such
+	option definition.  It cannot be negated and it takes no
+	arguments.  Short options that happen to be digits take
+	precedence over it.
+
+`OPT_COLOR_FLAG(short, long, &int_var, description)`::
+	Introduce an option that takes an optional argument that can
+	have one of three values: "always", "never", or "auto".  If the
+	argument is not given, it defaults to "always".  The `--no-` form
+	works like `--long=never`; it cannot take an argument.  If
+	"always", set `int_var` to 1; if "never", set `int_var` to 0; if
+	"auto", set `int_var` to 1 if stdout is a tty or a pager,
+	0 otherwise.
+
+`OPT_NOOP_NOARG(short, long)`::
+	Introduce an option that has no effect and takes no arguments.
+	Use it to hide deprecated options that are still to be recognized
+	and ignored silently.
+
+`OPT_PASSTHRU(short, long, &char_var, arg_str, description, flags)`::
+	Introduce an option that will be reconstructed into a char* string,
+	which must be initialized to NULL. This is useful when you need to
+	pass the command-line option to another command. Any previous value
+	will be overwritten, so this should only be used for options where
+	the last one specified on the command line wins.
+
+`OPT_PASSTHRU_ARGV(short, long, &argv_array_var, arg_str, description, flags)`::
+	Introduce an option where all instances of it on the command-line will
+	be reconstructed into an argv_array. This is useful when you need to
+	pass the command-line option, which can be specified multiple times,
+	to another command.
+
+
+The last element of the array must be `OPT_END()`.
+
+If not stated otherwise, interpret the arguments as follows:
+
+* `short` is a character for the short option
+  (e.g. `'e'` for `-e`, use `0` to omit),
+
+* `long` is a string for the long option
+  (e.g. `"example"` for `--example`, use `NULL` to omit),
+
+* `int_var` is an integer variable,
+
+* `str_var` is a string variable (`char *`),
+
+* `arg_str` is the string that is shown as argument
+  (e.g. `"branch"` will result in `<branch>`).
+  If set to `NULL`, three dots (`...`) will be displayed.
+
+* `description` is a short string to describe the effect of the option.
+  It shall begin with a lower-case letter and a full stop (`.`) shall be
+  omitted at the end.
+
+Option Callbacks
+----------------
+
+The function must be defined in this form:
+
+	int func(const struct option *opt, const char *arg, int unset)
+
+The callback mechanism is as follows:
+
+* Inside `func`, the only interesting member of the structure
+  given by `opt` is the void pointer `opt->value`.
+  `*opt->value` will be the value that is saved into `var`, if you
+  use `OPT_CALLBACK()`.
+  For example, do `*(unsigned long *)opt->value = 42;` to get 42
+  into an `unsigned long` variable.
+
+* Return value `0` indicates success and non-zero return
+  value will invoke `usage_with_options()` and, thus, die.
+
+* If the user negates the option, `arg` is `NULL` and `unset` is 1.
+
+Sophisticated option parsing
+----------------------------
+
+If you need, for example, option callbacks with optional arguments
+or without arguments at all, or if you need other special cases,
+that are not handled by the macros above, you need to specify the
+members of the `option` structure manually.
+
+This is not covered in this document, but well documented
+in `parse-options.h` itself.
+
+Examples
+--------
+
+See `test-parse-options.c` and
+`builtin/add.c`,
+`builtin/clone.c`,
+`builtin/commit.c`,
+`builtin/fetch.c`,
+`builtin/fsck.c`,
+`builtin/rm.c`
+for real-world examples.

+ref iteration API
+=================
+
+
+Iteration of refs is done by using an iterate function which will call a
+callback function for every ref. The callback function has this
+signature:
+
+	int handle_one_ref(const char *refname, const struct object_id *oid,
+			   int flags, void *cb_data);
+
+There are different kinds of iterate functions which all take a
+callback of this type. The callback is then called for each found ref
+until the callback returns nonzero. The returned value is then also
+returned by the iterate function.
+
+Iteration functions
+-------------------
+
+* `head_ref()` just iterates the head ref.
+
+* `for_each_ref()` iterates all refs.
+
+* `for_each_ref_in()` iterates all refs which have a defined prefix and
+  strips that prefix from the passed variable refname.
+
+* `for_each_tag_ref()`, `for_each_branch_ref()`, `for_each_remote_ref()`,
+  `for_each_replace_ref()` iterate refs from the respective area.
+
+* `for_each_glob_ref()` iterates all refs that match the specified glob
+  pattern.
+
+* `for_each_glob_ref_in()` the previous and `for_each_ref_in()` combined.
+
+* `head_ref_submodule()`, `for_each_ref_submodule()`,
+  `for_each_ref_in_submodule()`, `for_each_tag_ref_submodule()`,
+  `for_each_branch_ref_submodule()`, `for_each_remote_ref_submodule()`
+  do the same as the functions described above but for a specified
+  submodule.
+
+* `for_each_rawref()` can be used to learn about broken ref and symref.
+
+* `for_each_reflog()` iterates each reflog file.
+
+Submodules
+----------
+
+If you want to iterate the refs of a submodule you first need to add the
+submodules object database. You can do this by a code-snippet like
+this:
+
+	const char *path = "path/to/submodule"
+	if (add_submodule_odb(path))
+		die("Error submodule '%s' not populated.", path);
+
+`add_submodule_odb()` will return zero on success. If you
+do not do this you will get an error for each ref that it does not point
+to a valid object.
+
+Note: As a side-effect of this you can not safely assume that all
+objects you lookup are available in superproject. All submodule objects
+will be available the same way as the superprojects objects.
+
+Example:
+--------
+
+----
+static int handle_remote_ref(const char *refname,
+		const unsigned char *sha1, int flags, void *cb_data)
+{
+	struct strbuf *output = cb_data;
+	strbuf_addf(output, "%s\n", refname);
+	return 0;
+}
+
+...
+
+	struct strbuf output = STRBUF_INIT;
+	for_each_remote_ref(handle_remote_ref, &output);
+	printf("%s", output.buf);

+Remotes configuration API
+=========================
+
+The API in remote.h gives access to the configuration related to
+remotes. It handles all three configuration mechanisms historically
+and currently used by Git, and presents the information in a uniform
+fashion. Note that the code also handles plain URLs without any
+configuration, giving them just the default information.
+
+struct remote
+-------------
+
+`name`::
+
+	The user's nickname for the remote
+
+`url`::
+
+	An array of all of the url_nr URLs configured for the remote
+
+`pushurl`::
+
+	An array of all of the pushurl_nr push URLs configured for the remote
+
+`push`::
+
+	 An array of refspecs configured for pushing, with
+	 push_refspec being the literal strings, and push_refspec_nr
+	 being the quantity.
+
+`fetch`::
+
+	An array of refspecs configured for fetching, with
+	fetch_refspec being the literal strings, and fetch_refspec_nr
+	being the quantity.
+
+`fetch_tags`::
+
+	The setting for whether to fetch tags (as a separate rule from
+	the configured refspecs); -1 means never to fetch tags, 0
+	means to auto-follow tags based on the default heuristic, 1
+	means to always auto-follow tags, and 2 means to fetch all
+	tags.
+
+`receivepack`, `uploadpack`::
+
+	The configured helper programs to run on the remote side, for
+	Git-native protocols.
+
+`http_proxy`::
+
+	The proxy to use for curl (http, https, ftp, etc.) URLs.
+
+struct remotes can be found by name with remote_get(), and iterated
+through with for_each_remote(). remote_get(NULL) will return the
+default remote, given the current branch and configuration.
+
+struct refspec
+--------------
+
+A struct refspec holds the parsed interpretation of a refspec.  If it
+will force updates (starts with a '+'), force is true.  If it is a
+pattern (sides end with '*') pattern is true.  src and dest are the
+two sides (including '*' characters if present); if there is only one
+side, it is src, and dst is NULL; if sides exist but are empty (i.e.,
+the refspec either starts or ends with ':'), the corresponding side is
+"".
+
+An array of strings can be parsed into an array of struct refspecs
+using parse_fetch_refspec() or parse_push_refspec().
+
+remote_find_tracking(), given a remote and a struct refspec with
+either src or dst filled out, will fill out the other such that the
+result is in the "fetch" specification for the remote (note that this
+evaluates patterns and returns a single result).
+
+struct branch
+-------------
+
+Note that this may end up moving to branch.h
+
+struct branch holds the configuration for a branch. It can be looked
+up with branch_get(name) for "refs/heads/{name}", or with
+branch_get(NULL) for HEAD.
+
+It contains:
+
+`name`::
+
+	The short name of the branch.
+
+`refname`::
+
+	The full path for the branch ref.
+
+`remote_name`::
+
+	The name of the remote listed in the configuration.
+
+`merge_name`::
+
+	An array of the "merge" lines in the configuration.
+
+`merge`::
+
+	An array of the struct refspecs used for the merge lines. That
+	is, merge[i]->dst is a local tracking ref which should be
+	merged into this branch by default.
+
+`merge_nr`::
+
+	The number of merge configurations
+
+branch_has_merge_config() returns true if the given branch has merge
+configuration given.
+
+Other stuff
+-----------
+
+There is other stuff in remote.h that is related, in general, to the
+process of interacting with remotes.

+revision walking API
+====================
+
+The revision walking API offers functions to build a list of revisions
+and then iterate over that list.
+
+Calling sequence
+----------------
+
+The walking API has a given calling sequence: first you need to
+initialize a rev_info structure, then add revisions to control what kind
+of revision list do you want to get, finally you can iterate over the
+revision list.
+
+Functions
+---------
+
+`init_revisions`::
+
+	Initialize a rev_info structure with default values. The second
+	parameter may be NULL or can be prefix path, and then the `.prefix`
+	variable will be set to it. This is typically the first function you
+	want to call when you want to deal with a revision list. After calling
+	this function, you are free to customize options, like set
+	`.ignore_merges` to 0 if you don't want to ignore merges, and so on. See
+	`revision.h` for a complete list of available options.
+
+`add_pending_object`::
+
+	This function can be used if you want to add commit objects as revision
+	information. You can use the `UNINTERESTING` object flag to indicate if
+	you want to include or exclude the given commit (and commits reachable
+	from the given commit) from the revision list.
++
+NOTE: If you have the commits as a string list then you probably want to
+use setup_revisions(), instead of parsing each string and using this
+function.
+
+`setup_revisions`::
+
+	Parse revision information, filling in the `rev_info` structure, and
+	removing the used arguments from the argument list. Returns the number
+	of arguments left that weren't recognized, which are also moved to the
+	head of the argument list. The last parameter is used in case no
+	parameter given by the first two arguments.
+
+`prepare_revision_walk`::
+
+	Prepares the rev_info structure for a walk. You should check if it
+	returns any error (non-zero return code) and if it does not, you can
+	start using get_revision() to do the iteration.
+
+`get_revision`::
+
+	Takes a pointer to a `rev_info` structure and iterates over it,
+	returning a `struct commit *` each time you call it. The end of the
+	revision list is indicated by returning a NULL pointer.
+
+`reset_revision_walk`::
+
+	Reset the flags used by the revision walking api. You can use
+	this to do multiple sequential revision walks.
+
+Data structures
+---------------
+
+Talk about <revision.h>, things like:
+
+* two diff_options, one for path limiting, another for output;
+* remaining functions;

+run-command API
+===============
+
+The run-command API offers a versatile tool to run sub-processes with
+redirected input and output as well as with a modified environment
+and an alternate current directory.
+
+A similar API offers the capability to run a function asynchronously,
+which is primarily used to capture the output that the function
+produces in the caller in order to process it.
+
+
+Functions
+---------
+
+`child_process_init`::
+
+	Initialize a struct child_process variable.
+
+`start_command`::
+
+	Start a sub-process. Takes a pointer to a `struct child_process`
+	that specifies the details and returns pipe FDs (if requested).
+	See below for details.
+
+`finish_command`::
+
+	Wait for the completion of a sub-process that was started with
+	start_command().
+
+`run_command`::
+
+	A convenience function that encapsulates a sequence of
+	start_command() followed by finish_command(). Takes a pointer
+	to a `struct child_process` that specifies the details.
+
+`run_command_v_opt`, `run_command_v_opt_cd_env`::
+
+	Convenience functions that encapsulate a sequence of
+	start_command() followed by finish_command(). The argument argv
+	specifies the program and its arguments. The argument opt is zero
+	or more of the flags `RUN_COMMAND_NO_STDIN`, `RUN_GIT_CMD`,
+	`RUN_COMMAND_STDOUT_TO_STDERR`, or `RUN_SILENT_EXEC_FAILURE`
+	that correspond to the members .no_stdin, .git_cmd,
+	.stdout_to_stderr, .silent_exec_failure of `struct child_process`.
+	The argument dir corresponds the member .dir. The argument env
+	corresponds to the member .env.
+
+The functions above do the following:
+
+. If a system call failed, errno is set and -1 is returned. A diagnostic
+  is printed.
+
+. If the program was not found, then -1 is returned and errno is set to
+  ENOENT; a diagnostic is printed only if .silent_exec_failure is 0.
+
+. Otherwise, the program is run. If it terminates regularly, its exit
+  code is returned. No diagnostic is printed, even if the exit code is
+  non-zero.
+
+. If the program terminated due to a signal, then the return value is the
+  signal number + 128, ie. the same value that a POSIX shell's $? would
+  report.  A diagnostic is printed.
+
+
+`start_async`::
+
+	Run a function asynchronously. Takes a pointer to a `struct
+	async` that specifies the details and returns a set of pipe FDs
+	for communication with the function. See below for details.
+
+`finish_async`::
+
+	Wait for the completion of an asynchronous function that was
+	started with start_async().
+
+`run_hook`::
+
+	Run a hook.
+	The first argument is a pathname to an index file, or NULL
+	if the hook uses the default index file or no index is needed.
+	The second argument is the name of the hook.
+	The further arguments correspond to the hook arguments.
+	The last argument has to be NULL to terminate the arguments list.
+	If the hook does not exist or is not executable, the return
+	value will be zero.
+	If it is executable, the hook will be executed and the exit
+	status of the hook is returned.
+	On execution, .stdout_to_stderr and .no_stdin will be set.
+	(See below.)
+
+
+Data structures
+---------------
+
+* `struct child_process`
+
+This describes the arguments, redirections, and environment of a
+command to run in a sub-process.
+
+The caller:
+
+1. allocates and clears (using child_process_init() or
+   CHILD_PROCESS_INIT) a struct child_process variable;
+2. initializes the members;
+3. calls start_command();
+4. processes the data;
+5. closes file descriptors (if necessary; see below);
+6. calls finish_command().
+
+The .argv member is set up as an array of string pointers (NULL
+terminated), of which .argv[0] is the program name to run (usually
+without a path). If the command to run is a git command, set argv[0] to
+the command name without the 'git-' prefix and set .git_cmd = 1.
+
+Note that the ownership of the memory pointed to by .argv stays with the
+caller, but it should survive until `finish_command` completes. If the
+.argv member is NULL, `start_command` will point it at the .args
+`argv_array` (so you may use one or the other, but you must use exactly
+one). The memory in .args will be cleaned up automatically during
+`finish_command` (or during `start_command` when it is unsuccessful).
+
+The members .in, .out, .err are used to redirect stdin, stdout,
+stderr as follows:
+
+. Specify 0 to request no special redirection. No new file descriptor
+  is allocated. The child process simply inherits the channel from the
+  parent.
+
+. Specify -1 to have a pipe allocated; start_command() replaces -1
+  by the pipe FD in the following way:
+
+	.in: Returns the writable pipe end into which the caller writes;
+		the readable end of the pipe becomes the child's stdin.
+
+	.out, .err: Returns the readable pipe end from which the caller
+		reads; the writable end of the pipe end becomes child's
+		stdout/stderr.
+
+  The caller of start_command() must close the so returned FDs
+  after it has completed reading from/writing to it!
+
+. Specify a file descriptor > 0 to be used by the child:
+
+	.in: The FD must be readable; it becomes child's stdin.
+	.out: The FD must be writable; it becomes child's stdout.
+	.err: The FD must be writable; it becomes child's stderr.
+
+  The specified FD is closed by start_command(), even if it fails to
+  run the sub-process!
+
+. Special forms of redirection are available by setting these members
+  to 1:
+
+	.no_stdin, .no_stdout, .no_stderr: The respective channel is
+		redirected to /dev/null.
+
+	.stdout_to_stderr: stdout of the child is redirected to its
+		stderr. This happens after stderr is itself redirected.
+		So stdout will follow stderr to wherever it is
+		redirected.
+
+To modify the environment of the sub-process, specify an array of
+string pointers (NULL terminated) in .env:
+
+. If the string is of the form "VAR=value", i.e. it contains '='
+  the variable is added to the child process's environment.
+
+. If the string does not contain '=', it names an environment
+  variable that will be removed from the child process's environment.
+
+If the .env member is NULL, `start_command` will point it at the
+.env_array `argv_array` (so you may use one or the other, but not both).
+The memory in .env_array will be cleaned up automatically during
+`finish_command` (or during `start_command` when it is unsuccessful).
+
+To specify a new initial working directory for the sub-process,
+specify it in the .dir member.
+
+If the program cannot be found, the functions return -1 and set
+errno to ENOENT. Normally, an error message is printed, but if
+.silent_exec_failure is set to 1, no message is printed for this
+special error condition.
+
+
+* `struct async`
+
+This describes a function to run asynchronously, whose purpose is
+to produce output that the caller reads.
+
+The caller:
+
+1. allocates and clears (memset(&asy, 0, sizeof(asy));) a
+   struct async variable;
+2. initializes .proc and .data;
+3. calls start_async();
+4. processes communicates with proc through .in and .out;
+5. closes .in and .out;
+6. calls finish_async().
+
+The members .in, .out are used to provide a set of fd's for
+communication between the caller and the callee as follows:
+
+. Specify 0 to have no file descriptor passed.  The callee will
+  receive -1 in the corresponding argument.
+
+. Specify < 0 to have a pipe allocated; start_async() replaces
+  with the pipe FD in the following way:
+
+	.in: Returns the writable pipe end into which the caller
+	writes; the readable end of the pipe becomes the function's
+	in argument.
+
+	.out: Returns the readable pipe end from which the caller
+	reads; the writable end of the pipe becomes the function's
+	out argument.
+
+  The caller of start_async() must close the returned FDs after it
+  has completed reading from/writing from them.
+
+. Specify a file descriptor > 0 to be used by the function:
+
+	.in: The FD must be readable; it becomes the function's in.
+	.out: The FD must be writable; it becomes the function's out.
+
+  The specified FD is closed by start_async(), even if it fails to
+  run the function.
+
+The function pointer in .proc has the following signature:
+
+	int proc(int in, int out, void *data);
+
+. in, out specifies a set of file descriptors to which the function
+  must read/write the data that it needs/produces.  The function
+  *must* close these descriptors before it returns.  A descriptor
+  may be -1 if the caller did not configure a descriptor for that
+  direction.
+
+. data is the value that the caller has specified in the .data member
+  of struct async.
+
+. The return value of the function is 0 on success and non-zero
+  on failure. If the function indicates failure, finish_async() will
+  report failure as well.
+
+
+There are serious restrictions on what the asynchronous function can do
+because this facility is implemented by a thread in the same address
+space on most platforms (when pthreads is available), but by a pipe to
+a forked process otherwise:
+
+. It cannot change the program's state (global variables, environment,
+  etc.) in a way that the caller notices; in other words, .in and .out
+  are the only communication channels to the caller.
+
+. It must not change the program's state that the caller of the
+  facility also uses.

+Pathspec
+--------
+
+See glossary-context.txt for the syntax of pathspec. In memory, a
+pathspec set is represented by "struct pathspec" and is prepared by
+parse_pathspec(). This function takes several arguments:
+
+- magic_mask specifies what features that are NOT supported by the
+  following code. If a user attempts to use such a feature,
+  parse_pathspec() can reject it early.
+
+- flags specifies other things that the caller wants parse_pathspec to
+  perform.
+
+- prefix and args come from cmd_* functions
+
+get_pathspec() is obsolete and should never be used in new code.
+
+parse_pathspec() helps catch unsupported features and reject them
+politely. At a lower level, different pathspec-related functions may
+not support the same set of features. Such pathspec-sensitive
+functions are guarded with GUARD_PATHSPEC(), which will die in an
+unfriendly way when an unsupported feature is requested.
+
+The command designers are supposed to make sure that GUARD_PATHSPEC()
+never dies. They have to make sure all unsupported features are caught
+by parse_pathspec(), not by GUARD_PATHSPEC. grepping GUARD_PATHSPEC()
+should give the designers all pathspec-sensitive codepaths and what
+features they support.
+
+A similar process is applied when a new pathspec magic is added. The
+designer lifts the GUARD_PATHSPEC restriction in the functions that
+support the new magic. At the same time (s)he has to make sure this
+new feature will be caught at parse_pathspec() in commands that cannot
+handle the new magic in some cases. grepping parse_pathspec() should
+help.

+sha1-array API
+==============
+
+The sha1-array API provides storage and manipulation of sets of SHA-1
+identifiers. The emphasis is on storage and processing efficiency,
+making them suitable for large lists. Note that the ordering of items is
+not preserved over some operations.
+
+Data Structures
+---------------
+
+`struct sha1_array`::
+
+	A single array of SHA-1 hashes. This should be initialized by
+	assignment from `SHA1_ARRAY_INIT`.  The `sha1` member contains
+	the actual data. The `nr` member contains the number of items in
+	the set.  The `alloc` and `sorted` members are used internally,
+	and should not be needed by API callers.
+
+Functions
+---------
+
+`sha1_array_append`::
+	Add an item to the set. The sha1 will be placed at the end of
+	the array (but note that some operations below may lose this
+	ordering).
+
+`sha1_array_lookup`::
+	Perform a binary search of the array for a specific sha1.
+	If found, returns the offset (in number of elements) of the
+	sha1. If not found, returns a negative integer. If the array is
+	not sorted, this function has the side effect of sorting it.
+
+`sha1_array_clear`::
+	Free all memory associated with the array and return it to the
+	initial, empty state.
+
+`sha1_array_for_each_unique`::
+	Efficiently iterate over each unique element of the list,
+	executing the callback function for each one. If the array is
+	not sorted, this function has the side effect of sorting it.
+
+Examples
+--------
+
+-----------------------------------------
+void print_callback(const unsigned char sha1[20],
+		    void *data)
+{
+	printf("%s\n", sha1_to_hex(sha1));
+}
+
+void some_func(void)
+{
+	struct sha1_array hashes = SHA1_ARRAY_INIT;
+	unsigned char sha1[20];
+
+	/* Read objects into our set */
+	while (read_object_from_stdin(sha1))
+		sha1_array_append(&hashes, sha1);
+
+	/* Check if some objects are in our set */
+	while (read_object_from_stdin(sha1)) {
+		if (sha1_array_lookup(&hashes, sha1) >= 0)
+			printf("it's in there!\n");
+
+	/*
+	 * Print the unique set of objects. We could also have
+	 * avoided adding duplicate objects in the first place,
+	 * but we would end up re-sorting the array repeatedly.
+	 * Instead, this will sort once and then skip duplicates
+	 * in linear time.
+	 */
+	sha1_array_for_each_unique(&hashes, print_callback, NULL);

+sigchain API
+============
+
+Code often wants to set a signal handler to clean up temporary files or
+other work-in-progress when we die unexpectedly. For multiple pieces of
+code to do this without conflicting, each piece of code must remember
+the old value of the handler and restore it either when:
+
+  1. The work-in-progress is finished, and the handler is no longer
+     necessary. The handler should revert to the original behavior
+     (either another handler, SIG_DFL, or SIG_IGN).
+
+  2. The signal is received. We should then do our cleanup, then chain
+     to the next handler (or die if it is SIG_DFL).
+
+Sigchain is a tiny library for keeping a stack of handlers. Your handler
+and installation code should look something like:
+
+------------------------------------------
+  void clean_foo_on_signal(int sig)
+  {
+	  clean_foo();
+	  sigchain_pop(sig);
+	  raise(sig);
+  }
+
+  void other_func()
+  {
+	  sigchain_push_common(clean_foo_on_signal);
+	  mess_up_foo();
+	  clean_foo();
+  }
+------------------------------------------
+
+Handlers are given the typedef of sigchain_fun. This is the same type
+that is given to signal() or sigaction(). It is perfectly reasonable to
+push SIG_DFL or SIG_IGN onto the stack.
+
+You can sigchain_push and sigchain_pop individual signals. For
+convenience, sigchain_push_common will push the handler onto the stack
+for many common signals.

+string-list API
+===============
+
+The string_list API offers a data structure and functions to handle
+sorted and unsorted string lists.  A "sorted" list is one whose
+entries are sorted by string value in `strcmp()` order.
+
+The 'string_list' struct used to be called 'path_list', but was renamed
+because it is not specific to paths.
+
+The caller:
+
+. Allocates and clears a `struct string_list` variable.
+
+. Initializes the members. You might want to set the flag `strdup_strings`
+  if the strings should be strdup()ed. For example, this is necessary
+  when you add something like git_path("..."), since that function returns
+  a static buffer that will change with the next call to git_path().
++
+If you need something advanced, you can manually malloc() the `items`
+member (you need this if you add things later) and you should set the
+`nr` and `alloc` members in that case, too.
+
+. Adds new items to the list, using `string_list_append`,
+  `string_list_append_nodup`, `string_list_insert`,
+  `string_list_split`, and/or `string_list_split_in_place`.
+
+. Can check if a string is in the list using `string_list_has_string` or
+  `unsorted_string_list_has_string` and get it from the list using
+  `string_list_lookup` for sorted lists.
+
+. Can sort an unsorted list using `string_list_sort`.
+
+. Can remove duplicate items from a sorted list using
+  `string_list_remove_duplicates`.
+
+. Can remove individual items of an unsorted list using
+  `unsorted_string_list_delete_item`.
+
+. Can remove items not matching a criterion from a sorted or unsorted
+  list using `filter_string_list`, or remove empty strings using
+  `string_list_remove_empty_items`.
+
+. Finally it should free the list using `string_list_clear`.
+
+Example:
+
+----
+struct string_list list = STRING_LIST_INIT_NODUP;
+int i;
+
+string_list_append(&list, "foo");
+string_list_append(&list, "bar");
+for (i = 0; i < list.nr; i++)
+	printf("%s\n", list.items[i].string)
+----
+
+NOTE: It is more efficient to build an unsorted list and sort it
+afterwards, instead of building a sorted list (`O(n log n)` instead of
+`O(n^2)`).
++
+However, if you use the list to check if a certain string was added
+already, you should not do that (using unsorted_string_list_has_string()),
+because the complexity would be quadratic again (but with a worse factor).
+
+Functions
+---------
+
+* General ones (works with sorted and unsorted lists as well)
+
+`string_list_init`::
+
+	Initialize the members of the string_list, set `strdup_strings`
+	member according to the value of the second parameter.
+
+`filter_string_list`::
+
+	Apply a function to each item in a list, retaining only the
+	items for which the function returns true.  If free_util is
+	true, call free() on the util members of any items that have
+	to be deleted.  Preserve the order of the items that are
+	retained.
+
+`string_list_remove_empty_items`::
+
+	Remove any empty strings from the list.  If free_util is true,
+	call free() on the util members of any items that have to be
+	deleted.  Preserve the order of the items that are retained.
+
+`print_string_list`::
+
+	Dump a string_list to stdout, useful mainly for debugging purposes. It
+	can take an optional header argument and it writes out the
+	string-pointer pairs of the string_list, each one in its own line.
+
+`string_list_clear`::
+
+	Free a string_list. The `string` pointer of the items will be freed in
+	case the `strdup_strings` member of the string_list is set. The second
+	parameter controls if the `util` pointer of the items should be freed
+	or not.
+
+* Functions for sorted lists only
+
+`string_list_has_string`::
+
+	Determine if the string_list has a given string or not.
+
+`string_list_insert`::
+
+	Insert a new element to the string_list. The returned pointer can be
+	handy if you want to write something to the `util` pointer of the
+	string_list_item containing the just added string. If the given
+	string already exists the insertion will be skipped and the
+	pointer to the existing item returned.
++
+Since this function uses xrealloc() (which die()s if it fails) if the
+list needs to grow, it is safe not to check the pointer. I.e. you may
+write `string_list_insert(...)->util = ...;`.
+
+`string_list_lookup`::
+
+	Look up a given string in the string_list, returning the containing
+	string_list_item. If the string is not found, NULL is returned.
+
+`string_list_remove_duplicates`::
+
+	Remove all but the first of consecutive entries that have the
+	same string value.  If free_util is true, call free() on the
+	util members of any items that have to be deleted.
+
+* Functions for unsorted lists only
+
+`string_list_append`::
+
+	Append a new string to the end of the string_list.  If
+	`strdup_string` is set, then the string argument is copied;
+	otherwise the new `string_list_entry` refers to the input
+	string.
+
+`string_list_append_nodup`::
+
+	Append a new string to the end of the string_list.  The new
+	`string_list_entry` always refers to the input string, even if
+	`strdup_string` is set.  This function can be used to hand
+	ownership of a malloc()ed string to a `string_list` that has
+	`strdup_string` set.
+
+`string_list_sort`::
+
+	Sort the list's entries by string value in `strcmp()` order.
+
+`unsorted_string_list_has_string`::
+
+	It's like `string_list_has_string()` but for unsorted lists.
+
+`unsorted_string_list_lookup`::
+
+	It's like `string_list_lookup()` but for unsorted lists.
++
+The above two functions need to look through all items, as opposed to their
+counterpart for sorted lists, which performs a binary search.
+
+`unsorted_string_list_delete_item`::
+
+	Remove an item from a string_list. The `string` pointer of the items
+	will be freed in case the `strdup_strings` member of the string_list
+	is set. The third parameter controls if the `util` pointer of the
+	items should be freed or not.
+
+`string_list_split`::
+`string_list_split_in_place`::
+
+	Split a string into substrings on a delimiter character and
+	append the substrings to a `string_list`.  If `maxsplit` is
+	non-negative, then split at most `maxsplit` times.  Return the
+	number of substrings appended to the list.
++
+`string_list_split` requires a `string_list` that has `strdup_strings`
+set to true; it leaves the input string untouched and makes copies of
+the substrings in newly-allocated memory.
+`string_list_split_in_place` requires a `string_list` that has
+`strdup_strings` set to false; it splits the input string in place,
+overwriting the delimiter characters with NULs and creating new
+string_list_items that point into the original string (the original
+string must therefore not be modified or freed while the `string_list`
+is in use).
+
+
+Data structures
+---------------
+
+* `struct string_list_item`
+
+Represents an item of the list. The `string` member is a pointer to the
+string, and you may use the `util` member for any purpose, if you want.
+
+* `struct string_list`
+
+Represents the list itself.
+
+. The array of items are available via the `items` member.
+. The `nr` member contains the number of items stored in the list.
+. The `alloc` member is used to avoid reallocating at every insertion.
+  You should not tamper with it.
+. Setting the `strdup_strings` member to 1 will strdup() the strings
+  before adding them, see above.
+. The `compare_strings_fn` member is used to specify a custom compare
+  function, otherwise `strcmp()` is used as the default function.

+submodule config cache API
+==========================
+
+The submodule config cache API allows to read submodule
+configurations/information from specified revisions. Internally
+information is lazily read into a cache that is used to avoid
+unnecessary parsing of the same .gitmodule files. Lookups can be done by
+submodule path or name.
+
+Usage
+-----
+
+To initialize the cache with configurations from the worktree the caller
+typically first calls `gitmodules_config()` to read values from the
+worktree .gitmodules and then to overlay the local git config values
+`parse_submodule_config_option()` from the config parsing
+infrastructure.
+
+The caller can look up information about submodules by using the
+`submodule_from_path()` or `submodule_from_name()` functions. They return
+a `struct submodule` which contains the values. The API automatically
+initializes and allocates the needed infrastructure on-demand. If the
+caller does only want to lookup values from revisions the initialization
+can be skipped.
+
+If the internal cache might grow too big or when the caller is done with
+the API, all internally cached values can be freed with submodule_free().
+
+Data Structures
+---------------
+
+`struct submodule`::
+
+	This structure is used to return the information about one
+	submodule for a certain revision. It is returned by the lookup
+	functions.
+
+Functions
+---------
+
+`void submodule_free()`::
+
+	Use these to free the internally cached values.
+
+`int parse_submodule_config_option(const char *var, const char *value)`::
+
+	Can be passed to the config parsing infrastructure to parse
+	local (worktree) submodule configurations.
+
+`const struct submodule *submodule_from_path(const unsigned char *commit_sha1, const char *path)`::
+
+	Lookup values for one submodule by its commit_sha1 and path.
+
+`const struct submodule *submodule_from_name(const unsigned char *commit_sha1, const char *name)`::
+
+	The same as above but lookup by name.
+
+If given the null_sha1 as commit_sha1 the local configuration of a
+submodule will be returned (e.g. consolidated values from local git
+configuration and the .gitmodules file in the worktree).
+
+For an example usage see test-submodule-config.c.

+trace API
+=========
+
+The trace API can be used to print debug messages to stderr or a file. Trace
+code is inactive unless explicitly enabled by setting `GIT_TRACE*` environment
+variables.
+
+The trace implementation automatically adds `timestamp file:line ... \n` to
+all trace messages. E.g.:
+
+------------
+23:59:59.123456 git.c:312               trace: built-in: git 'foo'
+00:00:00.000001 builtin/foo.c:99        foo: some message
+------------
+
+Data Structures
+---------------
+
+`struct trace_key`::
+
+	Defines a trace key (or category). The default (for API functions that
+	don't take a key) is `GIT_TRACE`.
++
+E.g. to define a trace key controlled by environment variable `GIT_TRACE_FOO`:
++
+------------
+static struct trace_key trace_foo = TRACE_KEY_INIT(FOO);
+
+static void trace_print_foo(const char *message)
+{
+	trace_print_key(&trace_foo, message);
+}
+------------
++
+Note: don't use `const` as the trace implementation stores internal state in
+the `trace_key` structure.
+
+Functions
+---------
+
+`int trace_want(struct trace_key *key)`::
+
+	Checks whether the trace key is enabled. Used to prevent expensive
+	string formatting before calling one of the printing APIs.
+
+`void trace_disable(struct trace_key *key)`::
+
+	Disables tracing for the specified key, even if the environment
+	variable was set.
+
+`void trace_printf(const char *format, ...)`::
+`void trace_printf_key(struct trace_key *key, const char *format, ...)`::
+
+	Prints a formatted message, similar to printf.
+
+`void trace_argv_printf(const char **argv, const char *format, ...)``::
+
+	Prints a formatted message, followed by a quoted list of arguments.
+
+`void trace_strbuf(struct trace_key *key, const struct strbuf *data)`::
+
+	Prints the strbuf, without additional formatting (i.e. doesn't
+	choke on `%` or even `\0`).
+
+`uint64_t getnanotime(void)`::
+
+	Returns nanoseconds since the epoch (01/01/1970), typically used
+	for performance measurements.
++
+Currently there are high precision timer implementations for Linux (using
+`clock_gettime(CLOCK_MONOTONIC)`) and Windows (`QueryPerformanceCounter`).
+Other platforms use `gettimeofday` as time source.
+
+`void trace_performance(uint64_t nanos, const char *format, ...)`::
+`void trace_performance_since(uint64_t start, const char *format, ...)`::
+
+	Prints the elapsed time (in nanoseconds), or elapsed time since
+	`start`, followed by a formatted message. Enabled via environment
+	variable `GIT_TRACE_PERFORMANCE`. Used for manual profiling, e.g.:
++
+------------
+uint64_t start = getnanotime();
+/* code section to measure */
+trace_performance_since(start, "foobar");
+------------
++
+------------
+uint64_t t = 0;
+for (;;) {
+	/* ignore */
+	t -= getnanotime();
+	/* code section to measure */
+	t += getnanotime();
+	/* ignore */
+}

+tree walking API
+================
+
+The tree walking API is used to traverse and inspect trees.
+
+Data Structures
+---------------
+
+`struct name_entry`::
+
+	An entry in a tree. Each entry has a sha1 identifier, pathname, and
+	mode.
+
+`struct tree_desc`::
+
+	A semi-opaque data structure used to maintain the current state of the
+	walk.
++
+* `buffer` is a pointer into the memory representation of the tree. It always
+points at the current entry being visited.
+
+* `size` counts the number of bytes left in the `buffer`.
+
+* `entry` points to the current entry being visited.
+
+`struct traverse_info`::
+
+	A structure used to maintain the state of a traversal.
++
+* `prev` points to the traverse_info which was used to descend into the
+current tree. If this is the top-level tree `prev` will point to
+a dummy traverse_info.
+
+* `name` is the entry for the current tree (if the tree is a subtree).
+
+* `pathlen` is the length of the full path for the current tree.
+
+* `conflicts` can be used by callbacks to maintain directory-file conflicts.
+
+* `fn` is a callback called for each entry in the tree. See Traversing for more
+information.
+
+* `data` can be anything the `fn` callback would want to use.
+
+* `show_all_errors` tells whether to stop at the first error or not.
+
+Initializing
+------------
+
+`init_tree_desc`::
+
+	Initialize a `tree_desc` and decode its first entry. The buffer and
+	size parameters are assumed to be the same as the buffer and size
+	members of `struct tree`.
+
+`fill_tree_descriptor`::
+
+	Initialize a `tree_desc` and decode its first entry given the sha1 of
+	a tree. Returns the `buffer` member if the sha1 is a valid tree
+	identifier and NULL otherwise.
+
+`setup_traverse_info`::
+
+	Initialize a `traverse_info` given the pathname of the tree to start
+	traversing from. The `base` argument is assumed to be the `path`
+	member of the `name_entry` being recursed into unless the tree is a
+	top-level tree in which case the empty string ("") is used.
+
+Walking
+-------
+
+`tree_entry`::
+
+	Visit the next entry in a tree. Returns 1 when there are more entries
+	left to visit and 0 when all entries have been visited. This is
+	commonly used in the test of a while loop.
+
+`tree_entry_len`::
+
+	Calculate the length of a tree entry's pathname. This utilizes the
+	memory structure of a tree entry to avoid the overhead of using a
+	generic strlen().
+
+`update_tree_entry`::
+
+	Walk to the next entry in a tree. This is commonly used in conjunction
+	with `tree_entry_extract` to inspect the current entry.
+
+`tree_entry_extract`::
+
+	Decode the entry currently being visited (the one pointed to by
+	`tree_desc's` `entry` member) and return the sha1 of the entry. The
+	`pathp` and `modep` arguments are set to the entry's pathname and mode
+	respectively.
+
+`get_tree_entry`::
+
+	Find an entry in a tree given a pathname and the sha1 of a tree to
+	search. Returns 0 if the entry is found and -1 otherwise. The third
+	and fourth parameters are set to the entry's sha1 and mode
+	respectively.
+
+Traversing
+----------
+
+`traverse_trees`::
+
+	Traverse `n` number of trees in parallel. The `fn` callback member of
+	`traverse_info` is called once for each tree entry.
+
+`traverse_callback_t`::
+	The arguments passed to the traverse callback are as follows:
++
+* `n` counts the number of trees being traversed.
+
+* `mask` has its nth bit set if something exists in the nth entry.
+
+* `dirmask` has its nth bit set if the nth tree's entry is a directory.
+
+* `entry` is an array of size `n` where the nth entry is from the nth tree.
+
+* `info` maintains the state of the traversal.
+
++
+Returning a negative value will terminate the traversal. Otherwise the
+return value is treated as an update mask. If the nth bit is set the nth tree
+will be updated and if the bit is not set the nth tree entry will be the
+same in the next callback invocation.
+
+`make_traverse_path`::
+
+	Generate the full pathname of a tree entry based from the root of the
+	traversal. For example, if the traversal has recursed into another
+	tree named "bar" the pathname of an entry "baz" in the "bar"
+	tree would be "bar/baz".
+
+`traverse_path_len`::
+
+	Calculate the length of a pathname returned by `make_traverse_path`.
+	This utilizes the memory structure of a tree entry to avoid the
+	overhead of using a generic strlen().

+GIT bitmap v1 format
+====================
+
+	- A header appears at the beginning:
+
+		4-byte signature: {'B', 'I', 'T', 'M'}
+
+		2-byte version number (network byte order)
+			The current implementation only supports version 1
+			of the bitmap index (the same one as JGit).
+
+		2-byte flags (network byte order)
+
+			The following flags are supported:
+
+			- BITMAP_OPT_FULL_DAG (0x1) REQUIRED
+			This flag must always be present. It implies that the bitmap
+			index has been generated for a packfile with full closure
+			(i.e. where every single object in the packfile can find
+			 its parent links inside the same packfile). This is a
+			requirement for the bitmap index format, also present in JGit,
+			that greatly reduces the complexity of the implementation.
+
+			- BITMAP_OPT_HASH_CACHE (0x4)
+			If present, the end of the bitmap file contains
+			`N` 32-bit name-hash values, one per object in the
+			pack. The format and meaning of the name-hash is
+			described below.
+
+		4-byte entry count (network byte order)
+
+			The total count of entries (bitmapped commits) in this bitmap index.
+
+		20-byte checksum
+
+			The SHA1 checksum of the pack this bitmap index belongs to.
+
+	- 4 EWAH bitmaps that act as type indexes
+
+		Type indexes are serialized after the hash cache in the shape
+		of four EWAH bitmaps stored consecutively (see Appendix A for
+		the serialization format of an EWAH bitmap).
+
+		There is a bitmap for each Git object type, stored in the following
+		order:
+
+			- Commits
+			- Trees
+			- Blobs
+			- Tags
+
+		In each bitmap, the `n`th bit is set to true if the `n`th object
+		in the packfile is of that type.
+
+		The obvious consequence is that the OR of all 4 bitmaps will result
+		in a full set (all bits set), and the AND of all 4 bitmaps will
+		result in an empty bitmap (no bits set).
+
+	- N entries with compressed bitmaps, one for each indexed commit
+
+		Where `N` is the total amount of entries in this bitmap index.
+		Each entry contains the following:
+
+		- 4-byte object position (network byte order)
+			The position **in the index for the packfile** where the
+			bitmap for this commit is found.
+
+		- 1-byte XOR-offset
+			The xor offset used to compress this bitmap. For an entry
+			in position `x`, a XOR offset of `y` means that the actual
+			bitmap representing this commit is composed by XORing the
+			bitmap for this entry with the bitmap in entry `x-y` (i.e.
+			the bitmap `y` entries before this one).
+
+			Note that this compression can be recursive. In order to
+			XOR this entry with a previous one, the previous entry needs
+			to be decompressed first, and so on.
+
+			The hard-limit for this offset is 160 (an entry can only be
+			xor'ed against one of the 160 entries preceding it). This
+			number is always positive, and hence entries are always xor'ed
+			with **previous** bitmaps, not bitmaps that will come afterwards
+			in the index.
+
+		- 1-byte flags for this bitmap
+			At the moment the only available flag is `0x1`, which hints
+			that this bitmap can be re-used when rebuilding bitmap indexes
+			for the repository.
+
+		- The compressed bitmap itself, see Appendix A.
+
+== Appendix A: Serialization format for an EWAH bitmap
+
+Ewah bitmaps are serialized in the same protocol as the JAVAEWAH
+library, making them backwards compatible with the JGit
+implementation:
+
+	- 4-byte number of bits of the resulting UNCOMPRESSED bitmap
+
+	- 4-byte number of words of the COMPRESSED bitmap, when stored
+
+	- N x 8-byte words, as specified by the previous field
+
+		This is the actual content of the compressed bitmap.
+
+	- 4-byte position of the current RLW for the compressed
+		bitmap
+
+All words are stored in network byte order for their corresponding
+sizes.
+
+The compressed bitmap is stored in a form of run-length encoding, as
+follows.  It consists of a concatenation of an arbitrary number of
+chunks.  Each chunk consists of one or more 64-bit words
+
+     H  L_1  L_2  L_3 .... L_M
+
+H is called RLW (run length word).  It consists of (from lower to higher
+order bits):
+
+     - 1 bit: the repeated bit B
+
+     - 32 bits: repetition count K (unsigned)
+
+     - 31 bits: literal word count M (unsigned)
+
+The bitstream represented by the above chunk is then:
+
+     - K repetitions of B
+
+     - The bits stored in `L_1` through `L_M`.  Within a word, bits at
+       lower order come earlier in the stream than those at higher
+       order.
+
+The next word after `L_M` (if any) must again be a RLW, for the next
+chunk.  For efficient appending to the bitstream, the EWAH stores a
+pointer to the last RLW in the stream.
+
+
+== Appendix B: Optional Bitmap Sections
+
+These sections may or may not be present in the `.bitmap` file; their
+presence is indicated by the header flags section described above.
+
+Name-hash cache
+---------------
+
+If the BITMAP_OPT_HASH_CACHE flag is set, the end of the bitmap contains
+a cache of 32-bit values, one per object in the pack. The value at
+position `i` is the hash of the pathname at which the `i`th object
+(counting in index order) in the pack can be found.  This can be fed
+into the delta heuristics to compare objects with similar pathnames.
+
+The hash algorithm used is:
+
+    hash = 0;
+    while ((c = *name++))
+	    if (!isspace(c))
+		    hash = (hash >> 2) + (c << 24);
+
+Note that this hashing scheme is tied to the BITMAP_OPT_HASH_CACHE flag.
+If implementations want to choose a different hashing scheme, they are
+free to do so, but MUST allocate a new header flag (because comparing
+hashes made under two different schemes would be pointless).

+HTTP transfer protocols
+=======================
+
+Git supports two HTTP based transfer protocols.  A "dumb" protocol
+which requires only a standard HTTP server on the server end of the
+connection, and a "smart" protocol which requires a Git aware CGI
+(or server module).  This document describes both protocols.
+
+As a design feature smart clients can automatically upgrade "dumb"
+protocol URLs to smart URLs.  This permits all users to have the
+same published URL, and the peers automatically select the most
+efficient transport available to them.
+
+
+URL Format
+----------
+
+URLs for Git repositories accessed by HTTP use the standard HTTP
+URL syntax documented by RFC 1738, so they are of the form:
+
+  http://<host>:<port>/<path>?<searchpart>
+
+Within this documentation the placeholder `$GIT_URL` will stand for
+the http:// repository URL entered by the end-user.
+
+Servers SHOULD handle all requests to locations matching `$GIT_URL`, as
+both the "smart" and "dumb" HTTP protocols used by Git operate
+by appending additional path components onto the end of the user
+supplied `$GIT_URL` string.
+
+An example of a dumb client requesting for a loose object:
+
+  $GIT_URL:     http://example.com:8080/git/repo.git
+  URL request:  http://example.com:8080/git/repo.git/objects/d0/49f6c27a2244e12041955e262a404c7faba355
+
+An example of a smart request to a catch-all gateway:
+
+  $GIT_URL:     http://example.com/daemon.cgi?svc=git&q=
+  URL request:  http://example.com/daemon.cgi?svc=git&q=/info/refs&service=git-receive-pack
+
+An example of a request to a submodule:
+
+  $GIT_URL:     http://example.com/git/repo.git/path/submodule.git
+  URL request:  http://example.com/git/repo.git/path/submodule.git/info/refs
+
+Clients MUST strip a trailing `/`, if present, from the user supplied
+`$GIT_URL` string to prevent empty path tokens (`//`) from appearing
+in any URL sent to a server.  Compatible clients MUST expand
+`$GIT_URL/info/refs` as `foo/info/refs` and not `foo//info/refs`.
+
+
+Authentication
+--------------
+
+Standard HTTP authentication is used if authentication is required
+to access a repository, and MAY be configured and enforced by the
+HTTP server software.
+
+Because Git repositories are accessed by standard path components
+server administrators MAY use directory based permissions within
+their HTTP server to control repository access.
+
+Clients SHOULD support Basic authentication as described by RFC 2617.
+Servers SHOULD support Basic authentication by relying upon the
+HTTP server placed in front of the Git server software.
+
+Servers SHOULD NOT require HTTP cookies for the purposes of
+authentication or access control.
+
+Clients and servers MAY support other common forms of HTTP based
+authentication, such as Digest authentication.
+
+
+SSL
+---
+
+Clients and servers SHOULD support SSL, particularly to protect
+passwords when relying on Basic HTTP authentication.
+
+
+Session State
+-------------
+
+The Git over HTTP protocol (much like HTTP itself) is stateless
+from the perspective of the HTTP server side.  All state MUST be
+retained and managed by the client process.  This permits simple
+round-robin load-balancing on the server side, without needing to
+worry about state management.
+
+Clients MUST NOT require state management on the server side in
+order to function correctly.
+
+Servers MUST NOT require HTTP cookies in order to function correctly.
+Clients MAY store and forward HTTP cookies during request processing
+as described by RFC 2616 (HTTP/1.1).  Servers SHOULD ignore any
+cookies sent by a client.
+
+
+General Request Processing
+--------------------------
+
+Except where noted, all standard HTTP behavior SHOULD be assumed
+by both client and server.  This includes (but is not necessarily
+limited to):
+
+If there is no repository at `$GIT_URL`, or the resource pointed to by a
+location matching `$GIT_URL` does not exist, the server MUST NOT respond
+with `200 OK` response.  A server SHOULD respond with
+`404 Not Found`, `410 Gone`, or any other suitable HTTP status code
+which does not imply the resource exists as requested.
+
+If there is a repository at `$GIT_URL`, but access is not currently
+permitted, the server MUST respond with the `403 Forbidden` HTTP
+status code.
+
+Servers SHOULD support both HTTP 1.0 and HTTP 1.1.
+Servers SHOULD support chunked encoding for both request and response
+bodies.
+
+Clients SHOULD support both HTTP 1.0 and HTTP 1.1.
+Clients SHOULD support chunked encoding for both request and response
+bodies.
+
+Servers MAY return ETag and/or Last-Modified headers.
+
+Clients MAY revalidate cached entities by including If-Modified-Since
+and/or If-None-Match request headers.
+
+Servers MAY return `304 Not Modified` if the relevant headers appear
+in the request and the entity has not changed.  Clients MUST treat
+`304 Not Modified` identical to `200 OK` by reusing the cached entity.
+
+Clients MAY reuse a cached entity without revalidation if the
+Cache-Control and/or Expires header permits caching.  Clients and
+servers MUST follow RFC 2616 for cache controls.
+
+
+Discovering References
+----------------------
+
+All HTTP clients MUST begin either a fetch or a push exchange by
+discovering the references available on the remote repository.
+
+Dumb Clients
+~~~~~~~~~~~~
+
+HTTP clients that only support the "dumb" protocol MUST discover
+references by making a request for the special info/refs file of
+the repository.
+
+Dumb HTTP clients MUST make a `GET` request to `$GIT_URL/info/refs`,
+without any search/query parameters.
+
+   C: GET $GIT_URL/info/refs HTTP/1.0
+
+   S: 200 OK
+   S:
+   S: 95dcfa3633004da0049d3d0fa03f80589cbcaf31	refs/heads/maint
+   S: d049f6c27a2244e12041955e262a404c7faba355	refs/heads/master

+   S: a3c2e2402b99163d1d59756e5f207ae21cccba4c	refs/tags/v1.0^{}
+
+The Content-Type of the returned info/refs entity SHOULD be
+`text/plain; charset=utf-8`, but MAY be any content type.
+Clients MUST NOT attempt to validate the returned Content-Type.
+Dumb servers MUST NOT return a return type starting with
+`application/x-git-`.
+
+Cache-Control headers MAY be returned to disable caching of the
+returned entity.
+
+When examining the response clients SHOULD only examine the HTTP
+status code.  Valid responses are `200 OK`, or `304 Not Modified`.
+
+The returned content is a UNIX formatted text file describing
+each ref and its known value.  The file SHOULD be sorted by name
+according to the C locale ordering.  The file SHOULD NOT include
+the default ref named `HEAD`.
+
+  info_refs   =  *( ref_record )
+  ref_record  =  any_ref / peeled_ref
+
+  any_ref     =  obj-id HTAB refname LF
+  peeled_ref  =  obj-id HTAB refname LF
+		 obj-id HTAB refname "^{}" LF
+
+Smart Clients
+~~~~~~~~~~~~~
+
+HTTP clients that support the "smart" protocol (or both the
+"smart" and "dumb" protocols) MUST discover references by making
+a parameterized request for the info/refs file of the repository.
+
+The request MUST contain exactly one query parameter,
+`service=$servicename`, where `$servicename` MUST be the service
+name the client wishes to contact to complete the operation.
+The request MUST NOT contain additional query parameters.
+
+   C: GET $GIT_URL/info/refs?service=git-upload-pack HTTP/1.0

+
+Dumb Server Response
+^^^^^^^^^^^^^^^^^^^^
+Dumb servers MUST respond with the dumb server reply format.
+
+See the prior section under dumb clients for a more detailed
+description of the dumb server response.
+
+Smart Server Response
+^^^^^^^^^^^^^^^^^^^^^
+If the server does not recognize the requested service name, or the
+requested service name has been disabled by the server administrator,
+the server MUST respond with the `403 Forbidden` HTTP status code.
+
+Otherwise, smart servers MUST respond with the smart server reply
+format for the requested service name.
+
+Cache-Control headers SHOULD be used to disable caching of the
+returned entity.
+
+The Content-Type MUST be `application/x-$servicename-advertisement`.
+Clients SHOULD fall back to the dumb protocol if another content
+type is returned.  When falling back to the dumb protocol clients
+SHOULD NOT make an additional request to `$GIT_URL/info/refs`, but
+instead SHOULD use the response already in hand.  Clients MUST NOT
+continue if they do not support the dumb protocol.
+
+Clients MUST validate the status code is either `200 OK` or
+`304 Not Modified`.
+
+Clients MUST validate the first five bytes of the response entity
+matches the regex `^[0-9a-f]{4}#`.  If this test fails, clients
+MUST NOT continue.
+
+Clients MUST parse the entire response as a sequence of pkt-line
+records.
+
+Clients MUST verify the first pkt-line is `# service=$servicename`.
+Servers MUST set $servicename to be the request parameter value.
+Servers SHOULD include an LF at the end of this line.
+Clients MUST ignore an LF at the end of the line.
+
+Servers MUST terminate the response with the magic `0000` end
+pkt-line marker.
+
+The returned response is a pkt-line stream describing each ref and
+its known value.  The stream SHOULD be sorted by name according to
+the C locale ordering.  The stream SHOULD include the default ref
+named `HEAD` as the first ref.  The stream MUST include capability
+declarations behind a NUL on the first ref.
+
+  smart_reply     =  PKT-LINE("# service=$servicename" LF)
+		     ref_list
+		     "0000"
+  ref_list        =  empty_list / non_empty_list
+
+  empty_list      =  PKT-LINE(zero-id SP "capabilities^{}" NUL cap-list LF)
+
+  non_empty_list  =  PKT-LINE(obj-id SP name NUL cap_list LF)
+		     *ref_record
+
+  cap-list        =  capability *(SP capability)
+  capability      =  1*(LC_ALPHA / DIGIT / "-" / "_")
+  LC_ALPHA        =  %x61-7A
+
+  ref_record      =  any_ref / peeled_ref
+  any_ref         =  PKT-LINE(obj-id SP name LF)
+  peeled_ref      =  PKT-LINE(obj-id SP name LF)
+		     PKT-LINE(obj-id SP name "^{}" LF
+
+
+Smart Service git-upload-pack
+------------------------------
+This service reads from the repository pointed to by `$GIT_URL`.
+
+Clients MUST first perform ref discovery with
+`$GIT_URL/info/refs?service=git-upload-pack`.
+
+   C: POST $GIT_URL/git-upload-pack HTTP/1.0
+   C: Content-Type: application/x-git-upload-pack-request
+   C:
+   C: 0032want 0a53e9ddeaddad63ad106860237bbf53411d11a7\n
+   C: 0032have 441b40d833fdfa93eb2908e52742248faf0ee993\n
+   C: 0000
+
+   S: 200 OK
+   S: Content-Type: application/x-git-upload-pack-result
+   S: Cache-Control: no-cache
+   S:
+   S: ....ACK %s, continue
+   S: ....NAK
+
+Clients MUST NOT reuse or revalidate a cached response.
+Servers MUST include sufficient Cache-Control headers
+to prevent caching of the response.
+
+Servers SHOULD support all capabilities defined here.
+
+Clients MUST send at least one "want" command in the request body.
+Clients MUST NOT reference an id in a "want" command which did not
+appear in the response obtained through ref discovery unless the
+server advertises capability `allow-tip-sha1-in-want` or
+`allow-reachable-sha1-in-want`.
+
+  compute_request   =  want_list
+		       have_list
+		       request_end
+  request_end       =  "0000" / "done"
+
+  want_list         =  PKT-LINE(want NUL cap_list LF)
+		       *(want_pkt)
+  want_pkt          =  PKT-LINE(want LF)
+  want              =  "want" SP id
+  cap_list          =  *(SP capability) SP
+
+  have_list         =  *PKT-LINE("have" SP id LF)
+
+TODO: Document this further.
+
+The Negotiation Algorithm
+~~~~~~~~~~~~~~~~~~~~~~~~~
+The computation to select the minimal pack proceeds as follows
+(C = client, S = server):
+
+'init step:'
+
+C: Use ref discovery to obtain the advertised refs.
+
+C: Place any object seen into set `advertised`.
+
+C: Build an empty set, `common`, to hold the objects that are later
+   determined to be on both ends.
+
+C: Build a set, `want`, of the objects from `advertised` the client
+   wants to fetch, based on what it saw during ref discovery.
+
+C: Start a queue, `c_pending`, ordered by commit time (popping newest
+   first).  Add all client refs.  When a commit is popped from
+   the queue its parents SHOULD be automatically inserted back.
+   Commits MUST only enter the queue once.
+
+'one compute step:'
+
+C: Send one `$GIT_URL/git-upload-pack` request:
+
+   C: 0032want <want #1>...............................
+   C: 0032want <want #2>...............................
+   ....
+   C: 0032have <common #1>.............................
+   C: 0032have <common #2>.............................
+   ....
+   C: 0032have <have #1>...............................
+   C: 0032have <have #2>...............................
+   ....
+   C: 0000
+
+The stream is organized into "commands", with each command
+appearing by itself in a pkt-line.  Within a command line,
+the text leading up to the first space is the command name,
+and the remainder of the line to the first LF is the value.
+Command lines are terminated with an LF as the last byte of
+the pkt-line value.
+
+Commands MUST appear in the following order, if they appear
+at all in the request stream:
+
+* "want"
+* "have"
+
+The stream is terminated by a pkt-line flush (`0000`).
+
+A single "want" or "have" command MUST have one hex formatted
+SHA-1 as its value.  Multiple SHA-1s MUST be sent by sending
+multiple commands.
+
+The `have` list is created by popping the first 32 commits
+from `c_pending`.  Less can be supplied if `c_pending` empties.
+
+If the client has sent 256 "have" commits and has not yet
+received one of those back from `s_common`, or the client has
+emptied `c_pending` it SHOULD include a "done" command to let
+the server know it won't proceed:
+
+   C: 0009done
+
+S: Parse the git-upload-pack request:
+
+Verify all objects in `want` are directly reachable from refs.
+
+The server MAY walk backwards through history or through
+the reflog to permit slightly stale requests.
+
+If no "want" objects are received, send an error:
+TODO: Define error if no "want" lines are requested.
+
+If any "want" object is not reachable, send an error:
+TODO: Define error if an invalid "want" is requested.
+
+Create an empty list, `s_common`.
+
+If "have" was sent:
+
+Loop through the objects in the order supplied by the client.
+
+For each object, if the server has the object reachable from
+a ref, add it to `s_common`.  If a commit is added to `s_common`,
+do not add any ancestors, even if they also appear in `have`.
+
+S: Send the git-upload-pack response:
+
+If the server has found a closed set of objects to pack or the
+request ends with "done", it replies with the pack.
+TODO: Document the pack based response
+
+   S: PACK...
+
+The returned stream is the side-band-64k protocol supported
+by the git-upload-pack service, and the pack is embedded into
+stream 1.  Progress messages from the server side MAY appear
+in stream 2.
+
+Here a "closed set of objects" is defined to have at least
+one path from every "want" to at least one "common" object.
+
+If the server needs more information, it replies with a
+status continue response:
+TODO: Document the non-pack response
+
+C: Parse the upload-pack response:
+   TODO: Document parsing response
+
+'Do another compute step.'
+
+
+Smart Service git-receive-pack
+------------------------------
+This service reads from the repository pointed to by `$GIT_URL`.
+
+Clients MUST first perform ref discovery with
+`$GIT_URL/info/refs?service=git-receive-pack`.

+Servers SHOULD support all capabilities defined here.
+
+Clients MUST send at least one command in the request body.

+Git index format
+================
+
+== The Git index file has the following format
+
+  All binary numbers are in network byte order. Version 2 is described
+  here unless stated otherwise.
+
+   - A 12-byte header consisting of
+
+     4-byte signature:
+       The signature is { 'D', 'I', 'R', 'C' } (stands for "dircache")
+
+     4-byte version number:
+       The current supported versions are 2, 3 and 4.
+
+     32-bit number of index entries.
+
+   - A number of sorted index entries (see below).
+
+   - Extensions
+
+     Extensions are identified by signature. Optional extensions can
+     be ignored if Git does not understand them.
+
+     Git currently supports cached tree and resolve undo extensions.
+
+     4-byte extension signature. If the first byte is 'A'..'Z' the
+     extension is optional and can be ignored.
+
+     32-bit size of the extension
+
+     Extension data
+
+   - 160-bit SHA-1 over the content of the index file before this
+     checksum.
+
+== Index entry
+
+  Index entries are sorted in ascending order on the name field,
+  interpreted as a string of unsigned bytes (i.e. memcmp() order, no
+  localization, no special casing of directory separator '/'). Entries
+  with the same name are sorted by their stage field.
+
+  32-bit ctime seconds, the last time a file's metadata changed
+    this is stat(2) data
+
+  32-bit ctime nanosecond fractions
+    this is stat(2) data
+
+  32-bit mtime seconds, the last time a file's data changed
+    this is stat(2) data
+
+  32-bit mtime nanosecond fractions
+    this is stat(2) data
+
+  32-bit dev
+    this is stat(2) data
+
+  32-bit ino
+    this is stat(2) data
+
+  32-bit mode, split into (high to low bits)
+
+    4-bit object type
+      valid values in binary are 1000 (regular file), 1010 (symbolic link)
+      and 1110 (gitlink)
+
+    3-bit unused
+
+    9-bit unix permission. Only 0755 and 0644 are valid for regular files.
+    Symbolic links and gitlinks have value 0 in this field.
+
+  32-bit uid
+    this is stat(2) data
+
+  32-bit gid
+    this is stat(2) data
+
+  32-bit file size
+    This is the on-disk size from stat(2), truncated to 32-bit.
+
+  160-bit SHA-1 for the represented object
+
+  A 16-bit 'flags' field split into (high to low bits)
+
+    1-bit assume-valid flag
+
+    1-bit extended flag (must be zero in version 2)
+
+    2-bit stage (during merge)
+
+    12-bit name length if the length is less than 0xFFF; otherwise 0xFFF
+    is stored in this field.
+
+  (Version 3 or later) A 16-bit field, only applicable if the
+  "extended flag" above is 1, split into (high to low bits).
+
+    1-bit reserved for future
+
+    1-bit skip-worktree flag (used by sparse checkout)
+
+    1-bit intent-to-add flag (used by "git add -N")
+
+    13-bit unused, must be zero
+
+  Entry path name (variable length) relative to top level directory
+    (without leading slash). '/' is used as path separator. The special
+    path components ".", ".." and ".git" (without quotes) are disallowed.
+    Trailing slash is also disallowed.
+
+    The exact encoding is undefined, but the '.' and '/' characters
+    are encoded in 7-bit ASCII and the encoding cannot contain a NUL
+    byte (iow, this is a UNIX pathname).
+
+  (Version 4) In version 4, the entry path name is prefix-compressed
+    relative to the path name for the previous entry (the very first
+    entry is encoded as if the path name for the previous entry is an
+    empty string).  At the beginning of an entry, an integer N in the
+    variable width encoding (the same encoding as the offset is encoded
+    for OFS_DELTA pack entries; see pack-format.txt) is stored, followed
+    by a NUL-terminated string S.  Removing N bytes from the end of the
+    path name for the previous entry, and replacing it with the string S
+    yields the path name for this entry.
+
+  1-8 nul bytes as necessary to pad the entry to a multiple of eight bytes
+  while keeping the name NUL-terminated.
+
+  (Version 4) In version 4, the padding after the pathname does not
+  exist.
+
+  Interpretation of index entries in split index mode is completely
+  different. See below for details.
+
+== Extensions
+
+=== Cached tree
+
+  Cached tree extension contains pre-computed hashes for trees that can
+  be derived from the index. It helps speed up tree object generation
+  from index for a new commit.
+
+  When a path is updated in index, the path must be invalidated and
+  removed from tree cache.
+
+  The signature for this extension is { 'T', 'R', 'E', 'E' }.
+
+  A series of entries fill the entire extension; each of which
+  consists of:
+
+  - NUL-terminated path component (relative to its parent directory);
+
+  - ASCII decimal number of entries in the index that is covered by the
+    tree this entry represents (entry_count);
+
+  - A space (ASCII 32);
+
+  - ASCII decimal number that represents the number of subtrees this
+    tree has;
+
+  - A newline (ASCII 10); and
+
+  - 160-bit object name for the object that would result from writing
+    this span of index as a tree.
+
+  An entry can be in an invalidated state and is represented by having
+  a negative number in the entry_count field. In this case, there is no
+  object name and the next entry starts immediately after the newline.
+  When writing an invalid entry, -1 should always be used as entry_count.
+
+  The entries are written out in the top-down, depth-first order.  The
+  first entry represents the root level of the repository, followed by the
+  first subtree---let's call this A---of the root level (with its name
+  relative to the root level), followed by the first subtree of A (with
+  its name relative to A), ...
+
+=== Resolve undo
+
+  A conflict is represented in the index as a set of higher stage entries.
+  When a conflict is resolved (e.g. with "git add path"), these higher
+  stage entries will be removed and a stage-0 entry with proper resolution
+  is added.
+
+  When these higher stage entries are removed, they are saved in the
+  resolve undo extension, so that conflicts can be recreated (e.g. with
+  "git checkout -m"), in case users want to redo a conflict resolution
+  from scratch.
+
+  The signature for this extension is { 'R', 'E', 'U', 'C' }.
+
+  A series of entries fill the entire extension; each of which
+  consists of:
+
+  - NUL-terminated pathname the entry describes (relative to the root of
+    the repository, i.e. full pathname);
+
+  - Three NUL-terminated ASCII octal numbers, entry mode of entries in
+    stage 1 to 3 (a missing stage is represented by "0" in this field);
+    and
+
+  - At most three 160-bit object names of the entry in stages from 1 to 3
+    (nothing is written for a missing stage).
+
+=== Split index
+
+  In split index mode, the majority of index entries could be stored
+  in a separate file. This extension records the changes to be made on
+  top of that to produce the final index.
+
+  The signature for this extension is { 'l', 'i', 'n', 'k' }.
+
+  The extension consists of:
+
+  - 160-bit SHA-1 of the shared index file. The shared index file path
+    is $GIT_DIR/sharedindex.<SHA-1>. If all 160 bits are zero, the
+    index does not require a shared index file.
+
+  - An ewah-encoded delete bitmap, each bit represents an entry in the
+    shared index. If a bit is set, its corresponding entry in the
+    shared index will be removed from the final index.  Note, because
+    a delete operation changes index entry positions, but we do need
+    original positions in replace phase, it's best to just mark
+    entries for removal, then do a mass deletion after replacement.
+
+  - An ewah-encoded replace bitmap, each bit represents an entry in
+    the shared index. If a bit is set, its corresponding entry in the
+    shared index will be replaced with an entry in this index
+    file. All replaced entries are stored in sorted order in this
+    index. The first "1" bit in the replace bitmap corresponds to the
+    first index entry, the second "1" bit to the second entry and so
+    on. Replaced entries may have empty path names to save space.
+
+  The remaining index entries after replaced ones will be added to the
+  final index. These added entries are also sorted by entry name then
+  stage.
+
+== Untracked cache
+
+  Untracked cache saves the untracked file list and necessary data to
+  verify the cache. The signature for this extension is { 'U', 'N',
+  'T', 'R' }.
+
+  The extension starts with
+
+  - A sequence of NUL-terminated strings, preceded by the size of the
+    sequence in variable width encoding. Each string describes the
+    environment where the cache can be used.
+
+  - Stat data of $GIT_DIR/info/exclude. See "Index entry" section from
+    ctime field until "file size".
+
+  - Stat data of core.excludesfile
+
+  - 32-bit dir_flags (see struct dir_struct)
+
+  - 160-bit SHA-1 of $GIT_DIR/info/exclude. Null SHA-1 means the file
+    does not exist.
+
+  - 160-bit SHA-1 of core.excludesfile. Null SHA-1 means the file does
+    not exist.
+
+  - NUL-terminated string of per-dir exclude file name. This usually
+    is ".gitignore".
+
+  - The number of following directory blocks, variable width
+    encoding. If this number is zero, the extension ends here with a
+    following NUL.
+
+  - A number of directory blocks in depth-first-search order, each
+    consists of
+
+    - The number of untracked entries, variable width encoding.
+
+    - The number of sub-directory blocks, variable width encoding.
+
+    - The directory name terminated by NUL.
+
+    - A number of untracked file/dir names terminated by NUL.
+
+The remaining data of each directory block is grouped by type:
+
+  - An ewah bitmap, the n-th bit marks whether the n-th directory has
+    valid untracked cache entries.
+
+  - An ewah bitmap, the n-th bit records "check-only" bit of
+    read_directory_recursive() for the n-th directory.
+
+  - An ewah bitmap, the n-th bit indicates whether SHA-1 and stat data
+    is valid for the n-th directory and exists in the next data.
+
+  - An array of stat data. The n-th data corresponds with the n-th
+    "one" bit in the previous ewah bitmap.
+
+  - An array of SHA-1. The n-th SHA-1 corresponds with the n-th "one" bit
+    in the previous ewah bitmap.
+

+Packfile transfer protocols
+===========================
+
+Git supports transferring data in packfiles over the ssh://, git://, http:// and
+file:// transports.  There exist two sets of protocols, one for pushing
+data from a client to a server and another for fetching data from a
+server to a client.  The three transports (ssh, git, file) use the same
+protocol to transfer data. http is documented in http-protocol.txt.
+
+The processes invoked in the canonical Git implementation are 'upload-pack'
+on the server side and 'fetch-pack' on the client side for fetching data;
+then 'receive-pack' on the server and 'send-pack' on the client for pushing
+data.  The protocol functions to have a server tell a client what is
+currently on the server, then for the two to negotiate the smallest amount
+of data to send in order to fully update one or the other.
+
+pkt-line Format
+---------------
+
+The descriptions below build on the pkt-line format described in
+protocol-common.txt. When the grammar indicate `PKT-LINE(...)`, unless
+otherwise noted the usual pkt-line LF rules apply: the sender SHOULD
+include a LF, but the receiver MUST NOT complain if it is not present.
+
+Transports
+----------
+There are three transports over which the packfile protocol is
+initiated.  The Git transport is a simple, unauthenticated server that
+takes the command (almost always 'upload-pack', though Git
+servers can be configured to be globally writable, in which 'receive-
+pack' initiation is also allowed) with which the client wishes to
+communicate and executes it and connects it to the requesting
+process.
+
+In the SSH transport, the client just runs the 'upload-pack'
+or 'receive-pack' process on the server over the SSH protocol and then
+communicates with that invoked process over the SSH connection.
+
+The file:// transport runs the 'upload-pack' or 'receive-pack'
+process locally and communicates with it over a pipe.
+
+Git Transport
+-------------
+
+The Git transport starts off by sending the command and repository
+on the wire using the pkt-line format, followed by a NUL byte and a
+hostname parameter, terminated by a NUL byte.
+
+   0032git-upload-pack /project.git\0host=myserver.com\0
+
+--
+   git-proto-request = request-command SP pathname NUL [ host-parameter NUL ]
+   request-command   = "git-upload-pack" / "git-receive-pack" /
+		       "git-upload-archive"   ; case sensitive
+   pathname          = *( %x01-ff ) ; exclude NUL
+   host-parameter    = "host=" hostname [ ":" port ]
+--
+
+Only host-parameter is allowed in the git-proto-request. Clients
+MUST NOT attempt to send additional parameters. It is used for the
+git-daemon name based virtual hosting.  See --interpolated-path
+option to git daemon, with the %H/%CH format characters.
+
+Basically what the Git client is doing to connect to an 'upload-pack'
+process on the server side over the Git protocol is this:
+
+   $ echo -e -n \
+     "0039git-upload-pack /schacon/gitbook.git\0host=example.com\0" |
+     nc -v example.com 9418
+
+If the server refuses the request for some reasons, it could abort
+gracefully with an error message.
+
+----
+  error-line     =  PKT-LINE("ERR" SP explanation-text)
+----
+
+
+SSH Transport
+-------------
+
+Initiating the upload-pack or receive-pack processes over SSH is
+executing the binary on the server via SSH remote execution.
+It is basically equivalent to running this:
+
+   $ ssh git.example.com "git-upload-pack '/project.git'"
+
+For a server to support Git pushing and pulling for a given user over
+SSH, that user needs to be able to execute one or both of those
+commands via the SSH shell that they are provided on login.  On some
+systems, that shell access is limited to only being able to run those
+two commands, or even just one of them.
+
+In an ssh:// format URI, it's absolute in the URI, so the '/' after
+the host name (or port number) is sent as an argument, which is then
+read by the remote git-upload-pack exactly as is, so it's effectively
+an absolute path in the remote filesystem.
+
+       git clone ssh://user@example.com/project.git
+		    |
+		    v
+    ssh user@example.com "git-upload-pack '/project.git'"
+
+In a "user@host:path" format URI, its relative to the user's home
+directory, because the Git client will run:
+
+     git clone user@example.com:project.git
+		    |
+		    v
+  ssh user@example.com "git-upload-pack 'project.git'"
+
+The exception is if a '~' is used, in which case
+we execute it without the leading '/'.
+
+      ssh://user@example.com/~alice/project.git,
+		     |
+		     v
+   ssh user@example.com "git-upload-pack '~alice/project.git'"
+
+A few things to remember here:
+
+- The "command name" is spelled with dash (e.g. git-upload-pack), but
+  this can be overridden by the client;
+
+- The repository path is always quoted with single quotes.
+
+Fetching Data From a Server
+---------------------------
+
+When one Git repository wants to get data that a second repository
+has, the first can 'fetch' from the second.  This operation determines
+what data the server has that the client does not then streams that
+data down to the client in packfile format.
+
+
+Reference Discovery
+-------------------
+
+When the client initially connects the server will immediately respond
+with a listing of each reference it has (all branches and tags) along
+with the object name that each reference currently points to.
+
+   $ echo -e -n "0039git-upload-pack /schacon/gitbook.git\0host=example.com\0" |
+      nc -v example.com 9418
+   00887217a7c7e582c46cec22a130adf4b9d7d950fba0 HEAD\0multi_ack thin-pack
+		side-band side-band-64k ofs-delta shallow no-progress include-tag

+   003fe92df48743b7bc7d26bcaabfddde0a1e20cae47c refs/tags/v1.0^{}
+   0000
+
+The returned response is a pkt-line stream describing each ref and
+its current value.  The stream MUST be sorted by name according to
+the C locale ordering.
+
+If HEAD is a valid ref, HEAD MUST appear as the first advertised
+ref.  If HEAD is not a valid ref, HEAD MUST NOT appear in the
+advertisement list at all, but other refs may still appear.
+
+The stream MUST include capability declarations behind a NUL on the
+first ref. The peeled value of a ref (that is "ref^{}") MUST be
+immediately after the ref itself, if presented. A conforming server
+MUST peel the ref if it's an annotated tag.
+
+----
+  advertised-refs  =  (no-refs / list-of-refs)
+		      *shallow
+		      flush-pkt

+----
+
+Server and client MUST use lowercase for obj-id, both MUST treat obj-id
+as case-insensitive.
+
+See protocol-capabilities.txt for a list of allowed server capabilities
+and descriptions.
+
+Packfile Negotiation
+--------------------
+After reference and capabilities discovery, the client can decide to
+terminate the connection by sending a flush-pkt, telling the server it can
+now gracefully terminate, and disconnect, when it does not need any pack
+data. This can happen with the ls-remote command, and also can happen when
+the client already is up-to-date.
+
+Otherwise, it enters the negotiation phase, where the client and
+server determine what the minimal packfile necessary for transport is,
+by telling the server what objects it wants, its shallow objects
+(if any), and the maximum commit depth it wants (if any).  The client
+will also send a list of the capabilities it wants to be in effect,
+out of what the server said it could do with the first 'want' line.
+
+----
+  upload-request    =  want-list
+		       *shallow-line
+		       *1depth-request
+		       flush-pkt
+
+  want-list         =  first-want
+		       *additional-want
+
+  shallow-line      =  PKT-LINE("shallow" SP obj-id)
+
+  depth-request     =  PKT-LINE("deepen" SP depth)
+
+  first-want        =  PKT-LINE("want" SP obj-id SP capability-list)
+  additional-want   =  PKT-LINE("want" SP obj-id)
+
+  depth             =  1*DIGIT
+----
+
+Clients MUST send all the obj-ids it wants from the reference
+discovery phase as 'want' lines. Clients MUST send at least one
+'want' command in the request body. Clients MUST NOT mention an
+obj-id in a 'want' command which did not appear in the response
+obtained through ref discovery.
+
+The client MUST write all obj-ids which it only has shallow copies
+of (meaning that it does not have the parents of a commit) as
+'shallow' lines so that the server is aware of the limitations of
+the client's history.
+
+The client now sends the maximum commit history depth it wants for
+this transaction, which is the number of commits it wants from the
+tip of the history, if any, as a 'deepen' line.  A depth of 0 is the
+same as not making a depth request. The client does not want to receive
+any commits beyond this depth, nor does it want objects needed only to
+complete those commits. Commits whose parents are not received as a
+result are defined as shallow and marked as such in the server. This
+information is sent back to the client in the next step.
+
+Once all the 'want's and 'shallow's (and optional 'deepen') are
+transferred, clients MUST send a flush-pkt, to tell the server side
+that it is done sending the list.
+
+Otherwise, if the client sent a positive depth request, the server
+will determine which commits will and will not be shallow and
+send this information to the client. If the client did not request
+a positive depth, this step is skipped.
+
+----
+  shallow-update   =  *shallow-line
+		      *unshallow-line
+		      flush-pkt
+
+  shallow-line     =  PKT-LINE("shallow" SP obj-id)
+
+  unshallow-line   =  PKT-LINE("unshallow" SP obj-id)
+----
+
+If the client has requested a positive depth, the server will compute
+the set of commits which are no deeper than the desired depth. The set
+of commits start at the client's wants.
+
+The server writes 'shallow' lines for each
+commit whose parents will not be sent as a result. The server writes
+an 'unshallow' line for each commit which the client has indicated is
+shallow, but is no longer shallow at the currently requested depth
+(that is, its parents will now be sent). The server MUST NOT mark
+as unshallow anything which the client has not indicated was shallow.
+
+Now the client will send a list of the obj-ids it has using 'have'
+lines, so the server can make a packfile that only contains the objects
+that the client needs. In multi_ack mode, the canonical implementation
+will send up to 32 of these at a time, then will send a flush-pkt. The
+canonical implementation will skip ahead and send the next 32 immediately,
+so that there is always a block of 32 "in-flight on the wire" at a time.
+
+----
+  upload-haves      =  have-list
+		       compute-end
+
+  have-list         =  *have-line
+  have-line         =  PKT-LINE("have" SP obj-id)
+  compute-end       =  flush-pkt / PKT-LINE("done")
+----
+
+If the server reads 'have' lines, it then will respond by ACKing any
+of the obj-ids the client said it had that the server also has. The
+server will ACK obj-ids differently depending on which ack mode is
+chosen by the client.
+
+In multi_ack mode:
+
+  * the server will respond with 'ACK obj-id continue' for any common
+    commits.
+
+  * once the server has found an acceptable common base commit and is
+    ready to make a packfile, it will blindly ACK all 'have' obj-ids
+    back to the client.
+
+  * the server will then send a 'NACK' and then wait for another response
+    from the client - either a 'done' or another list of 'have' lines.
+
+In multi_ack_detailed mode:
+
+  * the server will differentiate the ACKs where it is signaling
+    that it is ready to send data with 'ACK obj-id ready' lines, and
+    signals the identified common commits with 'ACK obj-id common' lines.
+
+Without either multi_ack or multi_ack_detailed:
+
+ * upload-pack sends "ACK obj-id" on the first common object it finds.
+   After that it says nothing until the client gives it a "done".
+
+ * upload-pack sends "NAK" on a flush-pkt if no common object
+   has been found yet.  If one has been found, and thus an ACK
+   was already sent, it's silent on the flush-pkt.
+
+After the client has gotten enough ACK responses that it can determine
+that the server has enough information to send an efficient packfile
+(in the canonical implementation, this is determined when it has received
+enough ACKs that it can color everything left in the --date-order queue
+as common with the server, or the --date-order queue is empty), or the
+client determines that it wants to give up (in the canonical implementation,
+this is determined when the client sends 256 'have' lines without getting
+any of them ACKed by the server - meaning there is nothing in common and
+the server should just send all of its objects), then the client will send
+a 'done' command.  The 'done' command signals to the server that the client
+is ready to receive its packfile data.
+
+However, the 256 limit *only* turns on in the canonical client
+implementation if we have received at least one "ACK %s continue"
+during a prior round.  This helps to ensure that at least one common
+ancestor is found before we give up entirely.
+
+Once the 'done' line is read from the client, the server will either
+send a final 'ACK obj-id' or it will send a 'NAK'. 'obj-id' is the object
+name of the last commit determined to be common. The server only sends
+ACK after 'done' if there is at least one common base and multi_ack or
+multi_ack_detailed is enabled. The server always sends NAK after 'done'
+if there is no common base found.
+
+Then the server will start sending its packfile data.
+
+----
+  server-response = *ack_multi ack / nak
+  ack_multi       = PKT-LINE("ACK" SP obj-id ack_status)
+  ack_status      = "continue" / "common" / "ready"
+  ack             = PKT-LINE("ACK" SP obj-id)

+   S: [PACKFILE]
+----
+
+
+Packfile Data
+-------------
+
+Now that the client and server have finished negotiation about what
+the minimal amount of data that needs to be sent to the client is, the server
+will construct and send the required data in packfile format.
+
+See pack-format.txt for what the packfile itself actually looks like.
+
+If 'side-band' or 'side-band-64k' capabilities have been specified by
+the client, the server will send the packfile data multiplexed.
+
+Each packet starting with the packet-line length of the amount of data
+that follows, followed by a single byte specifying the sideband the
+following data is coming in on.
+
+In 'side-band' mode, it will send up to 999 data bytes plus 1 control
+code, for a total of up to 1000 bytes in a pkt-line.  In 'side-band-64k'
+mode it will send up to 65519 data bytes plus 1 control code, for a
+total of up to 65520 bytes in a pkt-line.
+
+The sideband byte will be a '1', '2' or a '3'. Sideband '1' will contain
+packfile data, sideband '2' will be used for progress information that the
+client will generally print to stderr and sideband '3' is used for error
+information.
+
+If no 'side-band' capability was specified, the server will stream the
+entire packfile without multiplexing.
+
+
+Pushing Data To a Server
+------------------------
+
+Pushing data to a server will invoke the 'receive-pack' process on the
+server, which will allow the client to tell it which references it should
+update and then send all the data the server will need for those new
+references to be complete.  Once all the data is received and validated,
+the server will then update its references to what the client specified.
+
+Authentication
+--------------
+
+The protocol itself contains no authentication mechanisms.  That is to be
+handled by the transport, such as SSH, before the 'receive-pack' process is
+invoked.  If 'receive-pack' is configured over the Git transport, those
+repositories will be writable by anyone who can access that port (9418) as
+that transport is unauthenticated.
+
+Reference Discovery
+-------------------
+
+The reference discovery phase is done nearly the same way as it is in the
+fetching protocol. Each reference obj-id and name on the server is sent
+in packet-line format to the client, followed by a flush-pkt.  The only
+real difference is that the capability listing is different - the only
+possible values are 'report-status', 'delete-refs' and 'ofs-delta'.
+
+Reference Update Request and Packfile Transfer
+----------------------------------------------
+
+Once the client knows what references the server is at, it can send a
+list of reference update requests.  For each reference on the server
+that it wants to update, it sends a line listing the obj-id currently on
+the server, the obj-id the client would like to update it to and the name
+of the reference.
+
+This list is followed by a flush-pkt and then the packfile that should
+contain all the objects that the server will need to complete the new
+references.
+
+----
+  update-request    =  *shallow ( command-list | push-cert ) [packfile]
+
+  shallow           =  PKT-LINE("shallow" SP obj-id)
+
+  command-list      =  PKT-LINE(command NUL capability-list)
+		       *PKT-LINE(command)
+		       flush-pkt
+
+  command           =  create / delete / update
+  create            =  zero-id SP new-id  SP name
+  delete            =  old-id  SP zero-id SP name
+  update            =  old-id  SP new-id  SP name
+
+  old-id            =  obj-id
+  new-id            =  obj-id
+
+  push-cert         = PKT-LINE("push-cert" NUL capability-list LF)
+		      PKT-LINE("certificate version 0.1" LF)
+		      PKT-LINE("pusher" SP ident LF)
+		      PKT-LINE("pushee" SP url LF)
+		      PKT-LINE("nonce" SP nonce LF)
+		      PKT-LINE(LF)
+		      *PKT-LINE(command LF)
+		      *PKT-LINE(gpg-signature-lines LF)
+		      PKT-LINE("push-cert-end" LF)
+
+  packfile          = "PACK" 28*(OCTET)
+----
+
+If the receiving end does not support delete-refs, the sending end MUST
+NOT ask for delete command.
+
+If the receiving end does not support push-cert, the sending end
+MUST NOT send a push-cert command.  When a push-cert command is
+sent, command-list MUST NOT be sent; the commands recorded in the
+push certificate is used instead.
+
+The packfile MUST NOT be sent if the only command used is 'delete'.
+
+A packfile MUST be sent if either create or update command is used,
+even if the server already has all the necessary objects.  In this
+case the client MUST send an empty packfile.   The only time this
+is likely to happen is if the client is creating
+a new branch or a tag that points to an existing obj-id.
+
+The server will receive the packfile, unpack it, then validate each
+reference that is being updated that it hasn't changed while the request
+was being processed (the obj-id is still the same as the old-id), and
+it will run any update hooks to make sure that the update is acceptable.
+If all of that is fine, the server will then update the references.
+
+Push Certificate
+----------------
+
+A push certificate begins with a set of header lines.  After the
+header and an empty line, the protocol commands follow, one per
+line. Note that the the trailing LF in push-cert PKT-LINEs is _not_
+optional; it must be present.
+
+Currently, the following header fields are defined:
+
+`pusher` ident::
+	Identify the GPG key in "Human Readable Name <email@address>"
+	format.
+
+`pushee` url::
+	The repository URL (anonymized, if the URL contains
+	authentication material) the user who ran `git push`
+	intended to push into.
+
+`nonce` nonce::
+	The 'nonce' string the receiving repository asked the
+	pushing user to include in the certificate, to prevent
+	replay attacks.
+
+The GPG signature lines are a detached signature for the contents
+recorded in the push certificate before the signature block begins.
+The detached signature is used to certify that the commands were
+given by the pusher, who must be the signer.
+
+Report Status
+-------------
+
+After receiving the pack data from the sender, the receiver sends a
+report if 'report-status' capability is in effect.
+It is a short listing of what happened in that update.  It will first
+list the status of the packfile unpacking as either 'unpack ok' or
+'unpack [error]'.  Then it will list the status for each of the references
+that it tried to update.  Each line is either 'ok [refname]' if the
+update was successful, or 'ng [refname] [error]' if the update was not.
+
+----
+  report-status     = unpack-status
+		      1*(command-status)
+		      flush-pkt
+
+  unpack-status     = PKT-LINE("unpack" SP unpack-result)
+  unpack-result     = "ok" / error-msg
+
+  command-status    = command-ok / command-fail
+  command-ok        = PKT-LINE("ok" SP refname)
+  command-fail      = PKT-LINE("ng" SP refname SP error-msg)
+
+  error-msg         = 1*(OCTECT) ; where not "ok"
+----
+
+Updates can be unsuccessful for a number of reasons.  The reference can have
+changed since the reference discovery phase was originally sent, meaning
+someone pushed in the meantime.  The reference being pushed could be a
+non-fast-forward reference and the update hooks or configuration could be
+set to not allow that, etc.  Also, some references can be updated while others
+can be rejected.
+
+An example client/server communication might look like this:

+Git Protocol Capabilities
+=========================
+
+Servers SHOULD support all capabilities defined in this document.
+
+On the very first line of the initial server response of either
+receive-pack and upload-pack the first reference is followed by
+a NUL byte and then a list of space delimited server capabilities.
+These allow the server to declare what it can and cannot support
+to the client.
+
+Client will then send a space separated list of capabilities it wants
+to be in effect. The client MUST NOT ask for capabilities the server
+did not say it supports.
+
+Server MUST diagnose and abort if capabilities it does not understand
+was sent.  Server MUST NOT ignore capabilities that client requested
+and server advertised.  As a consequence of these rules, server MUST
+NOT advertise capabilities it does not understand.
+
+The 'atomic', 'report-status', 'delete-refs', 'quiet', and 'push-cert'
+capabilities are sent and recognized by the receive-pack (push to server)
+process.
+
+The 'ofs-delta' and 'side-band-64k' capabilities are sent and recognized
+by both upload-pack and receive-pack protocols.  The 'agent' capability
+may optionally be sent in both protocols.
+
+All other capabilities are only recognized by the upload-pack (fetch
+from server) process.
+
+multi_ack
+---------
+
+The 'multi_ack' capability allows the server to return "ACK obj-id
+continue" as soon as it finds a commit that it can use as a common
+base, between the client's wants and the client's have set.
+
+By sending this early, the server can potentially head off the client
+from walking any further down that particular branch of the client's
+repository history.  The client may still need to walk down other
+branches, sending have lines for those, until the server has a
+complete cut across the DAG, or the client has said "done".
+
+Without multi_ack, a client sends have lines in --date-order until
+the server has found a common base.  That means the client will send
+have lines that are already known by the server to be common, because
+they overlap in time with another branch that the server hasn't found
+a common base on yet.
+
+For example suppose the client has commits in caps that the server
+doesn't and the server has commits in lower case that the client
+doesn't, as in the following diagram:
+
+       +---- u ---------------------- x
+      /              +----- y
+     /              /
+    a -- b -- c -- d -- E -- F
+       \
+	+--- Q -- R -- S
+
+If the client wants x,y and starts out by saying have F,S, the server
+doesn't know what F,S is.  Eventually the client says "have d" and
+the server sends "ACK d continue" to let the client know to stop
+walking down that line (so don't send c-b-a), but it's not done yet,
+it needs a base for x. The client keeps going with S-R-Q, until a
+gets reached, at which point the server has a clear base and it all
+ends.
+
+Without multi_ack the client would have sent that c-b-a chain anyway,
+interleaved with S-R-Q.
+
+multi_ack_detailed
+------------------
+This is an extension of multi_ack that permits client to better
+understand the server's in-memory state. See pack-protocol.txt,
+section "Packfile Negotiation" for more information.
+
+no-done
+-------
+This capability should only be used with the smart HTTP protocol. If
+multi_ack_detailed and no-done are both present, then the sender is
+free to immediately send a pack following its first "ACK obj-id ready"
+message.
+
+Without no-done in the smart HTTP protocol, the server session would
+end and the client has to make another trip to send "done" before
+the server can send the pack. no-done removes the last round and
+thus slightly reduces latency.
+
+thin-pack
+---------
+
+A thin pack is one with deltas which reference base objects not
+contained within the pack (but are known to exist at the receiving
+end). This can reduce the network traffic significantly, but it
+requires the receiving end to know how to "thicken" these packs by
+adding the missing bases to the pack.
+
+The upload-pack server advertises 'thin-pack' when it can generate
+and send a thin pack. A client requests the 'thin-pack' capability
+when it understands how to "thicken" it, notifying the server that
+it can receive such a pack. A client MUST NOT request the
+'thin-pack' capability if it cannot turn a thin pack into a
+self-contained pack.
+
+Receive-pack, on the other hand, is assumed by default to be able to
+handle thin packs, but can ask the client not to use the feature by
+advertising the 'no-thin' capability. A client MUST NOT send a thin
+pack if the server advertises the 'no-thin' capability.
+
+The reasons for this asymmetry are historical. The receive-pack
+program did not exist until after the invention of thin packs, so
+historically the reference implementation of receive-pack always
+understood thin packs. Adding 'no-thin' later allowed receive-pack
+to disable the feature in a backwards-compatible manner.
+
+
+side-band, side-band-64k
+------------------------
+
+This capability means that server can send, and client understand multiplexed
+progress reports and error info interleaved with the packfile itself.
+
+These two options are mutually exclusive. A modern client always
+favors 'side-band-64k'.
+
+Either mode indicates that the packfile data will be streamed broken
+up into packets of up to either 1000 bytes in the case of 'side_band',
+or 65520 bytes in the case of 'side_band_64k'. Each packet is made up
+of a leading 4-byte pkt-line length of how much data is in the packet,
+followed by a 1-byte stream code, followed by the actual data.
+
+The stream code can be one of:
+
+ 1 - pack data
+ 2 - progress messages
+ 3 - fatal error message just before stream aborts
+
+The "side-band-64k" capability came about as a way for newer clients
+that can handle much larger packets to request packets that are
+actually crammed nearly full, while maintaining backward compatibility
+for the older clients.
+
+Further, with side-band and its up to 1000-byte messages, it's actually
+999 bytes of payload and 1 byte for the stream code. With side-band-64k,
+same deal, you have up to 65519 bytes of data and 1 byte for the stream
+code.
+
+The client MUST send only maximum of one of "side-band" and "side-
+band-64k".  Server MUST diagnose it as an error if client requests
+both.
+
+ofs-delta
+---------
+
+Server can send, and client understand PACKv2 with delta referring to
+its base by position in pack rather than by an obj-id.  That is, they can
+send/read OBJ_OFS_DELTA (aka type 6) in a packfile.
+
+agent
+-----
+
+The server may optionally send a capability of the form `agent=X` to
+notify the client that the server is running version `X`. The client may
+optionally return its own agent string by responding with an `agent=Y`
+capability (but it MUST NOT do so if the server did not mention the
+agent capability). The `X` and `Y` strings may contain any printable
+ASCII characters except space (i.e., the byte range 32 < x < 127), and
+are typically of the form "package/version" (e.g., "git/1.8.3.1"). The
+agent strings are purely informative for statistics and debugging
+purposes, and MUST NOT be used to programmatically assume the presence
+or absence of particular features.
+
+shallow
+-------
+
+This capability adds "deepen", "shallow" and "unshallow" commands to
+the  fetch-pack/upload-pack protocol so clients can request shallow
+clones.
+
+no-progress
+-----------
+
+The client was started with "git clone -q" or something, and doesn't
+want that side band 2.  Basically the client just says "I do not
+wish to receive stream 2 on sideband, so do not send it to me, and if
+you did, I will drop it on the floor anyway".  However, the sideband
+channel 3 is still used for error responses.
+
+include-tag
+-----------
+
+The 'include-tag' capability is about sending annotated tags if we are
+sending objects they point to.  If we pack an object to the client, and
+a tag object points exactly at that object, we pack the tag object too.
+In general this allows a client to get all new annotated tags when it
+fetches a branch, in a single network connection.
+
+Clients MAY always send include-tag, hardcoding it into a request when
+the server advertises this capability. The decision for a client to
+request include-tag only has to do with the client's desires for tag
+data, whether or not a server had advertised objects in the
+refs/tags/* namespace.
+
+Servers MUST pack the tags if their referrant is packed and the client
+has requested include-tags.
+
+Clients MUST be prepared for the case where a server has ignored
+include-tag and has not actually sent tags in the pack.  In such
+cases the client SHOULD issue a subsequent fetch to acquire the tags
+that include-tag would have otherwise given the client.
+
+The server SHOULD send include-tag, if it supports it, regardless
+of whether or not there are tags available.
+
+report-status
+-------------
+
+The receive-pack process can receive a 'report-status' capability,
+which tells it that the client wants a report of what happened after
+a packfile upload and reference update.  If the pushing client requests
+this capability, after unpacking and updating references the server
+will respond with whether the packfile unpacked successfully and if
+each reference was updated successfully.  If any of those were not
+successful, it will send back an error message.  See pack-protocol.txt
+for example messages.
+
+delete-refs
+-----------
+
+If the server sends back the 'delete-refs' capability, it means that
+it is capable of accepting a zero-id value as the target
+value of a reference update.  It is not sent back by the client, it
+simply informs the client that it can be sent zero-id values
+to delete references.
+
+quiet
+-----
+
+If the receive-pack server advertises the 'quiet' capability, it is
+capable of silencing human-readable progress output which otherwise may
+be shown when processing the received pack. A send-pack client should
+respond with the 'quiet' capability to suppress server-side progress
+reporting if the local progress reporting is also being suppressed
+(e.g., via `push -q`, or if stderr does not go to a tty).
+
+atomic
+------
+
+If the server sends the 'atomic' capability it is capable of accepting
+atomic pushes. If the pushing client requests this capability, the server
+will update the refs in one atomic transaction. Either all refs are
+updated or none.
+
+allow-tip-sha1-in-want
+----------------------
+
+If the upload-pack server advertises this capability, fetch-pack may
+send "want" lines with SHA-1s that exist at the server but are not
+advertised by upload-pack.
+
+allow-reachable-sha1-in-want
+----------------------------
+
+If the upload-pack server advertises this capability, fetch-pack may
+send "want" lines with SHA-1s that exist at the server but are not
+advertised by upload-pack.
+
+push-cert=<nonce>
+-----------------
+
+The receive-pack server that advertises this capability is willing
+to accept a signed push certificate, and asks the <nonce> to be
+included in the push certificate.  A send-pack client MUST NOT
+send a push-cert packet unless the receive-pack server advertises
+this capability.

+Documentation Common to Pack and Http Protocols
+===============================================
+
+ABNF Notation
+-------------
+
+ABNF notation as described by RFC 5234 is used within the protocol documents,
+except the following replacement core rules are used:
+----
+  HEXDIG    =  DIGIT / "a" / "b" / "c" / "d" / "e" / "f"
+----
+
+We also define the following common rules:
+----
+  NUL       =  %x00
+  zero-id   =  40*"0"
+  obj-id    =  40*(HEXDIGIT)
+
+  refname  =  "HEAD"
+  refname /=  "refs/" <see discussion below>
+----
+
+A refname is a hierarchical octet string beginning with "refs/" and
+not violating the 'git-check-ref-format' command's validation rules.
+More specifically, they:
+
+. They can include slash `/` for hierarchical (directory)
+  grouping, but no slash-separated component can begin with a
+  dot `.`.
+
+. They must contain at least one `/`. This enforces the presence of a
+  category like `heads/`, `tags/` etc. but the actual names are not
+  restricted.
+
+. They cannot have two consecutive dots `..` anywhere.
+
+. They cannot have ASCII control characters (i.e. bytes whose
+  values are lower than \040, or \177 `DEL`), space, tilde `~`,
+  caret `^`, colon `:`, question-mark `?`, asterisk `*`,
+  or open bracket `[` anywhere.
+
+. They cannot end with a slash `/` or a dot `.`.
+
+. They cannot end with the sequence `.lock`.
+
+. They cannot contain a sequence `@{`.
+
+. They cannot contain a `\\`.
+
+
+pkt-line Format
+---------------
+
+Much (but not all) of the payload is described around pkt-lines.
+
+A pkt-line is a variable length binary string.  The first four bytes
+of the line, the pkt-len, indicates the total length of the line,
+in hexadecimal.  The pkt-len includes the 4 bytes used to contain
+the length's hexadecimal representation.
+
+A pkt-line MAY contain binary data, so implementors MUST ensure
+pkt-line parsing/formatting routines are 8-bit clean.
+
+A non-binary line SHOULD BE terminated by an LF, which if present
+MUST be included in the total length. Receivers MUST treat pkt-lines
+with non-binary data the same whether or not they contain the trailing
+LF (stripping the LF if present, and not complaining when it is
+missing).
+
+The maximum length of a pkt-line's data component is 65520 bytes.
+Implementations MUST NOT send pkt-line whose length exceeds 65524
+(65520 bytes of payload + 4 bytes of length data).
+
+Implementations SHOULD NOT send an empty pkt-line ("0004").
+
+A pkt-line with a length field of 0 ("0000"), called a flush-pkt,
+is a special case and MUST be handled differently than an empty
+pkt-line ("0004").
+
+----
+  pkt-line     =  data-pkt / flush-pkt
+
+  data-pkt     =  pkt-len pkt-payload
+  pkt-len      =  4*(HEXDIG)
+  pkt-payload  =  (pkt-len - 4)*(OCTET)
+
+  flush-pkt    = "0000"
+----
+
+Examples (as C-style strings):

+Shallow commits
+===============
+
+.Definition
+*********************************************************
+Shallow commits do have parents, but not in the shallow
+repo, and therefore grafts are introduced pretending that
+these commits have no parents.
+*********************************************************
+
+The basic idea is to write the SHA-1s of shallow commits into
+$GIT_DIR/shallow, and handle its contents like the contents
+of $GIT_DIR/info/grafts (with the difference that shallow
+cannot contain parent information).
+
+This information is stored in a new file instead of grafts, or
+even the config, since the user should not touch that file
+at all (even throughout development of the shallow clone, it
+was never manually edited!).
+
+Each line contains exactly one SHA-1. When read, a commit_graft
+will be constructed, which has nr_parent < 0 to make it easier
+to discern from user provided grafts.
+
+Since fsck-objects relies on the library to read the objects,
+it honours shallow commits automatically.
+
+There are some unfinished ends of the whole shallow business:
+
+- maybe we have to force non-thin packs when fetching into a
+  shallow repo (ATM they are forced non-thin).
+
+- A special handling of a shallow upstream is needed. At some
+  stage, upload-pack has to check if it sends a shallow commit,
+  and it should send that information early (or fail, if the
+  client does not support shallow repositories). There is no
+  support at all for this in this patch series.
+
+- Instead of locking $GIT_DIR/shallow at the start, just
+  the timestamp of it is noted, and when it comes to writing it,
+  a check is performed if the mtime is still the same, dying if
+  it is not.
+
+- It is unclear how "push into/from a shallow repo" should behave.
+
+- If you deepen a history, you'd want to get the tags of the
+  newly stored (but older!) commits. This does not work right now.
+
+To make a shallow clone, you can call "git-clone --depth 20 repo".
+The result contains only commit chains with a length of at most 20.
+It also writes an appropriate $GIT_DIR/shallow.
+
+You can deepen a shallow repository with "git-fetch --depth 20
+repo branch", which will fetch branch from repo, but stop at depth
+20, updating $GIT_DIR/shallow.
+
+The special depth 2147483647 (or 0x7fffffff, the largest positive
+number a signed 32-bit integer can contain) means infinite depth.

-A tutorial introduction to git: part two
-========================================
-
-You should work through link:tutorial.html[A tutorial introduction to
-git] before reading this tutorial.
-
-The goal of this tutorial is to introduce two fundamental pieces of
-git's architecture--the object database and the index file--and to
-provide the reader with everything necessary to understand the rest
-of the git documentation.
-
-The git object database
------------------------
-
-Let's start a new project and create a small amount of history:
-
-------------------------------------------------
-$ mkdir test-project
-$ cd test-project
-$ git init
-Initialized empty Git repository in .git/
-$ echo 'hello world' > file.txt
-$ git add .
-$ git commit -a -m "initial commit"
-Created initial commit 54196cc2703dc165cbd373a65a4dcf22d50ae7f7
- create mode 100644 file.txt
-$ echo 'hello world!' >file.txt
-$ git commit -a -m "add emphasis"
-Created commit c4d59f390b9cfd4318117afde11d601c1085f241
-------------------------------------------------
-
-What are the 40 digits of hex that git responded to the commit with?
-
-We saw in part one of the tutorial that commits have names like this.
-It turns out that every object in the git history is stored under
-such a 40-digit hex name.  That name is the SHA1 hash of the object's
-contents; among other things, this ensures that git will never store
-the same data twice (since identical data is given an identical SHA1
-name), and that the contents of a git object will never change (since
-that would change the object's name as well).
-
-It is expected that the content of the commit object you created while
-following the example above generates a different SHA1 hash than
-the one shown above because the commit object records the time when
-it was created and the name of the person performing the commit.
-
-We can ask git about this particular object with the cat-file
-command. Don't copy the 40 hex digits from this example but use those
-from your own version. Note that you can shorten it to only a few
-characters to save yourself typing all 40 hex digits:
-
-------------------------------------------------
-$ git-cat-file -t 54196cc2
-commit
-$ git-cat-file commit 54196cc2
-tree 92b8b694ffb1675e5975148e1121810081dbdffe
-author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-
-initial commit
-------------------------------------------------
-
-A tree can refer to one or more "blob" objects, each corresponding to
-a file.  In addition, a tree can also refer to other tree objects,
-thus creating a directory hierarchy.  You can examine the contents of
-any tree using ls-tree (remember that a long enough initial portion
-of the SHA1 will also work):
-
-------------------------------------------------
-$ git ls-tree 92b8b694
-100644 blob 3b18e512dba79e4c8300dd08aeb37f8e728b8dad    file.txt
-------------------------------------------------
-
-Thus we see that this tree has one file in it.  The SHA1 hash is a
-reference to that file's data:
-
-------------------------------------------------
-$ git cat-file -t 3b18e512
-blob
-------------------------------------------------
-
-A "blob" is just file data, which we can also examine with cat-file:
-
-------------------------------------------------
-$ git cat-file blob 3b18e512
-hello world
-------------------------------------------------
-
-Note that this is the old file data; so the object that git named in
-its response to the initial tree was a tree with a snapshot of the
-directory state that was recorded by the first commit.
-
-All of these objects are stored under their SHA1 names inside the git
-directory:
-
-------------------------------------------------
-$ find .git/objects/
-.git/objects/
-.git/objects/pack
-.git/objects/info
-.git/objects/3b
-.git/objects/3b/18e512dba79e4c8300dd08aeb37f8e728b8dad
-.git/objects/92
-.git/objects/92/b8b694ffb1675e5975148e1121810081dbdffe

-.git/objects/c4
-.git/objects/c4/d59f390b9cfd4318117afde11d601c1085f241
-------------------------------------------------
-
-and the contents of these files is just the compressed data plus a
-header identifying their length and their type.  The type is either a
-blob, a tree, a commit, or a tag.
-
-The simplest commit to find is the HEAD commit, which we can find
-from .git/HEAD:
-
-------------------------------------------------
-$ cat .git/HEAD
-ref: refs/heads/master
-------------------------------------------------
-
-As you can see, this tells us which branch we're currently on, and it
-tells us this by naming a file under the .git directory, which itself
-contains a SHA1 name referring to a commit object, which we can
-examine with cat-file:
-
-------------------------------------------------
-$ cat .git/refs/heads/master
-c4d59f390b9cfd4318117afde11d601c1085f241
-$ git cat-file -t c4d59f39

-$ git cat-file commit c4d59f39

-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143418702 -0500
-
-add emphasis
-------------------------------------------------
-
-The "tree" object here refers to the new state of the tree:
-
-------------------------------------------------
-$ git ls-tree d0492b36
-100644 blob a0423896973644771497bdc03eb99d5281615b51    file.txt
-$ git cat-file blob a0423896
-hello world!
-------------------------------------------------
-
-and the "parent" object refers to the previous commit:
-
-------------------------------------------------
-$ git-cat-file commit 54196cc2
-tree 92b8b694ffb1675e5975148e1121810081dbdffe
-author J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
-
-initial commit
-------------------------------------------------
-
-The tree object is the tree we examined first, and this commit is
-unusual in that it lacks any parent.
-
-Most commits have only one parent, but it is also common for a commit
-to have multiple parents.   In that case the commit represents a
-merge, with the parent references pointing to the heads of the merged
-branches.
-
-Besides blobs, trees, and commits, the only remaining type of object
-is a "tag", which we won't discuss here; refer to gitlink:git-tag[1]
-for details.
-
-So now we know how git uses the object database to represent a
-project's history:
-
-  * "commit" objects refer to "tree" objects representing the
-    snapshot of a directory tree at a particular point in the
-    history, and refer to "parent" commits to show how they're
-    connected into the project history.
-  * "tree" objects represent the state of a single directory,
-    associating directory names to "blob" objects containing file
-    data and "tree" objects containing subdirectory information.
-  * "blob" objects contain file data without any other structure.
-  * References to commit objects at the head of each branch are
-    stored in files under .git/refs/heads/.
-  * The name of the current branch is stored in .git/HEAD.
-
-Note, by the way, that lots of commands take a tree as an argument.
-But as we can see above, a tree can be referred to in many different
-ways--by the SHA1 name for that tree, by the name of a commit that
-refers to the tree, by the name of a branch whose head refers to that
-tree, etc.--and most such commands can accept any of these names.
-
-In command synopses, the word "tree-ish" is sometimes used to
-designate such an argument.
-
-The index file
---------------
-
-The primary tool we've been using to create commits is "git commit
--a", which creates a commit including every change you've made to
-your working tree.  But what if you want to commit changes only to
-certain files?  Or only certain changes to certain files?
-
-If we look at the way commits are created under the cover, we'll see
-that there are more flexible ways creating commits.
-
-Continuing with our test-project, let's modify file.txt again:
-
-------------------------------------------------
-$ echo "hello world, again" >>file.txt
-------------------------------------------------
-
-but this time instead of immediately making the commit, let's take an
-intermediate step, and ask for diffs along the way to keep track of
-what's happening:
-
-------------------------------------------------
-$ git diff
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-$ git add file.txt
-$ git diff
-------------------------------------------------
-
-The last diff is empty, but no new commits have been made, and the
-head still doesn't contain the new line:
-
-------------------------------------------------
-$ git-diff HEAD
-diff --git a/file.txt b/file.txt
-index a042389..513feba 100644
---- a/file.txt
-+++ b/file.txt
-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-------------------------------------------------
-
-So "git diff" is comparing against something other than the head.
-The thing that it's comparing against is actually the index file,
-which is stored in .git/index in a binary format, but whose contents
-we can examine with ls-files:
-
-------------------------------------------------
-$ git ls-files --stage
-100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
-$ git cat-file -t 513feba2
-blob
-$ git cat-file blob 513feba2
-hello world!
-hello world, again
-------------------------------------------------
-
-So what our "git add" did was store a new blob and then put
-a reference to it in the index file.  If we modify the file again,
-we'll see that the new modifications are reflected in the "git-diff"
-output:
-
-------------------------------------------------
-$ echo 'again?' >>file.txt
-$ git diff
-index 513feba..ba3da7b 100644

-+again?
-------------------------------------------------
-
-With the right arguments, git diff can also show us the difference
-between the working directory and the last commit, or between the
-index and the last commit:
-
-------------------------------------------------
-$ git diff HEAD
-diff --git a/file.txt b/file.txt
-index a042389..ba3da7b 100644

---- a/file.txt

-@@ -1 +1,2 @@
- hello world!
-+hello world, again
-------------------------------------------------
-
-At any time, we can create a new commit using "git commit" (without
-the -a option), and verify that the state committed only includes the
-changes stored in the index file, not the additional change that is
-still only in our working tree:
-
-------------------------------------------------
-$ git commit -m "repeat"
-$ git diff HEAD
-diff --git a/file.txt b/file.txt

-------------------------------------------------
-
-So by default "git commit" uses the index to create the commit, not
-the working tree; the -a option to commit tells it to first update
-the index with all changes in the working tree.
-
-Finally, it's worth looking at the effect of "git add" on the index
-file:
-
-------------------------------------------------
-$ echo "goodbye, world" >closing.txt
-$ git add closing.txt
-------------------------------------------------
-
-The effect of the "git add" was to add one entry to the index file:
-
-------------------------------------------------
-$ git ls-files --stage
-100644 8b9743b20d4b15be3955fc8d5cd2b09cd2336138 0       closing.txt
-100644 513feba2e53ebbd2532419ded848ba19de88ba00 0       file.txt
-------------------------------------------------
-
-And, as you can see with cat-file, this new entry refers to the
-current contents of the file:
-
-------------------------------------------------
-$ git cat-file blob 8b9743b2
-goodbye, world
-------------------------------------------------
-
-The "status" command is a useful way to get a quick summary of the
-situation:
-
-------------------------------------------------
-$ git status
-# On branch master
-# Changes to be committed:
-#   (use "git reset HEAD <file>..." to unstage)
-#
-#       new file: closing.txt
-#
-# Changed but not updated:
-#   (use "git add <file>..." to update what will be committed)
-#
-#       modified: file.txt
-#
-------------------------------------------------
-
-Since the current state of closing.txt is cached in the index file,
-it is listed as "Changes to be committed".  Since file.txt has
-changes in the working directory that aren't reflected in the index,
-it is marked "changed but not updated".  At this point, running "git
-commit" would create a commit that added closing.txt (with its new
-contents), but that didn't modify file.txt.
-
-Also, note that a bare "git diff" shows the changes to file.txt, but
-not the addition of closing.txt, because the version of closing.txt
-in the index file is identical to the one in the working directory.
-
-In addition to being the staging area for new commits, the index file
-is also populated from the object database when checking out a
-branch, and is used to hold the trees involved in a merge operation.
-See the link:core-tutorial.html[core tutorial] and the relevant man
-pages for details.
-
-What next?
-----------
-
-At this point you should know everything necessary to read the man
-pages for any of the git commands; one good place to start would be
-with the commands mentioned in link:everyday.html[Everyday git].  You
-should be able to find any unknown jargon in the
-link:glossary.html[Glossary].

-A tutorial introduction to git
-==============================
-
-This tutorial explains how to import a new project into git, make
-changes to it, and share changes with other developers.
-
-First, note that you can get documentation for a command such as "git
-diff" with:
-
-------------------------------------------------
-$ man git-diff
-------------------------------------------------
-
-It is a good idea to introduce yourself to git with your name and
-public email address before doing any operation.  The easiest
-way to do so is:
-
-------------------------------------------------
-$ git config --global user.name "Your Name Comes Here"
-$ git config --global user.email you@yourdomain.example.com
-------------------------------------------------
-
-
-Importing a new project
------------------------
-
-Assume you have a tarball project.tar.gz with your initial work.  You
-can place it under git revision control as follows.
-
-------------------------------------------------
-$ tar xzf project.tar.gz
-$ cd project
-$ git init
-------------------------------------------------
-
-Git will reply
-
-------------------------------------------------
-Initialized empty Git repository in .git/
-------------------------------------------------
-
-You've now initialized the working directory--you may notice a new
-directory created, named ".git".  Tell git that you want it to track
-every file under the current directory (note the '.') with:
-
-------------------------------------------------
-$ git add .
-------------------------------------------------
-
-Finally,
-
-------------------------------------------------
-$ git commit
-------------------------------------------------
-
-will prompt you for a commit message, then record the current state
-of all the files to the repository.
-
-Making changes
---------------
-
-Try modifying some files, then run
-
-------------------------------------------------
-$ git diff
-------------------------------------------------
-
-to review your changes.  When you're done, tell git that you
-want the updated contents of these files in the commit and then
-make a commit, like this:
-
-------------------------------------------------
-$ git add file1 file2 file3
-$ git commit
-------------------------------------------------
-
-This will again prompt your for a message describing the change, and then
-record the new versions of the files you listed.
-
-Alternatively, instead of running `git add` beforehand, you can use
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-which will automatically notice modified (but not new) files.
-
-A note on commit messages: Though not required, it's a good idea to
-begin the commit message with a single short (less than 50 character)
-line summarizing the change, followed by a blank line and then a more
-thorough description.  Tools that turn commits into email, for
-example, use the first line on the Subject: line and the rest of the
-commit in the body.
-
-
-Git tracks content not files
-----------------------------
-
-With git you have to explicitly "add" all the changed _content_ you
-want to commit together. This can be done in a few different ways:
-
-1) By using 'git add <file_spec>...'
-
-This can be performed multiple times before a commit.  Note that this
-is not only for adding new files.  Even modified files must be
-added to the set of changes about to be committed.  The "git status"
-command gives you a summary of what is included so far for the
-next commit.  When done you should use the 'git commit' command to
-make it real.
-
-Note: don't forget to 'add' a file again if you modified it after the
-first 'add' and before 'commit'. Otherwise only the previous added
-state of that file will be committed. This is because git tracks
-content, so what you're really 'add'ing to the commit is the *content*
-of the file in the state it is in when you 'add' it.
-
-2) By using 'git commit -a' directly
-
-This is a quick way to automatically 'add' the content from all files
-that were modified since the previous commit, and perform the actual
-commit without having to separately 'add' them beforehand.  This will
-not add content from new files i.e. files that were never added before.
-Those files still have to be added explicitly before performing a
-commit.
-
-But here's a twist. If you do 'git commit <file1> <file2> ...' then only
-the  changes belonging to those explicitly specified files will be
-committed, entirely bypassing the current "added" changes. Those "added"
-changes will still remain available for a subsequent commit though.
-
-However, for normal usage you only have to remember 'git add' + 'git commit'
-and/or 'git commit -a'.
-
-
-Viewing the changelog
----------------------
-
-At any point you can view the history of your changes using
-
-------------------------------------------------
-$ git log
-------------------------------------------------
-
-If you also want to see complete diffs at each step, use
-
-------------------------------------------------
-$ git log -p
-------------------------------------------------
-
-Often the overview of the change is useful to get a feel of
-each step
-
-------------------------------------------------
-$ git log --stat --summary
-------------------------------------------------
-
-Managing branches
------------------
-
-A single git repository can maintain multiple branches of
-development.  To create a new branch named "experimental", use
-
-------------------------------------------------
-$ git branch experimental
-------------------------------------------------
-
-If you now run
-
-------------------------------------------------
-$ git branch
-------------------------------------------------
-
-you'll get a list of all existing branches:
-
-------------------------------------------------
-  experimental
-* master
-------------------------------------------------
-
-The "experimental" branch is the one you just created, and the
-"master" branch is a default branch that was created for you
-automatically.  The asterisk marks the branch you are currently on;
-type
-
-------------------------------------------------
-$ git checkout experimental
-------------------------------------------------
-
-to switch to the experimental branch.  Now edit a file, commit the
-change, and switch back to the master branch:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-$ git checkout master
-------------------------------------------------
-
-Check that the change you made is no longer visible, since it was
-made on the experimental branch and you're back on the master branch.
-
-You can make a different change on the master branch:
-
-------------------------------------------------
-(edit file)
-$ git commit -a
-------------------------------------------------
-
-at this point the two branches have diverged, with different changes
-made in each.  To merge the changes made in experimental into master, run
-
-------------------------------------------------
-$ git merge experimental
-------------------------------------------------
-
-If the changes don't conflict, you're done.  If there are conflicts,
-markers will be left in the problematic files showing the conflict;
-
-------------------------------------------------
-$ git diff
-------------------------------------------------
-
-will show this.  Once you've edited the files to resolve the
-conflicts,
-
-------------------------------------------------
-$ git commit -a
-------------------------------------------------
-
-will commit the result of the merge. Finally,
-
-------------------------------------------------
-$ gitk
-------------------------------------------------
-
-will show a nice graphical representation of the resulting history.
-
-At this point you could delete the experimental branch with
-
-------------------------------------------------
-$ git branch -d experimental
-------------------------------------------------
-
-This command ensures that the changes in the experimental branch are
-already in the current branch.
-
-If you develop on a branch crazy-idea, then regret it, you can always
-delete the branch with
-
--------------------------------------
-$ git branch -D crazy-idea
--------------------------------------
-
-Branches are cheap and easy, so this is a good way to try something
-out.
-
-Using git for collaboration
----------------------------
-
-Suppose that Alice has started a new project with a git repository in
-/home/alice/project, and that Bob, who has a home directory on the
-same machine, wants to contribute.
-
-Bob begins with:
-
-------------------------------------------------
-$ git clone /home/alice/project myrepo
-------------------------------------------------
-
-This creates a new directory "myrepo" containing a clone of Alice's
-repository.  The clone is on an equal footing with the original
-project, possessing its own copy of the original project's history.
-
-Bob then makes some changes and commits them:
-
-------------------------------------------------
-(edit files)
-$ git commit -a
-(repeat as necessary)
-------------------------------------------------
-
-When he's ready, he tells Alice to pull changes from the repository
-at /home/bob/myrepo.  She does this with:
-
-------------------------------------------------
-$ cd /home/alice/project
-$ git pull /home/bob/myrepo master
-------------------------------------------------
-
-This merges the changes from Bob's "master" branch into Alice's
-current branch.  If Alice has made her own changes in the meantime,
-then she may need to manually fix any conflicts.  (Note that the
-"master" argument in the above command is actually unnecessary, as it
-is the default.)
-
-The "pull" command thus performs two operations: it fetches changes
-from a remote branch, then merges them into the current branch.
-
-When you are working in a small closely knit group, it is not
-unusual to interact with the same repository over and over
-again.  By defining 'remote' repository shorthand, you can make
-it easier:
-
-------------------------------------------------
-$ git remote add bob /home/bob/myrepo
-------------------------------------------------
-
-With this, you can perform the first operation alone using the
-"git fetch" command without merging them with her own branch,
-using:
-
--------------------------------------
-$ git fetch bob
--------------------------------------
-
-Unlike the longhand form, when Alice fetches from Bob using a
-remote repository shorthand set up with `git remote`, what was
-fetched is stored in a remote tracking branch, in this case
-`bob/master`.  So after this:
-
--------------------------------------
-$ git log -p master..bob/master
--------------------------------------
-
-shows a list of all the changes that Bob made since he branched from
-Alice's master branch.
-
-After examining those changes, Alice
-could merge the changes into her master branch:
-
--------------------------------------
-$ git merge bob/master
--------------------------------------
-
-This `merge` can also be done by 'pulling from her own remote
-tracking branch', like this:
-
--------------------------------------
-$ git pull . remotes/bob/master
--------------------------------------
-
-Note that git pull always merges into the current branch,
-regardless of what else is given on the commandline.
-
-Later, Bob can update his repo with Alice's latest changes using
-
--------------------------------------
-$ git pull
--------------------------------------
-
-Note that he doesn't need to give the path to Alice's repository;
-when Bob cloned Alice's repository, git stored the location of her
-repository in the repository configuration, and that location is
-used for pulls:
-
--------------------------------------
-$ git config --get remote.origin.url
-/home/bob/myrepo
--------------------------------------
-
-(The complete configuration created by git-clone is visible using
-"git config -l", and the gitlink:git-config[1] man page
-explains the meaning of each option.)
-
-Git also keeps a pristine copy of Alice's master branch under the
-name "origin/master":
-
--------------------------------------
-$ git branch -r
-  origin/master
--------------------------------------
-
-If Bob later decides to work from a different host, he can still
-perform clones and pulls using the ssh protocol:
-
--------------------------------------
-$ git clone alice.org:/home/alice/project myrepo
--------------------------------------
-
-Alternatively, git has a native protocol, or can use rsync or http;
-see gitlink:git-pull[1] for details.
-
-Git can also be used in a CVS-like mode, with a central repository
-that various users push changes to; see gitlink:git-push[1] and
-link:cvs-migration.html[git for CVS users].
-
-Exploring history
------------------
-
-Git history is represented as a series of interrelated commits.  We
-have already seen that the git log command can list those commits.
-Note that first line of each git log entry also gives a name for the
-commit:
-
--------------------------------------
-$ git log
-commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
-Author: Junio C Hamano <junkio@cox.net>
-Date:   Tue May 16 17:18:22 2006 -0700
-
-    merge-base: Clarify the comments on post processing.
--------------------------------------
-
-We can give this name to git show to see the details about this
-commit.
-
--------------------------------------
-$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
--------------------------------------
-
-But there are other ways to refer to commits.  You can use any initial
-part of the name that is long enough to uniquely identify the commit:
-
--------------------------------------
-$ git show c82a22c39c	# the first few characters of the name are
-			# usually enough
-$ git show HEAD		# the tip of the current branch
-$ git show experimental	# the tip of the "experimental" branch
--------------------------------------
-
-Every commit usually has one "parent" commit
-which points to the previous state of the project:
-
--------------------------------------
-$ git show HEAD^  # to see the parent of HEAD
-$ git show HEAD^^ # to see the grandparent of HEAD
-$ git show HEAD~4 # to see the great-great grandparent of HEAD
--------------------------------------
-
-Note that merge commits may have more than one parent:
-
--------------------------------------
-$ git show HEAD^1 # show the first parent of HEAD (same as HEAD^)
-$ git show HEAD^2 # show the second parent of HEAD
--------------------------------------
-
-You can also give commits names of your own; after running
-
--------------------------------------
-$ git-tag v2.5 1b2e1d63ff
--------------------------------------
-
-you can refer to 1b2e1d63ff by the name "v2.5".  If you intend to
-share this name with other people (for example, to identify a release
-version), you should create a "tag" object, and perhaps sign it; see
-gitlink:git-tag[1] for details.
-
-Any git command that needs to know a commit can take any of these
-names.  For example:
-
--------------------------------------
-$ git diff v2.5 HEAD	 # compare the current HEAD to v2.5
-$ git branch stable v2.5 # start a new branch named "stable" based
-			 # at v2.5
-$ git reset --hard HEAD^ # reset your current branch and working
-			 # directory to its state at HEAD^
--------------------------------------
-
-Be careful with that last command: in addition to losing any changes
-in the working directory, it will also remove all later commits from
-this branch.  If this branch is the only branch containing those
-commits, they will be lost.  Also, don't use "git reset" on a
-publicly-visible branch that other developers pull from, as it will
-force needless merges on other developers to clean up the history.
-If you need to undo changes that you have pushed, use gitlink:git-revert[1]
-instead.
-
-The git grep command can search for strings in any version of your
-project, so
-
--------------------------------------
-$ git grep "hello" v2.5
--------------------------------------
-
-searches for all occurrences of "hello" in v2.5.
-
-If you leave out the commit name, git grep will search any of the
-files it manages in your current directory.  So
-
--------------------------------------
-$ git grep "hello"
--------------------------------------
-
-is a quick way to search just the files that are tracked by git.
-
-Many git commands also take sets of commits, which can be specified
-in a number of ways.  Here are some examples with git log:
-
--------------------------------------
-$ git log v2.5..v2.6            # commits between v2.5 and v2.6
-$ git log v2.5..                # commits since v2.5
-$ git log --since="2 weeks ago" # commits from the last 2 weeks
-$ git log v2.5.. Makefile       # commits since v2.5 which modify
-				# Makefile
--------------------------------------
-
-You can also give git log a "range" of commits where the first is not
-necessarily an ancestor of the second; for example, if the tips of
-the branches "stable-release" and "master" diverged from a common
-commit some time ago, then
-
--------------------------------------
-$ git log stable..experimental
--------------------------------------
-
-will list commits made in the experimental branch but not in the
-stable branch, while
-
--------------------------------------
-$ git log experimental..stable
--------------------------------------
-
-will show the list of commits made on the stable branch but not
-the experimental branch.
-
-The "git log" command has a weakness: it must present commits in a
-list.  When the history has lines of development that diverged and
-then merged back together, the order in which "git log" presents
-those commits is meaningless.
-
-Most projects with multiple contributors (such as the linux kernel,
-or git itself) have frequent merges, and gitk does a better job of
-visualizing their history.  For example,
-
--------------------------------------
-$ gitk --since="2 weeks ago" drivers/
--------------------------------------
-
-allows you to browse any commits from the last 2 weeks of commits
-that modified files under the "drivers" directory.  (Note: you can
-adjust gitk's fonts by holding down the control key while pressing
-"-" or "+".)
-
-Finally, most commands that take filenames will optionally allow you
-to precede any filename by a commit, to specify a particular version
-of the file:
-
--------------------------------------
-$ git diff v2.5:Makefile HEAD:Makefile.in
--------------------------------------
-
-You can also use "git show" to see any such file:
-
--------------------------------------
-$ git show v2.5:Makefile
--------------------------------------
-
-Next Steps
-----------
-
-This tutorial should be enough to perform basic distributed revision
-control for your projects.  However, to fully understand the depth
-and power of git you need to understand two simple ideas on which it
-is based:
-
-  * The object database is the rather elegant system used to
-    store the history of your project--files, directories, and
-    commits.
-
-  * The index file is a cache of the state of a directory tree,
-    used to create commits, check out working directories, and
-    hold the various trees involved in a merge.
-
-link:tutorial-2.html[Part two of this tutorial] explains the object
-database, the index file, and a few other odds and ends that you'll
-need to make the most of git.
-
-If you don't want to consider with that right away, a few other
-digressions that may be interesting at this point are:
-
-  * gitlink:git-format-patch[1], gitlink:git-am[1]: These convert
-    series of git commits into emailed patches, and vice versa,
-    useful for projects such as the linux kernel which rely heavily
-    on emailed patches.
-
-  * gitlink:git-bisect[1]: When there is a regression in your
-    project, one way to track down the bug is by searching through
-    the history to find the exact commit that's to blame.  Git bisect
-    can help you perform a binary search for that commit.  It is
-    smart enough to perform a close-to-optimal search even in the
-    case of complex non-linear history with lots of merged branches.

+REMOTES[[REMOTES]]
+------------------
+
+The name of one of the following can be used instead
+of a URL as `<repository>` argument:
+
+* a remote in the Git configuration file: `$GIT_DIR/config`,
+* a file in the `$GIT_DIR/remotes` directory, or
+* a file in the `$GIT_DIR/branches` directory.
+
+All of these also allow you to omit the refspec from the command line
+because they each contain a refspec which git will use by default.
+
+Named remote in configuration file
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can choose to provide the name of a remote which you had previously
+configured using linkgit:git-remote[1], linkgit:git-config[1]
+or even by a manual edit to the `$GIT_DIR/config` file.  The URL of
+this remote will be used to access the repository.  The refspec
+of this remote will be used by default when you do
+not provide a refspec on the command line.  The entry in the
+config file would appear like this:
+
+------------
+	[remote "<name>"]
+		url = <url>
+		pushurl = <pushurl>
+		push = <refspec>
+		fetch = <refspec>
+------------
+
+The `<pushurl>` is used for pushes only. It is optional and defaults
+to `<url>`.
+
+Named file in `$GIT_DIR/remotes`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can choose to provide the name of a
+file in `$GIT_DIR/remotes`.  The URL
+in this file will be used to access the repository.  The refspec
+in this file will be used as default when you do not
+provide a refspec on the command line.  This file should have the
+following format:
+
+------------
+	URL: one of the above URL format
+	Push: <refspec>
+	Pull: <refspec>
+
+------------
+
+`Push:` lines are used by 'git push' and
+`Pull:` lines are used by 'git pull' and 'git fetch'.
+Multiple `Push:` and `Pull:` lines may
+be specified for additional branch mappings.
+
+Named file in `$GIT_DIR/branches`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can choose to provide the name of a
+file in `$GIT_DIR/branches`.
+The URL in this file will be used to access the repository.
+This file should have the following format:
+
+
+------------
+	<url>#<head>
+------------
+
+`<url>` is required; `#<head>` is optional.
+
+Depending on the operation, git will use one of the following
+refspecs, if you don't provide one on the command line.
+`<branch>` is the name of this file in `$GIT_DIR/branches` and
+`<head>` defaults to `master`.
+
+git fetch uses:
+
+------------
+	refs/heads/<head>:refs/heads/<branch>
+------------
+
+git push uses:
+
+------------
+	HEAD:refs/heads/<head>
+------------

 GIT URLS[[URLS]]
 ----------------
 
-One of the following notations can be used
-to name the remote repository:
+In general, URLs contain information about the transport protocol, the
+address of the remote server, and the path to the repository.
+Depending on the transport protocol, some of this information may be
+absent.
 
-===============================================================
+Git supports ssh, git, http, and https protocols (in addition, ftp,
+and ftps can be used for fetching and rsync can be used for fetching
+and pushing, but these are inefficient and deprecated; do not use
+them).
+
+The native transport (i.e. git:// URL) does no authentication and
+should be used with caution on unsecured networks.
+
+The following syntaxes may be used with them:
+
+- ssh://{startsb}user@{endsb}host.xz{startsb}:port{endsb}/path/to/repo.git/
+- git://host.xz{startsb}:port{endsb}/path/to/repo.git/
+- http{startsb}s{endsb}://host.xz{startsb}:port{endsb}/path/to/repo.git/
+- ftp{startsb}s{endsb}://host.xz{startsb}:port{endsb}/path/to/repo.git/
 - rsync://host.xz/path/to/repo.git/
-- http://host.xz/path/to/repo.git/
-- https://host.xz/path/to/repo.git/
-- git://host.xz/path/to/repo.git/
-- git://host.xz/~user/path/to/repo.git/
-- ssh://{startsb}user@{endsb}host.xz/path/to/repo.git/
-- ssh://{startsb}user@{endsb}host.xz/~user/path/to/repo.git/
-- ssh://{startsb}user@{endsb}host.xz/~/path/to/repo.git
-===============================================================
-
-SSH is the default transport protocol.  You can optionally specify
-which user to log-in as, and an alternate, scp-like syntax is also
-supported.  Both syntaxes support username expansion,
-as does the native git protocol. The following three are
-identical to the last three above, respectively:
-
-===============================================================
-- {startsb}user@{endsb}host.xz:/path/to/repo.git/
-- {startsb}user@{endsb}host.xz:~user/path/to/repo.git/
-- {startsb}user@{endsb}host.xz:path/to/repo.git
-===============================================================
-
-To sync with a local directory, use:
-
-===============================================================
+
+An alternative scp-like syntax may also be used with the ssh protocol:
+
+- {startsb}user@{endsb}host.xz:path/to/repo.git/
+
+This syntax is only recognized if there are no slashes before the
+first colon. This helps differentiate a local path that contains a
+colon. For example the local path `foo:bar` could be specified as an
+absolute path or `./foo:bar` to avoid being misinterpreted as an ssh
+url.
+
+The ssh and git protocols additionally support ~username expansion:
+
+- ssh://{startsb}user@{endsb}host.xz{startsb}:port{endsb}/~{startsb}user{endsb}/path/to/repo.git/
+- git://host.xz{startsb}:port{endsb}/~{startsb}user{endsb}/path/to/repo.git/
+- {startsb}user@{endsb}host.xz:/~{startsb}user{endsb}/path/to/repo.git/
+
+For local repositories, also supported by Git natively, the following
+syntaxes may be used:
+
 - /path/to/repo.git/
-===============================================================
+- \file:///path/to/repo.git/
 
-REMOTES
--------
+ifndef::git-clone[]
+These two syntaxes are mostly equivalent, except when cloning, when
+the former implies --local option. See linkgit:git-clone[1] for
+details.
+endif::git-clone[]
 
-In addition to the above, as a short-hand, the name of a
-file in `$GIT_DIR/remotes` directory can be given; the
-named file should be in the following format:
+ifdef::git-clone[]
+These two syntaxes are mostly equivalent, except the former implies
+--local option.
+endif::git-clone[]
 
-------------
-	URL: one of the above URL format
-	Push: <refspec>
-	Pull: <refspec>
+When Git doesn't know how to handle a certain transport protocol, it
+attempts to use the 'remote-<transport>' remote helper, if one
+exists. To explicitly request a remote helper, the following syntax
+may be used:
 
-------------
+- <transport>::<address>
 
-Then such a short-hand is specified in place of
-<repository> without <refspec> parameters on the command
-line, <refspec> specified on `Push:` lines or `Pull:`
-lines are used for `git-push` and `git-fetch`/`git-pull`,
-respectively.  Multiple `Push:` and `Pull:` lines may
-be specified for additional branch mappings.
+where <address> may be a path, a server and path, or an arbitrary
+URL-like string recognized by the specific remote helper being
+invoked. See linkgit:gitremote-helpers[1] for details.
 
-Or, equivalently, in the `$GIT_DIR/config` (note the use
-of `fetch` instead of `Pull:`):
+If there are a large number of similarly-named remote repositories and
+you want to use a different format for them (such that the URLs you
+use will be rewritten into URLs that work), you can create a
+configuration section of the form:
 
 ------------
-	[remote "<remote>"]
-		url = <url>
-		push = <refspec>
-		fetch = <refspec>
-
+	[url "<actual url base>"]
+		insteadOf = <other url base>
 ------------
 
-The name of a file in `$GIT_DIR/branches` directory can be
-specified as an older notation short-hand; the named
-file should contain a single line, a URL in one of the
-above formats, optionally followed by a hash `#` and the
-name of remote head (URL fragment notation).
-`$GIT_DIR/branches/<remote>` file that stores a <url>
-without the fragment is equivalent to have this in the
-corresponding file in the `$GIT_DIR/remotes/` directory.
+For example, with this:
 
 ------------
-	URL: <url>
-	Pull: refs/heads/master:<remote>
+	[url "git://git.host.xz/"]
+		insteadOf = host.xz:/path/to/
+		insteadOf = work:
+------------
+
+a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be
+rewritten in any context that takes a URL to be "git://git.host.xz/repo.git".
+
+If you want to rewrite URLs for push only, you can create a
+configuration section of the form:
 
 ------------
+	[url "<actual url base>"]
+		pushInsteadOf = <other url base>
+------------
 
-while having `<url>#<head>` is equivalent to
+For example, with this:
 
 ------------
-	URL: <url>
-	Pull: refs/heads/<head>:<remote>
+	[url "ssh://example.org/"]
+		pushInsteadOf = git://example.org/
 ------------
+
+a URL like "git://example.org/path/to/repo.git" will be rewritten to
+"ssh://example.org/path/to/repo.git" for pushes, but pulls will still
+use the original URL.

+This manual is designed to be readable by someone with basic UNIX
+command-line skills, but no previous knowledge of Git.
 
-Chapters 2 and 3 explain how to fetch and study a project using
-git--the tools you'd need to build and test a particular version of a
-software project, to search for regressions, and so on.
+<<repositories-and-branches>> and <<exploring-git-history>> explain how
+to fetch and study a project using git--read these chapters to learn how
+to build and test a particular version of a software project, search for
+regressions, and so on.
 
-Chapter 4 explains how to do development with git, and chapter 5 how
-to share that development with others.
+People needing to do actual development will also want to read
+<<Developing-With-git>> and <<sharing-development>>.
 
 Further chapters cover more specialized topics.
 
 Comprehensive reference documentation is available through the man

 ------------------------------------------------
 
-Git Quick Start
-===============
-
-This is a quick summary of the major commands; the following chapters
-will explain how these work in more detail.
-
-Creating a new repository
--------------------------
-
-From a tarball:
-
------------------------------------------------
-$ tar xzf project.tar.gz
-$ cd project
-$ git init
-Initialized empty Git repository in .git/
-$ git add .
-$ git commit
------------------------------------------------
-
-From a remote repository:
-
------------------------------------------------
-$ git clone git://example.com/pub/project.git
-$ cd project
------------------------------------------------
-
-Managing branches
------------------
-
------------------------------------------------
-$ git branch	     # list all branches in this repo
-$ git checkout test  # switch working directory to branch "test"
-$ git branch new     # create branch "new" starting at current HEAD
-$ git branch -d new  # delete branch "new"
------------------------------------------------
-
-Instead of basing new branch on current HEAD (the default), use:
-
------------------------------------------------
-$ git branch new test    # branch named "test"
-$ git branch new v2.6.15 # tag named v2.6.15
-$ git branch new HEAD^   # commit before the most recent
-$ git branch new HEAD^^  # commit before that
-$ git branch new test~10 # ten commits before tip of branch "test"
------------------------------------------------
-
-Create and switch to a new branch at the same time:
-
------------------------------------------------
-$ git checkout -b new v2.6.15
------------------------------------------------
-
-Update and examine branches from the repository you cloned from:
-
------------------------------------------------
-$ git fetch		# update
-$ git branch -r		# list
-  origin/master
-  origin/next
-  ...
-$ git branch checkout -b masterwork origin/master
------------------------------------------------
-
-Fetch a branch from a different repository, and give it a new
-name in your repository:
-
------------------------------------------------
-$ git fetch git://example.com/project.git theirbranch:mybranch
-$ git fetch git://example.com/project.git v2.6.15:mybranch
------------------------------------------------
-
-Keep a list of repositories you work with regularly:
-
------------------------------------------------
-$ git remote add example git://example.com/project.git
-$ git remote			# list remote repositories
-example
-origin
-$ git remote show example	# get details
-* remote example
-  URL: git://example.com/project.git
-  Tracked remote branches
-    master next ...
-$ git fetch example		# update branches from example
-$ git branch -r			# list all remote branches
------------------------------------------------
-
-
-Exploring history
------------------
-
------------------------------------------------
-$ gitk			    # visualize and browse history
-$ git log		    # list all commits
-$ git log src/		    # ...modifying src/
-$ git log v2.6.15..v2.6.16  # ...in v2.6.16, not in v2.6.15
-$ git log master..test	    # ...in branch test, not in branch master
-$ git log test..master	    # ...in branch master, but not in test
-$ git log test...master	    # ...in one branch, not in both
-$ git log -S'foo()'	    # ...where difference contain "foo()"
-$ git log --since="2 weeks ago"
-$ git log -p		    # show patches as well
-$ git show		    # most recent commit
-$ git diff v2.6.15..v2.6.16 # diff between two tagged versions
-$ git diff v2.6.15..HEAD    # diff with current head
-$ git grep "foo()"	    # search working directory for "foo()"
-$ git grep v2.6.15 "foo()"  # search old tree for "foo()"
-$ git show v2.6.15:a.txt    # look at old version of a.txt
------------------------------------------------
-
-Search for regressions:
-
------------------------------------------------
-$ git bisect start
-$ git bisect bad		# current version is bad
-$ git bisect good v2.6.13-rc2	# last known good revision
-Bisecting: 675 revisions left to test after this
-				# test here, then:
-$ git bisect good		# if this revision is good, or
-$ git bisect bad		# if this revision is bad.
-				# repeat until done.
------------------------------------------------
-
-Making changes
---------------
-
-Make sure git knows who to blame:
+or:
 
 ------------------------------------------------
-$ cat >~/.gitconfig <<\EOF
-[user]
-name = Your Name Comes Here
-email = you@yourdomain.example.com
-EOF
+$ git help clone
 ------------------------------------------------
 
-Select file contents to include in the next commit, then make the
-commit:
-
------------------------------------------------
-$ git add a.txt    # updated file
-$ git add b.txt    # new file
-$ git rm c.txt     # old file
-$ git commit
------------------------------------------------
+With the latter, you can use the manual viewer of your choice; see
+linkgit:git-help[1] for more information.
 
-Or, prepare and create the commit in one step:
+See also <<git-quick-start>> for a brief overview of Git commands,
+without any explanation.
 
------------------------------------------------
-$ git commit d.txt # use latest content only of d.txt
-$ git commit -a	   # use latest content of all tracked files
------------------------------------------------
+Finally, see <<todo>> for ways that you can help make this manual more
+complete.
 
-Merging
--------
-
------------------------------------------------

 Manipulating branches

 Creating, deleting, and modifying branches is quick and easy; here's
 a summary of the commands:
 
-git branch::
-	list all branches
-git branch <branch>::
-	create a new branch named <branch>, referencing the same
-	point in history as the current branch
-git branch <branch> <start-point>::
-	create a new branch named <branch>, referencing
-	<start-point>, which may be specified any way you like,
-	including using a branch name or a tag name
-git branch -d <branch>::
-	delete the branch <branch>; if the branch you are deleting
-	points to a commit which is not reachable from this branch,
+`git branch`::
+	list all branches.
+`git branch <branch>`::
+	create a new branch named `<branch>`, referencing the same
+	point in history as the current branch.
+`git branch <branch> <start-point>`::
+	create a new branch named `<branch>`, referencing
+	`<start-point>`, which may be specified any way you like,
+	including using a branch name or a tag name.
+`git branch -d <branch>`::
+	delete the branch `<branch>`; if the branch is not fully
+	merged in its upstream branch or contained in the current branch,
 	this command will fail with a warning.
-git branch -D <branch>::
-	even if the branch points to a commit not reachable
-	from the current branch, you may know that that commit
-	is still reachable from some other branch or tag.  In that
-	case it is safe to use this command to force git to delete
-	the branch.
-git checkout <branch>::
-	make the current branch <branch>, updating the working
-	directory to reflect the version referenced by <branch>
-git checkout -b <new> <start-point>::
-	create a new branch <new> referencing <start-point>, and

+The special symbol "HEAD" can always be used to refer to the current

+to remember which branch is current:

+ref: refs/heads/master
+------------------------------------------------
 
+[[detached-head]]
+Examining an old version without creating a new branch
+------------------------------------------------------
+
+The `git checkout` command normally expects a branch head, but will also
+accept an arbitrary commit; for example, you can check out the commit
+referenced by a tag:
+
+------------------------------------------------
+$ git checkout v2.6.17
+Note: checking out 'v2.6.17'.
+
+You are in 'detached HEAD' state. You can look around, make experimental
+changes and commit them, and you can discard any commits you make in this
+state without impacting any branches by performing another checkout.
+
+If you want to create a new branch to retain commits you create, you may
+do so (now or later) by using -b with the checkout command again. Example:
+
+  git checkout -b new_branch_name
+
+HEAD is now at 427abfa... Linux v2.6.17
+------------------------------------------------
+
+The HEAD then refers to the SHA-1 of the commit instead of to a branch,
+and git branch shows that you are no longer on a branch:

+$ git branch
+* (detached from v2.6.17)

+
+In this case we say that the HEAD is "detached".

+This is an easy way to check out a particular version without having to
+make up a name for the new branch.   You can still create a new branch

-how to merge
+[[ignoring-files]]
+Ignoring files
+--------------
+
+A project will often generate files that you do 'not' want to track with Git.
+This typically includes files generated by a build process or temporary
+backup files made by your editor. Of course, 'not' tracking files with Git
+is just a matter of 'not' calling `git add` on them. But it quickly becomes
+annoying to have these untracked files lying around; e.g. they make
+`git add .` practically useless, and they keep showing up in the output of
+`git status`.
+
+You can tell Git to ignore certain files by creating a file called
+`.gitignore` in the top level of your working directory, with contents
+such as:
+
+-------------------------------------------------
+# Lines starting with '#' are considered comments.
+# Ignore any file named foo.txt.
+foo.txt
+# Ignore (generated) html files,
+*.html
+# except foo.html which is maintained by hand.
+!foo.html
+# Ignore objects and archives.
+*.[oa]
+-------------------------------------------------
+
+See linkgit:gitignore[5] for a detailed explanation of the syntax.  You can
+also place .gitignore files in other directories in your working tree, and they
+will apply to those directories and their subdirectories.  The `.gitignore`
+files can be added to your repository like any other files (just run `git add
+.gitignore` and `git commit`, as usual), which is convenient when the exclude
+patterns (such as patterns matching build output files) would also make sense
+for other users who clone your repository.
+
+If you wish the exclude patterns to affect only certain repositories
+(instead of every repository for a given project), you may instead put
+them in a file in your repository named `.git/info/exclude`, or in any
+file specified by the `core.excludesFile` configuration variable.
+Some Git commands can also take exclude patterns directly on the
+command line.  See linkgit:gitignore[5] for the details.

+merges the development in the branch `branchname` into the current
+branch.
+
+A merge is made by combining the changes made in `branchname` and the
+changes made up to the latest commit in your current branch since
+their histories forked. The work tree is overwritten by the result of
+the merge when this combining is done cleanly, or overwritten by a
+half-merged results when this combining results in conflicts.
+Therefore, if you have uncommitted changes touching the same files as
+the ones impacted by the merge, Git will refuse to proceed. Most of
+the time, you will want to commit your changes before you can merge,
+and if you don't, then linkgit:git-stash[1] can take these changes
+away while you're doing the merge, and reapply them afterwards.
+
+If the changes are independent enough, Git will automatically complete
+the merge and commit the result (or reuse an existing commit in case
+of <<fast-forwards,fast-forward>>, see below). On the other hand,
+if there are conflicts--for example, if the same file is
 modified in two different ways in the remote branch and the local
 branch--then you are warned; the output may look something like this:

+[[forcing-push]]
+What to do when a push fails
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a push would not result in a <<fast-forwards,fast-forward>> of the
+remote branch, then it will fail with an error like:
+
+-------------------------------------------------
+error: remote 'refs/heads/master' is not an ancestor of
+ local  'refs/heads/master'.
+ Maybe you are not up-to-date and need to pull first?
+error: failed to push to 'ssh://yourserver.com/~you/proj.git'
+-------------------------------------------------
 
+This can happen, for example, if you:
+
+	- use `git reset --hard` to remove already-published commits, or
+	- use `git commit --amend` to replace already-published commits
+	  (as in <<fixing-a-mistake-by-rewriting-history>>), or
+	- use `git rebase` to rebase any already-published commits (as
+	  in <<using-git-rebase>>).
+
+You may force `git push` to perform the update anyway by preceding the
+branch name with a plus sign:
+
+-------------------------------------------------
+$ git push ssh://yourserver.com/~you/proj.git +master
+-------------------------------------------------
+
+Note the addition of the `+` sign.  Alternatively, you can use the
+`-f` flag to force the remote update, as in:
+
+-------------------------------------------------
+$ git push -f ssh://yourserver.com/~you/proj.git master
+-------------------------------------------------
+
+Normally whenever a branch head in a public repository is modified, it
+is modified to point to a descendant of the commit that it pointed to
+before.  By forcing a push in this situation, you break that convention.
+(See <<problems-With-rewriting-history>>.)
+
+Nevertheless, this is a common practice for people that need a simple
+way to publish a work-in-progress patch series, and it is an acceptable
+compromise as long as you warn other developers that this is how you
+intend to manage the branch.
+
+It's also possible for a push to fail in this way when other people have
+the right to push to the same repository.  In that case, the correct
+solution is to retry the push after first updating your work: either by a
+pull, or by a fetch followed by a rebase; see the
+<<setting-up-a-shared-repository,next section>> and
+linkgit:gitcvs-migration[7] for more.
+
+[[setting-up-a-shared-repository]]
 Setting up a shared repository
-------------------------------
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Another way to collaborate is by using a model similar to that
 commonly used in CVS, where several developers with special rights
 all push to and pull from a single shared repository.  See
-link:cvs-migration.txt[git for CVS users] for instructions on how to
+linkgit:gitcvs-migration[7] for instructions on how to
 set this up.
 
-Allow web browsing of a repository
-----------------------------------
+However, while there is nothing wrong with Git's support for shared
+repositories, this mode of operation is not generally recommended,
+simply because the mode of collaboration that Git supports--by
+exchanging patches and pulling from public repositories--has so many
+advantages over the central shared repository:
+
+	- Git's ability to quickly import and merge patches allows a
+	  single maintainer to process incoming changes even at very
+	  high rates.  And when that becomes too much, `git pull` provides
+	  an easy way for that maintainer to delegate this job to other
+	  maintainers while still allowing optional review of incoming
+	  changes.
+	- Since every developer's repository has the same complete copy
+	  of the project history, no repository is special, and it is
+	  trivial for another developer to take over maintenance of a
+	  project, either by mutual agreement, or because a maintainer
+	  becomes unresponsive or difficult to work with.
+	- The lack of a central group of "committers" means there is
+	  less need for formal decisions about who is "in" and who is
+	  "out".

-TODO: topic branches, typical roles as in everyday.txt, ?
+[[maintaining-topic-branches]]
+Maintaining topic branches for a Linux subsystem maintainer
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This describes how Tony Luck uses Git in his role as maintainer of the
+IA64 architecture for the Linux kernel.
+
+He uses two public branches:
+
+ - A "test" tree into which patches are initially placed so that they
+   can get some exposure when integrated with other ongoing development.
+   This tree is available to Andrew for pulling into -mm whenever he
+   wants.
+
+ - A "release" tree into which tested patches are moved for final sanity
+   checking, and as a vehicle to send them upstream to Linus (by sending
+   him a "please pull" request.)
+
+He also uses a set of temporary branches ("topic branches"), each
+containing a logical grouping of patches.
+
+To set this up, first create your work tree by cloning Linus's public
+tree:
+
+-------------------------------------------------
+$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git work
+$ cd work
+-------------------------------------------------
+
+Linus's tree will be stored in the remote-tracking branch named origin/master,
+and can be updated using linkgit:git-fetch[1]; you can track other
+public trees using linkgit:git-remote[1] to set up a "remote" and
+linkgit:git-fetch[1] to keep them up-to-date; see
+<<repositories-and-branches>>.
+
+Now create the branches in which you are going to work; these start out
+at the current tip of origin/master branch, and should be set up (using
+the `--track` option to linkgit:git-branch[1]) to merge changes in from
+Linus by default.
+
+-------------------------------------------------
+$ git branch --track test origin/master
+$ git branch --track release origin/master
+-------------------------------------------------
+
+These can be easily kept up to date using linkgit:git-pull[1].
+
+-------------------------------------------------
+$ git checkout test && git pull
+$ git checkout release && git pull
+-------------------------------------------------
+
+Important note!  If you have any local changes in these branches, then
+this merge will create a commit object in the history (with no local
+changes Git will simply do a "fast-forward" merge).  Many people dislike
+the "noise" that this creates in the Linux history, so you should avoid
+doing this capriciously in the `release` branch, as these noisy commits
+will become part of the permanent history when you ask Linus to pull
+from the release branch.
+
+A few configuration variables (see linkgit:git-config[1]) can
+make it easy to push both branches to your public tree.  (See
+<<setting-up-a-public-repository>>.)
+
+-------------------------------------------------
+$ cat >> .git/config <<EOF
+[remote "mytree"]
+	url =  master.kernel.org:/pub/scm/linux/kernel/git/aegl/linux.git
+	push = release
+	push = test
+EOF
+-------------------------------------------------
+
+Then you can push both the test and release trees using
+linkgit:git-push[1]:
+
+-------------------------------------------------
+$ git push mytree
+-------------------------------------------------
+
+or push just one of the test and release branches using:
+
+-------------------------------------------------
+$ git push mytree test
+-------------------------------------------------
+
+or
+
+-------------------------------------------------
+$ git push mytree release
+-------------------------------------------------
+
+Now to apply some patches from the community.  Think of a short
+snappy name for a branch to hold this patch (or related group of
+patches), and create a new branch from a recent stable tag of
+Linus's branch. Picking a stable base for your branch will:
+1) help you: by avoiding inclusion of unrelated and perhaps lightly
+tested changes
+2) help future bug hunters that use `git bisect` to find problems
+
+-------------------------------------------------
+$ git checkout -b speed-up-spinlocks v2.6.35
+-------------------------------------------------
+
+Now you apply the patch(es), run some tests, and commit the change(s).  If
+the patch is a multi-part series, then you should apply each as a separate
+commit to this branch.
+
+-------------------------------------------------
+$ ... patch ... test  ... commit [ ... patch ... test ... commit ]*
+-------------------------------------------------
+
+When you are happy with the state of this change, you can merge it into the
+"test" branch in preparation to make it public:
+
+-------------------------------------------------
+$ git checkout test && git merge speed-up-spinlocks
+-------------------------------------------------
+
+It is unlikely that you would have any conflicts here ... but you might if you
+spent a while on this step and had also pulled new versions from upstream.
+
+Sometime later when enough time has passed and testing done, you can pull the
+same branch into the `release` tree ready to go upstream.  This is where you
+see the value of keeping each patch (or patch series) in its own branch.  It
+means that the patches can be moved into the `release` tree in any order.
+
+-------------------------------------------------
+$ git checkout release && git merge speed-up-spinlocks
+-------------------------------------------------
+
+After a while, you will have a number of branches, and despite the
+well chosen names you picked for each of them, you may forget what
+they are for, or what status they are in.  To get a reminder of what
+changes are in a specific branch, use:
+
+-------------------------------------------------
+$ git log linux..branchname | git shortlog
+-------------------------------------------------
+
+To see whether it has already been merged into the test or release branches,
+use:
+
+-------------------------------------------------
+$ git log test..branchname
+-------------------------------------------------
+
+or
+
+-------------------------------------------------
+$ git log release..branchname
+-------------------------------------------------
+
+(If this branch has not yet been merged, you will see some log entries.
+If it has been merged, then there will be no output.)
+
+Once a patch completes the great cycle (moving from test to release,
+then pulled by Linus, and finally coming back into your local
+`origin/master` branch), the branch for this change is no longer needed.
+You detect this when the output from:
+
+-------------------------------------------------
+$ git log origin..branchname
+-------------------------------------------------
+
+is empty.  At this point the branch can be deleted:
+
+-------------------------------------------------
+$ git branch -d branchname
+-------------------------------------------------
+
+Some changes are so trivial that it is not necessary to create a separate
+branch and then merge into each of the test and release branches.  For
+these changes, just apply directly to the `release` branch, and then
+merge that into the `test` branch.
+
+After pushing your work to `mytree`, you can use
+linkgit:git-request-pull[1] to prepare a "please pull" request message
+to send to Linus:
+
+-------------------------------------------------
+$ git push mytree
+$ git request-pull origin mytree release
+-------------------------------------------------
+
+Here are some of the scripts that simplify all this even further.

-$ git checkout -b mywork-new origin

+[[bisect-merges]]
+Why bisecting merge commits can be harder than bisecting linear history
+-----------------------------------------------------------------------
+
+The linkgit:git-bisect[1] command correctly handles history that
+includes merge commits.  However, when the commit that it finds is a
+merge commit, the user may need to work harder than usual to figure out
+why that commit introduced a problem.
+
+Imagine this history:
+
+................................................
+      ---Z---o---X---...---o---A---C---D
+          \                       /
+           o---o---Y---...---o---B
+................................................
+
+Suppose that on the upper line of development, the meaning of one
+of the functions that exists at Z is changed at commit X.  The
+commits from Z leading to A change both the function's
+implementation and all calling sites that exist at Z, as well
+as new calling sites they add, to be consistent.  There is no
+bug at A.
+
+Suppose that in the meantime on the lower line of development somebody
+adds a new calling site for that function at commit Y.  The
+commits from Z leading to B all assume the old semantics of that
+function and the callers and the callee are consistent with each
+other.  There is no bug at B, either.
+
+Suppose further that the two development lines merge cleanly at C,
+so no conflict resolution is required.
+
+Nevertheless, the code at C is broken, because the callers added
+on the lower line of development have not been converted to the new
+semantics introduced on the upper line of development.  So if all
+you know is that D is bad, that Z is good, and that
+linkgit:git-bisect[1] identifies C as the culprit, how will you
+figure out that the problem is due to this change in semantics?
+
+When the result of a `git bisect` is a non-merge commit, you should
+normally be able to discover the problem by examining just that commit.
+Developers can make this easy by breaking their changes into small
+self-contained commits.  That won't help in the case above, however,
+because the problem isn't obvious from examination of any single
+commit; instead, a global view of the development is required.  To
+make matters worse, the change in semantics in the problematic
+function may be just one small part of the changes in the upper
+line of development.
+
+On the other hand, if instead of merging at C you had rebased the
+history between Z to B on top of A, you would have gotten this
+linear history:
+
+................................................................
+    ---Z---o---X--...---o---A---o---o---Y*--...---o---B*--D*
+................................................................
+
+Bisecting between Z and D* would hit a single culprit commit Y*,
+and understanding why Y* was broken would probably be easier.
+
+Partly for this reason, many experienced Git users, even when
+working on an otherwise merge-heavy project, keep the history
+linear by rebasing against the latest upstream version before
+publishing.

+The Object Database
+-------------------
 
-[[git-internals]]
-Git internals
-=============
 
-There are two object abstractions: the "object database", and the
-"current directory cache" aka "index".
+We already saw in <<understanding-commits>> that all commits are stored
+under a 40-digit "object name".  In fact, all the information needed to
+represent the history of a project is stored in objects with such names.
+In each case the name is calculated by taking the SHA-1 hash of the
+contents of the object.  The SHA-1 hash is a cryptographic hash function.
+What that means to us is that it is impossible to find two different
+objects with the same name.  This has a number of advantages; among
+others:
+
+- Git can quickly determine whether two objects are identical or not,
+  just by comparing names.
+- Since object names are computed the same way in every repository, the
+  same content stored in two repositories will always be stored under
+  the same name.
+- Git can detect errors when it reads an object, by checking that the
+  object's name is still the SHA-1 hash of its contents.
+
+(See <<object-details>> for the details of the object formatting and
+SHA-1 calculation.)
+
+There are four different types of objects: "blob", "tree", "commit", and
+"tag".
+
+- A <<def_blob_object,"blob" object>> is used to store file data.
+- A <<def_tree_object,"tree" object>> ties one or more
+  "blob" objects into a directory structure. In addition, a tree object
+  can refer to other tree objects, thus creating a directory hierarchy.
+- A <<def_commit_object,"commit" object>> ties such directory hierarchies
+  together into a <<def_DAG,directed acyclic graph>> of revisions--each
+  commit contains the object name of exactly one tree designating the
+  directory hierarchy at the time of the commit. In addition, a commit
+  refers to "parent" commit objects that describe the history of how we
+  arrived at that directory hierarchy.
+- A <<def_tag_object,"tag" object>> symbolically identifies and can be
+  used to sign other objects. It contains the object name and type of
+  another object, a symbolic name (of course!) and, optionally, a
+  signature.
 
-The Object Database
--------------------
+The object types in some more detail:
 
-The object database is literally just a content-addressable collection
-of objects.  All objects are named by their content, which is
-approximated by the SHA1 hash of the object itself.  Objects may refer
-to other objects (by referencing their SHA1 hash), and so you can
-build up a hierarchy of objects.
+[[commit-object]]
+Commit Object
+~~~~~~~~~~~~~
 
-All objects have a statically determined "type" aka "tag", which is
-determined at object creation time, and which identifies the format of
-the object (i.e. how it is used, and how it can refer to other
-objects).  There are currently four different object types: "blob",
-"tree", "commit" and "tag".
-
-A "blob" object cannot refer to any other object, and is, like the type
-implies, a pure storage object containing some user data.  It is used to
-actually store the file data, i.e. a blob object is associated with some
-particular version of some file. 
-
-A "tree" object is an object that ties one or more "blob" objects into a
-directory structure. In addition, a tree object can refer to other tree
-objects, thus creating a directory hierarchy. 
-
-A "commit" object ties such directory hierarchies together into
-a DAG of revisions - each "commit" is associated with exactly one tree
-(the directory hierarchy at the time of the commit). In addition, a
-"commit" refers to one or more "parent" commit objects that describe the
-history of how we arrived at that directory hierarchy.
-
-As a special case, a commit object with no parents is called the "root"
-object, and is the point of an initial project commit.  Each project
-must have at least one root, and while you can tie several different
-root objects together into one project by creating a commit object which
-has two or more separate roots as its ultimate parents, that's probably
-just going to confuse people.  So aim for the notion of "one root object
-per project", even if git itself does not enforce that. 
-
-A "tag" object symbolically identifies and can be used to sign other
-objects. It contains the identifier and type of another object, a
-symbolic name (of course!) and, optionally, a signature.
+The "commit" object links a physical state of a tree with a description
+of how we got there and why.  Use the `--pretty=raw` option to
+linkgit:git-show[1] or linkgit:git-log[1] to examine your favorite
+commit:
 
-Regardless of object type, all objects share the following
-characteristics: they are all deflated with zlib, and have a header
-that not only specifies their type, but also provides size information
-about the data in the object.  It's worth noting that the SHA1 hash
-that is used to name the object is the hash of the original data
-plus this header, so `sha1sum` 'file' does not match the object name
-for 'file'.
-(Historical note: in the dawn of the age of git the hash
-was the sha1 of the 'compressed' object.)

-As a result, the general consistency of an object can always be tested

+------------------------------------------------
 
-The object types in some more detail:
+As you can see, a commit is defined by:
+
+- a tree: The SHA-1 name of a tree object (as defined below), representing
+  the contents of a directory at a certain point in time.
+- parent(s): The SHA-1 name(s) of some number of commits which represent the
+  immediately previous step(s) in the history of the project.  The
+  example above has one parent; merge commits may have more than
+  one.  A commit with no parents is called a "root" commit, and
+  represents the initial revision of a project.  Each project must have
+  at least one root.  A project can also have multiple roots, though
+  that isn't common (or necessarily a good idea).
+- an author: The name of the person responsible for this change, together
+  with its date.
+- a committer: The name of the person who actually created the commit,
+  with the date it was done.  This may be different from the author, for
+  example, if the author was someone who wrote a patch and emailed it
+  to the person who used it to create the commit.
+- a comment describing this commit.
+
+Note that a commit does not itself contain any information about what
+actually changed; all changes are calculated by comparing the contents
+of the tree referred to by this commit with the trees associated with
+its parents.  In particular, Git does not attempt to record file renames
+explicitly, though it can identify cases where the existence of the same
+file data at changing paths suggests a rename.  (See, for example, the
+`-M` option to linkgit:git-diff[1]).
+
+A commit is usually created by linkgit:git-commit[1], which creates a
+commit whose parent is normally the current HEAD, and whose tree is
+taken from the content currently stored in the index.

+mode, object type, SHA-1 name, and name, sorted by name.  It represents
+the contents of a single directory tree.
 
-In particular, since the blob is entirely defined by its data, if two
-files in a directory tree (or in multiple different versions of the
-repository) have the same contents, they will share the same blob
-object. The object is totally independent of its location in the
-directory tree, and renaming a file does not change the object that
-file is associated with in any way.
+The object type may be a blob, representing the contents of a file, or
+another tree, representing the contents of a subdirectory.  Since trees
+and blobs, like all other objects, are named by the SHA-1 hash of their
+contents, two trees have the same SHA-1 name if and only if their
+contents (including, recursively, the contents of all subdirectories)
+are identical.  This allows Git to quickly determine the differences
+between two related tree objects, since it can ignore any entries with
+identical object names.
 
-A blob is typically created when gitlink:git-update-index[1]
-is run, and its data can be accessed by gitlink:git-cat-file[1].
+(Note: in the presence of submodules, trees may also have commits as
+entries.  See <<submodules>> for documentation.)
 
-Tree Object
------------
+Note that the files all have mode 644 or 755: Git actually only pays
+attention to the executable bit.
 
-The next hierarchical object type is the "tree" object.  A tree object
-is a list of mode/name/blob data, sorted by name.  Alternatively, the
-mode data may specify a directory mode, in which case instead of
-naming a blob, that name is associated with another TREE object.
-
-Like the "blob" object, a tree object is uniquely determined by the
-set contents, and so two separate but identical trees will always
-share the exact same object. This is true at all levels, i.e. it's
-true for a "leaf" tree (which does not refer to any other trees, only
-blobs) as well as for a whole subdirectory.
-
-For that reason a "tree" object is just a pure data abstraction: it
-has no history, no signatures, no verification of validity, except
-that since the contents are again protected by the hash itself, we can
-trust that the tree is immutable and its contents never change.
-
-So you can trust the contents of a tree to be valid, the same way you
-can trust the contents of a blob, but you don't know where those
-contents 'came' from.
-
-Side note on trees: since a "tree" object is a sorted list of
-"filename+content", you can create a diff between two trees without
-actually having to unpack two trees.  Just ignore all common parts,
-and your diff will look right.  In other words, you can effectively
-(and efficiently) tell the difference between any two random trees by
-O(n) where "n" is the size of the difference, rather than the size of
-the tree.
-
-Side note 2 on trees: since the name of a "blob" depends entirely and
-exclusively on its contents (i.e. there are no names or permissions
-involved), you can see trivial renames or permission changes by
-noticing that the blob stayed the same.  However, renames with data
-changes need a smarter "diff" implementation.
-
-A tree is created with gitlink:git-write-tree[1] and
-its data can be accessed by gitlink:git-ls-tree[1].
-Two trees can be compared with gitlink:git-diff-tree[1].

+Blob Object
+~~~~~~~~~~~
 
-Commit Object
--------------
+You can use linkgit:git-show[1] to examine the contents of a blob; take,
+for example, the blob in the entry for `COPYING` from the tree above:
+
+------------------------------------------------
+$ git show 6ff87c4664
 
-The "commit" object is an object that introduces the notion of
-history into the picture.  In contrast to the other objects, it
-doesn't just describe the physical state of a tree, it describes how
-we got there, and why.
-
-A "commit" is defined by the tree-object that it results in, the
-parent commits (zero, one or more) that led up to that point, and a
-comment on what happened.  Again, a commit is not trusted per se:
-the contents are well-defined and "safe" due to the cryptographically
-strong signatures at all levels, but there is no reason to believe
-that the tree is "good" or that the merge information makes sense.
-The parents do not have to actually have any relationship with the
-result, for example.
-
-Note on commits: unlike real SCM's, commits do not contain
-rename information or file mode change information.  All of that is
-implicit in the trees involved (the result tree, and the result trees
-of the parents), and describing that makes no sense in this idiotic
-file manager.
-
-A commit is created with gitlink:git-commit-tree[1] and
-its data can be accessed by gitlink:git-cat-file[1].
+ Note that the only valid version of the GPL as far as this project
+ is concerned is _this_ particular version of the license (ie v2, not
+ v2.2 or v3.x or whatever), unless explicitly otherwise stated.
+...
+------------------------------------------------
+
+A "blob" object is nothing but a binary blob of data.  It doesn't refer
+to anything else or have attributes of any kind.
+
+Since the blob is entirely defined by its data, if two files in a
+directory tree (or in multiple different versions of the repository)
+have the same contents, they will share the same blob object. The object
+is totally independent of its location in the directory tree, and
+renaming a file does not change the object that file is associated with.
+
+Note that any tree or blob object can be examined using
+linkgit:git-show[1] with the <revision>:<path> syntax.  This can
+sometimes be useful for browsing the contents of a tree that is not
+currently checked out.
 
+[[trust]]
 Trust
------
+~~~~~
 
-An aside on the notion of "trust". Trust is really outside the scope
-of "git", but it's worth noting a few things.  First off, since
-everything is hashed with SHA1, you 'can' trust that an object is
-intact and has not been messed with by external sources.  So the name
-of an object uniquely identifies a known state - just not a state that
-you may want to trust.
+If you receive the SHA-1 name of a blob from one source, and its contents
+from another (possibly untrusted) source, you can still trust that those
+contents are correct as long as the SHA-1 name agrees.  This is because
+the SHA-1 is designed so that it is infeasible to find different contents
+that produce the same hash.
 
-Furthermore, since the SHA1 signature of a commit refers to the
-SHA1 signatures of the tree it is associated with and the signatures
-of the parent, a single named commit specifies uniquely a whole set
-of history, with full contents.  You can't later fake any step of the
-way once you have the name of a commit.
+Similarly, you need only trust the SHA-1 name of a top-level tree object
+to trust the contents of the entire directory that it refers to, and if
+you receive the SHA-1 name of a commit from a trusted source, then you
+can easily verify the entire history of commits reachable through
+parents of that commit, and all of those contents of the trees referred
+to by those commits.
 
 So to introduce some real trust in the system, the only thing you need
 to do is to digitally sign just 'one' special note, which includes the
@@ -2448,161 +3128,730 @@ that you trust that commit, and the immutability of the history of
 commits tells others that they can trust the whole history.
 
 In other words, you can easily validate a whole archive by just

 Tag Object
-----------
+~~~~~~~~~~
 
-Git provides the "tag" object to simplify creating, managing and
-exchanging symbolic and signed tokens.  The "tag" object at its
-simplest simply symbolically identifies another object by containing
-the sha1, type and symbolic name.
+A tag object contains an object, object type, tag name, the name of the
+person ("tagger") who created the tag, and a message, which may contain
+a signature, as can be seen using linkgit:git-cat-file[1]:
 
-However it can optionally contain additional signature information
-(which git doesn't care about as long as there's less than 8k of
-it). This can then be verified externally to git.

+[[pack-files]]
+How Git stores objects efficiently: pack files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
+Newly created objects are initially created in a file named after the
+object's SHA-1 hash (stored in `.git/objects`).
 
-The "index" aka "Current Directory Cache"
------------------------------------------
+Unfortunately this system becomes inefficient once a project has a
+lot of objects.  Try this on an old project:
+
+------------------------------------------------
+$ git count-objects
+6930 objects, 47620 kilobytes
+------------------------------------------------
+
+The first number is the number of objects which are kept in
+individual files.  The second is the amount of space taken up by
+those "loose" objects.
+
+You can save space and make Git faster by moving these loose objects in
+to a "pack file", which stores a group of objects in an efficient
+compressed format; the details of how pack files are formatted can be
+found in link:technical/pack-format.html[pack format].
+
+To put the loose objects into a pack, just run git repack:
+
+------------------------------------------------
+$ git repack
+Counting objects: 6020, done.
+Delta compression using up to 4 threads.
+Compressing objects: 100% (6020/6020), done.
+Writing objects: 100% (6020/6020), done.
+Total 6020 (delta 4070), reused 0 (delta 0)
+------------------------------------------------
+
+This creates a single "pack file" in .git/objects/pack/
+containing all currently unpacked objects.  You can then run
+
+------------------------------------------------
+$ git prune
+------------------------------------------------
+
+to remove any of the "loose" objects that are now contained in the
+pack.  This will also remove any unreferenced objects (which may be
+created when, for example, you use `git reset` to remove a commit).
+You can verify that the loose objects are gone by looking at the
+`.git/objects` directory or by running
+
+------------------------------------------------
+$ git count-objects
+0 objects, 0 kilobytes
+------------------------------------------------
+
+Although the object files are gone, any commands that refer to those
+objects will work exactly as they did before.
+
+The linkgit:git-gc[1] command performs packing, pruning, and more for
+you, so is normally the only high-level command you need.
+
+[[dangling-objects]]
+Dangling objects
+~~~~~~~~~~~~~~~~
+
+The linkgit:git-fsck[1] command will sometimes complain about dangling
+objects.  They are not a problem.
+
+The most common cause of dangling objects is that you've rebased a
+branch, or you have pulled from somebody else who rebased a branch--see
+<<cleaning-up-history>>.  In that case, the old head of the original
+branch still exists, as does everything it pointed to. The branch
+pointer itself just doesn't, since you replaced it with another one.
+
+There are also other situations that cause dangling objects. For
+example, a "dangling blob" may arise because you did a `git add` of a
+file, but then, before you actually committed it and made it part of the
+bigger picture, you changed something else in that file and committed
+that *updated* thing--the old state that you added originally ends up
+not being pointed to by any commit or tree, so it's now a dangling blob
+object.
+
+Similarly, when the "recursive" merge strategy runs, and finds that
+there are criss-cross merges and thus more than one merge base (which is
+fairly unusual, but it does happen), it will generate one temporary
+midway tree (or possibly even more, if you had lots of criss-crossing
+merges and more than two merge bases) as a temporary internal merge
+base, and again, those are real objects, but the end result will not end
+up pointing to them, so they end up "dangling" in your repository.
+
+Generally, dangling objects aren't anything to worry about. They can
+even be very useful: if you screw something up, the dangling objects can
+be how you recover your old tree (say, you did a rebase, and realized
+that you really didn't want to--you can look at what dangling objects
+you have, and decide to reset your head to some old dangling state).
+
+For commits, you can just use:
+
+------------------------------------------------
+$ gitk <dangling-commit-sha-goes-here> --not --all
+------------------------------------------------
+
+This asks for all the history reachable from the given commit but not
+from any branch, tag, or other reference.  If you decide it's something
+you want, you can always create a new reference to it, e.g.,
+
+------------------------------------------------
+$ git branch recovered-branch <dangling-commit-sha-goes-here>
+------------------------------------------------
+
+For blobs and trees, you can't do the same, but you can still examine
+them.  You can just do
+
+------------------------------------------------
+$ git show <dangling-blob/tree-sha-goes-here>
+------------------------------------------------
+
+to show what the contents of the blob were (or, for a tree, basically
+what the `ls` for that directory was), and that may give you some idea
+of what the operation was that left that dangling object.
+
+Usually, dangling blobs and trees aren't very interesting. They're
+almost always the result of either being a half-way mergebase (the blob
+will often even have the conflict markers from a merge in it, if you
+have had conflicting merges that you fixed up by hand), or simply
+because you interrupted a `git fetch` with ^C or something like that,
+leaving _some_ of the new objects in the object database, but just
+dangling and useless.
+
+Anyway, once you are sure that you're not interested in any dangling
+state, you can just prune all unreachable objects:
+
+------------------------------------------------
+$ git prune
+------------------------------------------------
+
+and they'll be gone. (You should only run `git prune` on a quiescent
+repository--it's kind of like doing a filesystem fsck recovery: you
+don't want to do that while the filesystem is mounted.
+`git prune` is designed not to cause any harm in such cases of concurrent
+accesses to a repository but you might receive confusing or scary messages.)
+
+[[recovering-from-repository-corruption]]
+Recovering from repository corruption
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By design, Git treats data trusted to it with caution.  However, even in
+the absence of bugs in Git itself, it is still possible that hardware or
+operating system errors could corrupt data.
+
+The first defense against such problems is backups.  You can back up a
+Git directory using clone, or just using cp, tar, or any other backup
+mechanism.
+
+As a last resort, you can search for the corrupted objects and attempt
+to replace them by hand.  Back up your repository before attempting this
+in case you corrupt things even more in the process.
+
+We'll assume that the problem is a single missing or corrupted blob,
+which is sometimes a solvable problem.  (Recovering missing trees and
+especially commits is *much* harder).
+
+Before starting, verify that there is corruption, and figure out where
+it is with linkgit:git-fsck[1]; this may be time-consuming.
+
+Assume the output looks like this:
+
+------------------------------------------------
+$ git fsck --full --no-dangling
+broken link from    tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8
+              to    blob 4b9458b3786228369c63936db65827de3cc06200
+missing blob 4b9458b3786228369c63936db65827de3cc06200
+------------------------------------------------
 
-The index is a simple binary file, which contains an efficient
-representation of a virtual directory content at some random time.  It
-does so by a simple array that associates a set of names, dates,
-permissions and content (aka "blob") objects together.  The cache is
-always kept ordered by name, and names are unique (with a few very
-specific rules) at any point in time, but the cache has no long-term
-meaning, and can be partially updated at any time.
-
-In particular, the index certainly does not need to be consistent with
-the current directory contents (in fact, most operations will depend on
-different ways to make the index 'not' be consistent with the directory
-hierarchy), but it has three very important attributes:
-
-'(a) it can re-generate the full state it caches (not just the
-directory structure: it contains pointers to the "blob" objects so
-that it can regenerate the data too)'
-
-As a special case, there is a clear and unambiguous one-way mapping
-from a current directory cache to a "tree object", which can be
-efficiently created from just the current directory cache without
-actually looking at any other data.  So a directory cache at any one
-time uniquely specifies one and only one "tree" object (but has
-additional data to make it easy to match up that tree object with what
-has happened in the directory)
-
-'(b) it has efficient methods for finding inconsistencies between that
-cached state ("tree object waiting to be instantiated") and the
-current state.'
-
-'(c) it can additionally efficiently represent information about merge
-conflicts between different tree objects, allowing each pathname to be
+Now you know that blob 4b9458b3 is missing, and that the tree 2d9263c6
+points to it.  If you could find just one copy of that missing blob
+object, possibly in some other repository, you could move it into
+`.git/objects/4b/9458b3...` and be done.  Suppose you can't.  You can
+still examine the tree that pointed to it with linkgit:git-ls-tree[1],
+which might output something like:
+
+------------------------------------------------
+$ git ls-tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8
+100644 blob 8d14531846b95bfa3564b58ccfb7913a034323b8	.gitignore
+100644 blob ebf9bf84da0aab5ed944264a5db2a65fe3a3e883	.mailmap
+100644 blob ca442d313d86dc67e0a2e5d584b465bd382cbf5c	COPYING
+...
+100644 blob 4b9458b3786228369c63936db65827de3cc06200	myfile
+...
+------------------------------------------------
+
+So now you know that the missing blob was the data for a file named
+`myfile`.  And chances are you can also identify the directory--let's
+say it's in `somedirectory`.  If you're lucky the missing copy might be
+the same as the copy you have checked out in your working tree at
+`somedirectory/myfile`; you can test whether that's right with
+linkgit:git-hash-object[1]:
+
+------------------------------------------------
+$ git hash-object -w somedirectory/myfile
+------------------------------------------------
+
+which will create and store a blob object with the contents of
+somedirectory/myfile, and output the SHA-1 of that object.  if you're
+extremely lucky it might be 4b9458b3786228369c63936db65827de3cc06200, in
+which case you've guessed right, and the corruption is fixed!
+
+Otherwise, you need more information.  How do you tell which version of
+the file has been lost?
+
+The easiest way to do this is with:
+
+------------------------------------------------
+$ git log --raw --all --full-history -- somedirectory/myfile
+------------------------------------------------
+
+Because you're asking for raw output, you'll now get something like
+
+------------------------------------------------
+commit abc
+Author:
+Date:
+...
+:100644 100644 4b9458b... newsha... M somedirectory/myfile
+
+
+commit xyz
+Author:
+Date:
+
+...
+:100644 100644 oldsha... 4b9458b... M somedirectory/myfile
+------------------------------------------------
+
+This tells you that the immediately following version of the file was
+"newsha", and that the immediately preceding version was "oldsha".
+You also know the commit messages that went with the change from oldsha
+to 4b9458b and with the change from 4b9458b to newsha.
+
+If you've been committing small enough changes, you may now have a good
+shot at reconstructing the contents of the in-between state 4b9458b.
+
+If you can do that, you can now recreate the missing object with
+
+------------------------------------------------
+$ git hash-object -w <recreated-file>
+------------------------------------------------
+
+and your repository is good again!
+
+(Btw, you could have ignored the `fsck`, and started with doing a
+
+------------------------------------------------
+$ git log --raw --all
+------------------------------------------------
+
+and just looked for the sha of the missing object (4b9458b..) in that
+whole thing. It's up to you--Git does *have* a lot of information, it is
+just missing one particular blob version.
+
+[[the-index]]
+The index
+-----------
+
+The index is a binary file (generally kept in `.git/index`) containing a
+sorted list of path names, each with permissions and the SHA-1 of a blob
+object; linkgit:git-ls-files[1] can show you the contents of the index:
+
+-------------------------------------------------
+$ git ls-files --stage

+-------------------------------------------------
+
+Note that in older documentation you may see the index called the
+"current directory cache" or just the "cache".  It has three important
+properties:
+
+1. The index contains all the information necessary to generate a single
+(uniquely determined) tree object.
++
+For example, running linkgit:git-commit[1] generates this tree object
+from the index, stores it in the object database, and uses it as the
+tree object associated with the new commit.
+
+2. The index enables fast comparisons between the tree object it defines
+and the working tree.
++
+It does this by storing some additional data for each entry (such as
+the last modified time).  This data is not displayed above, and is not
+stored in the created tree object, but it can be used to determine
+quickly which files in the working directory differ from what was
+stored in the index, and thus save Git from having to read all of the
+data from such files to look for changes.
+
+3. It can efficiently represent information about merge conflicts
+between different tree objects, allowing each pathname to be
 associated with sufficient information about the trees involved that
-you can create a three-way merge between them.'
+you can create a three-way merge between them.
++
+We saw in <<conflict-resolution>> that during a merge the index can
+store multiple versions of a single file (called "stages").  The third
+column in the linkgit:git-ls-files[1] output above is the stage
+number, and will take on values other than 0 for files with merge
+conflicts.
+
+The index is thus a sort of temporary staging area, which is filled with
+a tree which you are in the process of working on.
+
+If you blow the index away entirely, you generally haven't lost any
+information as long as you have the name of the tree that it described.
+
+[[submodules]]
+Submodules
+==========
+
+Large projects are often composed of smaller, self-contained modules.  For
+example, an embedded Linux distribution's source tree would include every
+piece of software in the distribution with some local modifications; a movie
+player might need to build against a specific, known-working version of a
+decompression library; several independent programs might all share the same
+build scripts.
+
+With centralized revision control systems this is often accomplished by
+including every module in one single repository.  Developers can check out
+all modules or only the modules they need to work with.  They can even modify
+files across several modules in a single commit while moving things around
+or updating APIs and translations.
+
+Git does not allow partial checkouts, so duplicating this approach in Git
+would force developers to keep a local copy of modules they are not
+interested in touching.  Commits in an enormous checkout would be slower
+than you'd expect as Git would have to scan every directory for changes.
+If modules have a lot of local history, clones would take forever.
+
+On the plus side, distributed revision control systems can much better
+integrate with external sources.  In a centralized model, a single arbitrary
+snapshot of the external project is exported from its own revision control
+and then imported into the local revision control on a vendor branch.  All
+the history is hidden.  With distributed revision control you can clone the
+entire external history and much more easily follow development and re-merge
+local changes.
+
+Git's submodule support allows a repository to contain, as a subdirectory, a
+checkout of an external project.  Submodules maintain their own identity;
+the submodule support just stores the submodule repository location and
+commit ID, so other developers who clone the containing project
+("superproject") can easily clone all the submodules at the same revision.
+Partial checkouts of the superproject are possible: you can tell Git to
+clone none, some or all of the submodules.
+
+The linkgit:git-submodule[1] command is available since Git 1.5.3.  Users
+with Git 1.5.2 can look up the submodule commits in the repository and
+manually check them out; earlier versions won't recognize the submodules at
+all.
+
+To see how submodule support works, create four example
+repositories that can be used later as a submodule:
+
+-------------------------------------------------
+$ mkdir ~/git
+$ cd ~/git
+$ for i in a b c d
+do
+	mkdir $i
+	cd $i
+	git init
+	echo "module $i" > $i.txt
+	git add $i.txt
+	git commit -m "Initial commit, submodule $i"
+	cd ..
+done
+-------------------------------------------------
+
+Now create the superproject and add all the submodules:
+
+-------------------------------------------------
+$ mkdir super
+$ cd super
+$ git init
+$ for i in a b c d
+do
+	git submodule add ~/git/$i $i
+done
+-------------------------------------------------
+
+NOTE: Do not use local URLs here if you plan to publish your superproject!
+
+See what files `git submodule` created:
+
+-------------------------------------------------
+$ ls -a
+.  ..  .git  .gitmodules  a  b  c  d
+-------------------------------------------------
+
+The `git submodule add <repo> <path>` command does a couple of things:
+
+- It clones the submodule from `<repo>` to the given `<path>` under the
+  current directory and by default checks out the master branch.
+- It adds the submodule's clone path to the linkgit:gitmodules[5] file and
+  adds this file to the index, ready to be committed.
+- It adds the submodule's current commit ID to the index, ready to be
+  committed.
+
+Commit the superproject:
+
+-------------------------------------------------
+$ git commit -m "Add submodules a, b, c and d."
+-------------------------------------------------
+
+Now clone the superproject:
+
+-------------------------------------------------
+$ cd ..

+-------------------------------------------------
+
+NOTE: The commit object names shown above would be different for you, but they
+should match the HEAD commit object names of your repositories.  You can check
+it by running `git ls-remote ../a`.
+
+Pulling down the submodules is a two-step process. First run `git submodule
+init` to add the submodule repository URLs to `.git/config`:
+
+-------------------------------------------------
+$ git submodule init
+-------------------------------------------------
+
+Now use `git submodule update` to clone the repositories and check out the
+commits specified in the superproject:
+
+-------------------------------------------------
+$ git submodule update
+$ cd a
+$ ls -a
+.  ..  .git  a.txt

-Those are the ONLY three things that the directory cache does.  It's a
-cache, and the normal operation is to re-generate it completely from a
-known tree object, or update/compare it with a live tree that is being
-developed.  If you blow the directory cache away entirely, you generally
-haven't lost any information as long as you have the name of the tree
-that it described. 
+One major difference between `git submodule update` and `git submodule add` is
+that `git submodule update` checks out a specific commit, rather than the tip
+of a branch. It's like checking out a tag: the head is detached, so you're not
+working on a branch.
 
-At the same time, the index is at the same time also the
-staging area for creating new trees, and creating a new tree always
-involves a controlled modification of the index file.  In particular,
-the index file can have the representation of an intermediate tree that
-has not yet been instantiated.  So the index can be thought of as a
-write-back cache, which can contain dirty information that has not yet
-been written back to the backing store.

+objects).  There are currently four different object types: "blob",
+"tree", "commit", and "tag".
 
-The first number is the number of objects which are kept in
-individual files.  The second is the amount of space taken up by
-those "loose" objects.
+Regardless of object type, all objects share the following
+characteristics: they are all deflated with zlib, and have a header
+that not only specifies their type, but also provides size information
+about the data in the object.  It's worth noting that the SHA-1 hash
+that is used to name the object is the hash of the original data
+plus this header, so `sha1sum` 'file' does not match the object name
+for 'file'.
 
-You can save space and make git faster by moving these loose objects in
-to a "pack file", which stores a group of objects in an efficient
-compressed format; the details of how pack files are formatted can be
-found in link:technical/pack-format.txt[technical/pack-format.txt].
+As a result, the general consistency of an object can always be tested
+independently of the contents or the type of the object: all objects can
+be validated by verifying that (a) their hashes match the content of the
+file and (b) the object successfully inflates to a stream of bytes that
+forms a sequence of
+`<ascii type without space> + <space> + <ascii decimal size> +
+<byte\0> + <binary object data>`.
 
-To put the loose objects into a pack, just run git repack:
+The structured objects can further have their structure and
+connectivity to other objects verified. This is generally done with
+the `git fsck` program, which generates a full dependency graph
+of all objects, and verifies their internal consistency (in addition
+to just verifying their superficial consistency through the hash).

+It is not always easy for new developers to find their way through Git's
+source code.  This section gives you a little guidance to show where to
+start.
 
-------------------------------------------------
-$ git prune
-------------------------------------------------
+A good place to start is with the contents of the initial commit, with:
 
-to remove any of the "loose" objects that are now contained in the
-pack.  This will also remove any unreferenced objects (which may be
-created when, for example, you use "git reset" to remove a commit).
-You can verify that the loose objects are gone by looking at the
-.git/objects directory or by running
+----------------------------------------------------
+$ git checkout e83c5163
+----------------------------------------------------
 
-------------------------------------------------
-$ git count-objects
-0 objects, 0 kilobytes
-------------------------------------------------
+The initial revision lays the foundation for almost everything Git has
+today, but is small enough to read in one sitting.
 
-Although the object files are gone, any commands that refer to those
-objects will work exactly as they did before.
+Note that terminology has changed since that revision.  For example, the
+README in that revision uses the word "changeset" to describe what we
+now call a <<def_commit_object,commit>>.
 
-The gitlink:git-gc[1] command performs packing, pruning, and more for
-you, so is normally the only high-level command you need.
+Also, we do not call it "cache" any more, but rather "index"; however, the
+file is still called `cache.h`.  Remark: Not much reason to change it now,
+especially since there is no good single name for it anyway, because it is
+basically _the_ header file which is included by _all_ of Git's C sources.
 
-[[dangling-objects]]
-Dangling objects
-----------------
+If you grasp the ideas in that initial commit, you should check out a
+more recent version and skim `cache.h`, `object.h` and `commit.h`.
 
-The gitlink:git-fsck[1] command will sometimes complain about dangling
-objects.  They are not a problem.
+In the early days, Git (in the tradition of UNIX) was a bunch of programs
+which were extremely simple, and which you used in scripts, piping the
+output of one into another. This turned out to be good for initial
+development, since it was easier to test new things.  However, recently
+many of these parts have become builtins, and some of the core has been
+"libified", i.e. put into libgit.a for performance, portability reasons,
+and to avoid code duplication.
 
-The most common cause of dangling objects is that you've rebased a
-branch, or you have pulled from somebody else who rebased a branch--see
-<<cleaning-up-history>>.  In that case, the old head of the original
-branch still exists, as does obviously everything it pointed to. The
-branch pointer itself just doesn't, since you replaced it with another
-one.
+By now, you know what the index is (and find the corresponding data
+structures in `cache.h`), and that there are just a couple of object types
+(blobs, trees, commits and tags) which inherit their common structure from
+`struct object`, which is their first member (and thus, you can cast e.g.
+`(struct object *)commit` to achieve the _same_ as `&commit->object`, i.e.
+get at the object name and flags).
 
-There are also other situations too that cause dangling objects. For
-example, a "dangling blob" may arise because you did a "git add" of a
-file, but then, before you actually committed it and made it part of the
-bigger picture, you changed something else in that file and committed
-that *updated* thing - the old state that you added originally ends up
-not being pointed to by any commit or tree, so it's now a dangling blob
-object.
+Now is a good point to take a break to let this information sink in.
 
-Similarly, when the "recursive" merge strategy runs, and finds that
-there are criss-cross merges and thus more than one merge base (which is
-fairly unusual, but it does happen), it will generate one temporary
-midway tree (or possibly even more, if you had lots of criss-crossing
-merges and more than two merge bases) as a temporary internal merge
-base, and again, those are real objects, but the end result will not end
-up pointing to them, so they end up "dangling" in your repository.
+Next step: get familiar with the object naming.  Read <<naming-commits>>.
+There are quite a few ways to name an object (and not only revisions!).
+All of these are handled in `sha1_name.c`. Just have a quick look at
+the function `get_sha1()`. A lot of the special handling is done by
+functions like `get_sha1_basic()` or the likes.
 
-Generally, dangling objects aren't anything to worry about. They can
-even be very useful: if you screw something up, the dangling objects can
-be how you recover your old tree (say, you did a rebase, and realized
-that you really didn't want to - you can look at what dangling objects
-you have, and decide to reset your head to some old dangling state).
+This is just to get you into the groove for the most libified part of Git:
+the revision walker.
 
-For commits, the most useful thing to do with dangling objects tends to
-be to do a simple
+Basically, the initial version of `git log` was a shell script:
 
-------------------------------------------------
-$ gitk <dangling-commit-sha-goes-here> --not --all
-------------------------------------------------
+----------------------------------------------------------------
+$ git-rev-list --pretty $(git-rev-parse --default HEAD "$@") | \
+	LESS=-S ${PAGER:-less}
+----------------------------------------------------------------
 
-For blobs and trees, you can't do the same, but you can examine them.
-You can just do
+What does this mean?
 
-------------------------------------------------
-$ git show <dangling-blob/tree-sha-goes-here>
-------------------------------------------------
+`git rev-list` is the original version of the revision walker, which
+_always_ printed a list of revisions to stdout.  It is still functional,
+and needs to, since most new Git commands start out as scripts using
+`git rev-list`.
 
-to show what the contents of the blob were (or, for a tree, basically
-what the "ls" for that directory was), and that may give you some idea
-of what the operation was that left that dangling object.
+`git rev-parse` is not as important any more; it was only used to filter out
+options that were relevant for the different plumbing commands that were
+called by the script.
 
-Usually, dangling blobs and trees aren't very interesting. They're
-almost always the result of either being a half-way mergebase (the blob
-will often even have the conflict markers from a merge in it, if you
-have had conflicting merges that you fixed up by hand), or simply
-because you interrupted a "git fetch" with ^C or something like that,
-leaving _some_ of the new objects in the object database, but just
-dangling and useless.
+Most of what `git rev-list` did is contained in `revision.c` and
+`revision.h`.  It wraps the options in a struct named `rev_info`, which
+controls how and what revisions are walked, and more.
 
-Anyway, once you are sure that you're not interested in any dangling 
-state, you can just prune all unreachable objects:
+The original job of `git rev-parse` is now taken by the function
+`setup_revisions()`, which parses the revisions and the common command-line
+options for the revision walker. This information is stored in the struct
+`rev_info` for later consumption. You can do your own command-line option
+parsing after calling `setup_revisions()`. After that, you have to call
+`prepare_revision_walk()` for initialization, and then you can get the
+commits one by one with the function `get_revision()`.
+
+If you are interested in more details of the revision walking process,
+just have a look at the first implementation of `cmd_log()`; call
+`git show v1.3.0~155^2~4` and scroll down to that function (note that you
+no longer need to call `setup_pager()` directly).
+
+Nowadays, `git log` is a builtin, which means that it is _contained_ in the
+command `git`.  The source side of a builtin is
+
+- a function called `cmd_<bla>`, typically defined in `builtin/<bla.c>`
+  (note that older versions of Git used to have it in `builtin-<bla>.c`
+  instead), and declared in `builtin.h`.
+
+- an entry in the `commands[]` array in `git.c`, and
+
+- an entry in `BUILTIN_OBJECTS` in the `Makefile`.
+
+Sometimes, more than one builtin is contained in one source file.  For
+example, `cmd_whatchanged()` and `cmd_log()` both reside in `builtin/log.c`,
+since they share quite a bit of code.  In that case, the commands which are
+_not_ named like the `.c` file in which they live have to be listed in
+`BUILT_INS` in the `Makefile`.
+
+`git log` looks more complicated in C than it does in the original script,
+but that allows for a much greater flexibility and performance.
+
+Here again it is a good point to take a pause.
+
+Lesson three is: study the code.  Really, it is the best way to learn about
+the organization of Git (after you know the basic concepts).
+
+So, think about something which you are interested in, say, "how can I
+access a blob just knowing the object name of it?".  The first step is to
+find a Git command with which you can do it.  In this example, it is either
+`git show` or `git cat-file`.
+
+For the sake of clarity, let's stay with `git cat-file`, because it
+
+- is plumbing, and
+
+- was around even in the initial commit (it literally went only through
+  some 20 revisions as `cat-file.c`, was renamed to `builtin/cat-file.c`
+  when made a builtin, and then saw less than 10 versions).
+
+So, look into `builtin/cat-file.c`, search for `cmd_cat_file()` and look what
+it does.
+
+------------------------------------------------------------------
+        git_config(git_default_config);
+        if (argc != 3)
+		usage("git cat-file [-t|-s|-e|-p|<type>] <sha1>");
+        if (get_sha1(argv[2], sha1))
+                die("Not a valid object name %s", argv[2]);
+------------------------------------------------------------------
+
+Let's skip over the obvious details; the only really interesting part
+here is the call to `get_sha1()`.  It tries to interpret `argv[2]` as an
+object name, and if it refers to an object which is present in the current
+repository, it writes the resulting SHA-1 into the variable `sha1`.
+
+Two things are interesting here:
+
+- `get_sha1()` returns 0 on _success_.  This might surprise some new
+  Git hackers, but there is a long tradition in UNIX to return different
+  negative numbers in case of different errors--and 0 on success.
+
+- the variable `sha1` in the function signature of `get_sha1()` is `unsigned
+  char *`, but is actually expected to be a pointer to `unsigned
+  char[20]`.  This variable will contain the 160-bit SHA-1 of the given
+  commit.  Note that whenever a SHA-1 is passed as `unsigned char *`, it
+  is the binary representation, as opposed to the ASCII representation in
+  hex characters, which is passed as `char *`.
+
+You will see both of these things throughout the code.
+
+Now, for the meat:
+
+-----------------------------------------------------------------------------
+        case 0:
+                buf = read_object_with_reference(sha1, argv[1], &size, NULL);
+-----------------------------------------------------------------------------
+
+This is how you read a blob (actually, not only a blob, but any type of
+object).  To know how the function `read_object_with_reference()` actually
+works, find the source code for it (something like `git grep
+read_object_with | grep ":[a-z]"` in the Git repository), and read
+the source.
+
+To find out how the result can be used, just read on in `cmd_cat_file()`:
+
+-----------------------------------
+        write_or_die(1, buf, size);
+-----------------------------------
+
+Sometimes, you do not know where to look for a feature.  In many such cases,
+it helps to search through the output of `git log`, and then `git show` the
+corresponding commit.
+
+Example: If you know that there was some test case for `git bundle`, but
+do not remember where it was (yes, you _could_ `git grep bundle t/`, but that
+does not illustrate the point!):
+
+------------------------
+$ git log --no-merges t/
+------------------------
+
+In the pager (`less`), just search for "bundle", go a few lines back,
+and see that it is in commit 18449ab0...  Now just copy this object name,
+and paste it into the command line
+
+-------------------
+$ git show 18449ab0
+-------------------
+
+Voila.
+
+Another example: Find out what to do in order to make some script a
+builtin:
+
+-------------------------------------------------
+$ git log --no-merges --diff-filter=A builtin/*.c
+-------------------------------------------------
+
+You see, Git is actually the best tool to find out about the source of Git
+itself!

 that uses $prefix, the built results have some paths encoded,
 which are derived from $prefix, so "make all; make prefix=/usr
 install" would not work.
 
+The beginning of the Makefile documents many variables that affect the way
+git is built.  You can override them either from the command line, or in a
+config.mak file.
+
 Alternatively you can use autoconf generated ./configure script to
 set up install paths (via config.mak.autogen), so you can write instead
 
 	$ make configure ;# as yourself

+If you're willing to trade off (much) longer build time for a later

+
+This will run the complete test suite as training workload and then
+rebuild git with the generated profile feedback. This results in a git
+which is a few percent faster on CPU intensive workloads.  This
+may be a good tradeoff for distribution packagers.
+
+Alternatively you can run profile feedback only with the git benchmark
+suite. This runs significantly faster than the full test suite, but
+has less coverage:
 
+	$ make prefix=/usr profile-fast
+	# make prefix=/usr PROFILE=BUILD install
+
+Or if you just want to install a profile-optimized version of git into
+your home directory, you could run:
+
+	$ make profile-install
+
+or
+	$ make profile-fast-install
+
+As a caveat: a profile-optimized build takes a *lot* longer since the
+git tree must be built twice, and in order for the profiling
+measurements to work properly, ccache must be disabled and the test
+suite has to be run using only a single CPU.  In addition, the profile
+feedback build stage currently generates a lot of additional compiler
+warnings.
 
 Issues of note:
 
- - git normally installs a helper script wrapper called "git", which
-   conflicts with a similarly named "GNU interactive tools" program.
+ - Ancient versions of GNU Interactive Tools (pre-4.9.2) installed a
+   program "git", whose name conflicts with this program.  But with
+   version 4.9.2, after long hiatus without active maintenance (since
+   around 1997), it changed its name to gnuit and the name conflict is no
+   longer a problem.
 
-   Tough.  Either don't use the wrapper script, or delete the old GNU
-   interactive tools.  None of the core git stuff needs the wrapper,
-   it's just a convenient shorthand and while it is documented in some
-   places, you can always replace "git commit" with "git-commit"
-   instead. 
+   NOTE: When compiled with backward compatibility option, the GNU
+   Interactive Tools package still can install "git", but you can build it
+   with --disable-transition option to avoid this.
 
-   But let's face it, most of us don't have GNU interactive tools, and
-   even if we had it, we wouldn't know what it does.  I don't think it
-   has been actively developed since 1997, and people have moved over to
-   graphical file managers.
+ - You can use git after building but without installing if you want
+   to test drive it.  Simply run git found in bin-wrappers directory
+   in the build directory, or prepend that directory to your $PATH.
+   This however is less efficient than running an installed git, as
+   you always need an extra fork+exec to run any git subcommand.
 
- - You can use git after building but without installing if you

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+# an unrelated header file changes.  Define it to "no" to use the hard-coded
+# dependency rules.  The default is "auto", which means to use computed header
+# dependencies if your compiler is detected to support it.
+#
+# Define NATIVE_CRLF if your platform uses CRLF for line endings.
+#
+# Define XDL_FAST_HASH to use an alternative line-hashing method in

+# fast unaligned word loads.  Does NOT work on big-endian systems!
+# Enabled by default on x86_64.
+#
+# Define GIT_USER_AGENT if you want to change how git identifies itself during
+# network interactions.  The default is "git/$(GIT_VERSION)".
+#
+# Define DEFAULT_HELP_FORMAT to "man", "info" or "html"
+# (defaults to "man") if you want to have a different default when
+# "git help" is called without a parameter specifying the format.
+#
+# Define TEST_GIT_INDEX_VERSION to 2, 3 or 4 to run the test suite
+# with a different indexfile format version.  If it isn't set the index
+# file format used is index-v[23].
+#
+# Define GMTIME_UNRELIABLE_ERRORS if your gmtime() function does not
+# return NULL when it receives a bogus time_t.
+#
+# Define HAVE_CLOCK_GETTIME if your platform has clock_gettime in librt.
+#
+# Define HAVE_CLOCK_MONOTONIC if your platform has CLOCK_MONOTONIC in librt.
+#
+# Define NO_HMAC_CTX_CLEANUP if your OpenSSL is version 0.9.6b or earlier to
+# cleanup the HMAC context with the older HMAC_cleanup function.
+#
+# Define USE_PARENS_AROUND_GETTEXT_N to "yes" if your compiler happily
+# compiles the following initialization:
+#
+#   static const char s[] = ("FOO");
+#
+# and define it to "no" if you need to remove the parentheses () around the

+#
+# Define HAVE_BSD_SYSCTL if your platform has a BSD-compatible sysctl function.

+### Target-specific flags and dependencies
 
-help.o: common-cmds.h
+# The generic compilation pattern rule and automatically
+# computed header dependencies (falling back to a dependency on
+# LIB_H) are enough to describe how most targets should be built,
+# but some targets are special enough to need something a little
+# different.
+#
+# - When a source file "foo.c" #includes a generated header file,
+#   we need to list that dependency for the "foo.o" target.
+#
+#   We also list it from other targets that are built from foo.c
+#   like "foo.sp" and "foo.s", even though that is easy to forget
+#   to do because the generated header is already present around
+#   after a regular build attempt.
+#
+# - Some code depends on configuration kept in makefile
+#   variables. The target-specific variable EXTRA_CPPFLAGS can
+#   be used to convey that information to the C preprocessor
+#   using -D options.
+#
+#   The "foo.o" target should have a corresponding dependency on
+#   a file that changes when the value of the makefile variable
+#   changes.  For example, targets making use of the
+#   $(GIT_VERSION) variable depend on GIT-VERSION-FILE.
+#
+#   Technically the ".sp" and ".s" targets do not need this
+#   dependency because they are force-built, but they get the
+#   same dependency for consistency. This way, you do not have to
+#   know how each target is implemented. And it means the
+#   dependencies here will not need to change if the force-build
+#   details change some day.

- *	git-checkout-index -a -f file.c
- *
- * Will first check out all files listed in the cache (but not
- * overwrite any old ones), and then force-checkout "file.c" a

- *
- * Also, just doing "git-checkout-index" does nothing. You probably
- * meant "git-checkout-index -a". And if you want to force it, you
- * want "git-checkout-index -f -a".
- *
- * Intuitiveness is not the goal here. Repeatability is. The
- * reason for the "no arguments means no work" thing is that
- * from scripts you are supposed to be able to do things like
- *
- *	find . -name '*.h' -print0 | xargs -0 git-checkout-index -f --
- *
- * or:
- *
- *	find . -name '*.h' -print0 | git-checkout-index -f -z --stdin
- *
- * which will force all existing *.h files to be replaced with
- * their cached copies. If an empty command line implied "all",
- * then this would force-refresh everything in the cache, which
- * was not the point.
- *
- * Oh, and the "--" is just a good idea when you know the rest
- * will be filenames. Just so that you wouldn't have a filename
- * of "-a" causing problems (not possible in the above example,

+
+/*
+ * define_commit_slab(slabname, elemtype) creates boilerplate code to define
+ * a new struct (struct slabname) that is used to associate a piece of data
+ * of elemtype to commits, and a few functions to use that struct.
+ *
+ * After including this header file, using:
+ *
+ * define_commit_slab(indegee, int);
+ *
+ * will let you call the following functions:
+ *
+ * - int *indegree_at(struct indegree *, struct commit *);
+ *
+ *   This function locates the data associated with the given commit in
+ *   the indegree slab, and returns the pointer to it.  The location to
+ *   store the data is allocated as necessary.
+ *
+ * - int *indegree_peek(struct indegree *, struct commit *);
+ *
+ *   This function is similar to indegree_at(), but it will return NULL
+ *   until a call to indegree_at() was made for the commit.
+ *
+ * - void init_indegree(struct indegree *);
+ *   void init_indegree_with_stride(struct indegree *, int);
+ *
+ *   Initializes the indegree slab that associates an array of integers
+ *   to each commit. 'stride' specifies how big each array is.  The slab
+ *   that is initialized by the variant without "_with_stride" associates
+ *   each commit with an array of one integer.
+ *
+ * - void clear_indegree(struct indegree *);
+ *
+ *   Empties the slab.  The slab can be reused with the same stride
+ *   without calling init_indegree() again or can be reconfigured to a
+ *   different stride by calling init_indegree_with_stride().
+ *
+ *   Call this function before the slab falls out of scope to avoid
+ *   leaking memory.

+nedalloc v1.05 15th June 2008:
+-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+by Niall Douglas (http://www.nedprod.com/programs/portable/nedmalloc/)
+
+Enclosed is nedalloc, an alternative malloc implementation for multiple
+threads without lock contention based on dlmalloc v2.8.4. It is more
+or less a newer implementation of ptmalloc2, the standard allocator in
+Linux (which is based on dlmalloc v2.7.0) but also contains a per-thread
+cache for maximum CPU scalability.
+
+It is licensed under the Boost Software License which basically means
+you can do anything you like with it. This does not apply to the malloc.c.h
+file which remains copyright to others.
+
+It has been tested on win32 (x86), win64 (x64), Linux (x64), FreeBSD (x64)
+and Apple MacOS X (x86). It works very well on all of these and is very
+significantly faster than the system allocator on all of these platforms.
+
+By literally dropping in this allocator as a replacement for your system
+allocator, you can see real world improvements of up to three times in normal
+code!
+
+To use:
+-=-=-=-
+Drop in nedmalloc.h, nedmalloc.c and malloc.c.h into your project.
+Configure using the instructions in nedmalloc.h. Run and enjoy.
+
+To test, compile test.c. It will run a comparison between your system
+allocator and nedalloc and tell you how much faster nedalloc is. It also
+serves as an example of usage.
+
+Notes:
+-=-=-=
+If you want the very latest version of this allocator, get it from the
+TnFOX SVN repository at svn://svn.berlios.de/viewcvs/tnfox/trunk/src/nedmalloc
+
+Because of how nedalloc allocates an mspace per thread, it can cause
+severe bloating of memory usage under certain allocation patterns.
+You can substantially reduce this wastage by setting MAXTHREADSINPOOL
+or the threads parameter to nedcreatepool() to a fraction of the number of
+threads which would normally be in a pool at once. This will reduce
+bloating at the cost of an increase in lock contention. If allocated size
+is less than THREADCACHEMAX, locking is avoided 90-99% of the time and
+if most of your allocations are below this value, you can safely set
+MAXTHREADSINPOOL to one.
+
+You will suffer memory leakage unless you call neddisablethreadcache()
+per pool for every thread which exits. This is because nedalloc cannot
+portably know when a thread exits and thus when its thread cache can
+be returned for use by other code. Don't forget pool zero, the system pool.
+
+For C++ type allocation patterns (where the same sizes of memory are
+regularly allocated and deallocated as objects are created and destroyed),
+the threadcache always benefits performance. If however your allocation
+patterns are different, searching the threadcache may significantly slow
+down your code - as a rule of thumb, if cache utilisation is below 80%
+(see the source for neddisablethreadcache() for how to enable debug
+printing in release mode) then you should disable the thread cache for
+that thread. You can compile out the threadcache code by setting
+THREADCACHEMAX to zero.
+
+Speed comparisons:
+-=-=-=-=-=-=-=-=-=
+See Benchmarks.xls for details.
+
+The enclosed test.c can do two things: it can be a torture test or a speed
+test. The speed test is designed to be a representative synthetic
+memory allocator test. It works by randomly mixing allocations with frees
+with half of the allocation sizes being a two power multiple less than
+512 bytes (to mimic C++ stack instantiated objects) and the other half
+being a simple random value less than 16Kb.
+
+The real world code results are from Tn's TestIO benchmark. This is a
+heavily multithreaded and memory intensive benchmark with a lot of branching
+and other stuff modern processors don't like so much. As you'll note, the
+test doesn't show the benefits of the threadcache mostly due to the saturation
+of the memory bus being the limiting factor.

+
+* Version pre-2.8.4 Mon Nov 27 11:22:37 2006    (dl at gee)
+
+   Note: There may be an updated version of this malloc obtainable at
+	   ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+	 Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.4.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+					  8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+			  8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using nedmalloc
+       (http://www.nedprod.com/programs/portable/nedmalloc/) or
+       ptmalloc (See http://www.malloc.de), which are derived
+       from versions of this malloc.
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1. In real-time
+  applications, you can optionally suppress segment traversals using
+  NO_SEGMENT_TRAVERSAL, which assures bounded execution even when
+  system allocators return non-contiguous spaces, at the typical
+  expense of carrying around more memory and increased fragmentation.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted. You can also
+use the symbolic values MAX_SIZE_T, SIZE_T_ONE, etc below.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix. Beware that there seem to be some
+  cases where this malloc might not be a pure drop-in replacement for
+  Win32 malloc: Random-looking failures from Win32 GDI API's (eg;
+  SetDIBits()) may be due to bugs in some video driver implementations
+  when pixel buffers are malloc()ed, and the region spans more than
+  one VirtualAlloc()ed region. Because dlmalloc uses a small (64Kb)
+  default granularity, pixel buffers may straddle virtual allocation
+  regions more often than when using the Microsoft allocator.  You can
+  avoid this by using VirtualAlloc() and VirtualFree() for all pixel
+  buffers rather than using malloc().  If this is not possible,
+  recompile this malloc with a larger DEFAULT_GRANULARITY.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.) If set to a
+  non-zero value other than 1, locks are used, but their
+  implementation is left out, so lock functions must be supplied manually.
+
+USE_SPIN_LOCKS           default: 1 iff USE_LOCKS and on x86 using gcc or MSC
+  If true, uses custom spin locks for locking. This is currently
+  supported only for x86 platforms using gcc or recent MS compilers.
+  Otherwise, posix locks or win32 critical sections are used.
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.
+
+MORECORE_CONTIGUOUS       default: 1 (true) if HAVE_MORECORE
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+NO_SEGMENT_TRAVERSAL       default: 0
+  If non-zero, suppresses traversals of memory segments
+  returned by either MORECORE or CALL_MMAP. This disables
+  merging of segments that are contiguous, and selectively
+  releasing them to the OS if unused, but bounds execution times.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 except on WINCE.
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero and on WIN32 except for WINCE.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. Similarly for Win32 under recent MS compilers.
+  (On most x86s, the asm version is only slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should
+  be the same as a call to free. Some people think it should. Otherwise,
+  since this malloc returns a unique pointer for malloc(0), so does
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+				system_info.dwAllocationGranularity in WIN32,
+				otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.
+
+MAX_RELEASE_CHECK_RATE   default: 4095 unless not HAVE_MMAP
+  The number of consolidated frees between checks to release
+  unused segments when freeing. When using non-contiguous segments,
+  especially with multiple mspaces, checking only for topmost space
+  doesn't always suffice to trigger trimming. To compensate for this,
+  free() will, with a period of MAX_RELEASE_CHECK_RATE (or the
+  current number of segments, if greater) try to release unused
+  segments to the OS when freeing chunks that result in
+  consolidation. The best value for this parameter is a compromise
+  between slowing down frees with relatively costly checks that
+  rarely trigger versus holding on to unused memory. To effectively
+  disable, set to MAX_SIZE_T. This may lead to a very slight speed
+  improvement at the expense of carrying around more memory.

+  independent_calloc is similar to calloc, but instead of returning a

+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or

+  is null, it returns a chunk representing an array with zero elements

+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this

+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
+    void* chunks[3];
+    if (independent_comalloc(3, sizes, chunks) == 0)
+      die();
+    struct Head* head = (struct Head*)(chunks[0]);
+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }

+  When locks are defined, there is one global lock, plus
+  one per-mspace lock.
+
+  The global lock_ensures that mparams.magic and other unique
+  mparams values are initialized only once. It also protects
+  sequences of calls to MORECORE.  In many cases sys_alloc requires
+  two calls, that should not be interleaved with calls by other
+  threads.  This does not protect against direct calls to MORECORE
+  by other threads not using this lock, so there is still code to
+  cope the best we can on interference.
+
+  Per-mspace locks surround calls to malloc, free, etc.  To enable use
+  in layered extensions, per-mspace locks are reentrant.
+
+  Because lock-protected regions generally have bounded times, it is
+  OK to use the supplied simple spinlocks in the custom versions for
+  x86.
+
+  If USE_LOCKS is > 1, the definitions of lock routines here are
+  bypassed, in which case you will need to define at least
+  INITIAL_LOCK, ACQUIRE_LOCK, RELEASE_LOCK and possibly TRY_LOCK
+  (which is not used in this malloc, but commonly needed in
+  extensions.)

+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+	   | Size of previous chunk (if P = 0)                             |

+								     +-+
+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+	the one bordering the end of available memory). It is treated
+	specially.  Top is never included in any bin, is used only if
+	no other chunk is available, and is released back to the
+	system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+	the top chunk is treated as larger (and thus less well
+	fitting) than any other available chunk.  The top chunk
+	doesn't update its trailing size field since there is no next
+	contiguous chunk that would have to index off it. However,
+	space is still allocated for it (TOP_FOOT_SIZE) to enable
+	separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, which have the lowest-order bit
+	(IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+	PINUSE_BIT in their head fields.  Because they are allocated
+	one-by-one, each must carry its own prev_foot field, which is
+	also used to hold the offset this chunk has within its mmapped
+	region, which is needed to preserve alignment. Each mmapped
+	chunk is trailed by the first two fields of a fake next-chunk
+	for sake of usage checks.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size as an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+
+/*
+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Trim support
+    Fields holding the amount of unused topmost memory that should trigger
+    timming, and a counter to force periodic scanning to release unused
+    non-topmost segments.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.
+
+  Extension support
+    A void* pointer and a size_t field that can be used to help implement
+    extensions to this malloc.

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probablistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;
+  void *our_os_pools[MAX_POOL_ENTRIES];
+
+  void *osMoreCore(int size)
+  {
+    void *ptr = 0;
+    static void *sbrk_top = 0;
+
+    if (size > 0)
+    {
+      if (size < MINIMUM_MORECORE_SIZE)
+	 size = MINIMUM_MORECORE_SIZE;
+      if (CurrentExecutionLevel() == kTaskLevel)
+	 ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
+      if (ptr == 0)
+      {
+	return (void *) MFAIL;
+      }
+      // save ptrs so they can be freed during cleanup
+      our_os_pools[next_os_pool] = ptr;
+      next_os_pool++;

+      * Use trees for large bins
+      * Support mspaces
+      * Use segments to unify sbrk-based and mmap-based system allocation,
+	removing need for emulation on most platforms without sbrk.
+      * Default safety checks
+      * Optional footer checks. Thanks to William Robertson for the idea.
+      * Internal code refactoring

+	and Anonymous.
+      * Allow override of MALLOC_ALIGNMENT (Thanks to Ruud Waij for
+	helping test this.)

+
+    V2.6.6 Sun Dec  5 07:42:19 1999  Doug Lea  (dl at gee)
+      * return null for negative arguments
+      * Added Several WIN32 cleanups from Martin C. Fong <mcfong at yahoo.com>
+	 * Add 'LACKS_SYS_PARAM_H' for those systems without 'sys/param.h'
+	  (e.g. WIN32 platforms)
+	 * Cleanup header file inclusion for WIN32 platforms
+	 * Cleanup code to avoid Microsoft Visual C++ compiler complaints

+	   memory allocation routines
+	 * Set 'malloc_getpagesize' for WIN32 platforms (needs more work)
+	 * Use 'assert' rather than 'ASSERT' in WIN32 code to conform to
+	   usage of 'assert' in non-WIN32 code
+	 * Improve WIN32 'sbrk()' emulation's 'findRegion()' routine to
+	   avoid infinite loop
+      * Always call 'fREe()' rather than 'free()'
+
+    V2.6.5 Wed Jun 17 15:57:31 1998  Doug Lea  (dl at gee)
+      * Fixed ordering problem with boundary-stamping
+
+    V2.6.3 Sun May 19 08:17:58 1996  Doug Lea  (dl at gee)
+      * Added pvalloc, as recommended by H.J. Liu
+      * Added 64bit pointer support mainly from Wolfram Gloger
+      * Added anonymously donated WIN32 sbrk emulation
+      * Malloc, calloc, getpagesize: add optimizations from Raymond Nijssen
+      * malloc_extend_top: fix mask error that caused wastage after
+	foreign sbrks
+      * Add linux mremap support code from HJ Liu
+
+    V2.6.2 Tue Dec  5 06:52:55 1995  Doug Lea  (dl at gee)
+      * Integrated most documentation with the code.
+      * Add support for mmap, with help from
+	Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Use last_remainder in more cases.
+      * Pack bins using idea from  colin@nyx10.cs.du.edu
+      * Use ordered bins instead of best-fit threshold
+      * Eliminate block-local decls to simplify tracing and debugging.
+      * Support another case of realloc via move into top
+      * Fix error occurring when initial sbrk_base not word-aligned.
+      * Rely on page size for units instead of SBRK_UNIT to
+	avoid surprises about sbrk alignment conventions.
+      * Add mallinfo, mallopt. Thanks to Raymond Nijssen
+	(raymond@es.ele.tue.nl) for the suggestion.
+      * Add `pad' argument to malloc_trim and top_pad mallopt parameter.
+      * More precautions for cases where other routines call sbrk,
+	courtesy of Wolfram Gloger (Gloger@lrz.uni-muenchen.de).
+      * Added macros etc., allowing use in linux libc from
+	H.J. Lu (hjl@gnu.ai.mit.edu)
+      * Inverted this history list
+
+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+	the work required to undo bad preallocations exceeds
+	the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since
+	no scheme using them consistently outperforms those that don't
+	given above changes.
+      * Use best fit for very large chunks to prevent some worst-cases.
+      * Added some support for debugging
+
+    V2.6.0 Sat Nov  4 07:05:23 1995  Doug Lea  (dl at gee)
+      * Removed footers when chunks are in use. Thanks to

+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin@nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+	 (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers
+	  from kpv@research.att.com
+
+    V2.5 Sat Aug  7 07:41:59 1993  Doug Lea  (dl at g.oswego.edu)
+      * removed potential for odd address access in prev_chunk
+      * removed dependency on getpagesize.h
+      * misc cosmetics and a bit more internal documentation
+      * anticosmetics: mangled names in macros to evade debugger strangeness
+      * tested on sparc, hp-700, dec-mips, rs6000
+	  with gcc & native cc (hp, dec only) allowing
+	  Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+	 structure of old version,  but most details differ.)

+small, and may grow to maturity.  (Consider building a word syllable
+by syllable.)  An object can move while it is growing.  Once it has
+been "finished" it never changes address again.  So the "top of the
+stack" is typically an immature growing object, while the rest of the
+stack is of mature, fixed size and fixed address objects.
+
+These routines grab large chunks of memory, using a function you
+supply, called `obstack_chunk_alloc'.  On occasion, they free chunks,
+by calling `obstack_chunk_free'.  You must define them and declare
+them before using any obstack macros.
+
+Each independent stack is represented by a `struct obstack'.
+Each of the obstack macros expects a pointer to such a structure
+as the first argument.
+
+One motivation for this package is the problem of growing char strings
+in symbol tables.  Unless you are "fascist pig with a read-only mind"
+--Gosper's immortal quote from HAKMEM item 154, out of context--you
+would not like to put any arbitrary upper limit on the length of your
+symbols.
+
+In practice this often means you will build many short symbols and a
+few long symbols.  At the time you are reading a symbol you don't know
+how long it is.  One traditional method is to read a symbol into a
+buffer, realloc()ating the buffer every time you try to read a symbol
+that is longer than the buffer.  This is beaut, but you still will
+want to copy the symbol from the buffer to a more permanent
+symbol-table entry say about half the time.
+
+With obstacks, you can work differently.  Use one obstack for all symbol
+names.  As you read a symbol, grow the name in the obstack gradually.
+When the name is complete, finalize it.  Then, if the symbol exists already,
+free the newly read name.
+
+The way we do this is to take a large chunk, allocating memory from
+low addresses.  When you want to build a symbol in the chunk you just
+add chars above the current "high water mark" in the chunk.  When you
+have finished adding chars, because you got to the end of the symbol,
+you know how long the chars are, and you can create a new object.
+Mostly the chars will not burst over the highest address of the chunk,
+because you would typically expect a chunk to be (say) 100 times as
+long as an average object.
+
+In case that isn't clear, when we have enough chars to make up
+the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed)
+so we just point to it where it lies.  No moving of chars is
+needed and this is the second win: potentially long strings need
+never be explicitly shuffled. Once an object is formed, it does not
+change its address during its lifetime.
+
+When the chars burst over a chunk boundary, we allocate a larger
+chunk, and then copy the partly formed object from the end of the old
+chunk to the beginning of the new larger chunk.  We then carry on
+accreting characters to the end of the object as we normally would.
+
+A special macro is provided to add a single char at a time to a
+growing object.  This allows the use of register variables, which
+break the ordinary 'growth' macro.
+
+Summary:
+	We allocate large chunks.
+	We carve out one object at a time from the current chunk.
+	Once carved, an object never moves.
+	We are free to append data of any size to the currently
+	  growing object.
+	Exactly one object is growing in an obstack at any one time.
+	You can run one obstack per control block.
+	You may have as many control blocks as you dare.
+	Because of the way we do it, you can `unwind' an obstack
+	  back to a previous state. (You may remove objects much
+	  as you would with a stack.)

+
+   The former two functions operate on STRING with length LENGTH,
+   while the later two operate on concatenation of STRING1 and STRING2
+   with lengths LENGTH1 and LENGTH2, respectively.
+
+   re_match() matches the compiled pattern in BUFP against the string,
+   starting at index START.
+
+   re_search() first tries matching at index START, then it tries to match
+   starting from index START + 1, and so on.  The last start position tried
+   is START + RANGE.  (Thus RANGE = 0 forces re_search to operate the same
+   way as re_match().)
+
+   The parameter STOP of re_{match,search}_2 specifies that no match exceeding
+   the first STOP characters of the concatenation of the strings should be
+   concerned.
+
+   If REGS is not NULL, and BUFP->no_sub is not set, the offsets of the match
+   and all groups is stroed in REGS.  (For the "_2" variants, the offsets are
+   computed relative to the concatenation, not relative to the individual
+   strings.)
+
+   On success, re_match* functions return the length of the match, re_search*
+   return the position of the start of the match.  Return value -1 means no

+The Steps of Build Git with VS2008
+
+1. You need the build environment, which contains the Git dependencies
+   to be able to compile, link and run Git with MSVC.
+
+   You can either use the binary repository:
+
+       WWW: http://repo.or.cz/w/msvcgit.git
+       Git: git clone git://repo.or.cz/msvcgit.git
+       Zip: http://repo.or.cz/w/msvcgit.git?a=snapshot;h=master;sf=zip
+
+   and call the setup_32bit_env.cmd batch script before compiling Git,
+   (see repo/package README for details), or the source repository:
+
+       WWW: http://repo.or.cz/w/gitbuild.git
+       Git: git clone git://repo.or.cz/gitbuild.git
+       Zip: (None, as it's a project with submodules)
+
+   and build the support libs as instructed in that repo/package.
+
+2. Ensure you have the msysgit environment in your path, so you have
+   GNU Make, bash and perl available.
+
+       WWW: http://repo.or.cz/w/msysgit.git
+       Git: git clone git://repo.or.cz/msysgit.git
+       Zip: http://repo.or.cz/w/msysgit.git?a=snapshot;h=master;sf=zip
+
+   This environment is also needed when you use the resulting
+   executables, since Git might need to run scripts which are part of
+   the git operations.
+
+3. Inside Git's directory run the command:
+       make common-cmds.h
+   to generate the common-cmds.h file needed to compile git.
+
+4. Then either build Git with the GNU Make Makefile in the Git projects
+   root
+       make MSVC=1
+   or generate Visual Studio solution/projects (.sln/.vcproj) with the
+   command
+       perl contrib/buildsystems/generate -g Vcproj
+   and open and build the solution with the IDE
+       devenv git.sln /useenv
+   or build with the IDE build engine directly from the command line
+       devenv git.sln /useenv /build "Release|Win32"
+   The /useenv option is required, so Visual Studio picks up the
+   environment variables for the support libraries required to build
+   Git, which you set up in step 1.
+
+Done!

+# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>

+#
+# This script allows you to see repository status in your prompt.
+#
+# To enable:
+#
+#    1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
+#    2) Add the following line to your .bashrc/.zshrc:
+#        source ~/.git-prompt.sh
+#    3a) Change your PS1 to call __git_ps1 as
+#        command-substitution:
+#        Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
+#        ZSH:  setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
+#        the optional argument will be used as format string.
+#    3b) Alternatively, for a slightly faster prompt, __git_ps1 can
+#        be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
+#        with two parameters, <pre> and <post>, which are strings
+#        you would put in $PS1 before and after the status string
+#        generated by the git-prompt machinery.  e.g.
+#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
+#          will show username, at-sign, host, colon, cwd, then
+#          various status string, followed by dollar and SP, as
+#          your prompt.
+#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
+#          will show username, pipe, then various status string,
+#          followed by colon, cwd, dollar and SP, as your prompt.
+#        Optionally, you can supply a third argument with a printf
+#        format string to finetune the output of the branch status
+#
+# The repository status will be displayed only if you are currently in a
+# git repository. The %s token is the placeholder for the shown status.
+#
+# The prompt status always includes the current branch name.
+#
+# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
+# unstaged (*) and staged (+) changes will be shown next to the branch
+# name.  You can configure this per-repository with the
+# bash.showDirtyState variable, which defaults to true once
+# GIT_PS1_SHOWDIRTYSTATE is enabled.
+#
+# You can also see if currently something is stashed, by setting
+# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
+# then a '$' will be shown next to the branch name.
+#
+# If you would like to see if there're untracked files, then you can set
+# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
+# files, then a '%' will be shown next to the branch name.  You can
+# configure this per-repository with the bash.showUntrackedFiles
+# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
+# enabled.
+#
+# If you would like to see the difference between HEAD and its upstream,
+# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
+# indicates you are ahead, "<>" indicates you have diverged and "="
+# indicates that there is no difference. You can further control
+# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
+# of values:
+#
+#     verbose       show number of commits ahead/behind (+/-) upstream
+#     name          if verbose, then also show the upstream abbrev name
+#     legacy        don't use the '--count' option available in recent
+#                   versions of git-rev-list
+#     git           always compare HEAD to @{upstream}
+#     svn           always compare HEAD to your SVN upstream
+#
+# You can change the separator between the branch name and the above
+# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
+# is SP.
+#
+# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
+# find one, or @{upstream} otherwise.  Once you have set
+# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
+# setting the bash.showUpstream config variable.
+#
+# If you would like to see more information about the identity of
+# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
+# to one of these values:
+#
+#     contains      relative to newer annotated tag (v1.6.3.2~35)
+#     branch        relative to newer tag or branch (master~4)
+#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
+#     default       exactly matching tag
+#
+# If you would like a colored hint about the current dirty state, set
+# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
+# the colored output of "git status -sb" and are available only when
+# using __git_ps1 for PROMPT_COMMAND or precmd.
+#
+# If you would like __git_ps1 to do nothing in the case when the current
+# directory is set up to be ignored by git, then set
+# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
+# repository level by setting bash.hideIfPwdIgnored to "false".

+===============
+
+NAME
+----
+git-contacts - List people who might be interested in a set of changes
+
+
+SYNOPSIS
+--------
+[verse]
+'git contacts' (<patch>|<range>|<rev>)...
+
+
+DESCRIPTION
+-----------
+
+Given a set of changes, specified as patch files or revisions, determine people
+who might be interested in those changes.  This is done by consulting the
+history of each patch or revision hunk to find people mentioned by commits
+which touched the lines of files under consideration.
+
+Input consists of one or more patch files or revision arguments.  A revision
+argument can be a range or a single `<rev>` which is interpreted as
+`<rev>..HEAD`, thus the same revision arguments are accepted as for
+linkgit:git-format-patch[1]. Patch files and revision arguments can be combined
+in the same invocation.
+
+This command can be useful for determining the list of people with whom to
+discuss proposed changes, or for finding the list of recipients to Cc: when
+submitting a patch series via `git send-email`. For the latter case, `git
+contacts` can be used as the argument to `git send-email`'s `--cc-cmd` option.
+
+
+DISCUSSION
+----------
+
+`git blame` is invoked for each hunk in a patch file or revision.  For each
+commit mentioned by `git blame`, the commit message is consulted for people who
+authored, reviewed, signed, acknowledged, or were Cc:'d.  Once the list of
+participants is known, each person's relevance is computed by considering how
+many commits mentioned that person compared with the total number of commits
+under consideration.  The final output consists only of participants who exceed
+a minimum threshold of participation.
+
+
+OUTPUT
+------
+
+For each person of interest, a single line is output, terminated by a newline.
+If the person's name is known, ``Name $$<user@host>$$'' is printed; otherwise
+only ``$$<user@host>$$'' is printed.
+
+
+EXAMPLES
+--------
+
+* Consult patch files:
++
+------------
+$ git contacts feature/*.patch
+------------
+
+* Revision range:
++
+------------
+$ git contacts R1..R2

+LIMITATIONS
+-----------
+
+Several conditions controlling a person's significance are currently
+hard-coded, such as minimum participation level (10%), blame date-limiting (5
+years), and `-C` level for detecting moved and copied lines (a single `-C`). In
+the future, these conditions may become configurable.

+  -f|--file AUTHFILE : specify netrc-style files.  Files with the .gpg extension
+                       will be decrypted by GPG before parsing.  Multiple -f
+                       arguments are OK.  They are processed in order, and the
+                       first matching entry found is returned via the credential
+                       helper protocol (see below).
+
+                       When no -f option is given, .authinfo.gpg, .netrc.gpg,
+		       .authinfo, and .netrc files in your home directory are used
+		       in this order.
+
+  -k|--insecure      : ignore bad file ownership or permissions
+
+  -d|--debug         : turn on debugging (developer info)
+
+  -v|--verbose       : be more verbose (show files and information found)
+
+To enable this credential helper:
+
+  git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'
+
+(Note that Git will prepend "git-credential-" to the helper name and look for it
+in the path.)
+
+...and if you want lots of debugging info:
+
+  git config credential.helper '$shortname -f AUTHFILE -d'
+
+...or to see the files opened and data found:
+
+  git config credential.helper '$shortname -f AUTHFILE -v'
+
+Only "get" mode is supported by this credential helper.  It opens every AUTHFILE
+and looks for the first entry that matches the requested search criteria:
+
+ 'port|protocol':
+   The protocol that will be used (e.g., https). (protocol=X)
+
+ 'machine|host':
+   The remote hostname for a network credential. (host=X)
+
+ 'path':
+   The path with which the credential will be used. (path=X)
+
+ 'login|user|username':
+   The credential’s username, if we already have one. (username=X)
+
+Thus, when we get this query on STDIN:
+
+host=github.com
+protocol=https
+username=tzz
+
+this credential helper will look for the first entry in every AUTHFILE that
+matches
+
+machine github.com port https login tzz
+
+OR
+
+machine github.com protocol https login tzz
+
+OR... etc. acceptable tokens as listed above.  Any unknown tokens are
+simply ignored.
+
+Then, the helper will print out whatever tokens it got from the entry, including
+"password" tokens, mapping back to Git's helper protocol; e.g. "port" is mapped
+back to "protocol".  Any redundant entry tokens (part of the original query) are
+skipped.
+
+Again, note that only the first matching entry from all the AUTHFILEs, processed
+in the sequence given on the command line, is used.
+
+Netrc/authinfo tokens can be quoted as 'STRING' or "STRING".
+
+No caching is performed by this credential helper.

+diff-highlight
+==============
+
+Line oriented diffs are great for reviewing code, because for most
+hunks, you want to see the old and the new segments of code next to each
+other. Sometimes, though, when an old line and a new line are very
+similar, it's hard to immediately see the difference.
+
+You can use "--color-words" to highlight only the changed portions of
+lines. However, this can often be hard to read for code, as it loses
+the line structure, and you end up with oddly formatted bits.
+
+Instead, this script post-processes the line-oriented diff, finds pairs
+of lines, and highlights the differing segments.  It's currently very
+simple and stupid about doing these tasks. In particular:
+
+  1. It will only highlight hunks in which the number of removed and
+     added lines is the same, and it will pair lines within the hunk by
+     position (so the first removed line is compared to the first added
+     line, and so forth). This is simple and tends to work well in
+     practice. More complex changes don't highlight well, so we tend to
+     exclude them due to the "same number of removed and added lines"
+     restriction. Or even if we do try to highlight them, they end up
+     not highlighting because of our "don't highlight if the whole line
+     would be highlighted" rule.
+
+  2. It will find the common prefix and suffix of two lines, and
+     consider everything in the middle to be "different". It could
+     instead do a real diff of the characters between the two lines and
+     find common subsequences. However, the point of the highlight is to
+     call attention to a certain area. Even if some small subset of the
+     highlighted area actually didn't change, that's OK. In practice it
+     ends up being more readable to just have a single blob on the line
+     showing the interesting bit.
+
+The goal of the script is therefore not to be exact about highlighting
+changes, but to call attention to areas of interest without being
+visually distracting.  Non-diff lines and existing diff coloration is
+preserved; the intent is that the output should look exactly the same as
+the input, except for the occasional highlight.
+
+Use
+---
+
+You can try out the diff-highlight program with:
+
+---------------------------------------------
+git log -p --color | /path/to/diff-highlight
+---------------------------------------------
+
+If you want to use it all the time, drop it in your $PATH and put the
+following in your git configuration:
+
+---------------------------------------------
+[pager]
+	log = diff-highlight | less
+	show = diff-highlight | less
+	diff = diff-highlight | less
+---------------------------------------------
+
+
+Color Config
+------------
+
+You can configure the highlight colors and attributes using git's
+config. The colors for "old" and "new" lines can be specified
+independently. There are two "modes" of configuration:
+
+  1. You can specify a "highlight" color and a matching "reset" color.
+     This will retain any existing colors in the diff, and apply the
+     "highlight" and "reset" colors before and after the highlighted
+     portion.
+
+  2. You can specify a "normal" color and a "highlight" color. In this
+     case, existing colors are dropped from that line. The non-highlighted
+     bits of the line get the "normal" color, and the highlights get the
+     "highlight" color.
+
+If no "new" colors are specified, they default to the "old" colors. If
+no "old" colors are specified, the default is to reverse the foreground
+and background for highlighted portions.
+
+Examples:
+
+---------------------------------------------
+# Underline highlighted portions
+[color "diff-highlight"]
+oldHighlight = ul
+oldReset = noul
+---------------------------------------------
+
+---------------------------------------------
+# Varying background intensities
+[color "diff-highlight"]
+oldNormal = "black #f8cbcb"
+oldHighlight = "black #ffaaaa"
+newNormal = "black #cbeecb"
+newHighlight = "black #aaffaa"
+---------------------------------------------
+
+
+Bugs
+----
+
+Because diff-highlight relies on heuristics to guess which parts of
+changes are important, there are some cases where the highlighting is
+more distracting than useful. Fortunately, these cases are rare in
+practice, and when they do occur, the worst case is simply a little
+extra highlighting. This section documents some cases known to be
+sub-optimal, in case somebody feels like working on improving the
+heuristics.
+
+1. Two changes on the same line get highlighted in a blob. For example,
+   highlighting:
+
+----------------------------------------------
+-foo(buf, size);
++foo(obj->buf, obj->size);
+----------------------------------------------
+
+   yields (where the inside of "+{}" would be highlighted):
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->buf, obj->}size);
+----------------------------------------------
+
+   whereas a more semantically meaningful output would be:
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->}buf, +{obj->}size);
+----------------------------------------------
+
+   Note that doing this right would probably involve a set of
+   content-specific boundary patterns, similar to word-diff. Otherwise
+   you get junk like:
+
+-----------------------------------------------------
+-this line has some -{i}nt-{ere}sti-{ng} text on it
++this line has some +{fa}nt+{a}sti+{c} text on it
+-----------------------------------------------------
+
+   which is less readable than the current output.
+
+2. The multi-line matching assumes that lines in the pre- and post-image
+   match by position. This is often the case, but can be fooled when a
+   line is removed from the top and a new one added at the bottom (or
+   vice versa). Unless the lines in the middle are also changed, diffs
+   will show this as two hunks, and it will not get highlighted at all
+   (which is good). But if the lines in the middle are changed, the
+   highlighting can be misleading. Here's a pathological case:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two 2
++three 3
++four 4
++five 5
+-----------------------------------------------------
+
+   which gets highlighted as:
+
+-----------------------------------------------------
+-one
+-t-{wo}
+-three
+-f-{our}
++two 2
++t+{hree 3}
++four 4
++f+{ive 5}
+-----------------------------------------------------
+
+   because it matches "two" to "three 3", and so forth. It would be
+   nicer as:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two +{2}
++three +{3}
++four +{4}
++five 5
+-----------------------------------------------------
+
+   which would probably involve pre-matching the lines into pairs
+   according to some heuristic.

+This directory contains various modules for Emacs support.
+
+To make the modules available to Emacs, you should add this directory
+to your load-path, and then require the modules you want. This can be
+done by adding to your .emacs something like this:
+
+  (add-to-list 'load-path ".../git/contrib/emacs")
+  (require 'git)
+  (require 'git-blame)
+
+
+The following modules are available:
+
+* git.el:
+
+  Status manager that displays the state of all the files of the
+  project, and provides easy access to the most frequently used git
+  commands. The user interface is as far as possible compatible with
+  the pcl-cvs mode. It can be started with `M-x git-status'.
+
+* git-blame.el:
+
+  Emacs implementation of incremental git-blame.  When you turn it on
+  while viewing a file, the editor buffer will be updated by setting
+  the background of individual lines to a color that reflects which
+  commit it comes from.  And when you move around the buffer, a
+  one-line summary will be shown in the echo area.
+
+* vc-git.el:
+
+  This file used to contain the VC-mode backend for git, but it is no
+  longer distributed with git. It is now maintained as part of Emacs
+  and included in standard Emacs distributions starting from version
+  22.2.
+
+  If you have an earlier Emacs version, upgrading to Emacs 22 is
+  recommended, since the VC mode in older Emacs is not generic enough
+  to be able to support git in a reasonable manner, and no attempt has
+  been made to backport vc-git.el.

-;;
-;; To install: put this file on the load-path and add GIT to the list

-;; TODO
-;;  - changelog generation

+
+
+DESCRIPTION
+-----------
+Imports a SVN repository into git. It will either create a new
+repository, or incrementally import into an existing one.
+
+SVN access is done by the SVN::Perl module.
+
+git-svnimport assumes that SVN repositories are organized into one
+"trunk" directory where the main development happens, "branches/FOO"
+directories for branches, and "/tags/FOO" directories for tags.
+Other subdirectories are ignored.
+
+git-svnimport creates a file ".git/svn2git", which is required for
+incremental SVN imports.
+
+OPTIONS
+-------
+-C <target-dir>::
+        The GIT repository to import to.  If the directory doesn't
+        exist, it will be created.  Default is the current directory.
+
+-s <start_rev>::
+        Start importing at this SVN change number. The  default is 1.
++
+When importing incrementally, you might need to edit the .git/svn2git file.
+
+-i::
+	Import-only: don't perform a checkout after importing.  This option
+	ensures the working directory and index remain untouched and will
+	not create them if they do not exist.
+
+-T <trunk_subdir>::
+	Name the SVN trunk. Default "trunk".
+
+-t <tag_subdir>::
+	Name the SVN subdirectory for tags. Default "tags".
+
+-b <branch_subdir>::
+	Name the SVN subdirectory for branches. Default "branches".
+
+-o <branch-for-HEAD>::
+	The 'trunk' branch from SVN is imported to the 'origin' branch within
+	the git repository. Use this option if you want to import into a
+	different branch.
+
+-r::
+	Prepend 'rX: ' to commit messages, where X is the imported
+	subversion revision.
+
+-u::
+	Replace underscores in tag names with periods.
+
+-I <ignorefile_name>::
+	Import the svn:ignore directory property to files with this
+	name in each directory. (The Subversion and GIT ignore
+	syntaxes are similar enough that using the Subversion patterns
+	directly with "-I .gitignore" will almost always just work.)
+
+-A <author_file>::
+	Read a file with lines on the form
++
+------
+	username = User's Full Name <email@addr.es>
+
+------
++
+and use "User's Full Name <email@addr.es>" as the GIT
+author and committer for Subversion commits made by
+"username". If encountering a commit made by a user not in the
+list, abort.
++
+For convenience, this data is saved to $GIT_DIR/svn-authors
+each time the -A option is provided, and read from that same
+file each time git-svnimport is run with an existing GIT
+repository without -A.
+
+-m::
+	Attempt to detect merges based on the commit message. This option
+	will enable default regexes that try to capture the name source
+	branch name from the commit message.
+
+-M <regex>::
+	Attempt to detect merges based on the commit message with a custom
+	regex. It can be used with -m to also see the default regexes.
+	You must escape forward slashes.
+
+-l <max_rev>::
+	Specify a maximum revision number to pull.
++
+Formerly, this option controlled how many revisions to pull,
+due to SVN memory leaks. (These have been worked around.)
+
+-R <repack_each_revs>::
+	Specify how often git repository should be repacked.
++
+The default value is 1000. git-svnimport will do imports in chunks of 1000
+revisions, after each chunk the git repository will be repacked. To disable
+this behavior specify some large value here which is greater than the number of
+revisions to import.
+
+-P <path_from_trunk>::
+	Partial import of the SVN tree.
++
+By default, the whole tree on the SVN trunk (/trunk) is imported.
+'-P my/proj' will import starting only from '/trunk/my/proj'.
+This option is useful when you want to import one project from a
+svn repo which hosts multiple projects under the same trunk.
+
+-v::
+	Verbosity: let 'svnimport' report what it is doing.
+
+-d::
+	Use direct HTTP requests if possible. The "<path>" argument is used
+	only for retrieving the SVN logs; the path to the contents is
+	included in the SVN log.
+
+-D::
+	Use direct HTTP requests if possible. The "<path>" argument is used
+	for retrieving the logs, as well as for the contents.
++
+There's no safe way to automatically find out which of these options to
+use, so you need to try both. Usually, the one that's wrong will die
+with a 40x error pretty quickly.
+
+<SVN_repository_URL>::
+	The URL of the SVN module you want to import. For local
+	repositories, use "file:///absolute/path".
++
+If you're using the "-d" or "-D" option, this is the URL of the SVN
+repository itself; it usually ends in "/svn".
+
+<path>::
+	The path to the module you want to check out.
+
+-h::
+	Print a short usage message and exit.
+
+OUTPUT
+------
+If '-v' is specified, the script reports what it is doing.
+
+Otherwise, success is indicated the Unix way, i.e. by simply exiting with
+a zero exit status.

+=head1 NAME
+
+import-directories - Import bits and pieces to Git.
+
+=head1 SYNOPSIS
+
+B<import-directories.perl> F<configfile> F<outputfile>
+
+=head1 DESCRIPTION
+
+Script to import arbitrary projects version controlled by the "copy the
+source directory to a new location and edit it there"-version controlled
+projects into version control. Handles projects with arbitrary branching
+and version trees, taking a file describing the inputs and generating a
+file compatible with the L<git-fast-import(1)> format.
+
+=head1 CONFIGURATION FILE
+
+=head2 Format
+
+The configuration file is based on the standard I<.ini> format.
+
+ ; Comments start with semi-colons
+ [section]
+ key=value
+
+Please see below for information on how to escape special characters.
+
+=head2 Global configuration
+
+Global configuration is done in the B<[config]> section, which should be
+the first section in the file. Configuration can be changed by
+repeating configuration sections later on.
+
+ [config]
+ ; configure conversion of CRLFs. "convert" means that all CRLFs
+ ; should be converted into LFs (suitable for the core.autocrlf
+ ; setting set to true in Git). "none" means that all data is
+ ; treated as binary.
+ crlf=convert
+
+=head2 Revision configuration
+
+Each revision that is to be imported is described in three
+sections. Revisions should be defined in topological order, so
+that a revision's parent has always been defined when a new revision
+is introduced. All the sections for one revision must be defined
+before defining the next revision.
+
+Each revision is assigned a unique numerical identifier. The
+numbers do not need to be consecutive, nor monotonically
+increasing.
+
+For instance, if your configuration file contains only the two
+revisions 4711 and 42, where 4711 is the initial commit, the
+only requirement is that 4711 is completely defined before 42.

+=pod
+
+=head3 Revision description section
+
+A section whose section name is just an integer gives meta-data
+about the revision.
+
+ [3]
+ ; author sets the author of the revisions
+ author=Peter Krefting <peter@softwolves.pp.se>
+ ; branch sets the branch that the revision should be committed to
+ branch=master
+ ; parent describes the revision that is the parent of this commit
+ ; (optional)
+ parent=1
+ ; merges describes a revision that is merged into this commit
+ ; (optional; can be repeated)
+ merges=2
+ ; selects one file to take the timestamp from
+ ; (optional; if unspecified, the most recent file from the .files
+ ;  section is used)
+ timestamp=3/source.c
+
+=head3 Revision contents section
+
+A section whose section name is an integer followed by B<.files>
+describe all the files included in this revision. If a file that
+was available previously is not included in this revision, it will
+be removed.
+
+If an on-disk revision is incomplete, you can point to files from
+a previous revision. There are no restrictions on where the source
+files are located, nor on their names.
+
+ [3.files]
+ ; the key is the path inside the repository, the value is the path
+ ; as seen from the importer script.
+ source.c=ver-3.00/source.c
+ source.h=ver-2.99/source.h
+ readme.txt=ver-3.00/introduction to the project.txt
+
+File names are treated as byte strings (but please see below on
+quoting rules), and should be stored in the configuration file in
+the encoding that should be used in the generated repository.
+
+=head3 Revision commit message section
+
+A section whose section name is an integer followed by B<.message>
+gives the commit message. This section is read verbatim, up until
+the beginning of the next section. As such, a commit message may not
+contain a line that begins with an opening square bracket ("[") and
+ends with a closing square bracket ("]"), unless they are surrounded
+by whitespace or other characters.
+
+ [3.message]
+ Implement foobar.
+ ; trailing blank lines are ignored.

+
+Key and value strings may be enclosed in quotes, in which case
+whitespace inside the quotes is preserved. Additionally, an equal
+sign may be included in the key by preceding it with a backslash.
+For example:
+
+ "key1 "=value1
+ key2=" value2"
+ key\=3=value3
+ key4=value=4
+ "key5""=value5
+
+Here the first key is "key1 " (note the trailing white-space) and the
+second value is " value2" (note the leading white-space). The third
+key contains an equal sign "key=3" and so does the fourth value, which
+does not need to be escaped. The fifth key contains a trailing quote,
+which does not need to be escaped since it is inside a surrounding
+quote.
+

+git-jump
+========
+
+Git-jump is a script for helping you jump to "interesting" parts of your
+project in your editor. It works by outputting a set of interesting
+spots in the "quickfix" format, which editors like vim can use as a
+queue of places to visit (this feature is usually used to jump to errors
+produced by a compiler). For example, given a diff like this:
+
+------------------------------------
+diff --git a/foo.c b/foo.c
+index a655540..5a59044 100644
+--- a/foo.c
++++ b/foo.c
+@@ -1,3 +1,3 @@
+ int main(void) {
+-  printf("hello word!\n");
++  printf("hello world!\n");
+ }
+-----------------------------------
+
+git-jump will feed this to the editor:
+
+-----------------------------------
+foo.c:2: printf("hello word!\n");
+-----------------------------------
+
+Obviously this trivial case isn't that interesting; you could just open
+`foo.c` yourself. But when you have many changes scattered across a
+project, you can use the editor's support to "jump" from point to point.
+
+Git-jump can generate three types of interesting lists:
+
+  1. The beginning of any diff hunks.
+
+  2. The beginning of any merge conflict markers.
+
+  3. Any grep matches.
+
+
+Using git-jump
+--------------
+
+To use it, just drop git-jump in your PATH, and then invoke it like
+this:
+
+--------------------------------------------------
+# jump to changes not yet staged for commit
+git jump diff
+
+# jump to changes that are staged for commit; you can give

+git jump diff --cached
+
+# jump to merge conflicts
+git jump merge

+--------------------------------------------------
+
+
+Related Programs
+----------------
+
+You can accomplish some of the same things with individual tools. For
+example, you can use `git mergetool` to start vimdiff on each unmerged
+file. `git jump merge` is for the vim-wielding luddite who just wants to
+jump straight to the conflict text with no fanfare.
+
+As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
+which does something similar to `git jump grep`. However, it is limited
+to positioning the cursor to the correct line in only the first file,
+leaving you to locate subsequent hits in that file or other files using
+the editor or pager. By contrast, git-jump provides the editor with a
+complete list of files and line numbers for each match.
+
+
+Limitations
+-----------
+
+This scripts was written and tested with vim. Given that the quickfix
+format is the same as what gcc produces, I expect emacs users have a
+similar feature for iterating through the list, but I know nothing about
+how to activate it.
+
+The shell snippets to generate the quickfix lines will almost certainly
+choke on filenames with exotic characters (like newlines).

+Release 1.1.1 (bugfix-only release)
+===================================
+
+* The SMTP mailer was not working with Python 2.4.
+
+Release 1.1.0
+=============
+
+* When a single commit is pushed, omit the reference changed email.
+  Set multimailhook.combineWhenSingleCommit to false to disable this
+  new feature.
+
+* In gitolite environments, the pusher's email address can be used as
+  the From address by creating a specially formatted comment block in
+  gitolite.conf (see multimailhook.from in README).
+
+* Support for SMTP authentication and SSL/TLS encryption was added,
+  see smtpUser, smtpPass, smtpEncryption in README.
+
+* A new option scanCommitForCc was added to allow git-multimail to
+  search the commit message for 'Cc: ...' lines, and add the
+  corresponding emails in Cc.
+
+* If $USER is not set, use the variable $USERNAME. This is needed on
+  Windows platform to recognize the pusher.
+
+* The emailPrefix variable can now be set to an empty string to remove
+  the prefix.
+
+* A short tutorial was added in doc/gitolite.rst to set up
+  git-multimail with gitolite.
+
+* The post-receive file was renamed to post-receive.example. It has
+  always been an example (the standard way to call git-multimail is to
+  call git_multimail.py), but it was unclear to many users.
+
+* A new refchangeShowGraph option was added to make it possible to
+  include both a graph and a log in the summary emails.  The options
+  to control the graph formatting can be set via the new graphOpts
+  option.
+
+* New option --force-send was added to disable new commit detection
+  for update hook. One use-case is to run git_multimail.py after
+  running "git fetch" to send emails about commits that have just been
+  fetched (the detection of new commits was unreliable in this mode).
+
+* The testing infrastructure was considerably improved (continuous
+  integration with travis-ci, automatic check of PEP8 and RST syntax,
+  many improvements to the test scripts).
+
+This version has been tested with Python 2.4 to 2.7, and Git 1.7.1 to
+2.4.
+
+Release 1.0.0
+=============
+
+* Fix encoding of non-ASCII email addresses in email headers.
+
+* Fix backwards-compatibility bugs for older Python 2.x versions.
+
+* Fix a backwards-compatibility bug for Git 1.7.1.
+
+* Add an option commitDiffOpts to customize logs for revisions.
+
+* Pass "-oi" to sendmail by default to prevent premature termination
+  on a line containing only ".".
+
+* Stagger email "Date:" values in an attempt to help mail clients
+  thread the emails in the right order.
+
+* If a mailing list setting is missing, just skip sending the
+  corresponding email (with a warning) instead of failing.
+
+* Add a X-Git-Host header that can be used for email filtering.
+
+* Allow the sender's fully-qualified domain name to be configured.
+
+* Minor documentation improvements.
+
+* Add this CHANGES file.
+
+
+Release 0.9.0
+=============
+
+* Initial release.

+git-multimail Version 1.1.1
+===========================
+
+.. image:: https://travis-ci.org/git-multimail/git-multimail.svg?branch=master
+    :target: https://travis-ci.org/git-multimail/git-multimail
+
+git-multimail is a tool for sending notification emails on pushes to a
+Git repository.  It includes a Python module called git_multimail.py,
+which can either be used as a hook script directly or can be imported
+as a Python module into another script.
+
+git-multimail is derived from the Git project's old
+contrib/hooks/post-receive-email, and is mostly compatible with that
+script.  See README.migrate-from-post-receive-email for details about
+the differences and for how to migrate from post-receive-email to
+git-multimail.
+
+git-multimail, like the rest of the Git project, is licensed under
+GPLv2 (see the COPYING file for details).
+
+Please note: although, as a convenience, git-multimail may be
+distributed along with the main Git project, development of
+git-multimail takes place in its own, separate project.  See section
+"Getting involved" below for more information.
+
+
+By default, for each push received by the repository, git-multimail:
+
+1. Outputs one email summarizing each reference that was changed.
+   These "reference change" (called "refchange" below) emails describe
+   the nature of the change (e.g., was the reference created, deleted,
+   fast-forwarded, etc.) and include a one-line summary of each commit
+   that was added to the reference.
+
+2. Outputs one email for each new commit that was introduced by the
+   reference change.  These "commit" emails include a list of the
+   files changed by the commit, followed by the diffs of files
+   modified by the commit.  The commit emails are threaded to the
+   corresponding reference change email via "In-Reply-To".  This style
+   (similar to the "git format-patch" style used on the Git mailing
+   list) makes it easy to scan through the emails, jump to patches
+   that need further attention, and write comments about specific
+   commits.  Commits are handled in reverse topological order (i.e.,
+   parents shown before children).  For example::
+
+     [git] branch master updated
+     + [git] 01/08: doc: fix xref link from api docs to manual pages
+     + [git] 02/08: api-credentials.txt: show the big picture first
+     + [git] 03/08: api-credentials.txt: mention credential.helper explicitly
+     + [git] 04/08: api-credentials.txt: add "see also" section
+     + [git] 05/08: t3510 (cherry-pick-sequence): add missing '&&'
+     + [git] 06/08: Merge branch 'rr/maint-t3510-cascade-fix'
+     + [git] 07/08: Merge branch 'mm/api-credentials-doc'
+     + [git] 08/08: Git 1.7.11-rc2
+
+   Each commit appears in exactly one commit email, the first time
+   that it is pushed to the repository.  If a commit is later merged
+   into another branch, then a one-line summary of the commit is
+   included in the reference change email (as usual), but no
+   additional commit email is generated.
+
+   By default, reference change emails have their "Reply-To" field set
+   to the person who pushed the change, and commit emails have their
+   "Reply-To" field set to the author of the commit.
+
+3. Output one "announce" mail for each new annotated tag, including
+   information about the tag and optionally a shortlog describing the
+   changes since the previous tag.  Such emails might be useful if you
+   use annotated tags to mark releases of your project.
+
+
+Requirements
+------------
+
+* Python 2.x, version 2.4 or later.  No non-standard Python modules
+  are required.  git-multimail does *not* currently work with Python
+  3.x.
+
+  The example scripts invoke Python using the following shebang line
+  (following PEP 394 [1]_)::
+
+      #! /usr/bin/env python2
+
+  If your system's Python2 interpreter is not in your PATH or is not
+  called ``python2``, you can change the lines accordingly.  Or you can
+  invoke the Python interpreter explicitly, for example via a tiny
+  shell script like::
+
+      #! /bin/sh
+      /usr/local/bin/python /path/to/git_multimail.py "$@"
+
+* The ``git`` command must be in your PATH.  git-multimail is known to
+  work with Git versions back to 1.7.1.  (Earlier versions have not
+  been tested; if you do so, please report your results.)
+
+* To send emails using the default configuration, a standard sendmail
+  program must be located at '/usr/sbin/sendmail' or
+  '/usr/lib/sendmail' and must be configured correctly to send emails.
+  If this is not the case, set multimailhook.sendmailCommand, or see
+  the multimailhook.mailer configuration variable below for how to
+  configure git-multimail to send emails via an SMTP server.
+
+
+Invocation
+----------
+
+git_multimail.py is designed to be used as a ``post-receive`` hook in a
+Git repository (see githooks(5)).  Link or copy it to
+$GIT_DIR/hooks/post-receive within the repository for which email
+notifications are desired.  Usually it should be installed on the
+central repository for a project, to which all commits are eventually
+pushed.
+
+For use on pre-v1.5.1 Git servers, git_multimail.py can also work as
+an ``update`` hook, taking its arguments on the command line.  To use
+this script in this manner, link or copy it to $GIT_DIR/hooks/update.
+Please note that the script is not completely reliable in this mode
+[2]_.
+
+Alternatively, git_multimail.py can be imported as a Python module
+into your own Python post-receive script.  This method is a bit more
+work, but allows the behavior of the hook to be customized using
+arbitrary Python code.  For example, you can use a custom environment
+(perhaps inheriting from GenericEnvironment or GitoliteEnvironment) to
+
+* change how the user who did the push is determined
+
+* read users' email addresses from an LDAP server or from a database
+
+* decide which users should be notified about which commits based on
+  the contents of the commits (e.g., for users who want to be notified
+  only about changes affecting particular files or subdirectories)
+
+Or you can change how emails are sent by writing your own Mailer
+class.  The ``post-receive`` script in this directory demonstrates how
+to use git_multimail.py as a Python module.  (If you make interesting
+changes of this type, please consider sharing them with the
+community.)
+
+
+Configuration
+-------------
+
+By default, git-multimail mostly takes its configuration from the
+following ``git config`` settings:
+
+multimailhook.environment
+
+    This describes the general environment of the repository.
+    Currently supported values:
+
+    * generic
+
+      the username of the pusher is read from $USER or $USERNAME and
+      the repository name is derived from the repository's path.
+
+    * gitolite
+
+      the username of the pusher is read from $GL_USER, the repository
+      name is read from $GL_REPO, and the From: header value is
+      optionally read from gitolite.conf (see multimailhook.from).
+
+      For more information about gitolite and git-multimail, read
+      doc/gitolite.rst
+
+    If neither of these environments is suitable for your setup, then
+    you can implement a Python class that inherits from Environment
+    and instantiate it via a script that looks like the example
+    post-receive script.
+
+    The environment value can be specified on the command line using
+    the --environment option.  If it is not specified on the command
+    line or by multimailhook.environment, then it defaults to
+    ``gitolite`` if the environment contains variables $GL_USER and
+    $GL_REPO; otherwise ``generic``.
+
+multimailhook.repoName
+
+    A short name of this Git repository, to be used in various places
+    in the notification email text.  The default is to use $GL_REPO
+    for gitolite repositories, or otherwise to derive this value from
+    the repository path name.
+
+multimailhook.mailingList
+
+    The list of email addresses to which notification emails should be
+    sent, as RFC 2822 email addresses separated by commas.  This
+    configuration option can be multivalued.  Leave it unset or set it
+    to the empty string to not send emails by default.  The next few
+    settings can be used to configure specific address lists for
+    specific types of notification email.
+
+multimailhook.refchangeList
+
+    The list of email addresses to which summary emails about
+    reference changes should be sent, as RFC 2822 email addresses
+    separated by commas.  This configuration option can be
+    multivalued.  The default is the value in
+    multimailhook.mailingList.  Set this value to the empty string to
+    prevent reference change emails from being sent even if
+    multimailhook.mailingList is set.
+
+multimailhook.announceList
+
+    The list of email addresses to which emails about new annotated
+    tags should be sent, as RFC 2822 email addresses separated by
+    commas.  This configuration option can be multivalued.  The
+    default is the value in multimailhook.refchangeList or
+    multimailhook.mailingList.  Set this value to the empty string to
+    prevent annotated tag announcement emails from being sent even if
+    one of the other values is set.
+
+multimailhook.commitList
+
+    The list of email addresses to which emails about individual new
+    commits should be sent, as RFC 2822 email addresses separated by
+    commas.  This configuration option can be multivalued.  The
+    default is the value in multimailhook.mailingList.  Set this value
+    to the empty string to prevent notification emails about
+    individual commits from being sent even if
+    multimailhook.mailingList is set.
+
+multimailhook.announceShortlog
+
+    If this option is set to true, then emails about changes to
+    annotated tags include a shortlog of changes since the previous
+    tag.  This can be useful if the annotated tags represent releases;
+    then the shortlog will be a kind of rough summary of what has
+    happened since the last release.  But if your tagging policy is
+    not so straightforward, then the shortlog might be confusing
+    rather than useful.  Default is false.
+
+multimailhook.refchangeShowGraph
+
+    If this option is set to true, then summary emails about reference
+    changes will additionally include:
+
+    * a graph of the added commits (if any)
+
+    * a graph of the discarded commits (if any)
+
+    The log is generated by running ``git log --graph`` with the options
+    specified in graphOpts.  The default is false.
+
+multimailhook.refchangeShowLog
+
+    If this option is set to true, then summary emails about reference
+    changes will include a detailed log of the added commits in
+    addition to the one line summary.  The log is generated by running
+    ``git log`` with the options specified in multimailhook.logOpts.
+    Default is false.
+
+multimailhook.mailer
+
+    This option changes the way emails are sent.  Accepted values are:
+
+    - sendmail (the default): use the command ``/usr/sbin/sendmail`` or
+      ``/usr/lib/sendmail`` (or sendmailCommand, if configured).  This
+      mode can be further customized via the following options:
+
+      * multimailhook.sendmailCommand
+
+        The command used by mailer ``sendmail`` to send emails.  Shell
+        quoting is allowed in the value of this setting, but remember that
+        Git requires double-quotes to be escaped; e.g.::
+
+             git config multimailhook.sendmailcommand '/usr/sbin/sendmail -oi -t -F \"Git Repo\"'
+
+        Default is '/usr/sbin/sendmail -oi -t' or
+        '/usr/lib/sendmail -oi -t' (depending on which file is
+        present and executable).
+
+      * multimailhook.envelopeSender
+
+        If set then pass this value to sendmail via the -f option to set
+        the envelope sender address.
+
+    - smtp: use Python's smtplib.  This is useful when the sendmail
+      command is not available on the system.  This mode can be
+      further customized via the following options:
+
+      * multimailhook.smtpServer
+
+        The name of the SMTP server to connect to.  The value can
+        also include a colon and a port number; e.g.,
+        ``mail.example.com:25``.  Default is 'localhost' using port 25.
+
+      * multimailhook.smtpUser
+      * multimailhook.smtpPass
+
+        Server username and password. Required if smtpEncryption is 'ssl'.
+        Note that the username and password currently need to be
+        set cleartext in the configuration file, which is not
+        recommended. If you need to use this option, be sure your
+        configuration file is read-only.
+
+      * multimailhook.envelopeSender
+
+        The sender address to be passed to the SMTP server.  If
+        unset, then the value of multimailhook.from is used.
+
+      * multimailhook.smtpServerTimeout
+
+        Timeout in seconds.
+
+      * multimailhook.smtpEncryption
+
+        Set the security type. Allowed values: none, ssl.
+        Default=none.
+
+      * multimailhook.smtpServerDebugLevel
+
+        Integer number. Set to greater than 0 to activate debugging.
+
+multimailhook.from
+
+    If set, use this value in the From: field of generated emails.  If
+    unset, the value of the From: header is determined as follows:
+
+    1. (gitolite environment only) Parse gitolite.conf, looking for a
+       block of comments that looks like this::
+
+           # BEGIN USER EMAILS
+           # username Firstname Lastname <email@example.com>
+           # END USER EMAILS
+
+       If that block exists, and there is a line between the BEGIN
+       USER EMAILS and END USER EMAILS lines where the first field
+       matches the gitolite username ($GL_USER), use the rest of the
+       line for the From: header.
+
+    2. If the user.email configuration setting is set, use its value
+       (and the value of user.name, if set).
+
+    3. Use the value of multimailhook.envelopeSender.
+
+multimailhook.administrator
+
+    The name and/or email address of the administrator of the Git
+    repository; used in FOOTER_TEMPLATE.  Default is
+    multimailhook.envelopesender if it is set; otherwise a generic
+    string is used.
+
+multimailhook.emailPrefix
+
+    All emails have this string prepended to their subjects, to aid
+    email filtering (though filtering based on the X-Git-* email
+    headers is probably more robust).  Default is the short name of
+    the repository in square brackets; e.g., ``[myrepo]``.  Set this
+    value to the empty string to suppress the email prefix.
+
+multimailhook.emailMaxLines
+
+    The maximum number of lines that should be included in the body of
+    a generated email.  If not specified, there is no limit.  Lines
+    beyond the limit are suppressed and counted, and a final line is
+    added indicating the number of suppressed lines.
+
+multimailhook.emailMaxLineLength
+
+    The maximum length of a line in the email body.  Lines longer than
+    this limit are truncated to this length with a trailing `` [...]``
+    added to indicate the missing text.  The default is 500, because
+    (a) diffs with longer lines are probably from binary files, for
+    which a diff is useless, and (b) even if a text file has such long
+    lines, the diffs are probably unreadable anyway.  To disable line
+    truncation, set this option to 0.
+
+multimailhook.maxCommitEmails
+
+    The maximum number of commit emails to send for a given change.
+    When the number of patches is larger that this value, only the
+    summary refchange email is sent.  This can avoid accidental
+    mailbombing, for example on an initial push.  To disable commit
+    emails limit, set this option to 0.  The default is 500.
+
+multimailhook.emailStrictUTF8
+
+    If this boolean option is set to `true`, then the main part of the
+    email body is forced to be valid UTF-8.  Any characters that are
+    not valid UTF-8 are converted to the Unicode replacement
+    character, U+FFFD.  The default is `true`.
+
+multimailhook.diffOpts
+
+    Options passed to ``git diff-tree`` when generating the summary
+    information for ReferenceChange emails.  Default is ``--stat
+    --summary --find-copies-harder``.  Add -p to those options to
+    include a unified diff of changes in addition to the usual summary
+    output.  Shell quoting is allowed; see multimailhook.logOpts for
+    details.
+
+multimailhook.graphOpts
+
+    Options passed to ``git log --graph`` when generating graphs for the
+    reference change summary emails (used only if refchangeShowGraph
+    is true).  The default is '--oneline --decorate'.
+
+    Shell quoting is allowed; see logOpts for details.
+
+multimailhook.logOpts
+
+    Options passed to ``git log`` to generate additional info for
+    reference change emails (used only if refchangeShowLog is set).
+    For example, adding -p will show each commit's complete diff.  The
+    default is empty.
+
+    Shell quoting is allowed; for example, a log format that contains
+    spaces can be specified using something like::
+
+      git config multimailhook.logopts '--pretty=format:"%h %aN <%aE>%n%s%n%n%b%n"'
+
+    If you want to set this by editing your configuration file
+    directly, remember that Git requires double-quotes to be escaped
+    (see git-config(1) for more information)::
+
+      [multimailhook]
+              logopts = --pretty=format:\"%h %aN <%aE>%n%s%n%n%b%n\"
+
+multimailhook.commitLogOpts
+
+    Options passed to ``git log`` to generate additional info for
+    revision change emails.  For example, adding --ignore-all-spaces
+    will suppress whitespace changes.  The default options are ``-C
+    --stat -p --cc``.  Shell quoting is allowed; see
+    multimailhook.logOpts for details.
+
+multimailhook.emailDomain
+
+    Domain name appended to the username of the person doing the push
+    to convert it into an email address
+    (via ``"%s@%s" % (username, emaildomain)``). More complicated
+    schemes can be implemented by overriding Environment and
+    overriding its get_pusher_email() method.
+
+multimailhook.replyTo
+multimailhook.replyToCommit
+multimailhook.replyToRefchange
+
+    Addresses to use in the Reply-To: field for commit emails
+    (replyToCommit) and refchange emails (replyToRefchange).
+    multimailhook.replyTo is used as default when replyToCommit or
+    replyToRefchange is not set.  The value for these variables can be
+    either:
+
+    - An email address, which will be used directly.
+
+    - The value `pusher`, in which case the pusher's address (if
+      available) will be used.  This is the default for refchange
+      emails.
+
+    - The value `author` (meaningful only for replyToCommit), in which
+      case the commit author's address will be used.  This is the
+      default for commit emails.
+
+    - The value `none`, in which case the Reply-To: field will be
+      omitted.
+
+multimailhook.quiet
+
+    Do not output the list of email recipients from the hook
+
+multimailhook.stdout
+
+    For debugging, send emails to stdout rather than to the
+    mailer.  Equivalent to the --stdout command line option
+
+multimailhook.scanCommitForCc
+
+    If this option is set to true, than recipients from lines in commit body
+    that starts with ``CC:`` will be added to CC list.
+    Default: false
+
+multimailhook.combineWhenSingleCommit
+
+    If this option is set to true and a single new commit is pushed to
+    a branch, combine the summary and commit email messages into a
+    single email.
+    Default: true
+
+
+Email filtering aids
+--------------------
+
+All emails include extra headers to enable fine tuned filtering and
+give information for debugging.  All emails include the headers
+``X-Git-Host``, ``X-Git-Repo``, ``X-Git-Refname``, and ``X-Git-Reftype``.
+ReferenceChange emails also include headers ``X-Git-Oldrev`` and ``X-Git-Newrev``;
+Revision emails also include header ``X-Git-Rev``.
+
+
+Customizing email contents
+--------------------------
+
+git-multimail mostly generates emails by expanding templates.  The
+templates can be customized.  To avoid the need to edit
+git_multimail.py directly, the preferred way to change the templates
+is to write a separate Python script that imports git_multimail.py as
+a module, then replaces the templates in place.  See the provided
+post-receive script for an example of how this is done.
+
+
+Customizing git-multimail for your environment
+----------------------------------------------
+
+git-multimail is mostly customized via an "environment" that describes
+the local environment in which Git is running.  Two types of
+environment are built in:
+
+* GenericEnvironment: a stand-alone Git repository.
+
+* GitoliteEnvironment: a Git repository that is managed by gitolite
+  [3]_.  For such repositories, the identity of the pusher is read from
+  environment variable $GL_USER, the name of the repository is read
+  from $GL_REPO (if it is not overridden by multimailhook.reponame),
+  and the From: header value is optionally read from gitolite.conf
+  (see multimailhook.from).
+
+By default, git-multimail assumes GitoliteEnvironment if $GL_USER and
+$GL_REPO are set, and otherwise assumes GenericEnvironment.
+Alternatively, you can choose one of these two environments explicitly
+by setting a ``multimailhook.environment`` config setting (which can
+have the value `generic` or `gitolite`) or by passing an --environment
+option to the script.
+
+If you need to customize the script in ways that are not supported by
+the existing environments, you can define your own environment class
+class using arbitrary Python code.  To do so, you need to import
+git_multimail.py as a Python module, as demonstrated by the example
+post-receive script.  Then implement your environment class; it should
+usually inherit from one of the existing Environment classes and
+possibly one or more of the EnvironmentMixin classes.  Then set the
+``environment`` variable to an instance of your own environment class
+and pass it to ``run_as_post_receive_hook()``.
+
+The standard environment classes, GenericEnvironment and
+GitoliteEnvironment, are in fact themselves put together out of a
+number of mixin classes, each of which handles one aspect of the
+customization.  For the finest control over your configuration, you
+can specify exactly which mixin classes your own environment class
+should inherit from, and override individual methods (or even add your
+own mixin classes) to implement entirely new behaviors.  If you
+implement any mixins that might be useful to other people, please
+consider sharing them with the community!

+git-multimail is close to, but not exactly, a plug-in replacement for
+the old Git project script contrib/hooks/post-receive-email.  This
+document describes the differences and explains how to configure
+git-multimail to get behavior closest to that of post-receive-email.
+
+If you are in a hurry
+=====================
+
+A script called migrate-mailhook-config is included with
+git-multimail.  If you run this script within a Git repository that is
+configured to use post-receive-email, it will convert the
+configuration settings into the approximate equivalent settings for
+git-multimail.  For more information, run
+
+    migrate-mailhook-config --help
+
+
+Configuration differences
+=========================
+
+* The names of the config options for git-multimail are in namespace
+  "multimailhook.*" instead of "hooks.*".  (Editorial comment:
+  post-receive-email should never have used such a generic top-level
+  namespace.)
+
+* In emails about new annotated tags, post-receive-email includes a
+  shortlog of all changes since the previous annotated tag.  To get
+  this behavior with git-multimail, you need to set
+  multimailhook.announceshortlog to true:
+
+      git config multimailhook.announceshortlog true
+
+* multimailhook.commitlist -- This is a new configuration variable.
+  Recipients listed here will receive a separate email for each new
+  commit.  However, if this variable is *not* set, it defaults to the
+  value of multimailhook.mailinglist.  Therefore, if you *don't* want
+  the members of multimailhook.mailinglist to receive one email per
+  commit, then set this value to the empty string:
+
+      git config multimailhook.commitlist ''
+
+* multimailhook.emailprefix -- If this value is not set, then the
+  subjects of generated emails are prefixed with the short name of the
+  repository enclosed in square brackets; e.g., "[myrepo]".
+  post-receive-email defaults to prefix "[SCM]" if this option is not
+  set.  So if you were using the old default and want to retain it
+  (for example, to avoid having to change your email filters), set
+  this variable explicitly to the old value:
+
+      git config multimailhook.emailprefix "[SCM]"
+
+* The "multimailhook.showrev" configuration option is not supported.
+  Its main use is obsoleted by the one-email-per-commit feature of
+  git-multimail.
+
+
+Other differences
+=================
+
+This section describes other differences in the behavior of
+git-multimail vs. post-receive-email.  For full details, please refer
+to the main README file:
+
+* One email per commit.  For each reference change, the script first
+  outputs one email summarizing the reference change (including
+  one-line summaries of the new commits), then it outputs a separate
+  email for each new commit that was introduced, including patches.
+  These one-email-per-commit emails go to the addresses listed in
+  multimailhook.commitlist.  post-receive-email sends only one email
+  for each *reference* that is changed, no matter how many commits
+  were added to the reference.
+
+* Better algorithm for detecting new commits.  post-receive-email
+  processes one reference change at a time, which causes it to fail to
+  describe new commits that were included in multiple branches.  For
+  example, if a single push adds the "*" commits in the diagram below,
+  then post-receive-email would never include the details of the two
+  commits that are common to "master" and "branch" in its
+  notifications.
+
+      o---o---o---*---*---*    <-- master
+                       \
+                        *---*  <-- branch
+
+  git-multimail analyzes all reference modifications to determine
+  which commits were not present before the change, therefore avoiding
+  that error.
+
+* In reference change emails, git-multimail tells which commits have
+  been added to the reference vs. are entirely new to the repository,
+  and which commits that have been omitted from the reference
+  vs. entirely discarded from the repository.
+
+* The environment in which Git is running can be configured via an
+  "Environment" abstraction.
+
+* Built-in support for Gitolite-managed repositories.
+
+* Instead of using full SHA1 object names in emails, git-multimail
+  mostly uses abbreviated SHA1s, plus one-line log message summaries
+  where appropriate.
+
+* In the schematic diagrams that explain non-fast-forward commits,
+  git-multimail shows the names of the branches involved.
+
+* The emails generated by git-multimail include the name of the Git
+  repository that was modified; this is convenient for recipients who
+  are monitoring multiple repositories.
+
+* git-multimail allows the email "From" addresses to be configured.
+
+* The recipients lists (multimailhook.mailinglist,
+  multimailhook.refchangelist, multimailhook.announcelist, and
+  multimailhook.commitlist) can be comma-separated values and/or
+  multivalued settings in the config file; e.g.,
+
+      [multimailhook]
+              mailinglist = mr.brown@example.com, mr.black@example.com
+              announcelist = Him <him@example.com>
+              announcelist = Jim <jim@example.com>
+              announcelist = pop@example.com
+
+  This might make it easier to maintain short recipients lists without
+  requiring full-fledged mailing list software.
+
+* By default, git-multimail sets email "Reply-To" headers to reply to
+  the pusher (for reference updates) and to the author (for commit
+  notifications).  By default, the pusher's email address is
+  constructed by appending "multimailhook.emaildomain" to the pusher's
+  username.
+
+* The generated emails contain a configurable footer.  By default, it
+  lists the name of the administrator who should be contacted to
+  unsubscribe from notification emails.
+
+* New option multimailhook.emailmaxlinelength to limit the length of
+  lines in the main part of the email body.  The default limit is 500
+  characters.
+
+* New option multimailhook.emailstrictutf8 to ensure that the main
+  part of the email body is valid UTF-8.  Invalid characters are
+  turned into the Unicode replacement character, U+FFFD.  By default
+  this option is turned on.
+
+* Written in Python.  Easier to add new features.

+"""Generate notification emails for pushes to a git repository.
+
+This hook sends emails describing changes introduced by pushes to a
+git repository.  For each reference that was changed, it emits one
+ReferenceChange email summarizing how the reference was changed,
+followed by one Revision email for each new commit that was introduced
+by the reference change.
+
+Each commit is announced in exactly one Revision email.  If the same
+commit is merged into another branch in the same or a later push, then
+the ReferenceChange email will list the commit's SHA1 and its one-line
+summary, but no new Revision email will be generated.
+
+This script is designed to be used as a "post-receive" hook in a git
+repository (see githooks(5)).  It can also be used as an "update"
+script, but this usage is not completely reliable and is deprecated.
+
+To help with debugging, this script accepts a --stdout option, which
+causes the emails to be written to standard output rather than sent
+using sendmail.
+
+See the accompanying README file for the complete documentation.

+
+    * the name of the repository to which the push occurred
+
+    * what user did the push
+
+    * what users want to be informed about various types of changes.
+
+    An Environment object is expected to have the following methods:
+
+        get_repo_shortname()
+
+            Return a short name for the repository, for display
+            purposes.
+
+        get_repo_path()
+
+            Return the absolute path to the Git repository.
+
+        get_emailprefix()
+
+            Return a string that will be prefixed to every email's
+            subject.
+
+        get_pusher()
+
+            Return the username of the person who pushed the changes.
+            This value is used in the email body to indicate who
+            pushed the change.
+
+        get_pusher_email() (may return None)
+
+            Return the email address of the person who pushed the
+            changes.  The value should be a single RFC 2822 email
+            address as a string; e.g., "Joe User <user@example.com>"
+            if available, otherwise "user@example.com".  If set, the
+            value is used as the Reply-To address for refchange
+            emails.  If it is impossible to determine the pusher's
+            email, this attribute should be set to None (in which case
+            no Reply-To header will be output).
+
+        get_sender()
+
+            Return the address to be used as the 'From' email address
+            in the email envelope.
+
+        get_fromaddr()
+
+            Return the 'From' email address used in the email 'From:'
+            headers.  (May be a full RFC 2822 email address like 'Joe
+            User <user@example.com>'.)
+
+        get_administrator()
+
+            Return the name and/or email of the repository
+            administrator.  This value is used in the footer as the
+            person to whom requests to be removed from the
+            notification list should be sent.  Ideally, it should
+            include a valid email address.
+
+        get_reply_to_refchange()
+        get_reply_to_commit()
+
+            Return the address to use in the email "Reply-To" header,
+            as a string.  These can be an RFC 2822 email address, or
+            None to omit the "Reply-To" header.
+            get_reply_to_refchange() is used for refchange emails;
+            get_reply_to_commit() is used for individual commit
+            emails.
+
+    They should also define the following attributes:
+
+        announce_show_shortlog (bool)
+
+            True iff announce emails should include a shortlog.
+
+        refchange_showgraph (bool)

+
+        refchange_showlog (bool)
+
+            True iff refchanges emails should include a detailed log.
+
+        diffopts (list of strings)
+
+            The options that should be passed to 'git diff' for the
+            summary email.  The value should be a list of strings
+            representing words to be passed to the command.
+
+        graphopts (list of strings)
+
+            Analogous to diffopts, but contains options passed to
+            'git log --graph' when generating the detailed graph for
+            a set of commits (see refchange_showgraph)
+
+        logopts (list of strings)
+
+            Analogous to diffopts, but contains options passed to
+            'git log' when generating the detailed log for a set of

+
+    It is easy to figure out what commits were added to a *branch* by
+    a Reference change:
+
+        git rev-list change.old..change.new
+
+    or removed from a *branch*:
+
+        git rev-list change.new..change.old
+
+    But it is not quite so trivial to determine which entirely new
+    commits were added to the *repository* by a push and which old
+    commits were discarded by a push.  A big part of the job of this
+    class is to figure out these things, and to make sure that new
+    commits are only detailed once even if they were added to multiple
+    references.
+
+    The first step is to determine the "other" references--those
+    unaffected by the current push.  They are computed by listing all
+    references then removing any affected by this push.  The results
+    are stored in Push._other_ref_sha1s.
+
+    The commits contained in the repository before this push were
+
+        git rev-list other1 other2 other3 ... change1.old change2.old ...
+
+    Where "changeN.old" is the old value of one of the references
+    affected by this push.
+
+    The commits contained in the repository after this push are
+
+        git rev-list other1 other2 other3 ... change1.new change2.new ...
+
+    The commits added by this push are the difference between these
+    two sets, which can be written
+
+        git rev-list \
+            ^other1 ^other2 ... \
+            ^change1.old ^change2.old ... \
+            change1.new change2.new ...
+
+    The commits removed by this push can be computed by
+
+        git rev-list \
+            ^other1 ^other2 ... \
+            ^change1.new ^change2.new ... \
+            change1.old change2.old ...
+
+    The last point is that it is possible that other pushes are
+    occurring simultaneously to this one, so reference values can
+    change at any time.  It is impossible to eliminate all race
+    conditions, but we reduce the window of time during which problems
+    can occur by translating reference names to SHA1s as soon as
+    possible and working with SHA1s thereafter (because SHA1s are

+
+"""Example post-receive hook based on git-multimail.
+
+The simplest way to use git-multimail is to use the script
+git_multimail.py directly as a post-receive hook, and to configure it
+using Git's configuration files and command-line parameters.  You can
+also write your own Python wrapper for more advanced configurability,
+using git_multimail.py as a Python module.
+
+This script is a simple example of such a post-receive hook.  It is
+intended to be customized before use; see the comments in the script
+to help you get started.
+
+Using git-multimail as a Python module as done here provides more
+flexibility.  It has the following advantages:
+
+* The tool's behavior can be customized using arbitrary Python code,
+  without having to edit git_multimail.py.
+
+* Configuration settings can be read from other sources; for example,
+  user names and email addresses could be read from LDAP or from a
+  database.  Or the settings can even be hardcoded in the importing
+  Python script, if this is preferred.
+
+This script is a very basic example of how to use git_multimail.py as
+a module.  The comments below explain some of the points at which the
+script's behavior could be changed or customized.

+#!/bin/sh
+#
+# Copyright (c) 2007 Andy Parkins
+#
+# An example hook script to mail out commit update information.
+#
+# NOTE: This script is no longer under active development.  There
+# is another script, git-multimail, which is more capable and
+# configurable and is largely backwards-compatible with this script;
+# please see "contrib/hooks/multimail/".  For instructions on how to
+# migrate from post-receive-email to git-multimail, please see
+# "README.migrate-from-post-receive-email" in that directory.
+#
+# This hook sends emails listing new revisions to the repository
+# introduced by the change being reported.  The rule is that (for
+# branch updates) each commit will appear on one email and one email
+# only.
+#
+# This hook is stored in the contrib/hooks directory.  Your distribution
+# will have put this somewhere standard.  You should make this script
+# executable then link to it in the repository you would like to use it in.
+# For example, on debian the hook is stored in
+# /usr/share/git-core/contrib/hooks/post-receive-email:
+#
+#  cd /path/to/your/repository.git
+#  ln -sf /usr/share/git-core/contrib/hooks/post-receive-email hooks/post-receive
+#
+# This hook script assumes it is enabled on the central repository of a
+# project, with all users pushing only to it and not between each other.  It
+# will still work if you don't operate in that style, but it would become
+# possible for the email to be from someone other than the person doing the
+# push.
+#
+# To help with debugging and use on pre-v1.5.1 git servers, this script will
+# also obey the interface of hooks/update, taking its arguments on the
+# command line.  Unfortunately, hooks/update is called once for each ref.
+# To avoid firing one email per ref, this script just prints its output to
+# the screen when used in this mode.  The output can then be redirected if
+# wanted.
+#
+# Config
+# ------
+# hooks.mailinglist
+#   This is the list that all pushes will go to; leave it blank to not send
+#   emails for every ref update.
+# hooks.announcelist
+#   This is the list that all pushes of annotated tags will go to.  Leave it
+#   blank to default to the mailinglist field.  The announce emails lists
+#   the short log summary of the changes since the last annotated tag.
+# hooks.envelopesender
+#   If set then the -f option is passed to sendmail to allow the envelope
+#   sender address to be set
+# hooks.emailprefix
+#   All emails have their subjects prefixed with this prefix, or "[SCM]"
+#   if emailprefix is unset, to aid filtering
+# hooks.showrev
+#   The shell command used to format each revision in the email, with
+#   "%s" replaced with the commit id.  Defaults to "git rev-list -1
+#   --pretty %s", displaying the commit id, author, date and log
+#   message.  To list full patches separated by a blank line, you
+#   could set this to "git show -C %s; echo".
+#   To list a gitweb/cgit URL *and* a full patch for each change set, use this:
+#     "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo"
+#   Be careful if "..." contains things that will be expanded by shell "eval"
+#   or printf.
+# hooks.emailmaxlines
+#   The maximum number of lines that should be included in the generated
+#   email body. If not specified, there is no limit.
+#   Lines beyond the limit are suppressed and counted, and a final
+#   line is added indicating the number of suppressed lines.
+# hooks.diffopts
+#   Alternate options for the git diff-tree invocation that shows changes.
+#   Default is "--stat --summary --find-copies-harder". Add -p to those
+#   options to include a unified diff of changes in addition to the usual
+#   summary output.
+#
+# Notes
+# -----
+# All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
+# "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and
+# give information for debugging.

+	# X is a revision pointed to by some other ref, for which we may
+	#   assume that an email has already been generated.
+	# In this case we want to issue an email containing only revisions
+	# 3, 4, and N.  Given (almost) by
+	#
+	#  git rev-list N ^O --not --all
+	#
+	# The reason for the "almost", is that the "--not --all" will take
+	# precedence over the "N", and effectively will translate to
+	#
+	#  git rev-list N ^O ^X ^N
+	#
+	# So, we need to build up the list more carefully.  git rev-parse
+	# will generate a list of revs that may be fed into git rev-list.
+	# We can get it to make the "--not --all" part and then filter out
+	# the "^N" with:
+	#
+	#  git rev-parse --not --all | grep -v N
+	#
+	# Then, using the --stdin switch to git rev-list we have effectively
+	# manufactured
+	#
+	#  git rev-list N ^O ^X
+	#
+	# This leaves a problem when someone else updates the repository
+	# while this script is running.  Their new value of the ref we're
+	# working on would be included in the "--not --all" output; and as
+	# our $newrev would be an ancestor of that commit, it would exclude
+	# all of our commits.  What we really want is to exclude the current
+	# value of $refname from the --not list, rather than N itself.  So:
+	#
+	#  git rev-parse --not --all | grep -v $(git rev-parse $refname)
+	#
+	# Get's us to something pretty safe (apart from the small time
+	# between refname being read, and git rev-parse running - for that,
+	# I give up)
+	#
+	#
+	# Next problem, consider this:
+	#   * --- B --- * --- O ($oldrev)
+	#          \
+	#           * --- X --- * --- N ($newrev)
+	#
+	# That is to say, there is no guarantee that oldrev is a strict
+	# subset of newrev (it would have required a --force, but that's
+	# allowed).  So, we can't simply say rev-list $oldrev..$newrev.
+	# Instead we find the common base of the two revs and list from
+	# there.
+	#
+	# As above, we need to take into account the presence of X; if
+	# another branch is already in the repository and points at some of
+	# the revisions that we are about to output - we don't want them.
+	# The solution is as before: git rev-parse output filtered.
+	#
+	# Finally, tags: 1 --- 2 --- O --- T --- 3 --- 4 --- N
+	#
+	# Tags pushed into the repository generate nice shortlog emails that
+	# summarise the commits between them and the previous tag.  However,
+	# those emails don't include the full commit messages that we output
+	# for a branch update.  Therefore we still want to output revisions
+	# that have been output on a tag email.
+	#
+	# Luckily, git rev-parse includes just the tool.  Instead of using
+	# "--all" we use "--branches"; this has the added benefit that
+	# "remotes/" will be ignored as well.
+
+	# List all of the revisions that were removed by this update, in a

+Invoked as: update refname old-sha1 new-sha1
+
+This script is run by git-receive-pack once for each ref that the
+client is trying to modify.  If we exit with a non-zero exit value
+then the update for that particular ref is denied, but updates for
+other refs in the same run of receive-pack may still be allowed.
+
+We are run after the objects have been uploaded, but before the
+ref is actually modified.  We take advantage of that fact when we
+look for "new" commits and tags (the new objects won't show up in
+`rev-list --all`).
+
+This script loads and parses the content of the config file
+"users/$this_user.acl" from the $acl_branch commit of $acl_git ODB.
+The acl file is a git-config style file, but uses a slightly more
+restricted syntax as the Perl parser contained within this script
+is not nearly as permissive as git-config.
+
+Example:
+
+  [user]
+    committer = John Doe <john.doe@example.com>
+    committer = John R. Doe <john.doe@example.com>
+
+  [repository "acls"]
+    allow = heads/master
+    allow = CDUR for heads/jd/
+    allow = C    for ^tags/v\\d+$
+
+For all new commit or tag objects the committer (or tagger) line
+within the object must exactly match one of the user.committer
+values listed in the acl file ("HEAD:users/$this_user.acl").
+
+For a branch to be modified an allow line within the matching
+repository section must be matched for both the refname and the
+opcode.
+
+Repository sections are matched on the basename of the repository
+(after removing the .git suffix).
+
+The opcode abbrevations are:
+
+  C: create new ref
+  D: delete existing ref
+  U: fast-forward existing ref (no commit loss)
+  R: rewind/rebase existing ref (commit loss)
+
+if no opcodes are listed before the "for" keyword then "U" (for
+fast-forward update only) is assumed as this is the most common
+usage.
+
+Refnames are matched by always assuming a prefix of "refs/".
+This hook forbids pushing or deleting anything not under "refs/".
+
+Refnames that start with ^ are Perl regular expressions, and the ^
+is kept as part of the regexp.  \\ is needed to get just one \, so
+\\d expands to \d in Perl.  The 3rd allow line above is an example.
+
+Refnames that don't start with ^ but that end with / are prefix
+matches (2nd allow line above); all other refnames are strict
+equality matches (1st allow line).
+
+Anything pushed to "heads/" (ok, really "refs/heads/") must be
+a commit.  Tags are not permitted here.
+
+Anything pushed to "tags/" (err, really "refs/tags/") must be an
+annotated tag.  Commits, blobs, trees, etc. are not permitted here.
+Annotated tag signatures aren't checked, nor are they required.
+
+The special subrepository of 'info/new-commit-check' can
+be created and used to allow users to push new commits and
+tags from another local repository to this one, even if they
+aren't the committer/tagger of those objects.  In a nut shell
+the info/new-commit-check directory is a Git repository whose
+objects/info/alternates file lists this repository and all other
+possible sources, and whose refs subdirectory contains symlinks
+to this repository's refs subdirectory, and to all other possible
+sources refs subdirectories.  Yes, this means that you cannot
+use packed-refs in those repositories as they won't be resolved
+correctly.

+USAGE: git mw preview [--remote|-r <remote name>] [--autoload|-a]
+                      [--output|-o <output filename>] [--verbose|-v]
+                      <blob> | <filename>
+
+DESCRIPTION:
+Preview is an utiliy to preview local content of a mediawiki repo as if it was
+pushed on the remote.
+
+For that, preview searches for the remote name of the current branch's
+upstream if --remote is not set. If that remote is not found or if it
+is not a mediawiki, it lists all mediawiki remotes configured and asks
+you to replay your command with the --remote option set properly.
+
+Then, it searches for a file named 'filename'. If it's not found in
+the current dir, it will assume it's a blob.
+
+The content retrieved in the file (or in the blob) will then be parsed
+by the remote mediawiki and combined with a template retrieved from
+the mediawiki.
+
+Finally, preview will save the HTML result in a file. and autoload it
+in your default web browser if the option --autoload is present.
+
+OPTIONS:
+    -r <remote name>, --remote <remote name>
+        If the remote is a mediawiki, the template and the parse engine
+        used for the preview will be those of that remote.
+        If not, a list of valid remotes will be shown.
+
+    -a, --autoload
+        Try to load the HTML output in a new tab (or new window) of your
+        default web browser.
+
+    -o <output filename>, --output <output filename>
+        Change the HTML output filename. Default filename is based on the
+        input filename with its extension replaced by '.html'.
+
+    -v, --verbose
+        Show more information on what's going on under the hood.

+Tests for Mediawiki-to-Git
+==========================
+
+Introduction
+------------
+This manual describes how to install the git-remote-mediawiki test
+environment on a machine with git installed on it.
+
+Prerequisite
+------------
+
+In order to run this test environment correctly, you will need to
+install the following packages (Debian/Ubuntu names, may need to be
+adapted for another distribution):
+
+* lighttpd
+* php5
+* php5-cgi
+* php5-cli
+* php5-curl
+* php5-sqlite
+
+Principles and Technical Choices
+--------------------------------
+
+The test environment makes it easy to install and manipulate one or
+several MediaWiki instances. To allow developers to run the testsuite
+easily, the environment does not require root privilege (except to
+install the required packages if needed). It starts a webserver
+instance on the user's account (using lighttpd greatly helps for
+that), and does not need a separate database daemon (thanks to the use
+of sqlite).
+
+Run the test environment
+------------------------
+
+Install a new wiki
+~~~~~~~~~~~~~~~~~~
+
+Once you have all the prerequisite, you need to install a MediaWiki
+instance on your machine. If you already have one, it is still
+strongly recommended to install one with the script provided. Here's
+how to work it:
+
+a. change directory to contrib/mw-to-git/t/
+b. if needed, edit test.config to choose your installation parameters
+c. run `./install-wiki.sh install`
+d. check on your favourite web browser if your wiki is correctly
+   installed.
+
+Remove an existing wiki
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Edit the file test.config to fit the wiki you want to delete, and then
+execute the command `./install-wiki.sh delete` from the
+contrib/mw-to-git/t directory.
+
+Run the existing tests
+~~~~~~~~~~~~~~~~~~~~~~
+
+The provided tests are currently in the `contrib/mw-to-git/t` directory.
+The files are all the t936[0-9]-*.sh shell scripts.
+
+a. Run all tests:
+To do so, run "make test" from the contrib/mw-to-git/ directory.
+
+b. Run a specific test:
+To run a given test <test_name>, run ./<test_name> from the
+contrib/mw-to-git/t directory.
+
+How to create new tests
+-----------------------
+
+Available functions
+~~~~~~~~~~~~~~~~~~~
+
+The test environment of git-remote-mediawiki provides some functions
+useful to test its behaviour. for more details about the functions'
+parameters, please refer to the `test-gitmw-lib.sh` and
+`test-gitmw.pl` files.
+
+** `test_check_wiki_precond`:
+Check if the tests must be skipped or not. Please use this function
+at the beginning of each new test file.
+
+** `wiki_getpage`:
+Fetch a given page from the wiki and puts its content in the
+directory in parameter.
+
+** `wiki_delete_page`:
+Delete a given page from the wiki.
+
+** `wiki_edit_page`:
+Create or modify a given page in the wiki. You can specify several
+parameters like a summary for the page edition, or add the page to a
+given category.
+See test-gitmw.pl for more details.
+
+** `wiki_getallpage`:
+Fetch all pages from the wiki into a given directory. The directory
+is created if it does not exists.
+
+** `test_diff_directories`:
+Compare the content of two directories. The content must be the same.
+Use this function to compare the content of a git directory and a wiki
+one created by wiki_getallpage.
+
+** `test_contains_N_files`:
+Check if the given directory contains a given number of file.
+
+** `wiki_page_exists`:
+Tests if a given page exists on the wiki.
+
+** `wiki_reset`:
+Reset the wiki, i.e. flush the database. Use this function at the
+beginning of each new test, except if the test re-uses the same wiki
+(and history) as the previous test.
+
+How to write a new test
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Please, follow the standards given by git. See git/t/README.
+New file should be named as t936[0-9]-*.sh.
+Be sure to reset your wiki regulary with the function `wiki_reset`.

+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+git-remote-persistent-https
+
+The git-remote-persistent-https binary speeds up SSL operations
+by running a daemon job (git-remote-persistent-https--proxy) that
+keeps a connection open to a server.
+
+
+PRE-BUILT BINARIES
+
+Darwin amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/darwin_amd64.tar.gz
+
+Linux amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/linux_amd64.tar.gz
+
+
+INSTALLING
+
+Move all of the git-remote-persistent-http* binaries to a directory
+in PATH.
+
+
+USAGE
+
+HTTPS requests can be delegated to the proxy by using the
+"persistent-https" scheme, e.g.
+
+git clone persistent-https://kernel.googlesource.com/pub/scm/git/git
+
+Likewise, .gitconfig can be updated as follows to rewrite https urls
+to use persistent-https:
+
+[url "persistent-https"]
+	insteadof = https
+[url "persistent-http"]
+	insteadof = http
+
+
+#####################################################################
+# BUILDING FROM SOURCE
+#####################################################################
+
+LOCATION
+
+The source is available in the contrib/persistent-https directory of
+the Git source repository. The Git source repository is available at
+git://git.kernel.org/pub/scm/git/git.git/
+https://kernel.googlesource.com/pub/scm/git/git
+
+
+PREREQUISITES
+
+The code is written in Go (http://golang.org/) and the Go compiler is
+required. Currently, the compiler must be built and installed from tip
+of source, in order to include a fix in the reverse http proxy:
+http://code.google.com/p/go/source/detail?r=a615b796570a2cd8591884767a7d67ede74f6648
+
+
+BUILDING
+
+Run "make" to build the binaries. See the section on
+INSTALLING above.

+#
+# This prints some full-pack statistics; currently "all sizes", "all

+#   reassemble the file from deltas.
+# * "tree sizes" are object sizes grouped into delta trees.
+# * "tree path sizes" are path sizes grouped into delta trees.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to

+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+HOW TO INSTALL git-subtree
+==========================
+
+First, build from the top source directory.
+
+Then, in contrib/subtree, run:
+
+  make
+  make install
+  make install-doc
+
+If you used configure to do the main build the git-subtree build will
+pick up those settings.  If not, you will likely have to provide a
+value for prefix:
+
+  make prefix=<some dir>
+  make prefix=<some dir> install
+  make prefix=<some dir> install-doc
+
+To run tests first copy git-subtree to the main build area so the
+newly-built git can find it:
+
+  cp git-subtree ../..
+
+Then:
+
+  make test

+NAME

+git-subtree - Merge subtrees together and split repository into subtrees
+
+
+SYNOPSIS
+--------
+[verse]
+'git subtree' add   -P <prefix> <commit>
+'git subtree' add   -P <prefix> <repository> <ref>
+'git subtree' pull  -P <prefix> <repository> <ref>
+'git subtree' push  -P <prefix> <repository> <ref>
+'git subtree' merge -P <prefix> <commit>
+'git subtree' split -P <prefix> [OPTIONS] [<commit>]
+
+
+DESCRIPTION
+-----------
+Subtrees allow subprojects to be included within a subdirectory
+of the main project, optionally including the subproject's
+entire history.
+
+For example, you could include the source code for a library
+as a subdirectory of your application.
+
+Subtrees are not to be confused with submodules, which are meant for
+the same task. Unlike submodules, subtrees do not need any special
+constructions (like .gitmodule files or gitlinks) be present in
+your repository, and do not force end-users of your
+repository to do anything special or to understand how subtrees
+work. A subtree is just a subdirectory that can be
+committed to, branched, and merged along with your project in
+any way you want.
+
+They are also not to be confused with using the subtree merge
+strategy. The main difference is that, besides merging
+the other project as a subdirectory, you can also extract the
+entire history of a subdirectory from your project and make it
+into a standalone project. Unlike the subtree merge strategy
+you can alternate back and forth between these
+two operations. If the standalone library gets updated, you can
+automatically merge the changes into your project; if you
+update the library inside your project, you can "split" the
+changes back out again and merge them back into the library
+project.
+
+For example, if a library you made for one application ends up being
+useful elsewhere, you can extract its entire history and publish
+that as its own git repository, without accidentally
+intermingling the history of your application project.
+
+[TIP]
+In order to keep your commit messages clean, we recommend that
+people split their commits between the subtrees and the main
+project as much as possible.  That is, if you make a change that
+affects both the library and the main application, commit it in
+two pieces.  That way, when you split the library commits out
+later, their descriptions will still make sense.  But if this
+isn't important to you, it's not *necessary*.  git subtree will
+simply leave out the non-library-related parts of the commit
+when it splits it out into the subproject later.
+
+
+COMMANDS
+--------
+add::
+	Create the <prefix> subtree by importing its contents
+	from the given <commit> or <repository> and remote <ref>.
+	A new commit is created	automatically, joining the imported
+	project's history with your own.  With '--squash', imports
+	only a single commit from the subproject, rather than its
+	entire history.
+
+merge::
+	Merge recent changes up to <commit> into the <prefix>
+	subtree.  As with normal 'git merge', this doesn't
+	remove your own local changes; it just merges those
+	changes into the latest <commit>.  With '--squash',
+	creates only one commit that contains all the changes,
+	rather than merging in the entire history.
++
+If you use '--squash', the merge direction doesn't always have to be
+forward; you can use this command to go back in time from v2.5 to v2.4,
+for example.  If your merge introduces a conflict, you can resolve it in
+the usual ways.
+	
+pull::
+	Exactly like 'merge', but parallels 'git pull' in that
+	it fetches the given ref from the specified remote
+	repository.
+	
+push::
+	Does a 'split' (see below) using the <prefix> supplied
+	and then does a 'git push' to push the result to the 
+	repository and ref. This can be used to push your
+	subtree to different branches of the remote repository.
+
+split::
+	Extract a new, synthetic project history from the
+	history of the <prefix> subtree.  The new history
+	includes only the commits (including merges) that
+	affected <prefix>, and each of those commits now has the
+	contents of <prefix> at the root of the project instead
+	of in a subdirectory.  Thus, the newly created history
+	is suitable for export as a separate git repository.
++
+After splitting successfully, a single commit id is printed to stdout.
+This corresponds to the HEAD of the newly created tree, which you can
+manipulate however you want.
++
+Repeated splits of exactly the same history are guaranteed to be
+identical (i.e. to produce the same commit ids).  Because of this, if
+you add new commits and then re-split, the new commits will be attached
+as commits on top of the history you generated last time, so 'git merge'
+and friends will work as expected.
++
+Note that if you use '--squash' when you merge, you should usually not
+just '--rejoin' when you split.
+
+
+OPTIONS
+-------
+-q::
+--quiet::
+	Suppress unnecessary output messages on stderr.
+
+-d::
+--debug::
+	Produce even more unnecessary output messages on stderr.
+
+-P <prefix>::
+--prefix=<prefix>::
+	Specify the path in the repository to the subtree you
+	want to manipulate.  This option is mandatory
+	for all commands.
+
+-m <message>::
+--message=<message>::
+	This option is only valid for add, merge and pull (unsure).
+	Specify <message> as the commit message for the merge commit.
+
+
+OPTIONS FOR add, merge, push, pull
+----------------------------------
+--squash::
+	This option is only valid for add, merge, and pull
+	commands.
++
+Instead of merging the entire history from the subtree project, produce
+only a single commit that contains all the differences you want to
+merge, and then merge that new commit into your project.
++
+Using this option helps to reduce log clutter. People rarely want to see
+every change that happened between v1.0 and v1.1 of the library they're
+using, since none of the interim versions were ever included in their
+application.
++
+Using '--squash' also helps avoid problems when the same subproject is
+included multiple times in the same project, or is removed and then
+re-added.  In such a case, it doesn't make sense to combine the
+histories anyway, since it's unclear which part of the history belongs
+to which subtree.
++
+Furthermore, with '--squash', you can switch back and forth between
+different versions of a subtree, rather than strictly forward.  'git
+subtree merge --squash' always adjusts the subtree to match the exactly
+specified commit, even if getting to that commit would require undoing
+some changes that were added earlier.
++
+Whether or not you use '--squash', changes made in your local repository
+remain intact and can be later split and send upstream to the
+subproject.
+
+
+OPTIONS FOR split
+-----------------
+--annotate=<annotation>::
+	This option is only valid for the split command.
++
+When generating synthetic history, add <annotation> as a prefix to each
+commit message.  Since we're creating new commits with the same commit
+message, but possibly different content, from the original commits, this
+can help to differentiate them and avoid confusion.
++
+Whenever you split, you need to use the same <annotation>, or else you
+don't have a guarantee that the new re-created history will be identical
+to the old one.  That will prevent merging from working correctly.  git
+subtree tries to make it work anyway, particularly if you use --rejoin,
+but it may not always be effective.
+
+-b <branch>::
+--branch=<branch>::
+	This option is only valid for the split command.
++
+After generating the synthetic history, create a new branch called
+<branch> that contains the new history.  This is suitable for immediate
+pushing upstream.  <branch> must not already exist.
+
+--ignore-joins::
+	This option is only valid for the split command.
++
+If you use '--rejoin', git subtree attempts to optimize its history
+reconstruction to generate only the new commits since the last
+'--rejoin'.  '--ignore-join' disables this behaviour, forcing it to
+regenerate the entire history.  In a large project, this can take a long
+time.
+
+--onto=<onto>::
+	This option is only valid for the split command.
++
+If your subtree was originally imported using something other than git
+subtree, its history may not match what git subtree is expecting.  In
+that case, you can specify the commit id <onto> that corresponds to the
+first revision of the subproject's history that was imported into your
+project, and git subtree will attempt to build its history from there.
++
+If you used 'git subtree add', you should never need this option.
+
+--rejoin::
+	This option is only valid for the split command.
++
+After splitting, merge the newly created synthetic history back into
+your main project.  That way, future splits can search only the part of
+history that has been added since the most recent --rejoin.
++
+If your split commits end up merged into the upstream subproject, and
+then you want to get the latest upstream version, this will allow git's
+merge algorithm to more intelligently avoid conflicts (since it knows
+these synthetic commits are already part of the upstream repository).
++
+Unfortunately, using this option results in 'git log' showing an extra
+copy of every new commit that was created (the original, and the
+synthetic one).
++
+If you do all your merges with '--squash', don't use '--rejoin' when you
+split, because you don't want the subproject's history to be part of
+your project anyway.
+
+
+EXAMPLE 1. Add command
+----------------------
+Let's assume that you have a local repository that you would like
+to add an external vendor library to. In this case we will add the
+git-subtree repository as a subdirectory of your already existing
+git-extensions repository in ~/git-extensions/:
+
+	$ git subtree add --prefix=git-subtree --squash \
+		git://github.com/apenwarr/git-subtree.git master
+
+'master' needs to be a valid remote ref and can be a different branch
+name
+
+You can omit the --squash flag, but doing so will increase the number
+of commits that are included in your local repository.
+
+We now have a ~/git-extensions/git-subtree directory containing code
+from the master branch of git://github.com/apenwarr/git-subtree.git
+in our git-extensions repository.
+
+EXAMPLE 2. Extract a subtree using commit, merge and pull
+---------------------------------------------------------
+Let's use the repository for the git source code as an example.
+First, get your own copy of the git.git repository:
+
+	$ git clone git://git.kernel.org/pub/scm/git/git.git test-git
+	$ cd test-git
+
+gitweb (commit 1130ef3) was merged into git as of commit
+0a8f4f0, after which it was no longer maintained separately. 
+But imagine it had been maintained separately, and we wanted to
+extract git's changes to gitweb since that time, to share with
+the upstream.  You could do this:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' \
+        	0a8f4f0^.. --onto=1130ef3 --rejoin \
+        	--branch gitweb-latest
+        $ gitk gitweb-latest
+        $ git push git@github.com:whatever/gitweb.git gitweb-latest:master
+        
+(We use '0a8f4f0^..' because that means "all the changes from
+0a8f4f0 to the current version, including 0a8f4f0 itself.")
+
+If gitweb had originally been merged using 'git subtree add' (or
+a previous split had already been done with --rejoin specified)
+then you can do all your splits without having to remember any
+weird commit ids:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' --rejoin \
+		--branch gitweb-latest2
+
+And you can merge changes back in from the upstream project just
+as easily:
+
+	$ git subtree pull --prefix=gitweb \
+		git@github.com:whatever/gitweb.git master
+
+Or, using '--squash', you can actually rewind to an earlier
+version of gitweb:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest~10
+
+Then make some changes:
+
+	$ date >gitweb/myfile
+	$ git add gitweb/myfile
+	$ git commit -m 'created myfile'
+
+And fast forward again:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest
+
+And notice that your change is still intact:
+	
+	$ ls -l gitweb/myfile
+
+And you can split it out and look at your changes versus
+the standard gitweb:
+
+	git log gitweb-latest..$(git subtree split --prefix=gitweb)
+
+EXAMPLE 3. Extract a subtree using branch
+-----------------------------------------
+Suppose you have a source directory with many files and
+subdirectories, and you want to extract the lib directory to its own
+git project. Here's a short way to do it:
+
+First, make the new repository wherever you want:
+
+	$ <go to the new location>
+	$ git init --bare
+
+Back in your original directory:
+
+	$ git subtree split --prefix=lib --annotate="(split)" -b split
+
+Then push the new branch onto the new empty repository:
+
+	$ git push <new-repo> split:master

+=========
+
+NAME
+----
+svn-fe - convert an SVN "dumpfile" to a fast-import stream
+
+SYNOPSIS
+--------
+[verse]
+mkfifo backchannel &&
+svnadmin dump --deltas REPO |
+	svn-fe [url] 3<backchannel |
+	git fast-import --cat-blob-fd=3 3>backchannel
+
+DESCRIPTION
+-----------
+
+Converts a Subversion dumpfile into input suitable for
+git-fast-import(1) and similar importers. REPO is a path to a
+Subversion repository mirrored on the local disk. Remote Subversion
+repositories can be mirrored on local disk using the `svnsync`
+command.
+
+Note: this tool is very young.  The details of its commandline
+interface may change in backward incompatible ways.
+
+INPUT FORMAT
+------------
+Subversion's repository dump format is documented in full in
+`notes/dump-load-format.txt` from the Subversion source tree.
+Files in this format can be generated using the 'svnadmin dump' or
+'svk admin dump' command.
+
+OUTPUT FORMAT
+-------------
+The fast-import format is documented by the git-fast-import(1)
+manual page.
+
+NOTES
+-----
+Subversion dumps do not record a separate author and committer for
+each revision, nor do they record a separate display name and email
+address for each author.  Like git-svn(1), 'svn-fe' will use the name
+
+---------
+user <user@UUID>
+---------
+
+as committer, where 'user' is the value of the `svn:author` property
+and 'UUID' the repository's identifier.
+
+To support incremental imports, 'svn-fe' puts a `git-svn-id` line at
+the end of each commit log message if passed a URL on the command
+line.  This line has the form `git-svn-id: URL@REVNO UUID`.
+
+The resulting repository will generally require further processing
+to put each project in its own repository and to separate the history
+of each branch.  The 'git filter-branch --subdirectory-filter' command
+may be useful for this purpose.
+
+BUGS
+----
+Empty directories and unknown properties are silently discarded.
+
+The exit status does not reflect whether an error was detected.

+appp.sh is a script that is supposed to be used together with ExternalEditor
+for Mozilla Thunderbird. It will let you include patches inline in e-mails
+in an easy way.
+
+Usage:
+- Generate the patch with git format-patch.
+- Start writing a new e-mail in Thunderbird.
+- Press the external editor button (or Ctrl-E) to run appp.sh
+- Select the previously generated patch file.
+- Finish editing the e-mail.
+
+Any text that is entered into the message editor before appp.sh is called
+will be moved to the section between the --- and the diffstat.
+
+All S-O-B:s and Cc:s in the patch will be added to the CC list.
+
+To set it up, just install External Editor and tell it to use appp.sh as the
+editor.
+
+Zenity is a required dependency.

-To syntax highlight git's commit messages, you need to:
-  1. Copy syntax/gitcommit.vim to vim's syntax directory:
-     $ mkdir -p $HOME/.vim/syntax
-     $ cp syntax/gitcommit.vim $HOME/.vim/syntax
-  2. Auto-detect the editing of git commit files:
-     $ cat >>$HOME/.vimrc <<'EOF'
-     autocmd BufNewFile,BufRead COMMIT_EDITMSG set filetype=gitcommit

+	   This trick arranges for messages to be emitted in the user's
+	   requested encoding, but avoids setting LC_CTYPE from the
+	   environment for the whole program.
+
+	   This primarily done to avoid a bug in vsnprintf in the GNU C
+	   Library [1]. which triggered a "your vsnprintf is broken" error
+	   on Git's own repository when inspecting v0.99.6~1 under a UTF-8
+	   locale.
+
+	   That commit contains a ISO-8859-1 encoded author name, which
+	   the locale aware vsnprintf(3) won't interpolate in the format
+	   argument, due to mismatch between the data encoding and the
+	   locale.
+
+	   Even if it wasn't for that bug we wouldn't want to use LC_CTYPE at
+	   this point, because it'd require auditing all the code that uses C
+	   functions whose semantics are modified by LC_CTYPE.
+
+	   But only setting LC_MESSAGES as we do creates a problem, since
+	   we declare the encoding of our PO files[2] the gettext
+	   implementation will try to recode it to the user's locale, but
+	   without LC_CTYPE it'll emit something like this on 'git init'
+	   under the Icelandic locale:
+
+	       Bj? til t?ma Git lind ? /hlagh/.git/
+
+	   Gettext knows about the encoding of our PO file, but we haven't
+	   told it about the user's encoding, so all the non-US-ASCII
+	   characters get encoded to question marks.
+
+	   But we're in luck! We can set LC_CTYPE from the environment
+	   only while we call nl_langinfo and
+	   bind_textdomain_codeset. That suffices to tell gettext what
+	   encoding it should emit in, so it'll now say:
+
+	       Bjó til tóma Git lind í /hlagh/.git/
+
+	   And the equivalent ISO-8859-1 string will be emitted under a
+	   ISO-8859-1 locale.
+
+	   With this change way we get the advantages of setting LC_CTYPE
+	   (talk to the user in his language/encoding), without the major
+	   drawbacks (changed semantics for C functions we rely on).
+
+	   However foreign functions using other message catalogs that
+	   aren't using our neat trick will still have a problem, e.g. if
+	   we have to call perror(3):
+
+	   #include <stdio.h>
+	   #include <locale.h>
+	   #include <errno.h>
+
+	   int main(void)
+	   {
+		   setlocale(LC_MESSAGES, "");
+		   setlocale(LC_CTYPE, "C");
+		   errno = ENODEV;
+		   perror("test");
+		   return 0;
+	   }
+
+	   Running that will give you a message with question marks:
+
+	   $ LANGUAGE= LANG=de_DE.utf8 ./test
+	   test: Kein passendes Ger?t gefunden
+
+	   The vsnprintf bug has been fixed since glibc 2.17.
+
+	   Then we could simply set LC_CTYPE from the environment, which would
+	   make things like the external perror(3) messages work.
+
+	   See t/t0203-gettext-setlocale-sanity.sh's "gettext.c" tests for
+	   regression tests.
+
+	   1. http://sourceware.org/bugzilla/show_bug.cgi?id=6530

-##
-## The patch application may fail in the middle.  In which case:

-## (2) re-run applymbox with -c .dotest/msg-number for the current one.
-## Pay a special attention to the commit log message if you do this and

-## message to msg-clean every time it is run.

+    #
+    # General CVS numbering scheme:
+    #   - Basic mainline branch numbers: "1.1", "1.2", "1.3", etc.
+    #   - Result of "cvs checkin -r" (possible, but not really
+    #     recommended): "2.1", "2.2", etc
+    #   - Branch tag: "1.2.0.n", where "1.2" is revision it was branched
+    #     from, "0" is a magic placeholder that identifies it as a
+    #     branch tag instead of a version tag, and n is 2 times the
+    #     branch number off of "1.2", starting with "2".
+    #   - Version on a branch: "1.2.n.x", where "1.2" is branch-from, "n"
+    #     is branch number off of "1.2" (like n above), and "x" is
+    #     the version number on the branch.
+    #   - Branches can branch off of branches: "1.3.2.7.4.1" (even number
+    #     of components).
+    #   - Odd "n"s are used by "vendor branches" that result
+    #     from "cvs import".  Vendor branches have additional
+    #     strangeness in the sense that the main rcs "head" of the main
+    #     branch will (temporarily until first normal commit) point
+    #     to the version on the vendor branch, rather than the actual
+    #     main branch.  (FUTURE: This may provide an opportunity
+    #     to use "strange" revision numbers for fast-forward-merged
+    #     branch tip when CVS client is asking for the main branch.)
+    #
+    # git-cvsserver CVS-compatible special numbering schemes:
+    #   - Currently git-cvsserver only tries to be identical to CVS for
+    #     simple "1.x" numbers on the "main" branch (as identified
+    #     by the module name that was originally cvs checkout'ed).
+    #   - The database only stores the "x" part, for historical reasons.
+    #     But most of the rest of the cvsserver preserves
+    #     and thinks using the full revision number.
+    #   - To handle non-linear history, it uses a version of the form
+    #     "2.1.1.2000.b.b.b."..., where the 2.1.1.2000 is to help uniquely
+    #     identify this as a special revision number, and there are
+    #     20 b's that together encode the sha1 git commit from which
+    #     this version of this file originated.  Each b is
+    #     the numerical value of the corresponding byte plus
+    #     100.
+    #      - "plus 100" avoids "0"s, and also reduces the
+    #        likelihood of a collision in the case that someone someday
+    #        writes an import tool that tries to preserve original
+    #        CVS revision numbers, and the original CVS data had done
+    #        lots of branches off of branches and other strangeness to
+    #        end up with a real version number that just happens to look
+    #        like this special revision number form.  Also, if needed
+    #        there are several ways to extend/identify alternative encodings
+    #        within the "2.1.1.2000" part if necessary.
+    #      - Unlike real CVS revisions, you can't really reconstruct what
+    #        relation a revision of this form has to other revisions.

+You would first need to have a working "git".  Your distribution may
+have it as "git-core" package (do not get "GNU Interactive Tools" --
+that is a different "git").  You would also need GNU gettext toolchain
+to test the resulting translation out.  Although you can work on message
+translation files with a regular text editor, it is a good idea to have
+specialized so-called "po file editors" (e.g. emacs po-mode, KBabel,
+poedit, GTranslator --- any of them would work well).  Please install
+them.
+
+You would then need to clone the git-gui project repository and create
+a feature branch to begin working:
+
+	$ git clone git://repo.or.cz/git-gui.git
+	$ cd git-gui.git
+	$ git checkout -b my-translation
+
+The "git checkout" command creates a new branch to keep your work
+isolated and to make it simple to post your patch series when
+completed.  You will be working on this branch.
+
+
+2. Starting a new language.
+
+In the git-gui directory is a po/ subdirectory.  It has a handful of
+files whose names end with ".po".  Is there a file that has messages
+in your language?
+
+If you do not know what your language should be named, you need to find
+it.  This currently follows ISO 639-1 two letter codes:
+
+	http://www.loc.gov/standards/iso639-2/php/code_list.php
+
+For example, if you are preparing a translation for Afrikaans, the
+language code is "af".  If there already is a translation for your
+language, you do not have to perform any step in this section, but keep
+reading, because we are covering the basics.
+
+If you did not find your language, you would need to start one yourself.
+Copy po/git-gui.pot file to po/af.po (replace "af" with the code for
+your language).  Edit the first several lines to match existing *.po
+files to make it clear this is a translation table for git-gui project,
+and you are the primary translator.  The result of your editing would
+look something like this:
+
+    # Translation of git-gui to Afrikaans
+    # Copyright (C) 2007 Shawn Pearce
+    # This file is distributed under the same license as the git-gui package.
+    # YOUR NAME <YOUR@E-MAIL.ADDRESS>, 2007.
+    #
+    #, fuzzy
+    msgid ""
+    msgstr ""
+    "Project-Id-Version: git-gui\n"
+    "Report-Msgid-Bugs-To: \n"
+    "POT-Creation-Date: 2007-07-24 22:19+0300\n"
+    "PO-Revision-Date: 2007-07-25 18:00+0900\n"
+    "Last-Translator: YOUR NAME <YOUR@E-MAIL.ADDRESS>\n"
+    "Language-Team: Afrikaans\n"
+    "MIME-Version: 1.0\n"
+    "Content-Type: text/plain; charset=UTF-8\n"
+    "Content-Transfer-Encoding: 8bit\n"
+
+You will find many pairs of a "msgid" line followed by a "msgstr" line.
+These pairs define how messages in git-gui application are translated to
+your language.  Your primarily job is to fill in the empty double quote
+pairs on msgstr lines with the translation of the strings on their
+matching msgid lines.  A few tips:
+
+ - Control characters, such as newlines, are written in backslash
+   sequence similar to string literals in the C programming language.
+   When the string given on a msgid line has such a backslash sequence,
+   you would typically want to have corresponding ones in the string on
+   your msgstr line.
+
+ - Some messages contain an optional context indicator at the end,
+   for example "@@noun" or "@@verb".  This indicator allows the
+   software to select the correct translation depending upon the use.
+   The indicator is not actually part of the message and will not
+   be shown to the end-user.
+
+   If your language does not require a different translation you
+   will still need to translate both messages.
+
+ - Often the messages being translated are format strings given to
+   "printf()"-like functions.  Make sure "%s", "%d", and "%%" in your
+   translated messages match the original.
+
+   When you have to change the order of words, you can add "<number>$"
+   between '%' and the conversion ('s', 'd', etc.) to say "<number>-th
+   parameter to the format string is used at this point".  For example,
+   if the original message is like this:
+
+	"Length is %d, Weight is %d"
+
+   and if for whatever reason your translation needs to say weight first
+   and then length, you can say something like:
+
+	"WEIGHT IS %2$d, LENGTH IS %1$d"
+
+   A format specification with a '*' (asterisk) refers to *two* arguments
+   instead of one, hence the succeeding argument number is two higher
+   instead of one. So, a message like this
+
+	"%s ... %*i of %*i %s (%3i%%)"
+
+   is equivalent to
+
+	"%1$s ... %2$*i of %4$*i %6$s (%7$3i%%)"
+
+ - A long message can be split across multiple lines by ending the
+   string with a double quote, and starting another string on the next
+   line with another double quote.  They will be concatenated in the
+   result.  For example:
+
+   #: lib/remote_branch_delete.tcl:189
+   #, tcl-format
+   msgid ""
+   "One or more of the merge tests failed because you have not fetched the "
+   "necessary commits.  Try fetching from %s first."
+   msgstr ""
+   "HERE YOU WILL WRITE YOUR TRANSLATION OF THE ABOVE LONG "
+   "MESSAGE IN YOUR LANGUAGE."
+
+You can test your translation by running "make install", which would
+create po/af.msg file and installs the result, and then running the
+resulting git-gui under your locale:
+
+	$ make install
+	$ LANG=af git-gui
+
+There is a trick to test your translation without first installing:
+
+	$ make
+	$ LANG=af ./git-gui.sh
+
+When you are satisfied with your translation, commit your changes then submit
+your patch series to the maintainer and the Git mailing list:
+
+	$ edit po/af.po
+	... be sure to update Last-Translator: and
+	... PO-Revision-Date: lines.
+	$ git add po/af.po
+	$ git commit -s -m 'git-gui: added Afrikaans translation.'
+	$ git send-email --to 'git@vger.kernel.org' \
+	   --cc 'Pat Thoyts <patthoyts@users.sourceforge.net>' \
+	   --subject 'git-gui: Afrikaans translation' \
+	   master..
+
+
+3. Updating your translation.
+
+There may already be a translation for your language, and you may want
+to contribute an update.  This may be because you would want to improve
+the translation of existing messages, or because the git-gui software
+itself was updated and there are new messages that need translation.
+
+In any case, make sure you are up-to-date before starting your work:
+
+	$ git checkout master
+	$ git pull
+
+In the former case, you will edit po/af.po (again, replace "af" with
+your language code), and after testing and updating the Last-Translator:
+and PO-Revision-Date: lines, "add/commit/push" as in the previous
+section.
+
+By comparing "POT-Creation-Date:" line in po/git-gui.pot file and
+po/af.po file, you can tell if there are new messages that need to be
+translated.  You would need the GNU gettext package to perform this
+step.
+
+	$ msgmerge -U po/af.po po/git-gui.pot
+
+This updates po/af.po (again, replace "af" with your language
+code) so that it contains msgid lines (i.e. the original) that
+your translation did not have before.  There are a few things to
+watch out for:
+
+ - The original text in English of an older message you already
+   translated might have been changed.  You will notice a comment line
+   that begins with "#, fuzzy" in front of such a message.  msgmerge
+   tool made its best effort to match your old translation with the
+   message from the updated software, but you may find cases that it
+   matched your old translated message to a new msgid and the pairing
+   does not make any sense -- you would need to fix them, and then
+   remove the "#, fuzzy" line from the message (your fixed translation
+   of the message will not be used before you remove the marker).
+
+ - New messages added to the software will have msgstr lines with empty
+   strings.  You would need to translate them.
+
+The po/git-gui.pot file is updated by the internationalization
+coordinator from time to time.  You _could_ update it yourself, but
+translators are discouraged from doing so because we would want all
+language teams to be working off of the same version of git-gui.pot.
+
+****************************************************************
+
+This section is a note to the internationalization coordinator, and
+translators do not have to worry about it too much.
+
+The message template file po/git-gui.pot needs to be kept up to date
+relative to the software the translations apply to, and it is the
+responsibility of the internationalization coordinator.
+
+When updating po/git-gui.pot file, however, _never_ run "msgmerge -U
+po/xx.po" for individual language translations, unless you are absolutely
+sure that there is no outstanding work on translation for language xx.
+Doing so will create unnecessary merge conflicts and force needless
+re-translation on translators.  The translator however may not have access
+to the msgmerge tool, in which case the coordinator may run it for the
+translator as a service.
+
+But mistakes do happen.  Suppose a translation was based on an older
+version X, the POT file was updated at version Y and then msgmerge was run
+at version Z for the language, and the translator sent in a patch based on
+version X:
+
+         ? translated
+        /
+    ---X---Y---Z (master)
+
+The coordinator could recover from such a mistake by first applying the
+patch to X, replace the translated file in Z, and then running msgmerge
+again based on the updated POT file and commit the result.  The sequence
+would look like this:
+
+    $ git checkout X
+    $ git am -s xx.patch
+    $ git checkout master
+    $ git checkout HEAD@{1} po/xx.po
+    $ msgmerge -U po/xx.po po/git-gui.pot
+    $ git commit -c HEAD@{1} po/xx.po
+
+State in the message that the translated messages are based on a slightly
+older version, and msgmerge was run to incorporate changes to message
+templates from the updated POT file.  The result needs to be further
+translated, but at least the messages that were updated by the patch that
+were not changed by the POT update will survive the process and do not
+need to be re-translated.

-original <branch> and remove the .dotest working files, use the command
-git rebase --abort instead.
-
-Note that if <branch> is not specified on the command line, the
-currently checked out branch is used.  You must be in the top
-directory of your project to start (or continue) a rebase.
-
-Example:       git-rebase master~1 topic
-
-        A---B---C topic                   A'\''--B'\''--C'\'' topic
-       /                   -->           /

+GIT web Interface (gitweb) Installation
+=======================================
+
+First you have to generate gitweb.cgi from gitweb.perl using
+"make gitweb", then "make install-gitweb" appropriate files
+(gitweb.cgi, gitweb.js, gitweb.css, git-logo.png and git-favicon.png)
+to their destination. For example if git was (or is) installed with
+/usr prefix and gitwebdir is /var/www/cgi-bin, you can do
+
+	$ make prefix=/usr gitweb                            ;# as yourself
+	# make gitwebdir=/var/www/cgi-bin install-gitweb     ;# as root
+
+Alternatively you can use autoconf generated ./configure script to
+set up path to git binaries (via config.mak.autogen), so you can write
+instead
+
+	$ make configure                     ;# as yourself
+	$ ./configure --prefix=/usr          ;# as yourself
+	$ make gitweb                        ;# as yourself
+	# make gitwebdir=/var/www/cgi-bin \
+	       install-gitweb                ;# as root
+
+The above example assumes that your web server is configured to run
+[executable] files in /var/www/cgi-bin/ as server scripts (as CGI
+scripts).
+
+
+Requirements
+------------
+
+ - Core git tools
+ - Perl
+ - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename.
+ - web server
+
+The following optional Perl modules are required for extra features
+ - Digest::MD5 - for gravatar support
+ - CGI::Fast and FCGI - for running gitweb as FastCGI script
+ - HTML::TagCloud - for fancy tag cloud in project list view
+ - HTTP::Date or Time::ParseDate - to support If-Modified-Since for feeds
+
+
+Build time configuration
+------------------------
+
+See also "How to configure gitweb for your local system" section below.
+
+- There are many configuration variables which affect building of
+  gitweb.cgi; see "default configuration for gitweb" section in main
+  (top dir) Makefile, and instructions for building gitweb target.
+
+  One of the most important is where to find the git wrapper binary. Gitweb
+  tries to find the git wrapper at $(bindir)/git, so you have to set $bindir
+  when building gitweb.cgi, or $prefix from which $bindir is derived. If
+  you build and install gitweb together with the rest of the git suite,
+  there should be no problems. Otherwise, if git was for example
+  installed from a binary package, you have to set $prefix (or $bindir)
+  accordingly.
+
+- Another important issue is where are git repositories you want to make
+  available to gitweb. By default gitweb searches for repositories under
+  /pub/git; if you want to have projects somewhere else, like /home/git,
+  use GITWEB_PROJECTROOT build configuration variable.
+
+  By default all git repositories under projectroot are visible and
+  available to gitweb. The list of projects is generated by default by
+  scanning the projectroot directory for git repositories. This can be
+  changed (configured) as described in "Gitweb repositories" section
+  below.
+
+  Note that gitweb deals directly with the object database, and does not
+  need a working directory; the name of the project is the name of its
+  repository object database, usually projectname.git for bare
+  repositories. If you want to provide gitweb access to non-bare (live)
+  repositories, you can make projectname.git a symbolic link under
+  projectroot linking to projectname/.git (but it is just
+  a suggestion).
+
+- You can control where gitweb tries to find its main CSS style file,
+  its JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS
+  GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default
+  gitweb tries to find them in the same directory as gitweb.cgi script.
+
+- You can optionally generate minified versions of gitweb.js and gitweb.css
+  by defining the JSMIN and CSSMIN build configuration variables. By default
+  the non-minified versions will be used. NOTE: if you enable this option,
+  substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and
+  gitweb.css in the help files.
+
+
+How to configure gitweb for your local system
+---------------------------------------------
+
+You can specify the following configuration variables when building GIT:
+
+ * GIT_BINDIR
+   Points where to find the git executable.  You should set it up to
+   the place where the git binary was installed (usually /usr/bin) if you
+   don't install git from sources together with gitweb.  [Default: $(bindir)]
+ * GITWEB_SITENAME
+   Shown in the title of all generated pages, defaults to the server name
+   (SERVER_NAME CGI environment variable) if not set. [No default]
+ * GITWEB_PROJECTROOT
+   The root directory for all projects shown by gitweb. Must be set
+   correctly for gitweb to find repositories to display.  See also
+   "Gitweb repositories" in the INSTALL file for gitweb.  [Default: /pub/git]
+ * GITWEB_PROJECT_MAXDEPTH
+   The filesystem traversing limit for getting the project list; the number
+   is taken as depth relative to the projectroot.  It is used when
+   GITWEB_LIST is a directory (or is not set; then project root is used).
+   This is meant to speed up project listing on large work trees by limiting
+   search depth.  [Default: 2007]
+ * GITWEB_LIST
+   Points to a directory to scan for projects (defaults to project root
+   if not set / if empty) or to a file with explicit listing of projects
+   (together with projects' ownership). See "Generating projects list
+   using gitweb" in INSTALL file for gitweb to find out how to generate
+   such file from scan of a directory. [No default, which means use root
+   directory for projects]
+ * GITWEB_EXPORT_OK
+   Show repository only if this file exists (in repository).  Only
+   effective if this variable evaluates to true.  [No default / Not set]
+ * GITWEB_STRICT_EXPORT
+   Only allow viewing of repositories also shown on the overview page.
+   This for example makes GITWEB_EXPORT_OK to decide if repository is
+   available and not only if it is shown.  If GITWEB_LIST points to
+   file with list of project, only those repositories listed would be
+   available for gitweb.  [No default]
+ * GITWEB_HOMETEXT
+   Points to an .html file which is included on the gitweb project
+   overview page ('projects_list' view), if it exists.  Relative to
+   gitweb.cgi script.  [Default: indextext.html]
+ * GITWEB_SITE_HTML_HEAD_STRING
+   html snippet to include in the <head> section of each page. [No default]
+ * GITWEB_SITE_HEADER
+   Filename of html text to include at top of each page.  Relative to
+   gitweb.cgi script.  [No default]
+ * GITWEB_SITE_FOOTER
+   Filename of html text to include at bottom of each page.  Relative to
+   gitweb.cgi script.  [No default]
+ * GITWEB_HOME_LINK_STR
+   String of the home link on top of all pages, leading to $home_link
+   (usually main gitweb page, which means projects list).  Used as first
+   part of gitweb view "breadcrumb trail": <home> / <project> / <view>.
+   [Default: projects]
+ * GITWEB_SITENAME
+   Name of your site or organization to appear in page titles.  Set it
+   to something descriptive for clearer bookmarks etc.  If not set
+   (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if
+   SERVER_NAME CGI environment variable is not set (e.g. if running
+   gitweb as standalone script).  [No default]
+ * GITWEB_BASE_URL
+   Git base URLs used for URL to where fetch project from, i.e. full
+   URL is "$git_base_url/$project".  Shown on projects summary page.
+   Repository URL for project can be also configured per repository; this
+   takes precedence over URLs composed from base URL and a project name.
+   Note that you can setup multiple base URLs (for example one for
+   git:// protocol access, another for http:// access) from the gitweb
+   config file.  [No default]
+ * GITWEB_CSS
+   Points to the location where you put gitweb.css on your web server
+   (or to be more generic, the URI of gitweb stylesheet).  Relative to the
+   base URI of gitweb.  Note that you can setup multiple stylesheets from
+   the gitweb config file.  [Default: static/gitweb.css (or
+   static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier
+   is used)]
+ * GITWEB_JS
+   Points to the location where you put gitweb.js on your web server
+   (or to be more generic URI of JavaScript code used by gitweb).
+   Relative to base URI of gitweb.  [Default: static/gitweb.js (or
+   static/gitweb.min.js if JSMIN build variable is defined / JavaScript
+   minifier is used)]
+ * CSSMIN, JSMIN
+   Invocation of a CSS minifier or a JavaScript minifier, respectively,
+   working as a filter (source on standard input, minified result on
+   standard output).  If set, it is used to generate a minified version of
+   'static/gitweb.css' or 'static/gitweb.js', respectively.  *Note* that
+   minified files would have *.min.css and *.min.js extension, which is
+   important if you also set GITWEB_CSS and/or GITWEB_JS.  [No default]
+ * GITWEB_LOGO
+   Points to the location where you put git-logo.png on your web server
+   (or to be more generic URI of logo, 72x27 size, displayed in top right
+   corner of each gitweb page, and used as logo for Atom feed).  Relative
+   to base URI of gitweb.  [Default: static/git-logo.png]
+ * GITWEB_FAVICON
+   Points to the location where you put git-favicon.png on your web server
+   (or to be more generic URI of favicon, assumed to be image/png type;
+   web browsers that support favicons (website icons) may display them
+   in the browser's URL bar and next to site name in bookmarks).  Relative
+   to base URI of gitweb.  [Default: static/git-favicon.png]
+ * GITWEB_CONFIG
+   This Perl file will be loaded using 'do' and can be used to override any
+   of the options above as well as some other options -- see the "Runtime
+   gitweb configuration" section below, and top of 'gitweb.cgi' for their
+   full list and description.  If the environment variable GITWEB_CONFIG
+   is set when gitweb.cgi is executed, then the file specified in the
+   environment variable will be loaded instead of the file specified
+   when gitweb.cgi was created.  [Default: gitweb_config.perl]
+ * GITWEB_CONFIG_SYSTEM
+   This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG
+   does not exist.  If the environment variable GITWEB_CONFIG_SYSTEM is set
+   when gitweb.cgi is executed, then the file specified in the environment
+   variable will be loaded instead of the file specified when gitweb.cgi was
+   created.  [Default: /etc/gitweb.conf]
+ * HIGHLIGHT_BIN
+   Path to the highlight executable to use (must be the one from
+   http://www.andre-simon.de due to assumptions about parameters and output).
+   Useful if highlight is not installed on your webserver's PATH.
+   [Default: highlight]
+
+Build example
+~~~~~~~~~~~~~
+
+- To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper
+  is installed at /usr/local/bin/git, the repositories (projects)
+  we want to display are under /home/local/scm, and you do not use
+  minifiers, you can do
+
+	make GITWEB_PROJECTROOT="/home/local/scm" \
+	     GITWEB_JS="gitweb/static/gitweb.js" \
+	     GITWEB_CSS="gitweb/static/gitweb.css" \
+	     GITWEB_LOGO="gitweb/static/git-logo.png" \
+	     GITWEB_FAVICON="gitweb/static/git-favicon.png" \
+	     bindir=/usr/local/bin \
+	     gitweb
+
+	make gitwebdir=/var/www/cgi-bin/gitweb install-gitweb
+
+
+Gitweb config file
+------------------
+
+See also "Runtime gitweb configuration" section in README file
+for gitweb (in gitweb/README), and gitweb.conf(5) manpage.
+
+- You can configure gitweb further using the per-instance gitweb configuration file;
+  by default this is a file named gitweb_config.perl in the same place as
+  gitweb.cgi script. You can control the default place for the config file
+  using the GITWEB_CONFIG build configuration variable, and you can set it
+  using the GITWEB_CONFIG environment variable. If this file does not
+  exist, gitweb looks for a system-wide configuration file, normally
+  /etc/gitweb.conf. You can change the default using the
+  GITWEB_CONFIG_SYSTEM build configuration variable, and override it
+  through the GITWEB_CONFIG_SYSTEM environment variable.
+
+  Note that the GITWEB_CONFIG_SYSTEM system-wide configuration file is
+  only used for instances that lack per-instance configuration file.
+  You can use GITWEB_CONFIG_COMMON common system-wide configuration
+  file (normally /etc/gitweb-common.conf) to keep common default
+  settings that apply to all instances.  Settings from per-instance or
+  system-wide configuration file override those from common system-wide
+  configuration file.
+
+- The gitweb config file is a fragment of perl code. You can set variables
+  using "our $variable = value"; text from "#" character until the end
+  of a line is ignored. See perlsyn(1) for details.
+
+  See the top of gitweb.perl file for examples of customizable options.
+
+Config file example
+~~~~~~~~~~~~~~~~~~~
+
+To enable blame, pickaxe search, and snapshot support, while allowing
+individual projects to turn them off, put the following in your
+GITWEB_CONFIG file:
+
+	$feature{'blame'}{'default'} = [1];
+	$feature{'blame'}{'override'} = 1;
+
+	$feature{'pickaxe'}{'default'} = [1];
+	$feature{'pickaxe'}{'override'} = 1;
+
+	$feature{'snapshot'}{'default'} = ['zip', 'tgz'];
+	$feature{'snapshot'}{'override'} = 1;
+
+If you allow overriding for the snapshot feature, you can specify which
+snapshot formats are globally disabled. You can also add any command line
+options you want (such as setting the compression level). For instance,
+you can disable Zip compressed snapshots and set GZip to run at level 6 by
+adding the following lines to your $GITWEB_CONFIG:
+
+	$known_snapshot_formats{'zip'}{'disabled'} = 1;
+	$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
+
+
+Gitweb repositories
+-------------------
+
+By default gitweb shows all git repositories under single common repository
+root on a local filesystem; see description of GITWEB_PROJECTROOT build-time
+configuration variable above (and also of GITWEB_LIST).
+
+More advanced usage, like limiting access or visibility of repositories and
+managing multiple roots are described on gitweb manpage.

 GIT web Interface
 =================
 
-The one working on:
-  http://www.kernel.org/git/
-
 From the git version 1.4.0 gitweb is bundled with git.
 
 
-How to configure gitweb for your local system
----------------------------------------------
-
-You can specify the following configuration variables when building GIT:
- * GITWEB_SITENAME
-   Shown in the title of all generated pages, defaults to the servers name.
- * GITWEB_PROJECTROOT
-   The root directory for all projects shown by gitweb.
- * GITWEB_LIST
-   points to a directory to scan for projects (defaults to project root)
-   or to a file for explicit listing of projects.
- * GITWEB_HOMETEXT
-   points to an .html file which is included on the gitweb project
-   overview page.
- * GITWEB_CSS
-   Points to the location where you put gitweb.css on your web server.
- * GITWEB_LOGO
-   Points to the location where you put git-logo.png on your web server.
- * GITWEB_CONFIG
-   This file will be loaded using 'require' and can be used to override any
-   of the options above as well as some other options - see the top of
-   'gitweb.cgi' for their full list and description.  If the environment
-   $GITWEB_CONFIG is set when gitweb.cgi is executed the file in the
-   environment variable will be loaded instead of the file
-   specified when gitweb.cgi was created.
+Build time gitweb configuration
+-------------------------------
+There are many configuration variables which affect building gitweb (among
+others creating gitweb.cgi out of gitweb.perl by replacing placeholders such
+as `++GIT_BINDIR++` by their build-time values).
+
+Building and installing gitweb is described in gitweb's INSTALL file
+(in 'gitweb/INSTALL').
 
 
 Runtime gitweb configuration
 ----------------------------
+Gitweb obtains configuration data from the following sources in the
+following order:
 
-You can adjust gitweb behaviour using the file specified in `GITWEB_CONFIG`
-(defaults to 'gitweb_config.perl' in the same directory as the CGI).
-See the top of 'gitweb.cgi' for the list of variables and some description.
-The most notable thing that is not configurable at compile time are the
-optional features, stored in the '%features' variable. You can find further
-description on how to reconfigure the default features setting in your
-`GITWEB_CONFIG` or per-project in `project.git/config` inside 'gitweb.cgi'.
+1. built-in values (some set during build stage),
+2. common system-wide configuration file (`GITWEB_CONFIG_COMMON`,
+   defaults to '/etc/gitweb-common.conf'),
+3. either per-instance configuration file (`GITWEB_CONFIG`, defaults to
+   'gitweb_config.perl' in the same directory as the installed gitweb),
+   or if it does not exists then system-wide configuration file
+   (`GITWEB_CONFIG_SYSTEM`, defaults to '/etc/gitweb.conf').
 
+Values obtained in later configuration files override values obtained earlier
+in above sequence.
 
-Webserver configuration
------------------------
+You can read defaults in system-wide GITWEB_CONFIG_SYSTEM from GITWEB_CONFIG
+by adding
 
-If you want to have one URL for both gitweb and your http://
-repositories, you can configure apache like this:
+  read_config_file($GITWEB_CONFIG_SYSTEM);
 
-<VirtualHost www:80>
-    ServerName git.domain.org
-    DocumentRoot /pub/git
-    RewriteEngine on
-    RewriteRule ^/(.*\.git/(?!/?(info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
-    SetEnv	GITWEB_CONFIG	/etc/gitweb.conf
-</VirtualHost>
+at very beginning of per-instance GITWEB_CONFIG file.  In this case
+settings in said per-instance file will override settings from
+system-wide configuration file.  Note that read_config_file checks
+itself that the $GITWEB_CONFIG_SYSTEM file exists.
+
+The most notable thing that is not configurable at compile time are the
+optional features, stored in the '%features' variable.
 
-The above configuration expects your public repositories to live under
-/pub/git and will serve them as http://git.domain.org/dir-under-pub-git,
-both as cloneable GIT URL and as browseable gitweb interface.
-If you then start your git-daemon with --base-path=/pub/git --export-all
-then you can even use the git:// URL with exactly the same path.
+Ultimate description on how to reconfigure the default features setting
+in your `GITWEB_CONFIG` or per-project in `project.git/config` can be found
+as comments inside 'gitweb.cgi'.
 
-Setting the environment variable GITWEB_CONFIG will tell gitweb to use
-the named file (i.e. in this example /etc/gitweb.conf) as a
-configuration for gitweb.  Perl variables defined in here will
-override the defaults given at the head of the gitweb.perl (or
-gitweb.cgi).  Look at the comments in that file for information on
-which variables and what they mean.
+See also gitweb.conf(5) manpage.
 
 
+Web server configuration
+------------------------
+Gitweb can be run as CGI script, as legacy mod_perl application (using
+ModPerl::Registry), and as FastCGI script.  You can find some simple examples
+in "Example web server configuration" section in INSTALL file for gitweb (in
+gitweb/INSTALL).
+
+See "Webserver configuration" and "Advanced web server setup" sections in
+gitweb(1) manpage.

+GIT web interface (gitweb) - JavaScript
+=======================================
+
+This directory holds JavaScript code used by gitweb (GIT web interface).
+Scripts from there would be concatenated together in the order specified
+by gitweb/Makefile into gitweb/static/gitweb.js, during building of
+gitweb/gitweb.cgi (during gitweb building).  The resulting file (or its
+minification) would then be installed / deployed together with gitweb.
+
+Scripts in 'lib/' subdirectory compose generic JavaScript library,
+providing features required by gitweb but in no way limited to gitweb
+only.  In the future those scripts could be replaced by some JavaScript
+library / framework, like e.g. jQuery, YUI, Prototype, MooTools, Dojo,
+ExtJS, Script.aculo.us or SproutCore.
+
+All scripts that manipulate gitweb output should be put outside 'lib/',
+directly in this directory ('gitweb/static/js/').  Those scripts would
+have to be rewritten if gitweb moves to using some JavaScript library.
+
+See also comments in gitweb/Makefile.

+ * This function implements the Damerau-Levenshtein algorithm to
+ * calculate a distance between strings.
+ *
+ * Basically, it says how many letters need to be swapped, substituted,
+ * deleted from, or added to string1, at least, to get string2.
+ *
+ * The idea is to build a distance matrix for the substrings of both
+ * strings.  To avoid a large space complexity, only the last three rows
+ * are kept in memory (if swaps had the same or higher cost as one deletion
+ * plus one insertion, only two rows would be needed).
+ *
+ * At any stage, "i + 1" denotes the length of the current substring of
+ * string1 that the distance is calculated for.
+ *
+ * row2 holds the current row, row1 the previous row (i.e. for the substring
+ * of string1 of length "i"), and row0 the row before that.
+ *
+ * In other words, at the start of the big loop, row2[j + 1] contains the
+ * Damerau-Levenshtein distance between the substring of string1 of length
+ * "i" and the substring of string2 of length "j + 1".
+ *
+ * All the big loop does is determine the partial minimum-cost paths.
+ *
+ * It does so by calculating the costs of the path ending in characters
+ * i (in string1) and j (in string2), respectively, given that the last
+ * operation is a substitution, a swap, a deletion, or an insertion.
+ *
+ * This implementation allows the costs to be weighted:
+ *
+ * - w (as in "sWap")
+ * - s (as in "Substitution")
+ * - a (for insertion, AKA "Add")
+ * - d (as in "Deletion")
+ *
+ * Note that this algorithm calculates a distance _iff_ d == a.

+
+/*
+ * File write-locks as used by Git.
+ *
+ * The lockfile API serves two purposes:
+ *
+ * * Mutual exclusion and atomic file updates. When we want to change
+ *   a file, we create a lockfile `<filename>.lock`, write the new
+ *   file contents into it, and then rename the lockfile to its final
+ *   destination `<filename>`. We create the `<filename>.lock` file
+ *   with `O_CREAT|O_EXCL` so that we can notice and fail if somebody
+ *   else has already locked the file, then atomically rename the
+ *   lockfile to its final destination to commit the changes and
+ *   unlock the file.
+ *
+ * * Automatic cruft removal. If the program exits after we lock a
+ *   file but before the changes have been committed, we want to make
+ *   sure that we remove the lockfile. This is done by remembering the
+ *   lockfiles we have created in a linked list and setting up an
+ *   `atexit(3)` handler and a signal handler that clean up the
+ *   lockfiles. This mechanism ensures that outstanding lockfiles are
+ *   cleaned up if the program exits (including when `die()` is
+ *   called) or if the program is terminated by a signal.
+ *
+ * Please note that lockfiles only block other writers. Readers do not
+ * block, but they are guaranteed to see either the old contents of
+ * the file or the new contents of the file (assuming that the
+ * filesystem implements `rename(2)` atomically).
+ *
+ * Most of the heavy lifting is done by the tempfile module (see
+ * "tempfile.h").
+ *
+ * Calling sequence
+ * ----------------
+ *
+ * The caller:
+ *
+ * * Allocates a `struct lock_file` either as a static variable or on
+ *   the heap, initialized to zeros. Once you use the structure to
+ *   call the `hold_lock_file_for_*()` family of functions, it belongs
+ *   to the lockfile subsystem and its storage must remain valid
+ *   throughout the life of the program (i.e. you cannot use an
+ *   on-stack variable to hold this structure).
+ *
+ * * Attempts to create a lockfile by calling `hold_lock_file_for_update()`.
+ *
+ * * Writes new content for the destination file by either:
+ *
+ *   * writing to the file descriptor returned by the
+ *     `hold_lock_file_for_*()` functions (also available via
+ *     `lock->fd`).
+ *
+ *   * calling `fdopen_lock_file()` to get a `FILE` pointer for the
+ *     open file and writing to the file using stdio.
+ *
+ * When finished writing, the caller can:
+ *
+ * * Close the file descriptor and rename the lockfile to its final
+ *   destination by calling `commit_lock_file()` or
+ *   `commit_lock_file_to()`.
+ *
+ * * Close the file descriptor and remove the lockfile by calling
+ *   `rollback_lock_file()`.
+ *
+ * * Close the file descriptor without removing or renaming the
+ *   lockfile by calling `close_lock_file()`, and later call
+ *   `commit_lock_file()`, `commit_lock_file_to()`,
+ *   `rollback_lock_file()`, or `reopen_lock_file()`.
+ *
+ * Even after the lockfile is committed or rolled back, the
+ * `lock_file` object must not be freed or altered by the caller.
+ * However, it may be reused; just pass it to another call of
+ * `hold_lock_file_for_update()`.
+ *
+ * If the program exits before `commit_lock_file()`,
+ * `commit_lock_file_to()`, or `rollback_lock_file()` is called, the
+ * tempfile module will close and remove the lockfile, thereby rolling
+ * back any uncommitted changes.
+ *
+ * If you need to close the file descriptor you obtained from a
+ * `hold_lock_file_for_*()` function yourself, do so by calling
+ * `close_lock_file()`. See "tempfile.h" for more information.
+ *
+ *
+ * Under the covers, a lockfile is just a tempfile with a few helper
+ * functions. In particular, the state diagram and the cleanup
+ * machinery are all implemented in the tempfile module.
+ *
+ *
+ * Error handling
+ * --------------
+ *
+ * The `hold_lock_file_for_*()` functions return a file descriptor on
+ * success or -1 on failure (unless `LOCK_DIE_ON_ERROR` is used; see
+ * "flags" below). On errors, `errno` describes the reason for
+ * failure. Errors can be reported by passing `errno` to
+ * `unable_to_lock_message()` or `unable_to_lock_die()`.
+ *
+ * Similarly, `commit_lock_file`, `commit_lock_file_to`, and
+ * `close_lock_file` return 0 on success. On failure they set `errno`
+ * appropriately, do their best to roll back the lockfile, and return
+ * -1.

- * files (see "base_name_compare"), so you'll never see file/directory
- * conflicts, because they won't ever compare the same.
- *
- * IOW, if a directory changes to a filename, it will automatically be
- * seen as the directory going away, and the filename being created.
- *
- * Think of this as a three-way diff.
- *
- * The output will be either:
- *  - successful merge
- *	 "0 mode sha1 filename"
- *    NOTE NOTE NOTE! FIXME! We really really need to walk the index
- *    in parallel with this too!
- *
- *  - conflict:
- *	"1 mode sha1 filename"
- *	"2 mode sha1 filename"
- *	"3 mode sha1 filename"
- *    where not all of the 1/2/3 lines may exist, of course.
- *
- * The successful merge rules are the same as for the three-way merge
- * in git-read-tree.

+Close the C<PIPE_IN> and C<PIPE_OUT> as returned from C<command_bidi_pipe()>,
+checking whether the command finished successfully. The optional C<CTX>
+argument is required if you want to see the command name in the error message,
+and it is the fourth value returned by C<command_bidi_pipe()>.  The call idiom
+is:
+
+	my ($pid, $in, $out, $ctx) = $r->command_bidi_pipe('cat-file --batch-check');
+	print $out "000000000\n";
+	while (<$in>) { ... }

+
+Note that you should not rely on whatever actually is in C<CTX>;
+currently it is simply the command name but in future the context might
+have more complicated structure.
+
+C<PIPE_IN> and C<PIPE_OUT> may be C<undef> if they have been closed prior to
+calling this function.  This may be useful in a query-response type of
+commands where caller first writes a query and later reads response, eg:
+
+	my ($pid, $in, $out, $ctx) = $r->command_bidi_pipe('cat-file --batch-check');
+	print $out "000000000\n";
+	close $out;
+	while (<$in>) { ... }
+	$r->command_close_bidi_pipe($pid, $in, undef, $ctx);

+=item credential( CREDENTIAL_HASHREF [, OPERATION ] )
+
+=item credential( CREDENTIAL_HASHREF, CODE )
+
+Executes C<git credential> for a given set of credentials and specified
+operation.  In both forms C<CREDENTIAL_HASHREF> needs to be a reference to
+a hash which stores credentials.  Under certain conditions the hash can
+change.
+
+In the first form, C<OPERATION> can be C<'fill'>, C<'approve'> or C<'reject'>,
+and function will execute corresponding C<git credential> sub-command.  If
+it's omitted C<'fill'> is assumed.  In case of C<'fill'> the values stored in
+C<CREDENTIAL_HASHREF> will be changed to the ones returned by the C<git
+credential fill> command.  The usual usage would look something like:
+
+	my %cred = (
+		'protocol' => 'https',
+		'host' => 'example.com',
+		'username' => 'bob'
+	);
+	Git::credential \%cred;
+	if (try_to_authenticate($cred{'username'}, $cred{'password'})) {
+		Git::credential \%cred, 'approve';
+		... do more stuff ...
+	} else {
+		Git::credential \%cred, 'reject';
+	}
+
+In the second form, C<CODE> needs to be a reference to a subroutine.  The
+function will execute C<git credential fill> to fill the provided credential
+hash, then call C<CODE> with C<CREDENTIAL_HASHREF> as the sole argument.  If
+C<CODE>'s return value is defined, the function will execute C<git credential
+approve> (if return value yields true) or C<git credential reject> (if return
+value is false).  If the return value is undef, nothing at all is executed;
+this is useful, for example, if the credential could neither be verified nor
+rejected due to an unrelated network error.  The return value is the same as
+what C<CODE> returns.  With this form, the usage might look as follows:
+
+	if (Git::credential {
+		'protocol' => 'https',
+		'host' => 'example.com',
+		'username' => 'bob'
+	}, sub {
+		my $cred = shift;

+to retrieve temporary files mapped to the same C<NAME> while still locked will

+threadsafe. It does provide some error checking to help prevent temp file refs
+writing over one another.
+
+In general, the L<File::Handle> returned should not be closed by consumers as
+it defeats the purpose of this caching mechanism. If you need to close the temp
+file handle, then you should use L<File::Temp> or another temp file faculty

+is called with either the original C<NAME> or the L<File::Handle> that was
+returned from the original call to temp_acquire.
+
+Subsequent attempts to call C<temp_acquire()> with the same C<NAME> will fail
+unless there has been an intervening C<temp_release()> call for that C<NAME>
+(or its corresponding L<File::Handle> that was returned by the original
+C<temp_acquire()> call).
+
+If true is returned by C<temp_is_locked()> for a C<NAME>, an attempt to
+C<temp_acquire()> the same C<NAME> will cause an error unless

+Git's internal Perl interface to gettext via L<Locale::Messages>. If
+L<Locale::Messages> can't be loaded (it's not a core module) we
+provide stub passthrough fallbacks.
+
+This is a distilled interface to gettext, see C<info '(gettext)Perl'>
+for the full interface. This module implements only a small part of
+it.
+
+=head1 FUNCTIONS
+
+=head2 __($)
+
+L<Locale::Messages>'s gettext function if all goes well, otherwise our
+passthrough fallback function.

+#
+# This is the replacement for the rev_db format, which was too big
+# and inefficient for large repositories with a lot of sparse history
+# (mainly tags)
+#
+# The format is this:
+#   - 24 bytes for every record,
+#     * 4 bytes for the integer representing an SVN revision number
+#     * 20 bytes representing the sha1 of a git commit
+#   - No empty padding records like the old format
+#     (except the last record, which can be overwritten)
+#   - new records are written append-only since SVN revision numbers
+#     increase monotonically
+#   - lookups on SVN revision number are done via a binary search
+#   - Piping the file to xxd -c24 is a good way of dumping it for
+#     viewing or editing (piped back through xxd -r), should the need
+#     ever arise.
+#   - The last record can be padding revision with an all-zero sha1
+#     This is used to optimize fetch performance when using multiple
+#     "fetch" directives in .git/config
+#
+# These files are disposable unless noMetadata or useSvmProps is set

+	use Git::SVN::Ra;
+
+	my $ra = Git::SVN::Ra->new($url);
+	my %opts = (
+		r => 19,

+
+=head1 DESCRIPTION
+
+This module is an implementation detail of the "git svn" command.
+Do not use it unless you are developing git-svn.
+
+This module adapts the C<SVN::Delta::Editor> object returned by
+C<SVN::Delta::get_commit_editor> and drives it to convey the
+difference between two git tree objects to a remote Subversion
+repository.
+
+The interface will change as git-svn evolves.
+
+=head1 DEPENDENCIES
+
+Subversion perl bindings,
+the core L<Carp> module,
+and git's L<Git> helper module.
+
+C<Git::SVN::Editor> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Delta>,
+L<Git::SVN::Fetcher>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+=head1 DESCRIPTION
+
+This is a subclass of C<SVN::Delta::Editor>, which means it implements
+callbacks to act as a consumer of Subversion tree deltas.  This
+particular implementation of those callbacks is meant to store
+information about the resulting content which B<git svn fetch> could
+use to populate new commits and new entries for F<unhandled.log>.
+More specifically:
+
+=over
+
+=item * Additions, removals, and modifications of files are propagated
+to git-svn's index file F<$GIT_DIR/svn/$refname/index> using
+B<git update-index>.
+
+=item * Changes in Subversion path properties are recorded in the
+C<dir_prop> and C<file_prop> fields (which are hashes).
+
+=item * Addition and removal of empty directories are indicated by
+entries with value 1 and 0 respectively in the C<empty> hash.
+
+=item * Paths that are present but cannot be conveyed (presumably due
+to permissions) are recorded in the C<absent_file> and
+C<absent_dirs> hashes.  For each key, the corresponding value is
+a list of paths under that directory that were present but
+could not be conveyed.
+
+=back
+
+The interface is unstable.  Do not use this module unless you are
+developing git-svn.
+
+=head1 DEPENDENCIES
+
+L<SVN::Delta> from the Subversion perl bindings,
+the core L<Carp> and L<File::Basename> modules,
+and git's L<Git> helper module.
+
+C<Git::SVN::Fetcher> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Delta>,
+L<Git::SVN::Editor>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+=head1 NAME
+
+Git::SVN::Memoize::YAML - store Memoized data in YAML format
+
+=head1 SYNOPSIS
+
+    use Memoize;
+    use Git::SVN::Memoize::YAML;
+
+    tie my %cache => 'Git::SVN::Memoize::YAML', $filename;
+    memoize('slow_function', SCALAR_CACHE => [HASH => \%cache]);
+    slow_function(arguments);
+
+=head1 DESCRIPTION
+
+This module provides a class that can be used to tie a hash to a
+YAML file.  The file is read when the hash is initialized and
+rewritten when the hash is destroyed.
+
+The intent is to allow L<Memoize> to back its cache with a file in
+YAML format, just like L<Memoize::Storable> allows L<Memoize> to
+back its cache with a file in Storable format.  Unlike the Storable
+format, the YAML format is platform-independent and fairly stable.
+
+Carps on error.
+
+=head1 DIAGNOSTICS
+
+See L<YAML::Any>.
+
+=head1 DEPENDENCIES
+
+L<YAML::Any> from CPAN.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+The entire cache is read into a Perl hash when loading the file,
+so this is not very scalable.

+
+Git::SVN::Ra - Subversion remote access functions for git-svn
+
+=head1 SYNOPSIS
+
+    use Git::SVN::Ra;
+
+    my $ra = Git::SVN::Ra->new($branchurl);
+    my ($dirents, $fetched_revnum, $props) =
+        $ra->get_dir('.', $SVN::Core::INVALID_REVNUM);
+
+=head1 DESCRIPTION
+
+This is a wrapper around the L<SVN::Ra> module for use by B<git-svn>.
+It fills in some default parameters (such as the authentication
+scheme), smooths over incompatibilities between libsvn versions, adds
+caching, and implements some functions specific to B<git-svn>.
+
+Do not use it unless you are developing git-svn.  The interface will
+change as git-svn evolves.
+
+=head1 DEPENDENCIES
+
+Subversion perl bindings,
+L<Git::SVN>.
+
+C<Git::SVN::Ra> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Ra>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+Core GIT Translations
+=====================
+
+This directory holds the translations for the core of Git. This document
+describes how you can contribute to the effort of enhancing the language
+coverage and maintaining the translation.
+
+The localization (l10n) coordinator, Jiang Xin <worldhello.net@gmail.com>,
+coordinates our localization effort in the l10 coordinator repository:
+
+        https://github.com/git-l10n/git-po/
+
+The two character language translation codes are defined by ISO_639-1, as
+stated in the gettext(1) full manual, appendix A.1, Usual Language Codes.
+
+
+Contributing to an existing translation
+---------------------------------------
+As a contributor for a language XX, you should first check TEAMS file in
+this directory to see whether a dedicated repository for your language XX
+exists. Fork the dedicated repository and start to work if it exists.
+
+Sometime, contributors may find that the translations of their Git
+distributions are quite different with the translations of the
+corresponding version from Git official. This is because some Git
+distributions (such as from Ubuntu, etc.) have their own l10n workflow.
+For this case, wrong translations should be reported and fixed through
+their workflows.
+
+
+Creating a new language translation
+-----------------------------------
+If you are the first contributor for the language XX, please fork this
+repository, prepare and/or update the translated message file po/XX.po
+(described later), and ask the l10n coordinator to pull your work.
+
+If there are multiple contributors for the same language, please first
+coordinate among yourselves and nominate the team leader for your
+language, so that the l10n coordinator only needs to interact with one
+person per language.
+
+
+Translation Process Flow
+------------------------
+The overall data-flow looks like this:
+
+    +-------------------+            +------------------+
+    | Git source code   | ---(1)---> | L10n coordinator |
+    | repository        | <---(4)--- | repository       |
+    +-------------------+            +------------------+
+                                          |      ^
+                                         (2)    (3)
+                                          V      |
+                                     +------------------+
+                                     | Language Team XX |
+                                     +------------------+
+
+ * Translatable strings are marked in the source file.
+ * L10n coordinator pulls from the source (1)
+ * L10n coordinator updates the message template po/git.pot
+ * Language team pulls from L10n coordinator (2)
+ * Language team updates the message file po/XX.po
+ * L10n coordinator pulls from Language team (3)
+ * L10n coordinator asks the result to be pulled (4).
+
+
+Maintaining the po/git.pot file
+-------------------------------
+
+(This is done by the l10n coordinator).
+
+The po/git.pot file contains a message catalog extracted from Git's
+sources. The l10n coordinator maintains it by adding new translations with
+msginit(1), or update existing ones with msgmerge(1).  In order to update
+the Git sources to extract the messages from, the l10n coordinator is
+expected to pull from the main git repository at strategic point in
+history (e.g. when a major release and release candidates are tagged),
+and then run "make pot" at the top-level directory.
+
+Language contributors use this file to prepare translations for their
+language, but they are not expected to modify it.
+
+
+Initializing a XX.po file
+-------------------------
+
+(This is done by the language teams).
+
+If your language XX does not have translated message file po/XX.po yet,
+you add a translation for the first time by running:
+
+    msginit --locale=XX
+
+in the po/ directory, where XX is the locale, e.g. "de", "is", "pt_BR",
+"zh_CN", etc.
+
+Then edit the automatically generated copyright info in your new XX.po
+to be correct, e.g. for Icelandic:
+
+    @@ -1,6 +1,6 @@
+    -# Icelandic translations for PACKAGE package.
+    -# Copyright (C) 2010 THE PACKAGE'S COPYRIGHT HOLDER
+    -# This file is distributed under the same license as the PACKAGE package.
+    +# Icelandic translations for Git.
+    +# Copyright (C) 2010 Ævar Arnfjörð Bjarmason <avarab@gmail.com>
+    +# This file is distributed under the same license as the Git package.
+     # Ævar Arnfjörð Bjarmason <avarab@gmail.com>, 2010.
+
+And change references to PACKAGE VERSION in the PO Header Entry to
+just "Git":
+
+    perl -pi -e 's/(?<="Project-Id-Version: )PACKAGE VERSION/Git/' XX.po
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Updating a XX.po file
+---------------------
+
+(This is done by the language teams).
+
+If you are replacing translation strings in an existing XX.po file to
+improve the translation, just edit the file.
+
+If there's an existing XX.po file for your language, but the repository
+of the l10n coordinator has newer po/git.pot file, you would need to first
+pull from the l10n coordinator (see the beginning of this document for its
+URL), and then update the existing translation by running:
+
+    msgmerge --add-location --backup=off -U XX.po git.pot
+
+in the po/ directory, where XX.po is the file you want to update.
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Testing your changes
+--------------------
+
+(This is done by the language teams, after creating or updating XX.po file).
+
+Before you submit your changes go back to the top-level and do:
+
+    make
+
+On systems with GNU gettext (i.e. not Solaris) this will compile your
+changed PO file with `msgfmt --check`, the --check option flags many
+common errors, e.g. missing printf format strings, or translated
+messages that deviate from the originals in whether they begin/end
+with a newline or not.
+
+
+Marking strings for translation
+-------------------------------
+
+(This is done by the core developers).
+
+Before strings can be translated they first have to be marked for
+translation.
+
+Git uses an internationalization interface that wraps the system's
+gettext library, so most of the advice in your gettext documentation
+(on GNU systems `info gettext` in a terminal) applies.
+
+General advice:
+
+ - Don't mark everything for translation, only strings which will be
+   read by humans (the porcelain interface) should be translated.
+
+   The output from Git's plumbing utilities will primarily be read by
+   programs and would break scripts under non-C locales if it was
+   translated. Plumbing strings should not be translated, since
+   they're part of Git's API.
+
+ - Adjust the strings so that they're easy to translate. Most of the
+   advice in `info '(gettext)Preparing Strings'` applies here.
+
+ - If something is unclear or ambiguous you can use a "TRANSLATORS"
+   comment to tell the translators what to make of it. These will be
+   extracted by xgettext(1) and put in the po/*.po files, e.g. from
+   git-am.sh:
+
+       # TRANSLATORS: Make sure to include [y], [n], [e], [v] and [a]
+       # in your translation. The program will only accept English
+       # input at this point.
+       gettext "Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all "
+
+   Or in C, from builtin/revert.c:
+
+       /* TRANSLATORS: %s will be "revert" or "cherry-pick" */
+       die(_("%s: Unable to write new index file"), action_name(opts));
+
+We provide wrappers for C, Shell and Perl programs. Here's how they're
+used:
+
+C:
+
+ - Include builtin.h at the top, it'll pull in gettext.h, which
+   defines the gettext interface. Consult with the list if you need to
+   use gettext.h directly.
+
+ - The C interface is a subset of the normal GNU gettext
+   interface. We currently export these functions:
+
+   - _()
+
+    Mark and translate a string. E.g.:
+
+        printf(_("HEAD is now at %s"), hex);
+
+   - Q_()
+
+    Mark and translate a plural string. E.g.:
+
+        printf(Q_("%d commit", "%d commits", number_of_commits));
+
+    This is just a wrapper for the ngettext() function.
+
+   - N_()
+
+    A no-op pass-through macro for marking strings inside static
+    initializations, e.g.:
+
+        static const char *reset_type_names[] = {
+            N_("mixed"), N_("soft"), N_("hard"), N_("merge"), N_("keep"), NULL
+        };
+
+    And then, later:
+
+        die(_("%s reset is not allowed in a bare repository"),
+               _(reset_type_names[reset_type]));
+
+    Here _() couldn't have statically determined what the translation
+    string will be, but since it was already marked for translation
+    with N_() the look-up in the message catalog will succeed.
+
+Shell:
+
+ - The Git gettext shell interface is just a wrapper for
+   gettext.sh. Import it right after git-sh-setup like this:
+
+       . git-sh-setup
+       . git-sh-i18n
+
+   And then use the gettext or eval_gettext functions:
+
+       # For constant interface messages:
+       gettext "A message for the user"; echo
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettext "An error occurred: \$details"; echo
+
+   In addition we have wrappers for messages that end with a trailing
+   newline. I.e. you could write the above as:
+
+       # For constant interface messages:
+       gettextln "A message for the user"
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettextln "An error occurred: \$details"
+
+   More documentation about the interface is available in the GNU info
+   page: `info '(gettext)sh'`. Looking at git-am.sh (the first shell
+   command to be translated) for examples is also useful:
+
+       git log --reverse -p --grep=i18n git-am.sh
+
+Perl:
+
+ - The Git::I18N module provides a limited subset of the
+   Locale::Messages functionality, e.g.:
+
+       use Git::I18N;
+       print __("Welcome to Git!\n");
+       printf __("The following error occurred: %s\n"), $error;
+
+   Run `perldoc perl/Git/I18N.pm` for more info.
+
+
+Testing marked strings
+----------------------
+
+Even if you've correctly marked porcelain strings for translation
+something in the test suite might still depend on the US English
+version of the strings, e.g. to grep some error message or other
+output.
+
+To smoke out issues like these Git can be compiled with gettext poison
+support, at the top-level:
+
+    make GETTEXT_POISON=YesPlease
+
+That'll give you a git which emits gibberish on every call to
+gettext. It's obviously not meant to be installed, but you should run
+the test suite with it:
+
+    cd t && prove -j 9 ./t[0-9]*.sh
+
+If tests break with it you should inspect them manually and see if
+what you're translating is sane, i.e. that you're not translating
+plumbing output.
+
+If not you should replace calls to grep with test_i18ngrep, or
+test_cmp calls with test_i18ncmp. If that's not enough you can skip
+the whole test by making it depend on the C_LOCALE_OUTPUT
+prerequisite. See existing test files with this prerequisite for
+examples.

+ * If the reference cannot be resolved to an object, the behavior

+ * - If RESOLVE_REF_READING is set, return NULL.
+ *
+ * - If RESOLVE_REF_READING is not set, clear sha1 and return the name of

+ *   reference or an undefined reference.  If this is a prelude to
+ *   "writing" to the ref, the return value is the name of the ref
+ *   that will actually be created or changed.
+ *
+ * If the RESOLVE_REF_NO_RECURSE flag is passed, only resolves one
+ * level of symbolic reference.  The value stored in sha1 for a symbolic
+ * reference will always be null_sha1 in this case, and the return
+ * value is the reference that the symref refers to directly.
+ *
+ * If flags is non-NULL, set the value that it points to the
+ * combination of REF_ISPACKED (if the reference was found among the
+ * packed references), REF_ISSYMREF (if the initial reference was a
+ * symbolic reference), REF_BAD_NAME (if the reference name is ill
+ * formed --- see RESOLVE_REF_ALLOW_BAD_NAME below), and REF_ISBROKEN
+ * (if the ref is malformed or has a bad name). See refs.h for more detail
+ * on each flag.
+ *
+ * If ref is not a properly-formatted, normalized reference, return
+ * NULL.  If more than MAXDEPTH recursive symbolic lookups are needed,
+ * give up and return NULL.
+ *
+ * RESOLVE_REF_ALLOW_BAD_NAME allows resolving refs even when their
+ * name is invalid according to git-check-ref-format(1).  If the name
+ * is bad then the value stored in sha1 will be null_sha1 and the two
+ * flags REF_ISBROKEN and REF_BAD_NAME will be set.
+ *
+ * Even with RESOLVE_REF_ALLOW_BAD_NAME, names that escape the refs/
+ * directory and do not consist of all caps and underscores cannot be

+	 *
+	 * Default log would produce "I" by following the first parent;
+	 * --full-history --simplify-merges will produce "I-A-B". But this is a

+/**
+ * strbuf's are meant to be used with all the usual C string and memory
+ * APIs. Given that the length of the buffer is known, it's often better to
+ * use the mem* functions than a str* one (memchr vs. strchr e.g.).
+ * Though, one has to be careful about the fact that str* functions often
+ * stop on NULs and that strbufs may have embedded NULs.
+ *
+ * A strbuf is NUL terminated for convenience, but no function in the
+ * strbuf API actually relies on the string being free of NULs.
+ *
+ * strbufs have some invariants that are very important to keep in mind:
+ *
+ *  - The `buf` member is never NULL, so it can be used in any usual C
+ *    string operations safely. strbuf's _have_ to be initialized either by
+ *    `strbuf_init()` or by `= STRBUF_INIT` before the invariants, though.
+ *
+ *    Do *not* assume anything on what `buf` really is (e.g. if it is
+ *    allocated memory or not), use `strbuf_detach()` to unwrap a memory
+ *    buffer from its strbuf shell in a safe way. That is the sole supported
+ *    way. This will give you a malloced buffer that you can later `free()`.
+ *
+ *    However, it is totally safe to modify anything in the string pointed by
+ *    the `buf` member, between the indices `0` and `len-1` (inclusive).
+ *
+ *  - The `buf` member is a byte array that has at least `len + 1` bytes
+ *    allocated. The extra byte is used to store a `'\0'`, allowing the
+ *    `buf` member to be a valid C-string. Every strbuf function ensure this
+ *    invariant is preserved.
+ *
+ *    NOTE: It is OK to "play" with the buffer directly if you work it this
+ *    way:
+ *
+ *        strbuf_grow(sb, SOME_SIZE); <1>
+ *        strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE);
+ *
+ *    <1> Here, the memory array starting at `sb->buf`, and of length
+ *    `strbuf_avail(sb)` is all yours, and you can be sure that
+ *    `strbuf_avail(sb)` is at least `SOME_SIZE`.
+ *
+ *    NOTE: `SOME_OTHER_SIZE` must be smaller or equal to `strbuf_avail(sb)`.
+ *
+ *    Doing so is safe, though if it has to be done in many places, adding the
+ *    missing API to the strbuf module is the way to go.
+ *
+ *    WARNING: Do _not_ assume that the area that is yours is of size `alloc
+ *    - 1` even if it's true in the current implementation. Alloc is somehow a
+ *    "private" member that should not be messed with. Use `strbuf_avail()`
+ *    instead.

+
+prove and other harnesses come with a lot of useful options. The
+--state option in particular is very useful:
+
+    # Repeat until no more failures
+    $ prove -j 15 --state=failed,save ./t[0-9]*.sh
+
+You can give DEFAULT_TEST_TARGET=prove on the make command (or define it
+in config.mak) to cause "make test" to run tests under prove.
+GIT_PROVE_OPTS can be used to pass additional options, e.g.
+
+    $ make DEFAULT_TEST_TARGET=prove GIT_PROVE_OPTS='--timer --jobs 16' test
+
+You can also run each test individually from command line, like this:
+
+    $ sh ./t3010-ls-files-killed-modified.sh
+    ok 1 - git update-index --add to add various paths.

+    1..5
 
 You can pass --verbose (or -v), --debug (or -d), and --immediate
-(or -i) command line argument to the test.
+(or -i) command line argument to the test, or by setting GIT_TEST_OPTS
+appropriately before running "make".
 
+-v::
 --verbose::
 	This makes the test more verbose.  Specifically, the
 	command being run and their output if any are also
 	output.
 
+--verbose-only=<pattern>::
+	Like --verbose, but the effect is limited to tests with
+	numbers matching <pattern>.  The number matched against is
+	simply the running count of the test within the file.
+
+-x::
+	Turn on shell tracing (i.e., `set -x`) during the tests
+	themselves. Implies `--verbose`. Note that this can cause
+	failures in some tests which redirect and test the
+	output of shell functions. Use with caution.
+
+-d::
 --debug::
 	This may help the person who is developing a new test.
 	It causes the command defined with test_debug to run.
+	The "trash" directory (used to store all temporary data
+	during testing) is not deleted even if there are no
+	failed tests so that you can inspect its contents after
+	the test finished.
 
+-i::
 --immediate::
 	This causes the test to immediately exit upon the first
-	failed test.
+	failed test. Cleanup commands requested with
+	test_when_finished are not executed if the test failed,
+	in order to keep the state for inspection by the tester
+	to diagnose the bug.
+
+-l::
+--long-tests::
+	This causes additional long-running tests to be run (where
+	available), for more exhaustive testing.
+
+-r::
+--run=<test-selector>::
+	Run only the subset of tests indicated by
+	<test-selector>.  See section "Skipping Tests" below for
+	<test-selector> syntax.
+
+--valgrind=<tool>::
+	Execute all Git binaries under valgrind tool <tool> and exit
+	with status 126 on errors (just like regular tests, this will
+	only stop the test script when running under -i).
+
+	Since it makes no sense to run the tests with --valgrind and
+	not see any output, this option implies --verbose.  For
+	convenience, it also implies --tee.
+
+	<tool> defaults to 'memcheck', just like valgrind itself.
+	Other particularly useful choices include 'helgrind' and
+	'drd', but you may use any tool recognized by your valgrind
+	installation.
+
+	As a special case, <tool> can be 'memcheck-fast', which uses
+	memcheck but disables --track-origins.  Use this if you are
+	running tests in bulk, to see if there are _any_ memory
+	issues.
+
+	Note that memcheck is run with the option --leak-check=no,
+	as the git process is short-lived and some errors are not
+	interesting. In order to run a single command under the same
+	conditions manually, you should set GIT_VALGRIND to point to
+	the 't/valgrind/' directory and use the commands under
+	't/valgrind/bin/'.
+
+--valgrind-only=<pattern>::
+	Like --valgrind, but the effect is limited to tests with
+	numbers matching <pattern>.  The number matched against is
+	simply the running count of the test within the file.
+
+--tee::
+	In addition to printing the test output to the terminal,
+	write it to files named 't/test-results/$TEST_NAME.out'.
+	As the names depend on the tests' file names, it is safe to
+	run the tests with this option in parallel.
+
+--with-dashes::
+	By default tests are run without dashed forms of
+	commands (like git-commit) in the PATH (it only uses
+	wrappers from ../bin-wrappers).  Use this option to include
+	the build directory (..) in the PATH, which contains all
+	the dashed forms of commands.  This option is currently
+	implied by other options like --valgrind and
+	GIT_TEST_INSTALLED.
+
+--root=<directory>::
+	Create "trash" directories used to store all temporary data during
+	testing under <directory>, instead of the t/ directory.
+	Using this option with a RAM-based filesystem (such as tmpfs)
+	can massively speed up the test suite.
+
+--chain-lint::
+--no-chain-lint::
+	If --chain-lint is enabled, the test harness will check each
+	test to make sure that it properly "&&-chains" all commands (so
+	that a failure in the middle does not go unnoticed by the final
+	exit code of the test). This check is performed in addition to
+	running the tests themselves. You may also enable or disable
+	this feature by setting the GIT_TEST_CHAIN_LINT environment
+	variable to "1" or "0", respectively.
+
+You can also set the GIT_TEST_INSTALLED environment variable to
+the bindir of an existing git installation to test that installation.
+You still need to have built this git sandbox, from which various
+test-* support programs, templates, and perl libraries are used.
+If your installed git is incomplete, it will silently test parts of
+your built version instead.
+
+When using GIT_TEST_INSTALLED, you can also set GIT_TEST_EXEC_PATH to
+override the location of the dashed-form subcommands (what
+GIT_EXEC_PATH would be used for during normal operation).
+GIT_TEST_EXEC_PATH defaults to `$GIT_TEST_INSTALLED/git --exec-path`.
+
+
+Skipping Tests
+--------------
+
+In some environments, certain tests have no way of succeeding
+due to platform limitation, such as lack of 'unzip' program, or
+filesystem that do not allow arbitrary sequence of non-NUL bytes
+as pathnames.
+
+You should be able to say something like
+
+    $ GIT_SKIP_TESTS=t9200.8 sh ./t9200-git-cvsexport-commit.sh
+
+and even:
+
+    $ GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' make
+
+to omit such tests.  The value of the environment variable is a
+SP separated list of patterns that tells which tests to skip,
+and either can match the "t[0-9]{4}" part to skip the whole
+test, or t[0-9]{4} followed by ".$number" to say which
+particular test to skip.
+
+For an individual test suite --run could be used to specify that
+only some tests should be run or that some tests should be
+excluded from a run.
+
+The argument for --run is a list of individual test numbers or
+ranges with an optional negation prefix that define what tests in
+a test suite to include in the run.  A range is two numbers
+separated with a dash and matches a range of tests with both ends
+been included.  You may omit the first or the second number to
+mean "from the first test" or "up to the very last test"
+respectively.
+
+Optional prefix of '!' means that the test or a range of tests
+should be excluded from the run.
+
+If --run starts with an unprefixed number or range the initial
+set of tests to run is empty. If the first item starts with '!'
+all the tests are added to the initial set.  After initial set is
+determined every test number or range is added or excluded from
+the set one by one, from left to right.
+
+Individual numbers or ranges could be separated either by a space
+or a comma.
+
+For example, to run only tests up to a specific test (21), one
+could do this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='1-21'
+
+or this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='-21'
+
+Common case is to run several setup tests (1, 2, 3) and then a
+specific test (21) that relies on that setup:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='1 2 3 21'
+
+or:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run=1,2,3,21
+
+or:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='-3 21'
+
+As noted above, the test set is built going though items left to
+right, so this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='1-4 !3'
+
+will run tests 1, 2, and 4.  Items that comes later have higher
+precendence.  It means that this:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='!3 1-4'
+
+would just run tests from 1 to 4, including 3.
+
+You may use negation with ranges.  The following will run all
+test in the test suite except from 7 up to 11:
+
+    $ sh ./t9200-git-cvsexport-commit.sh --run='!7-11'
+
+Some tests in a test suite rely on the previous tests performing
+certain actions, specifically some tests are designated as
+"setup" test, so you cannot _arbitrarily_ disable one test and
+expect the rest to function correctly.
+
+--run is mostly useful when you want to focus on a specific test
+and know what setup is needed for it.  Or when you want to run
+everything up to a certain test.

+Do's, don'ts & things to keep in mind
+-------------------------------------
+
+Here are a few examples of things you probably should and shouldn't do
+when writing tests.
+
+Do:
+
+ - Put all code inside test_expect_success and other assertions.
+
+   Even code that isn't a test per se, but merely some setup code
+   should be inside a test assertion.
+
+ - Chain your test assertions
+
+   Write test code like this:
+
+	git merge foo &&
+	git push bar &&
+	test ...
+
+   Instead of:
+
+	git merge hla
+	git push gh
+	test ...
+
+   That way all of the commands in your tests will succeed or fail. If
+   you must ignore the return value of something, consider using a
+   helper function (e.g. use sane_unset instead of unset, in order
+   to avoid unportable return value for unsetting a variable that was
+   already unset), or prepending the command with test_might_fail or
+   test_must_fail.
+
+ - Check the test coverage for your tests. See the "Test coverage"
+   below.
+
+   Don't blindly follow test coverage metrics; if a new function you added
+   doesn't have any coverage, then you're probably doing something wrong,
+   but having 100% coverage doesn't necessarily mean that you tested
+   everything.
+
+   Tests that are likely to smoke out future regressions are better
+   than tests that just inflate the coverage metrics.
+
+ - When a test checks for an absolute path that a git command generated,
+   construct the expected value using $(pwd) rather than $PWD,
+   $TEST_DIRECTORY, or $TRASH_DIRECTORY. It makes a difference on
+   Windows, where the shell (MSYS bash) mangles absolute path names.
+   For details, see the commit message of 4114156ae9.
+
+Don't:
+
+ - exit() within a <script> part.
+
+   The harness will catch this as a programming error of the test.
+   Use test_done instead if you need to stop the tests early (see
+   "Skipping tests" below).
+
+ - use '! git cmd' when you want to make sure the git command exits
+   with failure in a controlled way by calling "die()".  Instead,
+   use 'test_must_fail git cmd'.  This will signal a failure if git
+   dies in an unexpected way (e.g. segfault).
+
+   On the other hand, don't use test_must_fail for running regular
+   platform commands; just use '! cmd'.  We are not in the business
+   of verifying that the world given to us sanely works.
+
+ - use perl without spelling it as "$PERL_PATH". This is to help our
+   friends on Windows where the platform Perl often adds CR before
+   the end of line, and they bundle Git with a version of Perl that
+   does not do so, whose path is specified with $PERL_PATH. Note that we
+   provide a "perl" function which uses $PERL_PATH under the hood, so
+   you do not need to worry when simply running perl in the test scripts
+   (but you do, for example, on a shebang line or in a sub script
+   created via "write_script").
+
+ - use sh without spelling it as "$SHELL_PATH", when the script can
+   be misinterpreted by broken platform shell (e.g. Solaris).
+
+ - chdir around in tests.  It is not sufficient to chdir to
+   somewhere and then chdir back to the original location later in
+   the test, as any intermediate step can fail and abort the test,
+   causing the next test to start in an unexpected directory.  Do so
+   inside a subshell if necessary.
+
+ - Break the TAP output
+
+   The raw output from your test may be interpreted by a TAP harness. TAP
+   harnesses will ignore everything they don't know about, but don't step
+   on their toes in these areas:
+
+   - Don't print lines like "$x..$y" where $x and $y are integers.
+
+   - Don't print lines that begin with "ok" or "not ok".
+
+   TAP harnesses expect a line that begins with either "ok" and "not
+   ok" to signal a test passed or failed (and our harness already
+   produces such lines), so your script shouldn't emit such lines to
+   their output.
+
+   You can glean some further possible issues from the TAP grammar
+   (see http://search.cpan.org/perldoc?TAP::Parser::Grammar#TAP_Grammar)
+   but the best indication is to just run the tests with prove(1),
+   it'll complain if anything is amiss.
+
+Keep in mind:
+
+ - Inside <script> part, the standard output and standard error
+   streams are discarded, and the test harness only reports "ok" or
+   "not ok" to the end user running the tests. Under --verbose, they
+   are shown to help debugging the tests.
+
+
+Skipping tests
+--------------
+
+If you need to skip tests you should do so by using the three-arg form
+of the test_* functions (see the "Test harness library" section
+below), e.g.:
+
+    test_expect_success PERL 'I need Perl' '
+        perl -e "hlagh() if unf_unf()"
+    '
+
+The advantage of skipping tests like this is that platforms that don't
+have the PERL and other optional dependencies get an indication of how
+many tests they're missing.
+
+If the test code is too hairy for that (i.e. does a lot of setup work
+outside test assertions) you can also skip all remaining tests by
+setting skip_all and immediately call test_done:
+
+	if ! test_have_prereq PERL
+	then
+	    skip_all='skipping perl interface tests, perl not available'
+	    test_done
+	fi
+
+The string you give to skip_all will be used as an explanation for why
+the test was skipped.

+ - test_commit <message> [<filename> [<contents>]]
+
+   Creates a commit with the given message, committing the given

+   all the tests if we don't have some essential prerequisite:
+
+	if ! test_have_prereq PERL

+	test_external \

+
+	test_expect_success 'Merge with d/f conflicts' '
+		test_expect_code 1 git merge "merge msg" B master
+	'
+
+ - test_must_fail <git-command>
+
+   Run a git command and ensure it fails in a controlled way.  Use
+   this instead of "! <git-command>".  When git-command dies due to a
+   segfault, test_must_fail diagnoses it as an error; "! <git-command>"
+   treats it as just another expected failure, which would let such a
+   bug go unnoticed.
+
+ - test_might_fail <git-command>
+
+   Similar to test_must_fail, but tolerate success, too.  Use this
+   instead of "<git-command> || :" to catch failures due to segv.
+
+ - test_cmp <expected> <actual>
+
+   Check whether the content of the <actual> file matches the
+   <expected> file.  This behaves like "cmp" but produces more
+   helpful output when the test is run with "-v" option.
+
+ - test_line_count (= | -lt | -ge | ...) <length> <file>
+
+   Check whether a file has the length it is expected to.
+
+ - test_path_is_file <path> [<diagnosis>]
+   test_path_is_dir <path> [<diagnosis>]
+   test_path_is_missing <path> [<diagnosis>]
+
+   Check if the named path is a file, if the named path is a
+   directory, or if the named path does not exist, respectively,
+   and fail otherwise, showing the <diagnosis> text.
+
+ - test_when_finished <script>
+
+   Prepend <script> to a list of commands to run to clean up
+   at the end of the current test.  If some clean-up command
+   fails, the test will not pass.
+
+   Example:
+
+	test_expect_success 'branch pointing to non-commit' '
+		git rev-parse HEAD^{tree} >.git/refs/heads/invalid &&
+		test_when_finished "git update-ref -d refs/heads/invalid" &&
+		...
+	'
+
+ - test_write_lines <lines>
+
+   Write <lines> on standard output, one line per argument.
+   Useful to prepare multi-line files in a compact form.
+
+   Example:
+
+	test_write_lines a b c d e f g >foo
+
+   Is a more compact equivalent of:
+	cat >foo <<-EOF
+	a
+	b
+	c
+	d
+	e
+	f
+	g
+	EOF
+
+
+ - test_pause
+
+	This command is useful for writing and debugging tests and must be
+	removed before submitting. It halts the execution of the test and
+	spawns a shell in the trash directory. Exit the shell to continue
+	the test. Example:
+
+	test_expect_success 'test' '
+		git do-something >actual &&
+		test_pause &&
+		test_cmp expected actual
+	'
+
+ - test_ln_s_add <path1> <path2>
+
+   This function helps systems whose filesystem does not support symbolic
+   links. Use it to add a symbolic link entry to the index when it is not
+   important that the file system entry is a symbolic link, i.e., instead
+   of the sequence
+
+	ln -s foo bar &&
+	git add bar
+
+   Sometimes it is possible to split a test in a part that does not need
+   the symbolic link in the file system and a part that does; then only
+   the latter part need be protected by a SYMLINKS prerequisite (see below).
+
+Prerequisites
+-------------
+
+These are the prerequisites that the test library predefines with
+test_have_prereq.
+
+See the prereq argument to the test_* functions in the "Test harness
+library" section above and the "test_have_prereq" function for how to
+use these, and "test_set_prereq" for how to define your own.
+
+ - PYTHON
+
+   Git wasn't compiled with NO_PYTHON=YesPlease. Wrap any tests that
+   need Python with this.
+
+ - PERL
+
+   Git wasn't compiled with NO_PERL=YesPlease.
+
+   Even without the PERL prerequisite, tests can assume there is a
+   usable perl interpreter at $PERL_PATH, though it need not be
+   particularly modern.
+
+ - POSIXPERM
+
+   The filesystem supports POSIX style permission bits.
+
+ - BSLASHPSPEC
+
+   Backslashes in pathspec are not directory separators. This is not
+   set on Windows. See 6fd1106a for details.
+
+ - EXECKEEPSPID
+
+   The process retains the same pid across exec(2). See fb9a2bea for
+   details.
+
+ - PIPE
+
+   The filesystem we're on supports creation of FIFOs (named pipes)
+   via mkfifo(1).
+
+ - SYMLINKS
+
+   The filesystem we're on supports symbolic links. E.g. a FAT
+   filesystem doesn't support these. See 704a3143 for details.
+
+ - SANITY
+
+   Test is not run by root user, and an attempt to write to an
+   unwritable file is expected to fail correctly.
+
+ - LIBPCRE
+
+   Git was compiled with USE_LIBPCRE=YesPlease. Wrap any tests
+   that use git-grep --perl-regexp or git-grep -P in these.
+
+ - CASE_INSENSITIVE_FS
+
+   Test is run on a case insensitive file system.
+
+ - UTF8_NFD_TO_NFC
+
+   Test is run on a filesystem which converts decomposed utf-8 (nfd)
+   to precomposed utf-8 (nfc).
 
 Tips for Writing Tests
 ----------------------
@@ -209,3 +830,42 @@ the purpose of t0000-basic.sh, which is to isolate that level of
 validation in one place.  Your test also ends up needing
 updating when such a change to the internal happens, so do _not_
 do it and leave the low level of validation to t0000-basic.sh.
+
+Test coverage
+-------------
+
+You can use the coverage tests to find code paths that are not being
+used or properly exercised yet.
+
+To do that, run the coverage target at the top-level (not in the t/
+directory):
+
+    make coverage
+
+That'll compile Git with GCC's coverage arguments, and generate a test
+report with gcov after the tests finish. Running the coverage tests
+can take a while, since running the tests in parallel is incompatible
+with GCC's coverage mode.
+
+After the tests have run you can generate a list of untested
+functions:
+
+    make coverage-untested-functions
+
+You can also generate a detailed per-file HTML report using the
+Devel::Cover module. To install it do:
+
+   # On Debian or Ubuntu:
+   sudo aptitude install libdevel-cover-perl
+
+   # From the CPAN with cpanminus
+   curl -L http://cpanmin.us | perl - --sudo --self-upgrade
+   cpanm --sudo Devel::Cover
+
+Then, at the top-level:
+
+    make cover_db_html
+
+That'll generate a detailed cover report in the "cover_db_html"
+directory, which you can then copy to a webserver, or inspect locally
+in a browser.

+
+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+Git is an Open Source project covered by the GNU General Public License.
+It was originally written by Linus Torvalds with help of a group of

+
+Please read the file INSTALL for installation instructions.
+See Documentation/tutorial.txt to get started, then see
+Documentation/everyday.txt for a useful minimum set of commands,

+CVS users may also want to read Documentation/cvs-migration.txt.
+
+Many Git online resources are accessible from http://git.or.cz/
+including full documentation and Git related tools.
+
+The user discussion and development of Git take place on the Git

+
+The messages titled "A note from the maintainer", "What's in
+git.git (stable)" and "What's cooking in git.git (topics)" and
+the discussion following them on the mailing list give a good

+Git performance tests
+=====================
+
+This directory holds performance testing scripts for git tools.  The
+first part of this document describes the various ways in which you
+can run them.
+
+When fixing the tools or adding enhancements, you are strongly
+encouraged to add tests in this directory to cover what you are
+trying to fix or enhance.  The later part of this short document
+describes how your test scripts should be organized.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make".  This runs all
+the tests on the current git repository.
+
+    === Running 2 tests in this tree ===
+    [...]
+    Test                                     this tree
+    ---------------------------------------------------------
+    0001.1: rev-list --all                   0.54(0.51+0.02)
+    0001.2: rev-list --all --objects         6.14(5.99+0.11)
+    7810.1: grep worktree, cheap regex       0.16(0.16+0.35)
+    7810.2: grep worktree, expensive regex   7.90(29.75+0.37)
+    7810.3: grep --cached, cheap regex       3.07(3.02+0.25)
+    7810.4: grep --cached, expensive regex   9.39(30.57+0.24)
+
+You can compare multiple repositories and even git revisions with the
+'run' script:
+
+    $ ./run . origin/next /path/to/git-tree p0001-rev-list.sh
+
+where . stands for the current git tree.  The full invocation is
+
+    ./run [<revision|directory>...] [--] [<test-script>...]
+
+A '.' argument is implied if you do not pass any other
+revisions/directories.
+
+You can also manually test this or another git build tree, and then
+call the aggregation script to summarize the results:
+
+    $ ./p0001-rev-list.sh
+    [...]
+    $ GIT_BUILD_DIR=/path/to/other/git ./p0001-rev-list.sh
+    [...]
+    $ ./aggregate.perl . /path/to/other/git ./p0001-rev-list.sh
+
+aggregate.perl has the same invocation as 'run', it just does not run
+anything beforehand.
+
+You can set the following variables (also in your config.mak):
+
+    GIT_PERF_REPEAT_COUNT
+	Number of times a test should be repeated for best-of-N
+	measurements.  Defaults to 3.
+
+    GIT_PERF_MAKE_OPTS
+	Options to use when automatically building a git tree for
+	performance testing.  E.g., -j6 would be useful.
+
+    GIT_PERF_REPO
+    GIT_PERF_LARGE_REPO
+	Repositories to copy for the performance tests.  The normal
+	repo should be at least git.git size.  The large repo should
+	probably be about linux.git size for optimal results.
+	Both default to the git.git you are running from.
+
+You can also pass the options taken by ordinary git tests; the most
+useful one is:
+
+--root=<directory>::
+	Create "trash" directories used to store all temporary data during
+	testing under <directory>, instead of the t/ directory.
+	Using this option with a RAM-based filesystem (such as tmpfs)
+	can massively speed up the test suite.
+
+
+Naming Tests
+------------
+
+The performance test files are named as:
+
+	pNNNN-commandname-details.sh
+
+where N is a decimal digit.  The same conventions for choosing NNNN as
+for normal tests apply.
+
+
+Writing Tests
+-------------
+
+The perf script starts much like a normal test script, except it
+sources perf-lib.sh:
+
+	#!/bin/sh
+	#
+	# Copyright (c) 2005 Junio C Hamano
+	#
+
+	test_description='xxx performance test'
+	. ./perf-lib.sh
+
+After that you will want to use some of the following:
+
+	test_perf_default_repo  # sets up a "normal" repository
+	test_perf_large_repo    # sets up a "large" repository
+
+	test_perf_default_repo sub  # ditto, in a subdir "sub"
+
+        test_checkout_worktree  # if you need the worktree too
+
+At least one of the first two is required!
+
+You can use test_expect_success as usual.  For actual performance
+tests, use
+
+	test_perf 'descriptive string' '
+		command1 &&
+		command2
+	'
+
+test_perf spawns a subshell, for lack of better options.  This means
+that
+
+* you _must_ export all variables that you need in the subshell
+
+* you _must_ flag all variables that you want to persist from the
+  subshell with 'test_export':
+
+	test_perf 'descriptive string' '
+		foo=$(git rev-parse HEAD) &&
+		test_export foo
+	'
+
+  The so-exported variables are automatically marked for export in the
+  shell executing the perf test.  For your convenience, test_export is
+  the same as export in the main shell.
+
+  This feature relies on a bit of magic using 'set' and 'source'.
+  While we have tried to make sure that it can cope with embedded
+  whitespace and other special characters, it will not work with
+  multi-line data.

+The url data files in this directory contain URLs with characters
+in the range 0x01-0x1f and 0x7f-0xff to test the proper normalization
+of unprintable characters.
+
+A select few characters in the 0x01-0x1f range are skipped to help
+avoid problems running the test itself.
+
+The urls are in test files in this directory rather than being
+embedded in the test script for portability.

+test_description='external credential helper tests
+
+This is a tool for authors of external helper tools to sanity-check
+their helpers. If you have written the "git-credential-foo" helper,
+you check it with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo t0303-credential-external.sh
+
+This assumes that your helper is capable of both storing and
+retrieving credentials (some helpers may be read-only, and they will
+fail these tests).
+
+Please note that the individual tests do not verify all of the
+preconditions themselves, but rather build on each other. A failing
+test means that tests later in the sequence can return false "OK"
+results.
+
+If your helper supports time-based expiration with a configurable
+timeout, you can test that feature with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo \
+       GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
+       t0303-credential-external.sh
+
+If your helper requires additional setup before the tests are started,
+you can set GIT_TEST_CREDENTIAL_HELPER_SETUP to a sequence of shell
+commands.

+test_description="Tests of cwd/prefix/worktree/gitdir setup in all cases
+
+A few rules for repo setup:
+
+1. GIT_DIR is relative to user's cwd. --git-dir is equivalent to
+   GIT_DIR.
+
+2. .git file is relative to parent directory. .git file is basically
+   symlink in disguise. The directory where .git file points to will
+   become new git_dir.
+
+3. core.worktree is relative to git_dir.
+
+4. GIT_WORK_TREE is relative to user's cwd. --work-tree is
+   equivalent to GIT_WORK_TREE.
+
+5. GIT_WORK_TREE/core.worktree was originally meant to work only if
+   GIT_DIR is set, but earlier git didn't enforce it, and some scripts
+   depend on the implementation that happened to first discover .git by
+   going up from the users $cwd and then using the specified working tree
+   that may or may not have any relation to where .git was found in.  This
+   historical behaviour must be kept.
+
+6. Effective GIT_WORK_TREE overrides core.worktree and core.bare
+
+7. Effective core.worktree conflicts with core.bare
+
+8. If GIT_DIR is set but neither worktree nor bare setting is given,
+   original cwd becomes worktree.
+
+9. If .git discovery is done inside a repo, the repo becomes a bare
+   repo. .git discovery is performed if GIT_DIR is not set.
+
+10. If no worktree is available, cwd remains unchanged, prefix is
+    NULL.
+
+11. When user's cwd is outside worktree, cwd remains unchanged,
+    prefix is NULL.

+	    Hope, he says, cherishes the soul of him who lives in
+	    justice and holiness and is the nurse of his age and the
+	    companion of his journey;--hope which is mightiest to sway
+	    the restless soul of man.
+
+	How admirable are his words!  And the great blessing of riches, I do
+	not say to every man, but to a good man, is, that he has had no
+	occasion to deceive or to defraud others, either intentionally or
+	unintentionally; and when he departs to the world below he is not in
+	any apprehension about offerings due to the gods or debts which he owes
+	to men.  Now to this peace of mind the possession of wealth greatly
+	contributes; and therefore I say, that, setting one thing against
+	another, of the many advantages which wealth has to give, to a man of
+	sense this is in my opinion the greatest.
+
+	Well said, Cephalus, I replied; but as concerning justice, what is
+	it?--to speak the truth and to pay your debts--no more than this?  And
+	even to this are there not exceptions?  Suppose that a friend when in
+	his right mind has deposited arms with me and he asks for them when he
+	is not in his right mind, ought I to give them back to him?  No one
+	would say that I ought or that I should be right in doing so, any more
+	than they would say that I ought always to speak the truth to one who
+	is in his condition.
+
+	You are quite right, he replied.
+
+	But then, I said, speaking the truth and paying your debts is not a
+	correct definition of justice.
+
+	CEPHALUS - SOCRATES - POLEMARCHUS
+
+	Quite correct, Socrates, if Simonides is to be believed, said
+	Polemarchus interposing.
+
+	I fear, said Cephalus, that I must go now, for I have to look after the
+	sacrifices, and I hand over the argument to Polemarchus and the company.

+LO, praise of the prowess of people-kings
+of spear-armed Danes, in days long sped,
+we have heard, and what honor the athelings won!
+Oft Scyld the Scefing from squadroned foes,
+from many a tribe, the mead-bench tore,
+awing the earls. Since erst he lay

+How to write RIGHT test cases
+=============================
+
+Insert the word "ChangeMe" (exactly this form) at a distance of
+at least two lines from the line that must appear in the hunk header.
+
+The text that must appear in the hunk header must contain the word
+"right", but in all upper-case, like in the title above.
+
+To mark a test case that highlights a malfunction, insert the word
+BROKEN in all lower-case somewhere in the file.
+
+This text is a bit twisted and out of order, but it is itself a
+test case for the default hunk header pattern. Know what you are doing
+if you change it.
+
+BTW, this tests that the head line goes to the hunk header, not the line
+of equal signs.

+#
+# There is a conflict merging B & C, but one of filename not of file
+# content.  Whoever created D and E chose specific resolutions for that

+# (Note that this can be accomplished by having the virtual merge base have
+# the merged contents of b and c stored in a file named a, which seems like
+# the most logical choice anyway.)
+#
+# Comment from Junio: I do not necessarily agree with the choice "a", but
+# it feels sound to say "B and C do not agree what the final pathname
+# should be, but we know this content was derived from the common A:a so we
+# use one path whose name is arbitrary in the virtual merge base X between
+# D and E" and then further let the rename detection to notice that that
+# arbitrary path gets renamed between X-D to "newname" and X-E also to
+# "newname" to resolve it as both sides renaming it to the same new
+# name. It is akin to what we do at the content level, i.e. "B and C do not
+# agree what the final contents should be, so we leave the conflict marker
+# but that may cancel out at the final merge stage".

+# This test covers the handling of objects which might have old
+# mtimes in the filesystem (because they were used previously)
+# and are just now becoming referenced again.
+#
+# We're going to do two things that are a little bit "fake" to
+# help make our simulation easier:
+#
+#   1. We'll turn off reflogs. You can still run into
+#      problems with reflogs on, but your objects
+#      don't get pruned until both the reflog expiration
+#      has passed on their references, _and_ they are out
+#      of prune's expiration period. Dropping reflogs
+#      means we only have to deal with one variable in our tests,
+#      but the results generalize.
+#
+#   2. We'll use a temporary index file to create our
+#      works-in-progress. Most workflows would mention
+#      referenced objects in the index, which prune takes
+#      into account. However, many operations don't. For
+#      example, a partial commit with "git commit foo"
+#      will use a temporary index. Or they may not need
+#      an index at all (e.g., creating a new commit
+#      to refer to an existing tree).

+There are three files foo/bar/baz, and the following graph illustrates the
+content of these files in each commit:

+
+Next, test git merge --abort with the following variables:
+- before/after successful merge (should fail when not in merge context)
+- with/without conflicts
+- clean/dirty index before merge
+- clean/dirty worktree before merge
+- dirty index before merge matches contents on remote branch

+#    or a last line with nothing but a space to log messages.
+#  - The latest cvs 1.12.x server sends +0000 timezone (with some hidden "MT"
+#    tagging in the protocol), and if cvs 1.12.x client sees the MT tags,
+#    it converts to local time zone.  git-cvsserver doesn't do the +0000
+#    or the MT tags...
+#  - The latest 1.12.x releases add a "commitid:" field on to the end of the
+#    "date:" line (after "lines:").  Maybe we could stick git's commit id
+#    in it?  Or does CVS expect a certain number of bits (too few for
+#    a full sha1)?
+#
+# Given the above, expect the following test to break if git-cvsserver's
+# log output is improved.  The test is just to ensure it doesn't
+# accidentally get worse.

+This repository is for testing the ability to group revisions
+correctly along tags and branches.  Here is its history:
+
+  1.  The initial import (revision 1.1 of everybody) created a
+      directory structure with a file named `default' in each dir:
+
+            ./
+              default
+              sub1/default
+                   subsubA/default
+                   subsubB/default
+              sub2/default
+                   subsubA/default
+              sub3/default
+
+  2.  Then tagged everyone with T_ALL_INITIAL_FILES.
+
+  3.  Then tagged everyone except sub1/subsubB/default with
+      T_ALL_INITIAL_FILES_BUT_ONE.
+
+  4.  Then created branch B_FROM_INITIALS on everyone.
+
+  5.  Then created branch B_FROM_INITIALS_BUT_ONE on everyone except
+      /sub1/subsubB/default.
+
+  6.  Then committed modifications to two files: sub3/default, and
+      sub1/subsubA/default.
+
+  7.  Then committed a modification to all 7 files.
+
+  8.  Then backdated sub3/default to revision 1.2, and
+      sub2/subsubA/default to revision 1.1, and tagged with T_MIXED.
+
+  9.  Same as 8, but tagged with -b to create branch B_MIXED.
+
+  10. Switched the working copy to B_MIXED, and added
+      sub2/branch_B_MIXED_only.  (That's why the RCS file is in
+      sub2/Attic/ -- it never existed on trunk.)
+
+  11. In one commit, modified default, sub1/default, and
+      sub2/subsubA/default, on branch B_MIXED.
+
+  12. Did "cvs up -A" on sub2/default, then in one commit, made a
+      change to sub2/default and sub2/branch_B_MIXED_only.  So this
+      commit should be spread between the branch and the trunk.
+
+  13. Do "cvs up -A" to get everyone back to trunk, then make a new
+      branch B_SPLIT on everyone except sub1/subsubB/default,v.
+
+  14. Switch to branch B_SPLIT (see sub1/subsubB/default disappear)
+      and commit a change that affects everyone except sub3/default.
+
+  15. An hour or so later, "cvs up -A" to get sub1/subsubB/default
+      back, then commit a change on that file, on trunk.  (It's
+      important that this change happened after the previous commits
+      on B_SPLIT.)
+
+  16. Branch sub1/subsubB/default to B_SPLIT, then "cvs up -r B_SPLIT"
+      to switch the whole working copy to the branch.
+
+  17. Commit a change on B_SPLIT, to sub1/subsubB/default and
+      sub3/default.

+/*
+ * State diagram and cleanup
+ * -------------------------
+ *
+ * If the program exits while a temporary file is active, we want to
+ * make sure that we remove it. This is done by remembering the active
+ * temporary files in a linked list, `tempfile_list`. An `atexit(3)`
+ * handler and a signal handler are registered, to clean up any active
+ * temporary files.
+ *
+ * Because the signal handler can run at any time, `tempfile_list` and
+ * the `tempfile` objects that comprise it must be kept in
+ * self-consistent states at all times.
+ *
+ * The possible states of a `tempfile` object are as follows:
+ *
+ * - Uninitialized. In this state the object's `on_list` field must be
+ *   zero but the rest of its contents need not be initialized. As
+ *   soon as the object is used in any way, it is irrevocably
+ *   registered in `tempfile_list`, and `on_list` is set.
+ *
+ * - Active, file open (after `create_tempfile()` or
+ *   `reopen_tempfile()`). In this state:
+ *
+ *   - the temporary file exists
+ *   - `active` is set
+ *   - `filename` holds the filename of the temporary file
+ *   - `fd` holds a file descriptor open for writing to it
+ *   - `fp` holds a pointer to an open `FILE` object if and only if
+ *     `fdopen_tempfile()` has been called on the object
+ *   - `owner` holds the PID of the process that created the file
+ *
+ * - Active, file closed (after successful `close_tempfile()`). Same
+ *   as the previous state, except that the temporary file is closed,
+ *   `fd` is -1, and `fp` is `NULL`.
+ *
+ * - Inactive (after `delete_tempfile()`, `rename_tempfile()`, a
+ *   failed attempt to create a temporary file, or a failed
+ *   `close_tempfile()`). In this state:
+ *
+ *   - `active` is unset
+ *   - `filename` is empty (usually, though there are transitory
+ *     states in which this condition doesn't hold). Client code should
+ *     *not* rely on the filename being empty in this state.
+ *   - `fd` is -1 and `fp` is `NULL`
+ *   - the object is left registered in the `tempfile_list`, and
+ *     `on_list` is set.
+ *
+ * A temporary file is owned by the process that created it. The
+ * `tempfile` has an `owner` field that records the owner's PID. This
+ * field is used to prevent a forked process from deleting a temporary
+ * file created by its parent.

+/*
+ * Handle temporary files.
+ *
+ * The tempfile API allows temporary files to be created, deleted, and
+ * atomically renamed. Temporary files that are still active when the
+ * program ends are cleaned up automatically. Lockfiles (see
+ * "lockfile.h") are built on top of this API.
+ *
+ *
+ * Calling sequence
+ * ----------------
+ *
+ * The caller:
+ *
+ * * Allocates a `struct tempfile` either as a static variable or on
+ *   the heap, initialized to zeros. Once you use the structure to
+ *   call `create_tempfile()`, it belongs to the tempfile subsystem
+ *   and its storage must remain valid throughout the life of the
+ *   program (i.e. you cannot use an on-stack variable to hold this
+ *   structure).
+ *
+ * * Attempts to create a temporary file by calling
+ *   `create_tempfile()`.
+ *
+ * * Writes new content to the file by either:
+ *
+ *   * writing to the file descriptor returned by `create_tempfile()`
+ *     (also available via `tempfile->fd`).
+ *
+ *   * calling `fdopen_tempfile()` to get a `FILE` pointer for the
+ *     open file and writing to the file using stdio.
+ *
+ * When finished writing, the caller can:
+ *
+ * * Close the file descriptor and remove the temporary file by
+ *   calling `delete_tempfile()`.
+ *
+ * * Close the temporary file and rename it atomically to a specified
+ *   filename by calling `rename_tempfile()`. This relinquishes
+ *   control of the file.
+ *
+ * * Close the file descriptor without removing or renaming the
+ *   temporary file by calling `close_tempfile()`, and later call
+ *   `delete_tempfile()` or `rename_tempfile()`.
+ *
+ * Even after the temporary file is renamed or deleted, the `tempfile`
+ * object must not be freed or altered by the caller. However, it may
+ * be reused; just pass it to another call of `create_tempfile()`.
+ *
+ * If the program exits before `rename_tempfile()` or
+ * `delete_tempfile()` is called, an `atexit(3)` handler will close
+ * and remove the temporary file.
+ *
+ * If you need to close the file descriptor yourself, do so by calling
+ * `close_tempfile()`. You should never call `close(2)` or `fclose(3)`
+ * yourself, otherwise the `struct tempfile` structure would still
+ * think that the file descriptor needs to be closed, and a later
+ * cleanup would result in duplicate calls to `close(2)`. Worse yet,
+ * if you close and then later open another file descriptor for a
+ * completely different purpose, then the unrelated file descriptor
+ * might get closed.
+ *
+ *
+ * Error handling
+ * --------------
+ *
+ * `create_tempfile()` returns a file descriptor on success or -1 on
+ * failure. On errors, `errno` describes the reason for failure.
+ *
+ * `delete_tempfile()`, `rename_tempfile()`, and `close_tempfile()`
+ * return 0 on success. On failure they set `errno` appropriately, do
+ * their best to delete the temporary file, and return -1.

+ *   s - template includes a suffix that is suffixlen characters long.
+ *
+ *   m - the temporary file should be created with the specified mode
+ *       (otherwise, the mode is set to 0600).
+ *
+ * None of these functions modify template. If the caller wants to
+ * know the (absolute) path of the file that was created, it can be

-################################################################
-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git-rev-list ^master ^topic next
-	git-rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git-rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

+################################################################
+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:
+
+		   o---o---o---o---o---o---o---o---o---o "next"
+		  /       /           /           /
+		 /   a---a---b A     /           /
+		/   /               /           /
+	       /   /   c---c---c---c B         /
+	      /   /   /             \         /
+	     /   /   /   b---b C     \       /
+	    /   /   /   /             \     /
+    ---o---o---o---o---o---o---o---o---o---o---o "master"
+
+
+A, B and C are topic branches.
+
+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.
+
+ * C has not merged to "next" at all.
+
+We would want to allow C to be rebased, refuse A, and encourage
+B to be deleted.
+
+To compute (1):
+
+	git rev-list ^master ^topic next
+	git rev-list ^master        next
+
+	if these match, topic has not merged in next at all.
+
+To compute (2):
+
+	git rev-list master..topic
+
+	if this is empty, it is fully merged to "master".

+ * at any time there could be 3 cases:
+ *
+ *	1)  t < p[imin];
+ *	2)  t > p[imin];

+line_buffer API
+===============
+
+The line_buffer library provides a convenient interface for
+mostly-line-oriented input.
+
+Each line is not permitted to exceed 10000 bytes.  The provided
+functions are not thread-safe or async-signal-safe, and like
+`fgets()`, they generally do not function correctly if interrupted
+by a signal without SA_RESTART set.
+
+Calling sequence
+----------------
+
+The calling program:
+
+ - initializes a `struct line_buffer` to LINE_BUFFER_INIT
+ - specifies a file to read with `buffer_init`
+ - processes input with `buffer_read_line`, `buffer_skip_bytes`,
+   and `buffer_copy_bytes`
+ - closes the file with `buffer_deinit`, perhaps to start over and
+   read another file.
+
+When finished, the caller can use `buffer_reset` to deallocate
+resources.
+
+Using temporary files
+---------------------
+
+Temporary files provide a place to store data that should not outlive
+the calling program.  A program
+
+ - initializes a `struct line_buffer` to LINE_BUFFER_INIT
+ - requests a temporary file with `buffer_tmpfile_init`
+ - acquires an output handle by calling `buffer_tmpfile_rewind`
+ - uses standard I/O functions like `fprintf` and `fwrite` to fill
+   the temporary file
+ - declares writing is over with `buffer_tmpfile_prepare_to_read`
+ - can re-read what was written with `buffer_read_line`,
+   `buffer_copy_bytes`, and so on
+ - can reuse the temporary file by calling `buffer_tmpfile_rewind`
+   again
+ - removes the temporary file with `buffer_deinit`, perhaps to
+   reuse the line_buffer for some other file.
+
+When finished, the calling program can use `buffer_reset` to deallocate
+resources.
+
+Functions
+---------
+
+`buffer_init`, `buffer_fdinit`::
+	Open the named file or file descriptor for input.
+	buffer_init(buf, NULL) prepares to read from stdin.
+	On failure, returns -1 (with errno indicating the nature
+	of the failure).
+
+`buffer_deinit`::
+	Stop reading from the current file (closing it unless
+	it was stdin).  Returns nonzero if `fclose` fails or
+	the error indicator was set.
+
+`buffer_read_line`::
+	Read a line and strip off the trailing newline.
+	On failure or end of file, returns NULL.
+
+`buffer_copy_bytes`::
+	Read `len` bytes of input and dump them to the standard output
+	stream.  Returns early for error or end of file.
+
+`buffer_skip_bytes`::
+	Discards `len` bytes from the input stream (stopping early
+	if necessary because of an error or eof).  Return value is
+	the number of bytes successfully read.
+
+`buffer_reset`::
+	Deallocates non-static buffers.
