+#
+# 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

+Git::SVN::Editor - commit driver for "git svn set-tree" and dcommit

+=head1 SYNOPSIS

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

+ config => SVN::Core::config_get_config($svn_config_dir),

+
+=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> and L<IO::File> modules,
+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>, L<File::Basename>, and L<IO::File> 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.

+
+Git::SVN::Utils - utility functions used across Git::SVN
+
+=head1 SYNOPSIS
+
+ use Git::SVN::Utils qw(functions to import);
+
+=head1 DESCRIPTION
+
+This module contains functions which are useful across many different
+parts of Git::SVN. Mostly it's a place to put utility functions
+rather than duplicate the code or have classes grabbing at other
+classes.
+
+=head1 FUNCTIONS
+
+All functions can be imported only on request.
+
+=head3 fatal
+
+ fatal(@message);
+
+Display a message and exit with a fatal error code.
+
+=cut
+
+# Note: not certain why this is in use instead of die. Probably because
+# the exit code of die is 255? Doesn't appear to be used consistently.
+sub fatal (@) { print STDERR "@_\n"; exit 1 }

+
