+git-show-branches-script(1)
+===========================
+v0.99.4, Aug 2005
+
+NAME
+----
+git-show-branches-script - Show branches and their commits.
+
+SYNOPSIS
+--------
+'git show-branches <reference>...'
+
+DESCRIPTION
+-----------
+Shows the head commits from the named <reference> (or all refs under
+$GIT_DIR/refs/heads), and displays concise list of commit logs
+to show their relationship semi-visually.
+
+OPTIONS
+-------
+<reference>::
+ Name of the reference under $GIT_DIR/refs/heads/.
+
+
+OUTPUT
+------
+Given N <references>, the first N lines are the one-line
+description from their commit message. The branch head that is
+pointed at by $GIT_DIR/HEAD is prefixed with an asterisk '*'
+character while other heads are prefixed with a '!' character.
+
+Following these N lines, one-line log for each commit is
+displayed, indented N places. If a commit is on the I-th
+branch, the I-th indentation character shows a '+' sign;
+otherwise it shows a space.
+
+The following example shows three branches, "pu", "master" and
+"rc":
+
+ * [pu] Add cheap local clone '-s' flag to git-clone-script
+ ! [master] Documentation updates.
+ ! [rc] Merge master into rc
+ + Add cheap local clone '-s' flag to git-clone-script
+ + Alternate object pool mechanism updates.
+ + Audit rev-parse users.
+ ++ Documentation updates.
+ + Merge master into rc
+ +++ [PATCH] plug memory leak in diff.c::diff_free_filepair()
+
+These three branches all forked from a common commit, "[PATCH]
+plug memory leak...", and "rc" has one commit ahead of it. The
+"master" branch has one different commit that is also shared by
+"pu" branch, and "pu" branch has three more commits on top of
+"master" branch.
