+===============
+
+NAME
+----
+git-name-rev - Find symbolic names for given revs
+
+
+SYNOPSIS
+--------
+[verse]
+'git name-rev' [--tags] [--refs=<pattern>]
+	       ( --all | --stdin | <commit-ish>... )
+
+DESCRIPTION
+-----------
+Finds symbolic names suitable for human digestion for revisions given in any
+format parsable by 'git rev-parse'.
+
+
+OPTIONS
+-------
+
+--tags::
+	Do not use branch names, but only tags to name the commits
+
+--refs=<pattern>::
+	Only use refs whose names match a given shell pattern.  The pattern
+	can be one of branch name, tag name or fully qualified ref name. If
+	given multiple times, use refs whose names match any of the given shell
+	patterns. Use `--no-refs` to clear any previous ref patterns given.
+
+--exclude=<pattern>::
+	Do not use any ref whose name matches a given shell pattern. The
+	pattern can be one of branch name, tag name or fully qualified ref
+	name. If given multiple times, a ref will be excluded when it matches
+	any of the given patterns. When used together with --refs, a ref will
+	be used as a match only when it matches at least one --refs pattern and
+	does not match any --exclude patterns. Use `--no-exclude` to clear the
+	list of exclude patterns.
+
+--all::
+	List all commits reachable from all refs
+
+--stdin::
+	Transform stdin by substituting all the 40-character SHA-1
+	hexes (say $hex) with "$hex ($rev_name)".  When used with
+	--name-only, substitute with "$rev_name", omitting $hex
+	altogether.  Intended for the scripter's use.
+
+--name-only::
+	Instead of printing both the SHA-1 and the name, print only
+	the name.  If given with --tags the usual tag prefix of
+	"tags/" is also omitted from the name, matching the output
+	of `git-describe` more closely.
+
+--no-undefined::
+	Die with error code != 0 when a reference is undefined,
+	instead of printing `undefined`.
+
+--always::
+	Show uniquely abbreviated commit object as fallback.
+
+EXAMPLES
+--------
+
+Given a commit, find out where it is relative to the local refs. Say somebody
+wrote you about that fantastic commit 33db5f4d9027a10e477ccf054b2c1ab94f74c85a.
+Of course, you look into the commit, but that only tells you what happened, but
+not the context.
+
+Enter 'git name-rev':
+
+------------
+% git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a
+33db5f4d9027a10e477ccf054b2c1ab94f74c85a tags/v0.99~940
+------------
+
+Now you are wiser, because you know that it happened 940 revisions before v0.99.
+
+Another nice thing you can do is:
+
+------------
+% git log | git name-rev --stdin
