+NAME
+----
+git-shortlog - Summarize 'git log' output
+
+SYNOPSIS
+--------
+[verse]
+'git shortlog' [<options>] [<revision-range>] [[--] <path>...]
+git log --pretty=short | 'git shortlog' [<options>]
+
+DESCRIPTION
+-----------
+Summarizes 'git log' output in a format suitable for inclusion
+in release announcements. Each commit will be grouped by author and title.
+
+Additionally, "[PATCH]" will be stripped from the commit description.
+
+If no revisions are passed on the command line and either standard input
+is not a terminal or there is no current branch, 'git shortlog' will
+output a summary of the log read from standard input, without
+reference to the current repository.
+
+OPTIONS
+-------
+
+-n::
+--numbered::
+	Sort output according to the number of commits per author instead
+	of author alphabetic order.
+
+-s::
+--summary::
+	Suppress commit description and provide a commit count summary only.
+
+-e::
+--email::
+	Show the email address of each author.
+
+--format[=<format>]::
+	Instead of the commit subject, use some other information to
+	describe each commit.  '<format>' can be any string accepted
+	by the `--format` option of 'git log', such as '* [%h] %s'.
+	(See the "PRETTY FORMATS" section of linkgit:git-log[1].)
+
+	Each pretty-printed commit will be rewrapped before it is shown.
+
+--date=<format>::
+	Show dates formatted according to the given date string. (See
+	the `--date` option in the "Commit Formatting" section of
+	linkgit:git-log[1]). Useful with `--group=format:<format>`.
+
+--group=<type>::
+	Group commits based on `<type>`. If no `--group` option is
+	specified, the default is `author`. `<type>` is one of:
++
+--
+ - `author`, commits are grouped by author
+ - `committer`, commits are grouped by committer (the same as `-c`)
+ - `trailer:<field>`, the `<field>` is interpreted as a case-insensitive
+   commit message trailer (see linkgit:git-interpret-trailers[1]). For
+   example, if your project uses `Reviewed-by` trailers, you might want
+   to see who has been reviewing with
+   `git shortlog -ns --group=trailer:reviewed-by`.
+ - `format:<format>`, any string accepted by the `--format` option of
+   'git log'. (See the "PRETTY FORMATS" section of
+   linkgit:git-log[1].)
++
+Note that commits that do not include the trailer will not be counted.
+Likewise, commits with multiple trailers (e.g., multiple signoffs) may
+be counted more than once (but only once per unique trailer value in
+that commit).
++
+Shortlog will attempt to parse each trailer value as a `name <email>`
+identity. If successful, the mailmap is applied and the email is omitted
+unless the `--email` option is specified. If the value cannot be parsed
+as an identity, it will be taken literally and completely.
+--
++
+If `--group` is specified multiple times, commits are counted under each
+value (but again, only once per unique value in that commit). For
+example, `git shortlog --group=author --group=trailer:co-authored-by`
+counts both authors and co-authors.
+
+-c::
+--committer::
+	This is an alias for `--group=committer`.
+
+-w[<width>[,<indent1>[,<indent2>]]]::
+	Linewrap the output by wrapping each line at `width`.  The first
+	line of each entry is indented by `indent1` spaces, and the second
+	and subsequent lines are indented by `indent2` spaces. `width`,
+	`indent1`, and `indent2` default to 76, 6 and 9 respectively.
++
+If width is `0` (zero) then indent the lines of the output without wrapping
+them.
+
+<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>...::
+	Consider only commits that are enough to explain how the files
+	that match the specified paths came to be.
++
+Paths may need to be prefixed with `--` to separate them from
+options or the revision range, when confusion arises.

+MAPPING AUTHORS
+---------------
+
+See linkgit:gitmailmap[5].
+
+Note that if `git shortlog` is run outside of a repository (to process
+log contents on standard input), it will look for a `.mailmap` file in
+the current directory.
