+DESCRIPTION
+-----------
+Create a new commit containing the current contents of the index and
+the given log message describing the changes. The new commit is a
+direct child of HEAD, usually the tip of the current branch, and the
+branch is updated to point to it (unless no branch is associated with
+the working tree, in which case HEAD is "detached" as described in
+linkgit:git-checkout[1]).
+
+The content to be committed can be specified in several ways:
+
+1. by using linkgit:git-add[1] to incrementally "add" changes to the
+   index before using the 'commit' command (Note: even modified files
+   must be "added");
+
+2. by using linkgit:git-rm[1] 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
+   (without --interactive or --patch switch), in which
+   case the commit will ignore changes staged in the index, and instead
+   record the current content of the listed files (which must already
+   be known to Git);
+
+4. by using the -a switch with the 'commit' command to automatically
+   "add" changes from all known files (i.e. all files that are already
+   listed in the index) and to automatically "rm" files in the index
+   that have been removed from the working tree, and then perform the
+   actual commit;
+
+5. by using the --interactive or --patch switches with the 'commit' command
+   to decide one by one which files or hunks should be part of the commit
+   in addition to contents in the index,
+   before finalizing the operation. See the ``Interactive Mode'' section of
+   linkgit:git-add[1] to learn how to operate these modes.
+
+The `--dry-run` option can be used to obtain a
+summary of what is included by any of the above for the next
+commit by giving the same set of parameters (options and paths).
+
+If you make a commit and then find a mistake immediately after
+that, you can recover from it with 'git reset'.
+
+
+OPTIONS
+-------
+-a::
+--all::
+	Tell the command to automatically stage files that have
+	been modified and deleted, but new files you have not
+	told Git about are not affected.
+
+-p::
+--patch::
+	Use the interactive patch selection interface to chose
+	which changes to commit. See linkgit:git-add[1] for
+	details.
+
+-C <commit>::
+--reuse-message=<commit>::
+	Take an existing commit object, and reuse the log message
+	and the authorship information (including the timestamp)
+	when creating the commit.
+
+-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
+	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 the long-format.
+	Implies `--dry-run`.
+
+-z::
+--null::
+	When showing `short` or `porcelain` status output, print the
+	filename verbatim and terminate the entries with NUL, instead of LF.
+	If no format is given, implies the `--porcelain` output format.
+	Without the `-z` option, filenames with "unusual" characters are
+	quoted as explained for the configuration variable `core.quotePath`
+	(see linkgit:git-config[1]).
+
+-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 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.
+	If multiple `-m` options are given, their values are
+	concatenated as separate paragraphs.
++
+The `-m` option is mutually exclusive with `-c`, `-C`, and `-F`.
+
+-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.  The meaning of a signoff depends on the project,
+	but it typically certifies that committer has
+	the rights to submit this work under the same license and
+	agrees to a Developer Certificate of Origin
+	(see http://developercertificate.org/ for more information).
+
+-n::
+--no-verify::
+	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 found below is truncated, if the message is to be edited.
+	"`#`" can be customized with core.commentChar.
+
+		# ------------------------ >8 ------------------------
+
+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::
+	The message taken from file with `-F`, command line with
+	`-m`, and from commit object with `-C` are usually used as
+	the commit log message unmodified. This option lets you
+	further edit the message taken from these sources.
+
+--no-edit::
+	Use the selected commit message without launching an editor.
+	For example, `git commit --amend --no-edit` amends a commit
+	without changing its commit message.
+
+--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
+	other message is specified from the command line via options
+	such as `-m`, `-F`, `-c`, etc.  The new commit has the same
+	parents and author as the current one (the `--reset-author`
+	option can countermand this).
++
+--
+It is a rough equivalent for:
+------
+	$ git reset --soft HEAD^
+	$ ... do something else to come up with the right tree ...
+	$ git commit -c ORIG_HEAD
+
+------
+but can be used to amend a merge commit.
+--
++
+You should understand the implications of rewriting history if you
+amend a commit that has already been published.  (See the "RECOVERING
+FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
+
+--no-post-rewrite::
+	Bypass the post-rewrite hook.
+
+-i::
+--include::
+	Before making a commit out of staged contents so far,
+	stage the contents of paths given on the command line
+	as well.  This is usually not what you want unless you
+	are concluding a conflicted merge.
+
+-o::
+--only::
+	Make a commit by taking the updated working tree contents
+	of the paths specified on the
+	command line, disregarding any contents that have been
+	staged for other paths. This is the default mode of operation of
+	'git commit' if any paths are given on the command line,
+	in which case this option can be omitted.
+	If this option is specified together with `--amend`, then
+	no paths need to be specified, which can be used to amend
+	the last commit without committing changes that have
+	already been staged. If used together with `--allow-empty`
+	paths are also not required, and an empty commit will be created.
+
+-u[<mode>]::
+--untracked-files[=<mode>]::
+	Show untracked files.
++
+The mode parameter is optional (defaults to 'all'), and is used to
+specify the handling of untracked files; when -u is not used, the
+default is 'normal', i.e. show untracked files and directories.
++
+The possible options are:
++
+	- 'no'     - Show no untracked files
+	- 'normal' - Shows untracked files and directories
+	- 'all'    - Also shows individual files in untracked directories.
++
+The default can be changed using the status.showUntrackedFiles
+configuration variable documented in linkgit:git-config[1].
+
+-v::
+--verbose::
+	Show unified diff between the HEAD commit and what
+	would be committed at the bottom of the commit message
+	template to help the user describe the commit by reminding
+	what changes the commit has.
+	Note that this diff output doesn't have its
+	lines prefixed with '#'. This diff will not be a part
+	of the commit message. See the `commit.verbose` configuration
+	variable in linkgit:git-config[1].
++
+If specified twice, show in addition the unified diff between
+what would be committed and the worktree files, i.e. the unstaged
+changes to tracked files.
+
+-q::
+--quiet::
+	Suppress commit summary message.
+
+--dry-run::
+	Do not create a commit, but show a list of paths that are
+	to be committed, paths with local changes that will be left
+	uncommitted and paths that are untracked.
+
+--status::
+	Include the output of linkgit:git-status[1] in the commit
+	message template when using an editor to prepare the commit
+	message.  Defaults to on, but can be used to override
+	configuration variable commit.status.
+
+--no-status::
+	Do not include the output of linkgit:git-status[1] in the
+	commit message template when using an editor to prepare the
+	default 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
+	stuck to the option without a space.
+
+--no-gpg-sign::
+	Countermand `commit.gpgSign` configuration variable that is
+	set to force each and every commit to be signed.
+
+\--::
+	Do not interpret any more arguments as options.
+
+<file>...::
+	When files are given on the command line, the command
+	commits the contents of the named files, without
+	recording the changes already staged.  The contents of
+	these files are also staged for the next commit on top
+	of what have been staged before.

+
+EXAMPLES
+--------
+When recording your own work, the contents of modified files in
+your working tree are temporarily stored to a staging area
+called the "index" with 'git add'.  A file can be
+reverted back, only in the index but not in the working tree,
+to that of the last commit with `git restore --staged <file>`,
+which effectively reverts 'git add' and prevents the changes to
+this file from participating in the next commit.  After building
+the state to be committed incrementally with these commands,
+`git commit` (without any pathname parameter) is used to record what
+has been staged so far.  This is the most basic form of the
+command.  An example:
+
+------------
+$ edit hello.c
+$ git rm goodbye.c
+$ git add hello.c
+$ git commit
+------------
+
+Instead of staging files after each individual change, you can
+tell `git commit` to notice the changes to the files whose
+contents are tracked in
+your working tree and do corresponding `git add` and `git rm`
+for you.  That is, this example does the same as the earlier
+example if there is no other change in your working tree:
+
+------------
+$ edit hello.c
+$ rm goodbye.c
+$ git commit -a
+------------
+
+The command `git commit -a` first looks at your working tree,
+notices that you have modified hello.c and removed goodbye.c,
+and performs necessary `git add` and `git rm` for you.
+
+After staging changes to many files, you can alter the order the
+changes are recorded in, by giving pathnames to `git commit`.
+When pathnames are given, the command makes a commit that
+only records the changes made to the named paths:
+
+------------
+$ edit hello.c hello.h
+$ git add hello.c hello.h
+$ edit Makefile
+$ git commit Makefile
+------------
+
+This makes a commit that records the modification to `Makefile`.
+The changes staged for `hello.c` and `hello.h` are not included
+in the resulting commit.  However, their changes are not lost --
+they are still staged and merely held back.  After the above
+sequence, if you do:
+
+------------
+$ git commit
+------------
+
+this second commit would record the changes to `hello.c` and
+`hello.h` as expected.
+
+After a merge (initiated by 'git merge' or 'git pull') stops
+because of conflicts, cleanly merged
+paths are already staged to be committed for you, and paths that
+conflicted are left in unmerged state.  You would have to first
+check which paths are conflicting with 'git status'
+and after fixing them manually in your working tree, you would
+stage the result as usual with 'git add':
+
+------------
+$ git status | grep unmerged
+unmerged: hello.c
+$ edit hello.c
+$ git add hello.c
+------------
+
+After resolving conflicts and staging the result, `git ls-files -u`
+would stop mentioning the conflicted path.  When you are done,
+run `git commit` to finally record the merge:
+
+------------
+$ git commit
+------------
+
+As with the case to record your own changes, you can use `-a`
+option to save typing.  One difference is that during a merge
+resolution, you cannot use `git commit` with pathnames to
+alter the order the changes are committed, because the merge
+should be recorded as a single commit.  In fact, the command
+refuses to run when given pathnames (but see `-i` option).
+
+
+DISCUSSION
+----------
+
+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.

+
+ENVIRONMENT AND CONFIGURATION VARIABLES
+---------------------------------------
+The editor used to edit the commit log message will be chosen from the
+`GIT_EDITOR` environment variable, the core.editor configuration variable, the
+`VISUAL` environment variable, or the `EDITOR` environment variable (in that
+order).  See linkgit:git-var[1] for details.
+
+HOOKS
+-----
+This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
+`post-commit` and `post-rewrite` hooks.  See linkgit:githooks[5] for more
+information.
+
+FILES
+-----
+
+`$GIT_DIR/COMMIT_EDITMSG`::
+	This file contains the commit message of a commit in progress.
+	If `git commit` exits due to an error before creating a commit,
+	any commit message that has been provided by the user (e.g., in
+	an editor session) will be available in this file, but will be
+	overwritten by the next invocation of `git commit`.
