DESCRIPTION
       Inspects, updates and manages submodules.

       For more information about submodules, see gitsubmodules(7).

COMMANDS
       With no arguments, shows the status of existing submodules. Several
       subcommands are available to perform operations on the submodules.

       add [-b <branch>] [-f|--force] [--name <name>] [--reference
       <repository>] [--depth <depth>] [--] <repository> [<path>]
	   Add the given repository as a submodule at the given path to the
	   changeset to be committed next to the current project: the current
	   project is termed the "superproject".

	   <repository> is the URL of the new submodule's origin repository.
	   This may be either an absolute URL, or (if it begins with ./ or
	   ../), the location relative to the superproject's default remote
	   repository (Please note that to specify a repository foo.git which
	   is located right next to a superproject bar.git, you'll have to use
	   ../foo.git instead of ./foo.git - as one might expect when
	   following the rules for relative URLs - because the evaluation of
	   relative URLs in Git is identical to that of relative directories).

	   The default remote is the remote of the remote-tracking branch of
	   the current branch. If no such remote-tracking branch exists or the
	   HEAD is detached, "origin" is assumed to be the default remote. If
	   the superproject doesn't have a default remote configured the
	   superproject is its own authoritative upstream and the current
	   working directory is used instead.

	   The optional argument <path> is the relative location for the
	   cloned submodule to exist in the superproject. If <path> is not
	   given, the canonical part of the source repository is used ("repo"
	   for "/path/to/repo.git" and "foo" for "host.xz:foo/.git"). If
	   <path> exists and is already a valid Git repository, then it is
	   staged for commit without cloning. The <path> is also used as the
	   submodule's logical name in its configuration entries unless --name
	   is used to specify a logical name.

	   The given URL is recorded into .gitmodules for use by subsequent
	   users cloning the superproject. If the URL is given relative to the
	   superproject's repository, the presumption is the superproject and
	   submodule repositories will be kept together in the same relative
	   location, and only the superproject's URL needs to be provided.
	   git-submodule will correctly locate the submodule using the
	   relative URL in .gitmodules.

       status [--cached] [--recursive] [--] [<path>...]
	   Show the status of the submodules. This will print the SHA-1 of the
	   currently checked out commit for each submodule, along with the
	   submodule path and the output of git describe for the SHA-1. Each
	   SHA-1 will possibly be prefixed with - if the submodule is not
	   initialized, + if the currently checked out submodule commit does
	   not match the SHA-1 found in the index of the containing repository
	   and U if the submodule has merge conflicts.

	   If --cached is specified, this command will instead print the SHA-1
	   recorded in the superproject for each submodule.

	   If --recursive is specified, this command will recurse into nested
	   submodules, and show their status as well.

	   If you are only interested in changes of the currently initialized
	   submodules with respect to the commit recorded in the index or the
	   HEAD, git-status(1) and git-diff(1) will provide that information
	   too (and can also report changes to a submodule's work tree).

       init [--] [<path>...]
	   Initialize the submodules recorded in the index (which were added
	   and committed elsewhere) by setting submodule.$name.url in
	   .git/config. It uses the same setting from .gitmodules as a
	   template. If the URL is relative, it will be resolved using the
	   default remote. If there is no default remote, the current
	   repository will be assumed to be upstream.

	   Optional <path> arguments limit which submodules will be
	   initialized. If no path is specified and submodule.active has been
	   configured, submodules configured to be active will be initialized,
	   otherwise all submodules are initialized.

	   When present, it will also copy the value of
	   submodule.$name.update. This command does not alter existing
	   information in .git/config. You can then customize the submodule
	   clone URLs in .git/config for your local setup and proceed to git
	   submodule update; you can also just use git submodule update --init
	   without the explicit init step if you do not intend to customize
	   any submodule locations.

	   See the add subcommand for the definition of default remote.

       deinit [-f|--force] (--all|[--] <path>...)
	   Unregister the given submodules, i.e. remove the whole
	   submodule.$name section from .git/config together with their work
	   tree. Further calls to git submodule update, git submodule foreach
	   and git submodule sync will skip any unregistered submodules until
	   they are initialized again, so use this command if you don't want
	   to have a local checkout of the submodule in your working tree
	   anymore.

	   When the command is run without pathspec, it errors out, instead of
	   deinit-ing everything, to prevent mistakes.

	   If --force is specified, the submodule's working tree will be
	   removed even if it contains local modifications.

	   If you really want to remove a submodule from the repository and
	   commit that use git-rm(1) instead. See gitsubmodules(7) for removal
	   options.

       update [--init] [--remote] [-N|--no-fetch] [--[no-]recommend-shallow]
       [-f|--force] [--checkout|--rebase|--merge] [--reference <repository>]
       [--depth <depth>] [--recursive] [--jobs <n>] [--[no-]single-branch]
       [--filter <filter spec>] [--] [<path>...]
	   Update the registered submodules to match what the superproject
	   expects by cloning missing submodules, fetching missing commits in
	   submodules and updating the working tree of the submodules. The
	   "updating" can be done in several ways depending on command line
	   options and the value of submodule.<name>.update configuration
	   variable. The command line option takes precedence over the
	   configuration variable. If neither is given, a checkout is
	   performed. The update procedures supported both from the command
	   line as well as through the submodule.<name>.update configuration
	   are:

	   checkout
	       the commit recorded in the superproject will be checked out in
	       the submodule on a detached HEAD.

	       If --force is specified, the submodule will be checked out
	       (using git checkout --force), even if the commit specified in
	       the index of the containing repository already matches the
	       commit checked out in the submodule.

	   rebase
	       the current branch of the submodule will be rebased onto the
	       commit recorded in the superproject.

	   merge
	       the commit recorded in the superproject will be merged into the
	       current branch in the submodule.

	   The following update procedures are only available via the
	   submodule.<name>.update configuration variable:

	   custom command
	       arbitrary shell command that takes a single argument (the sha1
	       of the commit recorded in the superproject) is executed. When
	       submodule.<name>.update is set to !command, the remainder after
	       the exclamation mark is the custom command.

	   none
	       the submodule is not updated.

	   If the submodule is not yet initialized, and you just want to use
	   the setting as stored in .gitmodules, you can automatically
	   initialize the submodule with the --init option.

	   If --recursive is specified, this command will recurse into the
	   registered submodules, and update any nested submodules within.

	   If --filter <filter spec> is specified, the given partial clone
	   filter will be applied to the submodule. See git-rev-list(1) for
	   details on filter specifications.

       set-branch (-b|--branch) <branch> [--] <path>, set-branch
       (-d|--default) [--] <path>
	   Sets the default remote tracking branch for the submodule. The
	   --branch option allows the remote branch to be specified. The
	   --default option removes the submodule.<name>.branch configuration
	   key, which causes the tracking branch to default to the remote
	   HEAD.

       set-url [--] <path> <newurl>
	   Sets the URL of the specified submodule to <newurl>. Then, it will
	   automatically synchronize the submodule's new remote URL
	   configuration.

       summary [--cached|--files] [(-n|--summary-limit) <n>] [commit] [--]
       [<path>...]
	   Show commit summary between the given commit (defaults to HEAD) and
	   working tree/index. For a submodule in question, a series of
	   commits in the submodule between the given super project commit and
	   the index or working tree (switched by --cached) are shown. If the
	   option --files is given, show the series of commits in the
	   submodule between the index of the super project and the working
	   tree of the submodule (this option doesn't allow to use the
	   --cached option or to provide an explicit commit).

	   Using the --submodule=log option with git-diff(1) will provide that
	   information too.

       foreach [--recursive] <command>
	   Evaluates an arbitrary shell command in each checked out submodule.
	   The command has access to the variables $name, $sm_path,
	   $displaypath, $sha1 and $toplevel: $name is the name of the
	   relevant submodule section in .gitmodules, $sm_path is the path of
	   the submodule as recorded in the immediate superproject,
	   $displaypath contains the relative path from the current working
	   directory to the submodules root directory, $sha1 is the commit as
	   recorded in the immediate superproject, and $toplevel is the
	   absolute path to the top-level of the immediate superproject. Note
	   that to avoid conflicts with $PATH on Windows, the $path variable
	   is now a deprecated synonym of $sm_path variable. Any submodules
	   defined in the superproject but not checked out are ignored by this
	   command. Unless given --quiet, foreach prints the name of each
	   submodule before evaluating the command. If --recursive is given,
	   submodules are traversed recursively (i.e. the given shell command
	   is evaluated in nested submodules as well). A non-zero return from
	   the command in any submodule causes the processing to terminate.
	   This can be overridden by adding || : to the end of the command.

	   As an example, the command below will show the path and currently
	   checked out commit for each submodule:

	       git submodule foreach 'echo $sm_path `git rev-parse HEAD`'


       sync [--recursive] [--] [<path>...]
	   Synchronizes submodules' remote URL configuration setting to the
	   value specified in .gitmodules. It will only affect those
	   submodules which already have a URL entry in .git/config (that is
	   the case when they are initialized or freshly added). This is
	   useful when submodule URLs change upstream and you need to update
	   your local repositories accordingly.

	   git submodule sync synchronizes all submodules while git submodule
	   sync -- A synchronizes submodule "A" only.

	   If --recursive is specified, this command will recurse into the
	   registered submodules, and sync any nested submodules within.

       absorbgitdirs
	   If a git directory of a submodule is inside the submodule, move the
	   git directory of the submodule into its superproject's
	   $GIT_DIR/modules path and then connect the git directory and its
	   working directory by setting the core.worktree and adding a .git
	   file pointing to the git directory embedded in the superprojects
	   git directory.

	   A repository that was cloned independently and later added as a
	   submodule or old setups have the submodules git directory inside
	   the submodule instead of embedded into the superprojects git
	   directory.

	   This command is recursive by default.

OPTIONS
       -q, --quiet
	   Only print error messages.

       --progress
	   This option is only valid for add and update commands. Progress
	   status is reported on the standard error stream by default when it
	   is attached to a terminal, unless -q is specified. This flag forces
	   progress status even if the standard error stream is not directed
	   to a terminal.

       --all
	   This option is only valid for the deinit command. Unregister all
	   submodules in the working tree.

       -b <branch>, --branch <branch>
	   Branch of repository to add as submodule. The name of the branch is
	   recorded as submodule.<name>.branch in .gitmodules for update
	   --remote. A special value of .  is used to indicate that the name
	   of the branch in the submodule should be the same name as the
	   current branch in the current repository. If the option is not
	   specified, it defaults to the remote HEAD.

       -f, --force
	   This option is only valid for add, deinit and update commands. When
	   running add, allow adding an otherwise ignored submodule path. When
	   running deinit the submodule working trees will be removed even if
	   they contain local changes. When running update (only effective
	   with the checkout procedure), throw away local changes in
	   submodules when switching to a different commit; and always run a
	   checkout operation in the submodule, even if the commit listed in
	   the index of the containing repository matches the commit checked
	   out in the submodule.

       --cached
	   This option is only valid for status and summary commands. These
	   commands typically use the commit found in the submodule HEAD, but
	   with this option, the commit stored in the index is used instead.

       --files
	   This option is only valid for the summary command. This command
	   compares the commit in the index with that in the submodule HEAD
	   when this option is used.

       -n, --summary-limit
	   This option is only valid for the summary command. Limit the
	   summary size (number of commits shown in total). Giving 0 will
	   disable the summary; a negative number means unlimited (the
	   default). This limit only applies to modified submodules. The size
	   is always limited to 1 for added/deleted/typechanged submodules.

       --remote
	   This option is only valid for the update command. Instead of using
	   the superproject's recorded SHA-1 to update the submodule, use the
	   status of the submodule's remote-tracking branch. The remote used
	   is branch's remote (branch.<name>.remote), defaulting to origin.
	   The remote branch used defaults to the remote HEAD, but the branch
	   name may be overridden by setting the submodule.<name>.branch
	   option in either .gitmodules or .git/config (with .git/config
	   taking precedence).

	   This works for any of the supported update procedures (--checkout,
	   --rebase, etc.). The only change is the source of the target SHA-1.
	   For example, submodule update --remote --merge will merge upstream
	   submodule changes into the submodules, while submodule update
	   --merge will merge superproject gitlink changes into the
	   submodules.

	   In order to ensure a current tracking branch state, update --remote
	   fetches the submodule's remote repository before calculating the
	   SHA-1. If you don't want to fetch, you should use submodule update
	   --remote --no-fetch.

	   Use this option to integrate changes from the upstream subproject
	   with your submodule's current HEAD. Alternatively, you can run git
	   pull from the submodule, which is equivalent except for the remote
	   branch name: update --remote uses the default upstream repository
	   and submodule.<name>.branch, while git pull uses the submodule's
	   branch.<name>.merge. Prefer submodule.<name>.branch if you want to
	   distribute the default upstream branch with the superproject and
	   branch.<name>.merge if you want a more native feel while working in
	   the submodule itself.

       -N, --no-fetch
	   This option is only valid for the update command. Don't fetch new
	   objects from the remote site.

       --checkout
	   This option is only valid for the update command. Checkout the
	   commit recorded in the superproject on a detached HEAD in the
	   submodule. This is the default behavior, the main use of this
	   option is to override submodule.$name.update when set to a value
	   other than checkout. If the key submodule.$name.update is either
	   not explicitly set or set to checkout, this option is implicit.

       --merge
	   This option is only valid for the update command. Merge the commit
	   recorded in the superproject into the current branch of the
	   submodule. If this option is given, the submodule's HEAD will not
	   be detached. If a merge failure prevents this process, you will
	   have to resolve the resulting conflicts within the submodule with
	   the usual conflict resolution tools. If the key
	   submodule.$name.update is set to merge, this option is implicit.

       --rebase
	   This option is only valid for the update command. Rebase the
	   current branch onto the commit recorded in the superproject. If
	   this option is given, the submodule's HEAD will not be detached. If
	   a merge failure prevents this process, you will have to resolve
	   these failures with git-rebase(1). If the key
	   submodule.$name.update is set to rebase, this option is implicit.

       --init
	   This option is only valid for the update command. Initialize all
	   submodules for which "git submodule init" has not been called so
	   far before updating.

       --name
	   This option is only valid for the add command. It sets the
	   submodule's name to the given string instead of defaulting to its
	   path. The name must be valid as a directory name and may not end
	   with a /.

       --reference <repository>
	   This option is only valid for add and update commands. These
	   commands sometimes need to clone a remote repository. In this case,
	   this option will be passed to the git-clone(1) command.

	   NOTE: Do not use this option unless you have read the note for git-
	   clone(1)'s --reference, --shared, and --dissociate options
	   carefully.

       --dissociate
	   This option is only valid for add and update commands. These
	   commands sometimes need to clone a remote repository. In this case,
	   this option will be passed to the git-clone(1) command.

	   NOTE: see the NOTE for the --reference option.

       --recursive
	   This option is only valid for foreach, update, status and sync
	   commands. Traverse submodules recursively. The operation is
	   performed not only in the submodules of the current repo, but also
	   in any nested submodules inside those submodules (and so on).

       --depth
	   This option is valid for add and update commands. Create a shallow
	   clone with a history truncated to the specified number of
	   revisions. See git-clone(1)

       --[no-]recommend-shallow
	   This option is only valid for the update command. The initial clone
	   of a submodule will use the recommended submodule.<name>.shallow as
	   provided by the .gitmodules file by default. To ignore the
	   suggestions use --no-recommend-shallow.

       -j <n>, --jobs <n>
	   This option is only valid for the update command. Clone new
	   submodules in parallel with as many jobs. Defaults to the
	   submodule.fetchJobs option.

       --[no-]single-branch
	   This option is only valid for the update command. Clone only one
	   branch during update: HEAD or one specified by --branch.

       <path>...
	   Paths to submodule(s). When specified this will restrict the
	   command to only operate on the submodules found at the specified
	   paths. (This argument is required with add).

FILES
       When initializing submodules, a .gitmodules file in the top-level
       directory of the containing repository is used to find the url of each
       submodule. This file should be formatted in the same way as
       $GIT_DIR/config. The key to each submodule url is
       "submodule.$name.url". See gitmodules(5) for details.
