  13DESCRIPTION
  14-----------
  15
  16The `.gitmodules` file, located in the top-level directory of a Git
  17working tree, is a text file with a syntax matching the requirements
  18of linkgit:git-config[1].
  19
  20The file contains one subsection per submodule, and the subsection value
  21is the name of the submodule. The name is set to the path where the
  22submodule has been added unless it was customized with the '--name'
  23option of 'git submodule add'. Each submodule section also contains the
  24following required keys:
  25
  26submodule.<name>.path::
  27        Defines the path, relative to the top-level directory of the Git
  28        working tree, where the submodule is expected to be checked out.
  29        The path name must not end with a `/`. All submodule paths must
  30        be unique within the .gitmodules file.
  31
  32submodule.<name>.url::
  33        Defines a URL from which the submodule repository can be cloned.
  34        This may be either an absolute URL ready to be passed to
  35        linkgit:git-clone[1] or (if it begins with ./ or ../) a location
  36        relative to the superproject's origin repository.
  37
  38In addition, there are a number of optional keys:
  39
  40submodule.<name>.update::
  41        Defines what to do when the submodule is updated by the superproject.
  42        If 'checkout' (the default), the new commit specified in the
  43        superproject will be checked out in the submodule on a detached HEAD.
  44        If 'rebase', the current branch of the submodule will be rebased onto
  45        the commit specified in the superproject. If 'merge', the commit
  46        specified in the superproject will be merged into the current branch
  47        in the submodule.
  48        If 'none', the submodule with name `$name` will not be updated
  49        by default.
  50
  51        This config option is overridden if 'git submodule update' is given
  52        the '--merge', '--rebase' or '--checkout' options.
  53
  54submodule.<name>.branch::
  55        A remote branch name for tracking updates in the upstream submodule.
  56        If the option is not specified, it defaults to 'master'.  See the
  57        `--remote` documentation in linkgit:git-submodule[1] for details.
  58
  59submodule.<name>.fetchRecurseSubmodules::
  60        This option can be used to control recursive fetching of this
  61        submodule. If this option is also present in the submodules entry in
  62        .git/config of the superproject, the setting there will override the
  63        one found in .gitmodules.
  64        Both settings can be overridden on the command line by using the
  65        "--[no-]recurse-submodules" option to "git fetch" and "git pull".
  66
  67submodule.<name>.ignore::
  68        Defines under what circumstances "git status" and the diff family show
  69        a submodule as modified. When set to "all", it will never be considered
  70        modified (but will nonetheless show up in the output of status and
  71        commit when it has been staged), "dirty" will ignore all changes
  72        to the submodules work tree and
  73        takes only differences between the HEAD of the submodule and the commit
  74        recorded in the superproject into account. "untracked" will additionally
  75        let submodules with modified tracked files in their work tree show up.
  76        Using "none" (the default when this option is not set) also shows
  77        submodules that have untracked files in their work tree as changed.
  78        If this option is also present in the submodules entry in .git/config of
  79        the superproject, the setting there will override the one found in
  80        .gitmodules.
  81        Both settings can be overridden on the command line by using the
  82        "--ignore-submodule" option. The 'git submodule' commands are not
  83        affected by this setting.

  86EXAMPLES
  87--------
  88
  89Consider the following .gitmodules file:
  90
  91        [submodule "libfoo"]
  92                path = include/foo
  93                url = git://foo.com/git/lib.git
  94
  95        [submodule "libbar"]
  96                path = include/bar
  97                url = git://bar.com/git/lib.git
  98
  99
 100This defines two submodules, `libfoo` and `libbar`. These are expected to
 101be checked out in the paths 'include/foo' and 'include/bar', and for both
 102submodules a URL is specified which can be used for cloning the submodules.
