  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. Each submodule section also contains the
  22following required keys:
  23
  24submodule.<name>.path::
  25        Defines the path, relative to the top-level directory of the git
  26        working tree, where the submodule is expected to be checked out.
  27        The path name must not end with a `/`. All submodule paths must
  28        be unique within the .gitmodules file.
  29
  30submodule.<name>.url::
  31        Defines an url from where the submodule repository can be cloned.
  32        This may be either an absolute URL ready to be passed to
  33        linkgit:git-clone[1] or (if it begins with ./ or ../) a location
  34        relative to the superproject's origin repository.
  35
  36submodule.<name>.update::
  37        Defines what to do when the submodule is updated by the superproject.
  38        If 'checkout' (the default), the new commit specified in the
  39        superproject will be checked out in the submodule on a detached HEAD.
  40        If 'rebase', the current branch of the submodule will be rebased onto
  41        the commit specified in the superproject. If 'merge', the commit
  42        specified in the superproject will be merged into the current branch
  43        in the submodule.
  44        This config option is overridden if 'git submodule update' is given
  45        the '--merge' or '--rebase' options.
  46
  47submodule.<name>.fetchRecurseSubmodules::
  48        This option can be used to control recursive fetching of this
  49        submodule. If this option is also present in the submodules entry in
  50        .git/config of the superproject, the setting there will override the
  51        one found in .gitmodules.
  52        Both settings can be overridden on the command line by using the
  53        "--[no-]recurse-submodules" option to "git fetch" and "git pull".
  54
  55submodule.<name>.ignore::
  56        Defines under what circumstances "git status" and the diff family show
  57        a submodule as modified. When set to "all", it will never be considered
  58        modified, "dirty" will ignore all changes to the submodules work tree and
  59        takes only differences between the HEAD of the submodule and the commit
  60        recorded in the superproject into account. "untracked" will additionally
  61        let submodules with modified tracked files in their work tree show up.
  62        Using "none" (the default when this option is not set) also shows
  63        submodules that have untracked files in their work tree as changed.
  64        If this option is also present in the submodules entry in .git/config of
  65        the superproject, the setting there will override the one found in
  66        .gitmodules.
  67        Both settings can be overridden on the command line by using the
  68        "--ignore-submodule" option.

  71EXAMPLES
  72--------
  73
  74Consider the following .gitmodules file:
  75
  76        [submodule "libfoo"]
  77                path = include/foo
  78                url = git://foo.com/git/lib.git
  79
  80        [submodule "libbar"]
  81                path = include/bar
  82                url = git://bar.com/git/lib.git
  83
  84
  85This defines two submodules, `libfoo` and `libbar`. These are expected to
  86be checked out in the paths 'include/foo' and 'include/bar', and for both
  87submodules an url is specified which can be used for cloning the submodules.
