  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 a URL from which 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        If 'none', the submodule with name `$name` will not be updated
  45        by default.
  46
  47        This config option is overridden if 'git submodule update' is given
  48        the '--merge', '--rebase' or '--checkout' options.
  49
  50submodule.<name>.fetchRecurseSubmodules::
  51        This option can be used to control recursive fetching of this
  52        submodule. If this option is also present in the submodules entry in
  53        .git/config of the superproject, the setting there will override the
  54        one found in .gitmodules.
  55        Both settings can be overridden on the command line by using the
  56        "--[no-]recurse-submodules" option to "git fetch" and "git pull".
  57
  58submodule.<name>.ignore::
  59        Defines under what circumstances "git status" and the diff family show
  60        a submodule as modified. When set to "all", it will never be considered
  61        modified, "dirty" will ignore all changes to the submodules work tree and
  62        takes only differences between the HEAD of the submodule and the commit
  63        recorded in the superproject into account. "untracked" will additionally
  64        let submodules with modified tracked files in their work tree show up.
  65        Using "none" (the default when this option is not set) also shows
  66        submodules that have untracked files in their work tree as changed.
  67        If this option is also present in the submodules entry in .git/config of
  68        the superproject, the setting there will override the one found in
  69        .gitmodules.
  70        Both settings can be overridden on the command line by using the
  71        "--ignore-submodule" option.

  74EXAMPLES
  75--------
  76
  77Consider the following .gitmodules file:
  78
  79        [submodule "libfoo"]
  80                path = include/foo
  81                url = git://foo.com/git/lib.git
  82
  83        [submodule "libbar"]
  84                path = include/bar
  85                url = git://bar.com/git/lib.git
  86
  87
  88This defines two submodules, `libfoo` and `libbar`. These are expected to
  89be checked out in the paths 'include/foo' and 'include/bar', and for both
  90submodules a URL is specified which can be used for cloning the submodules.
