submodule.<name>.url::
	The URL for a submodule. This variable is copied from the .gitmodules
	file to the git config via 'git submodule init'. The user can change
	the configured URL before obtaining the submodule via 'git submodule
	update'. If neither submodule.<name>.active or submodule.active are
	set, the presence of this variable is used as a fallback to indicate
	whether the submodule is of interest to git commands.
	See linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.

submodule.<name>.update::
	The method by which a submodule is updated by 'git submodule update',
	which is the only affected command, others such as
	'git checkout --recurse-submodules' are unaffected. It exists for
	historical reasons, when 'git submodule' was the only command to
	interact with submodules; settings like `submodule.active`
	and `pull.rebase` are more specific. It is populated by
	`git submodule init` from the linkgit:gitmodules[5] file.
	See description of 'update' command in linkgit:git-submodule[1].

submodule.<name>.branch::
	The remote branch name for a submodule, used by `git submodule
	update --remote`.  Set this option to override the value found in
	the `.gitmodules` file.  See linkgit:git-submodule[1] and
	linkgit:gitmodules[5] for details.

submodule.<name>.fetchRecurseSubmodules::
	This option can be used to control recursive fetching of this
	submodule. It can be overridden by using the --[no-]recurse-submodules
	command-line option to "git fetch" and "git pull".
	This setting will override that from in the linkgit:gitmodules[5]
	file.

submodule.<name>.ignore::
	Defines under what circumstances "git status" and the diff family show
	a submodule as modified. When set to "all", it will never be considered
	modified (but it will nonetheless show up in the output of status and
	commit when it has been staged), "dirty" will ignore all changes
	to the submodules work tree and
	takes only differences between the HEAD of the submodule and the commit
	recorded in the superproject into account. "untracked" will additionally
	let submodules with modified tracked files in their work tree show up.
	Using "none" (the default when this option is not set) also shows
	submodules that have untracked files in their work tree as changed.
	This setting overrides any setting made in .gitmodules for this submodule,
	both settings can be overridden on the command line by using the
	"--ignore-submodules" option. The 'git submodule' commands are not
	affected by this setting.

submodule.<name>.active::
	Boolean value indicating if the submodule is of interest to git
	commands.  This config option takes precedence over the
	submodule.active config option. See linkgit:gitsubmodules[7] for
	details.

submodule.active::
	A repeated field which contains a pathspec used to match against a
	submodule's path to determine if the submodule is of interest to git
	commands. See linkgit:gitsubmodules[7] for details.

submodule.recurse::
	Specifies if commands recurse into submodules by default. This
	applies to all commands that have a `--recurse-submodules` option
	(`checkout`, `fetch`, `grep`, `pull`, `push`, `read-tree`, `reset`,
	`restore` and `switch`) except `clone` and `ls-files`.
	Defaults to false.
	When set to true, it can be deactivated via the
	`--no-recurse-submodules` option. Note that some Git commands
	lacking this option may call some of the above commands affected by
	`submodule.recurse`; for instance `git remote update` will call
	`git fetch` but does not have a `--no-recurse-submodules` option.
	For these commands a workaround is to temporarily change the
	configuration value by using `git -c submodule.recurse=0`.

submodule.fetchJobs::
	Specifies how many submodules are fetched/cloned at the same time.
	A positive integer allows up to that number of submodules fetched
	in parallel. A value of 0 will give some reasonable default.
	If unset, it defaults to 1.

submodule.alternateLocation::
	Specifies how the submodules obtain alternates when submodules are
	cloned. Possible values are `no`, `superproject`.
	By default `no` is assumed, which doesn't add references. When the
	value is set to `superproject` the submodule to be cloned computes
	its alternates location relative to the superprojects alternate.

submodule.alternateErrorStrategy::
	Specifies how to treat errors with the alternates for a submodule
	as computed via `submodule.alternateLocation`. Possible values are
	`ignore`, `info`, `die`. Default is `die`. Note that if set to `ignore`
	or `info`, and if there is an error with the computed alternate, the
	clone proceeds as if no alternate was specified.
