OPTIONS
-------
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.
+
--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 linkgit:git-clone[1] command.
+
*NOTE*: Do *not* use this option unless you have read the note
-for linkgit:git-clone[1]'s --reference and --shared options carefully.
+for linkgit:git-clone[1]'s `--reference` and `--shared` options carefully.
--recursive::
This option is only valid for foreach, update and status commands.
