submodule.<name>.url::
Defines an url from where the submodule repository can be cloned.
+ This may be either an absolute URL ready to be passed to
+ linkgit:git-clone[1] or (if it begins with ./ or ../) a location
+ relative to the superproject's origin repository.
+
+submodule.<name>.update::
+ Defines what to do when the submodule is updated by the superproject.
+ If 'checkout' (the default), the new commit specified in the
+ superproject will be checked out in the submodule on a detached HEAD.
+ If 'rebase', the current branch of the submodule will be rebased onto
+ the commit specified in the superproject. If 'merge', the commit
+ specified in the superproject will be merged into the current branch
+ in the submodule.
+ This config option is overridden if 'git submodule update' is given
+ the '--merge' or '--rebase' options.
