+foreach::
+       Evaluates an arbitrary shell command in each checked out submodule.
+       The command has access to the variables $path and $sha1:
+       $path is the name of the submodule directory relative to the
+       superproject, and $sha1 is the commit as recorded in the superproject.
+       Any submodules defined in the superproject but not checked out are
+       ignored by this command. Unless given --quiet, foreach prints the name
+       of each submodule before evaluating the command.
+       A non-zero return from the command in any submodule causes
+       the processing to terminate. This can be overridden by adding '|| :'
+       to the end of the command.

+As an example, "git submodule foreach 'echo $path `git rev-parse HEAD`' will
+show the path and currently checked out commit for each submodule.

+sync::
+       Synchronizes submodules' remote URL configuration setting
