Subject: Git Submodule auto-update
Message-ID: <loom.20160216T022310-849@post.gmane.org>

I apologize if this is a dumb or repeated question.

Is there a way to have a submodule automatically 'update' on pull of the 
parent repository, WITHOUT requiring each user/committer to change any 
settings (hooks or git config aliases)?

Ideally, a setting I can change at the repository level and then commit 
and apply to all users who clone the repository.

Thanks.
