# By default, when you clone Freedom E SDK, submodules are instantiated with their
# origin URLs pointing to GitHub's HTTPS URL for the repository.

# If you're a collaborator of this repository, it's annoying to update all the
# submodule URLs so that you can push to the repositories. This script fixes that
# by changing all the submodules to use SSH instead of HTTPS. If you're not a
# collaborator, don't bother using this script unless you really want to authenticate
# to GitHub with SSH for some reason.
