"""
BitBake 'Fetch' git submodules implementation
Inherits from and extends the Git fetcher to retrieve submodules of a git repository
after cloning.
SRC_URI = "gitsm://<see Git fetcher for syntax>"
See the Git fetcher, git://, for usage documentation.
NOTE: Switching a SRC_URI from "git://" to "gitsm://" requires a clean of your recipe.
