+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.
