+# - pinned down to tag objects (e.g. "9.0.1")
+# - tracking upstream remote HEAD on a stable or master branch
+# FIXME(alav): Should we support mixed cases? (e.g. pin down only fuel-main)
+
+# To enable remote tracking, set the following var to any non-empty string.
+# Leaving this var empty will bind each git submodule to its saved commit.
+# NOTE: For non-stable branches, unless overriden, always track remotes
