+# with optional environment variables:

+# - GIT_REPOSITORY_CACHE=/zzz/foo.git
+#
+# the GIT_REPOSITORY_CACHE can be used with or without GIT_URL
+# - if GIT_URL is given, GIT_REPOSITORY_CACHE will be a "bare" clone of GIT_URL
+# - otherwise, GIT_REPOSITORY_CACHE can be created using:
+#   % git clone --bare BUILD/foo-1 $GIT_REPOSITORY_CACHE
+#   where foo-1 is the previous version
