+# Clone the edx-platform repo for speedier future use.
+# A couple notes:
+# 1) This is done for the other workers in the test_build_server role,
+#    which is not intuitive and should probably be refactored.
+# 2) Flow jobs really should not need to clone the repo, but
+#    it would be some work to refactor. See TE-2333.
