+# NOTE(dhellmann): Ming is necessary to provide the Mongo-in-memory

+# be a way to point to a "zipball" of the latest HEAD there, and we
+# need features present only in that version. I forked the project to
+# github to make it easier to install, then ended up making some
+# changes to it so it would be compatible with PyMongo's API.
