CMFGUM first (and only) release!
This is a hack of morphex's ZopeGUM from the CVS version which is post-pre-alpha5, with some edits to work within CMF1.1. It works, but needs cleanup, and I dont' have the time. But I'm putting it out there because basically it was a pain to install, and there's no other options currently.
Product depenancies: You need BTreeFolder installed.
