[Zope] UserDB Folder.

Hello all, I've dug up the UserDB folder in the old Zope.org site. However, before I try it, I'd like to find out if it's compatable with Zope 2. I can't find any information one way or the other, but I can only assume it's not, since it doesn't exist on the new Zope.org site, yet. Anyone know for sure? -Otto.
