3 GRUF installs just like any other Zope product. Just untar it in your Products directory,
4 restart Zope, and you're done.
8 To enjoy groups within Zope, you just have to instansiate a GroupUserFolder instead of your
9 UserFolder. GRUF creates two default acl_users for you inside itself (one for Users and one
10 for Groups. see README.txt for technical explanation) but you can remove them and replace
11 them by other kind of User Folders: LDAPUserFolder, SQLUserFolder, SimpleUserFolder,
12 or whatever suits your needs.
16 See README-Plone file for explanation on Plone installation.
