I've been working with wiki-variants for kinda a while -- kwiki came
along with a few new (at the time) features, including primitive ACLs
(usernames) and a "publish" (static HTML gen), and some aliasing / URL
mapping capabilities.

My ultimate goal is (and has been) a "home page management system";
something more friendly / more GUI than vi + .shtml, but still
lightweight and platform-independent.

k2 was after kwiki, an entirely OO shot. Some good ideas, but it
didn't really fly.

k3 is much better. Structure (directories for namespace),
attachments, ACLs, and maybe some other stuff I'd like to use on my
web content.

Not ready for distro, but the curious can look at
