Requirements for an official NetBSD wiki:

Before selecting ikiwiki, I evaluated the following:

Software Language Versioning Comments
Sputnik Lua git or filesystem looks cool
Foswiki Perl RCS fork of TWiki, complex install docs, complex software, checkered security history
Kwiki Perl don't remember old version was so-so, the ambitious rewrite never happened
MojoMojo Perl SQL featureful
MoinMoin Python filesystem

In my opinion, ikiwiki is the best fit: written in Perl, with a simple web UI and several ways of restricting access, it not only renders arbitrary hierarchies of static pages, but also is designed to be used in concert with a variety of external revision control systems.

This one's done. --schmonz
