A wiki as a plugin?

hello everybody

I would like to integrate a small wiki in my current rails-project. but
before writing it on my own, I’d like to know, if there is already a
plugin for rails.

i know about instiki and http://agilewebdevelopment.com/plugins/macaque
but where the first is designed as a single application, the second hast
not the functionality i prefer.

do you know about other plugins, rails-wikis, which are easy to

I also don’t want to use a “standard” wiki like mediawiki, moinmoin
etc., because they make use from other scripting-languages.
