Ruwiki is a simple, extensible Wiki-clone written in Ruby. It supports both CGI and WEBrick interfaces, templates, and CSS formatting. This Wiki differs from most other Wikis in that it supports project namespaces, so that two topics may be named the same for differing projects without colliding or having to resort to odd naming conventions. Please see the ::Ruwiki project in the running Wiki for more information. Ruwiki %RV#% has German and Spanish translations available.
