CLiki
CLiki is an open source wiki application written in Common Lisp, that was under development from 2002 to 2005.
CLiki was first presented at the International Lisp Conference 2002. CLiki was the first wiki variant to introduce so called "free links", using the _(free link format) as an alternative to the much-criticized CamelCase.
The CLiki program is free software licensed under the MIT license. It runs under SBCL and uses the Araneida Common Lisp web server.
CLiki also operates a homepage using the software that is dedicated to the subject of Common Lisp.
