A SelfProgrammingWiki is a wiki in which the code of the wiki itself is collaboratively edited by its users, much like the text is in a conventional wiki. The "self" in "SelfProgrammingWiki" refers to the wiki community, rather than to some sort of A.I. in the wiki software. The page you are viewing is served from the current version of SelfProgrammingWiki.
:Actually, this project used to be called SelfProgrammingWiki, but now it has been renamed to CommunityProgrammableWiki.
