Ikiwiki uses markdown in plain text files, and can be configured to lock all pages and only allow specific users to edit specific pages (configuration for that would look like locked_pages => "* and !user(foo) and !user(bar) and !admin()"). It's written, unapologetically, in Perl. It is used as the wiki for projects including Dragonfly BSD, NetBSD, GNU Hurd, Monotone, Cario, etc. http://ikiwiki.info/ http://ikiwiki.info/
