The manual SHELL?... is that an opensource project?...

Hi All, I started to build a project for some people and they wanted it to be "kind of like a wiki" but they wanted the "authoritative version" to be only editable by the few, but also wanted to allow comments by just about anyone.... .... and I thought of the PHP Maunual. It is exactly that. Was the manual built within something that is its own opensource project in PHP? Links are fine -- I looked at the credits and etc before emailing here, but I might not have been looking at the right thing or didn't know what to look for. Thanks in advance. -- Brad Brad Lowry IT Lead USC School of Dentistry 925 W 34th Street Los Angeles, CA 90089 email: bradlowr@usc.edu work: 213.740.6126 cell: 213.842.8888
