I want to play with a Wiki (ooh matron!), and there seem to be as many of them as there 
are XML syndication formats. I need:

• The basic functionality of cocoadev.com, which is the wiki I’m most familiar with.
• Maybe a revision history?
• An easy way to back-up all the “pages”.
• That’s probably about it. But feel free to suggest things.

Nothing which uses Java, please (in fact, that goes for just about anything I ever request). 
Has to be Perl/PHP/MySQL (no other database engines either). Nothing <em>too</em> simple because 
I'll want to customise it, but I also want to be able to set it up completely within half an hour.



Suggestions?
