From QwikiWiki Site:

"The Simple PHP Wiki Engine QwikiWiki is driven by one core design goal: simplicity.

This design goal is codified into three key principles:
— Self Sufficiency: QwikiWiki requires only a web server and PHP.
— Zero-Edit Deployment: QwikiWiki is immediately usable "out of the box".
— Minimalist Featureset: QwikiWiki is not everything to everybody."

Note: There is no MySQL database needed for QwikiWiki!

From the WikkiTikkiTavi Site:

"WikkiTikkiTavi is a wiki engine --- it is a PHP script that runs wiki sites. Wikis are a revolutionary new form of collaboration and online community. Although there exist many WikiEngines and wikis around the world, this wiki is dedicated to the WikkiTikkiTavi and those of you who might want to use it for your wiki.

Why is it called WikkiTikkiTavi? It's a reference to the character Rikki-tikki-tavi, a mongoose whose [story] was told by Rudyard Kipling in the second of his [Jungle Books]. He was a brave mongoose, living the true mongoose spirit, the way WikkiTikkiTavi tries to live the TrueWikiSpirit."
