MediaWiki is a free software wiki package written in PHP, originally for
use on Wikipedia. It is now used by several other projects of the
non-profit Wikimedia Foundation and by many other wikis.
MediaWiki is designed to be run on a large server farm for a website
that gets millions of hits per day. MediaWiki is an extremely powerful,
scalable software and a feature-rich wiki implementation that uses PHP
to process and display data stored in a database, such as MySQL.
