   3  * We want to make this whole thing as seamless as possible to the
   4  * end-user. Unfortunately, we can't do _all_ of the work in the class
   5  * because A) included files are not in global scope, but in the scope
   6  * of their caller, and B) MediaWiki has way too many globals. So instead
   7  * we'll kinda fake it, and do the requires() inline. <3 PHP
