/**
 * Phing subclass of the phpDocumentor_setup class provided with PhpDocumentor to work around limitations in PhpDocumentor API.
 * 
 * This class is necessary because phpDocumentor_setup does not expose a complete API for setting configuration options.  Because
 * this class must directly modify some "private" GLOBAL(!) configuration variables, it is liable to break if the PhpDocumentor
 * internal implementation changes.  Obviously this is far from ideal, but there's also no solution given the inflexibility of the
 * PhpDocumentor design.
