/**
 * Script to easily generate the mediawiki documentation using doxygen.
 *
 * By default it will generate the whole documentation but you will be able to
 * generate just some parts.
 *
 * Usage:
 *   php mwdocgen.php
 *
 * Then make a selection from the menu
 *
 * KNOWN BUGS:
 *
 * - pass_thru seems to always use buffering (even with ob_implicit_flush()),
 * that make output slow when doxygen parses language files.
 * - the menu doesnt work, got disabled at revision 13740. Need to code it.
 *
 *
 * @todo document
 * @addtogroup Maintenance

 * @author Ashar Voultoiz <thoane@altern.org>
