   3  * Script to easily generate the mediawiki documentation using doxygen.
   4  *
   5  * By default it will generate the whole documentation but you will be able to
   6  * generate just some parts.
   7  *
   8  * Usage:
   9  *   php mwdocgen.php
  10  *
  11  * Then make a selection from the menu
  12  *
  13  * KNOWN BUGS:
  14  *
  15  * - pass_thru seems to always use buffering (even with ob_implicit_flush()),
  16  * that make output slow when doxygen parses language files.
  17  * - the menu doesnt work, got disabled at revision 13740. Need to code it.
  18  *
