   3  * Generate class and file reference documentation for MediaWiki using doxygen.
   4  *
   5  * If the dot DOT language processor is available, attempt call graph
   6  * generation.
   7  *
   8  * Usage:
   9  *   php mwdocgen.php
  10  *
  11  * KNOWN BUGS:
  12  *
  13  * - pass_thru seems to always use buffering (even with ob_implicit_flush()),
  14  * that make output slow when doxygen parses language files.
  15  * - the menu doesnt work, got disabled at revision 13740. Need to code it.
