  20  * Generic PHPTal (http://phptal.sourceforge.net/) skin
  21  * Based on Brion's smarty skin
  22  * Copyright (C) Gabriel Wicke -- http://www.aulinx.de/
  23  *
  24  * The guts of this have moved to SkinTemplate.php
  25  *
  26  * Make sure the appropriate version of PHPTAL is installed (0.7.0 for PHP4,
  27  * or 1.0.0 for PHP5) and available in the include_path. The system PEAR
  28  * directory is good.
  29  *
  30  * If PEAR or PHPTAL can't be loaded, it will try to gracefully fall back.
  31  * Turn on MediaWiki's debug log to see it complain.
