  21  * Template-filler skin base class
  22  * Formerly generic PHPTal (http://phptal.sourceforge.net/) skin
  23  * Based on Brion's smarty skin
  24  * Copyright (C) Gabriel Wicke -- http://www.aulinx.de/
  25  *
  26  * Todo: Needs some serious refactoring into functions that correspond
  27  * to the computations individual esi snippets need. Most importantly no body
  28  * parsing for most of those of course.
  29  *
  30  * PHPTAL support has been moved to a subclass in SkinPHPTal.php,
  31  * and is optional. You'll need to install PHPTAL manually to use
  32  * skins that depend on it.
