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