-* Extension of template class - Functions needed for compiling templates only.

-*

-* psoTFX, phpBB Development Team - Completion of file caching, decompilation

-* routines and implementation of conditionals/keywords and associated changes

-*

-* The interface was inspired by PHPLib templates, and the template file (formats are

-* quite similar)

-*

-* The keyword/conditional implementation is currently based on sections of code from

-* the Smarty templating engine (c) 2001 ispi of Lincoln, Inc. which is released

-* (on its own and in whole) under the LGPL. Section 3 of the LGPL states that any code

-* derived from an LGPL application may be relicenced under the GPL, this applies

-* to this source

-*

-* DEFINE directive inspired by a request by Cyberalien

-*

-* @package phpBB3

-* @uses template_filter As a PHP stream filter to perform compilation of templates
