/**
* Tera_WURFL - PHP MySQL driven WURFL
*
* Tera-WURFL was written by Steve Kamerman, and is based on the
* Java WURFL Evolution package by Luca Passani and WURFL PHP Tools by Andrea Trassati.
* This version uses a MySQL database to store the entire WURFL file, multiple patch
* files, and a persistent caching mechanism to provide extreme performance increases.
*
* @package TeraWurflAdmin
* @author Steve Kamerman <stevekamerman AT gmail.com>
* @version Stable 2.1.3 $Date: 2010/09/18 15:43:21
