 * Ok, glad you are here
 * first we get a config instance, and set the settings
 * $config = HTMLPurifier_Config::createDefault();
 * $config->set('Core.Encoding', $this->config->get('purifier.encoding'));
 * $config->set('Cache.SerializerPath', $this->config->get('purifier.cachePath'));
 * if ( ! $this->config->get('purifier.finalize')) {
 *     $config->autoFinalize = false;
 * }
 * $config->loadArray($this->getConfig());
 *
 * You must NOT delete the default settings
 * anything in settings should be compacted with params that needed to instance HTMLPurifier_Config.
