 * Rewrite API: WP_Rewrite class
 *
 * @package WordPress
 * @subpackage Rewrite
 * @since 1.5.0
 

*
 * Core class used to implement a rewrite component API.
 *
 * The WordPress Rewrite class writes the rewrite module rules to the .htaccess
 * file. It also handles parsing the request to get the correct setup for the
 * WordPress Query class.
 *
 * The Rewrite along with WP class function as a front controller for WordPress.
 * You can add rules to trigger your page view and processing using this
 * component. The full functionality of a front controller does not exist,
 * meaning you can't define how the template files load based on the rewrite
 * rules.
