/**
 * XCleanCommand class file.
 *
 * This command allows you to clean up various temporary data Yii and an application are generating.
 *
 * To use this command, first map it in protected/config/console.php as follows:
 * return array(
 *     'commandMap' => array(
 *         'clean'=>array(
 *             'class'=>'ext.commands.XCleanCommand',
 *             'webroot'=>'path/to/your/application/webroot'
 *         )
 *     )
 * );
 *
 * Now, under protected directory, you can run commands:
 * yiic clean
 * yiic clean cache
 * yiic clean assets
 * yiic clean runtime
