/**
 * Allows you to flush cache.
 *
 * see list of available components to flush:
 *
 *     yii cache
 *
 * flush particular components specified by their names:
 *
 *     yii cache/flush first second third
 *
 * flush all cache components that can be found in the system
 *
 *     yii cache/flush-all
 *
 * Note that the command uses cache components defined in your console application configuration file. If components
 * configured are different from web application, web application cache won't be cleared. In order to fix it please
 * duplicate web application cache components in console config. You can use any component names.
 *
 * APC is not shared between PHP processes so flushing cache from command line has no effect on web.
 * Flushing web cache could be either done by:
 *
 * - Putting a php file under web root and calling it via HTTP
 * - Using [Cachetool](http://gordalina.github.io/cachetool/)
