For example, the `help` command * is implemented using the `HelpController` class. * * To run the console application, enter the following on the command line: * * ~~~ * yiic <route> [--param1=value1 --param2 ...] * ~~~ * * where `<route>` refers to a controller route in the form of `ModuleID/ControllerID/ActionID` * (e.g. `sitemap/create`), and `param1`, `param2` refers to a set of named parameters that * will be used to initialize the controller action (e.g. `--since=0` specifies a `since` parameter * whose value is 0 and a corresponding `$since` parameter is passed to the action method). * * A `help` command is provided by default, which lists available commands and shows their usage. * To use this command, simply type: * * ~~~ * yiic help * ~~~ * * @author Qiang Xue <qiang.xue@gmail.com> * @since 2.0 */ class Application extends \yii\base\Application { /** * @var string the default route of this application.
