/**
 * This is the main module class for the Gii module.
 *
 * To use Gii, include it as a module in the application configuration like the following:
 *
 * ~~~
 * return [
 *     ......
 *     'modules' => [
 *         'gii' => ['class' => 'yii\gii\Module'],
 *     ],
 * ]
 * ~~~
 *
 * Because Gii generates new code files on the server, you should only use it on your own
 * development machine. To prevent other people from using this module, by default, Gii
 * can only be accessed by localhost. You may configure its [[allowedIPs]] property if
 * you want to make it accessible on other machines.
 *
 * With the above configuration, you will be able to access GiiModule in your browser using
 * the URL `http://localhost/path/to/index.php?r=gii`
 *
 * If your application enables [[\yii\web\UrlManager::enablePrettyUrl|pretty URLs]] and you have defined
 * custom URL rules or enabled [[\yii\web\UrlManager::enableStrictParsing], you may need to add
 * the following URL rules at the beginning of your URL rule set in your application configuration
 * in order to access Gii:
 *
 * ~~~
 * 'rules' => [
 *     'gii' => 'gii',
 *     'gii/<controller>' => 'gii/<controller>',
 *     'gii/<controller>/<action>' => 'gii/<controller>/<action>',
 *     ...
 * ],
 * ~~~
 *
 * You can then access Gii via URL: `http://localhost/path/to/index.php/gii`
