/**
 | 
						|
 * Allows you to combine and compress your JavaScript and CSS files.
 | 
						|
 *
 | 
						|
 * Usage:
 | 
						|
 *
 | 
						|
 * 1. Create a configuration file using the `template` action:
 | 
						|
 *
 | 
						|
 *    yii asset/template /path/to/myapp/config.php
 | 
						|
 *
 | 
						|
 * 2. Edit the created config file, adjusting it for your web application needs.
 | 
						|
 * 3. Run the 'compress' action, using created config:
 | 
						|
 *
 | 
						|
 *    yii asset /path/to/myapp/config.php /path/to/myapp/config/assets_compressed.php
 | 
						|
 *
 | 
						|
 * 4. Adjust your web application config to use compressed assets.
 | 
						|
 *
 | 
						|
 * Note: in the console environment some [path aliases](guide:concept-aliases) like `@webroot` and `@web` may not exist,
 | 
						|
 * so corresponding paths inside the configuration should be specified directly.
 | 
						|
 *
 | 
						|
 * Note: by default this command relies on an external tools to perform actual files compression,
 | 
						|
 * check [[jsCompressor]] and [[cssCompressor]] for more details.
 | 
						|
 *
 | 
						|
 * @property \yii\web\AssetManager $assetManager Asset manager instance. Note that the type of this property
 | 
						|
 * differs in getter and setter. See [[getAssetManager()]] and [[setAssetManager()]] for details.

     * You can specify the name of the output compressed file using 'css' and 'js' keys:
 | 
						|
     * For example:
 | 
						|
     *
 | 
						|
     * ```php
 | 
						|
     * 'app\config\AllAsset' => [
 | 
						|

 | 
						|

 | 
						|
     * ]
 | 
						|
     * ```
 | 
						|
     *
 | 
						|
     * File names can contain placeholder "{hash}", which will be filled by the hash of the resulting file.
 | 
						|
     *
 | 
						|
     * You may specify several target bundles in order to compress different groups of assets.
 | 
						|
     * In this case you should use 'depends' key to specify, which bundles should be covered with particular
 | 
						|
     * target bundle. You may leave 'depends' to be empty for single bundle, which will compress all remaining
 | 
						|
     * bundles in this case.
 | 
						|
     * For example:
 | 
						|
     *
 | 
						|
     * ```php
 | 
						|
     * 'allShared' => [
 | 
						|
