*
* - dirMode: integer, the permission to be set for newly copied directories. Defaults to 0777.
* - fileMode: integer, the permission to be set for newly copied files. Defaults to the current environment setting.
* - filter: callback, a PHP callback that is called for every sub-directory and file to
* determine if it should be copied. The signature of the callback should be:
*
* ~~~
* // $path is the file/directory path to be copied
* function ($path) {
* // return a boolean indicating if $path should be copied
* }
* ~~~
* - beforeCopy: callback, a PHP callback that is called before copying each sub-directory or file.
* If the callback returns false, the copy operation for the sub-directory or file will be cancelled.
* The signature of the callback should be: `function ($from, $to)`, where `$from` is the sub-directory or
* file to be copied from, while `$to` is the copy target.
* - afterCopy: callback, a PHP callback that is called after a sub-directory or file is successfully copied.
* The signature of the callback is similar to that of `beforeCopy`.
