* to avoid unnecessary file copying;</li>
* <li>If the asset is a directory, all files and subdirectories under it will

* @param boolean $hashByName whether the published directory should be named as the hashed basename.
* If false, the name will be the hash taken from dirname of the path being published and path mtime.
* Defaults to false. Set true if the path being published is shared among
* different extensions.
* @return string an absolute URL to the published asset
* @throws Exception if the asset to be published does not exist.
