@license
The @license
 tag is used to indicate which license is applicable for the associated
Structural Elements
.
Syntax
@license [<url>] [name]
    Description
The @license
 tag provides the user with the name and URL of the license that is
applicable to a Structural Element
 and any of its child elements.
It is RECOMMENDED to apply @license tags ONLY to file-level PHPDocs, to prevent confusion over which license applies to any particular Structural Element .
Whenever multiple licenses apply, there MUST be one @license
 tag per applicable
license.
