    #   function to be called when gui requested. Mandatory for modules with GUI.
    # @option commandline [Yast::FunRef("boolean ()")] "initialize" function that is called before

    #        not finish with error. By default it is empty array.

    #        If array is passed it will be printed indended on multiple lines.

    #        type checking is done. It aborts if no checking is done and a value is passed on CLI.
    #        Possible values are ycp types and additionally enum and regex. For enum additional
