Queue.using method.kq command line tool. Users should define an executable Python module themselves (see example here). Main reason for this was that the command line tool was not very useful: if users wanted to configure their consumers and callback functions, they had to define a configuration module and import it using the kq command line tool. This only added more room for user errors and hard-to-debug exceptions during the import, without providing much benefits over simply defining a module and calling Worker.start directly.
