[Twisted-Python] Documentation Question

[Steven Bauer]

Being new to twisted I may be lacking a clue, but finding the
proper arguments to twisted.application.internet.UDPServer()
was a major pain in the butt.  

Only by looking at the code could I find all the valid arguments and
that took a lot of tracing because the valid arguments are determined by
listenudp() it seems.

Is their an easier way or is it always frustrating to determine the
acceptable arguments to an init function? 

Thanks,
Steve
