Make sure you know whether or not you can use other parameters in your command line. In my assignment, I can't.
See
thread NX: Spec Confusion that talks about both a Client and Server side GUI.
this thread My plan is to have a dialog box similar to the one in Max's book to allow the user to pick what GUI they want to run. (in the book he was picking between local/network, but I do that on command line for my assignment)
