You can already do this with CmdArgs. If you use cmdArgsMode/process
it returns a structure populated to say what to do next (i.e. display
a help message), but you are welcome to do something different, or do
what it says in a different way. However, I can see some people might
want to remove help entirely, so I'll try and find a balance.

Thanks, Neil
