It's hard to say _what_ MPW is – its really sort of a mix between a CL I and a
GUI. Commands are entered as text, but it's window-oriented. I personally
don't like it (you have to hit the enter key on the numeric keypad to enter a
command – the return key just moves you to the next line!), but lots of Mac
developers seem to. I think its biggest problem is that its too radically
different from everything else people have seen.
