I found the example incomprehensible, so I looked it up in
perldoc. Anyhow, Python doesn't have it. Combining printing
various verboseness of usage messages with setting exit codes
with calling the exit function seems a little bizarre.

But I believe optparse will handle parsing arguments and printing
usage messages, though not, I think, setting verbosity levels and
exiting the program.
