Check it out:
def ParseAndRun():
crazy_external_function_that_might_exit()
# Argparse blah blah
parser.parse_args()
if __name__ == "__main__":
try:
ParseAndRun()
except SystemExit:
# was it crazy_external_function_that_might_exit or an argparse error?
I know this might come through as bike shedding but it's just
customary python that every module have it's own exception types as to
not mix them up with others.
