Playing with ArgumentParser. I can't find a way to override the -h and 
--help options so that it provides my custom help message.

   -h, --help         show this help message and exit

Here is what I am trying:

parser = argparse.ArgumentParser("csresolver.py",add_help=False)
parser.add_argument("-h","--help",
                     help="USAGE: <STDIN> | myscript.py [-exf Exception 
File]")
parser.add_argument("-e","--ext", type=str,
                     help="Exception file")
args = parser.parse_args()


The result:

$ ./myscript.py -h
usage: myscript.py [-h HELP] [-e EXT]
csresolver.py: error: argument -h/--help: expected one argument

am I missing something obvious?
