default=False? I forget if you need that.

I am still learning argparse so I am not sure either, but it seems "store_true"
takes case of the default:

http://stackoverflow.com/questions/8203622/argparse-store-false-if-unspecified

   parser.add_argument("url",
                       help="The URL to be viewed")
 
   args = parser.parse_args()
   return subprocess.call(_BuildShellCommand(args))

   sys.exit(main())
