That's not the command-line argument style that optparse models. It
should be:

    command_name [options] <arg1> <arg2>

In other words, the options (optionally) appear before the non-option
arguments. This is the convention followed by most command-line tools,
and it's what users expect.

There are other command-line parser modules (e.g. argparse), perhaps
you can look to them for different functionality.
