Wow - I had to test it and didn't work. Then I remembered it would
probably work with Python2.3, and it did. But the thingamajick must work
with Python2.2.

Yes - well, command line options are not necessary a must, so I thought to
separate those from data (which *is* compulsory for the thing to work).

I admit, it is not as pretty. But the command I'm using takes lots and
lots of parameters, flags etc. and one reason in having a Python interface
is to avoid very long parameter lists (if constructor is not given any
keyword arguments, some sane defaults are assumed for them).

But thanks for the follow-up!
