Here's my failed example:

I have a script which requires a variable S (which in this case is a Zip
code). It previously got this from a valueDialog. I commented out the
valueDialog line.

I tried to run it with

scribus -g -py postnet.py --python-arg -S 40207

and when it runs it tells me there is no value for S.

Maybe I don't understand what a 'python-arg' is.
