drive a desktop app from python?

[Tim Arnold]

Hi, I don't even know what to google for on this one. I need to drive a 
commercial desktop app (on windows xp) since the app doesn't have a batch 
interface.  It's intended to analyze one file at a time and display a 
report.

I can get the thing to write out the report an html browser, but I have 
thousands of files I need it to analyze every night.

Is there any lib or recipe(s) for doing something like this via python?

thanks,
