I avoid external applications if I can, because they tend to complicate things. If I can't get things fast enough in pure Python, I'd rather make a .pyd like Spanki did than use a separate program.

Look, if this can be expressed as a function call with inputs and outputs, give me the specs and I see if I can come up with something. Or point me to the part of your code that does it.
