Hey, I think that IS what I need!
I'd seen it before during some web searches but didn't pay close attention, it seemed pretty basic. But now that I look at it, it does quite a bit and the scripted layouts make a lot of sense- if I need to change something on one design, I don't want to have to redo the whole process manually.
I am having trouble importing the drill files- they're asking for a ".bor" and something else. Eagle doesn't do these, I'm confused.
