Do you have a pre-written attribution already? I don't plan on selling my game or anything. But I do plan on sending it out to a few people and I have no idea what they're going to do with it. I just want to make sure I'm compliant. It would be handy to have one that customers could just paste in their code easily. 

And thanks for your script. It did exactly what I wanted. I almost rammed my head through a wall when I realized that Renpy didn't support inline functions.
