I'm really lame when it comes to working with arguments. I've gotten a few to work but I've also failed miserably a few times. I've looked at the documentation but yeah.. it's still an embarrassing gap in my knowledge.
Anyway, before I start stumbling around to make my Buffer~ and Groove~ respond to arguments for the file name I figure I should ask if it's even possible first. That way when it doesn't work I know if it's just my method or if I'm just trying the impossible.
