I’d been passively hoping for a command-line image spriting tool for a while, so this is great.

But I don’t need it anymore. I’ve discovered @chriseppstein’s fabulous Compass. Now you don’t even need a command line — you can sprite directly in your (s)css!

(This version isn’t stable yet, so install with `gem install compass --pre`. Actually, not sure if this feature is stable yet or not, but the beta version of Compass rocks.)
