Repair roof on metal storage shed?

A recent wind storm sent a branch smack through one of the panels on the roof of my new metal storage shed, making a hole about 8" long by 6" wide. Any ideas on what I can do to repair it would be greatly appreciated. I'm not looking forward to spending another 0.00 to replace the entire thing.
Thanks for all the great answers so far! How am I going to pick one that's "the best" since they're all so good?
