WhatDoIKnow.org has a nice writeup with comments on the topic. By the way, you can do this same effect without code but it seems like a lot more work to me.
I only need to do this about once a year and I always end up spending an hour going, “how the frak did I do that last year.” Now next year when I need to do this again I can just search my own blog. If I remember that I wrote about this. :-)
