and make new ones if you're interested. I just now
fixed a bug. Not only was it a dumb mistake, it was
a mistake that I already fixed once, about a year ago.
Apparently the edit got lost because I forgot to check
it in to my version control system, or some such. I
hate fixing the same bug twice.
Sorry for any confusion and/or waste of paper.
I also just now cleaned up some of the notation and added
a few more words of explanation.
