If you've read this far, you deserve a prize. The first email in my mailbox with the subject "What a commit message!" (and your physical mailing address somewhere in the message) will receive a free Helix Code T-shirt mailed to anywhere within the continental United States. I cannot be held responsible for problems with email systems anywhere. This is supposed to be for fun, so please don't make a fuss if something goes wrong and your mail doesn't reach me. Find my email elsewhere in this message, and if it's been more than a few days, you're probably too late.
