- It was written by [Lonny Gomes](https://twitter.com/lonnygomes) and [James Stephenson](https://plus.google.com/u/0/103174459258175070784/about) but we haven't maintained it for some time. We recently saw an old tarball of the code floating around the net and thought it would be good to start maintaining the codebase again.
