Recently I've been discussing Unix humor with a friend and we got to the topic of the
sl command. I got the sources, compiled, installed on our development machine, and... got rather disappointed. The "official version" shows just the engine, with option to expand it to two cars.
I remember a version from a machine I had a couple years ago, that had a road crossing with barriers, a very long train, and dozens of options.
Where can I find that extended version?
