> and there are very few people who may actually find it useful. That something I generally thought about with a number of open source and personal projects I've seen, both on HN and else where. Instead of usefulness to others, I think it's more important to viewed them in the context of what experience the authors has gained and what they've learned that can be applied elsewhere. I might be wrong, but I believe that some of the diff code came from OpenBSD. It's not unrealistic that some of the modifications required to run the code on an old Macintosh could be upstreamed and improve the OpenBSD diff code.
