Computing the Neutral Zone


Have you ever add to decide, you and your colleagues, where to go for lunch? Each time, it ends up being a committee, of course.

What about just more down-to-earth matters such as making large, complex documents such as source code more legible? I have few ideas—maybe a bit wacky.
