Largely rewritten, based on feedback on the list, on IRC, and questions
on usenet. Hopefully this is a little more what people are actually
looking for, and will steer people towards better practices. Quite a lot
of work still needs to be done, but this is the first cut, and, I think,
somewhat of an improvement. Comments solicited.
