Tips and HOWTOs

This is a grab-bag of tips and HOWTOs, for various common operations and problems that we've been asked about in the past.

Treat all of these suggestions with a little caution: some of these hints are quite robustly tested, others are merely a bit of advice that has worked for one of us, at least once. That's a long way of saying: if this breaks something, you get to keep both bits, so aim to understand why the advice is saying what it's saying, rather than just typing in some random stuff off the internet.
