Thanks. That was more than prompt enough for my needs. Usually when
people talk about having to reimplement something that they don't
need, it can take months.

Hmm. This turns out to be a problem for me. My graphs are not
necessarily trees. The nodes are not even guaranteed to have a common

However, it has been useful as a starting point. Based on what you
have, I've managed to whip up a suitable implementation for me. It is
rather hard-coded to my problem and probably wildly inefficient to
boot, so there probably isn't much point is posting it here.
