Not that anyone here is in charge of your time, I think Andrei's "waste

do for the good of D. If someone else wants to write this utility,
great. But in the meantime, can we just put in the easy fix?
It's arguable whether the "easy" fix is to write a trivial utility, or to
rejigger all my build and install scripts.
In any case, it's done. Here it is, it's mostly a cut&paste from another zip
utility I wrote long ago.
