Kludge to extract revision information from environment at build
time, if possible, using it to construct the software version number
that one of our users so desperately wants us to have. This is a
bit tricky because we want this to be automatic, want it to work
whether installing from binary package or git checkout or frozen
tarball, and need to be careful both to update it whenever the
revision changes and not to stomp on it when the git revision
information isn't available.
