This file helps to compute a version number in source trees obtained
from git-archive tarball (such as those provided by githubs
download-from-tag feature). Distribution tarballs (build by setup.py
sdist) and build directories (produced by setup.py build) will contain
a much shorter file that just contains the computed version number.

The Firedrake package version now includes the git revision as returned
by  git describe --tags --dirty --always
