Extract a setuptools version from the git repository: adapted for PEP 386

# This file is placed into the public domain.
# Calculates the current version number. If possible, this is the
# output of “git describe”, modified to conform to the versioning
# scheme that setuptools uses. If “git describe” returns an error
# (most likely because we're in an unpacked copy of a release tarball,
# rather than in a git working copy), then we fall back on reading the
# contents of the RELEASE-VERSION file.
