# configuration file, it's not easy to override it or unset it (for installing
# graphite in a virtualenv for instance).
# The prefix is now set by ``setup.py`` and *unset* if an environment variable
# named ``GRAPHITE_NO_PREFIX`` is present.
# While ``setup.cfg`` doesn't contain the prefix anymore, the *unset* step is
# required for installations from a source tarball because running
# ``python setup.py sdist`` will re-add the prefix to the tarball's
# ``setup.cfg``.
