# needs to do something to allow them to work. One option is to continue to
# initialize gettextutils, but with the way that Cinder has initialization
# spread out over mutltiple entry points, we'll monkey-patch
# gettextutils._(), _LI(), etc., to use our oslo.i18n versions.

# FIXME(dims): Remove the monkey-patching and update openstack-common.conf and
# do a sync with oslo-incubator to remove gettextutils once oslo-incubator
