# get-pip.py mirror is available, PIP_GET_PIP_URL can be set to that
# mirror in local.conf to avoid download timeouts.
# Example:
# PIP_GET_PIP_URL="http://local-server/get-pip.py"
#
# Note that if get-pip.py already exists in $FILES this script will
# not re-download or check for a new version. For example, this is
# done by openstack-infra diskimage-builder elements as part of image
# preparation [1]. This prevents any network access, which can be
# unreliable in CI situations.
