# What this is: Cleanup script for a basic test to validate an OPNFV install.
#
# Prerequisites:
#   OpenStack installed.
#   Environment setting script (e.g. admin-openrc.sh) available, and executed
#   so OpenStack environment variables are setup.
#   OpenStack clients installed e.g. via setup_osc.sh in the OPNFV Models repo.
#
# How to use:
#   Install Congress test server per https://wiki.opnfv.org/copper/academy
#   $ bash ~/git/copper/tests/adhoc/smoke01.sh <openrc>
#     <openrc>: path to your openrc script
#   After test, cleanup with
#   $ bash ~/git/copper/tests/adhoc/smoke01-clean.sh 
#
# Status: this is a work in progress, under test.
