# This is a cleanup script for installation of Congress on the OPNFV Controller
# node as installed via JOID or Apex (Fuel and Compass not yet verified).
# Presumably something has failed, and any record of the Congress feature
# in OpenStack needs to be removed, so you can try the install again.
# This is script 2 of 2 for installation of OpenStack Congress.
# Prerequisites: 
# - OpenStack base deployment.
# Usage:
# $ bash clean_congress.sh <target> <user>
#   <target>: IP/hostname where Congress is being installed
#             localhost: install in a docker container on the current host
#             IP address: install in a virtualenv
#   <user>: IP/hostname where Congress is being installed
# 
target=$1
user=$2
