-# #
-# This is a helper script which will delete all resources created by #
-# NFVbench. #
-# #
-# Normally, NFVbench will clean up automatically when it is done. However, #
-# sometimes errors or timeouts happen during the resource creation stage, #
-# which will cause NFVbench out of sync with the real environment. If that #
-# happens, a force cleanup may be needed. #
-# #
-# It is safe to use the script with the resource list generated by #
-# NFVbench, usage: #
-# $ python nfvbench_cleanup.py -r /path/to/openrc #
-# #
-# Note: If running under single-tenant or tenant/user reusing mode, you have #
-# to cleanup the server resources first, then client resources. #
-# #
-# When there is no resource list provided, the script will simply grep the #
-# resource name with "nfvbench" and delete them. If running on a production #
-# network, please double and triple check all resources names are *NOT* #
-# starting with "nfvbench", otherwise they will be deleted by the script. #
-# #

-# ======================================================
-# WARNING
