-# 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:                                                            #

-# 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.     #
