#
# Status: this is a work in progress, under test.
#
# How to use:
#   $ bash cloudify-setup.sh [cloudify-cli|cloudify-manager] [init|setup|clean]
#   cloudify-cli: use Cloudify CLI
#   cloudify-manager: use Cloudify Manager
#   init: Initialize docker container
#   setup: Setup of Cloudify in the docker container
#   clean: Clean
