#
# SYNPOSIS
#
#   unmake.sh                     [-h] [-N] \
#                                 [-F <swift|filesystem|fslink|zipfile>]   \
#                                 [-O <swarm|kubernetes>]  \
#                                 [-S <storeBase>]
#
#
# DESC
#
#   'unmake.sh' destroys a pfcon development instance running on Swarm or Kubernetes.
#
# TYPICAL CASES:
#
#   Destroy pfcon dev instance on Swarm:
#
#       unmake.sh
#
#   Destroy pfcon dev instance operating in-network on Swarm using Swift storage:
#
#       unmake.sh -N -F swift
#
#   Destroy pfcon dev instance operating in-network on Swarm using mounted filesystem
#   with ChRIS links storage:
#
#       unmake.sh -N -F fslink
#
#   Destroy pfcon dev instance operating in-network on Swarm using mounted filesystem storage:
#
#       unmake.sh -N -F filesystem
#
#   Destroy pfcon dev instance on Kubernetes:
#
#       unmake.sh -O kubernetes
#
# ARGS
#
#
#   -h
#
#   -N
#
#       Explicitly set pfcon to operate in-network mode (using a swift storage instead of
#       a zip file).
#
#       Optional print usage help.
#
#   -F <swift|filesystem|fslink|zipfile>
#
#       Explicitly set the storage environment. This option must be swift or filesystem
#       for pfcon operating in-network mode. For pfcon operating in out-of-network mode
#       it must be set to zipfile (default).
#
#   -O <swarm|kubernetes>
#
#       Explicitly set the orchestrator. Default is swarm.
#
#   -S <storeBase>
#
#       Explicitly set the STOREBASE dir to <storeBase>. This is the remote ChRIS
#       filesystem where pfcon and plugins share data.
