#
# SYNPOSIS
#
#   unmake.sh                     [-h]
#                                 [-O <swarm|kubernetes>]
#                                 [-S <storeBase>]
#
#
# DESC
#
#   'unmake.sh' destroys a chris development instance with remote ancillary services
#   pfcon/pman running on Swarm or Kubernetes.
#
# TYPICAL CASES:
#
#   Destroy chris_dev instance with remote ancillary services running on Swarm:
#
#       unmake.sh
#
#   Destroy chris_dev instance with remote ancillary services running on Kubernetes:
#
#       unmake.sh -O kubernetes
#
# ARGS
#
#
#   -h
#
#       Optional print usage help.
#
#   -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.
