#    VM_IP_ADDRESS       public IP address of VM
#
# Note that as the script runs it will invoke "ssh", which will require the
# invoker to enter the VM account password several times. TODO: use -M and
# -S ssh flags to avoid reauthentication.
#
# This script also uses "gsutil" to copy things from the go-builder GCS bucket
# as part of the setup.
