A shell script for deploying an Immutant archive as if it was a regular unix daemon

immutant-deploy

#!/bin/sh
#
# This allows the deploy/undeploy/redeploy of an Immutant archive as
# if it was a daemon.  The start/stop/restart methods block until that
# operation is done, so it works as init scripts are expected too.
