#! /bin/sh
# Generic script for running ruby scripts as daemons using
# jsvc and a java class to control the daemon.
#
# Contains common parameters and start/stop

# Things you'll need to set on a per script/daemon basis:
# SCRIPT_NAME - Path to the ruby script which creates a Daemon
# object for jsvc to control
# APP_NAME - Name of your application
#
# Things you can set:
# PROG_OPTS - Arguments to send to the program. A few defaults are appended to this.
