#!/bin/sh

#
# IMPORTANT: To use, do the folling:
#
# 1. Change 'NAME' variable to the name of your project. E.g. "bednets_for_nigeria"
# 2. Place this file in the TOP-LEVEL of your project, right where 'rapidsms' is
# 3. Link it into /etc/init.d e.g. > ln -s /usr/local/my_project/rapidsms-init.sh /etc/init.d/
# 4. Add it to the runlevels, on Ubuntu/Debian there is a nice tool to do this for you:
#    > sudo update-rc.d rapidsms-init.sh defaults
#
# NOTE: If you want to run multiple instances of RapidSMS, just put this init file in each project dir,
#       set a different NAME for each project, link it into /etc/init.d with _different_ names,
#       and add _each_ script to the runlevels.
