# Initscript for the OpenGroupware.org application server
#
# This init script can handle multiple instances of OpenGroupware.org.
# Each instance needs a subdirectory in /etc/opengroupware.org with its
# instance name. In this directory there must be an init.conf which sets
# the following variables:
# ------------------------------------------------------------------------
# USER=
# WEBUI_VERSION=
# WEBUI_PORT=
# ZIDESTORE_VERSION=
# ZIDESTORE_PORT=
# XMLRPCD_VERSION=
# XMLRPCD_PORT=
# NHSD_VERSION=
# ------------------------------------------------------------------------
# These variables specify the user that shall execute the daemons (which
# must exist and needs the necessary application defaults set), as well
# as versions and listening ports for the respective daemons.
#
# You can use the ogo-create-instance script to easily create a user with
# all necessary defaults set, along with a proper instance entry in
# /etc/opengroupware.org.
