+#!/bin/sh
+#
+# $FreeBSD$

+# PROVIDE: nstxd
+# REQUIRE: DAEMON
+
+#
+# Add the following lines to /etc/rc.conf to enable nstxd:
+#
+#nstxd_domain="<your nstx domain>"
+#
+# You can disable automatic startup specifying:
+#
+#nstxd_enable="NO"
+#
+# See nstxd(8) for flags.
+#
+# The default behavour of this script is to bind nstxd to the IP 
+# of the interface with default route.
+# If you want it bind to the IP of a different interface you
+# specify this interface in /etc/rc.conf:
+#nstxd_interface="fxp0"
+# If you have static IPs or you want nstxd to listen only a
+# specific IP (e.g. 127.0.0.1) you can specify:
+#nstxd_ip="127.0.0.1"
+# in /etc/rc.conf
+# 
+# This script can also take care of the tun interface configuration
+# you simply put something like
+#nstxd_ifconfig="172.16.1.1 172.16.1.2"
+# in /etc/rc.conf to have this script automatically run
+# ifconfig with the above parameter on the device opened by nstxd.
