SMF Manifest and shell script for SmartOS to register common, active DNS-SD services.

dnssd-register.sh

#!/bin/bash

# dnssd-register.sh -- Register common services for SmartOS
#
# This is really only useful for people who run SmartOS on a LAN segment
# with workstations. E.g., your house.
#
# This script scans for common locally listening services and registers
# them with mDNS/DNS-SD/Bonjour.
