Register a mDNS/DNS-SD alias name for your computer using the Avahi daemon
#! /usr/bin/env python2
'''
Register a mDNS/DNS-SD alias name for your computer using the Avahi daemon
This script will register an alternate CNAME alias besides your hostname,
which could be useful for ex. when serving several http virtual hosts to
your ffriends on the local network and you don't want to make them configure
their /etc/hosts.
Why a CNAME? You could also publish your current address with avahi-publish-address
