Avahi DNS configuration tool

 Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
 It allows programs to publish and discover services and hosts
 running on a local network with no specific configuration. For
 example you can plug into a network and instantly find printers to
 print to, files to look at and people to talk to.
 This tool listens on the network for announced DNS servers and passes
 them to resolvconf so it can use them. This is very useful on autoconfigured
 IPv6 networks.
