Avahi glib integration library 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 library contains the interface to integrate the Avahi libraries into a GLIB main loop application, including GTK+ applications.
