libavahi-glib-dev 0.6.22-2ubuntu4 (lpia binary) in ubuntu intrepid

 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 package contains the development headers for the interface
 to integrate the Avahi libraries into a GLIB main loop application,
 including GTK applications.
