libavahi-core7 0.6.30-0ubuntu2 (amd64 binary) in ubuntu natty

 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 library for Avahi's embeddable mDNS/DNS-SD stack.
 This can be used by embedded applications to integrate mDNS/DNS-SD
 functionality into their applications.
 .
 You should not however use this library for non-embedded applications, you
 should use libavahi-client which interacts with the avahi daemon.
