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