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.
