SUMMARY = "Avahi IPv4LL network address configuration daemon"
DESCRIPTION = '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. This tool implements IPv4LL, "Dynamic Configuration of \
IPv4 Link-Local Addresses" (IETF RFC3927), a protocol for automatic IP address \
configuration from the link-local 169.254.0.0/16 range without the need for a central \
server.'
