<description>
<p>The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf
architecture (also known as "Rendezvous" or "Bonjour"). The daemon
registers local IP addresses and static services using
mDNS/DNS-SD and provides two IPC APIs for local programs to make
use of the mDNS record cache the avahi-daemon maintains. First
there is the so called "simple protocol" which is used
exclusively by avahi-dnsconfd (a daemon which configures unicast
DNS servers using server info published via mDNS) and nss-mdns
(a libc NSS plugin, providing name resolution via mDNS). Finally
there is the D-Bus interface which provides a rich object
oriented interface to D-Bus enabled applications.</p>
<p>Upon startup avahi-daemon interprets its configuration file
<file>@pkgsysconfdir@/avahi-daemon.conf</file> and reads XML
fragments from <file>@servicedir@/*.service</file> which may
define static DNS-SD services. If you enable
<opt>publish-resolv-conf-dns-servers</opt> in
<file>avahi-daemon.conf</file> the file
<file>/etc/resolv.conf</file> will be read, too.</p>
