+mDNS/DNS-SD responder that allows for service discovery and
+"zero-configuration" host name lookups (see @uref{http://avahi.org/}).
+
+If @var{host-name} is different from @code{#f}, use that as the host name to
+publish for this machine; otherwise, use the machine's actual host name.
+
+When @var{publish?} is true, publishing of host names and services is allowed;
+in particular, avahi-daemon will publish the machine's host name and IP
+address via mDNS on the local network.
+
+When @var{wide-area?} is true, DNS-SD over unicast DNS is enabled.
+
+Boolean values @var{ipv4?} and @var{ipv6?} determine whether to use IPv4/IPv6
