%description
nss-mdns is a plugin for the GNU Name Service Switch (NSS)
functionality of the GNU C Library (glibc) providing host name
resolution via Multicast DNS (aka Zeroconf, aka Apple Rendezvous, aka
Apple Bonjour), effectively allowing name resolution by common
Unix/Linux programs in the ad-hoc mDNS domain .local.

nss-mdns provides client functionality only, which means that you have
to run a mDNS responder daemon seperately from nss-mdns if you want to
register the local host name via mDNS. I recommend Avahi.

By default nss-mdns tries to contact a running avahi-daemon for
resolving host names and addresses and making use of its superior
record cacheing.
