resolvconf 1.63ubuntu14 (amd64 binary) in ubuntu precise

 Resolvconf is a framework for keeping up to date the system's
 information about name servers. It sets itself up as the intermediary
 between programs that supply this information (such as ifup and
 ifdown, DHCP clients, the PPP daemon and local name servers) and
 programs that use this information (such as DNS caches and resolver
 libraries).
