-Summary: A lightweight caching nameserver
-
-%description
-Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. It 
-is designed to provide DNS and, optionally, DHCP, to a small network. It can
-serve the names of local machines which are not in the global DNS. The DHCP 
-server integrates with the DNS server and allows machines with DHCP-allocated
-addresses to appear in the DNS with names configured either in each host or 
-in a central configuration file. Dnsmasq supports static and dynamic DHCP 
-leases and BOOTP for network booting of diskless machines.
