SUMMARY = "Lightweight, easy to configure DNS forwarder and DHCP server"
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. \
