description         lightweight DNS forwarder and DHCP server
long_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.

notes               "A startup item has been generated that will aid in\
                    starting ${name} with launchd. You must specify the\
                    path to resolv.conf. For your protection, this script\
                    is disabled by default. Execute the following command\
                    to start it, and to cause it to launch at startup:\
                    \n\nsudo port load ${name}"
