This is the WIDE implementation of DHCP (Dynamic Host Configuration Protocol)
server, relay agent, and client.  DHCP, which is defined by RFCs 1534, 1542,
2131, and 2132, provides information to a computer over a network about the
configuration of that network.
To use DHCP, configure your kernel with the following line added to your kernel
configuration file (/usr/src/sys/i386/conf/<YourMachine>):
	pseudo-device	bpfilter	4	#Berkeley packet filter
and make bpf devices in your /dev directory: /dev/bpf[1-3]:
	cd /dev && ./MAKEDEV bpf1 bpf2 bpf3
Without the relay agent, the dhcpdb.relay file is needed.  The DHCP
client(dhcpc) in this port supports dynamically changing /etc/resolv.conf and
hostname via DHCP infomation.
		  o `-r' is recreate /etc/resolv.conf
		         (resolv.conf file is overwritten.)
		  o `-n' is reset HOSTNAME
