+=== DHCP Options ===
+The hosts need not specify any fixed ip address, leaving IP address allocation to dhcpd:
+
+    [foo]
+        ethernet    = 00:11:22:33:44:55 
+    
+    $ bin/pvl.hosts-dhcp etc/hosts/dhcp1

+        hardware ethernet 00:11:22:33:44:55;
+    }
+
+=== DHCP Boot options ===
+The hosts can specify DHCP boot server/file options:
+
+    [foo]
+        ethernet    = 00:11:22:33:44:55
+        boot        = boot.lan:debian/wheezy/pxelinux.0
