* Adding per-host dhcp option support
 * Adding dhcpv6 client-id support
 * Adding support for DNS round robin configurations
     This is is a manual record entry into the host_list.xml file
     which assumes that one or more hosts exist to round-robin between:
     <host>
       <hostname>host.example.com</hostname>
       ...
       <dnsrr>
         <hostname>host1.example.com</hostname>
         <hostname>host2.example.com</hostname>
       </dnsrr>
     </host>
     This will choose optimal resolution based on network view. If only
     one host is available on a network then only that one will be in the
     resolution.
 * Adding strange location of svn support under helper scripts.
 * Modify add.py:
     support aaaa records
     require --replace flag when updating existing hosts (safer default)
 * Create several helpers (etc_ethers/etc_hosts) for quick grep style lookups
 * Allow multiple default mx values for a network
