Major Upgrade - added very detailed configs for many scenarios, with lots of examples. The server is now fully functional for an authoritative master and a recursive/forwarding cacher. You can still mount over the /etc/bind and /var/bind directories and override everything yourself. This should help many users who did not know where to start with bind.
