nsdiff
  create an "nsupdate" script from DNS zone file differences
    The nsdiff program examines the old and new versions of a DNS zone, and
    outputs the differences as a script for use by BIND's nsupdate program.
    It provides a bridge between static zone files and dynamic updates.

    The nspatch script is a wrapper around `nsdiff | nsupdate` that checks
    and reports errors in a manner suitable for running from cron.

    The nsvi script makes it easy to edit a dynamic zone.

    If you use BIND 9.7 or 9.8, you can use nsdiff as an alternative to the
    DNSSEC "inline-signing" feature which appeared in BIND 9.9. The server
    updates the DNSSEC records dynamically, but you can continue to manage
    the unsigned static zone file as before and use `nsdiff | nsupdate` to
    push changes to the server.

    There are other situations where you have a zone which is partly dynamic
    and partly static, for example, a reverse DNS zone mostly updated by a
    DHCP server, which also has a few static entries. You can use nsdiff to
    update the static part of the zone.

  Dependencies
    To run nsdiff you need perl-5.10 or newer, and BIND version 9.7 or
    newer, specifically the dig, named-compilezone, and nsupdate utilities.
