DNS::nsdiff - the nsdiff, nspatch, and nsvi scripts

=head1 DESCRIPTION

This is a stub module for overview documentation. There are three
scripts in the DNS::nsdiff distribution:

=over

=item B<nsdiff>

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

=item B<nspatch>

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

=item B<nsvi>

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