=head1 DESCRIPTION
-B<WARNING>B This is still fairly early code, basically a hacked version of the
-Sybase Producer (thanks Sam, Paul and Ken for doing the real work ;-)
+This is currently a thin wrapper around the nextgen
+L<SQL::Translator::Generator::DDL::SQLServer> DDL maker.
=head1 Extra Attributes
* Reserved words list needs updating to SQLServer.
* Triggers, Procedures and Views DO NOT WORK
