schema version using a diff from your I<upgrade_directory>. If a suitable diff is
not found then no upgrade is possible.
-NB: At the moment, only SQLite and MySQL are supported. This is due to
-spotty behaviour in the SQL::Translator producers, please help us by
-enhancing them. Ask on the mailing list or IRC channel for details (community details
-in L<DBIx::Class>).
+=head1 SEE ALSO
+
+L<DBIx::Class::DeploymentHandler> is a much more powerful alternative to this
+module. Examples of things it can do that this module cannot do include
+
+=over
+
+=item *
+
+Downgrades in addition to upgrades
+
+=item *
+
+Multiple sql files per upgrade/downgrade/install
+
+=item *
+
+Perl scripts allowed for upgrade/downgrade/install
+
+=item *
+
+Just one set of files needed for upgrade, unlike this module where one might
+need to generate C<factorial(scalar @versions)>
