+=head1 DEPRECATED
+
+I begrudgingly made this module (and other related modules) to make porting
+from L<DBIx::Class::Schema::Versioned> relatively simple.  I will make changes
+to ensure that it works with output from L<DBIx::Class::Schema::Versioned> etc,
+but I will not add any new features to it.  It already lacks numerous features
+that the full version provides in style:
+
+=over
+
+=item *
+
+Downgrades
+
+=item *
+
+Multiple files for migrations
+
+=item *
+
+Perl files in migrations
+
+=item *
+
+Shared Perl/SQL for different databases
+
+=back
+
+And there's probably more.
+
+At version 1.000000 usage of this module will emit a warning.  At version
+2.000000 it will be removed entirely.
+
+To migrate to the New Hotness take a look at:
+L<DBIx::Class::DeploymentHandler::VersionStorage::Deprecated/THIS SUCKS> and
+L<DBIx::Class::DeploymentHandler::DeployMethod::SQL::Translator::Deprecated/THIS SUCKS>.
+
+=head1 SYNOPSIS
+
+Look at L<DBIx::Class::DeploymentHandler/SYNPOSIS>.  I won't repeat
+it here to emphasize, yet again, that this should not be used unless you really
+want to live in the past.
+
+=head1 WHERE IS ALL THE DOC?!
+
+C<DBIx::Class::DeploymentHandler::Deprecated> extends
+L<DBIx::Class::DeploymentHandler::Dad>, so that's probably the first place to
+look when you are trying to figure out how everything works.
+
+Next would be to look at all the roles that fill in the blanks that
+L<DBIx::Class::DeploymentHandler::Dad> expects to be filled.  They would be
+L<DBIx::Class::DeploymentHandler::Deprecated::WithSqltDeployMethod>,
+L<DBIx::Class::DeploymentHandler::Deprecated::WithDeprecatedVersionStorage>, and
+L<DBIx::Class::DeploymentHandler::WithReasonableDefaults>.  Also, this class
+is special in that it applies either
+L<DBIx::Class::DeploymentHandler::WithExplicitVersions> or
+L<DBIx::Class::DeploymentHandler::WithDatabaseToSchemaVersions> depending on
+your schema.
