+Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX
+relationship names and singularized Results, unless you're overwriting an
+existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in
+which case the backward compatible RelBuilder will be activated, and
+singularization will be turned off.

+
+    naming => 'v5'
+
+will disable the backward-compatible RelBuilder and use
+the new-style relationship names along with singularized Results, even when
+overwriting a dump made with an earlier version.
+
+The option also takes a hashref:
+
+    naming => { relationships => 'v5', results => 'v4' }
+
+The values can be:
