+
+Reaction::UI::Widget::Container - Provide viewport attibutes in the current viewport
+
+=head1 DESCRIPTION
+
+This widget base class (with no corresponding layout set) will search the viewports
+attributes for those that contain L<Reaction::UI::ViewPort> classes or subclasses.
+
+These attributes will then be provided as arguments to the C<widget> fragment and
+can be rendered by their attribute name.
+
