If you want to customize the form display, subclass this class and override the renderForm() method, you don't need to change the perform() method.
void perform( HTML_QuickForm2_Controller_Page $page, $name)
void renderForm( HTML_QuickForm2 $form)
Default behaviour is to rely on form's __toString() magic method. If you want to customize form appearance or use a different Renderer, you should override this method.
