 * A tailor-made menu for displaying all necessary information about an

 * options dialog for modifying all options pertaining to the plugins.<p>
 *
 * Your applicaiton can add a <code>PluginMenu</code> to its menu bar as
 * follows:
 * <pre>
 *   menuBar.add(new PluginMenu(app));
 * </pre>
 * The plugin menu will take care of its menu items itself, and will be
 * localized (except for the submenus, which are the individual plugins'
 * responsibilities).
