-/* Palm OS does not have good dynamic menu support. About all you can do with
- * the standard API calls is to add new items to an existing drop-down menu and
- * hide/show items in a drop-down menu. It is impossible to add, hide, or
- * change the label on a drop-down menu.
- *
- * The easiest and simplest way around this limitation is to modify the Palm OS
- * MenuBarType structure directly. This gives limited ability to change the
- * label on a drop-down menu. I have not been able to find a safe way to add,
- * delete, or resize drop-down menus in OS 6.
- *
- * The following routine attempt to work around these limitations present in the
- * Palm OS API to provide limited dynamic menu support. This solution is far
- * from perfect, but the only other option is to wait for PalmSource to add full
- * dynamic menu support, or to recreate the Palm OS menu system from scratch.
- *
- * This system is limited in that no more than 4 drop-down menus are allowed per
- * menu bar, and the label for each drop-down menu is limited to 8 characters of
- * text. However, this menu system should work for most applications.
- *
- * Basically the menu routines select one of four menu bars, depending on
- * whether or not the requested menu bar has one, two, three, or four drop-down
- * menus.
- *
- * These four "template" menu bars contain one, two, three, or four drop-down
- * menus. Each menu has a dummy menu item attached to it to allow the Palm OS
- * MenuAddItem function to add the real items.
- *
- * The labels on the drop-down menus are then replaced with the labels of the
- * real menus.
- *
- * The menu is then attached to the active window and the MenuAddItem API
- * function is called to add the items to each drop-down menu. Finally,
- * MenuHideItem is called to remove the dummy items from each drop-down menu.
