  23 /* Usage Notes:
  24  * 1) Any object which added any action or action group is responsible
  25  * for removing them when done (for example, a plugin object).
  26  *
  27  * 2) Any object which merged a UI is responsible for unmerging it
  28  * when done with it (for example, a plugin object).
  29  *
  30  * 3) Avoid using EggMenuMerge object gotten by anjuta_ui_get_menu_merge(),
  31  * because AnjutaUI keeps track of all actions/action-groups added to or
  32  * removed from it and accordingly updates the required UI interfaces.
  33  * Use the EggMenuMerge object only to do things not doable by AnjutaUI.
