  23  * User defined menu is good, but beer's always better
  24  * if someone wanna start hacking something, He heard...
  25  * TODO
  26  *  - enhance commands. (eg, exit, hide, list all app's member
  27  *    window and etc)
  28  *  - cache menu... dunno.. if people really use this feature :P
  29  *  - Violins, senseless violins!
  30  *  that's all, right now :P
  31  *  - external! WINGs menu editor.
  32  *  TODONOT
  33  *  - allow applications to share their menu. ] think it
  34  *    looks wierd since there still are more than 1 appicon.
  35  *
  36  *  Syntax...
  37  *  (
  38  *    "Program Name",
  39  *    ("Command 1", SHORTCUT, 1),
  40  *    ("Command 2", SHORTCUT, 2, ("Allowed_instant_1", "Allowed_instant_2")),
  41  *    ("Command 3", SHORTCUT, (3,4,5), ("Allowed_instant_1")),
  42  *    (
  43  *      "Submenu",
  44  *      ("Kill Command", KILL),
  45  *      ("Hide Command", HIDE),
  46  *      ("Hide Others Command", HIDE_OTHERS),
  47  *      ("Members", MEMBERS),
  48  *      ("Exit Command", EXIT)
  49  *    )
  50  *  )
  51  *
  52  *  Tips:
  53  *  - If you don't want short cut keys to be listed
  54  *    in the right side of entries, you can just put them
  55  *    in array instead of using the string directly.
