   4 //              stores the settings in memory (thus they are lost when the
   5 //              program terminates)

  13 /*
  14  * NB: I don't see how this class may possibly be useful to the application
  15  *     program (as the settings are lost on program termination), but it is
  16  *     handy to have it inside wxWidgets. So for now let's say that this class
  17  *     is private and should only be used by wxWidgets itself - this might
  18  *     change in the future.
