   3 // Purpose:     wxMemoryConfig class: a wxConfigBase implementation which only
   4 //              stores the settings in memory (thus they are lost when the
   5 //              program terminates)

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