+// Name:        wx/memconf.h
+// Purpose:     wxMemoryConfig class: a wxConfigBase implementation which only
+//              stores the settings in memory (thus they are lost when the
+//              program terminates)
+// Author:      Vadim Zeitlin
+// Modified by:
+// Created:     22.01.00

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