+// IniFile.cpp:  Implementation of the CIniFile class.
+// Written by:   Adam Clauss
+// Email: cabadam@houston.rr.com
+// You may use this class/code as you wish in your programs.  Feel free to distribute it, and
+// email suggested changes to me.
+//
+// Rewritten by: Shane Hill
+// Date:         21/08/2001
+// Email:        Shane.Hill@dsto.defence.gov.au
+// Reason:       Remove dependancy on MFC. Code should compile on any
+//               platform.
