// IniFile.cpp:  Implementation of the CIniFile class.
// Written by:   Adam Clauss
// Email: cabadam@tamu.edu
// 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. Tested on Windows/Linux/Irix
