// 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: 2001-08-21
// Email: Shane.Hill@dsto.defence.gov.au
// Reason: Remove dependancy on MFC. Code should compile on any
// platform. Tested on Windows / Linux / Irix
