/***************************************************************************************
Analyze - Sample 1
Copyright (C) 2000-2001 by Matthew T. Ashland   All Rights Reserved.
Feel free to use this code in any way that you like.

This example opens an APE file and displays some basic information about it. To use it,
just type Sample 1.exe followed by a file name and it'll display information about that
file.

Notes for use in a new project:
	-you need to include "MACLib.lib" in the included libraries list
	-life will be easier if you set the [MAC SDK]\\Shared directory as an include 
	directory and an additional library input path in the project settings
	-set the runtime library to "Mutlithreaded"

WARNING:
	-This class driven system for using Monkey's Audio is still in development, so
	I can't make any guarantees that the classes and libraries won't change before
	everything gets finalized.  Use them at your own risk.
