+/***************************************************************************************
+Decompress - 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 illustrates using MACDLib.lib and the simple IAPESimple class to verify
+or decompress a file. (verify and decompress work the same, except that verify doesn't
+have an output file)  Also, shows how to use a callback to display the progress.
+
+General Notes:
+	-the terminology "Sample" refers to a single sample value, and "Block" refers 
+	to a collection	of "Channel" samples.  For simplicity, MAC typically uses blocks
+	everywhere so that channel mis-alignment cannot happen.
+
+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.
