// DESCRIPTION
//
//  This program does a simple compression of a file to a memory buffer.
//  It uses the raw compression function, instead of using an archive
//  or ALCompressedObject as its target.  This is the sort of code you
//  would use if you were compressing or expanding from your own types
//  of proprietary files.
//
// REVISION HISTORY
//
//  February 1, 1996  2.0A  : Second release
