/*
* class ALOpenInputFile
*
* DESCRIPTION
*
* ALCopyEngine is a full fledged compression engine. It just
* copies files from input to output, instead of doing something
* exciting like making them smaller. Its principal virtue is that it
* is very fast. If you are packing a bunch of files into an archive,
* and don't particularly need to compress them, you can use an instance of
* ALCopyEngine and get your work done quickly.
*
* DATA MEMBERS
*
* None.
*
* MEMBER FUNCTIONS
*
* ALCopyEngine() : The one and only constructor.
* ~ALCopyEngine() : The virtual destructor.
* operator new() : Memory allocation operator, only used when the
* library is in a DLL.
* Compress() : The virtual compression function.
* Decompress() : The virtual decompression function.
*
* REVISION HISTORY
*
* May 26, 1994 1.0A : First release
*
