Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
15-Aug-1991 JohnRo
Implement downlevel NetFile APIs.
20-Nov-1991 JohnRo
Removed NT dependencies to reduce recompiles.
13-Dec-1991 JohnRo
Quiet debug output by default.
