* PROJECT : ReactOS Operating System / POSIX+ Environment Subsystem
* DESCRIPTION: POSIXW32 - A DEC VT-100 terminal emulator for the PSX subsystem
* DESCRIPTION: that runs in the Win32 subsystem.
* COPYRIGHT : Copyright (c) 2001-2002 Emanuele Aliberti
* LICENSE : GNU GPL v2
* DATE : 2001-05-05
* AUTHOR : Emanuele Aliberti <ea@iol.it>
* NOTE : This IS a Win32 program, but will fail if the PSX subsystem
* NOTE : is not installed. The PSX subsystem consists of two more
* NOTE : files: PSXSS.EXE, PSXDLL.DLL.
* WARNING : If you use this program under a real NT descendant, be
* WARNING : sure to have disabled the PSX subsystem.
