/***
*NMKtoBAT.C - convert NMAKE.EXE output into a Windows 9x batch file
*
* Copyright (c) 1995-2001, Microsoft Corporation. All rights reserved.
*
*Purpose:
* The makefiles provided with the Microsoft Visual C++ (C/C++) Run-Time
* Library Sources generate commands with multiple commands per line,
* separated by ampersands (&). This program will convert such a
* text file into a batch file which can be executed by the Windows 9x
* command interpreter (COMMAND.COM) which does not recognize multiple
* commands on a single line.
*
