*NMKtoBAT.C - convert NMAKE.EXE output into a Windows 9x batch file

|
|
*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.
