В чем разница между vcvarsall.bat и bin/vcvars32.bat?

Question

В каталоге, C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC, Ther два .bat файлы:

• ./vcvarsall.bat
• bin/vcvars32.bat

Запуск каждый из них дает такое же сообщение:

Настройка среды для использования Microsoft Инструменты Visual Studio 2010 x86.

Какова цель каждого, и когда я буду использовать каждый из них?

Ниже содержимое каждого файла летучей мыши:

Вы бы использовать vcvarsall.bat, как он определяет, на основе значения параметра, которое вы передаете, в каком vcvars * .bat-файле для вызова.

Отрывок из vcvarsall.bat:

:x86 
if not exist "%~dp0bin\vcvars32.bat" goto missing 
call "%~dp0bin\vcvars32.bat" 
goto :eof
