+@ECHO OFF
+REM ================================================================
+REM You can use either GCC (the default) or MSVC to build git
+REM using the GIT-SDK command line tools.
+REM        $ make
+REM        $ make MSVC=1
+REM
+REM GIT-SDK BASH windows inherit environment variables with all of
+REM the bin/lib/include paths for GCC.  It DOES NOT inherit values
+REM for the corresponding MSVC tools.
+REM
+REM During normal (non-git) Windows development, you launch one
+REM of the provided "developer command prompts" to set environment
+REM variables for the MSVC tools.
+REM
+REM Therefore, to allow MSVC command line builds of git from BASH
+REM and MAKE, we must blend these two different worlds.  This script
+REM attempts to do that.
+REM ================================================================
+REM This BAT file starts in a plain (non-developer) command prompt,
+REM searches for the "best" command prompt setup script, installs
+REM it into the current CMD process, and exports the various MSVC
+REM environment variables for use by MAKE.
+REM
+REM The output of this script should be written to a make "include
+REM file" and referenced by the top-level Makefile.
+REM
+REM See "config.mak.uname" (look for compat/vcbuild/MSVC-DEFS-GEN).
+REM ================================================================
+REM The provided command prompts are custom to each VS release and
+REM filled with lots of internal knowledge (such as Registry settings);
+REM even their names vary by release, so it is not appropriate for us
+REM to look inside them.  Rather, just run them in a subordinate
+REM process and extract the settings we need.
+REM ================================================================
+REM
+REM Current (VS2017 and beyond)
+REM -------------------
+REM Visual Studio 2017 introduced a new installation layout and
+REM support for side-by-side installation of multiple versions of
+REM VS2017.  Furthermore, these can all coexist with installations
+REM of previous versions of VS (which have a completely different
+REM layout on disk).
+REM
+REM VS2017 Update 2 introduced a "vswhere.exe" command:
+REM https://github.com/Microsoft/vswhere
+REM https://blogs.msdn.microsoft.com/heaths/2017/02/25/vswhere-available/
+REM https://blogs.msdn.microsoft.com/vcblog/2017/03/06/finding-the-visual-c-compiler-tools-in-visual-studio-2017/
+REM
+REM VS2015
+REM ------
+REM Visual Studio 2015 uses the traditional VcVarsAll.
+REM
+REM Earlier Versions
+REM ----------------
+REM Currently unsupported.
+REM
+REM ================================================================
+REM Note: Throughout this script we use "dir <path> && <cmd>" rather
+REM than "if exist <path>" because of script problems with pathnames
+REM containing spaces.
+REM ================================================================
+
+REM Sanitize PATH to prevent git-sdk paths from confusing "wmic.exe"
+REM (called internally in some of the system BAT files).
+SET PATH=%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;
