+@ECHO OFF
+REM ================================================================
+REM This script installs the "vcpkg" source package manager and uses
+REM it to build the third-party libraries that git requires when it
+REM is built using MSVC.
+REM
+REM [1] Install VCPKG.
+REM     [a] Create <root>/compat/vcbuild/vcpkg/
+REM     [b] Download "vcpkg".
+REM     [c] Compile using the currently installed version of VS.
+REM     [d] Create <root>/compat/vcbuild/vcpkg/vcpkg.exe
+REM
+REM [2] Install third-party libraries.
+REM     [a] Download each (which may also install CMAKE).
+REM     [b] Compile in RELEASE mode and install in:
+REM         vcpkg/installed/<arch>/{bin,lib}
+REM     [c] Compile in DEBUG mode and install in:
+REM         vcpkg/installed/<arch>/debug/{bin,lib}
+REM     [d] Install headers in:
+REM         vcpkg/installed/<arch>/include
+REM
+REM [3] Create a set of MAKE definitions for the top-level
+REM     Makefile to allow "make MSVC=1" to find the above
+REM     third-party libraries.
+REM     [a] Write vcpkg/VCPGK-DEFS
