REM --                      git isn't necessary, but if it is missing, no
REM --                      commit hash will be embedded into binaries.

REM --  * python            A non-Cygwin Python 2 python.exe must be in the
REM --                      Path to run gyp.

REM --  * msbuild           msbuild must be in the Path.  It is probably
