echo.--no-tkinter, --no-openssl
echo.
echo.Pull all sources and binaries necessary for compiling optional extension
echo.modules that rely on external libraries.
echo.
echo.The --organization option determines which github organization to download
echo.from, the --python option determines which Python 3.6+ interpreter to use
echo.with PCbuild\get_external.py.
echo.
echo.Use the -c or --clean option to remove the entire externals directory.
echo.
echo.Use the --clean-only option to do the same cleaning, without pulling in
echo.anything new.
