    # This is the setuptools shim used to execute setup.py by pip.
    # Lines 2 and 3 have been added to call the above function
    # `prevent_msvc_compiling_patch` and extra escapes have been added on line
    # 5 because it is passed through another layer of string parsing before it
    # is executed.
