    """hipSOLVER is a LAPACK marshalling library, with multiple supported backends.
    It sits between the application and a 'worker' LAPACK library, marshalling
    inputs into the backend library and marshalling results back to the application.
    hipSOLVER exports an interface that does not require the client to change,
    regardless of the chosen backend. Currently, hipSOLVER supports rocSOLVER
    and cuSOLVER as backends."""
