%description
hipFFT is an FFT marshalling library. Currently, hipFFT supports
the rocFFT backends

hipFFT exports an interface that does not require the client to
change, regardless of the chosen backend. It sits between the
application and the backend FFT library, marshalling inputs into
the backend and results back to the application.
