description D.J. Bernstein's fast fourier transform library

long_description    \

        djbfft is an extremely fast library for floating-point  \

        convolution. The current version holds most of the  \

        speed records for double-precision FFTs on general  \

        purpose computers.                  \

                                    \

        djbfft provides power-of-2 complex FFTs, real FFTs at   \

        twice the speed, and fast multiplication of complex \

        arrays. Single precision and double precision are   \

        equally supported.
