%description
FFTW is a C subroutine library for computing the Discrete Fourier Transform
(DFT) in one or more dimensions, of both real and complex data, and of
arbitrary input size. We believe that FFTW, which is free software, should
become the FFT library of choice for most applications. Our benchmarks,
performed on on a variety of platforms, show that FFTW's performance is
typically superior to that of other publicly available FFT software.

This package contains header files and development libraries needed to
develop programs using the FFTW fast Fourier transform library.
