+  The Fastest Fourier Transform in the West 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. It is becoming the FFT library of choice for most
+  applications. Benchmarks, performed on a variety of platforms, show
+  that FFTW's performance is typically superior to that of other
+  publicly available FFT software.
