long_desc="
 FFTW is a free collection of fast C routines for computing the Discrete
 Fourier Transform in one or more dimensions. It includes complex, real,
 symmetric, and parallel transforms, and can handle arbitrary array sizes
 efficiently. FFTW is typically faster than other publically-available FFT
 implementations, and is even competitive with vendor-tuned libraries."
