%description
KISS FFT - A mixed-radix Fast Fourier Transform based up on the 
principle, "Keep It Simple, Stupid."

There are many great fft libraries already around. Kiss FFT is
not trying to be better than any of them. It only attempts to be
a reasonably efficient, moderately useful FFT that can use fixed
or floating data types and can be incorporated into someone's C
program in a few minutes with trivial licensing.
