Please go and discuss the project and the world's attitude and policy towards copyright

I need *technical* feedback about the API. I would also like to have someone take a quick
look at the implementation, although I'm confident its okay and as optimal as a generic
software implementation could be. Accuracy-wise its slightly better than libfftw3f, due to
the use of reordering for nptwo transform direction and the compound 15-point FFT
(less operations due to the lack of inter-stage twiddles).
Can provide a benchmarking test program on IRC.
