I used dstep to generate a D interface to FFTW (Fastest 
Fourier-Transform in the West). The header for FFTW includes a 
massive 100 line (or thereabouts) macro, that basically generates 
all the function signatures.

I ran dstep on fftw3.h and although I have only tested the result 
a little, thus far it appears to have done a great job!
