This realfft(3) package does Cooley-Tukey fast Fourier transform on an arbitrary
number of real samples.  It uses fft(3) for the actual complex transform.

How to make the stuff:
	make		- create library "realfft.a"
	make fft.man	- nroff manual page "realfft.3" into "realfft.man"
	make print	- print source and "realfft.man"

Programs using realfft(3), should be loaded (ld(1)) with libraries "realfft.a",
"../complex/fft.a" and "/usr/lib/libm.a".  The package also uses malloc(3) of
the standard C-library.
