	only download fftpack.[ch]
	in fftpack.c get rid of ftnlen logical complex TRUE_ FALSE_
	turn the four instances of .5f into .5
	put c__1 and c__2 inside the functions that use them (without static)
	in the C files replace complex with fft_complex_t and delete the complex-related macros
	turn fftpack.[ch] into fftpack_float.[ch] and fftpack_double.[ch]
	in the C files change #include "fftpack.h"
	delete the "#ifndef fft_real_t" section
	in each pair replace fft_real_t with float or double
	append f or d to all functions using the regex :%s/_(/_f(/g (or :%s/_(/_d(/g)
	replace fft_complex_t with fft_complexf_t / fft_complexd_t
	in fftpack_float.c replace the functions sqrt cos sin log atan with their float equivalent also using :s//&f/g
	then turn real constants to float using :%s/\.[0-9]\+/&f/g then do :%s/FFTPACK 5.1f/FFTPACK 5.1/g
	replaces instances of pi with 3.1415927f or 3.14159265358979323846
	change the include guards in each header
	delete extern declarations of functions inside functions using /extern.*[^;]$ and Shift-N Shift-J repeatedly then :%g/[^^]extern.*/d
	make all function declarations take only one line using /^\/\* Subroutine \*\/ .*[^)]$ and Shift-N Shift-J repeatedly
	remove spaces from those joined lines using :%s/\(^\/\* Subroutine .* \*\) \(.*\)/\1\2/
	get all function prototypes using :%v/^\/\* Subroutine/d, copy them, cancel the deletion and paste them at the top
	do s/\/\* Subroutine \*\/\(.*\)/extern\1; on all of them
	add xercon to the prototypes
	remove extra blank lines using :%s/\n\n\n/\r\r/g
