FFTW includes two standalone utility programs that deal with wisdom. We
Chris@19: merely summarize them here, since they come with their own man
Chris@19: pages for Unix and GNU systems (with HTML versions on our web site).

The first program is fftw-wisdom (or fftwf-wisdom in
Chris@19: single precision, etcetera), which can be used to create a wisdom file
Chris@19: containing plans for any of the transform sizes and types supported by
Chris@19: FFTW. It is preferable to create wisdom directly from your executable
Chris@19: (see Caveats in Using Wisdom), but this program is useful for
Chris@19: creating global wisdom files for fftw_import_system_wisdom.

The second program is fftw-wisdom-to-conf, which takes a wisdom
Chris@19: file as input and produces a configuration routine as output. The
Chris@19: latter is a C subroutine that you can compile and link into your
Chris@19: program, replacing a routine of the same name in the FFTW library, that
Chris@19: determines which parts of FFTW are callable by your program.
Chris@19: fftw-wisdom-to-conf produces a configuration routine that links
Chris@19: to only those parts of FFTW needed by the saved plans in the wisdom,
Chris@19: greatly reducing the size of statically linked executables (which should
Chris@19: only attempt to create plans corresponding to those in the wisdom,
Chris@19: however).
