Real One-dimensional Transforms Reference
=========================================

   The one-dimensional real routines are generally prefixed with
`rfftw_'. (1)  Programs using RFFTW should be linked with `-lrfftw
-lfftw -lm' on Unix systems, or with the RFFTW, the FFTW, and the
standard math libraries in general.

   (1) The etymologically-correct spelling would be `frftw_', but it is
hard to remember.
