Real Multi-dimensional Transforms Reference
===========================================

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