Chris@45 33 *
Chris@45 34 * THIS IS A HEADER FILE, NOT A MANUAL
Chris@45 35 *
Chris@45 36 * If you want to know how to use FFTW, please read the manual,
Chris@45 37 * online at http://www.fftw.org/doc/ and also included with FFTW.
Chris@45 38 * For a quick start, see the manual's tutorial section.
Chris@45 39 *
Chris@45 40 * (Reading header files to learn how to use a library is a habit
Chris@45 41 * stemming from code lacking a proper manual. Arguably, it's a
Chris@45 42 * *bad* habit in most cases, because header files can contain
Chris@45 43 * interfaces that are not part of the public, stable API.)
