This directory contains FFT routines adapted from the GNU Scientific
Library (GSL).  The routines were written by Brian Gough
(bjg@vvv.lanl.gov).  The original GSL may be downloaded from:

These files are covered by the GNU General Public License, as
described in the COPYING file in this directory.  If you distribute
this code along with the benchmark, you must abide by the terms of
this license.

All of the code derived from the GSL (and thus covered by the GNU
license) is located in this directory (the gsl/ directory).

We have made some changes to the code from the GSL in order to
incorporate it into the benchmark.  The changes that we made are as
follows:

 * Modified gsl_complex.h to include fftw.h and define a "real"
   type which is an alias of fftw's FFTW_REAL type.

 * Changed all files to use "real" instead of "double".

 * Changed #include <gsl_*> to #include "gsl_*"

 * Deleted the Makefiles, since we don't use them.

 * Moved test programs into the gpl/tests/ directory.
