PDL-FFTW
========

This module provides bindings to the FFTW version 2.x library
(the original API).  It was originally part of the PDL distribution
As of Aug 2013, it has been spun off into its own distribution for
improved portability and to make way for FFTW3.


DEPENDENCIES

This module requires these other modules and libraries:

This module needs the perl PDL module and the FFTW library
version 2 installed.  FFTW is a free C FFT library including

for how to build the module.

This module is not compatible with the current FFTW3 API.
