+ * version 0.5.0
+ * Removed fftw_plan creation from inner loop of functions that use fft
+ * Added new init function xtract_init_fft() for initialisation of
+ fft_plan out-of-place. The actual plans have global scope, and are
+ freed by the library destructor.
+ * Updated Max/MSP and PD examples too reflect the above change
+ * Made the fft optimistation level a compile-time option through
+ --with-fft-optimisation flag (0 = lowest, 2 = highest).
+ * Minor fixes.
