Well the wrappers will still be around, and they work quite well in the current
state.
I don't know if they will still be in the CVS, but they will certainly still be
available with instructions on how to build them on the SciPy site.  For those
interested, it'll hopefully be a drop in replacement.  Afterall, they work fine
now in SciPy, and I don't see the fft interfaces changing much.

see ya,
