Looking at http://comphys.unibas.ch/SOFTWARE/FFT/fft3d.f90 and the
BigDFT code at [1], it seems S. Goedecker has GPL-licensed (v2 or later)
that code later on.

So I guess it would be, for all practical purposes, fine to just add the
regular copyright boilerplate and the CP2K copyright, removing the
"Commercial use is prohibited without the explicit permission of the
author." part, but keeping his copyright line.


Best Regards,

Michael
