Hello Todd,
Thanks very much for Blitz and for allowing us to include it in SciPy
with a BSD license. I plan to go ahead and replace the GNU GPL
license with the revised BSD license. I have cced the SciPy
developer's list, so that we have a public record of your permission
for us to make this change.
Thanks,
