[PyX-devel] compatibility with apache license?

[John O. <joh...@ya...>]

Over in pyx-user we've been discussing adding "ColorBrewer" color
schemes (www.colorbrewer.org). Here's the license (below). It's
"Apache-like". If we were to use them, it's clearly "source form"
redistribution. I don't think adding the
copyright/conditions/disclaimer is a problem, or the acknowledgement,
or putting the appropriate text in the manual. The only thing I don't
know about is the compatibility of this license with the GPL.
Thoughts?
