Dear all,
due to the BSD and GPL licenses incompatibilities the cubature package
will not be included in SciPy.
Steven Johnson replied explaining that the code is directly derived from
Hintlib, and GNU GSL libraries, both of which are GPL.
The wrapper is already available in GitHub and soon I will include one link
in PyPI.
https://github.com/saullocastro/cubature
if anyone is interested.
Greetings,
Saullo
