[Python-legal-sig] Include BSD code into Python?

[Victor Stinner]

Hi,

I would like to reuse code from the libcfu project in Python:
http://sourceforge.net/projects/libcfu/

Here is the license:

Can you confirm me that this BSD 3-clauses license is compatible with
the Python license?

I'm using libcfu hash table in my new tracemalloc module (PEP 454):
http://hg.python.org/features/tracemalloc/file/ac693c811b1d/Modules/_tracemalloc.c#l1

I heavily modified the code of the hash table, but I would like to
keep the original author and the copyright notice.

I contacted the author (Don Owens aka regexguy):

don> I believe so.  It basically allows you to use the code any way you want,
don> as long as you include the copyright notice and attribution in the code.
