I know that the license of pywordnet is here  and it seems to be an "Artistic License"; but I'm not sure if it's really that, or a modification. Could you please specify in the license page what's the specific license? A title in the page saying "Artistic License 1.0" or "Artistic License 2.0" would be enough.
Also related to the license thing... I'm using pywordnet inside my GPL software, and ohloh says it's incompatible . Do you know if the pywordnet license is really GPL compatible or not? I've read that "Artistic License 1.0" is incompatible while "Artistic License 2.0" is GPL compatible; would you think about changing the license to v2.0? Thanks in advance!
