[Gsoc] License for code upload to google

[Nikhil N]

Hello all,

The time for final code update to google has arrived. I would
like to know the license to be given in the project hosting page
for google. The Zope Public License is not listed in that page.
This license being GPL compatible can it (GPL 2,GPL 3,
Lesser public license etc) be used as an option for the
uploading?.
I have noticed many Zope related projects in the same
site using these licenses (GPL 2 mostly).

Regards,
Nikhil N
