[Gsoc] [GSoC 2008] Zope 3 on Jython improvements

[Aroldo Souza-Leite]

(see also the thread
[Gsoc] MI: port Zope 3 to Jython)

Hi Georgy,


you seem to have support from the Zope side (Sidnei and Adam), but who 
would be the expert from the
Jython community?

Please specify your project, including:

- an abstract
- the project's scope
- the  project's steps
- your background and why you think you can make it

and ask Sidnei, Adam and the Jython supporter to take a critical look at it.

Regards,

Aroldo.
