ZPsycoPGDA: How to contribute

Hi,

Following my last post on this psycopg/ZPsycoPGDA ticket
<http://psycopg.lighthouseapp.com/projects/62710/tickets/142>I wille be
pleased to contribute to ZPyscopgDA
<https://github.com/psycopg/ZPsycopgDA> development.

I just have created a post on my company blog trying to describe Zope
Database Adaptaters
<http://www.makina-corpus.org/blog/understanding-zope-database-adaptaters>
(sorry for my poor english. Any typo comment is welcome, others too).

If you allow me contributing to ZPsycopgDA, here are the points I would
like to do:

* Adding documentation
* Adding unit tests
* Implementing minor changes regarding my post above in db.py and Pool.py
* Maybe putting in comments Pool.py as it is not really required,
except for its implementation of the *close* function which close
all database connections and may be very usefull: default
implementation only close database connection of the DB object of
the thread executing the method (and not for all threads DB objects)
- but I still have to check this before.

With kind regards,

Gaël.
