[Health] trytond.conf and tryton configuration

[Bashar]

Hi,
I installed trytond using pip and I want to connect it to a postgresql database server, but, I can't find the configuration file that I should modify to tell trytond to connect to DB server!
I searched for the trytond.conf, but, I didn't find it, so I tried to modify the /usr/local/lib/python2.6/dist-packages/trytond/config.py by setting the db host and other info, nothing works either.
Then, what shall I do in order to make tryton to connect to postgresql server?

Another question, how to install the tryton client version 2.2 using pip??

Thank You!....
