Build a script to install all modules dependency
When you nclone all the trytond modules and you install the trytond server for developing (with python setup.py develop) all the modules dependencies are not installed so they should be manually installed.
In Tub we discussed two possible solutions:
1. Create a install-module-dependencies script in trytond which loops on the modules directory and executes the python setup.py develop for every module.
2. Create a tryton-module package that depends on all modules and that should be installed using trydevpi as dependency.
For me the first one is the easier to mantain.
Also we should modify the website to document how to install all the dependencies.
