Massimo, I know that the primary development of web2py uses hg, however a small change to the web2py launchpad project would make it easier to install with bzr.
Please assign the lp:~mdipierro/web2py/devel branch as the default branch. This means that people will be able to type: bzr branch lp:web2py This is much easier to remember than: bzr branch lp:~mdipierro/web2py/ devel Instructions are available here https://help.launchpad.net/Code/QuickStart#Set your project's trunk branch. It should take you less than a minute to configure the change, but will make others' lives much simpler. Many thanks, Tim
