I want to use pip to install from the dev branch. But it fails because setup.py is not found in the repository root.

The following syntax is used to install straight from git repository:

sudo pip install git+git://github.com/daviddrysdale/python-phonenumbers.git@dev

Is it possible to move setup.py to the repository root to fix this? Alternatively, is it possible to run dev branch without maintaining a git clone of the repository on the target system?
