CubicWeb dependencies and standard set of cubes have been fetched and
update to the latest stable version.

You should ensure your PYTHONPATH contains `%(basedir)s`.
You might want to read the environment configuration section of the documentation
at http://docs.cubicweb.org/admin/setup.html#environment-configuration

You can find more cubes at http://www.cubicweb.org.
Clone them from `%(baseurl)scubes/` into the `%(basedir)s%(sep)scubes%(sep)s` directory.

To get started you may read http://docs.cubicweb.org/tutorials/base/index.html.
