    python-openstackclient development environment setup is complete.

    python-openstackclient development uses virtualenv to track and manage Python
    dependencies while in development and testing.

    To activate the python-openstackclient virtualenv for the extent of your current
    shell session you can run:

    $ source .venv/bin/activate

    Or, if you prefer, you can run commands in the virtualenv on a case by case
    basis by running:

    $ tools/with_venv.sh <your command>

    Also, make test will automatically use the virtualenv.
