 Barbican development environment setup is complete.

 Barbican development uses virtualenv to track and manage Python dependencies
 while in development and testing.

 To activate the Barbican 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.
