title: How does a django app start it's virtualenv?
body: <p>I'm trying to understand how virtual environment gets invoked. The website I have been tasked to manage has a .venv directory. When I ssh into the site to work on it I understand I need to invoke it with source .venv/bin/activate. My question is: how does the web application invoke the virtual environment? How do I know it is using the .venv, not the global python?</p>
  
  <p>More detail: It's a Drupal website with Django kind of glommed onto it. Apache it the main server. I believe the Django is served by gunicorn. The designer left town
