title: Specific GIT app as PIP package install requirement
body: <p>I have this app <a href="https://github.com/staticdev/django-crud-utils" rel="noreferrer">https://github.com/staticdev/django-crud-utils</a> that need to have django-sorting installed to work. But it can't be the original django-sorting, but a fork I made: <a href="https://github.com/staticdev/django-sorting" rel="noreferrer">https://github.com/staticdev/django-sorting</a></p>
  
  <p>How do I put it in the setup.py file for packaging?</p>
  
  <p>Tks.</p>
