Also automatcially handles the issue of public vs private etc. Note this [1] recommends using zip files for speed, especially for larger repositories:

    pip install https://github.com/django/django/archive/master.zip

    pip install https://github.com/django/django/archive/stable/1.7.x.zip

I do that where I work because we have an internal git that is wide open, but packages from the outside world need to get whitelisted.

More controversially: With a few (<10) lines of code in your setup file, you can make an install-able module out of jupyter notebooks.

But now packages on PyPI can't depend on it.

How does this work for dependencies?

And what if some of the dependencies are incompatible with the versions already on your system?
