> Does PEP 440 cover this any better for you?
I actually think the example in PEP 440 are part of what caused my confusion,
because all of them are also for *pip*:
```
pip @ file:///localbuilds/pip-1.3.1.zip
pip @ file:///localbuilds/pip-1.3.1-py33-none-any.whl
pip @
https://github.com/pypa/pip
PEP 508 allows for pointing to required packages using URL's. This is the
except:
A minimal URL based lookup::
pip @
https://github.com/pypa/pip/archive/1.3.1.zip#sha1=da9234ee9982d4bbb3c72346a6de940a148ea686
However, there is very little documentation, blog posts, etc on how to us
