README randomly lists 1 out of 3 dependencies

[sourcejedi]

README lists only 1 of the three python dependencies listed in setup.py. ("Installation Guide" is better).

The instructions in README allow for "Install netaddr however you see fit". This is currently pointless, because when you install debops using pip, it will install passlib (and in theory argparse) how pip sees fit. I.e. from PyPI instead of OS packages.

It might actually be better to remove this from README, and replace it by mentioning the Installation Guide. E.g. "pip will install python dependencies automatically. If you prefer to use your OS packages, please see the Installation Guide for a list of dependencies".

I might prefer to use setup.py --requires as documented in setup.py --help. Sadly this simply prints a blank line (even when the deps are not installed). It looks like I want to use pip install . --no-deps
