Pip-Tools

A set of tools to keep your pinned Python dependencies fresh.

https://github.com/jazzband/pip-tools

You care about your application's direct dependencies
You want to pin versions of all depencies for reproducible development
- (setup.py vs requirements.txt: https://packaging.python.org/requirements/)
You want to keep depencies up-to-date
