			=== Dependency Control ===

			[https://www.kennethreitz.org/essays/a-better-pip-workflow Great suggestion] for python dependency control:

			use two dependency files, one general, and one for current freeze version numbers
			node.js has a similar approach with its new lock files (good stuff i think)
			gentoo just fucking gets it right (nearly) every time, somehow
			---
			# requirements-to-freeze.txt (typical mostly-unconstrained Method #1) is used to specify your top-level dependencies, and any explicit versions you need to specify.
			# requirements.txt (fully-versioned Method #2) contains the output of $ pip freeze after $ pip install requirements-to-freeze.txt has been run.
			$ cd project-repo
			$ pip install -r requirements-to-freeze.txt --upgrade
			Installing collected packages: six, enum34, ipaddress, ...
			$ pip freeze > requirements.txt
			# The best of both worlds.
