Check your [w]req(uirements).in
For use in conjunction with pip-tools.
Tries to find packages that are no longer top-level requirements.
Install using pip:
$ pip install git+https://github.com/davidszotten/wrecking-check@master
Point at your requirements.in and top level directory:
$ wrecking-check requirements.in src/ foo bar
Some libraries are required but not directly imported by your code, e.g. pytest plugins, web servers and django database drivers.
These are heuristics. Use carefully and at your own risk.
