"""
This is a very small 'tox' plugin.
'toxfile.py' is a special name for auto-loading a plugin without defining package
metadata.
For full doc, see: https://tox.wiki/en/latest/plugins.html
Methods decorated below with `tox.plugin.impl` are hook implementations.
We only implement hooks which we need.
