This PS adds tooling and automation to automatically generate
Berth's documentation into feature-rich HTML pages that can
be hosted.
To run the documentation job, simply execute:
tox -e docs
Future docs should be written using the style described at
http://www.sphinx-doc.org/en/stable/markup/code.html and
located in berth/docs/source
This PS also adds basic building blocks required by most any
Python project:
* test-requirements.txt
* requirements.txt
* setup.cfg
* setup.py
* added more filters to .gitignore
