"""settings -- application settings, knobs and configuration

How to use! As a developer:

- Keep It Simple, Silly! A sysop will have to read and use it.

- Use simple, flat variables - scalars like integers or strings; avoid
  deeply nested dicts or arrays.

- Make conversion between an environment variable and a Python
  datatype simple and obvious:

    - ISO8601 for dates and times

    - "0"/"1" for bool False/True

    - comma-separated values for arrays, like: IPS=127./8,192.168./16

    - KISS

- Look at the current examples, try to follow the conventions!

As a system administrator / when preparing for deployment:

- Read this file!

- Everything else is in environment variables:

    - LOGLEVEL can be adjusted between:
      DEBUG, INFO, WARNING, ERROR, FATAL;

    - HOST and PORT are for the builtin dev server, and will be of
      little use, since you must use a real application server like
      uWSGI;

- Talk to the developers!
