 Programs should allow in this order: cli options, user configuration files
 passed by cli, environment variables, system configuration files and
 program defaults.
 There seems there's not a common easy way to achieve this in Python.
 sbws accepts cli and user configuration files in a complicated way.
 The program defaults are provided as a configuration file which might not
 be that convenient seems confuses where to find the defaults.
 Maybe an external library like https://github.com/bw2/ConfigArgParse
 (supported in Debian) or some other design can help to simplify this.
