"""
QDSpy module - to manage the configuration file
The 'Config' class manages the external configuration file 'QDSpy.ini'
using the configparser library. Use 'getParsedArg()' to parse arguments
for the command line version of QDSpy
Copyright (c) 2013-2024 Thomas Euler
All rights reserved.
2022-08-03 - Adapt to LINUX
2022-08-06 - Some reformatting
2024-06-12 - Reformatted (using Ruff)
- Fix for breaking change in `configparser`; now using
`ConfigParser` instead of `RawConfigParser`
- Small fixes for PEP violations
