"""
This class reads the configuration of an external music storage.
All sections and options can be accessed by their names: ``ExternConfig(...).section.option``.
If values get changed, they will not be stored!

Example:

    .. code-block:: ini

        [meta]
        version = 1

    .. code-block:: python

        cfg = ExternConfig("test.ini")
        print(cfg.meta.version)
