Minor Description
From my test it looks like multiline values in INI files are not supported by commons-configuration2. I need to parse files like this one : https://github.com/glottolog/glottolog/blob/master/languoids/tree/abin1243/md.ini, and if I access configuration entry like "glottolog" on line 19 I am getting an empty string since the values are on the following lines.
ConfigParser in Python does support multiline values : https://docs.python.org/3/library/configparser.html (if they have one extra indentation compared to the line with the key).
