+You can also make a set of options mutually exclusive, i.e. only one option can be checked within the group at once.

 Note 1: nested `OPTION` tags are not supported.
 
 Note 2: If an included Preset has options, those options will not be shown to the user, unless ‘dummy’ option tags have been supplied, pre-defined, for each of the regions from the included Preset, like this:
