How these files differ from modopts.ini (and by extension,
ctrl/modopts.d/*.ini):

- The root section is always parsed, part of the returned object
- [sections] denote ARS that if matched (current user meets requirements)
  then those key/values are added as properties of the returned object
  possibly overriding previously defined properties (options), this allows
  different users (or clients/hosts, terminals) to get different option
  values much more easily
