MRE SystemSettings is a program to configure your system under AmigaOS; you are able to
  • start preference programs and edit config files,
  • view and change assigns and
  • view and change environment variables.
So it offers a fast and easy to use platform that ist not included in AmigaOS. And it is freeware!
