Huh? How can the user of a program then change the setting. I'm not
interested in making program where the user have to be a superuser and
know how to hand-edit config files. If one is building a GUI application
this application should also provide a gui to the settings so that the
user can configure it easily. Therefore the program need to write config
files too.

The program should report an error in the config file, but as others
have suggested this should be up to the developer how to deal with this.

Ah ok. Too complicated for non Ada users I think.
