so we need some options to control what will be updated:
- executables
- libraries (lib*.so)
- regular files

we also need options to control what will be updated:
- only the file content
- permissions

and we need options to specify where they will be updated (which jails)

I think for a utility like this is would be nice if it could be done
without config file. If you want to run it regularly you can always
store the options in a cron script.
