If my understanding is correct and you want to store rules, etc. in a config file, take a look at the Config::General module. It might be a useful solution.

Comment on Re: Suggestions for design of a config/rules file
I do understand the usability of the modules like Config::General etc. My question was more related to the format/contents of the file and if there is any reference for desinging such a format, somthing like creating your custom language.
