Parsing textual parameter files is something that Perl is particularly good at doing.

- Present as short a possible example of the input and the output.
- Present the code that you have now - you get "big bonus points" for showing the Monks your attempt - no matter how imperfect that it may be.

For code, inclose it in <code>...your stuff here..verbatim..</code> tags.

It can be and sometimes is that your approach to the problem can be simplified. I don't know that without seeing "the problem". In other words, a demo of the desired result along with the code that you have now is more likely to result in a very good solution.
