Or, if your .txt-files would only need a limited sets of functions and not too much code (we are not talking about real-time code here, do we?) you can easily make some kind of simple naive parser (e.g. line-by-line each argument separated by space, first argument function-name) for it without that much knowledge on how to write an optimized one.
