You're welcome! As usual, each of us is free to write the code whichever way works best for the particular problem at hand. That's why the module documentation often avoids advocating here-is-the-one-best-way-to-do-it. I just like sticking all the option setup stuff in a single function because it's conceptually all the same and it makes the main() function or whatever read shorter. It's partly down to experience, what little of it I can claim.
