Ah, you see, now you've gone and done it. You've either downloaded (or you're showing interest in downloading) a framework. Some would have you think that you're adding unnecessary complication to your development life, or that you're about to box yourself in with a set of rules.
That's just silly hogwash.
Welcome to Model-Glue. It's tidy, small, and simple to learn. Its rules don't exist to confine you. Instead, they simply ask that you put certain kinds of code in certain places, and for very good reasons. By organizing your code a bit, you'll find that you start reusing more code, writing less bugs, and overall, having a lot less headaches and lot more time for things like walks in the park.
