## 21.1 A Grab-Bag

Let's face it, even in a book as loosely structured as this one, there are things that don't quite fit. This chapter gave us a place to say a few things about files that we just didn't manage to cover anywhere else.

The chapter is short, and it's late, so I'm not even going to bother with the summary I might otherwise attempt in a situation like this. Just dive in.
