Simple ways to package code for sharing and reuse

Inevitably, there will come a time when you want to be able to reuse some functions or classes and not have to type (or—horror—copy and paste) them in every time. Having just one reliable version of things in one place makes it easy to manage and keep on top of mistakes and changes in code. So, in this recipe, we'll look at two simple ways of wrapping code up to reuse it. We'll touch on the very basics of package creation, though the packages we will make will be quite bare-bones and will need quite some fleshing out—especially with documentation and tests—before you consider releasing them. The packages you make in this way, though, will help you out as you develop your code.
