Creating our own processor can be a satisfying experience—we have total control over what elements should be included, and can add or remove elements at any time. Throughout the course of this book, we've explored a number of elements that make up what might be a typical processor; in this chapter, we pulled together all of these elements to create our final article. Let's take a moment to review what we have learnt.

We began with a look at some of the key elements of our processor, which we've already used previously, but have not really understood in detail how it all fits together. With this in mind, we moved on to examine some of the issues with our processor, before working out ways of correcting those issues and altering our code.

With our updated processor in place, we then took a look at ways of optimizing our output by altering existing functionality, or including new options that may or may not make up a baseline processor or one customized for a specific project. We then...
