First off, we’d like to thank our editor, Julie Steele, for helping us through the entire process of publishing our first book. We’d also like to thank Melanie Yarbrough and Genevieve d’Entremont for their remarkably thorough work in cleaning the book up for publication. We’d also like to thank the other people at O’Reilly who’ve helped to improve the book, but whose work was done in the background.

In addition to the kind folks at O’Reilly, we’d like to thank our technical reviewers: Mike Dewar, Max Shron, Matt Canning, Paul Dix, and Maxim Khesin. Their comments improved the book greatly and as the saying goes, the errors that remain are entirely our own responsibility.
