Genuine thanks to the Sybex/Wiley team, particularly to Kenyon Brown for the opportunity to author this edition. To Kim Wimpsett and Archana Pragash, thank you for your guidance and patience, and answering all those questions. To Christine O'Connor, thank you for your support. Finally, to Chris Crayton, thank you for pointing out all the little things and providing a fresh perspective. It takes a team to create an excellent book, and the readers have these people to thank for the quality found in the pages that follow.
