This book represents the culmination of hard work from many different people to whom I owe my thanks. I’d like to begin by recognizing the book’s acquisitions editor, Mitzi Koontz, for helping to make this book a reality. I want to thank Jenny Davidson who served as the book’s project/copy editor and worked hard to help keep me straight and to ensure that everything came together like it was supposed to. Thanks also goes out to Keith Davenport, who served as the book’s technical editor and provided me with his invaluable insight and advice. Finally, I would like to thank everyone else at Thomson Course Technology PTR for their contributions and hard work.
