This book would not have seen the light of day without the help of my top-notch editors Andy Oram, Laurie Petrycki, John Posner, and Ellen Siever; the production staff, including Colleen Gorman, Emily Quill, and Ellen Troutman-Zaig; my brilliant reviewers Jeff Liggett, Jon Udell, Anne-Marie Vaduva, Andy Oram, Norm Walsh, and Jessica P. Hekman; my esteemed coworkers Sheryl Avruch, Cliff Dyer, Jason McIntosh, Lenny Muellner, Benn Salter, Mike Sierra, and Frank Willison; Stephen Spainhour for his help in writing the appendixes; and Chris Maden, for the enthusiasm and knowledge necessary to get this project started
