Best regards, Neil Edde Vice President and Publisher Sybex, an Imprint of Wiley [email protected] 9 | P ag e Acknowledgments Although this book bears my name as author, many other people contributed to its creation. Without their help, this book wouldn’t exist, or at best would exist in a lesser form. Jeff Kellum was the acquisitions editor and so helped get the book started. Jennifer Leland, the development editor, and Liz Britten, the production editor, oversaw the book as it progressed through all its stages. Ralph Bonnell was the technical editor, who checked the text for technical errors and omissions—but any mistakes that remain are my own. Kim Wimpsett, the copy editor, helped keep the text grammatical and understandable. The proofreader, Jen Larsen, and technical proofreader, Don Corbet, checked the text for typos. I’d also like to thank Neil Salkind and others at Studio B, who helped connect me with Wiley to write this book. [email protected] 10 | P ag e
