Thanks finally to the great people at O'Reilly who encouraged us to write it (Frank Willison and Sheryl Avruch), agreed to edit it (Frank), helped design it (Alicia Cech, who worked on the interior design, and Edie Freeman, who designed the cover), proofed and produced it (Chris Maden, Madeline Newell, and David Futato), and indexed it (Ellen Troutman).
