There are many people I would like to thank for the opportunity and help they gave before, during, and after this book was being written: Neil Salkind, for helping me navigate the world of publishing and for his support while I was writing. Robyn Thomas for her patience. Jay Blanchard for stepping in when needed and providing excellent technical reviews. Rebecca Gulick for helping to move things along. Michael Nolan for working out the details. All my customers, for understanding how busy I’ve been. And, of course, Peachpit for giving me the opportunity to write for you.
