Acknowledgments

Thanks to my wife, Rebecca, for working with me to get this book completed. I really don’t know what I would have done without her help in researching and compiling some of the information that appears in this book. She also did a fine job of proofreading my rough draft and the final result.

David Clark deserves thanks for his technical edit of this book. He greatly added to the accuracy and depth of the material you see here. David also contributed a number of great URLs and interesting ideas. His attention to detail is especially appreciated in a book of this type.

Matt Wagner, my agent, deserves credit for helping me get the contract in the first place and taking care of all the details that most authors don’t really consider. I always appreciate his help. It’s good to know that someone wants to help.

Finally, I would like to thank Tom Cirtin, Leslie Light, Cheryl Hauser, Scott Benoit, and the rest of the editorial and production staff at Sybex for their assistance in bringing this book to print. It’s always nice to work with such a great group of professionals.
