Acknowledgments

Many people have contributed significantly to this book. Elise Walter of New Riders, the editor, worked at all phases of our writing effort to ensure that this book was the best it could possibly be. Larry Paccone and Patrick Ramseier, the technical editors, made many insightful suggestions. Amy Lepore served as copy editor and Cheryl Lenser as indexer. And we cannot forget Jeff Riley of New Riders ‚ manager extraor-dinaire. Jeff 's humor and motivating comments kept us going as we wrote this book.

Jim Mellander and Russ Montello also helped by providing superb technical input when we asked them to.

Special thanks go to Dr.Terry Gudaitis who wrote Chapter 10 of this book despite her extremely busy schedule. We are confident that reading this chapter will show you why she enjoys the stellar reputation that she has.

Russ would also like to acknowledge his peers and coworkers, Tim Applby, Jennifer Braun, Dr.Terry Gudaitis, and Frank Schugar.
