I want to thank everyone who was involved in creating my book. Without all the input from the people at Sybex, there would have been just my own thoughts and ideas, but certainly not a book. Thanks to Acquisitions Editor Maureen Adams; Technical Editors Patrick Bass and Arthur Pfund; Copy Editor Suzanne Goraj; Compositor Craig Woods of Happenstance Type-O-Rama; and Indexer Ted Laux.

I want to thank my pal Lloyd Wittebol, who supplied the test switches and regular advice. And Mae Lum, my Production Editor, and Heather O’Connor, my Developmental Editor. Without the tireless efforts and advice of these two ladies, this book would have been a poor shadow of itself. I look forward to working with you both again.

Finally, to my daughter Stephanie, who proofread, advised, cajoled, and encouraged me through the whole project, I offer my special thanks.
