Acknowledgments

I would like to thank my wife, Teresa. She has had so much patience

during the writing of this book. I would also like to thank the many

people who made this book possible, including the following: Kenyon

Brown at Wiley Publishing for giving me the opportunity to write this

book; Caroline Define, for working with me as the developmental

editor and making the entire project seamless; Christine O’Connor,

for helping with production editing and guiding me through the

process; Todd Montgomery, for serving as technical reviewer to

ensure I didn’t miss any details; and Judy Flynn, for her many edits

that helped make this book a polished product. Thank you to the

many other people I’ve never met who worked behind the scenes to

make this book a success.
