This book would not be possible without the encouragement of my friends and family. For the long hours and late nights of researching, writing, and editing that my family so graciously allotted me I will always be grateful.
I also owe a great deal to the technical reviewers of this book, Tom and Adriaan. Their feedback was always superb. All of the editors who worked on this book, especially Louise and Christine, were a tremendous help in moving this project along and responding to my queries.
