ACKNOWLEDGMENTS

M

any technical books need the expertise of more than one person, and this one is no
exception. Thanks to John Watson for providing some last-minute materials to help
me finish before the very last deadline!
Thanks also go out to the copy editors at International Typesetting and
Composition for filling in the gaps in my college English courses, Carly Stapleton
and Tim Green for (trying to) keep me on schedule, and Gavin Powell, who gave me
good advice when the theoretical met the practical.

Many of my professional colleagues at Lands’ End were a source of both
inspiration and guidance, especially Brook Swenson, Karen Shelton, and Dan
Schwickrath. In this case, the whole is truly greater than the sum of its parts.
If you have any questions or comments about any part of this book, please do not
hesitate to contact me at
