Acknowledgments
F
irst, I must thank Tom Cirtin, who originally offered me the book on the basis of a brief
conversation at the beginning of the year. I also need to thank Jennifer Campbell, who
took over and managed the project after the initial stages. It’s been a long process with occa-
sional difficulties, but the people at Sybex were wonderful throughout the course of this
project.
I also need to thank Gene Redding, who copy edited the book for me—after almost five
years of writing, I’m still not as good as I could be. For the technical input, thanks go to
Charles Hornberger for highlighting missed opportunities and less-than-perfect examples.
Big thanks also have to go to all the people who do the work behind the scenes and pro-
duce the modules, extensions, and examples that make up this book. This includes—but in
no way is limited to—James Clarke, the folks at Late Night Software, Apple Computer, Inc.,
Scriptics, Larry Wall and the Perl team, Guido van Rossum, Fredrik Lundh, and the rest of
the Python and PyXML teams and the folks who work on PHP, Ruby, and Rebol.
There’s also a very special thanks to the people out there who helped me deal with the events
of September 11, 2001, which occurred during the writing of this book. My heart goes out to
anybody whose family was touched by the tragedies. Whilst neither I nor any of my family or
friends were involved in the events on that day, many of the people I know and work with were.
In particular, thanks and best wishes to Wendy Rinaldi, Rikke Jørgensen, and Aharon Robbins.
The penultimate thanks go to Neil Salkind and Vicki Harding, my agents, and to the rest
of the team at StudioB for keeping all my contracts, negotiations, and checks in order.
Finally, the biggest thanks should go to my wife. I would be lost without her, and all too
often she has to listen to my complaints and frustrations without any thanks or appreciation.
