Acknowledgments for the First version

Many thanks to everyone who helped out on this tutorial. Thanks to Larry Wall, Randal Schwartz, Tom Christiansen, and Sriram Srinivasan for their excellent tutorials on Perl. Some material in this tutorial is adapted from theirs; for that, we are very grateful.

Thanks also to all the reviewers of this tutorial, who include Randal Schwartz, Tom Christiansen, Graham Barr, Clinton Wong, and Erik Olson. Without their help, this tutorial wouldn't be nearly as helpful as it is.

We'd like to thank Linda Mui, our editor, and Val Quercia, who kept us on track, for all their support.
