1. Colophon

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Perl for Web Site Mangement is a proboscis monkey. The coastal rainforests and mangrove swamps of Borneo and the forests of the lower Kinabatangan River have the largest concentration of this species (Nasalis larvatus). Their fur is brick-red, and they have long tails and large bellies. The most obvious feature of Proboscis monkeys is the male's extremely long nose, which is shaped like a cucumber. The monkeys travel in groups of about five to fifteen. A group is usually made up of a dominant adult male with a harem of up to ten females as well as juveniles. They are vegetarians, eating primarily leaves, along with fruit, seeds, and flowers. Unusually among apes, they are very skilled swimmers and divers in the rivers that make up a large part of their habitat. The proboscis monkey's Malaysian name is Monyet Belanda, translated as "Dutchman Monkey." During the European colonial period, the Malaysians apparently thought the monkeys' red hair, pot bellies, and big noses resembled the European traders and colonialists.

This unique monkey is threatened with extinction through hunting and loss of habitat. The rainforests and swamps where they live are under severe threat from logging and land clearing. Attempts to keep this monkey in zoos have not been successful; the shy species does not survive. The only way to observe the proboscis monkey is in the rainforest, its natural habitat in the wild. Colleen Gorman was the production editor, and Audrey Doyle was the copyeditor for Perl for Web Site Mangement. Sada Preisch and Leanne Soylemez provided quality control. Judy Hoer wrote the index.

Hanna Dyer designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.

David Futato designed the interior layout. Neil Walls converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike Sierra. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read using Macromedia Free-Hand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing. This colophon was written by Colleen Gorman.

Whenever possible, our books use a durable and flexible lay-flat binding. If the page count exceeds this binding's limit, perfect binding is used.
