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 featured on the cover of sed & awk, Second Edition, is a slender loris. Lorises are nocturnal, tree-dwelling, tailless primates with thick, soft fur and large, round eyes. They are found in Southern India and Ceylon, where they live in trees, rarely descending to the ground. Lorises have been observed urinating on their hands and feet--it is thought that they do this to improve their grip while climbing and to leave a scent trail.

A small animal, the slender loris is generally between 7 and 10 inches in size and weighs 12 ounces or less. It subsists on a diet of fruit, leaves, and shoots and small animals that it captures by hand.

Edie Freedman designed the cover of this book, using a 19th-century engraving from the Dover Pictorial Archive. The cover layout was produced with Quark XPress 3.3 using the ITC Garamond font.

The inside layout was designed by Nancy Priest and Mary Jane Walsh. Text was prepared in SGML using the DocBook 2.1 DTD. The print version of this book was created by translating the SGML source into a set of gtroff macros using a filter developed at ORA by Norman Walsh. Steve Talbott designed and wrote the underlying macro set on the basis of the GNU troff -gs macros; Lenny Muellner adapted them to SGML and implemented the book design. The GNU groff text formatter version 1.09 was used to generate PostScript output. The text and heading fonts are ITC Garamond Light and Garamond Book; the constant-width font used in this book is Letter Gothic. The illustrations that appear in the book were created in Macromedia Freehand 5.0 by Chris Reilley.

The online edition of this book was created by the Safari production group (John Chodacki, Becki Maisch, and Madeleine Newell) using a set of Frame-to-XML conversion and cleanup tools written and maintained by Erik Ray, Benn Salter, John Chodacki, and Jeff Liggett.
