O'Reilly Releases "Mac OS X for Unix Geeks:"

From O'Reilly, "If you're one of the many Unix developers drawn to Mac OS X for its BSD core, you'll find yourself in surprisingly unfamiliar territory. Even if you're an experienced Mac user, Mac OS X is unlike earlier Macs, and it's radically different from the Unix you've used before, too."

"Enter "Mac OS X for Unix Geeks" (O'Reilly, US $24.95) by Brian Jepson and Ernest E. Rothman, two Unix geeks who found themselves in the same place as many others. Chapter 3, "Directory Services," is available free online. For more information about the book, including Table of Contents, index, author bios, and samples, see this web page."
