It’s a poor craftsman who blames his tools. No blame attaches to the really great tools by which I have been assisted in the writing of this book. I am particularly grateful to the Unicomp Model M keyboard (http://pckeyboard.com), without which I could not have produced so large a book so painlessly. I was also aided by wonderful software, including TextMate (http://macromates.com) and AsciiDoc (http://www.methods.co.nz/asciidoc). BBEdit (http://www.barebones.com) helped with its
diff display. Screenshots were created with Snapz Pro X (http://www.ambrosiasw.com) and GraphicConverter (http://www.lemkesoft.com); diagrams were drawn with OmniGraffle (http://www.omnigroup.com).
The splendid O’Reilly production process converted my AsciiDoc text files into PDF while I worked, allowing me to proofread in simulated book format. Were it not for this, and the Early Release program that permitted me to provide my readers with periodic updates of the book as it grew, I would never have agreed to undertake this project in the first place. I would like particularly to thank Tools maven Abby Fox for her constant assistance.
I have taken advice from two tech reviewers, Dave Smith and David Rowland, and have been assisted materially and spiritually by many readers who submitted errata and encouragement. I was particularly fortunate in having Brian Jepson as editor; he provided enthusiasm for the O’Reilly tools and the electronic book formats, a watchful eye, and a trusting attitude; he also endured the role of communications pipeline when I needed to prod various parts of the O’Reilly machine. I have never written an O’Reilly book without the help of Nancy Kotary, and I didn’t intend to start now; her sharp eye has smoothed the bristles of my punctuation-laden style. For errors that remain, I take responsibility, of course.
