P.2. Using Code Examples

This book is here to help you get your job done. In general, you may use the code in this book in your programs and documentation. You do not need to contact us for permission unless you’re reproducing a significant portion of the code. For example, writing a program that uses several chunks of code from this book does not require permission. Selling or distributing a CD-ROM of examples from O’Reilly books does require permission. Answering a question by citing this book and quoting example code does not require permission. Incorporating a significant amount of example code from this book into your product’s documentation does require permission.

We appreciate, but do not require, attribution. An attribution usually includes the title, author, publisher, and ISBN. For example: “Scaling CouchDB by Bradley Holt (O’Reilly). Copyright 2011 Bradley Holt, 978-1-449-30343-3.”

P.5. Acknowledgments

I’d first like to thank Damien Katz, creator of CouchDB, and all of CouchDB’s contributors. I’d also like to thank all of the contributors to the other open source software tools referenced in this book. This includes contributors to the Apache HTTP Server, BigCouch, CouchDB Lounge, Pillow, and Tsung. Knut Ola Hellan (creator of Pillow) and Martin Brown (from Couchbase) both provided valuable feedback which helped to make this book better. Mike Loukides, this book’s editor, and the rest of the team at O’Reilly Media were very responsive and helpful.
