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: “Swing Hacks
by Joshua Marinacci and Chris Adamson. Copyright 2005 O’Reilly Media,

If you feel your use of code examples falls outside fair use or the permission
given above, feel free to contact us at permissions@oreilly.com.
