+This book is here to help you get your job done. In general, if example code is
+offered with this book, you may use it 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 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:
