Using This Book’s Code

The code in this book is designed to teach and I’m glad when it assists readers in that capacity. 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 the author for permission unless you’re reproducing a significant portion of the code. In other words: writing a program that uses several chunks of code from this book does not require permission but selling or distributing the code examples does require permission. Answering a question by quoting this book or its example code does not require permission but incorporating a significant amount of example code from this book into your product’s documentation does require written permission.
