The small example code snippets listed in this book text and my code for the larger
example applications and libraries in the code ZIP file are licensed using the AGPL.7
Commercial waiver of some AGPL terms for people or organizations who pur-
chase this book:
If you purchase the print edition or purchase the PDF file8 of this book then I grant
you a partial commercial use waiver to the AGPL deploying your applications on a
single server: you can use my examples in applications on a single server without the
requirement of releasing the source code for your application under the AGPL (all
other AGPL license terms apply). If you need to run an application using my code on
multiple servers, then please purchase one copy of the book for each server.
I enjoy writing and purchasing copies of this book helps fund future writing projects.
