How to Contribute to This Book

As a copylefted work, this book is open to revision and expansion by any interested parties. The only "catch" is that credit must be given where credit is due.

If you wish to cite portions of this book in a work of your own, you must follow the same guidelines as for any other copyrighted work. Here is a sample for the CreativeCommons CC BY License:

If you wish to modify this book in any way, you should document the nature of those modifications in the "Credits" section along with your name, and ideally, information concerning how you may be contacted. Again, the CC BY License:

 You may do so in any reasonable manner, but not in any 
 way that suggests the licensor endorses you or your use.

Given the complexities and security issues surrounding the maintenance of files comprising this book, it is recommended that you submit any revisions or expansions to the original author (Tony R. Kuphaldt). You are, of course, welcome to modify this book directly by editing your own personal copy, but we would all stand to benefit from your contributions if your ideas were incorporated into the online "master copy" where all the world can see it.
