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. This is a copyrighted work: it is not in the public
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
from the Design Science License:
The Work is copyright the Author. All rights to the Work are reserved
by the Author, except as specifically described below. This License
describes the terms and conditions under which the Author permits you
to copy, distribute and modify copies of the Work.
In addition, you may refer to the Work, talk about it, and (as
dictated by "fair use") quote from it, just as you would any
copyrighted material under copyright law.
Your right to operate, perform, read or otherwise interpret and/or
execute the Work is unrestricted; however, you do so at your own risk,
because the Work comes WITHOUT ANY WARRANTY -- see Section 7 ("NO
If you wish to modify this book in any way, you must 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 Design Science
Permission is granted to modify or sample from a copy of the Work,
producing a derivative work, and to distribute the derivative work
under the terms described in the section for distribution above,
provided that the following terms are met:
(a) The new, derivative work is published under the terms of this
(b) The derivative work is given a new name, so that its name or
title can not be confused with the Work, or with a version of
the Work, in any way.
(c) Appropriate authorship credit is given: for the differences
between the Work and the new derivative work, authorship is
attributed to you, while the material sampled or used from
the Work remains attributed to the original Author; appropriate
notice must be included with the new work indicating the nature
and the dates of any modifications of the Work made by you.
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.
All entries arranged in alphabetical order of surname. Major contributions
are listed by individual name with some detail on the nature of the
contribution(s), date, contact info, etc. Minor contributions (typo corrections,
etc.) are listed by name only for reasons of brevity. Please understand that
when I classify a contribution as "minor," it is in no way inferior to the
effort or value of a "major" contribution, just smaller in the sense of less
text changed. Any and all contributions are gratefully accepted. I am indebted
to all those who have given freely of their own knowledge, time, and resources
to make this a better book!
