Public Licenses and copyleft (as applied to software).

The primary item of interest is an omnibus book on copyleft that is built

from the comprehensive-GPL-guide.tex file.

You can also [download a prebuilt PDF file](http://ebb.org/bkuhn/articles/copyleft-book.pdf).

\chapter{Preface}

This tutorial is the culmination of nearly a decade of studying and writing

about software freedom licensing and the GPL\@.  Each part of this tutorial

is a course unto itself, educating the reader on a myriad of topics from the

deep details of the GPLv2 and GPLv3, common business models in the copyleft

licensing area (both the friendly and unfriendly kind), best practices for

compliance with the GPL, for engineers, managers, and lawyers, as well as

real-world case studies of GPL enforcement matters.

It is unlikely that all the information herein is necessary to learn all at

once, and therefore this tutorial likely serves best as a reference book.

The material herein has been used as the basis for numerous live tutorials

and discussion groups since 2002, and the materials have been periodically

updated.   They likely stand on their own as excellent reference material.

However, if you are reading these course materials without attending a live

tutorial session, please note that this material is merely a summary of the

highlights of the various CLE and other tutorial courses based on this

material.  Please be aware that during the actual courses, class discussion

and presentation supplements this printed curriculum.  Simply reading this

material is \textbf{not an equivalent} for attending a course.
