% I'm somewhat convinced that this book would be better formatted using
% the memoir class :
% http://www.ctan.org/pkg/memoir
% http://mirror.unl.edu/ctan/macros/latex/contrib/memoir/memman.pdf
% For the moment, I've thrown in fancychap because I don't have time to
% research memoir.
% FIXME: Some overall formatting hacks that would really help:
% * I have started using \hyperref[LABEL]{text} extensively, which seems
% to work great in the PDF and HTML versions, but in the Postscript
% version, the link lost entirely. I think we need an additional command
% to replace \hyperref which takes an optional third argument that will
% insert additional text only when generating print versions, such as:
% \newhyperref[GPLv2s3]{the requirements for binary distribution under
% GPLv2}{(see section~\ref*{GPLv2s3} for more information)}
% This is a careful balance, because it'd be all too easy to over-pepper
% the printed version with back/forward references, but there are
% probably times when this is useful.
% * Similar issue: \href{} is well known not to carry the URLs in the print
% versions. Adding a footnote with the URL for the print version is
% probably right. (or maybe a References page?)
% * The text is extremely inconsistent regarding formatting of code and
% commands. The following varied different methods have been used:
% + the \verb%..% inline form
% + verbatim environment (i.e., \begin{verbatim}
% + {\tt }
% + \texttt{}
% + the lstlisting environment (i.e., \begin{lstlisting}
% These should be made consistent, using only two forms: one for line and
% one for a long quoted section.
% FIXME: s/GPL enforcers/COGEOs/g
% (the term coined later but not used throughout) This can't be done
% by rote, since it may not be appropriate everywhere and shouldn't be
% used *before* it's coined in the early portions of
% compliance-guide.tex (and it's probably difficult to coin it earlier
% anyway). BTW, I admit COGEOs isn't the best acronym, but I started
% with ``Community Enforcement Organizations'', which makes CEO, which
% is worse. :) My other opting was COEO, which seemed too close to
% CEO. Suggestions welcome.

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 equivalent} to attending a course.
