% 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?)
|
|
|
|
|
2014-11-09 19:07:02 +00:00
|
|
|
% * 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.

\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
|
2014-03-15 15:06:33 +00:00
|
|
|
compliance with the GPL, for engineers, managers, and lawyers, as well as
|
2014-02-20 15:33:16 +00:00
|
|
|
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
|
2014-03-15 15:06:38 +00:00
|
|
|
and presentation supplements this printed curriculum. Simply reading this
|
|
|
|
material is \textbf{not an equivalent} for attending a course.
