that @mlinksva provided.

+% FIXME: We need an Introduction.  I think ideally it goes here, before Part
+%  I.  The introduction should cover initially:
+%
+%
+%     * Why we cover the topics in the order that we do, in particular, why
+%       we discuss all GPLv2 before mentioning  GPLv3 (i.e., explain why we
+%       take a diachronic approach to study of GPL).
+%
+%     * It should briefly discuss Free Culture / Software Freedom stuff.
+%       Maybe some early material currently living in gpl-lgpl.tex should move
+%       to the introduction, maybe not.  The goal is to prepare for the
+%       moment when we can merge in material about CC-BY-SA.
