-The real legal meaning of the GNU General Public License (copyleft) will
-only be known if and when a judge rules on its validity and scope.
-There has never been a copyright infringement case involving the GPL to
-set any precedents.  Although legal actions have been brought against
-companies for violating the terms of the GPL, so far all have been
-settled out of court (in favor of the plaintiffs).  Please take any
-discussion regarding this issue to
-@uref{https://lists.gnu.org/mailman/listinfo/gnu-misc-discuss, the
-gnu-misc-discuss mailing list}, which was created to hold the
-extensive flame wars on the subject.

-The legal meaning of the GNU copyleft is less important than the spirit,
-which is that Emacs is a free software project and that work pertaining
-to Emacs should also be free software.  ``Free'' means that all users
-have the freedom to study, share, change and improve Emacs.  To make
-sure everyone has this freedom, pass along source code when you
-distribute any version of Emacs or a related program, and give the
-recipients the same freedom that you enjoyed.
