  • Section 4 - Author's instructions for using the GPL

    To display author's instructions for using the GPL:
        say "[bold type]How to Apply These Terms to Your New Programs[roman type]";
        say "[paragraph break]If you develop a new program, and you want it to be of the greatest
    possible use to the public, the best way to achieve this is to make it
    free software which everyone can redistribute and change under these terms.";
        say "[line break]To do so, attach the following notices to the program. It is safest
    to attach them to the start of each source file to most effectively
    state the exclusion of warranty; and each file should have at least
    the 'copyright' line and a pointer to where the full notice is found.";
        say "[fixed letter spacing][italic type]";
        say "[line break]<one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year> <name of author>";
        say "[paragraph break]This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.";
        say "[line break]This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
    GNU General Public License for more details.";
        say "[line break]You should have received a copy of the GNU General Public License
    along with this program. If not, see <http://www.gnu.org/licenses/>.";
        say "[roman type][variable letter spacing]";
        say "[line break]Also add information on how to contact you by electronic and paper mail.";
        say "[line break]You should also get your employer (if you work as a programmer) or school,
    if any, to sign a 'copyright disclaimer' for the program, if necessary.
    For more information on this, and how to apply and follow the GNU GPL, see
    <http://www.gnu.org/licenses/>.";
        say "[line break]The GNU General Public License does not permit incorporating your program
    into proprietary programs. If your program is a subroutine library, you
    may consider it more useful to permit linking proprietary applications with
    the library. If this is what you want to do, use the GNU Lesser General
    Public License instead of this License. But first, please read
    <http://www.gnu.org/philosophy/why-not-lgpl.html>."
