    <title>How to Apply These Terms to Your New Programs</title>

    <para>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.</para>

    <para>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 convey the exclusion of warranty; and each file should
    have at least the <quote>copyright</quote> line and a pointer to
    where the full notice is found.</para>

    <programlisting>
    &lt;one line to give the program's name and a brief idea of what it does.&gt;

    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of

    GNU General Public License for more details.

    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
    </programlisting>

    <para>Also add information on how to contact you by electronic and
    paper mail.</para>

    <para>If the program is interactive, make it output a short notice
    like this when it starts in an interactive mode:</para>

    <programlisting>
    Gnomovision version 69, Copyright (C) 19yy name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
    </programlisting>

    <para>The hypothetical commands `show w' and `show c' should show
    the appropriate parts of the General Public License.  Of course,
    the commands you use may be called something other than `show w'
    and `show c'; they could even be mouse-clicks or menu
    items&ndash;whatever suits your program.</para>

    <para>You should also get your employer (if you work as a
    programmer) or your school, if any, to sign a <quote>copyright
    disclaimer</quote> for the program, if necessary.  Here is a sample;
    alter the names:</para>

    <programlisting>
    Yoyodyne, Inc., hereby disclaims all copyright interest in the program
    `Gnomovision' (which makes passes at compilers) written by James Hacker.

    </programlisting>

    <para>This 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 Library General Public License
    instead of this License.</para>
