For the GNU software licenses, such as the GNU GPL, we have a <a href="/licenses/gpl-howto.html">separate page</a>.</p> <dl> <dt><a href="/licenses/fdl-howto-opt.html">How does one use the optional features of the FDL?</a></dt> <dd> We have a <a href="/licenses/fdl-howto-opt.html">separate page</a> that discusses how to use the optional features of the FDL.</dd> <dt>Where must one put the license notification?</dt> <dd> It is sufficient to put the full license notice in the “main” file of your document. For example, with the <cite>Emacs Lisp Reference Manual</cite>, we have many files included by <code>elisp.texi</code>. We keep the full notification in <code>elisp.texi</code>, and in the other files we simply write:<pre><pre class="emph-box"> @c -*-texinfo-*- @c This is part of the GNU Emacs Lisp Reference Manual. @c Copyright (C) 1990, 1991, 1992, 1993, 1994, 1999 @c Free Software Foundation, Inc. @c See the file elisp.texi for copying conditions. </pre></dd> <dt>What do I do with scripts that are needed to render my document properly?</dt> <dd> We recommend you release these scripts under the GNU FDL as well. Of course, if these scripts are generally useful for other tasks, it is a good idea to release them separately under the GNU GPL.</dd> <dt>Is it required for the document to have invariant sections?</dt> <dd> No. It is perfectly acceptable for a document to have no invariant sections.</dd> <dt>Should I try to make sure the document has some invariant sections?</dt> <dd> Not particularly. If a section's contents ought to be invariant, make it invariant.</dd> <dt>Should I try to avoid invariant sections?</dt> <dd> Not particularly. If a section's contents ought to be invariant, make it invariant.</dd> <dt>When should a section be invariant?</dt> <dd> First of all, keep in mind that a section that treats technical material <em>cannot</em> be invariant. Only a secondary section can be invariant, and a technical section is not a secondary section. <p> If the section is text that you're not allowed to modify, such as a copy of the GNU GPL, then it <em>must</em> be invariant. You can't give permission to modify it if you don't have permission to modify it.</p> <p> (One consequence is that you <em>cannot use</em> preexisting text which covers technical material if you don't have permission to allow modification of that text.)</p> <p> When a section discusses the philosophy of free software, it is a good idea to make that section invariant. For instance, when we put the GNU Manifesto in a manual, or when we include a section explaining why free documentation is important, we make that section invariant.</p></dd> </dl> </div> </div><!-- for id="content", starts in the include above --> <!--#include virtual="/server/footer.html" --> <divid="footer">id="footer" role="contentinfo"> <div class="unprintable"> <p>Please send general FSF & GNU inquiries to <a href="mailto:gnu@gnu.org"><gnu@gnu.org></a>.
