12. 授权附录：如何使用本授权用于你的文件

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled “GNU Free Documentation License”.

如果你有恒常章节、前封面文字和后封面文字，请将with… Texts这一行以这些文本取代：

with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.

如果你有不具封面文字的恒常章节，或一些其它这三者的组合，将可选择的二项合并以符合实际情形。

如果你的文件中包含有并非微不足道的程序码范例，我们建议这些范例平行地在你的自由软件授权选择下，比如以 GNU General Public License 的自由软件授权来发布，从而允许它们作为自由软件而使用。
