Specifications

You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this
License. Any other attempt to copy, modify, sublicense, or distribute the Document is void and will
automatically terminate your rights under this License. However, parties who have received copies, or rights,

compliance.
10. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License
from time to time. Such new versions will be similar in spirit to the present version but may differ in detail to
address new problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a
particular numbered version of this License "or any later version" applies to it, you have the option of
following the terms and conditions either of that specified version or of any later version that has been
published (not as a draft) by the Free Software Foundation. If the Document does not specify a version
number of this License, you may choose any version ever published (not as a draft) by the Free Software
Foundation.
ADDENDUM: How to use this License for your documents
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".
If you have Invariant Sections, Front−Cover Texts and Back−Cover Texts, replace the "with...Texts." line
with this: with the Invariant Sections being LIST THEIR TITLES, with the Front−Cover Texts being LIST,
and with the Back−Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some
other combination of the three, merge those two alternatives to suit the situation.
If your document contains nontrivial examples of program code, we recommend releasing these examples in
parallel under your choice of free software license, such as the GNU General Public License, to permit their
use in free software.
