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

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:

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.
