The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are
multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses,
the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections Entitled History in the various original documents, forming one section Entitled History ; likewise
combine any sections Entitled Acknowledgements , and any sections Entitled Dedications . You must delete all sections Entitled Endorsements.
17.6 COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in
the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of
the documents in all other respects.
You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the
extracted document, and follow this License in all other respects regarding verbatim copying of that document.
17.7 AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution
medium, is called an aggregate if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the
individual works permit. When the Document is included an aggregate, this License does not apply to the other works in the aggregate which are not
themselves derivative works of the Document.
If the Cover Text requirement of section 17.3 is applicable to these copies of the Document, then if the Document is less than one half of the entire
aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if
the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.
17.8 TRANSLATION
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 17.4. Replacing Invariant
Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in
addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and
any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and
disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will
prevail.
If a section in the Document is Entitled “Acknowledgements” , “Dedications” , or “History”, the requirement (section 17.4) to Preserve its Title (section
17.1) will typically require changing the actual title.
17.9 TERMINATION
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, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
17.10 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 © 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 non-trivial 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.
