If   there is no section Entitled ``History'' in the Document, create one   stating the title, year, authors, and publisher of the Document as   given on its Title Page, then add an item describing the Modified   Version as stated in the previous sentence.\item Preserve the network location, if any, given in the Document for   public access to a Transparent copy of the Document, and likewise   the network locations given in the Document for previous versions   it was based on.  These may be placed in the ``History'' section.   You may omit a network location for a work that was published at   least four years before the Document itself, or if the original   publisher of the version it refers to gives permission.\item For any section Entitled ``Acknowledgements'' or ``Dedications'',   Preserve the Title of the section, and preserve in the section all   the substance and tone of each of the contributor acknowledgements   and/or dedications given therein.\item Preserve all the Invariant Sections of the Document,   unaltered in their text and in their titles.

To do this, add their titles to thelist of Invariant Sections in the Modified Version's license notice.These titles must be distinct from any other section titles.You may add a section Entitled ``Endorsements'', provided it containsnothing but endorsements of your Modified Version by variousparties--for example, statements of peer review or that the text hasbeen approved by an organization as the authoritative definition of astandard.You may add a passage of up to five words as a Front-Cover Text, and apassage of up to 25 words as a Back-Cover Text, to the end of the listof Cover Texts in the Modified Version.  Only one passage ofFront-Cover Text and one of Back-Cover Text may be added by (orthrough arrangements made by) any one entity.  If the Document alreadyincludes a cover text for the same cover, previously added by you orby arrangement made by the same entity you are acting on behalf of,you may not add another; but you may replace the old one, on explicitpermission from the previous publisher that added the old one.The author(s) and publisher(s) of the Document do not by this Licensegive permission to use their names for publicity for or to assert orimply endorsement of any Modified Version.\section{COMBINING DOCUMENTS}\label{combining}You may combine the Document with other documents released under thisLicense, under the terms defined in section~\ref{modifications}above for modifiedversions, provided that you include in the combination all of theInvariant Sections of all of the original documents, unmodified, andlist them all as Invariant Sections of your combined work in itslicense notice, and that you preserve all their Warranty Disclaimers.The combined work need only contain one copy of this License, andmultiple identical Invariant Sections may be replaced with a singlecopy.  If there are multiple Invariant Sections with the same name butdifferent contents, make the title of each such section unique byadding at the end of it, in parentheses, the name of the originalauthor or publisher of that section if known, or else a unique number.Make the same adjustment to the section titles in the list ofInvariant 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 sectionsEntitled ``Endorsements''.\section{COLLECTIONS OF DOCUMENTS}\label{collections}You may make a collection consisting of the Document and other documentsreleased under this License, and replace the individual copies of thisLicense in the various documents with a single copy that is included inthe collection, provided that you follow the rules of this License forverbatim copying of each of the documents in all other respects.You may extract a single document from such a collection, and distributeit individually under this License, provided you insert a copy of thisLicense into the extracted document, and follow this License in allother respects regarding verbatim copying of that document.\section{AGGREGATION WITH INDEPENDENT WORKS}\label{aggregation}A compilation of the Document or its derivatives with other separateand independent documents or works, in or on a volume of a storage ordistribution medium, is called an ``aggregate'' if the copyrightresulting from the compilation is not used to limit the legal rightsof the compilation's users beyond what the individual works permit.When the Document is included in an aggregate, this License does notapply to the other works in the aggregate which are not themselvesderivative works of the Document.If the Cover Text requirement of section~\ref{copying} is applicable tothese copies of the Document, then if the Document is less than one halfof the entire aggregate, the Document's Cover Texts may be placed oncovers that bracket the Document within the aggregate, or theelectronic equivalent of covers if the Document is in electronic form.Otherwise they must appear on printed covers that bracket the wholeaggregate.\section{TRANSLATION}\label{translation}Translation is considered a kind of modification, so you maydistribute translations of the Document under the terms ofsection~\ref{modifications}.Replacing Invariant Sections with translations requires specialpermission from their copyright holders, but you may includetranslations of some or all Invariant Sections in addition to theoriginal versions of these Invariant Sections.  You may include atranslation of this License, and all the license notices in theDocument, and any Warranty Disclaimers, provided that you also includethe original English version of this License and the original versionsof those notices and disclaimers.  In case of a disagreement betweenthe translation and the original version of this License or a noticeor disclaimer, the original version will prevail.If a section in the Document is Entitled ``Acknowledgements'',``Dedications'', or ``History'', the requirement(section~\ref{modifications}) to Preserveits Title (section~\ref{applicability}) will typically requirechanging the actual title.\section{TERMINATION}\label{termination}You may not copy, modify, sublicense, or distribute the Document exceptas expressly provided for under this License.  Any other attempt tocopy, modify, sublicense or distribute the Document is void, and willautomatically terminate your rights under this License.
