add another; but you may replace the old one, on explicit permission from the previous publisher that
added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their
names for publicity for or to assert or imply endorsement of any Modified Version.
5. COMBINING DOCUMENTS
You may combine the Document with other documents released under this License, under the terms
defined in section 4 above for modified versions, provided that you include in the combination all of
the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant
Sections of your combined work in its license notice, and that you preserve all their Warranty
Disclaimers.
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".
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.
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 in 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 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.
