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.
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."
