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."
