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."
