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."
