Combining documents
You may combine the Document with other documents released
under this License, under the terms defined in section 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
.
