5. COMBINING DOCUMENTS

You may combine the Document with other documents released under this License, under the terms defined in sect1 4 above for modified versions, provided that you include in the combination all of the Invariant Sect1s of all of the original documents, unmodified, and list them all as Invariant Sect1s of your combined work in its license notice.

The combined work need only contain one copy of this License, and multiple identical Invariant Sect1s may be replaced with a single copy. If there are multiple Invariant Sect1s with the same name but different contents, make the title of each such sect1 unique by adding at the end of it, in parentheses, the name of the original author or publisher of that sect1 if known, or else a unique number. Make the same adjustment to the sect1 titles in the list of Invariant Sect1s in the license notice of the combined work.

In the combination, you must combine any sect1s entitled "History" in the various original documents, forming one sect1 entitled "History"; likewise combine any sect1s entitled "Acknowledgements", and any sect1s entitled "Dedications". You must delete all sect1s entitled "Endorsements."
