A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of a + storage or distribution medium, does not as a whole count as a Modified + Version of the Document, provided no compilation copyright is claimed for + the compilation. Such a compilation is called an "aggregate", and this + License does not apply to the other self-contained works thus compiled + with the Document, on account of their being thus compiled, if they are + not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one quarter of + the entire aggregate, the Document's Cover Texts may be placed on covers + that surround only the Document within the aggregate. Otherwise they must + appear on covers around the whole aggregate.
