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, is called an "aggregate" if the +copyright resulting from the compilation is not used to limit the legal +rights of the compilation's users beyond what the individual works +permit. When the Document is included in an aggregate, this License does +not apply to the other works in the aggregate which 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 half of +the entire aggregate, the Document's Cover Texts may be placed on covers +that bracket the Document within the aggregate, or the electronic +equivalent of covers if the Document is in electronic form. Otherwise +they must appear on printed covers that bracket the whole +aggregate.
