7. AGGREGATION WITH INDEPENDENT WORKS
      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.
