    As a special exception, you may use the dune-grid-glue source files as part of a
    software library or application without restriction.  Specifically, if other
    files instantiate templates or use macros or inline functions from one or
    more of the dune-grid-glue source files, or you compile one or more of the dune-grid-glue
    source files and link them with other files to produce an executable, this
    does not by itself cause the resulting executable to be covered by the GNU
    General Public License.  This exception does not however invalidate any
    other reasons why the executable file might be covered by the GNU General
    Public License.

  This license is intended to be similar to the GNU Lesser General Public
  License, Version 2, which by itself isn't suitable for a template library. You
