COPYING

+The DUNE library and headers are licensed under version 2 of the GNU
+General Public License (see below), with a special exception for
+linking and compiling against DUNE, the so-called "runtime exception."
+The license is intended to be similiar to the GNU Lesser General
+Public License, which by itself isn't suitable for a template library.
+
+The exact wording of the exception reads as follows:
+
+   As a special exception, you may use the DUNE 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 source files, or you
+   compile one or more of the DUNE 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.
