License

The DUNE library and headers are licensed under version 2 of the GNU General Public License, 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 library 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.

This license clones the one of the libstc++ library. For further implications please see the license page of libstdc++. For the complete text of the GNU GPL see the COPYING file in this directory.
