Fawkes Runtime Exception to GPL 2.0 or later

Linking this library statically or dynamically with other modules is
making a combined work based on this library. Thus, the terms and
conditions of the GNU General Public License cover the whole
combination. As a special exception, the copyright holders of this
library give you permission to link this library with independent
modules to produce an executable, regardless of the license terms of
these independent modules, and to copy and distribute the resulting
executable under terms of your choice, provided that you also meet, for
each linked independent module, the terms and conditions of the license
of that module. An independent module is a module which is not derived
from or based on this library. If you modify this library, you may
extend this exception to your version of the library, but you are not
obligated to do so. If you do not wish to do so, delete this exception
statement from your version. Additionally if other files instantiate
templates or use macros or inline functions from this file, or you
compile this file and link it with other files to produce an executable,
this file 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.
