Linking this library statically or dynamically with other modules is

As a special exception, the copyright holders of this library give you

permission to link this library with independent modules to produce an
28
executable, regardless of the license terms of these independent
29
modules, and to copy and distribute the resulting executable under terms
30
of your choice, provided that you also meet, for each linked independent
31
module, the terms and conditions of the license of that module.  An
32
independent module is a module which is not derived from or based on
33
this library.  If you modify this library, you may extend this exception
34
to your version of the library, but you are not obligated to do so.  If
35
you do not wish to do so, delete this exception statement from your
