+  Linking this library statically or dynamically with other modules is making

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

+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
