-                    '5. You are not required to accept this License, since you have '

+                   'have the freedom to distribute copies of free software (and charge for '
+                   'them if you wish), that you receive source code or can get it if you '
+                   'want it, that you can change the software or use pieces of it in new '
+                   'free programs, and that you know you can do these things.</p>'
+                   '<p>To protect your rights, we need to prevent others from denying you '
+                   'these rights or asking you to surrender the rights.  Therefore, you have '
