+NetSED is small and handful utility designed to alter the contents of
+packets forwarded thru your network in real time. It is really useful
+for network hackers in following applications:
+
+  * black-box protocol auditing - whenever there are two or more
+    propertiary boxes communicating over undocumented protocol (by enforcing 
+    changes in ongoing transmissions, you will be able to test if tested 
+    application is secure),
+
+  * fuzz-alike experiments, integrity tests - whenever you want to test 
+    stability of the application and see how it ensures data integrity,
+
+  * other common applications - fooling other people, content filtering,
+    etc etc - choose whatever you want to.
