+# This script is the frontend to be used with
+# the vsys system.
+# It allows to configure dummynet pipes and queues.
+# In detail it:
+# - get user input
+# - send command to the vsys input pipe
+# - wait a bit
+# - get the reply from the output vsys pipe
+# - show the output to the user
+# 
+# A simple usage is:
+# ./netconfig -p 9898 <dummynet configuration parameters>
+# mandatory fields are the port to be configured
+# and dummynet configuration parameters
