 separate configuration language was deemed to be unpractical and
 would limit the possibilities.
 
+Usage:
+        funkensturm [flags]
+
+The flags are:
+
+        -sserver
+                        Listener address and port for the server. This has to be
+                        specified as: address:port, for instance 127.0.0.1:8053.
+                        This is also the default.
+        -rserver 
+                        Remote server address in address:port format. This can be
+                        repeated, for each rserver a resolver channel is created.
+                        The first begin `qr[0]`, the second `qr[1]`, etc.
+                        The default is: 127.0.0.1:53
+
+Debugging flags:
+
+        -verbose
+                        Print packets as they flow through Funkensturm.
+
+Predefined configurations are shown in `config_delay.go` and `config_sign.go`. The
+default `config.go` implements a transparant proxy.
