+	bool "tcping"
+	help
+	  tcping does a TCP connect to the given ip/port
+	  combination. The user can specify a timeout in seconds. This
+	  is useful in shell scripts running in firewalled
+	  environments. Often SYNs are just being dropped by
+	  firewalls, thus connection establishment will be retried
+	  several times (for minutes) until a TCP timeout is
+	  reached. With tcping it is possible to check first if the
+	  desired port is reachable and then start connection
+	  establishment.
