+circuitpusher utilizes floodlight rest APIs to create a bidirectional circuit,
+i.e., permanent flow entry, on all switches in route between two devices based
+on IP addresses with specified priority.
+
+Notes:
+ 1. The circuit pusher currently only creates circuit with two IP end points
+ 2. Prior to sending restAPI requests to the circuit pusher, the specified end
+ points must already been known to the controller (i.e., already have sent
+ packets on the network, easy way to assure this is to do a ping (to any
+ target) from the two hosts.
+ 3. The current supported command syntax format is:
+ a) circuitpusher.py --controller={IP}:{rest port} --type ip --src {IP} --dst {IP} --add --name {circuit-name}
+
+ adds a new circuit between src and dst devices Currently ip circuit is supported. ARP is automatically supported.
+
+ Currently a simple circuit record storage is provided in a text file circuits.json in the working directory.
+ The file is not protected and does not clean itself between controller restarts. The file is needed for correct operation
+ and the user should make sure deleting the file when floodlight controller is restarted.
+
+ b) circuitpusher.py --controller={IP}:{rest port} --delete --name {circuit-name}
+
+ deletes a created circuit (as recorded in circuits.json) using the previously given name
