 ======
 
 UDP buffer size (RX, TX) and dropped packages statistics program, written by PZolee (pzoleex @ freemail.hu), 2012
 https://github.com/pzolee/udpstat
 
 This little tool lists the usage of the incoming and outgoing buffers of the UDP socket belongs to the specified port, and the number of dropped packages.

 Example:
+
+```bash
 :~# ./udpstat.py 5001 -u 10
 Start collecting RX and TX queue statistics information and dropped packages result for port (5001)
