       Description: 
       
       I am starting a periodic posting for something I wanted to do since a
       long time. Take a port in the tree and introduce it quickly. There are
       tons of ports in the tree that we don't know about. So, I will write
       frequently about ports that I use frequently and that I find useful,
       if you read this, maybe I will find a new tool to your collection of
       "useful program". :-)
       
       For a first one, I would like to present **net/bwm-ng**. Its name
       stands for “_BandWitch Monitor next-generation_”, it allows the
       user
       to watch in real-time the bandwith usage of the different network
       interfaces. By default, it will update the display every 0.5
       second. You can change the frequency of updating by pressing keys '+'
       and '-'.
       
       Let see the bindings of the interactive mode :
       
       - **'t'** will cycle between current rate, maximum peak, sum, average
         on 30 seconds.
       - **'n'** will cycle between data sources, on OpenBSD it defaults to
         "getifaddrs" and you can also choose "sysctl" or "netstat -i".
       - **'d'** will change the unit, by default it shows KB but you can
         change to another units that suits better your current data.
