+  WiFi Status
+
+ This sketch runs a script called "pretty-wifi-info.lua"
+ installed on your Yún in folder /usr/bin.
+ It prints information about the status of your wifi connection.
+
+ It uses Serial to print, so you need to connect your Yún to your
+ computer using a USB cable and select the appropriate port from
+ the Port menu
+
+ created  18 June 2013
+ By Federico Fissore
