+     "Libiio is used to interface to the Linux Industrial Input/Output (IIO)
+Subsystem.  The Linux IIO subsystem is intended to provide support for devices
+that in some sense are analog to digital or digital to analog converters
+(ADCs, DACs).  This includes, but is not limited to ADCs, Accelerometers,
+Gyros, IMUs, Capacitance to Digital Converters (CDCs), Pressure Sensors,
+Color, Light and Proximity Sensors, Temperature Sensors, Magnetometers, DACs,
+DDS (Direct Digital Synthesis), PLLs (Phase Locked Loops),
+Variable/Programmable Gain Amplifiers (VGA, PGA), and RF transceivers.  You can
+use libiio natively on an embedded Linux target (local mode), or use libiio to
+communicate remotely to that same target from a host Linux, Windows or MAC
+over USB or Ethernet or Serial.")))
