description         ${name} is used to interface to the Industrial Input/Output (IIO) Subsystem
long_description    {*}${description}. The 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.
