 <h2>reverseapi.py</h2>
 
 This script runs continuously to act as the server side of SDRangel reverse API feature. It will respond with a copy of the settings when forwarding channel or device settings which is a valid reply and will also send back a valid reply when forwarding the device start/stop actions. The reverse API feature was implemented in version 4.3.2 and you can learn more about it in the Wiki.
