+	  Gqrx is an open source software defined radio (SDR) receiver
+	  implemented using GNU Radio and the Qt GUI
+	  toolkit. Currently it works on Linux and Mac with hardware
+	  supported by gr-osmosdr, including Funcube Dongle, RTL-SDR,
+	  Airspy, HackRF, BladeRF, RFSpace, USRP and SoapySDR.
+
+	  Gqrx can operate as an AM/FM/SSB receiver with audio output
+	  or as an FFT-only instrument. There are also various hooks
+	  for interacting with external application using network
+	  sockets.
