+The squeezelite options are very similar to the regular squeezelite options. Differences are :
+	- the output is -o [BT <sinkname>] | [I2S]
+	- if you've compiled RESAMPLE option, normal soxr options are available using -R [-u <options>]. Note that anything above LQ or MQ will overload the CPU
+	- if you've used RESAMPLE16, <options> are (b|l|m)[:i], with b = basic linear interpolation, l = 13 taps, m = 21 taps, i = interpolate filter coefficients
