+    Squeezelite is a small headless squeezebox emulator for linux using alsa audio output 
+    It is aimed at supporting high quality audio at multiple sample rates including 
+    44.1/48/88.2/96/176.4/192k/352.8/384kHz 
+    Supported codecs: mp3, flac, ogg, aac, (wma and alac via ffmpeg) 
+    Native support for PCM builtin
+    Optional support of DSD playback via PCM for DoP capable DAC
+    Optional resampling to match sound device
