+The script checks that you have `mplayer(1)` installed and if it is it will pipe
+`vik` to `mplayer`. In this case it will also use `raw2wav` to convert the file
+to a WAV file. If `mplayer(1)` cannot be found it will just use `raw2wav`. This
+way even if one has an `mplayer(1)` that fails or is for some reason not what is
