+D: Manipulate the afs entry of audio files.
+U: touch [-n=numplayed] [-l=lastplayed] [-y=lyrics_id] [-i=image_id] [-a=amp] [-v] [-p] pattern
+H: If no option is given, the lastplayed field is set to the current time
+H: and the value of the numplayed field is increased by one. Otherwise,
+H: only the given options are taken into account.
+H:
+H: Options:
+H:
+H: -n Set the numplayed count, i.e. the number of times this audio
+H: file was selected for streaming so far.
+H:
+H: -l Set the lastplayed time, i.e. the last time this audio file was
+H: selected for streaming. The argument must be a number of seconds
+H: since the epoch. Example:
+H:
+H: touch -l=$(date +%s) file
+H:
+H: sets the lastplayed time of 'file' to the current time.
+H:
+H: -y Set the lyrics ID which specifies the lyrics data file associated
+H: with the audio file.
+H:
+H: -i Like -y, but sets the image ID.
+H:
+H: -a Set the amplification value (0-255). This determines a scaling
+H: factor by which the amplitude should be multiplied in order to
+H: normalize the volume of the audio file. A value of zero means
+H: no amplification, 64 means the amplitude should be multiplied
+H: by a factor of two, 128 by three and so on.
+H:
+H: This value is used by the amp filter.
+H:
+H: -v Verbose mode. Explain what is being done.
+H:
+H: -p Pathname match. Match a slash in the path only with a slash
+H: in pattern and not by an asterisk (*) or a question mark
+H: (?) metacharacter, nor by a bracket expression ([]) containing
+H: a slash (see fnmatch(3)).
