"""Displays information about the current song in mpd.
Requires the following executable:
* mpc
Parameters:
* mpd.format: Format string for the song information.
Supported tags (see `man mpc` for additional information)
* {name}
* {artist}
* {album}
* {albumartist}
* {comment}
* {composer}
* {date}
* {originaldate}
* {disc}
* {genre}
* {performer}
* {title}
* {track}
* {time}
* {file}
* {id}
* {prio}
* {mtime}
* {mdate}
Additional tags:
* {position} - position of currently playing song
not to be confused with %position% mpc tag
* {duration} - duration of currently playing song
* {file1} - song file name without path prefix
if {file} = '/foo/bar.baz', then {file1} = 'bar.baz'
* {file2} - song file name without path prefix and extension suffix
if {file} = '/foo/bar.baz', then {file2} = 'bar'
* mpd.host: MPD host to connect to. (mpc behaviour by default)
* mpd.port: MPD port to connect to. (mpc behaviour by default)
* mpd.layout: Space-separated list of widgets to add. Possible widgets are the buttons/toggles mpd.prev, mpd.next, mpd.shuffle and mpd.repeat, and the main display with play/pause function mpd.main.
