"""Displays information about the current song in cmus.
Requires the following executable:
* cmus-remote
Parameters:
* cmus.format: Format string for the song information. Tag values can be put in curly brackets (i.e. {artist})
Additional tags:
* {file} - full song file name
* {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'
* cmus.layout: Space-separated list of widgets to add. Possible widgets are the buttons/toggles cmus.prev, cmus.next, cmus.shuffle and cmus.repeat, and the main display with play/pause function cmus.main.
* cmus.server: The address of the cmus server, either a UNIX socket or host[:port]. Connects to the local instance by default.
* cmus.passwd: The password to use for the TCP/IP connection.
