# comment.: usable for 
#			mp3blaster ( use -f ${npfile} )
#			xmms ( song_change Plugin: action: echo "%s" > "${npfile}",
#			the output format can be changed, but leave the defaults
#			for this script. Activate the Plugin.
#			cmus (no changes needed)
#		
#	    output format is: ``np: $Artist - $Title''
#	    if there are any bugs / problems, don't shoot the messenger.
#		NOTE: mp3blaster puts filename as current title if no ID3 Tag was
#		found. np.sh will return ' - ' in this case!

# point to the status file
