+	A configurable text progressbar.
+	
+	Each atom consists of three characters: a literal §, an operator and a channel.
+	An operator is one of:
+	% - a percentage (value from 0 to 100, padded to three characters)
+	r - displays the raw value of the channel
+	z - displays the maximum (total) value
+	s - displays the rate of change in units/s
+	m - displays the rate of change in units/min
+	h - displays the rate of change in units/h
+	t - displays the elapsed time in s (use with uppercase channel to get an ETA)
+	T - displays the elapsed time in hh:mm:ss (use with uppercase channel to get an ETA)
+	any other character - a bar consisting of these characters filling the line so that
+	                      at 100% it fills the entirety of the remaining space
+	
+	A channel ID as a lowercase letter is the channel's actual value. An uppercase letter
+	is that channel's complement.
+	
+	Use §§ to display a literal §.
+	
+	Examples
+	========
+	Format: §%a [§=a>§ A] §tA
+	Output: 42 % [============>                  ] 27 s
+
+	Format: §%a (§ra/§ma) [§-a>§ A] §sa [§rb/§rB] (ETA §tA)
+	Output: 53 % (21.0/39.6 kf) [--------------------->                   ] 27.1 f/s [233/439 Mio] (ETA 00:11:26)
