+Overriding the status line
+--------------------------
+
+Some users may wish to override the status line, e.g. with recording time.
+If so, it is possible (since Nageru 1.9.1) to declare a function **format_status_line**::
+
+  function format_status_line(disk_space_text, file_length_seconds)
+    if file_length_seconds > 86400.0 then
+      return "Time to make a new segment"
+    else
+      return "Disk space left: " .. disk_space_text
+    end
+  end
+
+As demonstrated, it is given the disk space text (that would normally
+be there), and the length of the current recording file in seconds.
+HTML is supported.
