+provides a convenient way to defer text evaluation in a way that can
+be easily integrated into existing mode-line's without requiring a
+minor mode or configuration.
+
+Mode Line Idle helps to add useful information into the mode-line
+without slowing down Emacs performance.  While delaying updates is not
+so difficult, having multiple timers can become awkward when mixed in
+with the mode-lines configuration.  Instead of avoiding expensive
+information in the mode-line, it can be calculated when idle.")
