+ (description
+ "The @code{time} utility is a simple and often effective way of measuring
+how long a command takes to run (wall time). Unfortunately, running a command
+once can give misleading timings. @code{multitime} is, in essence, a simple
+extension to @code{time} which runs a command multiple times and prints the
+timing means, standard deviations, mins, medians, and maxes having done so.
+This can give a much better understanding of the command's performance.")
