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.")
