+description:
+ quickbench produces very simple output (elapsed seconds),
+ as quickly as possible (running commands just once by default),
+ and tabulates results from multiple executables.
+ I find it very useful for quick and dirty, exploratory, and comparative measurements
+ that you can understand at a glance.
+ Please see the readme for more.
