+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.
