-    -r, --runner TYPE                Specify runner type: ips, time, memory, once (default: ips)
-    -o, --output TYPE                Specify output type: compare, simple, markdown, record (default: compare)
+    -r, --runner TYPE                Specify runner type: ips, time, memory, once, block (default: ips)

         --repeat-count NUM           Try benchmark NUM times and use the fastest result or the worst memory usage
         --repeat-result TYPE         Yield "best", "average" or "worst" result with --repeat-count (default: best)
+        --alternate                  Alternate executables instead of running the same executable in a row with --repeat-count
