 # This workflow will run the benchmarks defined in the environment variable BENCHMARKS.
 # It will collect and aggreate the benchmark output, format it and feed it to github-action-benchmark.
 #
 # The benchmark charts are live at https://input-output-hk.github.io/plutus/dev/bench
 # The benchmark data is available at https://input-output-hk.github.io/plutus/dev/bench/data.js
