 # This workflow runs whenever a PR is opened or updated, or a commit is pushed to main. It runs
 # several checks:
-# - commit_list: produces a list of commits to be checked
 # - fmt: checks that the code is formatted according to rustfmt
 # - clippy: checks that the code does not contain any clippy warnings
 # - doc: checks that the code can be documented without errors
