+The above command downloads the artifacts of clang crash diagnoses and send them
+to 4c server for bisection. The summary of submitted jobs will be saved in
+output/state.json under the current path. The output directory will be created
+automatically if it does not exist yet. To get more information of the submitted
+jobs, please refer to go/4c-cli.
+
+Note that it's recommended to 'seed' the state file with a most recent upload
+date. This can be done by running this tool *once* with a `--last_date` flag.
+This flag has the script override whatever's in the state file (if anything) and
+start submitting all crashes uploaded starting at the given day.
