-To compare a parameterized benchmark against a particular run, pass its exact printed name to
-`--reference`. For example:
-```sh
-hyperfine -L delay 0.2,0.4,0.6 --prepare 'sleep {delay}' --reference 'echo a (delay = 0.4)' 'echo a'
-```
-The name must identify exactly one benchmark, including any `--command-name` and displayed unused
-parameters. `--reference-name` cannot be used with parameterized benchmarks; use `--command-name`
-to name them instead. Without `--parameter-scan` or `--parameter-list`, `--reference` runs a
-separate reference command.

 If you need a unique value for each individual run of a benchmark command, hyperfine also exposes
 the zero-based `$HYPERFINE_ITERATION` environment variable inside the benchmarked command itself:
 ```sh
