 A simple tester that uses strategy lists from files. Strategies must be on separate lines; line breaks within a single strategy are not allowed. Separate lists are used for different protocols: `list_http.txt`, `list_https_tls12.txt`, `list_https_tls13.txt`, and `list_quic.sh`. These files support comments starting with `#`.
