+# ----------------------------------
+# Usage: tooling/import_benchmark/benchmark.sh <NETWORK> <NUM_REPETITIONS>
+#
+# Arguments:
+#   <NETWORK>         Name of the network to use (e.g.: 'mainnet', 'hoodi', 'sepolia').
+#   <NUM_REPETITIONS> Number of times to run the benchmark (positive integer).
+#
+# Description:
+#   This script runs the import benchmark repeatedly and saves each run's output
+#   to an incrementally numbered log file named `bench-<id>.log`.
+#
+# Example:
+#   ./tooling/import_benchmark/benchmark.sh mainnet 5     # run 5 repetitions with mainnet
+#   ./tooling/import_benchmark/benchmark.sh mainnet 5 10  # same, but start with bench_id 10
+#
