+# This is a helper script for evaluating benchmarks that have been translated to

+# To use this script, call eval_lang.py.
+# The --directory argument is required, and tells the script where the benchmarks are located.
+# The --files argument is optional, and takes a list of numbers corresponding to the files to be evaluated.
+#
+# The script will print the results on each benchmark, and also write to results/lang.csv.
+# When the script completes, it will print a summary.
+#
+# Examples
+#
+# To run the entire benchmark suite:
+#   python3 src/eval_php.py --directory datasets/php-keep-code_davinci_001_temp_0.2-0/
+#
+# To run benchmarks 1, 2, and 3:
