Done.

-  Directory startingDir = script.parent.parent.parent.parent;
+  Directory startingDir = script.parent.parent.parent;
+  print("Recursively listing entries in directory ${startingDir.path} ...");

do we really need this?

It helped me understand what's going on. I can take it out if it interferes with
anything in the test harness.

   List<FileSystemEntity> each =
       startingDir.listSync(recursive: true, followLinks: false);
   print("Found: ${each.length} entities");
