What's the point of this tool here exactly?

Oops, that was a temp script for me. Didn't mean to add it. Deleted.

+  for (var path in listFiles("language_2", extension: ".status")) {
+    var file = new StatusFile.read(path);
+    print(path);
+    for (var section in file.sections) {
+      var splits = filesForHeader(section.condition.toString());
+      if (splits.length > 1) {
+        print("${section.lineNumber}: [ ${section.condition} ]");
+        print("  " + splits.join(" "));
+      }
+    }
+  }
