+=item --keys
+
+Show the hash keys that differ between the two files, useful merging
+new entries from F<en.yml> to a local file.
+
+=item --untranslated-values
+
+Show keys whose values are either exactly the same between the two
+files, or don't exist in the target file (the latter file specified).
+
+This helps to find untranslated values.
