 Print this help message.
 
+=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). The values are pruned according to global and language
+specific blacklists found in the C<__DATA__> section of this script.
+
+This helps to find untranslated values.
+
+=item --untranslated-values-all
+
+Like C<--untranslated-values> but ignores blacklists.
