+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 that B<exist in both the compared files> and whose values
+are exactly the same. Use C<--keys> to a list of values that hasn't

+
+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.

+=item --validate-variables
