-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).
+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
+been merged.
+
+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.

+Check that interpolated Ruby i18n variables (C<{{foo}}> and
