+%   Same as for copying, only small bits are missing here.  Namely, two
+%   token lists that tell the \pkg{ltcmd} mechanism how to deal with the
+%   argument types defined here.  Both |G| and |u| are classified
+%   as~|3|: commands that take a default value.  That's not really true
+%   for~|u|, but it's a close enough approximation to get the output we
+%   want.
