pkg.m: drop check of nargout value, the interpreter already does that. * scripts/pkg/pkg.m: the interpreter already checks if there was any variable that got no value assigned, there's no need to make the code more complicated to cover that. Also, there's no point in calling describe() with different nargout since it doesn't check nargout.
