The -R option specifies a rotation about the origin. If the argument is
six values this is a rotation of a 'from' vector (the first three numbers)
onto a 'to' vector (the second set of three numbers) about a axis
perpendicular to the two vectors. In this example aligning a vertex
of a cube with the z-axis the rotations does not nicely align the
cube with the x and y axes, for that see the 12 parameter rotation.
