  The formulae relevant for the Linear Optics design of Synchrotrons are
derived systematically from first principles, a straightforward exercise in
Hamiltonian Dynamics. Equipped with these, the relevant "Use Cases" are then
captured for a streamlined approach. This will enable professionals -- Software
Engineers -- to efficiently prototype & architect a CAD Tool for ditto;
something which has been available to Mechanical Engineers since the mid-1960s.
