Agreed with this. Is there any mileage in considering the idea of a generic bit in the option-parsing code that has a table of mappings from legacy-style-simple-option to complex-set-of-device-etc options, so we can retain userfriendliness without per-kind-of-thing special casing, or is that too simplistic to work ? thanks -- PMM
