scaffold - more than 1 model tied to a controller ?

When I use the scaffold generator, I only have the option of tying one
model to one controller. If I have multiple models, how do I get all
the models to have scaffolding generated for the one controller?

Would the following work:

script/generate scaffold Model1 Controller
script/generate scaffold Model2 Controller
script/generate scaffold Model3 Controller

or would the following be better:
script/generate model Model1
script/generate model Model2
script/generate model Model3
script/generate scaffold Model1 Controller # which model to use?

and what happens if I create more models that I need to have scaffolding
built for my current controller? How would I integrate this new model
into the controller with scaffolding? Would this be one of those
instances where I need to do it by hand? Or am I missing something?

Thanks
