generate scaffold or model for join table?

I'm using <http://wiki.rubyonrails.org/rails/pages/ThroughAssociations>
as a guide, but it doesn't say how to generate the model for the join
table. Which of the following would be preferable:

script/generate scaffold category_feeds

or

script/generate model category_feeds

So long as it's kosher, I prefer the scaffold generator. For now the
join table only has foreign keys for fields, but that may change down the
road.

you just need a model, unless you are going to have more then just the
link fields in the many table.

this explains with samples:

I might add fields to the category_feeds table, but for now it
strictly manages the many-to-many relationship between the categories
and feeds tables. If I run "script/generate model category_feeds" it
will generate the corresponding model? This won't paint me into a
corner if I want to add fields to this table down the road (so long as
I manage the "rake db:migrate" commands)?

There's nothing to be gained by "script/generate scaffold
category_feeds"?

Thanks. It's one small step at a time for me on this. I'll go with
generating a scaffold as it does more and doesn't cause harm.
