scaffold method versus script/generate scaffold

For the following:

"If you have a controller named ‘Entry’, and model named ‘Post’, it can
be used as follows:

class EntryController < ApplicationController
  scaffold :post
end"

<http://wiki.rubyonrails.org/rails/pages/Scaffold>

Are they saying to create railsProject/app/controllers/entry_controller?
And, wouldn't it be railsProject/app/controllers/entries_controller?

thanks,
