    -f, --force                      Overwrite files that already exist.

    -q, --quiet                      Suppress normal output.
    -t, --backtrace                  Debugging: show backtrace on errors.
    -h, --help                       Show this help message.
    -c, --svn                        Modify files with subversion. (Note: svn must be in path)

Description:
    The scaffold generator creates a controller to interact with a model.
    If the model does not exist, it creates the model as well.  The generated
    code is equivalent to the "scaffold :model" declaration, making it easy
    to migrate when you wish to customize your controller and views.

    The generator takes a model name, an optional controller name, and a
    list of views as arguments.  Scaffolded actions and views are created
    automatically.  Any views left over generate empty stubs.

    The scaffolded actions and views are:
        index, list, show, new, create, edit, update, destroy

    If a controller name is not given, the plural form of the model name
    will be used.  The model and controller names may be given in CamelCase
    or under_score and should not be suffixed with 'Model' or 'Controller'.
    Both model and controller names may be prefixed with a module like a
    file path; see the Modules Example for usage.

Example:
    ./script/generate scaffold Account Bank debit credit

    This will generate an Account model and BankController with a full test
    suite and a basic user interface.  Now create the accounts table in your
    database and browse to http://localhost/bank/ -- voila, you're on Rails!

Modules Example:
    ./script/generate scaffold CreditCard 'admin/credit_card' suspend late_fee

    This will generate a CreditCard model and CreditCardController controller
    in the admin module.

Rails Info:
    -v, --version                    Show the Rails version number and quit.
    -h, --help                       Show this help message and quit.

Description:
    Scaffolds an entire resource, from model and migration to controller and
    views, along with a full test suite. The resource is ready to use as a
    starting point for your restful, resource-oriented application.

    Pass the name of the model, either CamelCased or under_scored, as the first
    argument, and an optional list of attribute pairs.

    Attribute pairs are column_name:sql_type arguments specifying the
    model's attributes. Timestamps are added by default, so you don't have to
    specify them by hand as 'created_at:datetime updated_at:datetime'.

    You don't have to think up every attribute up front, but it helps to
    sketch out a few so you can start working with the resource immediately.

    For example, `scaffold post title:string body:text published:boolean`
    gives you a model with those three attributes, a controller that handles
    the create/show/update/destroy, forms to create and edit your posts, and
    an index that lists them all, as well as a map.resources :posts
    declaration in config/routes.rb.
Examples:
    `./script/generate scaffold post` # no attributes, view will be anemic
    `./script/generate scaffold post title:string body:text published:boolean`
    `./script/generate scaffold purchase order_id:integer amount:decimal`

という事で、1(1.2)系と2系では結構違いがある。
