Decorators use by the TurboGears controllers.
Not all of these decorators are traditional wrappers. They are much simplified
from the turbogears 1 decorators, because all they do is register attributes on
the functions they wrap, and then the DecoratedController provides the hooks
needed to support these decorators.

If you're doing an http post, you can also declare the desired
content type in the accept headers, with standard content type
strings.
By default expose assumes that the template is for html. All other
content_types must be explicitly matched to a template and engine.
The last expose uses the custom_format parameter which takes an
arbitrary value (in this case 'special_xml'). You can then use
the`use_custom_format` function within the method to decide which
of the 'custom_format' registered expose decorators to use to
render the template.

It is possible to have several :func:`paginate`-decorators for
one controller action to paginate several collections independently
from each other. If this is desired, don't forget to set the :attr:`use_prefix`-parameter
to :const:`True`.
:Parameters:
name
the collection to be paginated.
items_per_page
the number of items to be rendered. Defaults to 10
use_prefix
if True, the parameters the paginate
decorator renders and reacts to are prefixed with
"_". This allows for multi-pagination.
