 module ActionController #:nodoc:
-  # Actions that fail to perform as expected throw exceptions. These
-  # exceptions can either be rescued for the public view (with a nice
-  # user-friendly explanation) or for the developers view (with tons of
-  # debugging information). The developers view is already implemented by
-  # the Action Controller, but the public view should be tailored to your
-  # specific application.
-  #
-  # The default behavior for public exceptions is to render a static html
-  # file with the name of the error code thrown.  If no such file exists, an
-  # empty response is sent with the correct status code.
-  #
-  # You can override what constitutes a local request by overriding the
-  # <tt>local_request?</tt> method in your own controller. Custom rescue
-  # behavior is achieved by overriding the <tt>rescue_action_in_public</tt>
-  # and <tt>rescue_action_locally</tt> methods.
