Known Subclasses:

A base for error handling pages.

The idea is that you set the "handles" class attribute to the exception you handle. The exception has to match exactly, i.e., no isinstancing is done.

You also must set status to the HTTP status code the error should return.

All error pages have a failure attribute that's a twisted failure with all the related mess (e.g., tracebacks).

You have the status and message data methods.
