This turns out to be fairly easy. This markup:
"""Return an IResponse or a deferred which will fire an
IResponse. This response will be written to the web browser
which initiated the request.
@errback FooError: if it's too fooey.
@errback BarError: if there is any bar; this is foo, not bar.
@errback HolyCrapError: if your pants are on fire.
(function chosen entirely at random) produces this output:
Producing something better than "Unknown Field: errback" is a matter
of a little typing; ideas welcome :)
I believe C++ instills fear in programmers, fear that the
interaction of some details causes unpredictable results.
