Yes - the handle_exception() method on the Application mixin attempts to
run the template "traceback.html", and only if that fails (doesn't exist,
or produces an exception) does it display the traceback to the user.

The python and template tracebacks are available to the template in
python_exc and html_exc respectively.

Alternatively, if you want to do something this framework doesn't allow,
you can define you own handle_exception() method on your application
class.

Albatross tries to make it's source accessible for extension - have a look
at the Application class in app.py to see how this machinery works.
