webapp2.Route(r"/<n:.*>", handler=Handler)
], debug=True)
app.error_handlers[400] = partial(handle_error, code=400)

## Warning

Make sure you only use MarkII in development mode.

## Gotchas

On AppEngine, you must call `markii.appengine.fix_appengine()` inside
your error handler.

## Text editor support

MarkII supports opening files in your editor when you double click a
frame by taking advantage of OSX's URL handler feature. See:

MarkII borrows its ideas (and most of its look) from [better_errors](https://github.com/charliesome/better_errors).
