How do I use Flickzeug to get interactive tracebacks from a paste deploy WSGI pipeline?

I'd like to use Flickzeug to see interactive tracebacks by adding it to my paste deploy file's 开发者_开发百科pipeline. The following doesn't work. What will?

[pipeline]
pipeline =
    flickzeug
    myapp

Use the filter-with directive in your application declaration.

[app:main]
use = ...
...

filter-with = flickzeug


[filter:flickzeug]
use = egg:...#...
...

For more information, see the first example in the Filter Composition section of the Paste Deploy documentation.
