When I throw an Exception in an controller to see what would happen, I
saw a page with a lot of information, such as call stack, local
varials, and so on.
Of course it's very useful to solve problems when developing, but it's
so weired that there is no document about this.
Is it part of Turbogears or CherryPy?
