[pypy-dev] do we still need to generate applevel _exceptions.py?

Hi pypy-dev, We have pypy/lib/_exceptions.py which is a generated applevel definition and gets translated to pypy/module/exceptionsinterp.py by Christian fine geninterp mechanism. Now to fix some remaining compliancy bugs it seems easy to fix the applevel exceptions definition unless there is a need to still be able to regenerate that as well. I'd guess the latter is not neccessary anymore so is it fine to just fix pypy/lib/_exceptions.py and regenerate? And what was the incantation again to regenerate the exceptionsinterp.py again (did i miss some piece of documentation somewhere)? cheers, holger
