[Zope-dev] Deprecation Warning

Hi everybody, While porting Zope2 on Python2.5, I am now trying to remove the deprecation warnings.Most of them are due to the raising of string exceptions. One of such warnings in the module Products is /home/zope/ztrunk25/lib/python/OFS/SimpleItem.py:248: DeprecationWarning: raising a string exception is deprecated raise error_type, v, tb These warnings can be removed by changing these string exceptions to class based exceptions. Can anyone suggest how these changes can be made? With regards Vyshakh
