 tim i never used configparser before but i read that its read method silently ignores files that don t exist if bayes ini isn t found none of the options will be defined note that i since got rid of bayes ini it s embedded in URL now so search path issues won t burn you here anymore the intended way to customize the tokenizer and testers is via creating your own bayescustomize ini you ll get burned by search path issues wrt that instead now NUMBER NUMBER wink
