That's both harsh and completely unfair. In fact, I think the Log::Log4perl documentation is both extensive and well written. Courtesy never hurts, and sometimes helps.
I am happy you feel this way about the massively incomplete documentation. Just to prove my point - tell me where in the docs is .Threshold being discussed? Certainly not in Log::Log4perl, nor in Log::Log4perl::Config (the only two places where a seasoned CPAN user would look). The only place I found this modifier (after your hint) was in the FAQ, and even then - it was in sections completely unrelated to my problem.
Thank you, nevertheless, for pointing me in the right direction. I stand by my words however.
