I've found the TestCommon::LogDiff package in the mod_perl unit tests to be useful in testing my own mod_perl-based packages, and I can see how it would be useful in lots of other applications as well.
Could a separate distribution (Test::LogDiff, say) be made out of it so that it's easily re-used anywhere? It's already got a bit of pod, it just needs a few tests and some packaging up and it's ready to go. I'd gladly take this on if I have the authors' blessing. Cheers, Tyler
