I'd hate to download a CPAN module that had that large of an example embedded in it.
I think we're talking past each other. I'm not expecting to use a single CPAN module that will just "do" everything. What I'm surprised is the lack of a finished Perl script posted somewhere on the Internet that reads emails in a useful manner. Useful being defined as providing the content in a readable format. No, I'm not implying it should cover every possible contingency. (And please don't split hairs on what "readable" means.) I think you some how got it stuck in your head that I was looking for a single module and went off on that tangent. If you know of something similar to your 6,000 line script posted somewhere, I'd be happy to look and learn from it.
