This is the set of Perl scripts that does all of the regular updating on Flutterby™! It's still very alpha, but I think I've got most of the big bugs out.
Short summary: Newwwsboy takes e-mail or text files as input and, using comments in HTML documents as a template, formats the e-mail and stuffs it into those documents.
Current docs are online.
The names of these documents can also have replaceable parameters, like the month, or the day, and if that means a new document gets made then the links from other documents get inserted automatically.
Don't bother downloading this unless you can at least install Perl on your computer. But beyond that, I'd love to see a couple of users for this and am happy to help with questions.
