I know, but posting that much code at once, I felt sort of like the guy who's asked to do a wedding toast and goes on with a speech for half an hour. Here's two of the templates (out of eight, so there is a quantity of mercy here). The point would be to make your own, according to your own needs.

Second, in case any of you have ever seen GNU Lilypond, it is a cool music typesetting program. Although it isn't Perl, I had to do a lot of language learning before I could produce good copy with it. I'm proud of the result (template.ly). The syntax is similar to LaTeX:

And there you go; 'anew' can be adapted as stated in the original article, according to your needs.
