Yeah, I started out with something like this. Then I added provisions for embedding images, literal TeX syntax that could extend to more than one lines, inlined gnuplot scripts, etc., and it became pretty much unmaintainable.

But you are perhaps right, I should at least have a go at refactoring the existing script using idioms I'm familiar with, before I jump into rewriting it with a tool I don't know (P::RD).
