This might have been a typo: there is a family of LaTeX classes called
"koma" (not "korma", that's rather a family of Indian dishes ;-)

That said, I fail to find a korma-article.cls. So perhaps this wasn't
meant /literally/ by Tim, but rather a placeholder.

I think Tim is just furnishing examples, not a complete solution.

LaTeX is a world unto itself, and to fine-tune the results of your
LaTeX exporter (the PDF exporter is just a little appendix on that),
you'll have to dive a bit into that.

Or just ask around here, but best with concrete, little goals each
time.
