@clew I tried LaTeX ten years ago and never learned how to get satisfactory output despite buying and reading Leslie Lamport's book.
Granted, LaTeX has probably changed considerably over the last decade or so, but I was able to install groff on my laptop in 15 seconds. The macros look pretty straightforward if http://www.schaffter.ca/mom/momdoc/docprocessing.html#setup is any indication, so I hope to have a better experience.
Also, I figure using groff on OpenBSD will earn more hipster cred.
