Sorry, I meant the man-pages style guide rules, not roff itself.

I just meant for semantic context, like "this is a code snippet" vs "I
want this to be formatted the way I typed it."  Might be helpful when
outputting HTML/CSS, like the examples would be in boxes and shaded with
the usual "copy to paste buffer" button, but <pre> would just be
monospaced and unformatted.  But thus is the slippery slope that led to
XML, and we don't want that again.

My preference here is PDF, as we make sure all the cross refs and TOC
work correctly, and it formats very nicely (duh, TeX).  Info is useful
in emacs only because my fingers are already on the keyboard.

I've been accused of abusing my own namespace here.  I would have called
my version "djrout".

I once worked for a guy who, at one point, wrote a typesetter that went
between satellites and the New York Times.  The typesetting had to be
perfect, every time, and run at line speed.  I learned a lot from him,
and he's the reason I have my own copy of the Chicago Manual of Style
and know what Reverse Boustrophedon is.

Also, Team Oxford Comma!

RHEL 9 has "man -l" via man.man-db at least, but that's today.
