If you are a technical person and so a past, present, or potential
RFC author, you will have your own systems and chances better than
even that at least some of them will have `man` and `nroff`.
A draft formatted with Word recently crossed my
path, and the formatting was *so* bad that the
document wasn't readable (for some reason something
in the Word -> text process deleted all vertical
whitespace). I reformatted it with nroff under
UWIN, which really worked very well and held no
surprises whatsoever. So, it's not even necessary
to have access to a Unix or Unix-ish OS to use
nroff for document production.
