>From what I've read, there's (a) the Austin Group source for the documents,
which is written in troff; they render it (apparently using some AT&T
troff derivative) to (b) PDF and (c) HTML. They provided the troff source
to Micheal Kerrisk, who has added appropriate notices and distributed that
as man-pages-posix-2013.
