I think so.  I assume we can work out some way to do it and/or asciidoctor 
will add support for it if they expect to capture a big chunk of the man page 
market.

Google is good at finding man pages.  Many of them are not recent.  It would 
be nice to be able to easily see what version we are looking at.

Humm... I just noticed that most man pages have something in the middle of 
the top line where our man pages are blank.

man 3 open, Fedora:
OPEN(3P)                   POSIX Programmer's Manual                  OPEN(3P)

man ntp.keys:
NTP.KEYS(5)                                                        NTP.KEYS(5)
