access different Unix's man pages locally from Emacs

[Emanuel Berg]

If you have access to other Unix systems, it is
likely you run into problems because they don't use
GNU programs. To read a man page over ssh isn't sharp
compared to doing it with the No. 1 Emacs instance -
IMO - so I got the whole thing and put it to
/usr/share/man/ with a sensible name (i.e., openbsd
and sunos), then you can access it from the local
shell with 'man -m openbsd ls' or 'man -m sunos ls'
for the OpenBSD 6.6 (ah, actually they didn't update)
and SunOS 5.10 ls man pages, respectively.

Here is the code - _not complicated_ in terms of code
but very useful.

(defun man-openbsd (page)
  (interactive "spage: ")
  (man (concat "-m openbsd " page) ))
(defalias 'mano #'man-openbsd)

(defun man-sunos (page)
  (interactive "spage: ")
  (man (concat "-m sunos " page) ))
(defalias 'mans #'man-sunos)

Some technobabble while I did this:

    <incal> yeah! got the SunOS man pages working,
            'sudo cp man /usr/share/man/sunos' then
            'man -m sunos ls' to get the SunOS 5.10
            ls(1) man page! OK, so we know Linux and
            GNU people are maximalists under the hood
            of minimalism
            <https://dataswamp.org/~incal/swamp-imgs/incal-desktop.png>,
            OpenBSD people are correct and secure ...
            which seems to mean (in part) fewer packs
            and very few options compared to the GNU
            toolchain - but many options seems to
            
    <incal> be the case for SunOS as well! GNU ls man
            page lines: 253, BSD ditto: 291,
            SunOS: 737 (!)
