(For those on the TUHS list wondering about context, here it is. I
"ported" the document in the Subject line to groff and re-typeset it,
discovering some spacing nits in groff and, apparently, a bug in AT&T
troff as well--one equation[1] in the sources not appearing in published
versions has risen from the grave when rendered with groff.

If V10 was formally released, then yes - I would make

and feel free to say it to the judge.
That said, did Caldera (and/or Nokia) officially release it or are
they just 'not noticing' that it is available in the wild?
I was under the impression that the only thing official is through V7.
But all the other versions have 'leaked' and are widely available, and
whoever owns that IP at this point, is not pursuing protection. I am
aware that Caldera ended up with rights of 'UNIX' - certainly through
SVR5 -- and they released V1-V7 and 32V under their license (pointed
too in the earlier message). However, I am ownsnot aware of who
formally owns V8-V10 (I would assume Caldera also but that IP might
have stayed with Lucent then Nokia as part of that BTL IP transfer].
Also, did Nokia 'formally' release Plan9 or Inferno -- is there a
document like the Caldera one?
I believe even early releases of Plan 9 and Infero are both now fully
liberated, though the former[2] took much longer than the latter[3].
I'd offer my thanks to anyone who is keeping the Plan 9 and Inferno
flames lit.
