(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.

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.
