Yes, an `appendix' is probably the right term.  I didn't think to use
correct terminology.

Not sure what to make of that comment.  I mean, I never proposed
anything fullblown.  But maybe you are not referring to what I
suggested in OP above.  I only suggested the tools in libexec have an
entry in the index. I had in mind the kind of entry that can currently
be found with an `s' search for cvtmail. The one you see if you say `
`info emacs' then press `s' cvtmail<RET>.

Thats a good piece of info for someone trying to pare down.

Ok that confirms my guess.  I'm taking note of these for my next try.

I mentioned that tty colors didn't work after my experimental build.
That is what I meant by `failure'.  I thought maybe I nuked something
that caused that, like possibly etc/term.src.  But I see from your
comments that is not the case so must be something else.  Maybe the
obnoxious default termon FreeBSD (cons25).  Hopefully your pointer to
PROBLEMS will get me on the right track on that.

With these tips, I'll experiment further... Thanks
Have to wait until the machine is less busy.
