Thanks for getting back with answers to my dumb questions and sorry for the
noise.

I went ahead and submitted (what became) sage-bin-8.3 (thanks for all the work,
mods) and it's been on SBO for just over a month now.

I guess I should have posted to this thread about that :/

It's a package of the Debian tarball as you suggested, installs (a symlink) in
/usr/bin works from anywhere etc. etc.

I did try some plots and they looked fine, but mostly I just (mis-)use it to do
proper-fraction arithmetic - it's great!

Cheers ... Duncan.
