Been thinking about it a little recently, and, no, I definitely don't plan
to send my stuff to a scrapper. I have some younger friends with an
interest in retrocomputing. They want my stuff when I'm done with it,
sure. And if they want _just a little_ of my stuff I'll probably strike a

Have you considered sqlite3? It's a SQL engine, but the backend is just a
file. So it doesn't support concurrent access by multiple users, but if
that's not a concern, it gives you the ability to do real SQL queries

I have heard rumors of one "fredmacs" which is a more-or-less emacs that
