You might be thinking of Holide. There is a link at
http://dedukti.gforge.inria.fr/, but it seems to be 404 at the moment. Ask
Another possibility is https://www.lri.fr/~keller/Recherche/hollightcoq.html,
but I think it's only one-way (and not the direction you need).

I am interested in producing a writer for Isabelle/HOL eventually (some
time over the next year hopefully). It could be good to combine efforts.

Writing proofs in HOL4 or HOL Light is not as frightening as you might

If you work in a restricted subset of Coq, it may be possible to create a
translation from Coq's proof terms to OpenTheory format. It might be worth
looking into that, if you're interested. Let me know.
