That's a good start :-)

Yes, I noticed you were working on different lisp libraries around TeX 👍

This is definitely important.  You may have noticed that the general
author of preview is now inactive, and the library is in sort of
maintenance mode, so we have to be careful.

It sounds like a plan; gradually bringing in stuff you need is the way
to go.  Looking forward to your changes.
