Could you make your latest sentence more explicit?

I guess things in that direction are entirely possible. I don't use bibtex
yet, but will have a look at a better integration.

Good question! Yes, I implicitly wrote in bash. That won't work for sure in
Windows...
But, then, how do we do for writing such shells in Emacs? Go to Emacs's
builtin shell? I have no experience with it, but I can have a look, except:
how would we be sure that the preferred shell of the user is that one?

For sure, such behaviors would be a great, in case of failures.
