finding locations of many files via kpse

Hi Deyan,

nice to see you here ;-) Thanks for your answer.

Yes, I am aware of that. But also least in convenience ;-)

What is the state of it? Instead of writing my own C-code, I could look
into using your rust wrapper, but AFAIS there is no cmd line interface
like asking for many files.

Yes. I still think it might be quite fast. A first run checking all
files, keeping the full response in memory, then checking for missing
files.

I think the kpsewhich binary is probably the fastest way by itself.
Maybe I look into kpsewhich and an options to output a different format
where missing files are easily distinguished.

And how would help that?

Best regards
