[texhax] tex filename backtrace utility

[Uwe Lück]

I was just looking through ctan.org/pkg for another thing and found "FiNK" 
again that provides a macro bearing the file currently processed. May this 
help? Personally, I find the README information about "FiNK" little 
helpful, it has not been the first time now. -- Uwe.
