Another possibility would be to add to the documentation all the instructions needed on how to properly configure `org-latex-pdf-process' with latexmk, for those users who wish to use bibtex or biblatex. Although latexmk is also useful for many packages that need multiple compilations, indexes, etc. Best regards, Juan Manuel
