I use Emacs and MikTeX. With the latter comes a PDFLaTeX option to move clutter in a temp-dir directory: -aux-directory temp-dir. I am tentatively trying to pass it to AUCTeX with:
(setq tex-start-options "-aux-directory temp-dir")
Doesn’t work! I am not very knowledgeable with AUCTeX internals. Can you give some hints and examples on LaTeX-command, latex-run-command, tex-start-options and tex-start-commands and the likes?
