[auctex] Setting TeX-command-list

[Olaf]

Hi,

I've emacs/win32 to use MikTeX's aux-directory feature - even wrong:

site-lisp/site-start.d/auctex.el:

(add-hook 'LaTeX-mode-hook
        (function (lambda ()
                (add-to-list 'TeX-command-list '("TeX" "%(PDF)%(tex)
%`%S%(PDFout)%(mode)%' %t" TeX-run-TeX t (plain-tex-mode texinfo-mode
ams-tex-mode) :help "Run plain TeX"))
                (add-to-list 'TeX-command-list '("LaTeX" "%`%l 
-aux-directory=./auxil
%(mode)%' %t" TeX-run-TeX nil (latex-mode doctex-mode) :help "Run LaTeX"))
...
                (add-to-list 'TeX-command-list '("BibTeX" "bibtex
-include-directory=./auxil %s" TeX-run-BibTeX nil t :help "Run BibTeX")
("View" "%V" TeX-run-discard t t :help "Run Viewer"))
...
)))

Some of the entries appears twice in the config. How can I overwrite
them here? How can I enfore the existence of the directory - even create
on demand?

Thanks,
Olaf
