configure auctex with miktex's command line options

[Olaf]

Hi,

miktex can have an optional argument command line argument for
separating aux files into an own directory
(http://docs.miktex.org/manual/texfeatures.html#auxdirectory). How can I
set this for auctex? I have to set bib-cite-aux-inputs as well (as far
I've read). The best would be to make the aux file directory locally to
the latex project directory tree where the text master file resist.

Thanks,
Oalf
