For technical reason, I had to set for using emacs as my working environment, as I am able to type directly some Unicode signs that otherwise I cannot code in with Texworks or TeXmaker. At this point, I would like to use xelatexmk in emacs. I have seen some of the actual threads about Latexmk, but I am not really sure how to implement xelatexmk in emacs anyway.
My emacs is the last version in Windows (emacs 23.3) and I am using TeXlive. My .emacs is quite basic and I can post it if it needed. I am asking this question as Ancient Historian working with emacs. While I am only asking for a simple setting, I am also raising the point as they might be other users trying to use emacs and latexmk with xelatex, so any answer will be retrievable on line.
