[NTG-context] ConTeXt and emacs

Dear co-listers, I'm (very slowly) trying to use emacs with ConTeXt. I have tried Berend de Boers context.el which offers a good many nice features, but I couldn't find for the life of me how to do a couple of things (such as run texexec on the file I'm editing). A while ago, Patrick mentioned that new versions of auctex will be context-aware, but the "stable" version I dlded knew nothing about ConTeXt. Has anybody succeeded in installing a new version that's working? Any how-tos about it? Best Thomas
