Where should the change be made to make auctex-emacs (up-to-date sid) call tex instead of latex? >From the auctex manual: When invoking one of the commands TeX-command-master (C-c C-c) or TeX-command-region (C-c C-r) LaTeX is run on either the entire current document or a given region of it. I haven't seen any reference to Plain. Anybody knows? Thank you in advance.
