    Coq's Emacs mode is installed into
      #{lib}/emacs/site-lisp

    To use the Coq Emacs mode, you need to put the following lines in
    your .emacs file:
      (setq auto-mode-alist (cons '("\\.v$" . coq-mode) auto-mode-alist))
      (autoload 'coq-mode "coq" "Major mode for editing Coq vernacular." t)
    EOS
