(define-minor-mode emacs-lock-mode
  "Toggle Emacs Lock mode in the current buffer.
If called with a plain prefix argument, ask for the locking mode
to be used.

Initially, if the user does not pass an explicit locking mode, it
defaults to `emacs-lock-default-locking-mode' (which see);
afterwards, the locking mode most recently set on the buffer is
used instead.

When called from Elisp code, ARG can be any locking mode:

 exit   -- Emacs cannot exit while the buffer is locked
 kill   -- the buffer cannot be killed, but Emacs can exit as usual
 all    -- the buffer is locked against both actions

Other values are interpreted as usual.

See also `emacs-lock-unlockable-modes', which exempts buffers under
some major modes from being locked under some circumstances."
