Although I would normally hate to nit-pick a (parenthetical) comment,
I have to make an exception in this case.  I dont think that you want the
emacs interface to produce the illusion of a single program at all.
In the name of this illusion, the Quintus Prolog emacs interface has
the following "features":

    - You cannot start Prolog w/ interface if you are already in emacs.
      Prolog can only be called from the (in our case) unix prompt.

    - Many nice, handy emacs features have either been deformed or
      destroyed.  These include delete-window (why *cant* I take the
      prolog buffer off the screen for a while.  I know how to get
      it back), and shell (in our version, you couldnt run any other
      subprocess besides prolog, not even a clock).

Besides this, because the prolog/emacs interface was a separate
environment, Quintus felt free to make arbitrary changes to the
default key bindings that had nothing to do with prolog.
These include the kill-ring commands, and incremental search.

Thats all for now.

Now back to your regularly scheduled programming.
