 @cindex buffer-local variables
 
   Global and local variable bindings are found in most programming
-languages in one form or another.  Emacs, however, also supports additional,
-unusual kinds of variable binding: @dfn{buffer-local} bindings, which
-apply only in one buffer, and @dfn{frame-local} bindings, which apply only in
-one frame.  Having different values for a variable in different buffers
-and/or frames is an important customization method.

-  Just as variables can have buffer-local bindings, they can also have
-frame-local bindings.  These bindings belong to one frame, and are in
-effect when that frame is selected.  Frame-local bindings are actually
-frame parameters: you create a frame-local binding in a specific frame
-by calling @code{modify-frame-parameters} and specifying the variable
-name as the parameter name.
-
-  To enable frame-local bindings for a certain variable, call the function
-@code{make-variable-frame-local}.
-
-@deffn Command make-variable-frame-local variable
-Enable the use of frame-local bindings for @var{variable}.  This does
-not in itself create any frame-local bindings for the variable; however,
-if some frame already has a value for @var{variable} as a frame
-parameter, that value automatically becomes a frame-local binding.
-
-If @var{variable} does not have a default value, then calling this
-command will give it a default value of @code{nil}.  If @var{variable}
-already has a default value, that value remains unchanged.
-
-If the variable is terminal-local, this function signals an error,
-because such variables cannot have frame-local bindings as well.
-@xref{Multiple Displays}.  A few variables that are implemented
-specially in Emacs can be buffer-local, but can never be frame-local.
-
-This command returns @var{variable}.
-@end deffn
-
-  Buffer-local bindings take precedence over frame-local bindings.  Thus,
-consider a variable @code{foo}: if the current buffer has a buffer-local
-binding for @code{foo}, that binding is active; otherwise, if the
-selected frame has a frame-local binding for @code{foo}, that binding is
-active; otherwise, the default binding of @code{foo} is active.
-
-  Here is an example.  First we prepare a few bindings for @code{foo}:
-
-@example
-(setq f1 (selected-frame))
-(make-variable-frame-local 'foo)
-
-;; @r{Make a buffer-local binding for @code{foo} in @samp{b1}.}
-(set-buffer (get-buffer-create "b1"))
-(make-local-variable 'foo)
-(setq foo '(b 1))
-
-;; @r{Make a frame-local binding for @code{foo} in a new frame.}
-;; @r{Store that frame in @code{f2}.}
-(setq f2 (make-frame))
-(modify-frame-parameters f2 '((foo . (f 2))))
-@end example
-
-  Now we examine @code{foo} in various contexts.  Whenever the
-buffer @samp{b1} is current, its buffer-local binding is in effect,
-regardless of the selected frame:
-
-@example
-(select-frame f1)
-(set-buffer (get-buffer-create "b1"))
-foo
-     @result{} (b 1)
-
-(select-frame f2)
-(set-buffer (get-buffer-create "b1"))
-foo
-     @result{} (b 1)
-@end example
-
-@noindent
-Otherwise, the frame gets a chance to provide the binding; when frame
-@code{f2} is selected, its frame-local binding is in effect:
-
-@example
-(select-frame f2)
-(set-buffer (get-buffer "*scratch*"))
-foo
-     @result{} (f 2)
-@end example
-
-@noindent
-When neither the current buffer nor the selected frame provides
-a binding, the default binding is used:
-
-@example
-(select-frame f1)
-(set-buffer (get-buffer "*scratch*"))
-foo
-     @result{} nil
-@end example
-
-@noindent
-When the active binding of a variable is a frame-local binding, setting
-the variable changes that binding.  You can observe the result with
-@code{frame-parameters}:
-
-@example
-(select-frame f2)
-(set-buffer (get-buffer "*scratch*"))
-(setq foo 'nobody)
-(assq 'foo (frame-parameters f2))
-     @result{} (foo . nobody)
