+MULTIPLE PROCESS SUPPORT
+===========================================================================
+To run multiple Lisp processes, you start the first up
+with \\[inferior-lisp]. It will be in a buffer named `*inferior-lisp*'.
+Rename this buffer with \\[rename-buffer]. You may now start up a new
+process with another \\[inferior-lisp]. It will be in a new buffer,
+named `*inferior-lisp*'. You can switch between the different process
+buffers with \\[switch-to-buffer].
+
+Commands that send text from source buffers to Lisp processes --
+like `lisp-eval-defun' or `lisp-show-arglist' -- have to choose a process
+to send to, when you have more than one Lisp process around. This
+is determined by the global variable `inferior-lisp-buffer'. Suppose you
+have three inferior Lisps running:
+ Buffer Process
+ foo inferior-lisp
+ bar inferior-lisp<2>
+ *inferior-lisp* inferior-lisp<3>
+If you do a \\[lisp-eval-defun] command on some Lisp source code,
+what process do you send it to?
+
+- If you're in a process buffer (foo, bar, or *inferior-lisp*),
+ you send it to that process.
+- If you're in some other buffer (e.g., a source file), you
+ send it to the process attached to buffer `inferior-lisp-buffer'.
+This process selection is performed by function `inferior-lisp-proc'.
+
+Whenever \\[inferior-lisp] fires up a new process, it resets
+`inferior-lisp-buffer' to be the new process's buffer. If you only run
+one process, this does the right thing. If you run multiple
+processes, you can change `inferior-lisp-buffer' to another process
+buffer with \\[set-variable].")

-MULTIPLE PROCESS SUPPORT
-===========================================================================
-Cmulisp.el supports, in a fairly simple fashion, running multiple Lisp
-processes. To run multiple Lisp processes, you start the first up with
-\\[cmulisp]. It will be in a buffer named *cmulisp*. Rename this buffer
-with \\[rename-buffer]. You may now start up a new process with another
-\\[cmulisp]. It will be in a new buffer, named *cmulisp*. You can
-switch between the different process buffers with \\[switch-to-buffer].
-
-Commands that send text from source buffers to Lisp processes --
-like lisp-eval-defun or lisp-show-arglist -- have to choose a process
-to send to, when you have more than one Lisp process around. This
-is determined by the global variable cmulisp-buffer. Suppose you
-have three inferior lisps running:
- Buffer Process
- foo cmulisp
- bar cmulisp<2>
- *cmulisp* cmulisp<3>
-If you do a \\[lisp-eval-defun-and-go] command on some Lisp source code,
-what process do you send it to?
-
-- If you're in a process buffer (foo, bar, or *cmulisp*),
- you send it to that process.
-- If you're in some other buffer (e.g., a source file), you
- send it to the process attached to buffer cmulisp-buffer.
-This process selection is performed by function cmulisp-proc.
-
-Whenever \\[cmulisp] fires up a new process, it resets cmulisp-buffer
-to be the new process's buffer. If you only run one process, this will
-do the right thing. If you run multiple processes, you can change
-cmulisp-buffer to another process buffer with \\[set-variable].
-
-More sophisticated approaches are, of course, possible. If you find youself
-needing to switch back and forth between multiple processes frequently,
-you may wish to consider ilisp.el, a larger, more sophisticated package
-for running inferior Lisp processes. The approach taken here is for a
-minimal, simple implementation. Feel free to extend it.")

;;; ===========================================================================
+;;; 7/21/92 Jim Blandy
+;;; - Changed all uses of the cmulisp name or prefix to inferior-lisp;
+;;; this is now the official inferior lisp package. Use the global
+;;; ChangeLog from now on.
;;; 5/24/90 Olin
;;; - Split cmulisp and cmushell modes into separate files.
;;; Not only is this a good idea, it's apparently the way it'll be rel 19.
;;; 3/12/90 Olin
;;; - lisp-load-file and lisp-compile-file no longer switch-to-lisp.
;;; Tale suggested this.
+;;; - Reversed this decision 7/15/91. You need the visual feedback.
+;;;
+;;; 7/25/91 Olin
+;;; Changed all keybindings of the form C-c <letter>. These are
+;;; supposed to be reserved for the user to bind. This affected
+;;; mainly the compile/eval-defun/region[-and-go] commands.
+;;; This was painful, but necessary to adhere to the gnumacs standard.
+;;; For some backwards compatibility, see the
+;;; cmulisp-install-letter-bindings
+;;; function.
+;;;
+;;; 8/2/91 Olin
+;;; - The lisp-compile/eval-defun/region commands now take a prefix arg,
+;;; which means switch-to-lisp after sending the text to the Lisp process.
+;;; This obsoletes all the -and-go commands. The -and-go commands are
+;;; kept around for historical reasons, and because the user can bind
+;;; them to key sequences shorter than C-u C-c C-<letter>.
+;;; - If M-x cmulisp is invoked with a prefix arg, it allows you to
+;;; edit the command line.
