;;; Commentary:
-;;; Hacked from tea.el by Olin Shivers (shivers@cs.cmu.edu). 8/88
-
-;;; This file defines a a lisp-in-a-buffer package (inferior-lisp
-;;; mode) built on top of comint mode. This version is more
-;;; featureful, robust, and uniform than the Emacs 18 version. The
-;;; key bindings are also more compatible with the bindings of Hemlock
-;;; and Zwei (the Lisp Machine emacs).
-
-;;; Since this mode is built on top of the general command-interpreter-in-
-;;; a-buffer mode (comint mode), it shares a common base functionality,
-;;; and a common set of bindings, with all modes derived from comint mode.
-;;; This makes these modes easier to use.
-
-;;; For documentation on the functionality provided by comint mode, and
-;;; the hooks available for customising it, see the file comint.el.
-;;; For further information on inferior-lisp mode, see the comments below.
-
-;;; Needs fixin:
-;;; The load-file/compile-file default mechanism could be smarter -- it
-;;; doesn't know about the relationship between filename extensions and
-;;; whether the file is source or executable. If you compile foo.lisp
-;;; with compile-file, then the next load-file should use foo.bin for
-;;; the default, not foo.lisp. This is tricky to do right, particularly
-;;; because the extension for executable files varies so much (.o, .bin,
-;;; .lbin, .mo, .vo, .ao, ...).
-;;;
-;;; It would be nice if inferior-lisp (and inferior scheme, T, ...) modes
-;;; had a verbose minor mode wherein sending or compiling defuns, etc.
-;;; would be reflected in the transcript with suitable comments, e.g.
-;;; ";;; redefining fact". Several ways to do this. Which is right?
-;;;
-;;; When sending text from a source file to a subprocess, the process-mark can
-;;; move off the window, so you can lose sight of the process interactions.
-;;; Maybe I should ensure the process mark is in the window when I send
-;;; text to the process? Switch selectable?

-;;; c-c c-a lisp-show-arglist Query Lisp for function's arglist.
-;;; c-c c-f lisp-show-function-documentation Query Lisp for a function's doc.
-;;; c-c c-v lisp-show-variable-documentation Query Lisp for a variable's doc.
-
-;;; inferior-lisp Fires up the Lisp process.

+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
-===========================================================================
-Inf-lisp.el supports, in a fairly simple fashion, running multiple
-Lisp processes. 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 will do the right thing. If you run multiple
-processes, you can change inferior-lisp-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.")
