-;;; lots and lots of special purpose code to read these control sequences, and
-;;; so is very tightly integrated with the cscheme process. The cscheme
-;;; interrupt handler and debugger read single character commands in cbreak
-;;; mode; when this happens, xscheme.el switches to special keymaps that bind
-;;; the single letter command keys to emacs functions that directly send the
-;;; character to the scheme process. Cmuscheme mode does *not* provide this
-;;; functionality. If you are a cscheme user, you may prefer to use the
-;;; xscheme.el/cscheme -emacs interaction.
-;;;
-;;; Here's a summary of the pros and cons, as I see them.
-;;; xscheme: Tightly integrated with inferior cscheme process! A few commands
-;;; not in cmuscheme. But. Integration is a bit of a hack. Input

-;;; cmuscheme: Not tightly integrated with inferior cscheme process. But.
-;;; Carefully integrated functionality with the entire suite of
-;;; comint-derived CMU process modes. Keybindings reminiscent of

-;;;
-;;; It's a tradeoff. Pay your money; take your choice. If you use a Scheme
-;;; that isn't Cscheme, of course, there isn't a choice. Xscheme.el is *very*

+;;; CHANGE LOG
+;;; ===========================================================================
+;;; 8/88 Olin
+;;; Created.
;;;
-;;; Unfortunately, scheme.el defines run-scheme to autoload from xscheme.el.
-;;; This will womp your declaration to autoload run-scheme from cmuscheme.el
-;;; if you haven't loaded cmuscheme in before scheme. Three fixes:
-;;; - Put the autoload on your scheme mode hook and in your .emacs toplevel:
-;;; (setq scheme-mode-hook
-;;; '((lambda () (autoload 'run-scheme "cmuscheme"
-;;; "Run an inferior Scheme" t))))
-;;; (autoload 'run-scheme "cmuscheme" "Run an inferior Scheme" t)
-;;; Now when scheme.el autoloads, it will restore the run-scheme autoload.
-;;; - Load cmuscheme.el in your .emacs: (load-library 'cmuscheme)
-;;; - Change autoload declaration in scheme.el to point to cmuscheme.el:
-;;; (autoload 'run-scheme "cmuscheme" "Run an inferior Scheme" t)
-;;; *or* just delete the autoload declaration from scheme.el altogether,
-;;; which will allow the autoload in your .emacs to have its say.
+;;; 2/15/89 Olin
+;;; Removed -emacs flag from process invocation. It's only useful for
+;;; cscheme, and makes cscheme assume it's running under xscheme.el,
+;;; which messes things up royally. A bug.
+;;;
+;;; 5/22/90 Olin
+;;; - Upgraded to use comint-send-string and comint-send-region.
+;;; - run-scheme now offers to let you edit the command line if
+;;; you invoke it with a prefix-arg. M-x scheme is redundant, and
+;;; has been removed.
+;;; - Explicit references to process "scheme" have been replaced with
+;;; (scheme-proc). This allows better handling of multiple process bufs.
+;;; - Added scheme-send-last-sexp, bound to C-x C-e. A gnu convention.
+;;; - Have not added process query facility a la cmulisp.el's lisp-show-arglist
+;;; and friends, but interested hackers might find a useful application
+;;; of this facility.
+;;;
+;;; 3/12/90 Olin
