;; Cscheme-specific; you must use cmuscheme.el. Interested parties are
;; invited to port xscheme functionality on top of comint mode...
+;;; CHANGE LOG
+;;; ===========================================================================
+;;; 8/88 Olin
+;;; Created.
+;;;
+;;; 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
+;;; - scheme-load-file and scheme-compile-file no longer switch-to-scheme.
+;;; Tale suggested this.
