; To use PSD with Scheme 48:
; - Put (setq psd-using-slib nil) in your .emacs
; - Put this file in psd-directory
; - Remove (define *psd-tab-char* (integer->char 9)) from psd's read.scm
; - Do something horrible to primitives.scm to circumvent bug in
; Scheme 48's byte code compiler... those big long lists have to be
; split up: `((x ,x) ... (y ,y) ...) =>
; (let ((foo (lambda () `((x ,x) ...)))
; (bar (lambda () `((y ,y) ...))))
; (append (foo) (bar)))
; JAR's remarks:
; - The variable *PSD-PREVIOUS-LINE* was undefined (not consequentially so)
; - It doesn't support DELAY
; - It doesn't support the => syntax in COND
; - It doesn't like (write-char c port):
; ERROR: Wrong number of arguments to primitive procedure
; write-char
; - It would be awfully nice if there were a "quit" command
; - It leaves that little "=>" arrow in my buffer (except it's not
; really there, is it?)
; - It opens the source file multiple (maybe 6) times without
; closing it (not really a problem since the GC cleans these up, but
; sort of annoying)

;;;; Imported scheme48-0.53 sources as base
;;;;
;;;; Revision 1.6 1993/10/07 08:20:14 pk
;;;; Define force-output, redefinition hurts less than getting an error
;;;; message about nonexistent procedure.
;;;;
;;;; Revision 1.5 1993/10/06 13:06:16 pk
;;;; Removed references to slib. Commented out force-output, let the user
;;;; uncomment it if needed.
;;;;
;;;; Revision 1.4 1993/09/29 08:45:11 pk
;;;; Removed reference to long and deep lists.
;;;;
;;;; Revision 1.3 1993/09/24 08:01:18 pk
;;;; Changed version number from 1.0 to 1.1.
;;;; Added loading of version.scm and announcing of version.
;;;;
;;;; Revision 1.2 1993/09/23 06:50:00 pk
;;;; Moved definition of the Scheme variable psd-directory from the psd*.scm
;;;; files to psd.el, which sends it to the Scheme process. This way, the path
;;;; to psd needs to be specified only once.

;;;; SLIB interface to load psd files.
;;;; This is the file that takes care of loading psd into the Scheme
;;;; interpreter. If you want to modify psd to work with a particular
;;;; implementation, say "foo", this is the way to do it:
;;;; 1) Make a copy of the file "psd.scm" under the name "psd-foo.scm",
;;;; and modify it to load "primitives-foo.scm" instead of
;;;; "primitives.scm". You can also do other things.
;;;;
;;;; 2) Make a copy of the file "primitives.scm" under the name
;;;; "primitives-foo.scm", and modify the definitions in it to
;;;; know about the additional primitives in your implementation
;;;;
;;;; 3) When you now set the Emacs variable scheme-program-name to
;;;; "foo" and give the commands ``M-x run-scheme'' ``M-x psd-mode'',
;;;; you have a psd system that knows about your additional
;;;; primitives.
;;; this is not portable.
