+;;; site-load.el --- Template file for site-wide XEmacs customization
+;; Copyright (C) 1997 Free Software Foundation, Inc.
+
+;; Author: Steven L. Baur <steve@xemacs.org>
+;; Keywords: internal
+
+;; This file is part of XEmacs.
+
+;;; Commentary:
+
+;; This is a prototype site-load.el file.
+;; The site-load.el mechanism is provided so XEmacs installers can easily
+;; dump lisp packages with XEmacs that do not get dumped standardly.
+
+;; The file `site-packages' if it exists should look something like:
+;; (setq site-load-packages '(
+;; "../lisp/modes/cc-mode.elc"
+;; "../lisp/utils/redo.elc"
+;; "../lisp/packages/scroll-in-place.elc"
+;; )
+;; )
+
+;; The first line and the last line must be exact.  Each of the packages
+;; listed must be double quoted, have either an absolute path, or a relative
+;; to the build src directory path *and* be bytecompiled prior to the attempt
+;; to dump.  They also must explicitly have the .elc extension.
+
+;; Because this is a trial implementation and the file is shared with
+;; make-docfiles, syntax is strict and unforgiving.  So sue me.  It
+;; is still better than the way it used to be.
+
+;; Also note that site-packages belongs in the top level directory not the
+;; lisp directory for use with --srcdir configurations.
+
+;;; Code:
+(defvar site-load-package-file "../site-packages"
+  "File name containing the list of extra packages to dump with XEmacs.")
+(defvar site-load-packages nil
+  "A list of .elc files that should be dumped with XEmacs.
+This variable should be set by `site-load-package-file'.")
+
+;; Load site specific packages for dumping with the XEmacs binary.
+(when (file-exists-p site-load-package-file) 
+  (let ((file))
+    (load site-load-package-file t t t)
+    ;; The `pureload' macro is provided as a clue that a package is
+    ;; being loaded in preparation of being dumped into XEmacs.
+    (defmacro pureload (file)
+      (list 'prog1 (list 'load file) '(garbage-collect)))
+    (message "Loading site-wide packages for dumping...")
+    (while site-load-packages
+      (setq file (car site-load-packages))
+      (pureload file)
+      (setq site-load-packages (cdr site-load-packages)))
+    (message "Loading site-wide packages for dumping...done")
+    (fmakunbound 'pureload)))
+
+;; This file is intended for end user additions.
+;; Put other initialization here, like setting of language-environment, etc.
+;; Perhaps this should really be in the site-init.el.

+;;; site-load.el ends here
