10 ;; This is a prototype site-load.el file.
|
|
|
11 ;; The site-load.el mechanism is provided so XEmacs installers can easily
|
|
|
12 ;; dump lisp packages with XEmacs that do not get dumped standardly.
|
|
|
13
|
|
|
14 ;; The file `site-packages' if it exists should look something like:
|
|
|
15 ;; (setq site-load-packages '(
|
|
|
16 ;; "../lisp/modes/cc-mode"
|
|
|
17 ;; "../lisp/utils/redo"
|
|
|
18 ;; "../lisp/packages/scroll-in-place"
|
|
|
19 ;; )
|
|
|
20 ;; )
|
|
|
21
|
|
|
22 ;; The first line and the last line must be exact. Each of the packages
|
|
|
23 ;; listed must be double quoted, have either an absolute path, or a relative
|
|
|
24 ;; to the build src directory path *and* be bytecompiled prior to the attempt
|
|
|
25 ;; to dump.
|
|
|
26
|
|
|
27 ;; Because this is a trial implementation and the file is shared with
|
|
|
28 ;; make-docfiles, syntax is strict and unforgiving. So sue me. It
|
|
|
29 ;; is still better than the way it used to be.
|
|
|

|
|

|
31 ;; Also note that site-packages belongs in the top level directory not the
|
|
|
32 ;; lisp directory for use with --srcdir configurations.
