24 ;;; Commentary:
26 ;; This is loaded into a bare Emacs to make a dumpable one.
28 ;; If you add/remove Lisp files to be loaded here, consider the
29 ;; following issues:
31 ;; i) Any file loaded on all platforms should appear in $lisp
32 ;; and $shortlisp in src/Makefile.in. Use the .el or .elc version as
33 ;; appropriate.
35 ;; ii) Any file that is only loaded on some platforms should appear
36 ;; in the version of $lisp in the generated Makefile on that platform.
37 ;; At the present time, this is achieved by use of #ifdefs.
38 ;; It should also appear in $SOME_MACHINE_LISP on all platforms.
40 ;; The above steps ensure both that the Lisp files are compiled (if
41 ;; necessary) before the emacs executable is dumped, and that they are
42 ;; passed to make-docfile. (Any that are not processed for DOC will
43 ;; not have doc strings in the dumped Emacs.) Because of this:
45 ;; iii) If the file is loaded uncompiled, it should (where possible)
46 ;; obey the doc-string conventions expected by make-docfile.
48 ;;; Code:
50 ;; Add subdirectories to the load-path for files that might get
51 ;; autoloaded when bootstrapping.
