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