25 ;;; Commentary:
27 ;; This is loaded into a bare Emacs to make a dumpable one.
29 ;; If you add/remove Lisp files to be loaded here, consider the
30 ;; following issues:
32 ;; i) Any file loaded on any platform should appear in $lisp in src/lisp.mk.
33 ;; Use the .el or .elc version as appropriate.
35 ;; This ensures both that the Lisp files are compiled (if necessary)
36 ;; before the emacs executable is dumped, and that they are passed to
37 ;; make-docfile. (Any that are not processed for DOC will not have
38 ;; doc strings in the dumped Emacs.) Because of this:
40 ;; ii) If the file is loaded uncompiled, it should (where possible)
41 ;; obey the doc-string conventions expected by make-docfile. It
42 ;; should also be added to the uncompiled[] list in make-docfile.c.
44 ;;; Code:
46 ;; Add subdirectories to the load-path for files that might get
47 ;; autoloaded when bootstrapping.
48 ;; This is because PATH_DUMPLOADSEARCH is just "../lisp".
