  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 any platform should appear in $lisp in src/lisp.mk.
  33 ;; Use the .el or .elc version as appropriate.
  34
  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:
  39
  40 ;; ii) If the file is loaded uncompiled, it should (where possible)
  41 ;; obey the doc-string conventions expected by make-docfile.
  42
  43 ;;; Code:
  44
  45 ;; Add subdirectories to the load-path for files that might get
  46 ;; autoloaded when bootstrapping.
  47 ;; This is because PATH_DUMPLOADSEARCH is just "../lisp".
  48 ;; Note that we reset load-path below just before dumping,
  49 ;; since lread.c:init_lread checks for changes to load-path
  50 ;; in deciding whether to modify it.
