;;; Commentary:
;; This is loaded into a bare Emacs to make a dumpable one.
;; If you add/remove Lisp files to be loaded here, consider the
;; following issues:
;; i) Any file loaded on any platform should appear in $lisp in src/lisp.mk.
;; Use the .el or .elc version as appropriate.
;; This ensures both that the Lisp files are compiled (if necessary)
;; before the emacs executable is dumped, and that they are passed to
;; make-docfile. (Any that are not processed for DOC will not have
;; doc strings in the dumped Emacs.) Because of this:
;; ii) If the file is loaded uncompiled, it should (where possible)
;; obey the doc-string conventions expected by make-docfile. It
;; should also be added to the uncompiled[] list in make-docfile.c.
;;; Code:
;; Add subdirectories to the load-path for files that might get
;; autoloaded when bootstrapping.
;; This is because PATH_DUMPLOADSEARCH is just "../lisp".
;; Note that we reset load-path below just before dumping,
;; since lread.c:init_lread checks for changes to load-path
;; in deciding whether to modify it.
