  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.
  48

  50

  52 ;; autoloaded when bootstrapping.
