| 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. It |
| 42 | ;; should also be added to the uncompiled[] list in make-docfile.c. |
| 43 | |
| 44 | ;;; Code: |
| 45 | |
| 46 | ;; Add subdirectories to the load-path for files that might get |
| 47 | ;; autoloaded when bootstrapping. |
