29;; If you add/remove Lisp files to be loaded here, consider the
30;; following issues:
31
b9704ad9
GM
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.

GM
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:
607b8307 39
4a720484 40;; ii) If the file is loaded uncompiled, it should (where possible)
2068905b
EZ
41;; obey the doc-string conventions expected by make-docfile. It
42;; should also be added to the uncompiled[] list in make-docfile.c.
