-### Commentary:
-
-## This is the list of all Lisp files that might be loaded into the
-## dumped Emacs.  Some of them are not loaded on all platforms, but
-## the DOC file on every platform uses them (because the DOC file is
-## supposed to be platform-independent).
-## It is arranged like this because it is easier to generate it
-## semi-mechanically from loadup.el this way.
-## Eg something like:
-##   sed -e 's/"[ )].*//' -n -e '/(load "/ s/.*load "//p' loadup.el | \
-##   grep -vE 'site-|ldefs-boot'
-## minus any duplicates.
-## Note that you can generally just add a ".elc" extension to every file
-## that does not have an explicit .el extension, but beware of any
-## no-byte-compile ones.
-
-## Confusingly, international/cp51932 and international/eucjp-ms are
-## unconditionally loaded from language/japanese, instead of being
-## loaded directly from loadup.el; FIXME.
-
-## Note that this list should not include lisp files which might not
-## be present, like site-load.el and site-init.el; this makefile
-## expects them all to be either present or buildable.
-
-## Place loaddefs.el first, so it gets generated first, since it is on
-## the critical path (relevant in parallel compilations).
-
-### Code:
-
-## NB: This list is parsed by sed in the main src/Makefile.
-## Do not change the formatting.
