# Prepare a bootstrap in the lisp subdirectory.

# Build loaddefs.el to make sure it's up-to-date.  If it's not, that
# might lead to errors during the bootstrap because something fails to
# autoload as expected.  If there is no emacs binary, then we can't
# build autoloads yet.  In that case we have to use ldefs-boot.el.
# Bootstrap should always work with ldefs-boot.el.  Therefore,
# whenever a new autoload cookie gets added that is necessary during
# bootstrapping, ldefs-boot.el should be updated by overwriting it with
# an up-to-date copy of loaddefs.el that is uncorrupted by
# local changes.  (Because loaddefs.el is an automatically generated
# file, we don't want to store it in the source repository).
