### Commentary:

# This is much simpler than update-autoloads.el.  All we need to do is
# compute a list of directories we want to use, and feed it to
# Custom-make-dependencies.  End of story.

### Code:

set -eu

# get to the right directory
test ! -d ./lisp -a -d ../lisp && cd ..
if test ! -d ./lisp ; then
	echo $0: neither ./lisp/ nor ../lisp/ exist
	exit 1
fi
