### 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

test -z "$EMACS" && EMACS="./src/xemacs"
echo " (using $EMACS)"

export EMACS

# Account for various system automounter configurations
if test -d "/net"; then
  if test -d "/tmp_mnt/net"; then tdir="/tmp_mnt/net"; else tdir="/tmp_mnt"; fi
  EMACS_DIR=`echo "$EMACS_DIR" | \
   sed -e "s|^${tdir}/|/net/|" -e "s|^/a/|/net/|" -e "s|^/amd/|/net/|"`
