and is not in the repository any more.

 -q: be quiet; only give error messages, not status messages.
 -A: only update autotools files, copying into specified dir.
 -H: also update ChangeLog.${changelog_n}
--I: also update info/dir.
 -L: also update ldefs-boot.el.
 -C: start from a clean state.  Slower, but more correct.
