$0: Remove unused authority records
This script removes authority records that do not have any biblio
records attached to them.
If the --aut option is supplied, only authority records of that
particular type will be checked for usage. --aut can be repeated.
If --aut is not supplied, all authority records will be checked.
Use --test to perform a test run. This script does not ask the
operator to confirm the deletion of each authority record.
parameters
--aut|authtypecode TYPE the list of authtypes to check
--test or -t test mode, don't delete really, just count
--help or -h show this message.
_USAGE_
