87 $0: Remove unused authority records
89 This script removes authority records that do not have any biblio
90 records attached to them.
92 If the --aut option is supplied, only authority records of that
93 particular type will be checked for usage. --aut can be repeated.
95 If --aut is not supplied, all authority records will be checked.
97 Use --test to perform a test run. This script does not ask the
98 operator to confirm the deletion of each authority record.
101 --aut|authtypecode TYPE the list of authtypes to check
102 --test or -t test mode, don't delete really, just count
103 --help or -h show this message.
