91 $0: Remove unused authority records
93 This script removes authority records that do not have any biblio
94 records attached to them.
96 If the --aut option is supplied, only authority records of that
97 particular type will be checked for usage. --aut can be repeated.
99 If --aut is not supplied, all authority records will be checked.
101 Use --test to perform a test run. This script does not ask the
102 operator to confirm the deletion of each authority record.
105 --aut|authtypecode TYPE the list of authtypes to check
106 --test or -t test mode, don't delete really, just count
107 --help or -h show this message.
