109 $0: Remove unused authority records
111 This script removes authority records that do not have any biblio
112 records attached to them.
114 If the --aut option is supplied, only authority records of that
115 particular type will be checked for usage. --aut can be repeated.
117 If --aut is not supplied, all authority records will be checked.
119 Use --test to perform a test run. This script does not ask the
120 operator to confirm the deletion of each authority record.
123 --aut|authtypecode TYPE the list of authtypes to check
124 --test or -t test mode, don't delete really, just count
125 --help or -h show this message.
