  66 $0: removes items from selected biblios
  67
  68 This utility is meant to be run as part of the upgrade to
  69 Koha 3.4.  It removes the 9XX fields in the bib records that
  70 store a (now) duplicate copy of the item record information.  After
  71 running this utility, a full reindexing of the bibliographic records
  72 should be run using rebuild_zebra.pl -b -r.
  73
  74 Parameters:
  75     -where                  use this to limit modifications to selected biblios
  76     --run                   perform the update
  77     --silent                run silently
  78     --help or -h            show this message
  79 _USAGE_
