  33 This script rebuilds the non-MARC DB from the MARC values.
  34 You can/must use it when you change your mapping.
  35
  36 Example: you decide to map biblio.title to 200\$a (it was previously mapped to 610\$a).
  37 Run this script or you will have strange results in OPAC !

  39 Syntax:
  40 \t./batchRebuildBiblioTables.pl -h (or without arguments => shows this screen)
  41 \t./batchRebuildBiblioTables.pl -c (c like confirm => rebuild non marc DB (may be long)
  42 \t-t => test only, change nothing in DB
