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

  40 \t./batchRebuildBiblioTables.pl -c (c like confirm => rebuild non marc DB (may be long)
  41 \t-t => test only, change nothing in DB
