  29 This script rebuilds the non-MARC DB from the MARC values.
  30 You can/must use it when you change your mapping.
  31 For example : you decide to map biblio.title to 200$a (it was previously mapped to 610$a) : run this script or you will have strange
  32 results in OPAC !
  33 syntax :
  34 \t./rebuildnonmarc.pl -h (or without arguments => shows this screen)
  35 \t./rebuildnonmarc.pl -c (c like confirm => rebuild non marc DB (may be long)
  36 \t-t => test only, change nothing in DB
