This script rebuilds the non-MARC DB from the MARC values.
You can/must use it when you change your mapping.
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
results in OPAC !
syntax :
\t./rebuildnonmarc.pl -h (or without arguments => shows this screen)
\t./rebuildnonmarc.pl -c (c like confirm => rebuild non marc DB (may be long)
\t-t => test only, change nothing in DB
