This script compare an iso2709 file and the MARC parameters
It will show the marc fields/subfields used in Koha, and that are not anywhere in the iso2709 file and which fields/subfields that are used in the iso2709 file and not in Koha.
to solve this, just modify Koha parameters (change TAB)
parameters :
\tv : this version/help screen
\tfile /path/to/file/to/dump : the file to dump
\tw : warning and strict off. If your dump fail, try -w option. It it works, then, the file is iso2709, but a buggy one !
\tc : the frameworkcode. If omitted, set to ""
SAMPLE : ./compare_iso_and_marc_parameters.pl -file /home/paul/koha.dev/local/npl -n 1
