tipaul a481fad4b7 Code cleaning :
== Biblio.pm cleaning (useless) ==
* some sub declaration dropped
* removed modbiblio sub
* removed moditem sub
* removed newitems. It was used only in finishrecieve. Replaced by a Koha2Marc+AddItem, that is better.
* removed MARCkoha2marcItem
* removed MARCdelsubfield declaration
* removed MARCkoha2marcBiblio

== Biblio.pm cleaning (naming conventions) ==
* MARCgettagslib renamed to GetMarcStructure
* MARCgetitems renamed to GetMarcItem
* MARCfind_frameworkcode renamed to GetFrameworkCode
* MARCmarc2koha renamed to TransformMarcToKoha
* MARChtml2marc renamed to TransformHtmlToMarc
* MARChtml2xml renamed to TranformeHtmlToXml
* zebraop renamed to ModZebra

== MARC=OFF ==
* removing MARC=OFF related scripts (in cataloguing directory)
* removed checkitems (function related to MARC=off feature, that is completly broken in head. If someone want to reintroduce it, hard work coming...)
* removed getitemsbybiblioitem (used only by MARC=OFF scripts, that is removed as well)

parameters :
\th : this version/help screen
\tfile /path/to/file/to/dump : the file to dump
\tv : verbose mode. 1 means "some infos", 2 means "MARC dumping"
\tn : the number of records to import. If missing, all the file is imported
\tcommit : the number of records to wait before performing a 'commit' operation
\tt : test mode : parses the file, saying what he would do, but doing nothing.
\tc : the characteristic MARC flavour. At the moment, only MARC21 and UNIMARC
\tsupported. MARC21 by default.
\td : delete EVERYTHING related to biblio in koha-DB before import :tables :
\t\tbiblio, \t\tbiblioitems, \t\tsubjects,\titems
\tmarc_biblio,
\t\tmarc_subfield_table, \tmarc_word, \t\tmarc_blob_subfield
IMPORTANT : don't use this script before you've entered and checked your MARC parameters tables twice (or more!).
Otherwise, the import won't work correctly and you will get invalid data.
