# Code cleaning of Biblio.pm (continued)

# All subs have be cleaned :
# - removed useless

# == Biblio.pm cleaning (useless) ==
# * some sub declaration dropped

# * removed moditem sub
# * removed newitems. It was used only in finishrecieve. Replaced by a TransformKohaToMarc+AddItem, that is better.
# * removed MARCkoha2marcItem
# * removed MARCdelsubfield declaration
# * removed MARCkoha2marcBiblio
#
# == Biblio.pm cleaning (naming conventions) ==
# * MARCgettagslib renamed to GetMarcStructure

# * removed checkitems (function related to MARC=off feature, that is completly broken in head. If someone want to reintroduce it, hard work coming...)
