1245 # * some sub declaration dropped
1246 # * removed modbiblio sub
1247 # * removed moditem sub
1248 # * removed newitems. It was used only in finishrecieve. Replaced by a TransformKohaToMarc+AddItem, that is better.

1251 # * removed MARCkoha2marcBiblio
1252 #

1265 # * removed getitemsbybiblioitem (used only by MARC=OFF scripts, that is removed as well)
