# Revision 1.47 2007/06/06 13:08:35 tipaul
# bugfixes (various), handling utf-8 without guessencoding (as suggested by joshua, fixing some zebra config files -for french but should be interesting for other languages-
#
# Revision 1.46 2007/05/10 14:45:15 tipaul
# Koha NoZebra :
# - support for authorities
# - some bugfixes in ordering and "CCL" parsing
# - support for authorities <=> biblios walking
#
# Seems I can do what I want now, so I consider its done, except for bugfixes that will be needed i m sure !
#
# Revision 1.45 2007/04/06 14:48:45 hdl
# Code Cleaning : AuthoritiesMARC.
#
# Revision 1.44 2007/04/05 12:17:55 btoumi
# add "sort by" with heading-entity in authorities search
#
# Revision 1.43 2007/03/30 11:59:16 tipaul
# some cleaning (minor, the main one will come later) : removing some unused subs
#
# Revision 1.42 2007/03/29 16:45:53 tipaul
# Code cleaning of Biblio.pm (continued)
#
# All subs have be cleaned :
# - removed useless
# - merged some
# - reordering Biblio.pm completly
# - using only naming conventions
#
# Seems to have broken nothing, but it still has to be heavily tested.
# Note that Biblio.pm is now much more efficient than previously & probably more reliable as well.
#
# Revision 1.41 2007/03/29 13:30:31 tipaul
# 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 TransformKohaToMarc+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)
#
