tipaul 4cf30123a4 1st commit to go to zebra. 
don't update your cvs if you want to have a working head...

this commit contains :
* updater/updatedatabase : get rid with marc_* tables, but DON'T remove them. As a lot of things uses them, it would not be a good idea for instance to drop them. If you really want to play, you can rename them to test head without them but being still able to reintroduce them...
* Biblio.pm : modify MARCgetbiblio to find the raw marc record in biblioitems.marc field, not from marc_subfield_table, modify MARCfindframeworkcode to find frameworkcode in biblio.frameworkcode, modify some other subs to use biblio.biblionumber & get rid of bibid.
* other files : get rid of bibid and use biblionumber instead.

What is broken :
* does not do anything on zebra yet.
* if you rename marc_subfield_table, you can't search anymore.
* you can view a biblio & bibliodetails, go to MARC editor, but NOT save any modif.
* don't try to add a biblio, it would add data poorly... (don't try to delete either, it may work, but that would be a surprise ;-) )

IMPORTANT NOTE : you need MARC::XML package (http://search.cpan.org/~esummers/MARC-XML-0.7/lib/MARC/File/XML.pm), that requires a recent version of MARC::Record
Updatedatabase stores the iso2709 data in biblioitems.marc field & an xml version in biblioitems.marcxml Not sure we will keep it when releasing the stable version, but I think it's a good idea to have something readable in sql, at least for development stage.

# Revision 1.119 2005/08/04 16:07:58 tipaul
# Synch really broke this script...
#
# Revision 1.118 2005/08/04 16:02:55 tipaul
# oops... error in synch between 2.2 and head
#
# Revision 1.117 2005/08/04 14:24:39 tipaul
# synch'ing 2.2 and head
#
# Revision 1.116 2005/08/04 08:55:54 tipaul
# Letters / alert system, continuing...
#
# * adding a package Letters.pm, that manages Letters & alerts.
# * adding feature : it's now possible to define a "letter" for any subscription created. If a letter is defined, users in OPAC can put an alert on the subscription. When an issue is marked "arrived", all users in the alert will recieve a mail (as defined in the "letter"). This last part (= send the mail) is not yet developped. (Should be done this week)
# * adding feature : it's now possible to "put to an alert" in OPAC, for any serial subscription. The alert is stored in a new table, called alert. An alert can be put only if the librarian has activated them in subscription (and they activate it just by choosing a "letter" to sent to borrowers on new issues)
# * adding feature : librarian can see in borrower detail which alerts they have put, and a user can see in opac-detail which alert they have put too.
#
# Note that the system should be generic enough to manage any type of alert.
# I plan to extend it soon to virtual shelves : a borrower will be able to put an alert on a virtual shelf, to be warned when something is changed in the virtual shelf (mail being sent once a day by cron, or manually by the shelf owner. Anyway, a mail won't be sent on every change, users would be spammed by Koha ;-) )
#
# Revision 1.115 2005/08/02 16:15:34 tipaul
# adding 2 fields to letter system :
# * module (acquisition, catalogue...) : it will be usefull to show the librarian only letters he may be interested by.
# * title, that will be used as mail subject.
#
# Revision 1.114 2005/07/28 15:10:13 tipaul
# Introducing new "Letters" system : Letters will be used everytime you want to sent something to someone (through mail or paper). For example, sending a mail for overdues use letter that you can put as parameters. Sending a mail to a borrower when a suggestion is validated uses a letter too.
# the letter table contains 3 fields :
# * code => the code of the letter
# * name => the complete name of the letter
# * content => the complete text. It's a TEXT field type, so has no limits.
#
# My next goal now is to work on point 2-I "serial issue alert"
# With this feature, in serials, a user can subscribe the "issue alert". For every issue arrived/missing, a mail is sent to all subscribers of this list. The mail warns the user that the issue is arrive or missing. Will be in head.
# (see mail on koha-devel, 2005/04/07)
#
# The "serial issue alert" will be the 1st to use this letter system that probably needs some tweaking ;-)
#
# Once it will be stabilised default letters (in any languages) could be added during installer to help the library begin with this new feature.
#
# Revision 1.113 2005/07/28 08:38:41 tipaul
# For instance, the return date does not rely on the borrower expiration date. A systempref will be added in Koha, to modify return date calculation schema :
# * ReturnBeforeExpiry = yes => return date can't be after expiry date
# * ReturnBeforeExpiry = no => return date can be after expiry date
#
# Revision 1.112 2005/07/26 08:19:47 hdl
# Adding IndependantBranches System preference variable in order to manage Branch independancy.
#
# Revision 1.111 2005/07/25 15:35:38 tipaul
# we have decided that moving to Koha 3.0 requires being already in Koha 2.2.x
# So, the updatedatabase script can highly be cleaned (90% removed).
# Let's play with the new Koha DB structure now ;-)
