# Revision 1.26 2006/05/20 14:32:54 tgarip1957
# If an authority is modified biblios related to this authority were not updated but a list of modified authorities was written to disk. Now by defult they get modified as well unless a system preference 'dontmerge' is defined. dontmerge=1 will keep the previous behaviour.
#
# Authority zebra server may have different shadow settings. Support is added
#
# Revision 1.25 2006/05/19 18:09:39 tgarip1957
# All support for auth_subfield_tables is removed. All search is now with zebra authorities. New authority structure allows multiple linking of authorities of differnet types to one another.
# Authority tables are modified to be compatible with new MARC frameworks. This change is part of Authority Linking & Zebra authorities. Requires change in Mysql database. It will break head unless all changes regarding this is implemented. This warning will take place on all commits regarding this
#
# Revision 1.9.2.6 2005/06/07 10:02:00 tipaul
# porting dictionnary search from head to 2.2. there is now a ... facing titles, author & subject, to search in biblio & authorities existing values.
#
# Revision 1.9.2.5 2005/05/31 14:50:46 tipaul
# fix for authority merging. There was a bug on official installs
#
# Revision 1.9.2.4 2005/05/30 11:24:15 tipaul
# fixing a bug : when a field was repeated, the last field was also repeated. (Was due to the "empty" field in html between fields : to separate fields, in html, an empty field is automatically added. in AUTHhtml2marc, this empty field was not discarded correctly)
#
# Revision 1.9.2.3 2005/04/28 08:45:33 tipaul
# porting FindDuplicate feature for authorities from HEAD to rel_2_2, works correctly now.
#
# Revision 1.9.2.2 2005/02/28 14:03:13 tipaul
# * adding search on "main entry" (ie $a subfield) on a given authority (the "search everywhere" field is still here).
# * adding a select box to requet "contain" or "begin with" search.
# * fixing some bug in authority search (related to "main entry" search)
#
# Revision 1.9.2.1 2005/02/24 13:12:13 tipaul
# saving authority modif in a text file. This will be used soon with another script (in crontab). The script in crontab will retrieve every authorityid in the directory localfile/authorities and modify every biblio using this authority. Those modifs may be long. So they can't be done through http, because we may encounter a webserver timeout, and kill the process before end of the job.
# So, it will be done through a cron job.
# (/me agree we need some doc for command line scripts)
#
# Revision 1.9 2004/12/23 09:48:11 tipaul
# Minor changes in summary "exploding" (the 3 digits AFTER the subfield were not on the right place).
#
# Revision 1.8 2004/11/05 10:11:39 tipaul
# export auth_count_usage (bugfix)
#
# Revision 1.7 2004/09/23 16:13:00 tipaul

#
# Revision 1.6 2004/08/18 16:00:24 tipaul

# Revision 1.5 2004/07/05 13:37:22 doxulting
# First step for working authorities
#
# Revision 1.4 2004/06/22 11:35:37 tipaul
# removing % at the beginning of a string to avoid loooonnnngggg searchs
