# Revision 1.39 2007/03/16 01:25:08 kados
# Using my precrash CVS copy I did the following:

# 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.
