908 # Revision 1.9.2.2 2005/02/28 14:03:13 tipaul
909 # * adding search on "main entry" (ie $a subfield) on a given authority (the "search everywhere" field is still here).
910 # * adding a select box to requet "contain" or "begin with" search.

913 # Revision 1.9.2.1 2005/02/24 13:12:13 tipaul
914 # 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.
915 # So, it will be done through a cron job.
916 # (/me agree we need some doc for command line scripts)
