 876 #
 877 # Revision 1.9.2.4  2005/05/30 11:24:15  tipaul
 878 # 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)

 884 # * adding search on "main entry" (ie $a subfield) on a given authority (the "search everywhere" field is still here).
 885 # * adding a select box to requet "contain" or "begin with" search.
 886 # * fixing some bug in authority search (related to "main entry" search)

 889 # 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.
 890 # So, it will be done through a cron job.
