   =head1 NAME
   
   B<searchcat.pl> - put authoritative filesystem data into sql database.
   
   =head1 SYNOPSIS
   
   Ordinarily this script is to be called from a loncapa cron job
   (CVS source location: F<loncapa/loncom/cron/loncapa>; typical
   filesystem installation location: F</etc/cron.d/loncapa>).
   
   Here is the cron job entry.
   
   C<# Repopulate and refresh the metadata database used for the search catalog.>
   C<10 1 * * 7    www    /home/httpd/perl/searchcat.pl>
   
   This script only allows itself to be run as the user C<www>.
   
 # This script goes through a LON-CAPA resource  =head1 DESCRIPTION
 # directory and gathers metadata.  
 # The metadata is entered into a SQL database.  This script goes through a loncapa resource directory and gathers metadata.
   The metadata is entered into a SQL database.
   
   This script also does general database maintenance such as reformatting
   the C<loncapa:metadata> table if it is deprecated.
   
   This script evaluates dynamic metadata from the authors'
   F<nohist_resevaldata.db> database file in order to store it in MySQL, as
   well as to compress the filesize (add up all "count"-type metadata).
   
   This script is playing an increasingly important role for a loncapa
   library server.  The proper operation of this script is critical for a smooth
   and correct user experience.
