   lonsearchcat
   
   =head1 SYNOPSIS
   
   Search interface to LON-CAPAs digital library
   
   =head1 DESCRIPTION
   
   This module enables searching for a distributed browseable catalog.
   
   This is part of the LearningOnline Network with CAPA project
   described at http://www.lon-capa.org.
   
   lonsearchcat presents the user with an interface to search the LON-CAPA
   digital library.  lonsearchcat also initiates the execution of a search
   by sending the search parameters to LON-CAPA servers.  The progress of 
   search (on a server basis) is displayed to the user in a seperate window.
