org.dspace.browse.IndexBrowse
Tool to create Browse indexes. This class is used from the command line to create and destroy the browse indices from configuration, and also from within the application to add and remove content from those tables. To see a full definition of the usage of this class just run it without any arguments, and you will get the help message. @author Richard Jones
