+=head1 NAME
+
+cleandsproduct.pl - cleans up a data store product
+
+=head1 SYNOPSIS
+
+cleandsproduct.pl --product <product name> [--last-fileset <filesetid>] [--no-rm] [--retention-days <days>] [--use-configured-publish-retention]
+
+=head1 DESCRIPTION
+
+Uses L<dsproductls> to get a listing of all of the filesets in a data store product, then the program L<dsreg> is used to delete
+the filesets from the data store directory and their representation in the database.
+
+By default, all filesets are deleted. Certain options may be used to stop the cleanup after a given fileset 
+or once all remaining filesets are newer than some time.
+
+=head1 OPTIONS
