+2003-07-16 Rodrigo Moya <rodrigo@ximian.com>
+
+ * gui/gnome-cal.[ch] (gnome_calendar_purge): new function,
+ which uses a CalQuery to retrieve the objects older than a given date.
+ (check_instance_cb): callback for cal_recur_generate_instances.
+ (purging_obj_updated_cb): call check_instance_cb on each recurrence
+ to double-check the event can be deleted.
+ (purging_query_done_cb, purging_eval_error_cb): needed callbacks to
+ finish the query.
+ (gnome_calendar_destroy): free new members.
+
+ * gui/calendar-commands.c (purge_cmd): added implementation for the
+ 'Purge' menu item.
