<?php
/* This script allows importing a group .db3 file from a backup
 * or another rslight site.
 * 
 * Place the article database file group.name-articles.db3 in 
 * your spool directory, and change user/group to your web user.
 * Run this script as your web user from your $webdir/spoolnews dir:
 * php $config_dir/scripts/import.php group.name
 *
 * To import/upgrade all group.db3 files, do not list group.name 
 * after the above command.
 *
 * This will create the overview files necessary to import the group
 * into your site.
 * Next: Add the group to the groups.txt file of the section you wish
 * it to appear:
 * $config_dir/<section>/groups.txt
