/* This script allows importing a group .db3 file from a backup
|
|
* or another rslight site, and other features.
|
|
*
|
|
* Use -help to see other features.
|
|
*
|
|
* To import a group db3 file:
|
|
* 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
|
