This script initializes DB tables managed by Codebase classes. If database schema is changed a log message will display.

Usage: <?php echo $cli_executed; ?> [OPTIONS] CLASSNAME

OPTIONS

    -c FILE Path to include custom site _config.inc.php file.
    -f      Force recreation of tables, if they already exist. WARNING: this will delete existing records.
    -h      Show this help message.

CLASSNAME is one of:

    all         Special case: create tables for all classes.
    acl         Create tables for ACL
    auth        Create tables for Auth_SQL
    lock        Create tables for Lock
    prefs       Create tables for Prefs
    version     Create tables for Version
    session     Create tables for DBSessionHandler
