/**
 * Horde Preferences toolkit.
 *
 * Usage: horde-prefs CONFIG USER (list|print|export|import) [[SCOPE] [FILE]]
 *
 * The CONFIG file needs to provide the complete configuration for the
 * preferences storage backend.
 *
 * This is an example for the file based storage backend:
 *
 * <pre>
 * <?php
 *   $conf['driver'] = 'File';
 *   $conf['params']['directory'] = '/var/www/data/horde/prefs';
 * </pre>
 *
 * The following example is the necessary setup for a SQL database:
 *
 * <pre>
 * <?php
 *   $conf['driver'] = 'Sql';
 *   $conf['params']['db'] = new Horde_Db_Adapter_Mysql(
 *     array(
 *      'persistent' => false,
 *      'username' => 'root',
 *      'password' => 'PASSWORD',
 *      'socket' => '/var/run/mysqld/mysqld.sock',
 *      'protocol' => 'unix',
 *      'database' => 'horde',
 *      'charset' => 'utf-8',
 *      'ssl' => true,
 *      'splitread' => false,
 *      'phptype' => 'mysql',
 *    )
 *  );
 * </pre>
 *
 * Configuring for the Kolab storage backend is more complex:
 *
 * <pre>
 * <?php
 *   $conf['driver'] = 'KolabImap';
 *   $factory = new Horde_Kolab_Storage_Factory(
 *       array(
 *           'driver' => 'horde',
 *           'params' => array(
 *               'host' => 'example.org',
 *               'username' => 'user@example.org',
 *               'password' => 'test',
 *               'port'     => 993,
 *               'secure'   => true
 *           ),
 *           'queryset' => array(
 *               'list' => array('queryset' => 'horde'),
 *               'data' => array('queryset' => 'horde'),
 *           ),
 *           'cache' => new Horde_Cache(new Horde_Cache_Storage_Mock()),
 *           //'logger' => new Horde_Log_Logger(new Horde_Log_Handler_Stream(STDOUT)),
 *       )
 *   );
 *   $conf['params']['kolab'] = $factory->create();
 * </pre>
