* )
* 2. The "automatic" way. For inserting multiple at a time based on the
* specs in the info file for the module(s). For this to work the
* modules must be correctly setup in the info file.
* An example follows (this would insert the settings, log, and flag
* modes from the includes/acp/info/acp_asacp.php file):
* array(
* 'module_basename' => 'asacp',
* 'modes' => array('settings', 'log', 'flag'),
* )
