Drupal 7: Add a custom link in admin menu

Here is some code to be used in a custom module in Drupal 7 in order to create a custom link in the admin menu. This item will show up in the Configuration section and it is particularly useful with the administration menu module.


 'My Item Parent Name',
      'description' => 'My Description',
      'position' => 'left',
      'weight' => -100,
      'page callback' => 'system_admin_menu_block_page',
      'access arguments' => array('administer site configuration'),
      'file' => 'system.admin.inc',
      'file path' => drupal_get_path('module', 'system'),
  );
  //We need at least one child item, otherwise parent will not show up
  $items['admin/config/parent-name/child-name'] = array(
      'title' => 'My Item Child Name',
      'description' => 'My Description',
      'page callback' => 'drupal_goto',
      'page arguments' => array('my-path'),
      'access arguments' => array('administer site configuration'),
  );
  return $items;
}
