/**
 * @file
 * Support for migrate module.
 *
 * With Migrate 2.4 or later, you can use the subfield syntax to set the title
 * and attributes:
 *
 * @code
 * $this->addFieldMapping('field_my_link', 'source_url');
 * $this->addFieldMapping('field_my_link:title', 'source_title');
 * $this->addFieldMapping('field_my_link:attributes', 'source_attributes');
 * @endcode
 *
 * With earlier versions of Migrate, you must pass an arguments array:
 *
 * @code
 * $link_args = array(
 *   'title' => array('source_field' => 'source_title'),
 *   'attributes' => array('source_field' => 'source_attributes'),
 * );
 * $this->addFieldMapping('field_my_link', 'source_url')
 *      ->arguments($link_args);
 * @endcode
