 * software.
 *
 * Image toolkits are discovered using the Plugin system using
 * \Drupal\Core\ImageToolkit\ImageToolkitManager. The toolkit must then be
 * enabled using the admin/config/media/image-toolkit form.
 *
 * Only one toolkit may be selected at a time. If a module author wishes to call

 * \Drupal\Core\ImageToolkit\ImageToolkitManager::getAvailableToolkits(), and
