Implements hook_system_info_alter().
By default this modules is hidden but once enabled it behaves like a normal (not hidden) module. This hook implementation changes the .info.yml data by setting the hidden status to FALSE.
function locale_test_translate_system_info_alter(&$info, $file, $type) {
if ($file->name == 'locale_test_translate') {
// Don't hide the module.
$info['hidden'] = FALSE;
}
}
