/**
 * @brief The QTextTranslator class
 *
 * QTextTranslator enables real-time translation execution
 * with text format (ini) directly editable by end users
 * without using normal ts format (qm as binary).
 *
 * The Text language files used by this class can be automatically generated
 * from the usual ts file using qbs bundled to this library.
 * Please refer to the QuickViewer source code for how to actually do it.
 *
 * This class implements the service by two instances. First create 'Reversed' instance.
 * Next you give the instance of Reversed to the constructor to create a real Translator instance.
 * Each key (eg. 'text_100003') described in the text file is temporarily set by this library,
 * and it is not related to your application.
