+>> Enter a fileName: Localizable.strings
+>> Supports languages:
+['auto', 'zh', 'en', 'yue', 'wyw', 'jp', 'kor', 'fra', 'spa', 'th', 'ara', 'ru', 'pt', 'de', 'it', 'el', 'nl', 'pl', 'bul', 'est', 'dan', 'fin', 'cs', 'rom', 'slo', 'swe', 'hu', 'cht', 'vie']
+>> Enter from language: zh
+>> Enter to language list, split by space: cht en jp kor
+>> Start
+Translating cht to fileName: Localizable_cht.strings
+Finished translating to cht
+Translating en to fileName: Localizable_en.strings
+Finished translating to en
+Translating jp to fileName: Localizable_jp.strings
