- * Message translations.
- *
- * This file is automatically generated by 'yii message' command.
- * It contains the localizable messages extracted from source code.
- * You may modify this file by translating the extracted messages.
- *
- * Each array element represents the translation (value) of a message (key).
- * If the value is empty, the message is considered as not translated.
- * Messages that no longer need translation will have their translations
- * enclosed between a pair of '@@' marks.
- *
- * Message string can be used with plural forms format. Check i18n section
- * of the guide for details.
- *
- * NOTE: this file must be saved in UTF-8 encoding.
