Usage

Usage:  gtrans [flags] [input text]
        gtrans translates input text specified by argument or STDIN using Google Translate.
        Source language will be automatically detected.

        export GOOGLE_TRANSLATE_API_KEY=<Your Google Translate API Key>

        [optional]
        export GOOGLE_TRANSLATE_LANG=<default target language (e.g. en, ja, ...)>
        export GOOGLE_TRANSLATE_SECOND_LANG=<second language (e.g. en, ja, ...)>

        If you set both GOOGLE_TRANSLATE_LANG and GOOGLE_TRANSLATE_SECOND_LANG,
        gtrans automatically switches target langage.

        Example:
                $ gtrans "Golang is awesome"
                Golangは素晴らしいです
                $ gtrans "Golangは素晴らしいです"
                Golang is great
                $ gtrans "Golangは素晴らしいです" | gtrans | gtrans | gtrans ...
