    Use the tasks below to export strings that are marked for translation from the app, and import translated strings back into the app.
    The app uses angular-gettext to provide the export, import and on-the-fly translation functions. https://angular-gettext.rocketeer.be/
    Follow the guide on the angular-gettext website to learn how to mark a string for translation.

    To use the tool
    - Install grunt and angular-gettext, as per package.json

    To export strings for translation:
    - From the root of the app, run grunt nggettext_extract
    - This will create a file located in languages/temple/template.po that indicates all of the strings that need to be translated. Have this file translated for each language.

    To import strings that have been translated
    - Copy the .po file for each language into the respectve folder in languages/language-code/language-code.po
      - For example, the Russian translation should be located in languaged/ru/ru.po
    - After all .po files have been copied into each language folder, from the root of the app, run grunt nggettext_compile.
      - This takes all of the translated strings and copies them into .json files that are used by the app to provide translations.

    To add support for a new language
    - Create a new folder for the language under languages/language-code, for example, languages/ru for Russian.
    - Have the template.po file translated into that language.
    - Import the translated strings, as per the above section.
    - Update $rootScope.languages in app/app.js with the language name and code
