    Used to generate translations from __('string to translate', 'text-domain') functions.

    MO files: MO, or Machine Object is a binary data file that contains object data referenced by a program. It is typically used to translate program code, and may be loaded or imported into the GNU gettext program.

    PO files: PO files are the files which contain the actual translations. Each language will have its own PO file, for example, for French there would be a fr.po file, for german there would be a de.po, for American English there might be en-US.po.

    POT file: POT files are the template files for PO files. They will have all the translation strings left empty. A POT file is essentially an empty PO file without the translations, with just the original strings.

    wp i18n make-pot . languages/<file-name>.pot --domain=<domain-name>

wp i18n make-mo languages/<file-name>.po languages/

wp i18n make-php languages/

    It is possible to specify a specific Domain Path in style.css: Defaults to /languages.

    The Text Domain has to be specified in the style.css file.

    The function load_theme_textdomain( $text_domain, $path ); needs to be called with the after_setup_theme hook.
