boot loader translations
------------------------

o How do I add a new text?

  - Use the gfxboot/po/bin/add_text script; example:

      add_text help 'Help'

    This will define txt_help; the 'txt_' prefix is optional.

o How do I remove a text that's no longer needed?

  - Use the gfxboot/po/bin/rm_text script; example:

      rm_text help

    This will remove txt_help; the removed lines are stored in the 'old'
    directory.

o How do I add a new language?

  - Copy bootloader.pot to <lang>.po. Remember to get <lang>.po translated.
