        For example, you can say ``term.bold`` to get the string that turns on
        bold formatting and ``term.normal`` to get the string that turns it off
        again. Or you can take a shortcut: ``term.bold('hi')`` bolds its
        argument and sets everything to normal afterward. You can even combine
        things: ``term.bold_underline_red_on_bright_green('yowzers!')``.

        For a parametrized capability like ``cup``, pass the parameters too:
        ``some_term.cup(line, column)``.

        ``man terminfo`` for a complete list of capabilities.

        Return values are always Unicode.
