    General purpose message dialog. @c style may be a bit list of the
    following identifiers:

    @beginStyleTable
    @style{wxYES_NO}:
        Puts Yes and No buttons on the message box. May be combined with
        wxCANCEL.
    @style{wxCANCEL}:
        Puts a Cancel button on the message box. May only be combined with
        wxYES_NO or wxOK.
    @style{wxOK}:
        Puts an Ok button on the message box. May be combined with wxCANCEL.
    @style{wxICON_EXCLAMATION}:
        Displays an exclamation mark symbol.
    @style{wxICON_HAND}:
        Displays an error symbol.
    @style{wxICON_ERROR}:
        Displays an error symbol - the same as wxICON_HAND.
    @style{wxICON_QUESTION}:
        Displays a question mark symbol.
    @style{wxICON_INFORMATION}:
        Displays an information symbol.

    The return value is one of: wxYES, wxNO, wxCANCEL, wxOK. For example:

    be split into separate lines, to cater for large messages.
