    @class wxRichTextHeaderFooterData


    This class represents header and footer data to be passed to the
    wxRichTextPrinting and wxRichTextPrintout classes.

    Headers and footers can be specified independently for odd, even or both page
    sides. Different text can be specified for left, centre and right locations
    on the page, and the font and text colour can also be specified.

    You can specify the following keywords in header and footer text, which will
    be substituted for the actual values during printing and preview.

    - @@DATE@: the current date.
    - @@PAGESCNT@: the total number of pages.
    - @@PAGENUM@: the current page number.
    - @@TIME@: the current time.
    - @@TITLE@: the title of the document, as passed to the wxRichTextPrinting or
      wxRichTextLayout constructor.
