+To impose with rotated pages, for example to put two A4 portrait pages two-up on an A3 landscape page, rotate them prior to imposition.
 
 Two other ways of putting multiple pages on a single page remain from earlier versions of \texttt{cpdf} which lacked a general imposition operation.  The \texttt{-twoup-stack} operation puts two logical pages on each physical
 page, rotating them 90 degrees to do so. The new mediabox is thus larger. The \texttt{-twoup} operation does the same, but scales the new sides down so
