rotpages – Typeset sets of pages upside-down and backwards

The rot­pages pack­age al­lows you to for­mat doc­u­ments where small sets of pages are ro­tated by 180 de­grees and re­ar­ranged, so that they can be read by turn­ing the printed copy up­side-down. It was de­vel­oped for col­lect­ing ex­er­cises and so­lu­tions: us­ing the pack­age, you can print the ex­er­cise text nor­mally and the so­lu­tions ro­tated.
