   Loading varioref enables you to refer to sub-exercises, like 
   this: Did you do \ref{subex:man2}?

+    \begin{solution}[defersolutiontitle]
+      \begin{frame}
+        This is a dual-use solution with explicit
+        beamer frames (and no framed).
+        \solutiontitle
+        Note, that we can freely place the title, because of

+    \begin{solution}
+      This solution is only shown if using the non-beamer version, because the option beamersolution was used. Otherwise both
+      solutions would be shown. You can set
+      the option beamersolution for individual (normal) solutions
