+a single nim stick and @code{\\nimgame} which represents games of multi-pile
+Nim.  Nim sticks are drawn with a little random wobble so they look thrown
+together and not too regular.  The package also provides options to customise
+the size and colour of the sticks, and flexibility to draw heaps of different
+objects.")
