 //   partition_cut_mask(l, w, h, [cutsize], [cutpath], [gap], [inverse], [spin], [orient]);
 // Description:
 //   Creates a mask that you can use to difference with an object to cut it into two sub-parts that can be assembled.
+//   The `$slop` value is important to get the proper fit and should probably be smaller than 0.2.  The examples below
+//   use larger values to make the mask easier to see.  
 // Arguments:
 //   l = The length of the cut axis.
 //   w = The width of the part to be masked, back from the cut plane.
