+     <p>
+       The <var>roadLength</var> game input variable used to be the
+       cardinal number of positions the troll could be in.  That's the
+       way it was presented in the original game, but I leaned more
+       towards distances to make the I/O protocol easier on beginners.
+       So it's currently inconsistent.
+     </p>
+     <p>
+       This is going to change in the following days to be a distance
+       everywhere, more in line with the protocol's other measures.
+       Not to mention being somewhat more consistent with the variable
+       name.  Thanks

+       If you used this variable, I suggest you temporarily used one
+       of these workarounds so you don't get bit by the upcoming
