+In \q{Unequal} mode, the clue signs are greater-than symbols indicating one
+square's value is greater than its neighbour's. In this mode not all clues
+may be visible, particularly at higher difficulty levels. 
+
+In \q{Adjacent} mode, the clue signs are bars indicating
+one square's value is numerically adjacent (i.e. one higher or one lower)
+than its neighbour. In this mode all clues are always visible: absence of
+a bar thus means that a square's value is definitely not numerically adjacent
+to that neighbour's.
