+\cfg{winhelp-topic}{games.map}
+
+You are given a map consisting of a number of regions. Your task is
+to colour each region with one of four colours, in such a way that
+no two regions sharing a boundary have the same colour. You are
+provided with some regions already coloured, sufficient to make the
+remainder of the solution unique.
+
+Only regions which share a length of border are required to be
+different colours. Two regions which meet at only one \e{point}
+(i.e. are diagonally separated) may be the same colour.
+
+I believe this puzzle is original; I've never seen an implementation
+of it anywhere else. The concept of a four-colouring puzzle was
+suggested by Owen Dunn; credit must also go to Nikoli and to Verity
+Allan for inspiring the train of thought that led to me realising
+Owen's suggestion was a viable puzzle. Thanks also to Gareth Taylor
+for many detailed suggestions.

+To colour a region, click the left mouse button on an existing
+region of the desired colour and drag that colour into the new
+region.
+
+(The program will always ensure the starting puzzle has at least one
+region of each colour, so that this is always possible!)
+
+If you need to clear a region, you can drag from an empty region, or
+from the puzzle boundary if there are no empty regions left.
+
+Dragging a colour using the \e{right} mouse button will stipple the
+region in that colour, which you can use as a note to yourself that
+you think the region \e{might} be that colour. A region can contain
+stipples in multiple colours at once. (This is often useful at the
+harder difficulty levels.)
+
+If you press L during play, the game will toggle display of a number
+in each region of the map. This is useful if you want to discuss a
+particular puzzle instance with a friend \dash having an unambiguous
+name for each region is much easier than trying to refer to them all
+by names such as \q{the one down and right of the brown one on the
+top border}.

+You are a small green ball sitting in a grid full of obstacles. Your
+aim is to collect all the gems without running into any mines.
+
+You can move the ball in any orthogonal \e{or diagonal} direction.
+Once the ball starts moving, it will continue until something stops
+it. A wall directly in its path will stop it (but if it is moving
+diagonally, it will move through a diagonal gap between two other
+walls without stopping). Also, some of the squares are \q{stops};
+when the ball moves on to a stop, it will stop moving no matter what
+direction it was going in. Gems do \e{not} stop the ball; it picks
+them up and keeps on going.
+
+Running into a mine is fatal. Even if you picked up the last gem in
+the same move which then hit a mine, the game will count you as dead
+rather than victorious.
+
+This game was originally implemented for Windows by Ben Olmstead
