+You have a grid of squares, some of which contain trees. Your aim is
+to place tents in some of the remaining squares, in such a way that
+the following conditions are met:
+
+\b There are exactly as many tents as trees.
+
+\b The tents and trees can be matched up in such a way that each
+tent is directly adjacent (horizontally or vertically, but not
+diagonally) to its own tree. However, a tent may be adjacent to
+other trees as well as its own.
+
+\b No two tents are adjacent horizontally, vertically \e{or
+diagonally}.
+
+\b The number of tents in each row, and in each column, matches the
+numbers given round the sides of the grid.
+
+This puzzle can be found in several places on the Internet, and was
+brought to my attention by e-mail. I don't know who I should credit
+for inventing it.

+\IM{Tents controls} controls, for Tents
+
+Left-clicking in a blank square will place a tent in it.
+Right-clicking in a blank square will colour it green, indicating
+that you are sure it \e{isn't} a tent. Clicking either button in an
+occupied square will clear it.
+
+If you \e{drag} with the right button along a row or column, every
+blank square in the region you cover will be turned green, and no
+other squares will be affected. (This is useful for clearing the
+remainder of a row once you have placed all its tents.)
