+
+This is a DOM-based game of Snake that I wrote in JavaScript a few years back.
+
+Other than the full screen mode demonstrated in the code, it can also be 
+initialized in div tags within a page. Example:
+
+var mySnakeBoard = new SNAKE.Board( {
+                                        boardContainer: "game-area",
+                                        fullScreen: false,
+                                        width: 580,
+                                        height:400
+                                    });
+                                    
+The comments are formatted a little strange because at the time I was playing
+around with YUI Doc.
