+JavaScript Snake<br/>
+By Patrick Gillespie<br/>

+
+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.
