 * List list = new List(true, 20);
 * list.add(<STRONG>new ListItem("First line")</STRONG>);

 * list.add(<STRONG>new ListItem("Third line")</STRONG>);
 * </PRE></BLOCKQUOTE>
 *
 * The result of this code looks like this:

 *			The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?

 * <B>Example 2:</B>
 * <BLOCKQUOTE><PRE>
 * List overview = new List(false, 10);
 * overview.add(<STRONG>new ListItem("This is an item")</STRONG>);
 * overview.add("This is another item");
 * </PRE></BLOCKQUOTE>
 *
 * The result of this code looks like this:
