Level 3 hints for clp
---------------------

Here's I chose to structure my solution, including a complete main.	
	
	public class clp {
		public static void main(String args[]) throws IOException {
			BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
	
			String line;
			while ((line = in.readLine()) != null) {
				System.out.println("----------------------------------------");
				System.out.println("Command line: " + line);
				processLine(line);
			}
		}
	
		private static void processLine(String line) {
			...
		}
	
		private static void processCommand(ArrayList<String> words, boolean first, boolean last) {
			...
		}
	}
