Changes

For commands that are more complicated than our simple "hello-world" command, you can use the helper function <code>CmdUtils.CreateCommand()</code>, which takes an options dictionary. To redo the "hello-world" command using the convenience function, we'd write: <pre>CmdUtils.CreateCommand({ name: "hello-world", execute: function() { displayMessage( "Hello, World!" ); }})</pre> This may not seem to be much of a win (and it isn't for simple commands) but as the commands become more complex, you'll see that it helps a lot. For one, you can name the command more freely with the method&mdash;unicode non-English characters are now fair game. There are a number of other useful functions in the <code>CmdUtils </code> namespace. We don't yet have full documentation for these commands, but you'll get a sense of the useful ones in this tutorial.
