          in apps.properties add this to enable the app
          (it's pointing to folder ~/helloworld we create later)

helloworld
helloworld.mountpoint = /helloworld
helloworld.repository.1 = ~/helloworld/

         then create the app by creating those folders:

~/helloworld/Root/Root.actions.js:


     and in the js file:

Root.prototype.main_action = function() {
        res.writeln("hello world");
        return;
}
