hello world

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;
  }
