incorrect documentation

Following the documentation, this does not work (copied from the documentation page):

grunt.initConfig({
  express: {
    myServer: {
      server: path.resolve(__dirname, 'server.js')
    }
  }
});

This does:

grunt.initConfig({
  express: {
    myServer: {
     options: {
      server: path.resolve(__dirname, 'server.js')
     }
    }
  }
});

I.e., server must be nested in options object.
