title: Calling one command from another
body: <p>I want to do some kind of alias, for example, <code>hubot status</code> should call <code>hubot newrelic me</code> and <code>hubot gauges for today</code>.</p>
  
  <p>I tried to do things like `msg.send "hubot newrelic me", but seems like hubot just ignore the message.</p>
  
  <p>How can I do that?</p>
