title: execute npm script from another package
body: <p>Suppose I have 2 node packages, one called <code>parent</code> and one called <code>child</code>. child has a <code>package.json</code> with some scripts.  Is it possible to <em>include</em> the scripts from <code>child</code> in the context of <code>parent</code>?</p>
  
  <p>For example:</p>
  
  <p>child/package.json:</p>
  
  <pre><code>"scripts":{
     "hello":"echo hello"
  }
  </code></pre>
  
  <p>parent/package.json:</p>
  
  <pre><code>"dependencies":{"child":"1.0.0"}
  </code></pre>
  
  <p>Then from the command line in the <code>parent</code> directory:</p>
  
  <p><code>parent&gt; npm run hello</code> //outputs hello</p>
