title: IPython: Adding Javascript scripts to IPython notebook
body: <p>As a part of a project, I need to embedd some javascripts inside an IPython module.
  This is what I want to do:</p>
  
  <pre><code>from IPython.display import display,Javascript
  Javascript('echo("sdfds");',lib='/home/student/Gl.js')
  </code></pre>
  
  <p>My Gl.js looks like this</p>
  
  <pre><code>function echo(a){
  alert(a);
  }
  </code></pre>
  
  <p>Is there some way so that I can embed "Gl.js" and other such external scripts inside the notebook, such that I dont have to include them as 'lib' argument everytime I try to execute some Javascript code which requires to that library.</p>
