title: How to supply options to the python interpreter when using iPython
body: <p>For example, if I wanted to avoid generation of <code>.pyc</code> files when using the usual <code>python</code> command I would write:</p>
  
  <pre><code>python -B script.py
  </code></pre>
  
  <p>But what if I want to use <code>ipython</code> instead? All I know is that </p>
  
  <pre><code>ipython -B script.py
  </code></pre>
  
  <p>doesn't work</p>
