title: pyserial: No module named tools
body: <p>I have installed the latest pySerial on my Ubuntu box with python 2.7.2, and it works fine for most things, but whenever I try to import the 'tools' package, it says that it can't find 'tools'. The <a href="http://pyserial.sourceforge.net/shortintro.html?highlight=list#listing-ports" rel="noreferrer">documentation for pySerial</a> explicitly references this 'tools' package.</p>
  
  <pre><code>&gt;&gt;&gt; from serial import tools
  Traceback (most recent call last):
    File "&lt;pyshell#30&gt;", line 1, in &lt;module&gt;
      import serial.tools
  ImportError: No module named tools
  </code></pre>
  
  <p>and when I:</p>
  
  <pre><code>&gt;&gt;&gt; serial.VERSION
  '2.5'
  </code></pre>
  
  <p>which is the latest version according to <a href="http://sourceforge.net/projects/pyserial/" rel="noreferrer">Source Forge</a></p>
  
  <p>So why can't I get to the 'tools' package of pySerial?</p>
