title: How to get source package with aptitude on linux?
body: <p>I can get source packages using apt-get source , but there a way to do this using aptitude ?
  Also I downloaded the .deb package for python2.6 using aptitude and then unzipped it using ar.</p>
  
  <pre><code>aptitude download python2.6
  ar xv python2.6_2.6.5-1ubuntu6_i386.deb
  </code></pre>
  
  <p>I also downloaded the python source using apt-get</p>
  
  <pre><code>sudo apt-get source python2.6
  </code></pre>
  
  <p>The contents of both the downloads are different. Why ?</p>
