title: Running boomerang
body: <p>I am on Ubuntu 8.04 and I have just downloaded <a href="http://boomerang.sourceforge.net/download.php" rel="nofollow">Boomerang</a> and unzip the files into a folder on my desktop. </p>
  
  <p>I <code>cd</code> into that folder where the exe boomerang file resides, and typed <code>./boomerang</code> and <code>boomerang</code>. </p>
  
  <p>However I got the error message:</p>
  
  <blockquote>
    <p>unable to execute ./boomerang: No such file or directory.</p>
  </blockquote>
  
  <p>Why does this happen?</p>
