<p>I love <strong>Python</strong> ... I couldn't resist writing you some code. It would be easy to generalize it to check all the files in a directory ... but I'm trying to hook you!</p>
<p>I am sure it could be done in a more Pythonic way, but python is great for string stuff -- way more readable than <strong>Perl</strong>. (<em>Flame war alert!</em>)</p>
