title: Compare versions without using version CPAN module
body: <p>Assume I have 2 version variables:</p>
  
  <pre><code>$one = "1.2.3"
  $two = "1.2.4"
  </code></pre>
  
  <p>How do I compare these two version variables on whether the versions match OR one > two OR one &lt; two?</p>
  
  <p>Please note that I have a read-only system where I cannot add any Perl modules. Hence I cannot add <code>version</code> Perl module.</p>
