/**
* (<b>Entry point</b>) Demonstrates how to write a very simple tunneling proxy
* using MINA. The proxy only logs all data passing through it. This is only
* suitable for text based protocols since received data will be converted into
* strings before being logged.
* <p>
* Start a proxy like this:<br/>
* <code>org.apache.mina.example.proxy.Main 12345 www.google.com 80</code><br/>
* and open <a href="http://localhost:12345">http://localhost:12345</a> in a
* browser window.
