 <h2><a name="1.3"></a>1.3. Why the name change from TIP?</h2>
 <blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>
