title: Step by step instructions on building Sphinx 4
body: <p>I want to run a demo for Sphinx 4 using the steps given here: <a href="http://cmusphinx.sourceforge.net/sphinx4/" rel="nofollow">http://cmusphinx.sourceforge.net/sphinx4/</a><br>
  However, I don't understand what it's trying to tell me<br>
  I have java, jre, eclipse-juno and everything needed to compile java as well as android programs
  But the tutorial I linked says I should run ant<br>
  What is ant and how do I run it?<br>
  In one of the steps it tells to set environment variables related to java and ant, and it says to do so using  </p>
  
  <pre><code>export JAVA_HOME=/usr/local/jdk1.6.0_14
  export ANT_HOME=/usr/local/apache-ant-1.8.0
  export PATH=/usr/local/jdk1.6.0_10/bin:/usr/local/apache-ant-1.8.0/bin:$PATH  
  </code></pre>
  
  <p>I thought it was supposed to be done in the <code>Environment Variables</code> in My Computer properties. What is this export command?  </p>
  
  <p>Is there an easy to understand step by step guide that shows how to run a demo program for Sphinx 4?</p>
