PhantomJS Child Process Module
<p>I've been trying to find out how to use PhantomJS's child process module, but documentation is very scarce: <a href="http://phantomjs.org/api/child_process/" rel="nofollow">http://phantomjs.org/api/child_process/</a></p>

<p>Where can I find more documentation on how to use the child process module? The API only documents the <code>spawn</code> command. How do I use <code>execFile</code> and <code>kill</code>? Are these all the methods there are? What does <code>communicate with them via stdin / stdout / stderr</code> mean? </p>
