title: What is this Chrome debugger VM script?
body: <p>You can find this file by calling <code>dir(obj)</code> in the Chrome dev tools console and clicking the link display on the right pointing to where <code>dir</code> is defined in this file.</p>
  
  <p>What are the details behind this file?</p>
  
  <p>Is this the script that is part of Chrome's debugger or is it some interface with V8?</p>
  
  <p>Why is there a 2007 Apple copyright at the top?</p>
  
  <p>When I open this file the numeric identifier after VM is always different. Where does the VMXXXX identifier come from?</p>
  
  <p>Are there anymore of these files publicly visible like this and, if so, how do you access them?</p>
  
  <p>Thanks!</p>
