title: How to detect whether the setup runs in very silent mode?
body: <p>I know there is the <a href="http://www.jrsoftware.org/ishelp/index.php?topic=isxfunc_wizardsilent"><code>WizardSilent</code></a> function for checking whether the setup runs in silent mode, but I cannot find a function equivalent for very silent mode (when the setup is executed with <a href="http://www.jrsoftware.org/ishelp/index.php?topic=setupcmdline&amp;anchor=VERYSILENT"><code>/VERYSILENT</code></a> command line parameter).</p>
  
  <p>Is there a way to detect whether the setup runs in very silent mode?</p>
