title: Detect versionNumber from MyProject-App.xml? Adobe AIR
body: <p>The desktop application I'm working on is being developed in Adobe AIR + Flex + As3. Now I want to detect the versionNumber parameter on the accompanying XML description file for the AIR app.</p>
  
  <pre><code>&lt;!-- A string value of the format &lt;0-999&gt;.&lt;0-999&gt;.&lt;0-999&gt; that represents application version which can be used to check for application upgrade. 
  Values can also be 1-part or 2-part. It is not necessary to have a 3-part value.
  An updated version of application must have a versionNumber value higher than the previous version. Required for namespace &gt;= 2.5 . --&gt;
  &lt;versionNumber&gt;1.0.0&lt;/versionNumber&gt;
  </code></pre>
  
  <p>Is there a variable or property that I can use to access this? For example in the About box of the app, instead of manually editing the version displayed, I want it to rely on this one.</p>
