      <documentation>
         &lt;p&gt;The Eclipse UI provides an AboutDialog that can be branded and reused by client product plugins.  This dialog typically shows the product splash image and other descriptive information about the product. The about dialog includes a button that allows the user to launch a secondary dialog, the &lt;b&gt;Installation Details&lt;/b&gt; dialog.&lt;/p&gt;
&lt;p&gt;The purpose of this extension point is to allow plug-ins to add
pages to the installation details dialog.  When the installation details dialog is opened, the pages contributed in this way will be added to the dialog box.  These pages are used to supply additional detail about the product configuration.&lt;/p&gt;

&lt;p&gt;This is an experimental extension point for an extensible about dialog.  It is not ready for production and is included at this time only for evaluation by downstream clients.  Use at your own risk.&lt;/p&gt;

This dialog typically shows the product splash image and other descriptive information about the product.
