         Extension point for registering global install handlers. Global
install handlers can be referenced by features 
(using the &lt;code&gt;&amp;lt;feature&amp;gt; &amp;lt;install-handler&amp;gt;&lt;/code&gt;
tags) without having to include a copy of the handler code as
part of the downloadable feature.

         The following is an example of new global install handler registration:
&lt;p&gt;
&lt;pre&gt;
   &lt;extension
        id=&quot;custom&quot;
        point=&quot;org.eclipse.update.core.installHandlers&quot;
        name=&quot;Custom install handler&quot;&gt;
     &lt;install-handler
        class=&quot;com.xyz.update.CustomInstallHandler&quot;&gt;
     &lt;/install-handler&gt;

         Registered install handler classes must implement 
&lt;code&gt;org.eclipse.update.core.IInstallHandler&lt;/code&gt; interface.
Implementers should extend base class &lt;code&gt;org.eclipse.update.core.BaseInstallHandler&lt;/code&gt;.

         The platform supplies a simple install handler that is registered as &lt;code&gt;org.eclipse.update.core.DefaultInstallHandler&lt;/code&gt;. If used, it will copy any non-plug-in data entries provided with the feature into the feature installation directory.
