title: How can I enable or disable the eclipse new wizard?
body: <p>My RCP application (based on the Eclipse infrastructure) has several modules. These modules can be enabled or disabled depending on the status of the application, and this information is available via <a href="http://wiki.eclipse.org/Command_Core_Expressions" rel="nofollow" title="variables">variables</a> (you can think about the active perspective).</p>
  
  <p>Additionally, each module contribute to the new wizards (extension point "org.eclipse.ui.newWizards") to provide the user with the ability to create certain elements. But this is allowed only if the module is enabled...</p>
  
  <p>Is there a way to enable or disable "new wizard"s depending on the status of the RCP application?</p>
