What’s the best way to define new page types in an extension?

I created some classes that extend StandardPage, but they aren’t loaded.  
(Don’t appear in the page type drop-down)

I reference my page extensions during the load of the extension:

[http://soxbox.no-ip.org/radiant/svn/extensions/x\_groggy/x\_groggy\_extensi](http://soxbox.no-ip.org/radiant/svn/extensions/x_groggy/x_groggy_extensi)

If you extend Page, make sure to mention the class name on its own  
line in the activate method of your extension. This will force Rails  
to load the class. In certain Rails modes (i.e. development,  
production, etc), the class will not be found otherwise.
