Rails - Jun 2006 - Getting list of loaded plugins

According to the docs I''ve read, the loaded_plugins variable is made
available in any plugin''s init.rb file.  How can I access the list of
plugins from outside of init.rb?  For example if I''m at the console
and want to see what plugins are loaded how could I do that?
Basically I''d just like to use the equivalent of loaded_plugins
outside of init.rb.
