Rails - Feb 2005 - View helper usage in a non rails class

I am working on a rails portal application as a pet project, and I am stumped 
on gaining access to the view helper methods from a non-rails descended 
class.  Basically I am trying to allow a portlet to create its content with 
the same ease that the normal rails templates allow.  How do I go about 
adding in the view helpers?

Thanks,
Phil
