------------------------------------------------------------------------------
  == The Example ==
  
  Consider this as a plugin example: You want to be able to recommend specific 
web pages for given searches.  For example, the site you're indexing has a 
section on writing plugins for nutch.  If someone searches for the term 
"plugin" you want to be able to recommend that they start at the homepage for 
the plugins section.
+ 
+ You go through your site and add meta-tags to pages that list what terms they 
should be recommended for.
+ 
+ In order to do this we'll need to write a plugin that extends 3 different 
extension points.  We need to extend the HTMLParser in order to get the 
recommended terms out of the meta tags.  The IndexingFilter will need to be 
extended to add a recommended field to the index. 
  
  == Setup ==
