    Place the URL of an RSS feed in the $file variable.
      
       The $rss_channel array will be filled with data from the feed,
       every RSS feed is different by by and large it should contain:
      
       Array {
           [TITLE] = feed title
           [DESCRIPTION] = feed description
           [LINK] = link to their website
          
           [IMAGE] = Array {
                       [URL] = url of image
                       [DESCRIPTION] = alt text of image
                   }
          
           [ITEMS] = Array {
                       [0] = Array {
                               [TITLE] = item title
                               [DESCRIPTION] = item description
                               [LINK = a link to the story
                           }
                       .
                       .
                       .
                   }
       }
      
       By default it retrives the Reuters Oddly Enough RSS feed. The data is put into the array
       structure so you can format the information as you see fit.
