    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.
