its just a simple rss reader. i'm writing it almost purely just to
get me using language (i'm learning python) it lets you save rss
feeds, and to do this one would specify a name and url (ie you have to
specify both), but there are other things it can do (remove a rss
feed, view a feed) hence i thought it was best to using command line
