           """
        def __init__(self): #inherits Cmd and  any method starting with do_ becomes a command
                Cmd.__init__(self)

                print "Hi, %s" %(getpass.getuser())

        def do_stock(self,line):  #stock command will print the latest NASDAQ value when given in a valid value
                url = requests.get('http://download.finance.yahoo.com/d/quotes.csv?s='+line+'&f=l1')
