Are there best-practices for creating wizards or asking various 
questions (whether yes/no or text/numeric entry) in a cmd.Cmd 
class?  Something like the imaginary confirm() and get_string() 
methods here:

   class MyCmd(cmd.Cmd):
     def do_name(self,line):
       s = get_string(prompt=line, default="Whatever")
       ...
     def do_save(self,line):
       if os.path.isfile(line):
         if not confirm("%r exists. Continue?", True): return
       self.save(line)
     def save(self, filename):
       ...

I can monkey with printing messages and using raw_input(), but 
I'd like to know if there's a better way (such as something 
interacting with readline for 
text-entry-with-history-and-completion, or raw-character input 
for Y/N answers rather than the need to hit <enter>, making it 
feel more uniform),

Thanks,
