# It's missing comments
# It doesn't tell the user what it is
# It doesn't validate the inputs
# BUT ... this is clever - a documentation string ...

Whose nose was exceedingly bent
\tHe followed in one day
\tor thats what they say
and no-one knows where he went"""
# ... which is printed out when the program runs!
