"""This module provides an object that creates poem-like text based on existing
poem-like text. That is, given a set of existing poems, this object creates
similar new "poems." It subclasses the generic text_generator object and serves
as an example of how to override its methods to produce new effects.

This module also provides a command-line interface to that object so that
"poems" can be generated in a terminal.
