#
# This library provides a framework for writing simple games in Python.
# See the examples directory for several games that illustrate simple
# use of the framework.
#
# The library provides a variety of modules including graphics, sound,
# and input handling.
#
# The graphics module provides a simple interface for creating shapes,
# images, and text on a window. The sound module supports loading and
# playing WAV files. The input module provides a way to detect and
# respond to input events including keyboard and mouse actions.
