This script demonstrates how to use the PyObjCTools.Conversion module to convert between a python and Objective-C representation of a data structure.

Note that most code doesn’t need to perform this conversion because the Python representation is automatically proxied to the Objective-C world with an interface that matches the Objective-C interface.
