// This example shows simple usage of the wrapped Shape classes.
// The main purpose of this example is to show the doxygen comments translation to JavaDoc comments.
// Users should look at the generated .java files and if javadoc is installed and working on your system,
// the generated Java docs can be viewed in a browser by opening the javadocs/index.html file.
