Class Diagram Example: Multiple Views

Vadim Nasardinov noted that an advantage of UMLGraph over many GUI-oriented UML drawing tools is the ability to generate different views of a diagram from the same source description. The following two diagrams were generated from the same source; a Makefile illustrates a way to organize this process.
