This folder contains UML diagrams for certain implementations within this project. To view/edit them, you need "Poseidon for UML". The free community edition (which is completely sufficient for all documents herein) is available from http://www.gentleware.com/. It is probably also possible to open the documents with ArgoUML, the free open source UML tool which Poseidon for UML is based on. Visit http://argouml.tigris.org/ to obtain ArgoUML.
