          AutoDia is a modular application that parses source code, XML or data
          and produces an XML document in Dia format (or images via graphviz
          and vcg).  Its goal is to be a UML / DB Schema diagram autocreation
          package.  The diagrams its creates are standard UML diagrams showing
          dependencies, superclasses, packages, classes and inheritances, as
          well as the methods, etc of each class.
  
          AutoDia supports any language that a Handler has been written for,
          which includes C, C++, Java, Perl, Python, and more.
