DJ Programmer's Guide by Theo Skotiniotis.
In Fall 2004 there are several activities on the DJ tool:
Pengcheng Wu maintains the software and he will add Nathan Faber's extension for .jar files to DJ.
Pengcheng Wu developed a Functional Visitor implementation for DJ.
Jeff Palm ported DJ to C#. Jeff Palm will add around methods to DJ based on Functional Visitors.
Fabio Rojas extended DJ with an Argument Visitor and a generalization of traversals through edges with arguments.
We develop DJ using a Bazaar approach. Please send us your bug fixes and improvements to email@example.com and we will integrate them.
