User's Guide to the Directed Acyclic Graph Editor

This class provides a graphical editor specialized for editing a directed acyclic graph (DAG). It is automatically invoked whenever you open any file with a ".dag" extension. A DAG is a Graph that does not have cycles. Support for DAGs is built into the kernel in the DirectedAcyclicGraph class. EditDAG class is derived from the Graphics class, and therefore inherits all of its features.

Nodes in the canvas widget can be mouse sensitive. For an example of DAG, see $TYCHO/doc/tychoClasses.dag
