+\section DependenciesIntro Introduction
+
+A script that runs nightly maps out he dependencies between source
+files in the Audacity code base.  We aim for this graph to be 
+relatively untangled, spearation of concerns, so that classes can 
+be understood better on their own, without having to read many other
+source files.
+
+This presentation of the dependencies, and indeed the actual network
+of the dependencies are works in progress.  We aim to improve both.
