+# dengine
+
+A Clojure library designed to implement the D-Tree engine for Arboretum.
+
+If I don't know how to write a D-engine, no one does. The engine is not (or should not be) what's complex about getting Arboretum working again; it's the user interface that's surprisingly tricky. If I can get the engine working once (without a user interface), it will make working on the user interface prototypes easier.
+
+After all, the original Acornsoft Lisp prototype didn't have a user interface.
