+Eclipse.py by Bruce Eckel, for Thinking in Java 4e
+Modify or insert package statments so that Eclipse is happy with the code tree.
+Run this with no arguments from the root of the code tree.
+
+The Ant build will not work once you run this program!
+
+You may also want to modify the dotproject and dotclasspath text below.
+
+You must have Python 2.3 installed to run this program. See www.python.org.
