Eclipse.py

"""
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.
