Another tool from the great Thoughtworks people. It "provides a set of Ant build files to simplify configuring many of the most popular tools. Setting up a project can be as simple as:
Download and extract Panopticode in your project's home directory
Copy the PROJECT_HOME/panopticode/build-example.xml file to PROJECT_HOME/build.xml
edit the PROJECT_HOME/build.xml to specify your classpath and source code directory.
(optional) Select your source code management tool in the PROJECT_HOME/panopticode/panopticode-imports.xml
The whole thing can be easily done in 5 minutes. If you have a fast internet connection you could probably pull it off in 2 minutes :)"
