Rat audits software distributions, with a special interest in headers. If this isn't quite what you're looking for then take a look at the other products developed by Apache Creadur™, including Apache Whisker™ which audits and generates legal (for example LICENSE) documents for complex software distributions.
Run from the command line with:
java -jar apache-rat/target/apache-rat-0.17-SNAPSHOT.jar --help
This will output a help message detailing the command line options available to you.
Rat can be used to automatically add license headers to files that do not currently have them. Only files that are not excluded by the Rat configurations will be affected.
To add license headers use a command such as:
java -jar apache-rat/target/apache-rat-0.17-SNAPSHOT.jar --addlicense --copyright "Copyright 2008 Foo" --force /path/to/project
This command will add the license header directly to the source files. If you prefer to see which files will be changed and how then remove the "--force" option.
It is common to use the Rat with the Maven or Ant plugins and specify a series of files to exclude (such as a README or version control files). If you are using the Rat application instead of a plugin you can specify a series of regex excludes in a file and specify that with the --exclude-file option.
java -jar apache-rat/target/apache-rat-0.17-SNAPSHOT.jar --exclude-file /path/to/project/.rat-excludes /path/to/project

====== Notes ======
1. Rat highlights possible issues.
2. Rat reports require interpretation.
3. Rat often requires some tuning before it runs well against a project.
4. Rat relies on heuristics: it may miss issuesRAT allows you to style the output as you see fit. Three stylesheets are included in the "rat" package.
These stylesheets can be specified using options in the command line, Maven or Ant clients.
