Apache Rat is a release audit tool. It improves accuracy and efficiency when checking releases. It is heuristic in nature: making guesses about possible problems. It will produce false positives and cannot find every possible issue with a release. Its reports require interpretation. In response to demands from project quality tool developers, Rat is available as a library suitable for inclusion in tools. This POM describes that library. Note that binary compatibility is not guaranteed between 0.x releases. Apache Rat is developed by the Apache Creadur project, a language and build agnostic home for software distribution comprehension and audit tools.
