RAT helps with release auditing for open source projects.
Auditing a release is a slow and tedious business. RAT aims to automate and speed this process.
This is based on an Apache Incubator itch: lots of projects new to Apache which want to create releases compliant with Apache policy. Auditing these to check that all appropriate source files have license headers, that required documents are in the right places and that there are no incompatible licenses is tedious and time consuming.
RAT is coded in Java to easily allow a cross-platform UI to be added but its auditing is not restricted to a particular language.
