Apache Whisker

Apache Whisker is a tool developed by the Apache Creadur project to assist in maintaining correct legal documentation for assembled software applications. It is language- and build-agnostic, meaning it can be used across various programming environments and build systems. Whisker helps developers and organizations manage licensing metadata, generate legal documents like LICENSE and NOTICE files, and audit software distributions for compliance. It is particularly useful for complex applications composed of multiple third-party libraries and frameworks, where tracking and maintaining accurate legal documentation can be challenging. Whisker is not a substitute for legal advice but serves as a practical aid in organizing and verifying licensing information.
