Generates a text, XML, or HTML report of the API differences between two versions of an Objective-C library. It assists library authors with creating a diff report for their users and verifying that no unexpected API changes have been made.
Beta. The tool has been tested against the system frameworks and a number of third-party libraries, but I'd like to open it to feedback and additional testing before considering the command line interface and XML format stable.
