AppInfo is a small library that provides an easy way to show always valid, automatically updated information about a version of running software in your Web or desktop Java application. It is especially useful with automatic builds from CI server deployed on QA. It currently supports displaying the name, version, build number, and build date of running software. This information is available as text from end application and can be customized to fit your needs. Source information can be passed via environment variables and works out-of-box with Hudson CI server.
