1. Configuration and Release management using AtFS. ShapeTools is a collection of programs to support software configuration management in an UNIX environment. It consists of a set of version and attribute control commands, and a configuration interpreter and build tool ("shape"). The toolkit is integrated on top of the Attributed File System (AtFS). ShapeTools is designed to live meaningfully together with any other UNIX tool operating on regular files. This distribution also contains a prototype for a comprehensive change control and release management system designed to manage the evolution of system releases in multi programmer software development efforts.
