This book tells the reader how to manage a complex software development project using RCS and SCCS. The book is organized in terms of increasingly complex management problems, from simple source management, to managing multiple releases, to co-ordinating teams of developers on a project involving many files and many target platforms. Few developers use RCS or SCCS alone; most groups have written their own extensions for working with multi-person, multi-platform, multi-file, multi-release projects. Part of this book, therefore, discusses how to design and build your own tools on top of RCS or SCCS. The authors present their design for TCCS, one such set of tools (available via FTP). This book also provides an overview of CVS, SPMS, and other project management environments.
