Applying RCS and SCCS tells you how to manage a complex software development project using RCS and SCCS. The book tells you much more than how to use each command; it's organized in terms of increasingly complex management problems, from simple source management, to managing multiple releases, to coordinating teams of developers on a project involving many files and more than one target platform.
Few developers use RCS or SCCS alone; most groups have written their own extensions for working with multiperson, multiplatform, multifile, multirelease projects. Part of this book, therefore, discusses how to design your own tools on top of RCS or SCCS, both covering issues related to "front-ending" in general, and by describing TCCS, one such set of tools (available via FTP). This book also provides an overview of CVS, SPMS, and other project management environments.
