Whats an RCS symbolic name?
RCS allows you treat a set of files as a family of files while SCCS is meant primarily for keeping the revision history of files. RCS accomplishes that with symbolic names: you can mark all the source files associated with an application version with `rcs -n’, and then easily retrieve them later as a cohesive unit. In SCCS you would have to do this by writing a script to write or read all file names and versions to or from a file.
