+%description
+The Revision Control System (RCS) is a system for managing multiple
+versions of files.  RCS automates the storage, retrieval, logging,
+identification and merging of file revisions.  RCS is useful for text
+files that are revised frequently (for example, programs,
+documentation, graphics, papers and form letters).
+
+The rcs package should be installed if you need a system for managing
+different versions of files.
