SCCS 5.09 22 Feb 2019
SCCS is an implementation of the POSIX standard Source Code Control System. It is based on the original UNIX SCCS code provided by Sun as part of OpenSolaris and was made portable to other platforms. This version is a major enhancement on the original code.
major feature: Many new features. Many bug fixes. More SCCSv6 features, another important step towards supporting whole projects instead of single files. All SCCS commands now support the -N bulk option to handle multiple files as a preparation of the upcoming project mode. For more information see the very explicit AN-5.09
