AUTHORS
The SCCS suite was origininally written by Marc J. Rochkind at Bell Labs in 1972. Release 4.0 of SCCS, introducing new versions of the programs admin(1), get(1), prt(1), and delta(1) was published on February 18, 1977; it introduced the new text based SCCS v4 history file format (previous SCCS releases used a binary history file format). The SCCS suite was later maintained by various people at AT&T and Sun Microsystems. Since 2006, the SCCS suite is maintained by Joerg Schilling.
