sccs utility is available with
CSSC. The code has
been adapted to support GNU Autoconf, but it should function in the same
way. The only difference between the operation of the original BSD
sccs program and that of the one provided by
CSSC is that
way that the called programs are searched for. While the original
program has the paths hard-coded in as /usr/sccs/*, the version
CSSC first searches for them on the PATH, and then
falls back on /usr/sccs/*. If the executable is running
PATH environment variable is ignored. The
sccs program itself should be fairly secure, but the other
programs in the suite are not. See Known Problems, for more
sccs program is documented in its online manual page, and
also in An Introduction to the Source Code Control System by Eric
Allman, a copy of which is included with this suite.
Unlike all the other parts of the suite, the
sccs program and its
accompanying documentation are covered by the BSD copyright license; see
BSD Code, and the file COPYING.bsd, for more information.
The original BSD version of the
sccs program can easily be found
on BSD mirrors, for example ftp://ftp.freebsd.org/.
