Introduction to CSSC
CSSC is the GNU Project's
replacement for SCCS.
SCCS is a proprietary suite of tools which is provided with most
commercial versions of Unix. The purpose behind CSSC is to provide a
work-alike for SCCS which can be used on the various
Free versions of
What is SCCS?
SCCS was the only major form of source code control on Unix
platforms for many years, until RCS came
along. SCCS was an effective method for small projects, but these days
is less popular, particularly for projects involving large numbers of
files. A fair amount of old software is still in SCCS form, and CSSC
is designed to retrieve that software. Once retrieved, it is highly
recommended to bring the source under the control of more modern
source code control systems, such as
The history of CSSC is documented in a
CSSC can be found on
[via http] and
It can also be found on one of our FTP mirrors.
The latest bleeding-edge version of the source code, along with a
revision history, can be found in the CSSC Savannah
repository. Assuming you have git installed, you can retrieve the
bleeding-edge version with the following command:
git clone git://git.savannah.gnu.org/cssc.git
The bleeding-edge version contains a file README-hacking
that contains instructions for building from bleeding-edge sources.
Please note that we do not suggest using test versions of CSSC
for production use.
A manual is available online.
You may also find more information about CSSC by looking at
your local documentation. For example, you might try info
cssc at the shell prompt.
You can subscribe to any GNU mailing list via the web. See for
example the web page for the
firstname.lastname@example.org mailing list.
If you don't have convenient web access, you can send an empty mail
with a Subject: header line of just "subscribe" to the relevant
-request list. For example, to subscribe yourself to the cssc-users
list, you would send mail to email@example.com
with no body and a Subject: header line of just "subscribe".
It has been necessary to moderate the CSSC mailing list to prevent the
flood of spam. Postings to the lists are held for release by
the list moderator. Sometimes the moderators are unavailable for
brief periods of time. Please be patient when posting. If you
don't see the message in the list archive then it did not get posted.
Important announcements about CSSC and most other GNU Software are
also made on
Test releases of CSSC are announced on the
Enhancement Requests and Bug Reports
CSSC's goal is compatibility with SCCS. Incompatibilities between the
two (except for the removal of arbitrary limits) are bugs in CSSC.
Please report bugs in CSSC via the
CSSC bug reporting
page. First though, please check that the bug hasn't already
been fixed in a later release of CSSC.
If you would like any new feature to be included in future versions of
CSSC, please make your suggestion on the <firstname.lastname@example.org>
Please remember that development of CSSC is a volunteer effort, and you
can also contribute to its development. For information about contributing
