Editing Source Code Control System (section)

=== Other version control systems ===
Since the 1990s, [[List of version control software|many new version control systems]] have been developed and become popular that are designed for managing projects with a large number of files and that offer advanced functionality such as multi-user operation, access control, automatic building, network support, release management and [[distributed version control]]. [[Bitkeeper]] and [[TeamWare]] use the SCCS file format internally and can be considered successors to SCCS.<ref>{{cite web|title=revtool|work=BitKeeper Documentation|url=https://www.bitkeeper.org/man/revtool.html}}</ref><ref>{{cite web|title=Introduction to Sun WorkShop TeamWare|url=https://docs.oracle.com/cd/E19957-01/806-3573/intro.html|website=docs.oracle.com|access-date=10 September 2016}}</ref>

On BSD systems, the SCCSID is replaced by a RCSID starting and ending with {{mono|$}}; the corresponding tool is {{mono|ident}}.<ref>{{Man|1|ident|NetBSD}}</ref> This system is originally used by [[Revision Control System|RCS]] and added automatically on checkout. The resulting source code revision control identifiers are documented in the [[NetBSD]]<ref>{{cite web|title=src/share/misc/style revision 1.64|url=http://cvsweb.netbsd.org/bsdweb.cgi/src/share/misc/style?rev=1.64&content-type=text/x-cvsweb-markup|publisher=NetBSD CVS repository}}</ref> and [[FreeBSD]]<ref>{{Man|9|style|FreeBSD}}</ref> style guides for their own code bases. NetBSD defines the custom keyword {{mono|$NetBSD: ...$}} while FreeBSD defines {{mono|$FreeBSD: ...$}} and a macro renamed {{mono|__FBSDID}}.

The SRC version control system can also use the SCCS file format internally (or [[Revision Control System|RCS]]'s) and aims to provide a better user interface for SCCS while still managing only single-file projects.<ref>{{cite web |url=http://www.catb.org/esr/src/ |title=Resource page for src 1.29 |author=<!--Not stated--> |date=January 21, 2022 |access-date=November 28, 2022 |quote=}}</ref>
