CVS

CVS is a widely-used version control system which plays a crucial role in Source Configuration Management (SCM). It enables you to keep a record of the history of source files and documents. Equipped with the capability to perform functions similar to those of RCS, PRCS and Aegis, CVS qualifies as a production quality system, consistently being adopted by free software projects and businesses worldwide.

CVS boasts several significant advantages over RCS, such as the ability to run your custom scripts to enforce site-specific policies or log CVS activities. The client/server CVS feature enables geographically-scattered developers with slow modems to function as a cohesive team. The version history could be stored on one central server while each client machine has a copy of files that each developer is working on.

In cases where several teams or developers wish to maintain their version of files based on geography and/or policy, CVS offers an option to import a version from a vendor branch even if they aren't using CVS. Using this feature, CVS syncs the changes from the vendor branch with the most recent files.

Unreserved checkouts are another one of CVS's notable features. It allows more than one developer to work on the same file simultaneously. CVS offers a flexible modules database that provides a symbolic mapping of names to the different components of a larger software distribution, making it easy to manage. Additionally, CVS operates in server mode, supporting local repositories on Windows 95/NT.

Overall, CVS is an efficient version control system that offers an exceptional user experience, enhanced flexibility, and remarkable versatility that seamlessly bridges geographic and technological barriers.
