RCS (Revision Control System)

RCS (Revision Control System) is a tool used by developers to manage different versions of a file, such as source code. It tracks changes over time, allowing users to see what was modified, revert to previous versions if needed, and collaborate more efficiently. RCS stores each change as a new version, maintaining a history that helps in understanding the evolution of a file. It's particularly useful for small projects or individual work, ensuring that progress is organized and that older versions are preserved for reference or recovery.
